From cbfdc385ec93be8741f2af13cee03fac2dc1d236 Mon Sep 17 00:00:00 2001 From: Michael Neuling Date: Wed, 14 Jun 2017 17:34:11 +1000 Subject: [PATCH] mambo: Update P9 PVR to reflect Scale out 24 core chips The P9 PVR bits 48:51 don't indicate a revision but instead different configurations. From BookIV we have: Bits: Configuration 0: Scale out 12 cores 1: Scale out 24 cores 2: Scale up 12 cores 3: Scale up 24 cores Skiboot will mostly the use "Scale out 24 core" configuration (ie. SMT4 not SMT8) so reflect this in mambo.
