Subject: [PATCH 1/1] x86/platform/UV: Fix critical UV MMR address error
Date: Wed, 28 Mar 2018 12:40:11 -0500 [thread overview]
Message-ID: <20180328174011.041801248@stormcage.americas.sgi.com> (raw)
In-Reply-To: <20180328174010.882366342@stormcage.americas.sgi.com>
[-- Attachment #1: fix-gam-mmioh-config1 --]
[-- Type: text/plain, Size: 1076 bytes --]
A critical error was found testing the fixed UV4 HUB in that an MMR
address was found to be incorrect. This causes the virtual address
space for accessing the MMIOH1 region to be allocated with the
incorrect size.
