x86/xen: Set default memory type for PV guests to WB (2023-06-16 11:22:33 +0200)
---------------------------------------------------------------- - A serious scrubbing of the MTRR code including adding a new map mechanism in order to look up the memory type of a region easily. Also address memory range lookup issues like returning an invalid memory type. Furthermore, this handles the decoupling of PAT from MTRR more naturally. All work by Juergen Gross
---------------------------------------------------------------- Borislav Petkov (AMD) (1): x86/mtrr: Unify debugging printing
Juergen Gross (17): x86/mtrr: Remove physical address size calculation x86/mtrr: Replace size_or_mask and size_and_mask with a much easier concept x86/mtrr: Support setting MTRR state for software defined MTRRs x86/hyperv: Set MTRR state when running as SEV-SNP Hyper-V guest x86/xen: Set MTRR state when running as Xen PV initial domain x86/mtrr: Replace vendor tests in MTRR code x86/mtrr: Have only one set_mtrr() variant x86/mtrr: Move 32-bit code from mtrr.c to legacy.c x86/mtrr: Allocate mtrr_value array dynamically x86/mtrr: Add get_effective_type() service function x86/mtrr: Construct a memory map with cache modes x86/mtrr: Add mtrr=debug command line option x86/mtrr: Use new cache_map in mtrr_type_lookup() x86/mtrr: Don't let mtrr_type_lookup() return MTRR_TYPE_INVALID x86/mm: Only check uniform after calling mtrr_type_lookup() x86/mtrr: Remove unused code x86/xen: Set default memory type for PV guests to WB
