From df5446196cd81c4a714f45f92fb379c795c1edb5 Mon Sep 17 00:00:00 2001 From: "Jonathan A. Kollasch" Date: Fri, 17 Jul 2015 07:47:41 -0500 Subject: amd/model_fxx: set CPU_ADDR_BITS to 40 on all K8 machines Moves the K8 CPU_ADDR_BITS definition from socket to model. Previously socket_F was not setting CPU_ADDR_BITS correctly. Tested on Sun Ultra 40 M2 with two 2nd-gen Opterons w/ 2x4x2GiB DIMMs. Most if not all K8-based chips support 40-bit physical addresses, with possible exception of IA32-only K8-based Athlon XP-M chips. Probably irrelevant, unless your machine has enough memory (at least 60 to 64GiB before MMIO hoisting) to exceed the CPU_ADDR_BITS default of 36 from src/cpu/x86/Kconfig.
