Subject: [PATCH 15/15] ide: add ide_tune_dma() helper
Date: Fri, 19 Jan 2007 01:32:40 +0100 [thread overview]
Message-ID: <20070119003240.14846.32464.sendpatchset@localhost.localdomain> (raw)
In-Reply-To: <20070119003058.14846.43637.sendpatchset@localhost.localdomain>
[PATCH] ide: add ide_tune_dma() helper
After reworking the code responsible for selecting the best DMA
transfer mode it is now possible to add generic ide_tune_dma() helper.
Convert some IDE PCI host drivers to use it (the ones left need more work).
