This reverts commit d18789f434. It breaks
the ABI and is not needed for now. It will come in at the next ABI
break so that future releases will be easier to manage.

This reverts commit 5847021f80, which is
commit 0e82d3715f upstream.
It is not needed, and the platform driver callback is being reverted
back to the original name due to ABI issues, so to preserve the build,
this change needs to be reverted.

Over time, we now have more gki_module headers being created at runtime,
yet they are not listed in the kernel/.gitignore file.
Fix that up so that when building, no "extra" files are seen to be
present and accidentally checked into the tree.

struct per_cpu_pages is no longer strictly local as PCP lists can be
drained remotely using a lock for protection. While the use of local_lock
works, it goes against the intent of local_lock which is for "pure CPU
local concurrency control mechanisms and not suited for inter-CPU
concurrency control" (Documentation/locking/locktypes.rst)
local_lock protects against migration between when the percpu pointer is
accessed and the pcp->lock acquired. The lock acquisition is a preemption
point so in the worst case, a task could migrate to another NUMA node and
accidentally allocate remote memory. The main requirement is to pin the
task to a CPU that is suitable for PREEMPT_RT and !PREEMPT_RT.
Replace local_lock with helpers that pin a task to a CPU, lookup the
per-cpu structure and acquire the embedded lock. It's similar to
local_lock without breaking the intent behind the API. It is not a
complete API as only the parts needed for PCP-alloc are implemented but in
theory, the generic helpers could be promoted to a general API if there
was demand for an embedded lock within a per-cpu struct with a guarantee
that the per-cpu structure locked matches the running CPU and cannot use
get_cpu_var due to RT concerns. PCP requires these semantics to avoid
accidentally allocating remote memory.

Some setups, notably NOHZ_FULL CPUs, are too busy to handle the per-cpu
drain work queued by __drain_all_pages(). So introduce a new mechanism to
remotely drain the per-cpu lists. It is made possible by remotely locking
'struct per_cpu_pages' new per-cpu spinlocks. A benefit of this new
scheme is that drain operations are now migration safe.
There was no observed performance degradation vs. the previous scheme.
Both netperf and hackbench were run in parallel to triggering the
__drain_all_pages(NULL, true) code path around ~100 times per second. The
new scheme performs a bit better (~5%), although the important point here
is there are no performance regressions vs. the previous mechanism.
Per-cpu lists draining happens only in slow paths.
Minchan Kim tested an earlier version and reported;
My workload is not NOHZ CPUs but run apps under heavy memory
pressure so they goes to direct reclaim and be stuck on
drain_all_pages until work on workqueue run.
unit: nanosecond
max(dur) avg(dur) count(dur)
166713013 487511.77786438033 1283
From traces, system encountered the drain_all_pages 1283 times and
worst case was 166ms and avg was 487us.
The other problem was alloc_contig_range in CMA. The PCP draining
takes several hundred millisecond sometimes though there is no
memory pressure or a few of pages to be migrated out but CPU were
fully booked.
Your patch perfectly removed those wasted time.

Currently the PCP lists are protected by using local_lock_irqsave to
prevent migration and IRQ reentrancy but this is inconvenient. Remote
draining of the lists is impossible and a workqueue is required and every
task allocation/free must disable then enable interrupts which is
expensive.
As preparation for dealing with both of those problems, protect the
lists with a spinlock. The IRQ-unsafe version of the lock is used
because IRQs are already disabled by local_lock_irqsave. spin_trylock
is used in combination with local_lock_irqsave() but later will be
replaced with a spin_trylock_irqsave when the local_lock is removed.
The per_cpu_pages still fits within the same number of cache lines after
this patch relative to before the series.
struct per_cpu_pages {
spinlock_t lock; /* 0 4 */
int count; /* 4 4 */
int high; /* 8 4 */
int batch; /* 12 4 */
short int free_factor; /* 16 2 */
short int expire; /* 18 2 */
/* XXX 4 bytes hole, try to pack */

/* size: 256, cachelines: 4, members: 7 */
/* sum members: 228, holes: 1, sum holes: 4 */
/* padding: 24 */
} __attribute__((__aligned__(64)));
There is overhead in the fast path due to acquiring the spinlock even
though the spinlock is per-cpu and uncontended in the common case. Page

The per_cpu_pages is cache-aligned on a standard x86-64 distribution
configuration but a later patch will add a new field which would push the
structure into the next cache line. Use only one list to store THP-sized
pages on the per-cpu list. This assumes that the vast majority of
THP-sized allocations are GFP_MOVABLE but even if it was another type, it
would not contribute to serious fragmentation that potentially causes a
later THP allocation failure. Align per_cpu_pages on the cacheline
boundary to ensure there is no false cache sharing.
After this patch, the structure sizing is;
struct per_cpu_pages {
int count; /* 0 4 */

