177e876af8 drm/i915/perf: Configure OAR for specific context
Gen12 supports saving/restoring render counters per context. Apply OAR
configuration only for the context that is passed in to perf.

v2:
- Fix OACTXCONTROL value to only stop/resume counters.
- Remove gen12_update_reg_state_unlocked as power state is already
  applied by the caller.

v3: (Lionel)
- Move register initialization into the array
- Assume a valid oa_config in enable_metric_set

2a264a0fd4 drm/i915/perf: Allow non-privileged access when OA buffer is not sampled
SAMPLE_OA_REPORT enables sampling of OA reports from the OA buffer.
Since reports from OA buffer had system wide visibility, collecting
samples from the OA buffer was a privileged operation on previous
platforms. Prior to TGL, it was also necessary to sample the OA buffer
to normalize reports from MI REPORT PERF COUNT.

TGL has a dedicated OAR unit to sample perf reports for a specific
render context. This removes the necessity to sample OA buffer.

- If not sampling the OA buffer, allow non-privileged access. An earlier
  patch allows the non-privilege access:
  https://patchwork.freedesktop.org/patch/337716/?series=68582&rev=1
- Clear up the path for non-privileged access in this patch

78baee8d3b MAINTAINERS: Match on dma_buf|fence|resv anywhere
I've spent a bit too much time reviewing all kinds of users all over
the kernel for this buffer sharing infrastructure. And some of it is
at least questionable.

Make sure we at least see when this stuff flies by.

cc90bc6842 block: fix "check bi_size overflow before merge"
This partially reverts commit e3a5d8e386.

Commit e3a5d8e386 ("check bi_size overflow before merge") adds a bio_full
check to __bio_try_merge_page.  This will cause __bio_try_merge_page to fail
when the last bi_io_vec has been reached.  Instead, what we want here is only
the bi_size overflow check.

b9ea0bae26 ACPI: PM: Avoid attaching ACPI PM domain to certain devices
Certain ACPI-enumerated devices represented as platform devices in
Linux, like fans, require special low-level power management handling
implemented by their drivers that is not in agreement with the ACPI
PM domain behavior.  That leads to problems with managing ACPI fans
during system-wide suspend and resume.

For this reason, make acpi_dev_pm_attach() skip the affected devices
by adding a list of device IDs to avoid to it and putting the IDs of
the affected devices into that list.

9bd0160d12 afs: Fix afs_find_server lookups for ipv4 peers
afs_find_server tries to find a server that has an address that
matches the transport address of an rxrpc peer.  The code assumes
that the transport address is always ipv6, with ipv4 represented
as ipv4 mapped addresses, but that's not the case.  If the transport
family is AF_INET, srx->transport.sin6.sin6_addr.s6_addr32[] will
be beyond the actual ipv4 address and will always be 0, and all
ipv4 addresses will be seen as matching.

As a result, the first ipv4 address seen on any server will be
considered a match, and the server returned may be the wrong one.

One of the consequences is that callbacks received over ipv4 will
only be correctly applied for the server that happens to have the
first ipv4 address on the fs_addresses4 list.  Callbacks over ipv4
from all other servers are dropped, causing the client to serve stale
data.

This is fixed by looking at the transport family, and comparing ipv4
addresses based on a sockaddr_in structure rather than a sockaddr_in6.

available sleep state to the last available sleep state (which should
be longer).

Detailed description for this pull request:
 1. Update devfreq core
 - Add PM QoS support for devfreq device with following QoS type. External user
 of devfreq device can request the minimum and maximum frequency according to
 their multiple requirements.
 : DEV_PM_QOS_MIN_FREQUENCY is used for requesting the minimum device frequency.
 : DEV_PM_QOS_MAX_FREQUENCY is used for requesting the maximum device frequency.
 
 - Use PM QoS interface when entering the min/max_freq via sysfs interface.
 
 - Add get_freq_range() helper function in order to get the final min/max
 frequency among the multiple requirements of min/max frequency.
 
