2023-12-06drm/amd/display: Change dither policy for 10bpc to roundKrunoslav Kovac
We use spatial dither by default for all output bpc (6/8/10). While it makes some sense for FP16, for ARGB2101010 surfaces it makes little sense as even if we skip color pipeline to preserve bit accuracy, spatial dither adds random noise so a few percent pixels are 1 bit off. This commit chages the 10bpc out dither policy to rounding. Also, in Polaris/Vega times, policy used to be round for 10bpc out; it looks like it got inadvertently changed for Navi.

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/fixes Arm FF-A fixes for v6.7 A bunch of fixes addressing issues around the notification support that was added this cycle. They address issue in partition IDs handling in ffa_notification_info_get(), notifications cleanup path and the size of the allocation in ffa_partitions_cleanup(). It also adds check for the notification enabled state so that the drivers registering the callbacks can be rejected if not enabled/supported. It also moves the partitions setup operation after the notification initialisation so that the driver has the correct state for notification enabled/supported before the partitions are initialised/setup. It also now allows FF-A initialisation to complete successfully even when the notification initialisation fails as it is an optional support in the specification. Initial support just allowed it only if the firmware didn't support notifications. Finally, it also adds a fix for smatch warning by declaring ffa_bus_type structure in the header. * tag 'ffa-fixes-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_ffa: Fix ffa_notification_info_get() IDs handling firmware: arm_ffa: Fix the size of the allocation in ffa_partitions_cleanup() firmware: arm_ffa: Fix FFA notifications cleanup path firmware: arm_ffa: Add checks for the notification enabled state firmware: arm_ffa: Setup the partitions after the notification initialisation firmware: arm_ffa: Allow FF-A initialisation even when notification fails firmware: arm_ffa: Declare ffa_bus_type structure in the header Link: https://lore.kernel.org/r/20231116191603.929767-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2023-12-06drm/bridge: nxp-ptn3460: simplify some error checkingDan Carpenter
The i2c_master_send/recv() functions return negative error codes or they return "len" on success. So the error handling here can be written as just normal checks for "if (ret < 0) return ret;". No need to complicate things. Btw, in this code the "len" parameter can never be zero, but even if it were, then I feel like this would still be the best way to write it.

2023-12-06drm/atomic-helpers: Invoke end_fb_access while owning plane stateThomas Zimmermann
Invoke drm_plane_helper_funcs.end_fb_access before drm_atomic_helper_commit_hw_done(). The latter function hands over ownership of the plane state to the following commit, which might free it. Releasing resources in end_fb_access then operates on undefined state. This bug has been observed with non-blocking commits when they are being queued up quickly. Here is an example stack trace from the bug report. The plane state has been free'd already, so the pages for drm_gem_fb_vunmap() are gone. Unable to handle kernel paging request at virtual address 0000000100000049 [...] drm_gem_fb_vunmap+0x18/0x74 drm_gem_end_shadow_fb_access+0x1c/0x2c drm_atomic_helper_cleanup_planes+0x58/0xd8 drm_atomic_helper_commit_tail+0x90/0xa0 commit_tail+0x15c/0x188 commit_work+0x14/0x20 Fix this by running end_fb_access immediately after updating all planes in drm_atomic_helper_commit_planes(). The existing clean-up helper drm_atomic_helper_cleanup_planes() now only handles cleanup_fb. For aborted commits, roll back from drm_atomic_helper_prepare_planes() in the new helper drm_atomic_helper_unprepare_planes(). This case is different from regular cleanup, as we have to release the new state; regular cleanup releases the old state. The new helper also invokes cleanup_fb for all planes. The changes mostly involve DRM's atomic helpers. Only two drivers, i915 and nouveau, implement their own commit function. Update them to invoke drm_atomic_helper_unprepare_planes(). Drivers with custom commit_tail function do not require changes. v4: * fix documentation (kernel test robot) v3: * add drm_atomic_helper_unprepare_planes() for rolling back * use correct state for end_fb_access v2: * fix test in drm_atomic_helper_cleanup_planes() Reported-by: Alyssa Ross <hi@alyssa.is> Closes: https://lore.kernel.org/dri-devel/87leazm0ya.fsf@alyssa.is/ Suggested-by: Daniel Vetter <daniel@ffwll.ch> Fixes: 94d879eaf7fb ("drm/atomic-helper: Add {begin,end}_fb_access to plane helpers") Tested-by: Alyssa Ross <hi@alyssa.is> Reviewed-by: Alyssa Ross <hi@alyssa.is> Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Cc: <stable@vger.kernel.org> # v6.2+ Link: https://patchwork.freedesktop.org/patch/msgid/20231204083247.22006-1-tzimmermann@suse.de
