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.
Do we need some modification to test AFBC by weston-simple-dma-egl ?
I have a buildroot system with weston-10.0.9 and mesa 21.3.5.
After launch weston, I run weston-simple-dmabuf-egl, but from the output
of sys/kernel/debug/dri/0/state, the weston is still use Smart0-win0,
which is
a non-AFBC window.
Do i need to modify the vop2 driver to set one Cluster window as primary
plane?
