[Intel-gfx] [PATCH 0/2] Prevent (sleeping) wm updates under vblank evasion

[Matt Roper]

Our low-level plane update functions, which get called while we're under vblank
evasion with IRQ's disabled, currently call intel_update_sprite_watermarks
which is a potentially sleeping operation.  This fumble has been present in the
code ever since we added atomic vblank evasion.  We actually do have a
mechanism to flag the need for wm updates and then perform them once evasion is
finished, but our handling of that flag is a bit busted at the moment (i.e.,
currently only being used when a plane gets disabled).  Let's fix that...

Matt Roper (2):
  drm/i915: Drop parameters to intel_update_sprite_watermarks()
  drm/i915: Update sprite watermarks outside vblank evasion
