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:
I used weston 9.0.90 during testing. I'll try to reproduce the issue with weston 10.
Could you maybe have a look at the HCLK issue we are discussing? This thread could use some input from someone who has contact to the hardware guys.
