When a transfer is added to the transfer queue, we reserve some space in the cmdbuf. When the transfer queue is flushed, we patch the reserved space with the final transfer command for each transfer. This allows us to get rid of VIRGL_MAX_TBUF_DWORDS. Our internal use of u_upload is special. We expect it to be mapped persistently and coherently until we flush. The space for the transfer command must be reserved at map time rather than at unmap time. Signed-off-by: Chia-I Wu <olvaffe@gmail.com>
