This patch-set resolves several emulator bugs. Each fix is independent of the others. The DR6 bug can occur during DR-access exit (regardless to unrestricted mode, MMIO and SPT). Changes in v2: Introduced kvm_register_readl and kvm_register_writel which consider long-mode and cs.l when reading the registers. Fixing the register read to respect 32/64 bit in hypercall handling, CR exit handling and VMX instructions handling. Thanks for re-reviewing the patch Nadav Amit (9): KVM: x86: bit-ops emulation ignores offset on 64-bit KVM: x86: Wrong emulation on 'xadd X, X' KVM: x86: Inter privilage level ret emulation is not implemeneted KVM: x86: emulation of dword cmov on long-mode should clear [63:32] KVM: x86: NOP emulation clears (incorrectly) the high 32-bits of RAX KVM: x86: check DR6/7 high-bits are clear only on long-mode KVM: x86: Hypercall handling does not considers opsize correctly KVM: vmx: handle_cr ignores 32/64-bit mode KVM: vmx: vmx instructions handling does not consider cs.l arch/x86/kvm/emulate.c | 31 ++++++++++++++++++++----------- arch/x86/kvm/vmx.c | 16 ++++++++-------- arch/x86/kvm/x86.c | 11 ++++++----- arch/x86/kvm/x86.h | 27 +++++++++++++++++++++++++++ 4 files changed, 61 insertions(+), 24 deletions(-)
