[PATCH v5 03/18] drm/i915/dp: Add compute routine for DP HDR Metadata Infoframe SDP
From: Gwan-gyeong Mun <hidden>
Date: 2020-02-09 03:54:12
Also in:
intel-gfx, linux-fbdev
Subsystem:
drm drivers, intel drm display for xe and i915 drivers, intel drm i915 driver (meteor lake, dg2 and older excluding poulsbo, moorestown and derivative), the rest · Maintainers:
David Airlie, Simona Vetter, Jani Nikula, Rodrigo Vivi, Joonas Lahtinen, Tvrtko Ursulin, Linus Torvalds
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] Signed-off-by: Gwan-gyeong Mun <redacted> Reviewed-by: Uma Shankar <redacted> --- drivers/gpu/drm/i915/display/intel_dp.c | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+)
