The following XDP_DROP test from [1] stalls the interface after
250 packets.
~# xdb-bench drop -m native eth0
This is because new RX requests are never queued. Fix that.
The below XDP_TX test from [1] fails with a warning
[ 499.947381] XDP_WARN: xdp_update_frame_from_buff(line:277): Driver BUG: missing reserved tailroom
~# xdb-bench tx -m native eth0
Fix that by using PAGE_SIZE during xdp_init_buf().
In XDP_REDIRECT case only 1 packet was processed in rx_poll.
Fix it to process up to budget packets.
Fix all XDP error cases to call trace_xdp_exception() and drop the packet
in am65_cpsw_run_xdp().

On HDMI connectors which use drm_bridge_connector and DRM_BRIDGE_OP_HDMI
IGT chokes on the max_bpc property in several kms_properties tests due
to the drm_bridge_connector failing to reset HDMI-related
properties.
Call __drm_atomic_helper_connector_hdmi_reset() if the
drm_bridge_connector has bridge_hdmi.
It is impossible to call this function from HDMI bridges, none of the
bridge callbacks correspond to the drm_connector_funcs::reset().

drm_bridge_connector is a "leaf" driver, belonging to the display
helper, rather than the "CRTC" drm_kms_helper module. Move the driver
to the drm/display and add necessary Kconfig selection clauses.

Kconfig symbols should not declare dependency on DRM_DISPLAY_HELPER.
Move all parts of DRM_DISPLAY_HELPER to an if DRM_DISPLAY_HELPER block.
It is not possible to make those symbols select DRM_DISPLAY_HELPER
because of the link issues when a part of the helper is selected to be
built-in, while other part is selected to be as module. In such a case
the modular part doesn't get built at all, leading to undefined symbols.
The only viable alternative is to split drm_display_helper.ko into
several small modules, each of them having their own dependencies.

The Partner PD Revision field in GET_CONNECTOR_CAPABILITY
data structure was introduced in UCSI v2.1. In
ucsi_check_connector_capability() the version was assumed to
be 2.0, and in ucsi_register_partner() the field is accessed
completely unconditionally.
Fixing the version in ucsi_check_connector_capability(), and
replacing the unconditional pd_revision assignment with a
direct call to ucsi_check_connector_capability() in
ucsi_register_port(). After this the revision is also
checked only if there is a PD contract.

This fix addresses STAR 9001285599, which only affects DWC_usb3 version
3.20a. The timer value for PM_LC_TIMER in DWC_usb3 3.20a for the Link
ECN changes is incorrect. If the PM TIMER ECN is enabled via GUCTL2[19],
the link compliance test (TD7.21) may fail. If the ECN is not enabled
(GUCTL2[19] = 0), the controller will use the old timer value (5us),
which is still acceptable for the link compliance test. Therefore, clear
GUCTL2[19] to pass the USB link compliance test: TD 7.21.

When operating in High-Speed, it is observed that DSTS[USBLNKST] doesn't
update link state immediately after receiving the wakeup interrupt. Since
wakeup event handler calls the resume callbacks, there is a chance that
function drivers can perform an ep queue, which in turn tries to perform
remote wakeup from send_gadget_ep_cmd(STARTXFER). This happens because
DSTS[[21:18] wasn't updated to U0 yet, it's observed that the latency of
DSTS can be in order of milli-seconds. Hence avoid calling gadget_wakeup
during startxfer to prevent unnecessarily issuing remote wakeup to host.

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: 568220fa9657 ("btrfs: zoned: support RAID0/1/10 on top of raid stripe tree")

FYI: I'm carrying this on perf-tools-next.
The previous attempt fixed the build on debian:experimental-x-mipsel,
but when building on a larger set of containers I noticed it broke the
build on some other 32-bit architectures such as:
42 7.87 ubuntu:18.04-x-arm : FAIL gcc version 7.5.0 (Ubuntu/Linaro 7.5.0-3ubuntu1~18.04)
builtin-daemon.c: In function 'cmd_session_list':
builtin-daemon.c:692:16: error: format '%llu' expects argument of type 'long long unsigned int', but argument 4 has type 'long int' [-Werror=format=]
fprintf(out, "%c%" PRIu64,
^~~~~
builtin-daemon.c:694:13:
csv_sep, (curr - daemon->start) / 60);

/usr/arm-linux-gnueabihf/include/inttypes.h:105:34: note: format string is defined here
# define PRIu64 __PRI64_PREFIX "u"
So lets cast that time_t (32-bit/64-bit) to uint64_t to make sure it
builds everywhere.

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.

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
8 1.87 s 1.87 s 233.48 ms spinlock process_one_work+0x1b5
2 1.87 s 1.87 s 933.92 ms spinlock worker_thread+0x1a2
3 1.81 s 1.81 s 603.93 ms spinlock tmigr_update_events+0x13c
2 1.72 s 1.72 s 861.98 ms spinlock tick_do_update_jiffies64+0x25

1 11.61 us 11.61 us 11.61 us 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.
$ sudo perf lock con -ab -Y spinlock sleep 3
contended total wait max wait avg wait type caller

Commit 3e0bf9fde2984469 ("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.

Initialize the PMU alias to null for all tests of perf_pmu__match()

exactly the same as the matching of the PMU name.

The local extent changeset is passed to clear_record_extent_bits() where
it may have some additional memory dynamically allocated for ulist. When
qgroup is disabled, the memory is leaked because in this case the
changeset is not released upon __btrfs_qgroup_release_data() return.
Since the recorded contents of the changeset are not used thereafter, just
don't pass it.

Backlight updates require aux and/or register access. Therefore, driver
needs to disallow IPS beforehand.
So, acquire the dc lock before calling into dc to update backlight - we
should be doing this regardless of IPS. Then, while the lock is held,
disallow IPS before calling into dc, then allow IPS afterwards (if it
was previously allowed).

[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
