      drm/i915/gt: Convert PSS_MODE2 to multicast register · 41badc01
      Gustavo Sousa authored 
      That register became a multicast register as of Xe_HP and it is
currently used only for DG2. Use a proper prefix since there could be
usage of the same register for previous platforms in the future, which
would require a different definition (i.e. using _MMIO).

Note that, in its current state, the code does not cause functional
problems, since the actual application of the workaround would
implicitly use multicast mode. This fix is more toward consistency and
being future-proof uses of this register outside of workarounds.

v2:
  - Add paragraph noting that this change is for consistency and
    making the code future-proof. (Matt)

      drm/vkms: reintroduce prepare_fb and cleanup_fb functions · 6e41acd2
      Maíra Canal authored 
      With commit 359c6649 ("drm/gem: Implement shadow-plane {begin,
end}_fb_access with vmap"), the behavior of the shadow-plane helpers
changed and the vunmap is now performed at the end of
the current pageflip, instead of the end of the following pageflip.

By performing the vunmap at the end of the current pageflip, invalid
memory is accessed by the vkms during the plane composition, as the data
is being unmapped before being used, as reported by the following
warning:

      Since the DP/HDMI connector do not set connector->doublescan_allowed,
the doublescan modes will get automatically filtered during
drm_helper_probe_single_connector_modes().

Therefore check for double scan modes is not required and is dropped
from modevalid functions for both DP and HDMI.
