f94b9707a1 drm/imx: parallel-display: switch to imx_legacy_bridge / drm_bridge_connector
Use the imx_legacy bridge driver instead of handlign display modes via
the connector node.

All existing usecases already support attaching using
the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag, while the imx_legacy bridge
doesn't support creating connector at all. Switch to
drm_bridge_connector at the same time.

cc3e8a216d drm/imx: add internal bridge handling display-timings DT node
i.MX DRM DT bindings allow using either a proper panel / bridge graph to
provide information about connected panels, or just a display-timings DT
node, describing just the timings and the flags. Add helper bridge
driver supporting the latter usecase. It will be used by both LDB and
parallel-display drivers.

b1934cd606 btrfs: zoned: handle broken write pointer on zones
Btrfs rejects to mount a FS if it finds a block group with a broken write
pointer (e.g, unequal write pointers on two zones of RAID1 block group).
Since such case can happen easily with a power-loss or crash of a system,
we need to handle the case more gently.

Handle such block group by making it unallocatable, so that there will be
no writes into it. That can be done by setting the allocation pointer at
the end of allocating region (= block_group->zone_capacity). Then, existing
code handle zone_unusable properly.

Having proper zone_capacity is necessary for the change. So, set it as fast
as possible.

We cannot handle RAID0 and RAID10 case like this. But, they are anyway
unable to read because of a missing stripe.

Fixes: 568220fa96 ("btrfs: zoned: support RAID0/1/10 on top of raid stripe tree")

20cee68f5b ext4: clear EXT4_GROUP_INFO_WAS_TRIMMED_BIT even mount with discard
Commit 3d56b8d2c7 ("ext4: Speed up FITRIM by recording flags in
ext4_group_info") speed up fstrim by skipping trim trimmed group. We
also has the chance to clear trimmed once there exists some block free
for this group(mount without discard), and the next trim for this group
will work well too.

For mount with discard, we will issue dicard when we free blocks, so
leave trimmed flag keep alive to skip useless trim trigger from
userspace seems reasonable. But for some case like ext4 build on
dm-thinpool(ext4 blocksize 4K, pool blocksize 128K), discard from ext4
maybe unaligned for dm thinpool, and thinpool will just finish this
discard(see process_discard_bio when begein equals to end) without
actually process discard. For this case, trim from userspace can really
help us to free some thinpool block.

So convert to clear trimmed flag for all case no matter mounted with
discard or not.

c543e24296 ext4: update delalloc data reserve spcae in ext4_es_insert_extent()
Now that we update data reserved space for delalloc after allocating
new blocks in ext4_{ind|ext}_map_blocks(), and if bigalloc feature is
enabled, we also need to query the extents_status tree to calculate the
exact reserved clusters. This is complicated now and it appears that
it's better to do this job in ext4_es_insert_extent(), because
__es_remove_extent() have already count delalloc blocks when removing
delalloc extents and __revise_pending() return new adding pending count,
we could update the reserved blocks easily in ext4_es_insert_extent().

We direct reduce the reserved cluster count when replacing a delalloc
extent. However, thers are two special cases need to concern about the
quota claiming when doing direct block allocation (e.g. from fallocate).

A),
fallocate a range that covers a delalloc extent but start with
non-delayed allocated blocks, e.g. a hole.

  hhhhhhh+ddddddd+ddddddd
  ^^^^^^^^^^^^^^^^^^^^^^^  fallocate this range

Current ext4_map_blocks() can't always trim the extent since it may
release i_data_sem before calling ext4_map_create_blocks() and raced by
another delayed allocation. Hence the EXT4_GET_BLOCKS_DELALLOC_RESERVE
may not set even when we are replacing a delalloc extent, without this
flag set, the quota has already been claimed by ext4_mb_new_blocks(), so
we should release the quota reservations instead of claim them again.

B),
bigalloc feature is enabled, fallocate a range that contains non-delayed
allocated blocks.

  |<         one cluster       >|
  hhhhhhh+hhhhhhh+hhhhhhh+ddddddd
  ^^^^^^^  fallocate this range

This case is similar to above case, the EXT4_GET_BLOCKS_DELALLOC_RESERVE
flag is also not set.

Hence we should release the quota reservations if we replace a delalloc
extent but without EXT4_GET_BLOCKS_DELALLOC_RESERVE set.

eba8c368c8 ext4: don't set EXTENT_STATUS_DELAYED on allocated blocks
Currently, we release delayed allocation reservation when removing
delayed extent from extent status tree (which also happens when
overwriting one extent with another one). When we allocated unwritten
extent under some delayed allocated extent, we don't need the
reservation anymore and hence we don't need to preserve the
EXT4_MAP_DELAYED status bit. Allocating the new extent blocks will
properly release the reservation.

8b8252884f ext4: optimize the EXT4_GET_BLOCKS_DELALLOC_RESERVE flag set
When doing block allocation, magic EXT4_GET_BLOCKS_DELALLOC_RESERVE
means the allocating range covers a range of delayed allocated clusters,
the blocks and quotas have already been reserved in ext4_da_map_blocks(),
we should update the reserved space and don't need to claim them again.

