Subject: [Intel-gfx] [RFC][PATCH 0/3] Infoframe changes for DP-HDMI2.1 PCON
Date: Fri, 18 Dec 2020 16:03:34 +0530 [thread overview]
Message-ID: <20201218103337.31068-1-swati2.sharma@intel.com> (raw)
These patches should be applied on top of series
https://patchwork.freedesktop.org/series/82098/
(Add support for DP-HDMI2.1 PCON)
This is good to have feature, even if we don't send any AVI info frame,
PCON is able to create and send it based on DP VSC packets. However,
it gives better control with source sending the infoframe by itself.
TODO:
Need to fix:
[ 8.906566] i915 0000:00:02.0: [drm] *ERROR* [CRTC:98:pipe A] mismatch in has_infoframe (expected yes, found no)
[ 8.916828] i915 0000:00:02.0: [drm] *ERROR* [CRTC:98:pipe A] mismatch in infoframes.enable (expected 0x0000000a, found 0x00000002)
Swati Sharma (3):
drm/i915: Export intel_hdmi_compute_avi_infoframe()
drm/i915: Sending AVI infoframe through GMP DIP
drm/i915: Implement readout for AVI infoframe SDP
