[PATCH v1 0/3] Tegra DRM: Support memory bandwidth management for display

From: Dmitry Osipenko
Date: Sun May 05 2019 - 13:40:27 EST


Hello,

Display controllers have a need for minimum memory bandwidth in order to
maintain data-stream to output at a required rate. There is a visual
corruption once the requirement is violated and CRTC reset may be required
in order to recover. This series adds preliminary support for the memory
bandwidth management, it will become active once Memory Controller drivers
will get support for the PM memory bandwidth QoS.

Dmitry Osipenko (3):
drm/tegra: dc: Tune up high priority request controls on Tegra20
drm/tegra: dc: Extend debug stats with total number of events
drm/tegra: Support PM QoS memory bandwidth management
