[PATCH 0/7] whpx: i386: Some more changes

Posted by Mohamed Mediouni 2 weeks, 1 day ago

This applies on top of the "whpx: i386: bug fixes, feature probing and CPUID" series.

"target: i386: HLT type that ignores EFLAGS.IF" is probably the most worthwhile patch
here, and that not-quite-an-HLT might be what's needed to reduce CPU idle on KVM on
recent Windows versions too..

Based-on: <20260413205208.50643-1-mohamed@unpredictable.fr>

Mohamed Mediouni (7):
  whpx: i386: set apicbase value only on success
  whpx: i386: unknown MSR configurability
  whpx: i386: enable GuestIdleReg enlightenment
  whpx: i386: tighten APIC base validity check
  whpx: i386: ignore vpassist when kernel-irqchip=off
  target: i386: HLT type that ignores EFLAGS.IF
  whpx: i386: add HV_X64_MSR_GUEST_IDLE when !kernel-irqchip
