Subject: [PATCH 13/15] ide: fix UDMA/MWDMA/SWDMA masks
Date: Fri, 19 Jan 2007 01:32:26 +0100	[thread overview]
Message-ID: <20070119003226.14846.87052.sendpatchset@localhost.localdomain> (raw)
In-Reply-To: <20070119003058.14846.43637.sendpatchset@localhost.localdomain>

[PATCH] ide: fix UDMA/MWDMA/SWDMA masks

* use 0x00 instead of 0x80 to disable ->{ultra,mwdma,swdma}_mask
* add udma_mask field to ide_pci_device_t and use it to initialize
  ->ultra_mask in aec62xx, pdc202xx_new and pdc202xx_old drivers
* fix UDMA masks to match with chipset specific *_ratemask()
  (alim15x3, hpt366, serverworks and siimage drivers need UDMA mask
   filtering method - done in the next patch)