 - Fix the issue such as fixing the return value and modify code
 for more correct exception handling if error happen.

43cb86799f drm: meson: venc: cvbs: fix CVBS mode matching
With commit 222ec1618c ("drm: Add aspect ratio parsing in DRM
layer") the drm core started honoring the picture_aspect_ratio field
when comparing two drm_display_modes. Prior to that it was ignored.
When the CVBS encoder driver was initially submitted there was no aspect
ratio check.

Switch from drm_mode_equal() to drm_mode_match() without
DRM_MODE_MATCH_ASPECT_RATIO to fix "kmscube" and X.org output using the
CVBS connector. When (for example) kmscube sets the output mode when
using the CVBS connector it passes HDMI_PICTURE_ASPECT_NONE, making the
drm_mode_equal() fail as it include the aspect ratio.

Prior to this patch kmscube reported:
  failed to set mode: Invalid argument

The CVBS mode checking in the sun4i (drivers/gpu/drm/sun4i/sun4i_tv.c
sun4i_tv_mode_to_drm_mode) and ZTE (drivers/gpu/drm/zte/zx_tvenc.c
tvenc_mode_{pal,ntsc}) drivers don't set the "picture_aspect_ratio" at
all. The Meson VPU driver does not rely on the aspect ratio for the CVBS
output so we can safely decouple it from the hdmi_picture_aspect
setting.

27dbc542f6 PM / devfreq: Use PM QoS for sysfs min/max_freq
Switch the handling of min_freq and max_freq from sysfs to use the
dev_pm_qos_request interface.

Since PM QoS handles frequencies as kHz this change reduces the
precision of min_freq and max_freq. This shouldn't introduce problems
because frequencies which are not an integer number of kHz are likely
not an integer number of Hz either.

Try to ensure compatibility by rounding min values down and rounding
max values up.

42a6b25e67 PM / devfreq: Don't fail devfreq_dev_release if not in list
Right now devfreq_dev_release will print a warning and abort the rest of
the cleanup if the devfreq instance is not part of the global
devfreq_list. But this is a valid scenario, for example it can happen if
the governor can't be found or on any other init error that happens
after device_register.

Initialize devfreq->node to an empty list head in devfreq_add_device so
that list_del becomes a safe noop inside devfreq_dev_release and we can
continue the rest of the cleanup.

46cecc0bf0 PM / devfreq: Introduce get_freq_range helper
Moving handling of min/max freq to a single function and call it from
update_devfreq and for printing min/max freq values in sysfs.

This changes the behavior of out-of-range min_freq/max_freq: clamping
is now done at evaluation time. This means that if an out-of-range
constraint is imposed by sysfs and it later becomes valid then it will
be enforced.

The devfreq_notifier_call functions will update scaling_min_freq and

If fetching the maximum frequency fails then scaling_max_freq remains
set to zero which is confusing. Set to ULONG_MAX instead so we don't

316933cf74 orangefs: posix open permission checking...
Orangefs has no open, and orangefs checks file permissions
 on each file access. Posix requires that file permissions
 be checked on open and nowhere else. Orangefs-through-the-kernel
 needs to seem posix compliant.
 
 The VFS opens files, even if the filesystem provides no
 method. We can see if a file was successfully opened for
 read and or for write by looking at file->f_mode.
 
 When writes are flowing from the page cache, file is no
 longer available. We can trust the VFS to have checked
 file->f_mode before writing to the page cache.
 
 The mode of a file might change between when it is opened
 and IO commences, or it might be created with an arbitrary mode.
 
 We'll make sure we don't hit EACCES during the IO stage by
 using UID 0.

911d137ab0 This is a relatively quiet cycle for nfsd, mainly various bugfixes.
Possibly most interesting is Trond's fixes for some callback races that
 were due to my incomplete understanding of rpc client shutdown.
 Unfortunately at the last minute I've started noticing a new
 intermittent failure to send callbacks.  As the logic seems basically
 correct, I'm leaving Trond's patches in for now, and hope to find a fix
 in the next week so I don't have to revert those patches.
