None of the pm_qos functions actually run in interrupt context; if some
driver calls pm_qos_update_target in interrupt context then it's already
broken. There's no need to disable interrupts while holding pm_qos_lock,
so don't do it.

An IRQ affinity notifier getting overwritten can point to some annoying
issues which need to be resolved, like multiple pm_qos objects being
registered to the same IRQ. Print out a warning when this happens to aid
debugging.

There's no reason to hold an RCU read lock the entire time while
optimistically spinning for a rwsem. This can needlessly lengthen RCU
grace periods and slow down synchronize_rcu() when it doesn't brute
force the RCU grace period via rcupdate.rcu_expedited=1.

Blindly ignoring frequency updates because of work_in_progress can leave
the CPUs at the wrong frequency for a long time. It's better to update the
frequency immediately than wait for a future event that might take a long
time to come. The irq_work code already ignores double queuing of work. So,
that part of the code is still safe when the work_in_progress flag is
ignored.

The schedutil driver sets sg_policy->next_freq to UINT_MAX on certain
occasions to discard the cached value of next freq:
- In sugov_start(), when the schedutil governor is started for a group
of CPUs.
- And whenever we need to force a freq update before rate-limit
duration, which happens when:
- there is an update in cpufreq policy limits.
- Or when the utilization of DL scheduling class increases.
In return, get_next_freq() doesn't return a cached next_freq value but
recalculates the next frequency instead.
But having special meaning for a particular value of frequency makes the
code less readable and error prone. We recently fixed a bug where the
UINT_MAX value was considered as valid frequency in
sugov_update_single().
All we need is a flag which can be used to discard the value of
sg_policy->next_freq and we already have need_freq_update for that. Lets
reuse it instead of setting next_freq to UINT_MAX.

Commit 152db033d775 (schedutil: Allow cpufreq requests to be made
even when kthread kicked) made changes to prevent utilization updates
from being discarded during processing a previous request, but it
left a small window in which that still can happen in the one-CPU
policy case. Namely, updates coming in after setting work_in_progress
in sugov_update_commit() and clearing it in sugov_work() will still
be dropped due to the work_in_progress check in sugov_update_single().
To close that window, rearrange the code so as to acquire the update
lock around the deferred update branch in sugov_update_single()
and drop the work_in_progress check from it.

Currently there is a chance of a schedutil cpufreq update request to be
dropped if there is a pending update request. This pending request can
be delayed if there is a scheduling delay of the irq_work and the wake
up of the schedutil governor kthread.
A very bad scenario is when a schedutil request was already just made,
such as to reduce the CPU frequency, then a newer request to increase
CPU frequency (even sched deadline urgent frequency increase requests)
can be dropped, even though the rate limits suggest that its Ok to
process a request. This is because of the way the work_in_progress flag
is used.
This patch improves the situation by allowing new requests to happen
even though the old one is still being processed. Note that in this
approach, if an irq_work was already issued, we just update next_freq
and don't bother to queue another request so there's no extra work being
done to make this happen.

Arm64 has a more optimized spinning loop (atomic_cond_read_acquire)
using wfe for spinlock that can boost performance of sibling threads
by putting the current cpu to a wait state that is broken only when
the monitored variable changes or an external event happens.
OSQ has a more complicated spinning loop. Besides the lock value, it
also checks for need_resched() and vcpu_is_preempted(). The check for
need_resched() is not a problem as it is only set by the tick interrupt
handler. That will be detected by the spinning cpu right after iret.
The vcpu_is_preempted() check, however, is a problem as changes to the
preempt state of of previous node will not affect the wait state. For
ARM64, vcpu_is_preempted is not currently defined and so is a no-op.
Will has indicated that he is planning to para-virtualize wfe instead
of defining vcpu_is_preempted for PV support. So just add a comment in
arch/arm64/include/asm/spinlock.h to indicate that vcpu_is_preempted()
should not be defined as suggested.
On a 2-socket 56-core 224-thread ARM64 system, a kernel mutex locking
microbenchmark was run for 10s with and without the patch. The
performance numbers before patch were:
Running locktest with mutex [runtime = 10s, load = 1]
Threads = 224, Min/Mean/Max = 316/123,143/2,121,269
Threads = 224, Total Rate = 2,757 kop/s; Percpu Rate = 12 kop/s
After patch, the numbers were:
Running locktest with mutex [runtime = 10s, load = 1]
Threads = 224, Min/Mean/Max = 334/147,836/1,304,787
Threads = 224, Total Rate = 3,311 kop/s; Percpu Rate = 15 kop/s
So there was about 20% performance improvement.

