From e9bd2e73793bf0f7fcd8f94b532bb8f5c5b44171 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 9 Jul 2009 22:14:35 -0300 Subject: [PATCH] i7core_edac: Adds write unlock to MC registers The public Intel Xeon 5500 volume 2 datasheet describes, on page 53, session 2.6.7 a register that can lock/unlock Memory Controller the configuration register, called MC_CFG_CONTROL. Adds support for it in the hope that software error injection would work. With my tests with Xeon 35xx, there's still something missing. With a program that does sequencial bit writes at dev 0.0, sometimes, it produces error injection, after unblocking the MC_CFG_CONTROL (and, sometimes, it just locks my testing machine). I'll try later to discover by trial and error what's the register that solves this issue on Xeon 35xx. Signed-off-by: Mauro Carvalho Chehab --- Reading git-format-patch failed
