From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> Avoid the shrinker evicting the DPT during hibernate and causing an oops. This might also fix DPT induced display faults during high memory pressure (though still don't have a real theory how that could actually happen). Also add a i915.enable_dpt modparam to disable DPT usage via the chicken bit. This can be useful when trying to debug suspected DPT issues. Ville Syrjälä (6): drm/i915/dpt: Treat the DPT BO as a framebuffer drm/i915/dpt: Only do the POT stride remap when using DPT drm/i915/dpt: Introduce HAS_DPT() drm/i915: Add PLANE_CHICKEN registers drm/i915/dpt: Add a modparam to disable DPT via the chicken bit drm/i915: Move PLANE_BUG_CFG bit definitons to the correct place drivers/gpu/drm/i915/display/intel_display.c | 6 +++++ drivers/gpu/drm/i915/display/intel_dpt.c | 23 +++++++++++++++++++ drivers/gpu/drm/i915/display/intel_dpt.h | 2 ++ drivers/gpu/drm/i915/display/intel_fb.c | 11 +++++---- drivers/gpu/drm/i915/display/intel_fb.h | 1 + .../drm/i915/display/skl_universal_plane.c | 6 +++++ drivers/gpu/drm/i915/gem/i915_gem_object.h | 2 +- .../gpu/drm/i915/gem/i915_gem_object_types.h | 3 +++ drivers/gpu/drm/i915/i915_drv.h | 2 ++ drivers/gpu/drm/i915/i915_params.c | 3 +++ drivers/gpu/drm/i915/i915_params.h | 1 + drivers/gpu/drm/i915/i915_reg.h | 21 +++++++++++++---- 12 files changed, 70 insertions(+), 11 deletions(-) -- 2.39.2
