The VOP2 unit is found on Rockchip SoCs beginning with rk3566/rk3568. It replaces the VOP unit found in the older Rockchip SoCs.
This driver has been derived from the downstream Rockchip Kernel and heavily modified:
- All nonstandard DRM properties have been removed
- dropped struct vop2_plane_state and pass around less data between functions
- Dropped all DRM_FORMAT_* not known on upstream
- rework register access to get rid of excessively used macros
- Drop all waiting for framesyncs
The driver is tested with HDMI and MIPI-DSI display on a RK3568-EVB board. Overlay support is tested with the modetest utility. AFBC support on the cluster windows is tested with weston-simple-dmabuf-egl on weston using the (yet to be upstreamed) panfrost driver support.
When run a weston 10.0.0:
# export XDG_RUNTIME_DIR=/tmp # weston --backend=drm-backend.so --use-pixma --tty=2 --continue=without-input
I got the following error:
drm_atomic_check_only [PLANE:31:Smart0-win0] CRTC set but no FB
Can you please start Weston with --logger-scopes=log,drm-backend and attach the output?
Cheers, Daniel
