2023-10-09drm/amd/display: Update stream maskDuncan Ma
[Why] Whenever stream changes because of new pipe arrangements such as ODM. The new stream mask is not reflected in DMCUB. The mismatch in stream mask is blocking ips entry in some scenarios.

Surfaces can be backed (i.e. stored in) memory objects (mob's) which are created and managed by the userspace as GEM buffers.

2023-10-09drm/vmwgfx: fix typo of sizeof argumentKonstantin Meskhidze
Since size of 'header' pointer and '*header' structure is equal on 64-bit machines issue probably didn't cause any wrong behavior. But anyway, fixing typo is required. Fixes: 7a73ba7469cb ("drm/vmwgfx: Use TTM handles instead of SIDs as user-space surface handles.")

2023-10-09drm/rockchip: remove redundant of_match_ptrZhu Wang
The driver depends on CONFIG_OF, so it is not necessary to use of_match_ptr here. Even for drivers that do not depend on CONFIG_OF, it's almost always better to leave out the of_match_ptr(), since the only thing it can possibly do is to save a few bytes of .text if a driver can be used both with and without it. Hence we remove of_match_ptr.

cdn_dp_audio_codec_init() can fail. So add some error handling. If component_add() fails, the previous cdn_dp_audio_codec_init() call should be undone, as already done in the remove function.

2023-10-09drm/rockchip: vop2: Convert to use maple tree register cacheMark Brown
The maple tree register cache is based on a much more modern data structure than the rbtree cache and makes optimisation choices which are probably more appropriate for modern systems than those made by the rbtree cache.

2023-10-09drm/rockchip: vop2: Demote message in mod_supported to drm_dbg_kmsMichael Tretter
Checking if a modifier is supported by a plane is normal behavior. It is normal that a plane may not support certain modifiers. Failing the check doesn't justify an error message in the kernel log and may mislead users. Demote the error message to drm_dbg_kms to only print the message if the respective debug messages are enabled. This is similar to the behavior in rockchip_drm_vop.c.

2023-10-09drm/msm: carve out KMS code from msm_drv.cDmitry Baryshkov
The msm_drv.c contains generic code intermixed with KMS handling code. Move all KMS-related code to a separate msm_kms.c file, cleaning up init code while doing this move. This also prevents msm driver from registering modesetting / atomic interfaces in the headless case.
