With the clkcsel binding we can drop the custom ti,bit-shift devicetree
property in favor of the standard reg property and reduce the number of
clocks to update for the make W-1 dtbs warnings.
Let's also add a comment for the clocksel clock that matches the

Architectures are required to provide four-byte cmpxchg() and 64-bit
architectures are additionally required to provide eight-byte cmpxchg().
However, there are cases where one-byte cmpxchg() would be extremely
useful. Therefore, provide cmpxchg_emu_u8() that emulates one-byte
cmpxchg() in terms of four-byte cmpxchg().
Note that this emulations is fully ordered, and can (for example) cause
one-byte cmpxchg_relaxed() to incur the overhead of full ordering.
If this causes problems for a given architecture, that architecture is
free to provide its own lighter-weight primitives.

Add (and export) __cmpxchg_u16(), teach __cmpxchg() to use it.
And get rid of manual truncation down to u8, etc. in there - the
only reason for those is to avoid bogus warnings about constant
truncation from sparse, and those are easy to avoid by turning
that switch into conditional expression.

__cmpxchg_u32() return value is unsigned int explicitly cast to

Conversion between u32 and unsigned long is tautological there,
and the only use of return value is to return it from
__cmpxchg() (which return unsigned long).
Get rid of explicit casts in __cmpxchg_u32() call, while we are
at it - normal conversions for arguments will do just fine.

In perf_adjust_freq_unthr_context(), it first starts the event and then
stop unnecessarily to adjust the sampling frequency if the event is
throttled.
For a throttled non-frequency event, it doesn't have a freq so no need
to adjust. Just starting the event would be ok.
For a frequency event, whether it's throttled or not, it needs to stop
before adjusting the frequency. That means it should not start the
even if it was throttled. I tried to skip calling the stop callback,
but it didn't work well since the event count might not be up to date.
It should call the stop callback with PERF_EF_UPDATE anyway.
However not calling start would prevent unnecessary MSR accesses (which
can be costly) for already stopped events as stop state is saved in the
hw config.

It was unnecessarily disabling and enabling PMUs for each event. It
should be done at PMU level. Add pmu_ctx->nr_freq counter to check it
at each PMU. As PMU context has separate active lists for pinned group
and flexible group, factor out a new function to do the job.
Another minor optimization is that it can skip PMUs w/ CAP_NO_INTERRUPT
even if it needs to unthrottle sampling events.

On x86 each struct cpu_hw_events maintains a table for counter assignment but
it missed to update one for the deleted event in x86_pmu_del(). This
can make perf_clear_dirty_counters() reset used counter if it's called
before event scheduling or enabling. Then it would return out of range
data which doesn't make sense.
The following code can reproduce the problem.
$ cat repro.c
#include <pthread.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <linux/perf_event.h>
#include <sys/ioctl.h>
#include <sys/mman.h>
#include <sys/syscall.h>
struct perf_event_attr attr = {
.type = PERF_TYPE_HARDWARE,
.config = PERF_COUNT_HW_CPU_CYCLES,
.disabled = 1,
};
void *worker(void *arg)
{
int cpu = (long)arg;
int fd1 = syscall(SYS_perf_event_open, &attr, -1, cpu, -1, 0);
int fd2 = syscall(SYS_perf_event_open, &attr, -1, cpu, -1, 0);
void *p;
do {
ioctl(fd1, PERF_EVENT_IOC_ENABLE, 0);
p = mmap(NULL, 4096, PROT_READ, MAP_SHARED, fd1, 0);
ioctl(fd2, PERF_EVENT_IOC_ENABLE, 0);
ioctl(fd2, PERF_EVENT_IOC_DISABLE, 0);
munmap(p, 4096);
ioctl(fd1, PERF_EVENT_IOC_DISABLE, 0);
} while (1);
return NULL;
}
int main(void)
{
int i;
int n = sysconf(_SC_NPROCESSORS_ONLN);
pthread_t *th = calloc(n, sizeof(*th));
for (i = 0; i < n; i++)
pthread_create(&th[i], NULL, worker, (void *)(long)i);
for (i = 0; i < n; i++)
pthread_join(th[i], NULL);
free(th);
return 0;
}
And you can see the out of range data using perf stat like this.
Probably it'd be easier to see on a large machine.

[why]
In current implemenation ODM mode is only reset when the last plane is
removed from dc state. For any dc validate we will always remove all
current planes and add new planes. However when switching from no planes
to 1 plane, ODM mode is not reset because no planes get removed. This
has caused an issue where we kept ODM combine when it should have been
remove when a plane is added. The change is to reset ODM mode when
adding the first plane.

If there are more than one device doing reset in parallel, the first
device will call kfd_suspend_all_processes() to evict all processes
on all devices, this call takes time to finish. other device will
start reset and recover without waiting. if the process has not been
evicted before doing recover, it will be restored, then caused page
fault.

[Why]
set_q_mode_offs don't get cleared after GPU reset, nexting SET_Q_MODE
packet to init shadow memory will be skiped, hence there has a page fault.
[How]
VM flush is needed after GPU reset, clear set_q_mode_offs when
emitting VM flush.

[WHY]
dynamic memory safety error detector (KASAN) catches and generates error
messages "BUG: KASAN: slab-out-of-bounds" as writeback connector does not
support certain features which are not initialized.
[HOW]
Skip them when connector type is DRM_MODE_CONNECTOR_WRITEBACK.
