Rodrigo Vivi 0cc4b69960 drm/i915: Mask LPSP to get PSR working even with Power Well in use by audio. ... Power Well in use forces constantly PSR to exit. On recent Kernel I noticed that PSR Performance Counter was always 0 indicating that PSR was never really achieved. By masking LPSP, PSR can work normally and save power on Haswell. Two bugs had been raised with PSR flag enabled: - "Screen flickers when booted by enabling PSR in the kernel (i915.enable_psr=1) , the system is booting to a gray screen." - "When booting the DUT with PSR feature enabled in the kernel (i915.enable_psr=1) , the system is booting to a gray screen." Both bugs has been fixed by this patch. v2: proper comment for -fixes Tested-by: Selvaraj, Elavarasan <elavarasanx.selvaraj@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@gmail.com> Cc: stable@vger.kernel.org Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>		2013-10-03 20:07:17 +02:00
