Subject: [PATCH 0/4] DRM helpers for Display Stream Compression PPS infoframes
Date: Wed, 9 May 2018 14:58:23 -0700 [thread overview]
Message-ID: <1525903103-19119-1-git-send-email-manasi.d.navare@intel.com> (raw)
VESA Display Stream Compression is a specification for visually losless
video compression over display links. The DSC standard also defines
a picture parameter set (PPS) which encoder must communicate to decoders.
This is done by encapsulating PPS header and payload bytes in an infoframe
that can be sent to the display sink using secondary data packets
as defined in DP 1.4 spec.
This patch series creates a new files drm_dsc.h and drm_dsc.c
which define all the DSC related structures and helpers that
can be called by drivers to form DSC PPS infoframes before
enabling Display Stream compression on eDP/DP/MIPI
These files can be used to add more DSC spec related helpers
common to all drivers.
