From b60e31bf18a7064032dbcb73dcb5b58f8a00a110 Mon Sep 17 00:00:00 2001 From: Sanjay R Mehta Date: Thu, 4 Aug 2022 05:48:38 -0500 Subject: [PATCH 001/617] thunderbolt: Add DP OUT resource when DP tunnel is discovered If the boot firmware implements a connection manager of its own it may create a DisplayPort tunnel and will be handed off to Linux connection manager, but the DP OUT resource is not saved in the dp_resource list. This patch adds tunnelled DP OUT port to the dp_resource list once the DP tunnel is discovered.

It has additional bits for host and peripheral reset that need to cleared to use usb host and peripheral respectively. - The USB3_OTG_STA, USB3_OTG_INT_STA and USB3_OTG_INT_ENA registers have been moved and renamed to USB_PERI_DRD_STA, USB_PERI_DRD_INT_STA and USB_PERI_DRD_INT_E. - The IDMON bit used in the above regs for role detection have moved from bit 4 to bit 0. - RZ/V2M has an separate interrupt for DRD, i.e. for changes to IDMON. - There are reset lines for DRD and USBP - There is another clock, managed by runtime PM. Whilst the hardware can support 16 pipes, it is artifically limited based on the ram per pipe calculation. With the 4KB ram per pipe, we can support 9 pipes consisting of 4xIN pipes, 4xOUT pipes and PIPE0.

When a system includes multiple SoundWire links, the device number scope is limited to the link to which the device is attached. However, for integration/debug it can be convenient to have a unique device number across the system. This patch adds a 'dev_num_ida_min' field at the bus level, which when set will be used to allocate an IDA. The allocation happens when a hardware device reports as ATTACHED.

This is to avoid having a pending EP0 transfer in progress while attempting to stop active transfers and halting the controller. There were several instances seen where a soft disconnect was able to occur during early link negotiation, i.e. bus reset/conndone, which leads to the conndone handler re-configuring EPs while attempting to halt the controller, as DEP flags are cleared as part of the soft disconnect path. ep0out: cmd 'Start New Configuration' ep0out: cmd 'Set Endpoint Transfer Resource' ep0in: cmd 'Set Endpoint Transfer Resource' ep1out: cmd 'Set Endpoint Transfer Resource' ... event (00030601): Suspend [U3] event (00000101): Reset [U0] ep0out: req ffffff87e5c9e100 length 0/0 zsI ==> 0 event (00000201): Connection Done [U0] ep0out: cmd 'Start New Configuration' ep0out: cmd 'Set Endpoint Transfer Resource' In addition, if a soft disconnect occurs, EP0 events are still allowed to process, however, it will stall/restart during the SETUP phase. The host is still able to query for the DATA phase, leading to a xfernotready(DATA) event. Since none of the SETUP transfer parameters are populated, the xfernotready is treated as a "wrong direction" error, leading to a duplicate stall/restart routine. Add the proper softconnect/connected checks in sequences that are potentially involved during soft disconnect processing.

Since __dwc3_gadget_stop() is executed before polling, EP0 has been disabled, and events are being blocked. Allow xfercomplete events to be handled, so that cached SETUP packets can be read out from the internal controller memory. Without doing so, it will lead to endxfer timeouts, which results to controller halt failures.

Add USBIP_URB* flags to make this an explicit API and change the client and server to map them.

Server rx path (USBIP_CMD_SUBMIT): - Maps USBIP_URB_* to URB_* when it receives USBIP_CMD_SUBMIT packet.

Reconstructing this story is very strange: In b61312d353da ("oops handling: ensure that any oops is flushed to the mtdoops console") it is claimed that a printk(" "); flushed out the console buffer, which was removed in e3e8a75d2acf ("[PATCH] Extract and use wake_up_klogd()"). In todays kernels this is done way earlier in console_flush_on_panic with some really nasty tricks. I didn't bother to fully reconstruct this all, least because the call to bust_spinlock(0); gets moved every few years, depending upon how the wind blows (or well, who screamed loudest about the various issue each call site caused). Before that commit the only calls to console_unblank() where in s390 arch code. The other side here is the console->unblank callback, which was introduced in 2.1.31 for the vt driver. Which predates the console_unblank() function by a lot, which was added (without users) in 2.4.14.3. So pretty much impossible to guess at any motivation here. Also afaict the vt driver is the only (and always was the only) console driver implementing the unblank callback, so no idea why a call to console_unblank() was added for the mtdooops driver - the action actually flushing out the console buffers is done from console_unlock() only. Note that as prep for the s390 users the locking was adjusted in 2.5.22 (I couldn't figure out how to properly reference the BK commit from the historical git trees) from a normal semaphore to a trylock. Note that a copy of the direct unblank_screen() call was added to panic() in c7c3f05e341a ("panic: avoid deadlocks in re-entrant console drivers"), which partially inlined the bust_spinlocks(0); call. Long story short, I have no idea why the direct call to unblank_screen survived for so long (the infrastructure to do it properly existed for years), nor why it wasn't removed when the console_unblank() call was finally added. But it makes a ton more sense to finally do that than not - it's just better encapsulation to go through the console functions instead of doing a direct call, so let's dare. Plus it really does not make much sense to call the only unblank implementation there is twice, once without, and once with appropriate locking.

Digging through historical git trees shows that: - Added in 1.1.73, and I found absolutely no reason why. - Converted to atomic bitops in 2.1.125pre2, I guess as part of SMP enabling/bugfixes. - Converted to a proper spinlock in b0940003f25d ("vt: bitlock fix") because the hand-rolled atomic version lacked necessary memory barriers. Digging around in lore for that time period did also not shed further light. The only reason I think this might still be relevant today is that (to my understanding at least, ymmv) during an oops we might be printing without console_lock held. See console_flush_on_panic() and the comments in there - we flush out the console buffers irrespective of whether we managed to acquire the right locks. The strange thing is that this reason is fairly recent, because the console flushing was historically done without oops_in_progress set. This only changed in c7c3f05e341a ("panic: avoid deadlocks in re-entrant console drivers"), which removed the call to bust_spinlocks(0) (which decrements oops_in_progress again) before flushing out the console (which back then was open coded as a console_trylock/unlock pair). Note that this entire mess should be properly fixed in the printk/console layer, and not inflicted on each implementation. For now just document what's going on and check that in all other cases callers obey the locking rules. v2: WARN_CONSOLE_UNLOCKED already checks for oops_in_progress (something else that should be fixed I guess), hence remove the open-coded check I've had.

However, RCU dereference is currently only used in kernfs_notify(). Everywhere else, either we're holding the lock which protects it or know that the kernfs_open_node is pinned becaused we have a pointer to a kernfs_open_file which is hanging off of it. kernfs_deref_open_node() is used for the latter case - accessing kernfs_open_node from kernfs_open_file. The lifetime and visibility rules are simple and clear here. To someone who can access a kernfs_open_file, its kernfs_open_node is pinned and visible through of->kn->attr.open. Replace kernfs_deref_open_node() which simpler of_on(). The former takes both @kn and @of and RCU deref @kn->attr.open while sanity checking with @of. The latter takes @of and uses protected deref on of->kn->attr.open. As the return value can't be NULL, remove the error handling in the callers too. This shouldn't cause any functional changes.

The early exit test is factored into kernfs_should_drain_open_files() which is now tested by kernfs_drain_open_files()'s caller - kernfs_drain(). This isn't a meaningful optimization on its own but will enable future stand-alone kernfs_deactivate() implementation. v2: Chengming noticed that on->nr_to_release was leaking after ->open() failure. Fix it by telling kernfs_unlink_open_file() that it's called from the ->open() fail path and should dec the counter. Use kzalloc() to allocate kernfs_open_node so that the tracking fields are correctly initialized.

This ensures that the nodes will be deactivated and drained regardless of their states.

As a node was only deactivated on removal, this was used for 1. Drain optimization (removed by the previous patch). 2. To hide !activated nodes 3. To avoid double activations 4. Reject adding children to a node being removed 5. Skip activaing a node which is being removed. We want to decouple deactivation from removal so that nodes can be deactivated and hidden dynamically, which makes KERNFS_ACTIVATED useless for all of the above purposes. #1 is already gone. #2 and #3 can instead test whether the node is currently active. A new flag KERNFS_REMOVING is added to explicitly mark nodes which are being removed for #4 and #5. While this leaves KERNFS_ACTIVATED with no users, leave it be as it will be used in a following patch.

