[PATCH v3 03/17] drm/i915/dp: Add compute routine for DP HDR Metadata Infoframe SDP

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



It stores computed dp hdr metadata infoframe sdp to infoframes.drm of
crtc state. It referenced intel_hdmi_compute_drm_infoframe().

While computing, we'll also fill out the inforames.enable bitmask
appropriately.

v2: Wrap a long line.
