There is bug in DG2 where if the CCS contexts switches out while the RCS
is running it can cause memory corruption. To workaround this add an
atomic to a memory address with a value 1 and semaphore wait to the same
address for a value of 0. The GuC firmware is responsible for writing 0
to the memory address when it is safe for the context to switch out.

There are some workarounds for DG2 that are implemented in the GuC
firmware. However, the KMD is required to enable these by setting the
appropriate flag as GuC does not know what platform it is running on.

Initiating a reset when the command streamer is not idle or in the
middle of executing an MI_FORCE_WAKE can result in a hang. Multiple
command streamers can be part of a single reset domain, so resetting one
would mean resetting all command streamers in that domain.
To workaround this, before initiating a reset, ensure that all command
streamers within that reset domain are either IDLE or are not executing
a MI_FORCE_WAKE.
Enable GuC PRE_PARSER WA bit so that GuC follows the WA sequence when
initiating engine-resets.
For gt-resets, ensure that i915 applies the WA sequence.
Opens to address in future patches:
- The part of the WA to wait for pending forcewakes is also applicable
to execlists backend.
- The WA also needs to be applied for gen11

Prior to doing a reset, SW must ensure command streamer is stopped,
as a workaround, to eliminate a race condition in GPM flow.
Setting both the ring stop and prefetch disable bits, will cause the
command streamer to halt.

Newer platforms have DSS that aren't necessarily available for both
geometry and compute, two queries will need to exist. This introduces
the first, when passing a valid engine class and engine instance in the
flags returns a topology describing geometry.
Based on past discussion, we currently only support this new query item
on Xe_HP and beyond; earlier platforms do not need to worry about
geometry and compute pipelines having access to different topology and
should continue to use the existing topology query.
v2: fix white space errors
v3: change flags from hosting 2 8 bit numbers to holding a
i915_engine_class_instance struct

The latest GuC firmware drops the context descriptor pool in favour of
passing all creation data in the create H2G. It also greatly simplifies
the work queue and removes the process descriptor used for multi-LRC
submission. So, remove all mention of LRC and process descriptors and
update the registration code accordingly.
Unfortunately, the new API also removes the ability to set default
values for the scheduling policies at context registration time.
Instead, a follow up H2G must be sent. The individual scheduling
policy update H2G commands are also dropped in favour of a single KLV
based H2G. So, change the update wrappers accordingly and call this
during context registration..
Of course, this second H2G per registration might fail due to being
backed up. The registration code has a complicated state machine to
cope with the actual registration call failing. However, if that works
then there is no support for unwinding if a further call should fail.
Unwinding would require sending a H2G to de-register - but that can't
be done because the CTB is already backed up.
So instead, add a new flag to say whether the context has a pending
policy update. This is set if the policy H2G fails at registration
time. The submission code checks for this flag and retries the policy
update if set. If that call fails, the submission path early exists
with a retry error. This is something that is already supported for
other reasons.

When we are swapping out the local memory obj on flat-ccs capable platform,
we need to capture the ccs data too along with main meory and we need to
restore it when we are swapping in the content.
When lmem object is swapped into a smem obj, smem obj will
have the extra pages required to hold the ccs data corresponding to the
lmem main memory. So main memory of lmem will be copied into the initial
pages of the smem and then ccs data corresponding to the main memory
will be copied to the subsequent pages of smem. ccs data is 1/256 of
lmem size.
Swapin happens exactly in reverse order. First main memory of lmem is
restored from the smem's initial pages and the ccs data will be restored
from the subsequent pages of smem.
Extracting and restoring the CCS data is done through a special cmd called
XY_CTRL_SURF_COPY_BLT

On Xe-HP and later devices, dedicated compression control state (CCS)
stored in local memory is used for each surface, to support the
3D and media compression formats.
The memory required for the CCS of the entire local memory is 1/256 of
the local memory size. So before the kernel boot, the required memory
is reserved for the CCS data and a secure register will be programmed
with the CCS base address
So when an object is allocated in local memory, dont need to explicitly
allocate the space for ccs data. But when the obj is evicted into the
smem, to hold the compression related data along with the obj extra space
is needed in smem. i.e obj_size + (obj_size/256).
Hence when a smem pages are allocated for an obj with lmem placement
possibility we create with the extra pages required for the ccs data for
the obj size.

