Subject: [PATCH v3 0/8] AMD64 EDAC fixes
Date: Wed, 21 Aug 2019 23:59:53 +0000
Message-ID: <20190821235938.118710-1-Yazen.Ghannam@amd.com> (raw)

From: Yazen Ghannam <yazen.ghannam@amd.com>

Hi Boris,

This set contains a few fixes for some changes merged in v5.2. There
are also a couple of fixes for older issues. In addition, there are a
couple of patches to add support for Asymmetric Dual-Rank DIMMs.

I don't have the failing config readily available that you used, but I
believe I found the issue. Please let me know how it goes.

I've also added RFC patches to avoid the "ECC disabled" message for
nodes without memory. I haven't fully tested these, but I wanted to get
your thoughts. Here's an earlier discussion:
https://lkml.kernel.org/r/20180321191335.7832-1-Yazen.Ghannam@amd.com

Thanks,
Yazen

v2->v3:
* Drop Fixes: tags in patch 1.
* Add detection of x8 DRAM devices in patches 2 and 3.
* Fix Chip Select size printing in patch 4.
* Added RFC patches to avoid "ECC disabled" message for nodes without memory.

v1->v2:
* Squash patches 1 and 2 together.


Yazen Ghannam (10):
  EDAC/amd64: Support more than two controllers for chip selects
    handling
  EDAC/amd64: Recognize DRAM device type with EDAC_CTL_CAP
  EDAC/amd64: Initialize DIMM info for systems with more than two
    channels
  EDAC/amd64: Find Chip Select memory size using Address Mask
  EDAC/amd64: Decode syndrome before translating address
  EDAC/amd64: Cache secondary Chip Select registers
  EDAC/amd64: Support Asymmetric Dual-Rank DIMMs
  EDAC/amd64: Gather hardware information early
  EDAC/amd64: Use cached data when checking for ECC
  EDAC/amd64: Check for memory before fully initializing an instance
