[Intel-gfx] [PATCH v4 5/5] drm/i915/psr/bdw+: Enable CRC check in the static frame on the sink side

2018-06-14 Thread José Roberto de Souza
Sink can be configured to calculate the CRC over the static frame and compare with the CRC calculated and transmited in the VSC SDP by source, if there is a mismatch sink will do a short pulse in HPD and set DP_PSR_LINK_CRC_ERROR in DP_PSR_ERROR_STATUS. Spec: 7723 v4: patch moved to after
