From 1dcf087af57a93ec7f24aa8be73e7ff0ffad22ca Mon Sep 17 00:00:00 2001 From: Artem Senichev Date: Tue, 13 Mar 2018 15:03:41 +0300 Subject: [PATCH] Fix POS and SPD-VPD_REC_NUM Hank Chang: When bringup this 4Socket 128DIMMs system, we hit the following VPD/SPD issue and suspected it might be related to the VPD_REC_NUM numbering algorithm issue then caused the SPD cache overlap for the 4 sockets case. So we simply tried to jump the $aff_pos offset from 16 to 64 for each Proc and the issue was fixed/gone.
