[Qemu-devel] [PATCH] ATAPI CDROM DMA support is incomplete

Hi, some time ago, ATAPI DMA support was added to hw/ide.c, but the DMA support is incomplete: DMA data transfers are implemented for ATAPI/SCSI READ commands only (GPCMD_READ_10, GPCMD_READ_12, GPCMD_READ_CD), but all other ATAPI/SCSI commands still try to transfer data using PIO mode. Becaus
