https://bugzilla.kernel.org/show_bug.cgi?id=199279 Bug ID: 199279 Summary: Missing support for BMI1 instruction emulation Product: Virtualization Version: unspecified Kernel Version: 4.16.* Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: low Priority: P1 Component: kvm Assignee: virtualization_kvm@xxxxxxxxxxxxxxxxxxxx Reporter: alexaltea123@xxxxxxxxx Regression: No The guest system I'm trying to run heavily relies on BMI1 instructions, in particular `bextr` and `andn`, to access MMIO registers. However, these instructions are not implemented in arch/x86/kvm/emulate.c. This triggers an internal error with `KVM_INTERNAL_ERROR_EMULATION` subcode. -- You are receiving this mail because: You are watching the assignee of the bug.
