radv/ac: Fix shared memory offset calculation
The index passed to get_shared_memory_ptr is an attribute slot index, i.e. the index of a vec4 within LDS. Therefore this must be scaled by sizeof(vec4) to give the LDS byte offset. Fixes: f4e499ec791 ("radv: add initial non-conformant radv vulkan driver") Signed-off-by: Alex Smith <[email protected]> Reviewed-by: Bas Nieuwenhuizen <[email protected]> CC: <[email protected]>
