Daniel P. Berrangé ce14f24611 hw/dma/xlnx_csu_dma: skip automatic zero-init of large array ... The 'xlnx_csu_dma_src_notify' method has a 4k byte array used for copying DMA data. Skip the automatic zero-init of this array to eliminate the performance overhead in the I/O hot path. The 'buf' array will be fully initialized when data is copied. Signed-off-by: Daniel P.