Merge tag 'powerpc-5.18-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc fixes from Michael Ellerman:
- Fix KVM "lost kick" race, where an attempt to pull a vcpu out of the
guest could be lost (or delayed until the next guest exit).
- Disable SCV (system call vectored) when PR KVM guests could be run.
- Fix KVM PR guests using SCV, by disallowing AIL != 0 for KVM PR
guests.
- Add a new KVM CAP to indicate if AIL == 3 is supported.
- Fix a regression when hotplugging a CPU to a memoryless/cpuless node.
- Make virt_addr_valid() stricter for 64-bit Book3E & 32-bit, which
fixes crashes seen due to hardened usercopy.
- Revert a change to max_mapnr which broke HIGHMEM.
Thanks to Christophe Leroy, Fabiano Rosas, Kefeng Wang, Nicholas Piggin,
and Srikar Dronamraju.

If objdump writes to stderr it can block waiting for it to be read. As
perf doesn't read stderr then progress stops with perf waiting for
stdout output.

The `perf --list-cmds` output prints only internal commands, although
there is no reason for that from users' perspective.
Adding the external commands to commands array with NULL function
pointer allows printing all perf commands while not changing the logic
of command handler selection.

If a perf event doesn't fit into remaining buffer space return NULL to
remap buf and fetch the event again.
Keep the logic to error out on inadequate input from fuzzing.
This fixes perf failing on ChromeOS (with 32b userspace):
$ perf report -v -i perf.data
...
prefetch_event: head=0x1fffff8 event->header_size=0x30, mmap_size=0x2000000: fuzzed or compressed perf.data?
Error:

The 'perf bench epoll' testcase fails on systems with more than 1K CPUs.
Testcase: perf bench epoll all
Result snippet:
<<>>
Run summary [PID 106497]: 1399 threads monitoring on 64 file-descriptors for 8 secs.
perf: pthread_create: No such file or directory
<<>>
In epoll benchmarks (ctl, wait) pthread_create is invoked in do_threads
from respective bench_epoll_* function. Though the logs shows direct
failure from pthread_create, the actual failure is from
"sched_setaffinity" returning EINVAL (invalid argument).
This happens because the default mask size in glibc is 1024. To overcome
this 1024 CPUs mask size limitation of cpu_set_t, change the mask size
using the CPU_*_S macros.
Patch addresses this by fixing all the epoll benchmarks to use CPU_ALLOC
to allocate cpumask, CPU_ALLOC_SIZE for size, and CPU_SET_S to set the
mask.

The 'perf bench futex' testcase fails on systems with more than 1K CPUs.
Testcase: perf bench futex all
Failure snippet:
<<>>Running futex/hash benchmark...
perf: pthread_create: No such file or directory
<<>>
All the futex benchmarks (ie hash, lock-api, requeue, wake,
wake-parallel), pthread_create is invoked in respective bench_futex_*
function. Though the logs shows direct failure from pthread_create,
strace logs showed that actual failure is from "sched_setaffinity"
returning EINVAL (invalid argument).
This happens because the default mask size in glibc is 1024. To overcome
this 1024 CPUs mask size limitation of cpu_set_t, change the mask size

Since commit bb30acae4c ("perf report: Bail out --mem-mode if mem
info is not available") "perf mem report" and "perf report --mem-mode"
don't allow opening the file unless one of the events has
PERF_SAMPLE_DATA_SRC set.
SPE doesn't have this set even though synthetic memory data is generated
after it is decoded. Fix this issue by setting DATA_SRC on SPE events.
This has no effect on the data collected because the SPE driver doesn't
do anything with that flag and doesn't generate samples.
