Cover letter [PATCH v2 0/3] Tegra DRM: Support memory bandwidth management for display
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.
Changelog:
v2: The total size of framebuffer is now calculated more accurately for
planar formats, taking into account chroma sub-sampling.
