[PATCH v5 03/18] 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 infoframes.enable bitmask
appropriately.

v2: Wrap a long line.
v4: Use struct drm_device logging macros
v5: Fix typo [Uma]
