The reserved_mem array must be statically allocated because it is used
prior to memblock being aware of all "no-map" or otherwise reserved
regions which have fixed physical addresses. Due to this limitation,
if one architecture/board has a large number of reserved_mem regions,
this limit must be raised for all.
In particular, certain new qcom boards currently have 63 reserved memory
regions, which when new features are added, pushes them over the existing
limit of 64.
A generalized breakdown by region type:
13 for linux-loaded device firmware
9 for guest-vms or inter-vm communication
15 cma heaps/dma-buf heaps
24 for bootloaders/hypervisor/secure-world devices or software
2 misc
Although this number could be reduced by a minor amount by combining
physically adjacent regions, this comes at the cost of losing
documention on what/who the regions are used by. In addition, combining
adjacent regions is not possible if there are phandles in devicetree
refering to the regions in question, such as "memory-region".

Add vendor hooks to capture when a USB audio interface is probed
and disconnected. These will allow for supporting offloading of
audio device handling to a co-processor.
The disconnect hook needs to be restricted as the additional
vendor handling may need to perform operations (such as
wait_for_completion) in non-atomic context.

Hence, modify loop_handle_cmd() such that it does not dereference 'cmd' nor

has not yet been completed. This patch fixes the following kernel crash:

Previously, there was a 100uS delay inserted after issuing an end transfer
command for specific controller revisions. This was due to the fact that
there was a GUCTL2 bit field which enabled synchronous completion of the
end transfer command once the CMDACT bit was cleared in the DEPCMD
register. Since this bit does not exist for all controller revisions and
the current implementation heavily relies on utizling the EndTransfer
command completion interrupt, add the delay back in for uses where the
interrupt on completion bit is not set, and increase the duration to 1ms
for the controller to complete the command.
An issue was seen where the USB request buffer was unmapped while the DWC3
controller was still accessing the TRB. However, it was confirmed that the
end transfer command was successfully submitted. (no end transfer timeout)
In situations, such as dwc3_gadget_soft_disconnect() and
__dwc3_gadget_ep_disable(), the dwc3_remove_request() is utilized, which
will issue the end transfer command, and follow up with
dwc3_gadget_giveback(). At least for the USB ep disable path, it is
required for any pending and started requests to be completed and returned
to the function driver in the same context of the disable call. Without
the GUCTL2 bit, it is not ensured that the end transfer is completed before
the buffers are unmapped.

[Why]

Use num_chans read from VBIOS to determine the available MALL size we can use
[How]
Define max_chans for DCN32 and DCN321.
If num_chans is max_chans, then return max_chans as we can access the
entire MALL space.
Otherwise, define avail_chans as the number of available channels we are
allowed instead.
Return corresponding number of channels back and use this to calculate
available MALL size.

[ Upstream commit afa4805799 ]
Gain control is badly documented in publicly available (including
leaked) documentation.
There is an AGC pre-gain in register 0x3a13, expressed as a 6-bit value
(plus an enable bit in bit 6). The driver hardcodes it to 0x43, which
one application note states is equal to x1.047. The documentation also
states that 0x40 is equel to x1.000. The pre-gain thus seems to be
expressed as in 1/64 increments, and thus ranges from x1.00 to x1.984.
What the pre-gain does is however unspecified.
There is then an AGC gain limit, in registers 0x3a18 and 0x3a19,
expressed as a 10-bit "real gain format" value. One application note
sets it to 0x00f8 and states it is equal to x15.5, so it appears to be
expressed in 1/16 increments, up to x63.9375.
The manual gain is stored in registers 0x350a and 0x350b, also as a
10-bit "real gain format" value. It is documented in the application
note as a Q6.4 values, up to x63.9375.
One version of the datasheet indicates that the sensor supports a
digital gain:
The OV5640 supports 1/2/4 digital gain. Normally, the gain is
controlled automatically by the automatic gain control (AGC) block.
It isn't clear how that would be controlled manually.
There appears to be no indication regarding whether the gain controlled
through registers 0x350a and 0x350b is an analogue gain only or also
includes digital gain. The words "real gain" don't necessarily mean
"combined analogue and digital gains". Some OmniVision sensors (such as
the OV8858) are documented as supoprting different formats for the gain
values, selectable through a register bit, and they are called "real
gain format" and "sensor gain format". For that sensor, we have (one of)
the gain registers documented as
0x3503[2]=0, gain[7:0] is real gain format, where low 4 bits are
fraction bits, for example, 0x10 is 1x gain, 0x28 is 2.5x gain
If 0x3503[2]=1, gain[7:0] is sensor gain format, gain[7:4] is coarse
gain, 00000: 1x, 00001: 2x, 00011: 4x, 00111: 8x, gain[7] is 1,
gain[3:0] is fine gain. For example, 0x10 is 1x gain, 0x30 is 2x gain,
0x70 is 4x gain
(The second part of the text makes little sense)
"Real gain" may thus refer to the combination of the coarse and fine
analogue gains as a single value.
The OV5640 0x350a and 0x350b registers thus appear to control analogue
gain. The driver incorrectly uses V4L2_CID_GAIN as V4L2 has a specific
control for analogue gain, V4L2_CID_ANALOGUE_GAIN. Use it.
If registers 0x350a and 0x350b are later found to control digital gain
as well, the driver could then restrict the range of the analogue gain
control value to lower than x64 and add a separate digital gain control.

