But I strongly recommend *not* relying on it when possible and\nusing kernel-irqchip=on instead. On Windows 10 however that's more murky\nbecause PIC interrupt injection is broken (interrupts don't wake the vCPU\nfrom HLT) in that case.\n\n\"whpx: i386: wire up feature probing\" is yet another commit adding a code path\nnot used on Windows 10. It'll tell the user today which CPU features they set\nare incompatible with the hardware but it does not sync that to the CPUID view\nthat the guest has.\n\nAnd then another commit to enable x2apic emulation by default even for\nkernel-irqchip=off + re-introducing provided by QEMU enlightenments in a more\nfunctional form to signal that the x2apic can be used. I'm not aware of the\nactual vmware freq leaf being used though.\n\n\"whpx: x2apic emulation for kernel-irqchip=off follow-up\" is rolled into this series.\n\nChanges in v2:\n\n- GCC warned when a variable name was re-used within a different (but overlapping)\nscope in the same function. It also warned with a -Werror=maybe-uninitialized for\nthe MSR write case. Address those\n- make the in-KVM enlightenments path available on Windows 11 too when -M hyperv=off.\n\nMohamed Mediouni (6):\n target/i386: emulate: include name of unhandled instruction\n whpx: i386: x2apic emulation\n whpx: i386: wire up feature probing\n whpx: i386: disable TbFlushHypercalls for emulated LAPIC\n whpx: i386: enable x2apic by default for user-mode LAPIC\n whpx: i386: reintroduce enlightenments for Windows 10\n\n accel/whpx/whpx-common.c | 2 +\n include/system/whpx-internal.h | 4 +\n target/arm/whpx/whpx-all.c | 1 +\n target/i386/cpu.c | 25 ++++\n target/i386/emulate/x86_emu.c | 4 +-\n target/i386/whpx/whpx-all.c | 265 ++++++++++++++++++++++++++++++++-\n target/i386/whpx/whpx-i386.h | 4 +\n 7 files changed, 298 insertions(+), 7 deletions(-)\n create mode 100644 target/i386/whpx/whpx-i386.h"}
