Chris Wilson 36dbc4d769 drm/i915/fbc: FBC causes display flicker when VT-d is enabled on Skylake ... Erratum SKL075: Display Flicker May Occur When Both VT-d And FBC Are Enabled "Display flickering may occur when both FBC (Frame Buffer Compression) and VT - d (Intel® Virtualization Technology for Directed I/O) are enabled and in use by the display controller." Ville found the w/a name in the database: WaFbcTurnOffFbcWhenHyperVisorIsUsed:skl,bxt and also dug out that it affects Broxton. v2: Log when the quirk is applied. v3: Ensure i915.enable_fbc is false when !HAS_FBC() v4: Fix function name after rebase v5: Add Broxton to the workaround Note for backporting to stable, we need to add #define mkwrite_device_info(ptr) \ ((struct intel_device_info *)INTEL_INFO(ptr)) Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: stable@vger.kernel.org Link: http://patchwork.freedesktop.org/patch/msgid/1470296633-20388-1-git-send-email-chris@chris-wilson.co.uk		2016-08-04 10:28:05 +01:00