Patch series "Drain remote per-cpu directly", v5.
Some setups, notably NOHZ_FULL CPUs, may be running realtime or
latency-sensitive applications that cannot tolerate interference due to
per-cpu drain work queued by __drain_all_pages(). Introduce a new
mechanism to remotely drain the per-cpu lists. It is made possible by
remotely locking 'struct per_cpu_pages' new per-cpu spinlocks. This has
two advantages, the time to drain is more predictable and other unrelated
tasks are not interrupted.
This series has the same intent as Nicolas' series "mm/page_alloc: Remote
per-cpu lists drain support" -- avoid interference of a high priority task
due to a workqueue item draining per-cpu page lists. While many workloads
can tolerate a brief interruption, it may cause a real-time task running
on a NOHZ_FULL CPU to miss a deadline and at minimum, the draining is
non-deterministic.
Currently an IRQ-safe local_lock protects the page allocator per-cpu
lists. The local_lock on its own prevents migration and the IRQ disabling
protects from corruption due to an interrupt arriving while a page
allocation is in progress.
This series adjusts the locking. A spinlock is added to struct
per_cpu_pages to protect the list contents while local_lock_irq is
ultimately replaced by just the spinlock in the final patch. This allows
a remote CPU to safely. Follow-on work should allow the spin_lock_irqsave
to be converted to spin_lock to avoid IRQs being disabled/enabled in most
cases. The follow-on patch will be one kernel release later as it is
relatively high risk and it'll make bisections more clear if there are any
problems.
Patch 1 is a cosmetic patch to clarify when page->lru is storing buddy pages
and when it is storing per-cpu pages.
Patch 2 shrinks per_cpu_pages to make room for a spin lock. Strictly speaking
this is not necessary but it avoids per_cpu_pages consuming another
cache line.
Patch 3 is a preparation patch to avoid code duplication.
Patch 4 is a minor correction.
Patch 5 uses a spin_lock to protect the per_cpu_pages contents while still
relying on local_lock to prevent migration, stabilise the pcp
lookup and prevent IRQ reentrancy.
Patch 6 remote drains per-cpu pages directly instead of using a workqueue.
Patch 7 uses a normal spinlock instead of local_lock for remote draining
This patch (of 7):
The page allocator uses page->lru for storing pages on either buddy or PCP
lists. Create page->buddy_list and page->pcp_list as a union with
page->lru. This is simply to clarify what type of list a page is on in
the page allocator.
No functional change intended.

Android 14 and later default to MGLRU [1] and field telemetry showed
occasional long tail latency (>100ms) in the reclaim path.
Tracing revealed priority inversion in the reclaim path. In
try_to_inc_max_seq(), when high priority tasks were blocked on
wait_event_killable(), the preemption of the low priority task to call
wake_up_all() caused those high priority tasks to wait longer than
necessary. In general, this problem is not different from others of its
kind, e.g., one caused by mutex_lock(). However, it is specific to MGLRU
because it introduced the new wait queue lruvec->mm_state.wait.
The purpose of this new wait queue is to avoid the thundering herd
problem. If many direct reclaimers rush into try_to_inc_max_seq(), only
one can succeed, i.e., the one to wake up the rest, and the rest who
failed might cause premature OOM kills if they do not wait. So far there
is no evidence supporting this scenario, based on how often the wait has
been hit. And this begs the question how useful the wait queue is in
practice.
Based on Minchan's recommendation, which is in line with his commit
6d4675e601 ("mm: don't be stuck to rmap lock on reclaim path") and the
rest of the MGLRU code which also uses trylock when possible, remove the
wait queue.

Currently, when regmap_raw_write() splits the data, it uses the
max_raw_write value defined for the bus. For any bus that includes
the target register address in the max_raw_write value, the chunked
transmission will always exceed the maximum transmission length.
To avoid this problem, subtract the length of the register and the
padding from the maximum transmission.

With FEAT_FGT, most bits in hfgwtr_el2 must be set to 1 to enable
trapping of MSR writes of certain registers. However, there is a
notable (and arguably curious) exception for nSMPRI_EL1 and
nTPIDR2_EL0 which must be set to 1 to _disable_ trapping of the
corresponding SME registers.
Make sure to initialize hfgwtr_el2 in the pKVM init params accordingly
to avoid accidentally enabling certain traps on hardware that supports
FEAT_FGT and FEAT_SME.