[ Upstream commit 87c7ee67de ]
In the follow-up of commit fb3041d61f ("kbuild: fix SIGPIPE error
message for AR=gcc-ar and AR=llvm-ar"), Kees Cook pointed out that
tools should _not_ catch their own SIGPIPEs [1] [2].
Based on his feedback, LLVM was fixed [3].
However, Python's default behavior is to show noisy bracktrace when
SIGPIPE is sent. So, scripts written in Python are basically in the
same situation as the buggy llvm tools.
Example:
$ make -s allnoconfig
$ make -s allmodconfig
$ scripts/diffconfig .config.old .config | head -n1
-ALIX n
Traceback (most recent call last):
File "/home/masahiro/linux/scripts/diffconfig", line 132, in <module>
main()
File "/home/masahiro/linux/scripts/diffconfig", line 130, in main
print_config("+", config, None, b[config])
File "/home/masahiro/linux/scripts/diffconfig", line 64, in print_config
print("+%s %s" % (config, new_value))
BrokenPipeError: [Errno 32] Broken pipe
Python documentation [4] notes how to make scripts die immediately and
silently:
"""
Piping output of your program to tools like head(1) will cause a
SIGPIPE signal to be sent to your process when the receiver of its
standard output closes early. This results in an exception like
BrokenPipeError: [Errno 32] Broken pipe. To handle this case,
wrap your entry point to catch this exception as follows:
import os
import sys
def main():
try:
# simulate large output (your code replaces this loop)
for x in range(10000):
print("y")
# flush output here to force SIGPIPE to be triggered
# while inside this try block.
sys.stdout.flush()
except BrokenPipeError:
# Python flushes standard streams on exit; redirect remaining output
# to devnull to avoid another BrokenPipeError at shutdown
devnull = os.open(os.devnull, os.O_WRONLY)
os.dup2(devnull, sys.stdout.fileno())
sys.exit(1) # Python exits with error code 1 on EPIPE
if __name__ == '__main__':
main()
Do not set SIGPIPE’s disposition to SIG_DFL in order to avoid
BrokenPipeError. Doing that would cause your program to exit
unexpectedly whenever any socket connection is interrupted while
your program is still writing to it.
"""
Currently, tools/perf/scripts/python/intel-pt-events.py seems to be the
only script that fixes the issue that way.
tools/perf/scripts/python/compaction-times.py uses another approach
signal.signal(signal.SIGPIPE, signal.SIG_DFL) but the Python
documentation clearly says "Don't do it".
I cannot fix all Python scripts since there are so many.
I fixed some in the scripts/ directory.

[ Upstream commit b6b17a8b3e ]
Previously, R_ALPHA_LITERAL relocations would overflow for large kernel
modules.
This was because the Alpha's apply_relocate_add was relying on the kernel's
module loader to have sorted the GOT towards the very end of the module as it
was mapped into memory in order to correctly assign the global pointer. While
this behavior would mostly work fine for small kernel modules, this approach
would overflow on kernel modules with large GOT's since the global pointer
would be very far away from the GOT, and thus, certain entries would be out of
range.
This patch fixes this by instead using the Tru64 behavior of assigning the
global pointer to be 32KB away from the start of the GOT. The change made
in this patch won't work for multi-GOT kernel modules as it makes the
assumption the module only has one GOT located at the beginning of .got,
although for the vast majority kernel modules, this should be fine. Of the
kernel modules that would previously result in a relocation error, none of
them, even modules like nouveau, have even come close to filling up a single
GOT, and they've all worked fine under this patch.

[ Upstream commit 2a7ce82dc4 ]
In order for KCSAN to increase its likelihood of observing a data race,
it sets a watchpoint on memory accesses and stalls, allowing for
detection of conflicting accesses by other kernel threads or interrupts.
Stalls are implemented by injecting a call to udelay in instrumented code.
To prevent recursive instrumentation, exclude udelay from being instrumented.

[ Upstream commit dc222fa773 ]
The early paca and boot cpuid dance is complicated and currently does
not quite work as expected for boot cpuid != 0 cases.
early_init_devtree() currently allocates the paca_ptrs and boot cpuid
paca, but until that returns and early_setup() calls setup_paca(), this
thread is currently still executing with smp_processor_id() == 0.
One problem this causes is the paca_ptrs[smp_processor_id()] pointer is
poisoned, so valid_emergency_stack() (any backtrace) and any similar
users will crash.
Another is that the hardware id which is set here will not be returned
by get_hard_smp_processor_id(smp_processor_id()), but it would work
correctly for boot_cpuid == 0, which could lead to difficult to
reproduce or find bugs. The hard id does not seem to be used by the rest
of early_init_devtree(), it just looks like all this code might have
been put here to allocate somewhere to store boot CPU hardware id while
scanning the devtree.
Rearrange things so the hwid is put in a global variable like
boot_cpuid, and do all the paca allocation and boot paca setup in the
64-bit early_setup() after we have everything ready to go.
The paca_ptrs[0] re-poisoning code in early_setup does not seem to have
ever worked, because paca_ptrs[0] was never not-poisoned when boot_cpuid
is not 0.
