Bernhard Kaindl de938c51d5 [PATCH] i386: Enable support for fixed-range IORRs to keep RdMem & WrMem in sync ... If our copy of the MTRRs of the BSP has RdMem or WrMem set, and we are running on an AMD64/K8 system, the boot CPU must have had MtrrFixDramEn and MtrrFixDramModEn set (otherwise our RDMSR would have copied these bits cleared), so we set them on this CPU as well. This allows us to keep the AMD64/K8 RdMem and WrMem bits in sync across the CPUs of SMP systems in order to fullfill the duty of system software to "initialize and maintain MTRR consistency across all processors." as written in the AMD and Intel manuals. If an WRMSR instruction fails because MtrrFixDramModEn is not set, I expect that also the Intel-style MTRR bits are not updated.
