[PATCH v2 0/3] Updates for AMD Family 1Ah-based Models

[PATCH v2 0/3] Updates for AMD Family 1Ah-based Models

[Avadhut Naik]

This patchset adds support for amd64_edac module and temperature monitoring,
through k10temp driver, on AMD's Family 1Ah-based models.

The first patch adds the required PCI IDs for models 00h-1Fh, 20h and
40h-4Fh.

The second patch adds the required support in k10temp driver for AMD's
Family 1Ah-based models.

The third patch adds support in amd64_edac module for models 00h-1Fh and
40h-4Fh.

Changes in v2:
 - Modify commit message of the first patch according to the feedback
received.

v1: https://lore.kernel.org/linux-edac/20230706171323.3722900-1-avadhut.naik@amd.com/T/#t

[PATCH v2 1/3] x86/amd_nb: Add PCI IDs for AMD Family 1Ah-based models

[Avadhut Naik]

From: Avadhut Naik <Avadhut.Naik@amd.com>

Add new PCI Device IDs, required to support AMD's new Family 1Ah-based
models 00h-1Fh, 20h and 40h-4Fh.

Since, models 40h-4Fh and model 20h share some design aspects, the PCI
IDs defined in this patch for model 20h are shared by models 40h-4Fh.

Avoid having "This patch" or "This commit" in the commit message. It is
tautologically useless.

Also, do

$ git grep 'This patch' Documentation/process

for more details.