This is an one-way one-time-only transition. This patch introduces kernfs_show() which can toggle visibility dynamically. As the currently proposed use - toggling the cgroup pressure files - only requires operating on leaf nodes, for the sake of simplicity, restrict it as such for now. Hiding uses the same mechanism as deactivation and likewise guarantees that there are no in-flight operations on completion. KERNFS_ACTIVATED and KERNFS_HIDDEN are used to manage the interactions between activations and show/hide operations. A node is visible iff both activated & !hidden.

Each thread rewrite channels's descriptor as soon as device_issue_pending is called. It leads to the situation that the driver thinks that it uses the right descriptor in interrupt handler while channels's descriptor has been changed by other thread. The descriptor which in fact reported interrupt will not be handled any more, as well as its tx->callback. That's why timeout reports. With current fixes channels' descriptor changes it's value only when it has been used. A new descriptor is acquired from vc->desc_issued queue that is already filled with descriptors that are ready to be sent. Threads have no direct access to DMA channel descriptor. In case of channel's descriptor is busy, try to submit to HW again when a descriptor is completed. In this case, vc->desc_issued may be empty when hisi_dma_start_transfer is called, so delete error reporting on this. Now it is just possible to queue a descriptor for further processing.

Unfortunately, they have different register layouts, so the origin driver cannot run on HiSilicon IP09 correctly. This patch enables the driver to adapt to HiSilicon IP09. HiSilicon IP09 offers 4 channels, each channel has a send queue, a complete queue and an interrupt to help to do tasks. This DMA engine can do memory copy between memory blocks.

SPDX-License-Identifier: GPL-2.0 + +======================= +STM32 DMA-MDMA chaining +======================= + + +Introduction +------------ + + This document describes the STM32 DMA-MDMA chaining feature. But before going + further, let's introduce the peripherals involved. + + To offload data transfers from the CPU, STM32 microprocessors (MPUs) embed + direct memory access controllers (DMA). + + STM32MP1 SoCs embed both STM32 DMA and STM32 MDMA controllers. STM32 DMA + request routing capabilities are enhanced by a DMA request multiplexer + (STM32 DMAMUX). + + **STM32 DMAMUX** + + STM32 DMAMUX routes any DMA request from a given peripheral to any STM32 DMA + controller (STM32MP1 counts two STM32 DMA controllers) channels. + + **STM32 DMA** + + STM32 DMA is mainly used to implement central data buffer storage (usually in + the system SRAM) for different peripheral. It can access external RAMs but + without the ability to generate convenient burst transfer ensuring the best + load of the AXI. + + **STM32 MDMA** + + STM32 MDMA (Master DMA) is mainly used to manage direct data transfers between + RAM data buffers without CPU intervention. It can also be used in a + hierarchical structure that uses STM32 DMA as first level data buffer + interfaces for AHB peripherals, while the STM32 MDMA acts as a second level + DMA with better performance. As a AXI/AHB master, STM32 MDMA can take control + of the AXI/AHB bus. + + +Principles +---------- + + STM32 DMA-MDMA chaining feature relies on the strengths of STM32 DMA and + STM32 MDMA controllers. + + STM32 DMA has a circular Double Buffer Mode (DBM). At each end of transaction + (when DMA data counter - DMA_SxNDTR - reaches 0), the memory pointers + (configured with DMA_SxSM0AR and DMA_SxM1AR) are swapped and the DMA data + counter is automatically reloaded. This allows the SW or the STM32 MDMA to + process one memory area while the second memory area is being filled/used by + the STM32 DMA transfer. + + With STM32 MDMA linked-list mode, a single request initiates the data array + (collection of nodes) to be transferred until the linked-list pointer for the + channel is null. The channel transfer complete of the last node is the end of + transfer, unless first and last nodes are linked to each other, in such a + case, the linked-list loops on to create a circular MDMA transfer. + + STM32 MDMA has direct connections with STM32 DMA. This enables autonomous + communication and synchronization between peripherals, thus saving CPU + resources and bus congestion. Transfer Complete signal of STM32 DMA channel + can triggers STM32 MDMA transfer. STM32 MDMA can clear the request generated + by the STM32 DMA by writing to its Interrupt Clear register (whose address is + stored in MDMA_CxMAR, and bit mask in MDMA_CxMDR). + + .. table:: STM32 MDMA interconnect table with STM32 DMA + + +--------------+----------------+-----------+------------+ + | STM32 DMAMUX | STM32 DMA | STM32 DMA | STM32 MDMA | + | channels | channels | Transfer | request | + | | | complete | | + | | | signal | | + +==============+================+===========+============+ + | Channel *0* | DMA1 channel 0 | dma1_tcf0 | *0x00* | + +--------------+----------------+-----------+------------+ + | Channel *1* | DMA1 channel 1 | dma1_tcf1 | *0x01* | + +--------------+----------------+-----------+------------+ + | Channel *2* | DMA1 channel 2 | dma1_tcf2 | *0x02* | + +--------------+----------------+-----------+------------+ + | Channel *3* | DMA1 channel 3 | dma1_tcf3 | *0x03* | + +--------------+----------------+-----------+------------+ + | Channel *4* | DMA1 channel 4 | dma1_tcf4 | *0x04* | + +--------------+----------------+-----------+------------+ + | Channel *5* | DMA1 channel 5 | dma1_tcf5 | *0x05* | + +--------------+----------------+-----------+------------+ + | Channel *6* | DMA1 channel 6 | dma1_tcf6 | *0x06* | + +--------------+----------------+-----------+------------+ + | Channel *7* | DMA1 channel 7 | dma1_tcf7 | *0x07* | + +--------------+----------------+-----------+------------+ + | Channel *8* | DMA2 channel 0 | dma2_tcf0 | *0x08* | + +--------------+----------------+-----------+------------+ + | Channel *9* | DMA2 channel 1 | dma2_tcf1 | *0x09* | + +--------------+----------------+-----------+------------+ + | Channel *10* | DMA2 channel 2 | dma2_tcf2 | *0x0A* | + +--------------+----------------+-----------+------------+ + | Channel *11* | DMA2 channel 3 | dma2_tcf3 | *0x0B* | + +--------------+----------------+-----------+------------+ + | Channel *12* | DMA2 channel 4 | dma2_tcf4 | *0x0C* | + +--------------+----------------+-----------+------------+ + | Channel *13* | DMA2 channel 5 | dma2_tcf5 | *0x0D* | + +--------------+----------------+-----------+------------+ + | Channel *14* | DMA2 channel 6 | dma2_tcf6 | *0x0E* | + +--------------+----------------+-----------+------------+ + | Channel *15* | DMA2 channel 7 | dma2_tcf7 | *0x0F* | + +--------------+----------------+-----------+------------+ + + STM32 DMA-MDMA chaining feature then uses a SRAM buffer.

