Improving the Linux Display Stack Reliability
summary
Proposes a compact KMS test tool: a rust static binary (~4 MB) that runs on-device, displays test frames embedding a frame header with counter+hash, and validates output via a cheap HDMI-to-CSI bridge + capture board (prototype on Raspberry Pi). Demonstrates catching real bugs (HDMI scrambling, hotplug/HPD interactions) and passes 1080p at 60 Hz; remaining limits: requires interrupt hotplug, cannot verify color-space transforms, 4K capture hardware is rare.
