From: Mark Cave-Ayland Date: Wed, 20 Dec 2023 13:16:32 +0000 (+0000) Subject: next-cube.c: don't pulse SCSI DMA IRQ upon reception of FLUSH command X-Git-Tag: v9.0.0-rc0~131^2~9 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=6f2454be58ebe656ce5ffffb03765e8d0adaac8c;p=thirdparty%2Fqemu.git next-cube.c: don't pulse SCSI DMA IRQ upon reception of FLUSH command Normally a DMA FLUSH command is used to ensure that data is completely written to the device and/or memory, so remove the pulse of the SCSI DMA IRQ if a DMA FLUSH command is received. This enables the NeXT ROM monitor to start to load from a SCSI disk.
