Changed since v1: - PDMA transfer residual is calculated earlier. - End of DMA flag check is now polled (if there is any residual). Changed since v2: - Bail out of transfer loops when Gated IRQ gets asserted. - Make udelay conditional on board type. - Drop sg_tablesize patch due to performance regression. Changed since v3: - Add Ondrej's workaround for corrupt WRITE commands on DTC boards. - Reset the 53c400 logic after any short PDMA transfer. - Don't fail the transfer if the 53c400 logic got a reset. Changed since v4: - Bail out of transfer loops when Gated IRQ gets asserted. (Again.) - Always call wait_for_53c80_registers() at end of transfer. - Drain chip buffers after PDMA receive is interrupted. - Rework residual calculation. - Add new patch to correct DMA terminology. Finn Thain (2): g_NCR5380: Cleanup comments and whitespace g_NCR5380: Use unambiguous terminology for PDMA send and receive Ondrej Zary (4): g_NCR5380: Fix PDMA transfer size g_NCR5380: End PDMA transfer correctly on target disconnection g_NCR5380: Limit PDMA send to 512 B to avoid data corruption on DTC3181E g_NCR5380: Re-work PDMA loops drivers/scsi/g_NCR5380.c | 260 +++++++++++++++++++++++++---------------------- 1 file changed, 139 insertions(+), 121 deletions(-) -- 2.13.0
