drm/msm/dpu: program correct register for UBWC config on DPU 8.x+
drm/msm/dpu: fix SSPP_UBWC_STATIC_CTRL programming on UBWC 5.x+
Thanks, seems to fix the
https://gitlab.freedesktop.org/drm/msm/-/issues/79 issue for me:
- disabled the workaround (`debug { disable-direct-scanout }` in Niri's
config) i.e. enabled direct scanout
- opened System Shock Remake in full screen on the external 3840x2560@60
monitor
- everything looks fine, the right half of the screen does not show any
alpha artifacts