For some USB wifi devices, if enable this feature it will reduce the

In Synopsys's dwc3 data book:
In a few high speed devices when an IN request is sent within 900ns of the
ACK of the previous packet, these devices send a NAK. When connected to
these devices, if required, the software can disable the park mode if you
see performance drop in your system. When park mode is disabled,
pipelining of multiple packet is disabled and instead one packet at a time
is requested by the scheduler. This allows up to 12 NAKs in a micro-frame
and improves performance of these slow devices.

PCIe r6.0, sec 5.9, requires a 10ms delay between programming a device to
change to or from D3hot and the time the device is next accessed (unless
Readiness Notifications are used).
The 10ms value (PCI_PM_D3HOT_WAIT) doesn't appear directly here because
some chipsets require 120ms for devices *below* them (pci_pm_d3hot_delay)
and some devices require more or less than 10ms (dev->d3hot_delay).
But msleep(10) typically waits about *20*ms, which is more than we need.
Switch to usleep_range() to improve the delay accuracy.
Based on a commit from Sajid in the Pixel 6 kernel tree [1]. On a Pixel 6,
the 10ms delay for the Exynos PCIe device delayed for an average of 19ms.
Switching to usleep_range() decreased the resume time by about 9ms.

Android 14 and later default to MGLRU [1] and field telemetry showed
occasional long tail latency (>100ms) in the reclaim path.
Tracing revealed priority inversion in the reclaim path. In
try_to_inc_max_seq(), when high priority tasks were blocked on
wait_event_killable(), the preemption of the low priority task to call
wake_up_all() caused those high priority tasks to wait longer than
necessary. In general, this problem is not different from others of its
kind, e.g., one caused by mutex_lock(). However, it is specific to MGLRU
because it introduced the new wait queue lruvec->mm_state.wait.
The purpose of this new wait queue is to avoid the thundering herd
problem. If many direct reclaimers rush into try_to_inc_max_seq(), only
one can succeed, i.e., the one to wake up the rest, and the rest who
failed might cause premature OOM kills if they do not wait. So far there
is no evidence supporting this scenario, based on how often the wait has
been hit. And this begs the question how useful the wait queue is in
practice.
Based on Minchan's recommendation, which is in line with his commit
6d4675e601 ("mm: don't be stuck to rmap lock on reclaim path") and the
rest of the MGLRU code which also uses trylock when possible, remove the
wait queue.

On Android app cycle workloads, MGLRU showed a significant reduction in
workingset refaults although pgpgin/pswpin remained relatively unchanged.
This indicated MGLRU may be undercounting workingset refaults.
This has impact on userspace programs, like Android's LMKD, that monitor
workingset refault statistics to detect thrashing.
It was found that refaults were only accounted if the MGLRU shadow entry
was for a recently evicted folio. However, recently evicted folios should
be accounted as workingset activation, and refaults should be accounted
regardless of recency.
Fix MGLRU's workingset refault and activation accounting to more closely
match that of the conventional active/inactive LRU.

Disable CONFIG_ARM64_BTI_KERNEL since significant overhead has been observed
on systems that don't have BTI/PAC hardware support due to increased number
of NOPs added by these features.
BTI is not as important in kernels that have CFI enabled because the protection
these features offer overlap.
Keep PAC enabled and also enable dynamic SCS (CONFIG_UNWIND_PATCH_PAC_INTO_SCS)
which is available starting in v6.2. This removes SCS overhead on systems that
support PAC, and PAC overhead on systems that need SCS instead. This feature uses
runtime code patching, so it won't have the overhead of additional NOPs.

Implement dynamic shadow call stack support on Clang, by parsing the
unwind tables at init time to locate all occurrences of PACIASP/AUTIASP
instructions, and replacing them with the shadow call stack push and pop
instructions, respectively.
This is useful because the overhead of the shadow call stack is
difficult to justify on hardware that implements pointer authentication
(PAC), and given that the PAC instructions are executed as NOPs on
hardware that doesn't, we can just replace them without breaking
anything. As PACIASP/AUTIASP are guaranteed to be paired with respect to
manipulations of the return address, replacing them 1:1 with shadow call
stack pushes and pops is guaranteed to result in the desired behavior.

In order to allow arches to use code patching to conditionally emit the
shadow stack pushes and pops, rather than always taking the performance
hit even on CPUs that implement alternatives such as stack pointer
authentication on arm64, add a Kconfig symbol that can be set by the
arch to omit the SCS codegen itself, without otherwise affecting how
support code for SCS and compiler options (for register reservation, for
instance) are emitted.
Also, add a static key and some plumbing to omit the allocation of
shadow call stack for dynamic SCS configurations if SCS is disabled at
runtime.
