But you now do! You need something like:
static void get_tiling_and_swizzle(int fd,
struct buf_data *buf,
int *tiling, int *swizzle)
{
struct local_i915_gem_get_tiling_v2 {
uint32_t handle;
uint32_t tiling_mode;
uint32_t swizzle_mode;
uint32_t phys_swizzle_mode;
} tiling;
#define LOCAL_IOCTL_I915_GEM_GET_TILING DRM_IOWR (DRM_COMMAND_BASE + DRM_I915_GEM_GET_TILING, struct local_i915_gem_get_tiling_v2)
memset(&tiling, 0, sizeof(tiling));
tiling.handle = buf->handle;
do_ioctl(fd, LOCAL_IOCTL_I915_GEM_GET_TILING, &tiling);
igt_require(tiling.phys_swizzle == tiling.swizzle_mode ||
intel_gen(intel_get_drm_devid(fd)) >= 5); /* old kernel? */
*tiling = tiling.tilling_mode;
*swizzle = tiling.swizzle_mode;
}
