Jason Baron	7ee40b897d	ie31200_edac: Introduce the driver ... Add a driver for the E3-1200 series of Intel DRAM controllers, based on the following E3-1200 specs: http://www.intel.com/content/www/us/en/processors/xeon/xeon-e3-1200-family-vol-2-datasheet.html http://www.intel.com/content/www/us/en/processors/xeon/xeon-e3-1200v3-vol-2-datasheet.html I've tested this on bad memory hardware, and observed correlating bad reads and uncorrected memory errors as reported by the driver. Tested against: CPU E3-1270 v3 @ 3.50GHz : 8086:0c08 (haswell) CPU E3-1270 V2 @ 3.50GHz : 8086:0158 (ivy bridge) CPU E31270 @ 3.40GHz : 8086:0108 (sandy bridge) Signed-off-by: Jason Baron <jbaron@akamai.com> Link: http://lkml.kernel.org/r/95c83e80dd40b5377e8bb206285c5d95ac623872.1403818526.git.jbaron@akamai.com [ Boris: realign defines ] Signed-off-by: Borislav Petkov <bp@suse.de>	2014-07-04 14:00:26 +02:00
