Subject: [PATCH 1/2] x86/mce/amd: Extend "Disable error thresholding bank 4" to more models
Date: Mon, 7 Jan 2019 10:37:17 +0000	[thread overview]
Message-ID: <1546857399-2926-2-git-send-email-shirish.s@amd.com> (raw)
In-Reply-To: <1546857399-2926-1-git-send-email-shirish.s@amd.com>

The below patch added this quirk only for the first generation of family
15 processors, over time its noticed that its required for later
generations too.

"575203b4747c x86, MCE, AMD: Disable error thresholding bank 4 on some
models"

This patch extends the quirk to make it applicable till 7th Generation,
so as to address the below warning at boot:

"[Firmware Bug]: cpu 0, invalid threshold interrupt offset ..."