Set controller specific parameters** + + First, use dmaengine_slave_config() with a struct dma_slave_config to + configure STM32 DMA channel. You just have to take care of DMA addresses, + the memory address (depending on the transfer direction) must point on your + SRAM buffer, and set (struct dma_slave_config).peripheral_size != 0. + + STM32 DMA driver will check (struct dma_slave_config).peripheral_size to + determine if chaining is being used or not. If it is used, then STM32 DMA + driver fills (struct dma_slave_config).peripheral_config with an array of + three u32 : the first one containing STM32 DMAMUX channel ID, the second one + the channel interrupt flag clear register address, and the third one the + channel Transfer Complete flag mask. + + Then, use dmaengine_slave_config with another struct dma_slave_config to + configure STM32 MDMA channel. Take care of DMA addresses, the device address + (depending on the transfer direction) must point on your SRAM buffer, and + the memory address must point to the buffer originally used for "classic" + DMA operation. Use the previous (struct dma_slave_config).peripheral_size + and .peripheral_config that have been updated by STM32 DMA driver, to set + (struct dma_slave_config).peripheral_size and .peripheral_config of the + struct dma_slave_config to configure STM32 MDMA channel. + :: + + struct dma_slave_config dma_conf; + struct dma_slave_config mdma_conf; + + memset(&dma_conf, 0, sizeof(dma_conf)); + [...] + config.direction = DMA_DEV_TO_MEM; + config.dst_addr = sram_dma_buf; // SRAM buffer + config.peripheral_size = 1; // peripheral_size != 0 => chaining + + dmaengine_slave_config(dma_chan, &dma_config); + + memset(&mdma_conf, 0, sizeof(mdma_conf)); + config.direction = DMA_DEV_TO_MEM; + mdma_conf.src_addr = sram_dma_buf; // SRAM buffer + mdma_conf.dst_addr = rx_dma_buf; // original memory buffer + mdma_conf.peripheral_size = dma_conf.peripheral_size; // <- dma_conf + mdma_conf.peripheral_config = dma_config.peripheral_config; // <- dma_conf + + dmaengine_slave_config(mdma_chan, &mdma_conf); + + **2. Get a descriptor for STM32 DMA channel transaction** + + In the same way you get your descriptor for your "classic" DMA operation, + you just have to replace the original sg_list (in case of + dmaengine_prep_slave_sg()) with the new sg_list using SRAM buffer, or to + replace the original buffer address, length and period (in case of + dmaengine_prep_dma_cyclic()) with the new SRAM buffer. + + **3. Get a descriptor for STM32 MDMA channel transaction** + + If you previously get descriptor (for STM32 DMA) with + + * dmaengine_prep_slave_sg(), then use dmaengine_prep_slave_sg() for + STM32 MDMA; + * dmaengine_prep_dma_cyclic(), then use dmaengine_prep_dma_cyclic() for + STM32 MDMA. + + Use the new sg_list using SRAM buffer (in case of dmaengine_prep_slave_sg()) + or, depending on the transfer direction, either the original DDR buffer (in + case of DMA_DEV_TO_MEM) or the SRAM buffer (in case of DMA_MEM_TO_DEV), the + source address being previously set with dmaengine_slave_config(). + + **4. Submit both transactions** + + Before submitting your transactions, you may need to define on which + descriptor you want a callback to be called at the end of the transfer + (dmaengine_prep_slave_sg()) or the period (dmaengine_prep_dma_cyclic()). + Depending on the direction, set the callback on the descriptor that finishes + the overal transfer: + + * DMA_DEV_TO_MEM: set the callback on the "MDMA" descriptor + * DMA_MEM_TO_DEV: set the callback on the "DMA" descriptor + + Then, submit the descriptors whatever the order, with dmaengine_tx_submit(). + + **5. Issue pending requests (and wait for callback notification)** + + As STM32 MDMA channel transfer is triggered by STM32 DMA, you must issue + STM32 MDMA channel before STM32 DMA channel. + + If any, your callback will be called to warn you about the end of the overal + transfer or the period completion. + + Don't forget to terminate both channels. STM32 DMA channel is configured in + cyclic Double-Buffer mode so it won't be disabled by HW, you need to terminate + it. STM32 MDMA channel will be stopped by HW in case of sg transfer, but not + in case of cyclic transfer. You can terminate it whatever the kind of transfer. + + **STM32 DMA-MDMA chaining DMA_MEM_TO_DEV special case** + + STM32 DMA-MDMA chaining in DMA_MEM_TO_DEV is a special case. Indeed, the + STM32 MDMA feeds the SRAM buffer with the DDR data, and the STM32 DMA reads + data from SRAM buffer. So some data (the first period) have to be copied in + SRAM buffer when the STM32 DMA starts to read. + + A trick could be pausing the STM32 DMA channel (that will raise a Transfer + Complete signal, triggering the STM32 MDMA channel), but the first data read + by the STM32 DMA could be "wrong". The proper way is to prepare the first SRAM + period with dmaengine_prep_dma_memcpy(). Then this first period should be + "removed" from the sg or the cyclic transfer. + + Due to this complexity, rather use the STM32 DMA-MDMA chaining for + DMA_DEV_TO_MEM and keep the "classic" DMA usage for DMA_MEM_TO_DEV, unless + you're not afraid. + +Resources +--------- + + Application note, datasheet and reference manual are available on ST website + (STM32MP1_). + + Dedicated focus on three application notes (AN5224_, AN4031_ & AN5001_) + dealing with STM32 DMAMUX, STM32 DMA and STM32 MDMA. + +.. _STM32MP1: https://www.st.com/en/microcontrollers-microprocessors/stm32mp1-series.html +.. _AN5224: https://www.st.com/resource/en/application_note/an5224-stm32-dmamux-the-dma-request-router-stmicroelectronics.pdf +.. _AN4031: https://www.st.com/resource/en/application_note/dm00046011-using-the-stm32f2-stm32f4-and-stm32f7-series-dma-controller-stmicroelectronics.pdf +.. _AN5001: https://www.st.com/resource/en/application_note/an5001-stm32cube-expansion-package-for-stm32h7-series-mdma-stmicroelectronics.pdf + +:Authors: + +- Amelie Delaunay \ No newline at end of file From b9a22954f08074b2d0126e45636eb77b66395ac5 Mon Sep 17 00:00:00 2001 From: Amelie Delaunay Date: Mon, 29 Aug 2022 17:46:44 +0200 Subject: [PATCH 207/617] dmaengine: stm32-dmamux: set dmamux channel id in dma features bitfield STM32 DMAMUX is used with STM32 DMA1 and DMA2: - DMAMUX channels 0 to 7 are connected to DMA1 channels 0 to 7 - DMAMUX channels 8 to 15 are connected to DMA2 channels 0 to 7 STM32 MDMA can be triggered by DMA1 and DMA2 channels transfer complete, and the "request line number" is the DMAMUX channel id (e.g. DMA2 channel 0 triggers MDMA with request line 8).

These registers are 32-bit hardware counters and the driver uses these counters to monitor the operational progress status for a channel, when transferring more than 4GB of data it was observed that these counters overflow and completion calculation of a operation gets affected and the transfer hangs indefinitely. This commit adds changes to decrease the byte count for every complete transaction so that these registers never overflow and the proper byte count statistics is maintained for ongoing transaction by the RT counters. Earlier uc->bcnt used to maintain a count of the completed bytes at driver side, since the RT counters maintain the statistics of current transaction now, the maintenance of uc->bcnt is not necessary.

Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues.

Avoid retaining bogus hardware states during resume-from-hibernation. Previously we had reset the hardware as part of preparing to reinstate the snapshot image. But we can do better now with the new PM framework, since we know exactly which resume operations are from hibernation. According to the commit 'cd1965db054e ("USB: ohci: move ohci_pci_{ suspend,resume} to ohci-hcd.c")' and commit '6ec4beb5c701 ("USB: new flag for resume-from-hibernation")', the flag "hibernated" is for resume-from-hibernation and it should be true when usb resume from disk. When this flag "hibernated" is set, the drivers will reset the hardware to get rid of any existing state and make sure resume from hibernation re-enumerates everything for ohci.

This moves the Intel specific NVM handling into a new structure that will be matched by the device type and the vendor ID. Do this for both routers and retimers. This makes it easier to extend the NVM support to cover new vendors and NVM image formats in the future.

The vla_item() takes a size and adds it to the total. It has a built in integer overflow check so if it encounters an integer overflow anywhere then it records the total as SIZE_MAX. However there is an issue here because the "lang_count*(needed_count+1)" multiplication can overflow. Technically the "lang_count + 1" addition could overflow too, but that would be detected and is harmless. Fix both using the new size_add() and size_mul() functions.

