[ Upstream commit 7cca7c8096e2c8a4149405438329b5035d0744f0 ]

Video captured in 1400x1050 resolution (bytesperline aka stride = 1408
bytes) is invalid. Fix it.

drm/nouveau/disp: power down unused DP links during init

2021-09-03T08:08:15+00:00

[ Upstream commit 6eaa1f3c59a707332e921e32782ffcad49915c5e ]

When booted with multiple displays attached, the EFI GOP driver on (at
least) Ampere, can leave DP links powered up that aren't being used to
display anything.  This confuses our tracking of SOR routing, with the
likely result being a failed modeset and display engine hang.

Fix this by (ab?)using the DisableLT IED script to power-down the link,
restoring HW to a state the driver expects.

drm: Copy drm_wait_vblank to user before returning

2021-09-03T08:08:15+00:00

[ Upstream commit fa0b1ef5f7a694f48e00804a391245f3471aa155 ]

[Why]
Userspace should get back a copy of drm_wait_vblank that's been modified
even when drm_wait_vblank_ioctl returns a failure.

Rationale:
drm_wait_vblank_ioctl modifies the request and expects the user to read
it back. When the type is RELATIVE, it modifies it to ABSOLUTE and updates
the sequence to become current_vblank_count + sequence (which was
RELATIVE), but now it became ABSOLUTE.
drmWaitVBlank (in libdrm) expects this to be the case as it modifies
the request to be Absolute so it expects the sequence to would have been
updated.

The change is in compat_drm_wait_vblank, which is called by
drm_compat_ioctl. This change of copying the data back regardless of the
return number makes it en par with drm_ioctl, which always copies the
data before returning.

[How]
Return from the function after everything has been copied to user.

drm/i915: Fix syncmap memory leak

[ Upstream commit a63bcf08f0efb5348105bb8e0e1e8c6671077753 ]

A small race exists between intel_gt_retire_requests_timeout and
intel_timeline_exit which could result in the syncmap not getting
free'd. Rather than work to hard to seal this race, simply cleanup the
syncmap on fini.

drm/meson: fix colour distortion from HDR set during vendor u-boot

[ Upstream commit bf33677a3c394bb8fddd48d3bbc97adf0262e045 ]

Add support for the OSD1 HDR registers so meson DRM can handle the HDR
properties set by Amlogic u-boot on G12A and newer devices which result
in blue/green/pink colour distortion to display output.

This takes the original patch submissions from Mathias [0] and [1] with
corrections for formatting and the missing description and attribution
needed for merge.

drm: Return -ENOTTY for non-drm ioctls

2021-07-28T11:31:01+00:00

commit 3abab27c322e0f2acf981595aa8040c9164dc9fb upstream.

drm: Return -ENOTTY for non-drm ioctls

Return -ENOTTY from drm_ioctl() when userspace passes in a cmd number
which doesn't relate to the drm subsystem.

Glibc uses the TCGETS ioctl to implement isatty(), and without this
change isatty() returns it incorrectly returns true for drm devices.

To test run this command:
$ if [ -t 0 ]; then echo is a tty; fi < /dev/dri/card0
which shows "is a tty" without this patch.

This may also modify memory which the userspace application is not
expecting.

drm/msm/mdp4: Fix modifier support enabling

commit 35cbb8c91e9cf310277d3dfb4d046df8edf2df33 upstream.

Setting the cap without the modifier list is very confusing to
userspace. Fix that by listing the ones we support explicitly.

Stable backport so that userspace can rely on this working in a
reasonable way, i.e. that the cap set implies IN_FORMATS is available.
