fbceb39b536e40c2f7cc47ab42037bb7c2b7ced9 - drm/i915/psr: Add defininitions for INTEL_WA_REGISTER_CAPS DPCD register

Fri, 15 May 2026 11:57:53 +0200

drm/i915/psr: Add defininitions for INTEL_WA_REGISTER_CAPS DPCD registerEDP specification says:"If either VSC SDP is unable to be transmitted 100 ns before the SU region,the Source device may optionally transmit the VSC SDP during the priorvideo scan line’s HBlank period There is a Intel specific drm dp registercurrently containing bits related how TCON can support PSR2 with SDP onprior line."Unfortunately many panels are having problems in implementing this. Sothere is a custom Intel specific DPCD register (INTEL_WA_REGISTER_CAPS) tofigure out if this is properly implemented on a panel or if panel doesn'trequire that 100 ns delay before the SU region. Here are the definitions inthis custom DPCD address:0 = Panel doesn't support SDP on prior line1 = Panel supports SDP on prior line2 = Panel doesn't have 100ns requirement3 = ReservedAdd definitions for this new register and it's values into new headerintel_dpcd.h.v2: add INTEL_DPCD_ prefix to definitionsBspec: 74741Signed-off-by: Jouni Högander Reviewed-by: Suraj Kandpal Link: https://patch.msgid.link/20260515095756.2799483-2-jouni.hogander@intel.com(cherry picked from commit 1da1c9294825f08f622c473480d185680c2a3b75)Signed-off-by: Tvrtko Ursulin List of files: /linux/drivers/gpu/drm/i915/display/intel_dpcd.h
