From: Tony Luck <tony.luck@xxxxxxxxx> [ Upstream commit 2eda374e883ad297bd9fe575a16c1dc850346075 ] New CPU #defines encode vendor and family as well as model. [ dhansen: vertically align 0's in invlpg_miss_ids[] ] Signed-off-by: Tony Luck <tony.luck@xxxxxxxxx> Signed-off-by: Dave Hansen <dave.hansen@xxxxxxxxxxxxxxx> Signed-off-by: Borislav Petkov (AMD) <bp@xxxxxxxxx> Link: https://lore.kernel.org/all/20240424181518.41946-1-tony.luck%40intel.com [ Ricardo: I used the old match macro X86_MATCH_INTEL_FAM6_MODEL() instead of X86_MATCH_VFM() as in the upstream commit. I also kept the ALDERLAKE_N name instead of ATOM_GRACEMONT. Both refer to the same CPU model. ] Signed-off-by: Ricardo Neri <ricardo.neri-calderon@xxxxxxxxxxxxxxx> --- I tested this backport on an Alder Lake system. Now pr_info("Incomplete global flushes, disabling PCID") is back in dmesg. I also tested on a Meteor Lake system, which unaffected by the INVLPG issue. The message in question is not there before and after the backport, as expected. --- arch/x86/mm/init.c | 16 ++++++---------- 1 file changed, 6 insertions(+), 10 deletions(-) diff --git a/arch/x86/mm/init.c b/arch/x86/mm/init.c index dd15fdee4536..17f1a89e26fc 100644 --- a/arch/x86/mm/init.c +++ b/arch/x86/mm/init.c @@ -257,21 +257,17 @@ static void __init probe_page_size_mask(void) } } -#define INTEL_MATCH(_model) { .vendor = X86_VENDOR_INTEL, \ - .family = 6, \ - .model = _model, \ - } /* * INVLPG may not properly flush Global entries * on these CPUs when PCIDs are enabled. */ static const struct x86_cpu_id invlpg_miss_ids[] = { - INTEL_MATCH(INTEL_FAM6_ALDERLAKE ), - INTEL_MATCH(INTEL_FAM6_ALDERLAKE_L ), - INTEL_MATCH(INTEL_FAM6_ALDERLAKE_N ), - INTEL_MATCH(INTEL_FAM6_RAPTORLAKE ), - INTEL_MATCH(INTEL_FAM6_RAPTORLAKE_P), - INTEL_MATCH(INTEL_FAM6_RAPTORLAKE_S), + X86_MATCH_INTEL_FAM6_MODEL(ALDERLAKE, 0), + X86_MATCH_INTEL_FAM6_MODEL(ALDERLAKE_L, 0), + X86_MATCH_INTEL_FAM6_MODEL(ALDERLAKE_N, 0), + X86_MATCH_INTEL_FAM6_MODEL(RAPTORLAKE, 0), + X86_MATCH_INTEL_FAM6_MODEL(RAPTORLAKE_P, 0), + X86_MATCH_INTEL_FAM6_MODEL(RAPTORLAKE_S, 0), {} }; -- 2.34.1
