[ Upstream commit 631420b06597a33c72b6dcef78d1c2dea17f452d ]
The point of the WARN was to print something, not oops
straight up. Currently that is precisely what happens
if we can't find the connector for the crtc in the atomic
state. Get the dev pointer from the atomic state instead
of the potentially NULL encoder to avoid that.

When hitting an error, the error path forgot to unmap dma mappings and
could call set_pages_wb() on already uncached pages.
Fix this by introducing a common ttm_pool_free_range() function that

To avoid preventing the display from coming up before the rootfs is
mounted, without resorting to packing fw in the initrd, the GPU has
this limbo state where the device is probed, but we aren't ready to
start sending commands to it. This is particularly problematic for
a6xx, since the GMU (which requires fw to be loaded) is the one that
is controlling the power/clk/icc votes.
So defer enabling runpm until we are ready to call gpu->hw_init(),
as that is a point where we know we have all the needed fw and are
ready to start sending commands to the coproc's.

When dynamically switching lanes was removed, the intent of the code
was to check to make sure that higher speed items used 4 lanes, but
it had the unintended consequence of removing the slower speeds for

This attempts to remedy this by doing a check to see that the
max frequency doesn't exceed the chip limit, and a second
check to make sure that the max bit-rate doesn't exceed the
number of lanes * max bit rate / lane.

drm_kms_helper_poll_enable for 10s in future. Later we try to replace
that in drm_helper_probe_single_connector_modes with a 0s schedule with

But as there is already a job in the queue this fails, and the immediate
job we wanted with delayed_event set doesn't occur until 10s later.
And that call acts as if connector state has changed, reprobing modes.
This has a side effect of waking up a display that has been blanked.
Make sure we cancel the old job before submitting the immediate one.

On TGL+ the DSS control registers are at different offsets, and there's
one per pipe. Fix the offsets to fix dual link DSI for TGL+.
There would be helpers for this in the DSC code, but just do the quick
fix now for DSI. Long term, we should probably move all the DSS handling
into intel_vdsc.c, so exporting the helpers seems counter-productive.

commit 2b072442f4962231a8516485012bb2d2551ef2fe upstream.
S2idle resume freeze can be observed on Intel ADL + AMD WX5500. This is
caused by commit 0064b0ce85bb ("drm/amd/pm: enable ASPM by default").
The root cause is still not clear for now.
So extend and apply the ASPM quirk from commit e02fe3bc7aba
("drm/amdgpu: vi: disable ASPM on Intel Alder Lake based systems"), to
workaround the issue on Navi cards too.

commit e0e6b416b25ee14716f3549e0cbec1011b193809 upstream.
Users reported oopses on list corruptions when using i915 perf with a
number of concurrently running graphics applications. Root cause analysis
pointed at an issue in barrier processing code -- a race among perf open /
close replacing active barriers with perf requests on kernel context and
concurrent barrier preallocate / acquire operations performed during user
context first pin / last unpin.
When adding a request to a composite tracker, we try to reuse an existing
fence tracker, already allocated and registered with that composite. The
tracker we obtain may already track another fence, may be an idle barrier,
or an active barrier.
If the tracker we get occurs a non-idle barrier then we try to delete that
barrier from a list of barrier tasks it belongs to. However, while doing
that we don't respect return value from a function that performs the
barrier deletion. Should the deletion ever fail, we would end up reusing
the tracker still registered as a barrier task. Since the same structure
field is reused with both fence callback lists and barrier tasks list,
list corruptions would likely occur.
Barriers are now deleted from a barrier tasks list by temporarily removing
the list content, traversing that content with skip over the node to be
deleted, then populating the list back with the modified content. Should
that intentionally racy concurrent deletion attempts be not serialized,
one or more of those may fail because of the list being temporary empty.
Related code that ignores the results of barrier deletion was initially
introduced in v5.4 by commit d8af05ff38ae ("drm/i915: Allow sharing the
idle-barrier from other kernel requests"). However, all users of the
barrier deletion routine were apparently serialized at that time, then the
issue didn't exhibit itself. Results of git bisect with help of a newly
developed igt@gem_barrier_race@remote-request IGT test indicate that list
corruptions might start to appear after commit 311770173fac ("drm/i915/gt:
Schedule request retirement when timeline idles"), introduced in v5.5.
Respect results of barrier deletion attempts -- mark the barrier as idle
only if successfully deleted from the list. Then, before proceeding with
setting our fence as the one currently tracked, make sure that the tracker
we've got is not a non-idle barrier. If that check fails then don't use
that tracker but go back and try to acquire a new, usable one.
v3: use unlikely() to document what outcome we expect (Andi),
- fix bad grammar in commit description.
v2: no code changes,
- blame commit 311770173fac ("drm/i915/gt: Schedule request retirement
when timeline idles"), v5.5, not commit d8af05ff38ae ("drm/i915: Allow

Always setup overdrive tables after resume. Preserve only some

Copy restored user_overdrive_table into od_table to get correct

On cold boot, BTC was triggered and GfxVfCurve was calibrated. We
got VfCurve settings (a). On resuming back, BTC will be triggered
again and GfxVfCurve will be recalibrated. VfCurve settings (b)
got may be different from those of cold boot. So if we reuse
those VfCurve settings (a) got on cold boot on suspend, we can
run into discrepencies.

PSR2 selective is not supported over rotated and scaled planes.
We had the rotation check in intel_psr2_sel_fetch_config_valid()
but that code path is only execute when a modeset is needed and
those plane parameters can change without a modeset.
Pipe selective fetch restrictions are also needed, it could be added
in intel_psr_compute_config() but pippe scaling is computed after
it is executed, so leaving as is for now.
There is no much loss in this approach as it would cause selective
fetch to not enabled as for alderlake-P and newer will cause it to
switch to PSR1 that will have the same power-savings as do full pipe
fetch.
Also need to check those restricions in the second
for_each_oldnew_intel_plane_in_state() loop because the state could
only have a plane that is not affected by those restricitons but
the damaged area intersect with planes that has those restrictions,
so a full pipe fetch is required.

drm_atomic_helper_damage_iter_init() + drm_atomic_for_each_plane_damage()
returns the full plane area in case no damaged area was set by
userspace or it was discarted by driver.
This is important to fix the rendering of userspace applications that
does frontbuffer rendering and notify driver about dirty areas but do
not set any dirty clips.
With this we don't need to worry about to check and mark the whole
area as damaged in page flips.
Another important change here is the move of
drm_atomic_add_affected_planes() call, it needs to called late
otherwise the area of all the planes would be added to pipe_clip and
not saving power.
