It was reported that Weston stops at an assert, which checks that the
page flip event timestamp is the same or newer than the previous
timestamp:
weston_output_finish_frame: Assertion `timespec_sub_to_nsec(stamp, &output->frame_time) >= 0' failed.
With manual tests, I can see that when I enable the CRTC, I get a page
flip event with a timestamp of 0. Tracking this down led to
drm_reset_vblank_timestamp() which does "t_vblank = 0" if
"high-precision query" is not available.
TI DSS does not have any hardware timestamping, and thus the default
ktime_get() is used in the DRM framework to get the vblank timestamp,
and ktime_get() is not "high precision" here.
It is not quite clear why the framework behaves this way, but I assume
the idea is that drm_crtc_vblank_on(), which calls
drm_reset_vblank_timestamp(), can be called at any time, and thus
ktime_get() wouldn't give a good timestamp. And, the idea is that the
driver would wait until next vblank after the CRTC enable, and then we
could get a good timestamp. This is hinted in the comment: "reinitialize
delayed at next vblank interrupt and assign 0 for now".
I think that makes sense. However, when we enable the CRTC in TI DSS,
i.e. we write the enable bit to the hardware, that's the exact moment
when the "vblank cycle" starts. It is the zero point in the cycle, and
thus ktime_get() would give a good timestamp.
I am not sure if this is applicable to other hardware, and if so, how
should it be solved in the framework. So, let's fix this in the tidss
driver at least for now.
This patch updates the vblank->time manually to ktime_get() just before
sending the vblank event, and we enable the crtc just before calling
ktime_get(). To get even more exact timing, the dispc_vp_enable() is
moved inside the event_lock spinlock.
With this, we get a proper timestamp for the page flip event from
enabling the CRTC, and Weston is happy.

tidss_crtc.c calls dispc_vp_prepare() and dispc_vp_enable() in that
order, next to each other. dispc_vp_prepare() does preparations for
enabling the crtc, by writing some registers, and dispc_vp_enable() does
more preparations. As the last thing, dispc_vp_enable() enables the CRTC
by writing the enable bit.
There might have been a reason at some point in the history for this
split, but I can't find any point to it. They also do a bit of
overlapping work: both call dispc_vp_find_bus_fmt(). They could as well
be a single function.
But instead of combining them, this patch moves everything from
dispc_vp_enable() to dispc_vp_prepare(), except the actual CRTC enable
bit write. The reason for this is that unlike all the preparatory
register writes, CRTC enable has an immediate effect, starting the
timing generator and the CRTC as a whole. Thus it may be important to
time the enable just right (as we do in the next patch).
No functional changes.

The assembled developers agreed at the X.Org Developers Conference 2025
that the hack added for amdgpu in drm_sched_fini() shall be removed. It
shouldn't be needed by amdgpu anymore.
As it's unclear whether all drivers really follow the life time rule of
entities having to be torn down before their scheduler, it is reasonable
to warn for a while before removing the hack.
Add a warning in drm_sched_fini() that fires if an entity is still

Matthew Wilcox (Oracle) <willy@infradead.org> says:
It's relatively common in filesystems to want to know the end of the
current folio we're looking at. So common in fact that btrfs has its own
helper for that. Lift that helper to filemap and use it everywhere that
I've noticed it could be used. This actually fixes a long-standing bug
in ocfs2 on 32-bit systems with files larger than 2GiB. Presumably this
is not a common configuration, but I've marked it for backport anyway.
The other filesystems are all fine; none of them have a bug, they're
just mildly inefficient. I think this should all go in via Christian's
tree, ideally with acks from the various fs maintainers (cc'd on their
individual patches).

In the future changes we would like to change the flow of the cache handling.
Add ->populate() callback in order to prepare for that.

Commit e0762fd26a ("rtc: cpcap: Fix initial enable_irq/disable_irq
balance") set 'alarm_enabled' prior to calling the function
devm_request_threaded_irq() because this enables the IRQ. However, right
after calling devm_request_threaded_irq(), the driver calls
disable_irq() to disable the IRQ and so now 'alarm_enabled' will be true
but the IRQ is actually disabled. Revert this commit to fix the
'alarm_enabled' state.

Commit 1502fe0e97 ("rtc: tps6586x: Fix initial enable_irq/disable_irq
balance") breaks the wake-up alarm for the tps6586x. After this commit
was added RTC wake ups from suspend stopped working on the Tegra20
Ventana platform.
The problem is that this change set the 'irq_en' variable to true prior
to calling devm_request_threaded_irq() to indicate that the IRQ is
enabled, however, it was over looked that the flag IRQ_NOAUTOEN is
already set meaning that the IRQ is not enabled by default. This
prevents the IRQ from being enabled as expected. Revert this change to
fix this.

There is a hw restriction that we could enable the FBC for FP16
formats only if the pixel normalization block is enabled. Hence
enable the pixel normalizer block with normalzation factor as
1.0 for the supported FP16 formats to get the FBC enabled. Two
existing helper function definitions are moved up to avoid the
forward declarations as part of this patch as well.

Reduce the compat i915_utils.h to only cover the requirements of
MISSING_CASE() in soc/ and the few i915_inject_probe_failure()
instances, instead of including the entire i915_utils.h from i915. This
prevents new users for the utilities from cropping up.
With this, we can remove the xe/display/ext/i915_utils.c altogether.

The remaining utils display needs from i915_utils.h are primarily
MISSING_CASE() and fetch_and_zero(), with a couple of
i915_inject_probe_failure() uses.
To avoid excessive churn, add duplicates of MISSING_CASE() and
fetch_and_zero() to intel_display_utils.h, and switch display to use the
display utils.
As long as there are display files that include i915_drv.h, which
includes i915_utils.h, we'll need #ifndef guards for MISSING_CASE() and
fetch_and_zero() in both utils headers. We can remove them once display
no longer depends on i915_drv.h.
A couple of files in display still need i915_utils.h for
i915_inject_probe_failure(). Annotate this. They will be handled
separately.

Add intel_display_utils.c for display utilities that need more than a
header.
Start off with intel_display_run_as_guest(). The implementation is
intentional duplication of the i915_utils.h i915_run_as_guest(), with
the idea that it's small enough to not matter.

Add i915_jiffies.h and intel_display_jiffies.h for jiffies timeout and
wait helpers, and use them separately from i915 and display. This helps
reduce the display dependency on i915_utils.h.
Long term, both msecs_to_jiffies_timeout() and
wait_remaining_ms_from_jiffies() really belong in core kernel headers,
but for now unblock display refactoring.

When we are picking a zone for gc it might already be in the pipeline
which can lead to us moving the same data twice resulting in in write
amplification and a very unfortunate case where we keep on garbage
collecting the zone we just filled with migrated data stopping all
forward progress.
Fix this by introducing a count of on-going GC operations on a zone, and
skip any zone with ongoing GC when picking a new victim.