The bug results in a premature static_branch_disable when the 1st of 2 flags was disabled. The cited commit computed newflags, but then in the JUMP_LABEL block, failed to use that result, instead using just one of the terms in it. Using newflags instead made the code work properly. This is Vincents test-case, reduced. It needs the 2nd flag to demonstrate the bug, but it's explanatory here. pt_test() { echo 5 > /sys/module/dynamic_debug/verbose site="module tcp" # just one callsite echo " $site =_ " > /proc/dynamic_debug/control # clear it # A B ~A ~B for flg in +T +p "-T #broke here" -p; do echo " $site $flg " > /proc/dynamic_debug/control done; # A B ~B ~A for flg in +T +p "-p #broke here" -T; do echo " $site $flg " > /proc/dynamic_debug/control done } pt_test Fixes: 84da83a6ffc0 dyndbg: combine flags & mask into a struct, simplify with it CC: vincent.whitchurch@axis.com Acked-by: Jason Baron Acked-by: Daniel Vetter Signed-off-by: Jim Cromie Link: https://lore.kernel.org/r/20220904214134.408619-2-jim.cromie@gmail.com Signed-off-by: Greg Kroah-Hartman --- lib/dynamic_debug.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/lib/dynamic_debug.c b/lib/dynamic_debug.c index dd7f56af9aed..a56c1286ffa4 100644 --- a/lib/dynamic_debug.c +++ b/lib/dynamic_debug.c @@ -211,10 +211,11 @@ static int ddebug_change(const struct ddebug_query *query, continue; #ifdef CONFIG_JUMP_LABEL if (dp->flags & _DPRINTK_FLAGS_PRINT) { - if (!(modifiers->flags & _DPRINTK_FLAGS_PRINT)) + if (!(newflags & _DPRINTK_FLAGS_PRINT)) static_branch_disable(&dp->key.dd_key_true); - } else if (modifiers->flags & _DPRINTK_FLAGS_PRINT) + } else if (newflags & _DPRINTK_FLAGS_PRINT) { static_branch_enable(&dp->key.dd_key_true); + } #endif dp->flags = newflags; v4pr_info("changed %s:%d [%s]%s =%s\n", From 85d6b66d31c35158364058ee98fb69ab5bb6a6b1 Mon Sep 17 00:00:00 2001 From: Jim Cromie Date: Sun, 4 Sep 2022 15:40:39 -0600 Subject: [PATCH 249/617] dyndbg: fix module.dyndbg handling For CONFIG_DYNAMIC_DEBUG=N, the ddebug_dyndbg_module_param_cb() stub-fn is too permissive: bash-5.1# modprobe drm JUNKdyndbg bash-5.1# modprobe drm dyndbgJUNK [ 42.933220] dyndbg param is supported only in CONFIG_DYNAMIC_DEBUG builds [ 42.937484] ACPI: bus type drm_connector registered This caused no ill effects, because unknown parameters are either ignored by default with an "unknown parameter" warning, or ignored because dyndbg allows its no-effect use on non-dyndbg builds.

Use it, in several different ways, as follows: In lib/dynamic_debug.c: ddebug_add_module(): Alter params-list, replacing 2 args (array,index) with a struct _ddebug_info * containing them both, with room for expansion. This helps future-proof the function prototype against the looming addition of class-map info into the dyndbg-state, by providing a place to add more member fields later. NB: later add static struct _ddebug_info builtins_state declaration, not needed yet. ddebug_add_module() is called in 2 contexts: In dynamic_debug_init(), declare, init a struct _ddebug_info di auto-var to use as a cursor. Then iterate over the prdbg blocks of the builtin modules, and update the di cursor before calling _add_module for each. Its called from kernel/module/main.c:load_info() for each loaded module: In internal.h, alter struct load_info, replacing the dyndbg array,len fields with an embedded _ddebug_info containing them both; and populate its members in find_module_sections(). The 2 calling contexts differ in that _init deals with contiguous subranges of __dyndbgs[] section, packed together, while loadable modules are added one at a time. So rename ddebug_add_module() into outer/__inner fns, call __inner from _init, and provide the offset into the builtin __dyndbgs[] where the module's prdbgs reside. The cursor provides start, len of the subrange for each. The offset will be used later to pack the results of builtin __dyndbg_sites[] de-duplication, and is 0 and unneeded for loadable modules, Note: kernel/module/main.c includes for struct _ddeubg_info. This might be prone to include loops, since its also included by printk.h. Nothing has broken in robot-land on this. cc: Luis Chamberlain Signed-off-by: Jim Cromie Link: https://lore.kernel.org/r/20220904214134.408619-12-jim.cromie@gmail.com Signed-off-by: Greg Kroah-Hartman --- include/linux/dynamic_debug.h | 13 +++++++----- kernel/module/internal.h | 4 ++-- kernel/module/main.c | 18 ++++++++-------- lib/dynamic_debug.c | 40 +++++++++++++++++++++++++++-------- 4 files changed, 50 insertions(+), 25 deletions(-) diff --git a/include/linux/dynamic_debug.h b/include/linux/dynamic_debug.h index 8d9eec5f6d8b..6a2001250da1 100644 --- a/include/linux/dynamic_debug.h +++ b/include/linux/dynamic_debug.h @@ -51,12 +51,16 @@ struct _ddebug { #endif } __attribute__((aligned(8)));

to represent this directly in dyndbg, add a new 6-bit field: struct _ddebug.class_id. This gives us 64 classes, which should be more than enough. #> echo 0x012345678 > /sys/module/drm/parameters/debug All existing callsites are initialized with _DPRINTK_CLASS_DFLT, which is 2^6-1. This reserves 0-62 for use in new categorized/class'd pr_debugs, which fits perfectly with natural enums (ints: 0..N). Thats done by extending the init macro: DEFINE_DYNAMIC_DEBUG_METADATA() with _CLS(cls, ...) suffix, and redefing old name using extended name. Then extend the factory macro callchain with _cls() versions to provide the callsite.class_id, with old-names passing _DPRINTK_CLASS_DFLT. This sets us up to create class'd prdebug callsites (class'd callsites are those with .class_id != _DPRINTK_CLASS_DFLT).

DECLARE_DYNDBG_CLASSMAP(_var, _maptype, _base, classes...) is:: _var: name of the static struct var. user passes to module_param_cb() if they want a sysfs node. _maptype: this is hard-coded to DD_CLASS_TYPE_DISJOINT_BITS for now. _base: usually 0, it allows splitting 31 classes into subranges, so that multiple classes / sysfs-nodes can share the module's class-id space. classes: list of class_name strings, these are mapped to class-ids starting at _base. This class-names list must have a corresponding ENUM, with SYMBOLS that match the literals, and 1st enum val = _base. enum class_map_type has 4 values, on 2 factors:: - classes are disjoint/independent vs relative/xcontrol interface doesn't enforce the LEVELS relationship, so you could confusingly have V3 enabled, but V1 disabled. OTOH, the control iface already allows infinite tweaking of the underlying callsites; sysfs node readback can only tell the user what they previously wrote. 2. All dyndbg >control reduces to a query/command, includes +/-, which is at-root a kernel patching operation with +/- semantics. And the _NAMES handling exposes it to the user, making it API-adjacent. And its not just >control where +/- gets used (which is settled), the new place is with sysfs-nodes exposing _*_NAMES classes, and here its subtly different. _DISJOINT_NAMES: is simple, independent _LEVEL_NAMES: masks-on bits 0 ..

Alternatively, we could treat the +/- as half-duplex, where -L3 turns off L>2 (and ignores L1), and +L2 would turn on L<=2 (and ignore others).

It scans the classes/section its given, finds records where the module-name matches the module being added, and adds them to the module's maps list. No locking here, since the record isn't yet linked into the ddebug_tables list. It is called indirectly from 2 sources: - from load_module(), where it scans the module's __dyndbg_classes section, which contains DYNAMIC_DEBUG_CLASSES definitions from just the module. - from dynamic_debug_init(), where all DYNAMIC_DEBUG_CLASSES definitions of each builtin module have been packed together. This is why ddebug_attach_module_classes() checks module-name. NOTES Its (highly) likely that builtin classes will be ordered by module name (just like prdbg descriptors are in the __dyndbg section). So the list can be replaced by a vector (ptr + length), which will work for loaded modules too. This would imitate whats currently done for the _ddebug descriptors. That said, converting to vector,len is close to pointless; a small minority of modules will ever define a class-map, and almost all of them will have only 1 or 2 class-maps, so theres only a couple dozen pointers to save.

This protects each module's class-space, other than the default:31. The authors' choice of FOO is highly selective, giving isolation and/or coordinated sharing of FOOs. For example, only DRM modules should know and respond to DRM_UT_KMS. So this, combined with module's opt-in declaration of known classes, effectively privatizes the .class_id space for each module (or coordinated set of modules). Notes: For all "class FOO" queries, ddebug_find_valid_class() is called, it returns the map matching the query, and sets valid_class via an *outvar). If no "class FOO" is supplied, valid_class = _CLASS_DFLT. This insures that legacy queries do not trample on new class'd callsites, as they get added. Also add a new column to control-file output, displaying non-default class-name (when found) or the "unknown _id:", if it has not been (correctly) declared with one of the declarator macros.

