igt_vc4_get_cleared_bo ()

uint32_t
igt_vc4_get_cleared_bo (int fd,
                        size_t size,
                        uint32_t clearval);

This helper returns a new BO with the given size, which has just been cleared using the render engine.

igt_vc4_get_param ()

uint64_t
igt_vc4_get_param (int fd,

This wraps the GET_PARAM ioctl.

Returns the current value of the parameter. If the parameter is invalid, returns 0.
