Author: Rafael Antognolli <[email protected]> Date: Wed Feb 28 16:11:34 2018 -0800 i965/miptree: Add new clear color BO for winsys aux buffers Add an extra BO to store clear color when we receive the aux buffer from the window system. Since we have no control over the aux buffer size in this case, we need the new BO to store only the clear color. v5: - Better subject (Jordan). - Drop alignment from brw_bo_alloc().