This supports uses like: echo 0x3 > /sys/module/drm/parameters/debug IE add these: - int param_set_dyndbg_classes() - int param_get_dyndbg_classes() - struct kernel_param_ops param_ops_dyndbg_classes Following the model of kernel/params.c STANDARD_PARAM_DEFS, these are non-static and exported. This might be unnecessary here. get/set use an augmented kernel_param; the arg refs a new struct ddebug_class_param, which contains: - A ptr to user's state-store; a union of &ulong for drm.debug, &int for nouveau level debug. By ref'g the client's bit-state _var, code coordinates with existing code (like drm_debug_enabled) which uses it, so existing/remaining calls can work unchanged. Changing drm.debug to a ulong allows use of BIT() etc. - FLAGS: dyndbg.flags toggled by changes to bitmap. Usually just "p". - MAP: a pointer to struct ddebug_classes_map, which maps those class-names to .class_ids 0..N that the module is using. This class-map is declared & initialized by DECLARE_DYNDBG_CLASSMAP. - map-type: 4 enums DD_CLASS_TYPE_* select 2 input forms and 2 meanings. numeric input: DD_CLASS_TYPE_DISJOINT_BITS integer input, independent bits. ie: drm.debug DD_CLASS_TYPE_LEVEL_NUM integer input, 0..N levels classnames-list (comma separated) input: DD_CLASS_TYPE_DISJOINT_NAMES each name affects a bit, others preserved DD_CLASS_TYPE_LEVEL_NAMES names have level meanings, like kern_levels.h _NAMES - comma-separated classnames (with optional +-) _NUM - numeric input, 0-N expected _BITS - numeric input, 0x1F bitmap form expected _DISJOINT - bits are independent _LEVEL - (x /sys/module/drm/parameters/debug_catnames A naive _LEVEL_NAMES use, with one class, that sets all in the class-map according to (x /sys/module/test_dynamic_debug/parameters/p_level_names : problem solved echo -L1 > /sys/module/test_dynamic_debug/parameters/p_level_names Note this artifact: : this is same as prev cmd (due to +/-) echo L0 > /sys/module/test_dynamic_debug/parameters/p_level_names : this is "even-more" off, but same wo __pr_debug_class(L0, ".."). echo -L0 > /sys/module/test_dynamic_debug/parameters/p_level_names A stress-test/make-work usage (kid toggling a light switch): echo +L7,L0,L7,L0,L7,L0,L7,L0,L7,L0,L7,L0,L7 \ > /sys/module/test_dynamic_debug/parameters/p_level_names ddebug_apply_class_bitmap(): inside-fn, works on bitmaps, receives new-bits, finds diffs vs client-bitvector holding "current" state, and issues exec_query to commit the adjustment. param_set_dyndbg_classes(): interface fn, sends _NAMES to param_set_dyndbg_classnames() and returns, falls thru to handle _BITS, _NUM internally, and calls ddebug_apply_class_bitmap(). Finishes by updating state. param_set_dyndbg_classnames(): handles classnames-list in loop, calls ddebug_apply_class_bitmap for each, then updates state. NOTES: _LEVEL_ is overlay on _DISJOINT_; inputs are converted to a bitmask, by the callbacks. IOW this is possible, and possibly confusing: echo class V3 +p > control echo class V1 -p > control IMO thats ok, relative verbosity is an interface property. _LEVEL_NUM maps still need class-names, even though the names are not usable at the sysfs interface (unlike with _NAMES style). The names are the only way to >control the classes. - It must have a "V0" name, something below "V1" to turn "V1" off. __pr_debug_cls(V0,..) is printk, don't do that. - "class names" is required at the >control interface. - relative levels are not enforced at >control _LEVEL_NAMES bear +/- signs, which alters the on-bit-pos by 1. IOW, +L2 means L0,L1,L2, and -L2 means just L0,L1. This kinda spoils the readback fidelity, since the L0 bit gets turned on by any use of any L*, except "-L0". All the interface uncertainty here pertains to the _NAMES features. Nobody has actually asked for this, so its practical (if a little tedious) to split it out.

Using them will fail, until the dyndbg-trace patches are added in. :#> echo 1 > T_disjoint [ 28.792489] dyndbg: disjoint: 0x1 > test_dynamic_debug.T_D2 [ 28.793848] dyndbg: query 0: "class D2_CORE +T" mod:* [ 28.795086] dyndbg: split into words: "class" "D2_CORE" "+T" [ 28.796467] dyndbg: op='+' [ 28.797148] dyndbg: unknown flag 'T' [ 28.798021] dyndbg: flags parse failed [ 28.798947] dyndbg: processed 1 queries, with 0 matches, 1 errs [ 28.800378] dyndbg: bit_0: -22 matches on class: D2_CORE -> 0x1 [ 28.801959] dyndbg: test_dynamic_debug.T_D2: updated 0x0 -> 0x1 [ 28.803974] dyndbg: total matches: -22 Signed-off-by: Jim Cromie Link: https://lore.kernel.org/r/20220904214134.408619-22-jim.cromie@gmail.com Signed-off-by: Greg Kroah-Hartman --- lib/test_dynamic_debug.c | 125 ++++++++++++++++++++++++++++++++++----- 1 file changed, 110 insertions(+), 15 deletions(-) diff --git a/lib/test_dynamic_debug.c b/lib/test_dynamic_debug.c index ba3882ca3e48..8dd250ad022b 100644 --- a/lib/test_dynamic_debug.c +++ b/lib/test_dynamic_debug.c @@ -10,57 +10,152 @@ #include +/* run tests by reading or writing sysfs node: do_prints */ + static void do_prints(void); /* device under test */ - -/* run tests by reading or writing sysfs node */ - static int param_set_do_prints(const char *instr, const struct kernel_param *kp) { do_prints(); return 0; } - static int param_get_do_prints(char *buffer, const struct kernel_param *kp) { do_prints(); return scnprintf(buffer, PAGE_SIZE, "did do_prints\n"); } - static const struct kernel_param_ops param_ops_do_prints = { .set = param_set_do_prints, .get = param_get_do_prints, }; - module_param_cb(do_prints, ¶m_ops_do_prints, NULL, 0600); -static void do_alpha(void) +/* + * Using the CLASSMAP api: + * - classmaps must have corresponding enum + * - enum symbols must match/correlate with class-name strings in the map. + * - base must equal enum's 1st value + * - multiple maps must set their base to share the 0-30 class_id space !! + * (build-bug-on tips welcome) + * Additionally, here: + * - tie together sysname, mapname, bitsname, flagsname + */ +#define DD_SYS_WRAP(_model, _flags) \ + static unsigned long bits_##_model; \ + static struct ddebug_class_param _flags##_model = { \ + .bits = &bits_##_model, \ + .flags = #_flags, \ + .map = &map_##_model, \ + }; \ + module_param_cb(_flags##_##_model, ¶m_ops_dyndbg_classes, &_flags##_model, 0600) + +/* numeric input, independent bits */ +enum cat_disjoint_bits { + D2_CORE = 0, + D2_DRIVER, + D2_KMS, + D2_PRIME, + D2_ATOMIC, + D2_VBL, + D2_STATE, + D2_LEASE, + D2_DP, + D2_DRMRES }; +DECLARE_DYNDBG_CLASSMAP(map_disjoint_bits, DD_CLASS_TYPE_DISJOINT_BITS, 0, + "D2_CORE", + "D2_DRIVER", + "D2_KMS", + "D2_PRIME", + "D2_ATOMIC", + "D2_VBL", + "D2_STATE", + "D2_LEASE", + "D2_DP", + "D2_DRMRES"); +DD_SYS_WRAP(disjoint_bits, p); +DD_SYS_WRAP(disjoint_bits, T); + +/* symbolic input, independent bits */ +enum cat_disjoint_names { LOW = 11, MID, HI }; +DECLARE_DYNDBG_CLASSMAP(map_disjoint_names, DD_CLASS_TYPE_DISJOINT_NAMES, 10, + "LOW", "MID", "HI"); +DD_SYS_WRAP(disjoint_names, p); +DD_SYS_WRAP(disjoint_names, T); + +/* numeric verbosity, V2 > V1 related */ +enum cat_level_num { V0 = 14, V1, V2, V3, V4, V5, V6, V7 }; +DECLARE_DYNDBG_CLASSMAP(map_level_num, DD_CLASS_TYPE_LEVEL_NUM, 14, + "V0", "V1", "V2", "V3", "V4", "V5", "V6", "V7"); +DD_SYS_WRAP(level_num, p); +DD_SYS_WRAP(level_num, T); + +/* symbolic verbosity */ +enum cat_level_names { L0 = 22, L1, L2, L3, L4, L5, L6, L7 }; +DECLARE_DYNDBG_CLASSMAP(map_level_names, DD_CLASS_TYPE_LEVEL_NAMES, 22, + "L0", "L1", "L2", "L3", "L4", "L5", "L6", "L7"); +DD_SYS_WRAP(level_names, p); +DD_SYS_WRAP(level_names, T); + +/* stand-in for all pr_debug etc */ +#define prdbg(SYM) __pr_debug_cls(SYM, #SYM " msg\n") + +static void do_cats(void) { - pr_debug("do alpha\n"); + pr_debug("doing categories\n"); + + prdbg(LOW); + prdbg(MID); + prdbg(HI); + + prdbg(D2_CORE); + prdbg(D2_DRIVER); + prdbg(D2_KMS); + prdbg(D2_PRIME); + prdbg(D2_ATOMIC); + prdbg(D2_VBL); + prdbg(D2_STATE); + prdbg(D2_LEASE); + prdbg(D2_DP); + prdbg(D2_DRMRES); } -static void do_beta(void) + +static void do_levels(void) { - pr_debug("do beta\n"); + pr_debug("doing levels\n"); + + prdbg(V1); + prdbg(V2); + prdbg(V3); + prdbg(V4); + prdbg(V5); + prdbg(V6); + prdbg(V7); + + prdbg(L1); + prdbg(L2); + prdbg(L3); + prdbg(L4); + prdbg(L5); + prdbg(L6); + prdbg(L7); } static void do_prints(void) { - do_alpha(); - do_beta(); + do_cats(); + do_levels(); } static int __init test_dynamic_debug_init(void) { pr_debug("init start\n"); - do_prints(); - pr_debug("init done\n"); return 0; } static void __exit test_dynamic_debug_exit(void) { - pr_debug("exiting\n"); + pr_debug("exited\n"); } module_init(test_dynamic_debug_init); From 408e532e80997be64caf8cdf45f2ff53c2279725 Mon Sep 17 00:00:00 2001 From: Vijaya Krishna Nivarthi Date: Wed, 7 Sep 2022 21:01:42 +0530 Subject: [PATCH 269/617] tty: serial: qcom-geni-serial: Replace hardcoded icc flags with macros.

