This file was split in commit 5d945cbcd4b16a29d6470a80dfb19738f9a4319f
("drm/amd/display: Create a file dedicated to planes") the logic in
dm_plane_format_mod_supported() function got changed by a switch logic.
That change broke drm_plane modifiers setting on series 5000 APUs
(tested on OXP mini AMD 5800U and HP Dev One 5850U PRO)
leading to Gamescope not working as reproted on GitHub[1]

To reproduce the issue, enter a TTY and run:

$ gamescope -- vkcube

With said commit applied it will abort. This one restores the old logic,
fixing the issue that affects Gamescope.

Hi,

First of all, thanks a lot for this patch.

You can drop asic_id since it is not used anymore.

Thanks

Hi,

First of all, thanks a lot for this patch.

You can drop asic_id since it is not used anymore.

Thanks

This file was split in commit 5d945cbcd4b16a29d6470a80dfb19738f9a4319f
("drm/amd/display: Create a file dedicated to planes") and the logic in
dm_plane_format_mod_supported() function got changed by a switch logic.
That change broke drm_plane modifiers setting on series 5000 APUs
(tested on OXP mini AMD 5800U and HP Dev One 5850U PRO)
leading to Gamescope not working as reported on GitHub[1]

To reproduce the issue, enter a TTY and run:

$ gamescope -- vkcube

With said commit applied it will abort. This one restores the old logic,
fixing the issue that affects Gamescope.

This file was split in commit 5d945cbcd4b16a29d6470a80dfb19738f9a4319f
("drm/amd/display: Create a file dedicated to planes") and the logic in
dm_plane_format_mod_supported() function got changed by a switch logic.
That change broke drm_plane modifiers setting on series 5000 APUs
(tested on OXP mini AMD 5800U and HP Dev One 5850U PRO)
leading to Gamescope not working as reported on GitHub[1]

To reproduce the issue, enter a TTY and run:

$ gamescope -- vkcube

With said commit applied it will abort. This one restores the old logic,
fixing the issue that affects Gamescope.

* [PATCH v2] drm/amd/display: Revert logic for plane modifiers

This file was split in commit 5d945cbcd4b16a29d6470a80dfb19738f9a4319f
("drm/amd/display: Create a file dedicated to planes") and the logic in
dm_plane_format_mod_supported() function got changed by a switch logic.
That change broke drm_plane modifiers setting on series 5000 APUs
(tested on OXP mini AMD 5800U and HP Dev One 5850U PRO)
leading to Gamescope not working as reported on GitHub[1]

To reproduce the issue, enter a TTY and run:

$ gamescope -- vkcube

With said commit applied it will abort. This one restores the old logic,
fixing the issue that affects Gamescope.
