Subject: [ 15/29] ata_piix: Fix DVD not dectected at some Haswell platforms
Date: Wed, 10 Apr 2013 15:49:33 -0700 [thread overview]
Message-ID: <20130410224805.680267274@linuxfoundation.org> (raw)
In-Reply-To: <20130410224804.061806042@linuxfoundation.org>
3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Youquan Song <youquan.song@intel.com>
commit b55f84e2d527182e7c611d466cd0bb6ddce201de upstream.
There is a quirk patch 5e5a4f5d5a08c9c504fe956391ac3dae2c66556d
"ata_piix: make DVD Drive recognisable on systems with Intel Sandybridge
chipsets(v2)" fixing the 4 ports IDE controller 32bit PIO mode.
We've hit a problem with DVD not recognized on Haswell Desktop platform which
includes Lynx Point 2-port SATA controller.
This quirk patch disables 32bit PIO on this controller in IDE mode.
v2: Change spelling error in statememnt pointed by Sergei Shtylyov.
v3: Change comment statememnt and spliting line over 80 characters pointed by
Libor Pechacek and also rebase the patch against 3.8-rc7 kernel.
