This works around and issue where the INVLPG instruction may miss invalidating kernel TLB entries. I do expect an eventual microcode fix for this. When the microcode version numbers are known, we can circle back around and add them the model table to disable this workaround. --- The following changes since commit 7d8accfaa0ab65e4282c8e58950f7d688342cd86: hwmon: (k10temp) Add PCI ID for family 19, model 78h (2023-05-08 11:36:19 +0200) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git tags/x86_urgent_for_6.4-rc4 for you to fetch changes up to ce0b15d11ad837fbacc5356941712218e38a0a83: x86/mm: Avoid incomplete Global INVLPG flushes (2023-05-17 08:55:02 -0700) ---------------------------------------------------------------- Work around a TLB invalidation issue in recent hybrid CPUs ---------------------------------------------------------------- Dave Hansen (1): x86/mm: Avoid incomplete Global INVLPG flushes arch/x86/mm/init.c | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+)