At the moment, we only set this magic in mpage_map_one_extent() when
allocating a range of delayed allocated clusters in the write back path,
it makes things complicated since we have to notice and deal with the
case of allocating non-delayed allocated clusters separately in
ext4_ext_map_blocks(). For example, it we fallocate some blocks that
have been delayed allocated, free space would be claimed again in
ext4_mb_new_blocks() (this is wrong exactily), and we can't claim quota
space again, we have to release the quota reservations made for that
previously delayed allocated clusters.

Move the position thats set the EXT4_GET_BLOCKS_DELALLOC_RESERVE to
where we actually do block allocation, it could simplify above handling
a lot, it means that we always set this magic once the allocation range
covers delalloc blocks, no need to take care of the allocation path.

aee1d55922 perf python: include "util/sample.h"
The 32-bit arm build system will complain:

tools/perf/util/python.c:75:28: error: field ‘sample’ has incomplete type
   75 |         struct perf_sample sample;

However, arm64 build system doesn't complain this.

The root cause is arm64 define "HAVE_KVM_STAT_SUPPORT := 1" in
tools/perf/arch/arm64/Makefile, but arm arch doesn't define this.
This will lead to kvm-stat.h include other header files on arm64 build
system, especially "util/sample.h" for util/python.c.

This will try to directly include "util/sample.h" for "util/python.c" to
avoid such build issue on arm platform.

287bd5cf06 perf lock contention: Fix spinlock and rwlock accounting
The spinlock and rwlock use a single-element per-cpu array to track
current locks due to performance reason.  But this means the key is
always available and it cannot simply account lock stats in the array
because some of them are invalid.

In fact, the contention_end() program in the BPF invalidates the entry
by setting the 'lock' value to 0 instead of deleting the entry for the
hashmap.  So it should skip entries with the lock value of 0 in the
account_end_timestamp().

Otherwise, it'd have spurious high contention on an idle machine:

  $ sudo perf lock con -ab -Y spinlock sleep 3
   contended   total wait     max wait     avg wait         type   caller

           8      4.72 s       1.84 s     590.46 ms     spinlock   rcu_core+0xc7

I don't believe it has contention on a spinlock longer than 1 second.
After this change, it only reports some small contentions.

1c7fb536e8 perf test pmu: Set uninitialized PMU alias to null
Commit 3e0bf9fde2 ("perf pmu: Restore full PMU name wildcard
support") adds a test case "PMU cmdline match" that covers PMU name
wildcard support provided by function perf_pmu__match(). The test works
with a wide range of supported combinations of PMU name matching but
omits the case that if the perf_pmu__match() cannot match the PMU name
to the wildcard, it tries to match its alias. However, this variable is
not set up, causing the test case to fail when run with subprocesses or
to segfault if run as a single process.

exactly the same as the matching of the PMU name.

65444581a4 drm/amd/display: Determine IPS mode by ASIC and PMFW versions
[Why]

DCN IPS interoperates with other system idle power features, such as
Zstates.

On DCN35, there is a known issue where system Z8 + DCN IPS2 causes a
hard hang. We observe this on systems where the SBIOS allows Z8.

Though there is a SBIOS fix, there's no guarantee that users will get it
any time soon, or even install it. A workaround is needed to prevent
this from rearing its head in the wild.

[How]

For DCN35, check the pmfw version to determine whether the SBIOS has the
fix. If not, set IPS1+RCG as the deepest possible state in all cases
except for s0ix and display off (DPMS). Otherwise, enable all IPS

3297d047cd iommu/vt-d: Refactor IOTLB and Dev-IOTLB flush for batching
Extracts IOTLB and Dev-IOTLB invalidation logic from cache tag flush
interfaces into dedicated helper functions. It prepares the codebase
for upcoming changes to support batched cache invalidations.

To enable direct use of qi_flush helpers in the new functions,
iommu->flush.flush_iotlb and quirk_extra_dev_tlb_flush() are opened up.

No functional changes are intended.

f701c9f36b iommu/vt-d: Factor out invalidation descriptor composition
Separate the logic for constructing IOTLB and device TLB invalidation
descriptors from the qi_flush interfaces. New helpers, qi_desc(), are
introduced to encapsulate this common functionality.

Moving descriptor composition code to new helpers enables its reuse in
the upcoming qi_batch interfaces.

No functional changes are intended.

1f5e307ca1 iommu/vt-d: Unconditionally flush device TLB for pasid table updates
The caching mode of an IOMMU is irrelevant to the behavior of the device
TLB. Previously, commit <304b3bde24> ("iommu/vt-d: Remove caching mode
check before device TLB flush") removed this redundant check in the
domain unmap path.

Checking the caching mode before flushing the device TLB after a pasid
table entry is updated is unnecessary and can lead to inconsistent
behavior.

Extends this consistency by removing the caching mode check in the pasid
table update path.
