The kernel will return a 32-bit handle that can be used to manage the buffer with the DRM … Webgem_set_caching () void gem_set_caching (int fd, uint32_t handle, uint32_t caching);. This wraps the SET_CACHING ioctl. Note that this function internally calls igt_require() when SET_CACHING isn't available, hence automatically skips the test. Therefore always extract test logic which uses this into its own subtest.
