This patch adds ATAPI support to the sata_promise driver. This has been tested on both first- and second-generation chips (20378 and 20575), and with both SATAPI and PATAPI devices. CD-writing works. SATAPI DMA works on second-generation chips, but on first-generation chips SATAPI is limited to PIO due to what appears to be HW limitations. PATAPI DMA works on both first- and second-generation chips, but requires the separate PATA support patch before it can be used on TX2plus chips. The functional changes to the driver are: - remove ATA_FLAG_NO_ATAPI from PDC_COMMON_FLAGS - add ->check_atapi_dma() operation to enable DMA for bulk data transfers but force PIO for other ATAPI commands; this filter is from Promise's driver and largely matches pata_pdc207x.c - use a more restrictive ->check_atapi_dma() on first-generation chips to force SATAPI to always use PIO - add handling of ATAPI protocols to pdc_qc_prep(), pdc_host_intr(), and pdc_qc_issue_prot(): ATAPI_DMA is handled by the driver while non-DMA protocols are handed over to libata generic code - add pdc_issue_atapi_pkt_cmd() to handle the initial steps in issuing ATAPI DMA commands before sending the actual CDB; this procedure was ported from Promise's driver Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Jeff Garzik <jeff@garzik.org> |