That has been clearly a good and long overdue renaming, and it is clearly an improvement to the kernel build configuration that has shown to help managing the kernel build configuration in the last decade. However, rather than bravely and radically just deleting CONFIG_EMBEDDED, this commit gives CONFIG_EMBEDDED a new intended semantics, but keeps it open for future contributors to implement that intended semantics: A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Since then, this CONFIG_EMBEDDED implicitly had two purposes: - It can make even more options visible beyond what CONFIG_EXPERT makes visible. In other words, it may introduce another level of enabling the visibility of configuration options: always visible, visible with CONFIG_EXPERT and visible with CONFIG_EMBEDDED. - Set certain default values of some configurations differently, following the assumption that configuring a kernel build for an embedded system generally starts with a different set of default values compared to kernel builds for all other kind of systems. Considering the first purpose, at the point in time where CONFIG_EMBEDDED was renamed to CONFIG_EXPERT, CONFIG_EXPERT already made 130 more options become visible throughout all different menus for the kernel configuration. Over the last decade, this has gradually increased, so that currently, with CONFIG_EXPERT, roughly 170 more options become visible throughout all different menus for the kernel configuration. In comparison, currently with CONFIG_EMBEDDED enabled, just seven more options are visible, one in x86, one in arm, and five for the ChipIdea Highspeed Dual Role Controller. As the numbers suggest, these two levels of enabling the visibility of even more configuration options---beyond what CONFIG_EXPERT enables---never evolved to a good solution in the last decade. In other words, this additional level of visibility of configuration option with CONFIG_EMBEDDED compared to CONFIG_EXPERT has since its introduction never become really valuable. It requires quite some investigation to actually understand what is additionally visible and it does not differ significantly in complexity compared to just enabling CONFIG_EXPERT. This CONFIG_EMBEDDED---or any other config to show more detailed options beyond CONFIG_EXPERT---is unlikely to be valuable unless somebody puts significant effort in identifying how such visibility options can be properly split and creating clear criteria, when some config option is visible with CONFIG_EXPERT and when some config option is visible only with some further option enabled beyond CONFIG_EXPERT, such as CONFIG_EMBEDDED attempted to do. For now, it is much more reasonable to simply make those additional seven options that visible with CONFIG_EMBEDDED, visible with CONFIG_EXPERT, and then remove CONFIG_EMBEDDED. If anyone spends significant effort in structuring the visibility of config options, they may re-introduce suitable new config options simply as they see fit. Make the configs for usb chipidea glue drivers visible when CONFIG_EXPERT is enabled.

Linux had never actually used the value, but INIT_C_CC (on i386) did initialize it to ^O; unfortunately, it had a typo in the comment claiming that to be ^U. Most of the architectures copied the (correct) definition along with mistaken comment. alpha, powerpc and sparc tried to make the definition match comment. However, util-linux still resets it to ^O on any architecture, ^O is the historical value, kernel ignores it anyway and finally, Linus said "Just change everybody to do the same, nobody cares about VDISCARD".

So the include needs to be lifted out of there - we lift into tty_driver.h, serdev.h and places that pull asm/termios.h, but none of * linux/uaccess.h (obvious) * net/sock.h (pulls uaccess.h) * linux/{tty,tty_driver,serdev}.h (tty.h pulls tty_driver.h) That leaves us just with the include of UAPI asm/termios.h, which is what will resolve to if we simply remove non-UAPI header.

Currently the driver supports GMII/SGMII/QSGMII and partially RGMII. As it doesn't support all the other RGMII interfaces like RGMII_TXID/RXID/ID and it could run only at 1G. Therefore extend this for all the other speeds(10/100) and also allow the other interfaces.

Add a new compatible for J7200 to support the additional modes. In TI's J7200, each of the CPSW5G ethernet interfaces can act as a QSGMII or QSGMII-SUB port. The QSGMII interface is responsible for performing auto-negotiation between the MAC and the PHY while the rest of the interfaces are designated as QSGMII-SUB interfaces, indicating that they will not be taking part in the auto-negotiation process. To indicate the interface which will serve as the main QSGMII interface, add a property "ti,qsgmii-main-ports", whose value indicates the port number of the interface which shall serve as the main QSGMII interface. The rest of the interfaces are then assigned QSGMII-SUB mode by default. The property "ti,qsgmii-main-ports" is used to configure the CTRLMMR_ENETx_CTRL register. Depending on the device, it is possible for more than one QSGMII main port to exist. Thus, the property "ti,qsgmii-main-ports" is defined as an array of values in order to reuse the property for other devices.

The function cdns_update_slave_status() attempts to translate this into the current status of each of the slaves. However when there are multiple peripherals on a bus any slave that did not have a status change when the work function ran would not have it's status updated - the array is initialised to a value that equates to UNATTACHED and this can cause spurious reports that slaves had dropped off the bus. In the case where a slave has no status change or has multiple status changes the value from the last PING command is used.

If the missing device is one that is now showing as unenumerated it has been given a device ID so will report as attached next time sdw_handle_slave_status() runs. With the previous code the client driver would only see another ATTACHED notification because the UNATTACHED state was lost when sdw_handle_slave_status() bailed out after programming the device ID. This shows up most when the peripheral has to be reset after downloading updated firmware and there are multiple of these peripherals on the bus. They will all return to unenumerated state after the reset, and then there is a mix of unattached, attached and unenumerated PING states from the peripherals, as each is reset and they reboot.

Without this, it is possible for the UNATTACHED status to be missed and so the slave->status remains at ATTACHED. If slave->status never changes to UNATTACHED the child driver will never be notified of the UNATTACH, and the code in sdw_handle_slave_status() will skip the second part of enumeration because the slave->status has not changed. This scenario can happen because PINGs are handled in a workqueue function which is working from a snapshot of an old PING, and there is no guarantee when this function will run. A peripheral could report attached in the PING being handled by sdw_handle_slave_status(), but has since reverted to device #0 and is then found in the loop in sdw_program_device_num(). Previously the code would not have updated slave->status to UNATTACHED because it had not yet handled a PING where that peripheral had UNATTACHED.

