artsata -- Intel i31244 Serial ATA disk controller driver
artsata* at pci? dev ? function ? flags 0x0000 options PCIIDE_I31244_DISABLEDMA
The artsata driver supports the Intel i31244 Serial ATA and controllers, and provides the interface with the hardware for the ata(4) driver. The 0x0002 flag forces the artsata driver to disable DMA on chipsets for which DMA would normally be enabled. This can be used as a debugging aid, or to work around problems where the SATA controller is wired up to the system incorrectly.

Early samples of the Intel i31244 Serial ATA controller revision 0 had a bug affecting DMA data transfers. Full production samples have been fixed, but have the same revision number. The PCIIDE_I31244_DISABLEDMA option can be used to disable DMA on the buggy revisions. NetBSD 9.1 February 12, 2005 NetBSD 9.1
