From 7bb67c14fd3778504fb77da30ce11582336dfced Mon Sep 17 00:00:00 2001 From: Shannon Nelson Date: Wed, 14 Nov 2007 16:59:51 -0800 Subject: I/OAT: Add support for version 2 of ioatdma device Add support for version 2 of the ioatdma device. This device handles the descriptor chain and DCA services slightly differently: - Instead of moving the dma descriptors between a busy and an idle chain, this new version uses a single circular chain so that we don't have rewrite the next_descriptor pointers as we add new requests, and the device doesn't need to re-read the last descriptor. - The new device has the DCA tags defined internally instead of needing them defined statically.