Scheduling-clock interrupts can arrive late in the CPU-offline process,
after idle entry and the subsequent call to cpuhp_report_idle_dead().
Once execution passes the call to rcu_report_dead(), RCU is ignoring
the CPU, which results in lockdep complaints when the interrupt handler
uses RCU:

This happens rarely, but can be forced by happen more often by
placing delays in cpuhp_report_idle_dead() following the call to
rcu_report_dead(). With this in place, the following rcutorture
scenario reproduces the problem within a few minutes:
tools/testing/selftests/rcutorture/bin/kvm.sh --cpus 8 --duration 5 --kconfig "CONFIG_DEBUG_LOCK_ALLOC=y CONFIG_PROVE_LOCKING=y" --configs "TREE04"
This commit uses the crude but effective expedient of moving the disabling
of interrupts within the idle loop to precede the cpu_is_offline()
check. It also invokes tick_nohz_idle_stop_tick() instead of
tick_nohz_idle_stop_tick_protected() to shut off the scheduling-clock
interrupt.

In order to boost during the period from when a new app is forked to the
time that it is added to the top-app cpuset (which is a signal to
subsequently boost again), boost for a short amount of time when zygote
forks. Not all processes forked from zygote are top apps, hence the
decoupled boosting setup.

Boost the CPU to the max for 1000 ms whenever the top app changes, which
improves app launch speeds and addresses jitter when switching between
apps. A check to make sure that the top-app's parent is zygote ensures
that a user-facing app is indeed what's added to the top app task group,
since app processes are forked from zygote.

This reverts commit dbc6f463a6fa80326c7f508245eb8ddae499d656.
This doesn't make sense for a few reasons. Firstly, upstream uses this
mutex code and it works fine on all arches; why should arm be any
different?
Secondly, once the mutex owner starts to spin on `wait_lock`,
preemption is disabled and the owner will be in an actively-running
state. The optimistic mutex spinning occurs when the lock owner is
actively running on a CPU, and while the optimistic spinning takes
place, no attempt to acquire `wait_lock` is made by the new waiter.
Therefore, it is guaranteed that new mutex waiters which optimistically
spin will not contend the `wait_lock` spin lock that the owner needs to
acquire in order to make forward progress.
Another potential source of `wait_lock` contention can come from tasks
that call mutex_trylock(), but this isn't actually problematic (and if
it were, it would affect the MUTEX_SPIN_ON_OWNER=n use-case too). This
won't introduce significant contention on `wait_lock` because the
trylock code exits before attempting to lock `wait_lock`, specifically
when the atomic mutex counter indicates that the mutex is already
locked. So in reality, the amount of `wait_lock` contention that can
come from mutex_trylock() amounts to only one task. And once it
finishes, `wait_lock` will no longer be contended and the previous
mutex owner can proceed with clean up.

cpu_clock() uses monotonic time, which skews when the system suspends,
making it difficult to interpret kmsg timestamps.
Add the sleep time offset to cpu_clock() in order to make kmsg timestamps
reflect the actual boot time.

In padata_alloc_pd, pd->cpu is set using the user-supplied cpumask
instead of the effective cpumask, and in this case cpumask_first picked
an offline CPU.
The offline CPU's reorder->list.next is NULL in padata_reorder because
the list wasn't initialized in padata_init_pqueues, which only operates
on CPUs in the effective mask.
Fix by using the effective mask in padata_alloc_pd.

[ Upstream commit 6fc4dbcf0276279d488c5fbbfabe94734134f4fa ]
The function padata_reorder will use a timer when it cannot progress
while completed jobs are outstanding (pd->reorder_objects > 0). This
is suboptimal as if we do end up using the timer then it would have
introduced a gratuitous delay of one second.
In fact we can easily distinguish between whether completed jobs
are outstanding and whether we can make progress. All we have to
do is look at the next pqueue list.
This patch does that by replacing pd->processed with pd->cpu so
that the next pqueue is more accessible.
A work queue is used instead of the original try_again to avoid
hogging the CPU.
Note that we don't bother removing the work queue in
padata_flush_queues because the whole premise is broken. You
cannot flush async crypto requests so it makes no sense to even
try. A subsequent patch will fix it by replacing it with a ref
counting scheme.

