<pre>Oh, the kernel doesn't like setting swizzle unknown:
/* If we can't handle the swizzling, make it untiled. */
if (args->swizzle_mode == I915_BIT_6_SWIZZLE_UNKNOWN) {
args->tiling_mode = I915_TILING_NONE;
args->swizzle_mode = I915_BIT_6_SWIZZLE_NONE;
args->stride = 0;
}
and of course doesn't flag an error to the user. So it is just a broken API.</pre>