Thus if the condition then re-asserts during the handling we won't lose it. This patch changes cdns_update_slave_status_work() to do this. The previous code cleared the interrupts after handling them. The problem with this is that when handling enumeration of devices the ATTACH statuses can be accidentally cleared and so some or all of the devices never complete their enumeration. Thus we can have a situation like this: - one or more devices are reverting to ID #0 - accumulated status bits indicate some devices attached and some on ID #0. (Remember: status bits are sticky until they are handled) - Because of device on #0 sdw_handle_slave_status() programs the device ID and exits without handling the other status, expecting to get an ATTACHED from this reprogrammed device. - The device immediately starts reporting ATTACHED in PINGs, which will assert its CDNS_MCP_SLAVE_INTSTAT_ATTACHED bit. - cdns_update_slave_status_work() clears INTSTAT0/1. If the initial status had CDNS_MCP_SLAVE_INTSTAT_ATTACHED bit set it will be cleared. - The ATTACHED change for the device has now been lost. - cdns_update_slave_status_work() clears CDNS_MCP_INT_SLAVE_MASK so if the new ATTACHED state had set it, it will be cleared without ever having been handled. Unless there is some other state change from another device to cause a new interrupt, the ATTACHED state of the reprogrammed device will never cause an interrupt so its enumeration will not be completed.

In that case there is no actual device still on #0. The early exit relies on there being a status change to ATTACHED on the reprogrammed device to trigger another call to sdw_handle_slave_status() which will then handle the status of all peripherals. If no device was actually programmed with an ID there won't be a new ATTACHED indication. This can lead to the status of other peripherals not being handled. The status passed to sdw_handle_slave_status() is obviously always from a point of time in the past, and may indicate accumulated unhandled events (depending how the bus manager operates). It's possible that a device ID is reprogrammed but the last PING status captured state just before that, when it was still reporting on ID #0. Then sdw_handle_slave_status() is called with this PING info, just before a new PING status is available showing it now on its new ID. So sdw_handle_slave_status() will receive a phantom report of a device on #0, but it will not find one.

Hence updating the macro name accordingly. The device ID 0x54ee is defined for the USB2 controller on the PCH sub-system for Alder Lake N platform. Hence updating the macro name accordingly. The device ID's defined for Alder Lake P is shared between Alder Lake P, Alder Lake PS and Alder Lake M. Hence updating the macro name to ADL from ADLP to make it common and keeping it aligned with the xHCI ID's naming convention. As we have two device controllers on Alder Lake platforms i.e. one on PCH sub-system and another on CPU sub-system(USB3), appending _PCH for the USB2 device ID macro to differentiate between the 2 ID's.

But the commit affects not only "Samsung Fit Flash" but also other usb storages that use the same controller and causes severe performance regression. # hdparm -t /dev/sda (without the quirk) Timing buffered disk reads: 622 MB in 3.01 seconds = 206.66 MB/sec # hdparm -t /dev/sda (with the quirk) Timing buffered disk reads: 220 MB in 3.00 seconds = 73.32 MB/sec The commit author mentioned that "Issue was reproduced after device has bad block", so this quirk should be applied when we have the timeout issue with a device that has bad blocks. We revert the commit so that we apply this quirk by adding kernel paramters using a bootloader or other ways when we really need it, without the performance regression with devices that don't have the issue.

Historically it has allowed enabling RS-485 even if no rts-gpio was specified in the device tree. That doesn't make any sense, so disable RS-485 on probe if rts-gpio is missing and disallow user space from enabling it.

Disabling the IRQ at the interrupt controller won't stop the UART from performing a DMA write to the address programmed in its MSI address register (zero) when it wants to signal an interrupt. The UARTs (in Ice Lake-D) implement PCI 2.1 style MSI without masking capability, so there is no way to mask the interrupt at the source PCI function level, except disabling the MSI capability entirely, but that would cause it to fall back to INTx# assertion, and the PCI specification prohibits disabling the MSI capability as a way to mask a function's interrupt service request. The MSI address register is zeroed by the hangup as the irq is freed. The interrupt is signalled during serial8250_do_startup() performing a THRE test that temporarily toggles THRI in IER. The THRE test currently occurs before UART's irq (and MSI address) is properly set up. Refactor serial8250_do_startup() such that irq is set up before the THRE test. The current irq setup code is intermixed with the timer setup code. As THRE test must be performed prior to the timer setup, extract it into own function and call it only after the THRE test. The ->setup_timer() needs to be part of the struct uart_8250_ops in order to not create circular dependency between 8250 and 8250_base modules.

Since commit 7df5081cbf5e ("serial: stm32: Add RS485 RTS GPIO control"), it can alternatively be controlled in software. That was done to allow RS-485 even if the RTS pin is unavailable because it's pinmuxed to a different function. However the commit neglected to deassert Transmit Enable upon invocation of the ->rs485_config() callback. Fix it. Avoid forward declarations by moving stm32_usart_tx_empty(), stm32_usart_rs485_rts_enable() and stm32_usart_rs485_rts_disable() further up in the driver.

By using natural enumeration, and moving the BIT(cat) into drm_debug_enabled(), the enum fits in 4 bits, allowing the category to be represented directly in pr_debug callsites, via the ddebug.class_id field. While this slightly pessimizes the bit-test in drm_debug_enabled(), using dyndbg with JUMP_LABEL will avoid the function entirely. NOTE: this change forecloses the possibility of doing: drm_dbg(DRM_UT_CORE|DRM_UT_KMS, "weird 2-cat experiment") but thats already strongly implied by the use of the enum itself; its not a normal enum if it can be 2 values simultaneously.

Use DECLARE_DYNDBG_CLASSMAP across DRM: - in .c files, since macro defines/initializes a record - in drivers, $mod_{drv,drm,param}.c ie where param setup is done, since a classmap is param related - in drm/drm_print.c since existing __drm_debug param is defined there, and we ifdef it, and provide an elaborated alternative. - in drm_*_helper modules: dp/drm_dp - 1st item in makefile target drivers/gpu/drm/drm_crtc_helper.c - random pick iirc. Since these modules all use identical CLASSMAP declarations (ie: names and .class_id's) they will all respond together to "class DRM_UT_*" query-commands: :#> echo class DRM_UT_KMS +p > /proc/dynamic_debug/control NOTES: This changes __drm_debug from int to ulong, so BIT() is usable on it. DRM's enum drm_debug_category values need to sync with the index of their respective class-names here. Then .class_id == category, and dyndbg's class FOO mechanisms will enable drm_dbg(DRM_UT_KMS, ...). Though DRM needs consistent categories across all modules, thats not generally needed; modules X and Y could define FOO differently (ie a different NAME => class_id mapping), changes are made according to each module's private class-map. No callsites are actually selected by this patch, since none are class'd yet.

In this case, the calls to _drm_*dbg are unreachable unless the callsite is enabled. So those calls can short-circuit their early do-nothing returns. Provide and use __drm_debug_enabled(), to do this when config'd, or the _raw flags-check otherwize. And since dyndbg is in use, lets also instrument the remaining users of drm_debug_enabled, by wrapping the _raw in a macro with a: pr_debug("todo: is this frequent enough to optimize ?\n"); For CONFIG_DRM_USE_DYNAMIC_DEBUG=n, do no site instrumenting at all, since JUMP_LABEL might be off, and we don't want to make work. With drm, amdgpu, i915, nouveau loaded, heres remaining uses of drm_debug_enabled(), which costs ~1.5kb data to control the pr_debug("todo:..")s. Some of those uses might be ok to use __drm_debug_enabled() by inspection, others might warrant conversion to use dyndbg Factory macros, and that would want callrate data to estimate the savings possible. TBH, any remaining savings are probably small; drm.debug covers the vast bulk of the uses.

NOTES: The descriptor gives these fns access to the decorator flags, but they do none of the dynamic-prefixing done by dynamic_emit_prefix(), which is currently static. DRM already has conventions for logging/messaging; just tossing optional decorations on top probably wouldn't help. Instead, existing flags (or new ones, perhaps 'sd' ala lspci) can be used to make current message conventions optional. This suggests a new drmdbg_prefix_emit() to handle prefixing locally. For CONFIG_DRM_USE_DYNAMIC_DEBUG=N, just pass null descriptor. desc->class_id is redundant with category parameter, but its availability is dependent on desc.

