I am just using the drm driver for coding my custom vop driver for rockchip. It's working but I have a problem, the vop is not triggering the irqs and I am not able to use the status registers for detect the vblank region. Here's my code
status=*((unsigned int *)(vop+RK3328_INTR_STATUS0))
but it is always 0. I enabled the irqs in the vop register but nothing happens. Thanks for help
