Date: Sat, 14 Jul 2007 04:15:26 -0400 From: Jeff Garzik <jeff@...zik.org> To: linux-ide@...r.kernel.org Cc: LKML <linux-kernel@...r.kernel.org> Subject: [PATCH 0/3] libata: add taskfile protocol ->proto_mask info member These patches add proto_mask alongside pio_mask, mwdma_mask, and udma_mask. This is a more uniform way to export which features host controllers support (DMA? NCQ? ATAPI? ATAPI DMA?), rather than creating a new ATA_FLAG_xxx for each. This also opens the door to useful things like combining "if protocol==foo || protocol==bar" tests into a single mask, or masking between host and device to determine common protocols. Suggestions for improvement welcome, this is just the first cut. Stored on libata-dev.git#pmask for now.