However a number of UART drivers interpret a set RTS bit as *assertion* instead of deassertion: Affected drivers include those using serial8250_em485_config() (except 8250_bcm2835aux.c) and some using mctrl_gpio (e.g. imx.c). Since the interpretation of the RTS bit is driver-specific, it is not suitable as a means to centrally deassert Transmit Enable in the serial core. Instead, the serial core must call on drivers to deassert it in their driver-specific way. One way to achieve that is to call ->rs485_config(). It implicitly deasserts Transmit Enable. So amend uart_configure_port() and uart_resume_port() to invoke uart_rs485_config(). That allows removing calls to uart_rs485_config() from drivers' ->probe() hooks and declaring the function static. Skip any invocation of ->set_mctrl() if RS485 is enabled. RS485 has no hardware flow control, so the modem control lines are irrelevant and need not be touched. When leaving RS485 mode, reset the modem control lines to the state stored in port->mctrl. That way, UARTs which are muxed between RS485 and RS232 transceivers drive the lines correctly when switched to RS232. (serial8250_do_startup() historically raises the OUT1 modem signal because otherwise interrupts are not signaled on ancient PC UARTs, but I believe that no longer applies to modern, RS485-capable UARTs and is thus safe to be skipped.) imx.c modifies port->mctrl whenever Transmit Enable is asserted and deasserted. Stop it from doing that so port->mctrl reflects the RS232 line state. 8250_omap.c deasserts Transmit Enable on ->runtime_resume() by calling ->set_mctrl(). Because that is now a no-op in RS485 mode, amend the function to call serial8250_em485_stop_tx(). fsl_lpuart.c retrieves and applies the RS485 device tree properties after registering the UART port. Because applying now happens on registration in uart_configure_port(), move retrieval of the properties ahead of uart_add_one_port().

charset=UTF-8 Content-Transfer-Encoding: 8bit Since commit edc6afc54968 ("tty: switch to ktermios and new framework") termios speed is no longer stored only in c_cflag member but also in new additional c_ispeed and c_ospeed members. If BOTHER flag is set in c_cflag then termios speed is stored only in these new members. Since commit 027b57170bf8 ("serial: core: Fix initializing and restoring termios speed") termios speed is available also in struct console. So properly restore also c_ispeed and c_ospeed members after suspend to fix restoring termios speed which is not represented by Bnnn constant.

This driver uses platform_driver_probe which is not compatible with deferred probing and won't be probed again later if probe function fails due to clock not being available at that time. This patch replaces the use of platform_driver_probe with platform_driver_register which will allow probing the driver later again when the clock control module will be available. The __init annotation has been dropped because it is not compatible with deferred probing. The code is not executed once and its memory cannot be freed.

While at it also make two additioanal minor cleanups: - mention Bjorn's new email ID in the document, and - add SDM845 in the comment line for the SoCs on which qcom,bam-v1.7.0 version is supported.

Qcom-adm instead provide error pointer when an error occur. This indirectly cause kernel panic for example for the nandc driver that checks only if the pointer returned by device_prep_slave_sg is not NULL. Returning an error pointer makes nandc think the device_prep_slave_sg function correctly completed and makes the kernel panics later in the code. While nandc is the one that makes the kernel crash, it was pointed out that the real problem is qcom-adm not following calling convention for that function. To fix this, drop returning error pointer and return NULL with an error log.

This means that certain ops can be disabled by the system administrator for certain wq. By default, all ops are available. A bitmap is used to store the ops due to total op size of 256 bits and it is more convenient to use a range list to specify which bits are enabled. One of the usage to support this is for VM migration between different iteration of devices. The newer ops are disabled in order to allow guest to migrate to a host that only support older ops. Another usage is to restrict the WQ to certain operations for QoS of performance. A sysfs of ops_config attribute is added per wq. It is only usable when the ops_config bit is set under WQ_CAP register. This means that this attribute will return -EOPNOTSUPP on DSA 1.x devices. The expected input is a range list for the bits per operation the WQ supports.

This leads to a problem when the eDMA driver has been probed, but the channels were not used. This scenario can happen when the DW PCIe driver probes eDMA driver successfully, but the PCI EPF driver decides not to use eDMA channels and use iATU instead for PCI transfers. In this case, the underlying device would be runtime suspended due to pm_runtime_enable() in dw_edma_probe() and the PCI EPF driver would have no knowledge of it. Ideally, the eDMA driver should not be the one doing the runtime PM of the parent device. The responsibility should instead belong to the client drivers like PCI EPF. So let's remove the runtime PM support from eDMA driver.

Some downstream ports (both internal to the built-in audio and network controllers, and external to USB sockets) may no longer be functional. The exact list of disabled ports (if any) changes from wakeup to wakeup. Ports remain in that state until the dock is power-cycled, or until the laptop is rebooted. Wakeup sources connected to the hubs (keyboard, WoL on the integrated gigabit controller) will wake the system up from suspend, but they may no longer work after wakeup (and in that case will no longer work as wakeup source in a subsequent suspend-wakeup cycle). This issue appears in the logs with messages such as: usb 1-6.1-port4: cannot disable (err = -71) usb 1-6-port2: cannot disable (err = -71) usb 1-6.1: clear tt 1 (80c0) error -71 usb 1-6-port4: cannot disable (err = -71) usb 1-6.4: PM: dpm_run_callback(): usb_dev_resume+0x0/0x10 [usbcore] returns -71 usb 1-6.4: PM: failed to resume async: error -71 usb 1-7: reset full-speed USB device number 5 using xhci_hcd usb 1-6.1-port1: cannot reset (err = -71) usb 1-6.1-port1: cannot reset (err = -71) usb 1-6.1-port1: cannot reset (err = -71) usb 1-6.1-port1: cannot reset (err = -71) usb 1-6.1-port1: cannot reset (err = -71) usb 1-6.1-port1: Cannot enable.

Maybe the USB cable is bad? usb 1-6.1-port1: cannot disable (err = -71) 2) Some USB devices cannot be enumerated properly. So far I have only seen the issue with USB 3.0 devices. The same devices work without problem directly connected to the host system, to other systems or to other hubs (even when those hubs are connected to the OneLink+ dock). One very reliable reproducer is this USB 3.0 HDD enclosure: 152d:9561 JMicron Technology Corp. / JMicron USA Technology Corp. Mobius I have seen it happen sporadically with other USB 3.0 enclosures, with controllers from different manufacturers, all self-powered. Typical messages in the logs: xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command usb 2-1.4: device not accepting address 6, error -62 xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command usb 2-1.4: device not accepting address 7, error -62 usb 2-1-port4: attempt power cycle xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command usb 2-1.4: device not accepting address 8, error -62 xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command usb 2-1.4: device not accepting address 9, error -62 usb 2-1-port4: unable to enumerate USB device Through trial and error, I found that the USB_QUIRK_RESET_RESUME solved the second issue. Further testing then uncovered the first issue. Test results are summarized in this table: ======================================================================================= Settings USB2 hotplug USB3 hotplug State after waking up --------------------------------------------------------------------------------------- power/control=auto works fails broken usbcore.autosuspend=-1 works works broken OR power/control=on power/control=auto works (1) works (1) works and USB_QUIRK_RESET_RESUME power/control=on works works works and USB_QUIRK_RESET_RESUME HUB_QUIRK_DISABLE_AUTOSUSPEND works works works and USB_QUIRK_RESET_RESUME ======================================================================================= In those results, the power/control settings are applied to both hubs, both on the USB2 and USB3 side, before each test. From those results, USB_QUIRK_RESET_RESUME is required to reset the hubs properly after a suspend-wakeup cycle, and the hubs must not autosuspend to work around the USB3 issue. A secondary effect of USB_QUIRK_RESET_RESUME is to prevent the hubs' upstream links from suspending (the downstream ports can still suspend). This secondary effect is used in results (1). It is enough to solve the USB3 problem. Setting USB_QUIRK_RESET_RESUME on those hubs is the smallest patch that solves both issues. Prior to creating this patch, I have used the USB_QUIRK_RESET_RESUME via the kernel command line for over a year without noticing any side effect. Thanks to Oliver Neukum @Suse for explanations of the operations of USB_QUIRK_RESET_RESUME, and requesting more testing.