[ Upstream commit 1bd845bcb41d5b7f83745e0cb99273eb376f2ec5 ]
The parallel queue per-cpu data structure gets initialized only for CPUs
in the 'pcpu' CPU mask set. This is not sufficient as the reorder timer
may run on a different CPU and might wrongly decide it's the target CPU
for the next reorder item as per-cpu memory gets memset(0) and we might
be waiting for the first CPU in cpumask.pcpu, i.e. cpu_index 0.
Make the '__this_cpu_read(pd->pqueue->cpu_index) == next_queue->cpu_index'
compare in padata_get_next() fail in this case by initializing the
cpu_index member of all per-cpu parallel queues. Use -1 for unused ones.

commit 350ef88e7e922354f82a931897ad4a4ce6c686ff upstream.
If the algorithm we're parallelizing is asynchronous we might change
CPUs between padata_do_parallel() and padata_do_serial(). However, we
don't expect this to happen as we need to enqueue the padata object into
the per-cpu reorder queue we took it from, i.e. the same-cpu's parallel
queue.
Ensure we're not switching CPUs for a given padata object by tracking
the CPU within the padata object. If the serial callback gets called on
the wrong CPU, defer invoking padata_reorder() via a kernel worker on
the CPU we're expected to run on.

commit cf5868c8a22dc2854b96e9569064bb92365549ca upstream.
The reorder timer function runs on the CPU where the timer interrupt was
handled which is not necessarily one of the CPUs of the 'pcpu' CPU mask
set.
Ensure the padata_reorder() callback runs on the correct CPU, which is
one in the 'pcpu' CPU mask set and, preferrably, the next expected one.
Do so by comparing the current CPU with the expected target CPU. If they
match, call padata_reorder() right away. If they differ, schedule a work
item on the target CPU that does the padata_reorder() call for us.

Problem background: In the process of suspend, maybe some device suspend
callback failed in dpm_suspend_start()/dpm_prepare()/dpm_suspend().
Because it's after suspend_console(), so printf() is disabled now.
Currently we can see "Some devices failed to suspend, or early wake
event detected" by log_suspend_abort_reason() in bugreport. There are
many devices but we don't know which exactly device failed. So we
want to do a little change to record which device failed.
Note: I checked upstream LTS kernel, then I found the
patch can not be sent upstream, because it uses function
log_suspend_abort_reason() in wakeup_reason.c, the initial
patch(https://patchwork.kernel.org/patch/3827331/) for adding
/kernel/power/wakeup_reason.c is not accepted by upstream which
was merged in AOSP common kernels. So maybe the patch could
only be sent to AOSP common kernels.
Test: manual - Use modified version for daily use two days, from
bugreport we can see which device failed.

The new s2idle code in the 4.14 kernel (relative to 4.9) upends a
previously safe assumption that android wakeup logging relied upon: that
a wakeup caused by a wake-capable interrupt would never also see a
wakeup abort reason (i.e. related to a held wakesource that appears to
have prevented suspend from succeeding) logged in the same resume flow.
Specifically, where deep sleep flow in 4.9 and 4.14 as well as s2idle
flow in 4.9 only checked for abort reasons prior to noirq resume of
devices, 4.14's s2idle_loop always checks for abort reasons after noirq
resume of devices, which virtually ensures that an abort reason will be
logged for every wakeup.
In addition, the new s2idle_loop flow will log abort messages in the
kernel log - potentially even twice - despite no suspend abort having
occurred.
This change consists of two elements to address those issues (one
directly, the other indirectly):
* s2idle_loop() is modified to avoid redundant calls to
pm_wakeup_pending(), and it is only invoked after device resume if no
previous call has returned true
* s2idle_loop is also modified to invoke clear_wakeup_reasons() whenever
a partial wakeup results in looping around back into s2idle_enter,
clearing android wakeup reason logging at the same point where the
upstream kernel's builtin wakeup IRQ logging is also cleared.
It's worth noting that there may not actually be a valid case in our
architecture where the loop will, in fact, loop... even prior to this
change. That being the case, the second changes (the
clear_wakeup_reasons() call) may actually be superfluous. But this
change attempts to preserve the overall spirit of the s2idle_loop()
sequence as it exists from upstream, which is why the clear was added.
Fixes: 135560499
Change-Id: I56b52bfffd8bbcf9679444f01ba9fce8b8fbe490
Testing: Loaded onto device along with pending s2idle and soc driver
changes, ran for a while, and closely studied kernel log and
batterystats wakeup logging to ensure that no new brokenness appears to
have been added.
