Modified Files: src/sys/arch/mac68k/include: psc.h src/sys/arch/mac68k/mac68k: psc.c src/sys/arch/mac68k/obio: esp.c espvar.h Log Message: PR port-mac68k/24883 Support DMA xfer for SCSI adapter of AV Mac (660/840AV), written by Michael Zucca. This improves disk I/O performance by nearly one order of magnitude. In addition, interrupt storm due to heavy disk PIO is resolved. I'm deeply grateful to Michael Zucca for his analysis of DMA engine and submission of PR. I also thank Izumi Tsutsui (useful comments on port-mac68k@) and Martin Husemann (test on 660AV).
