Report KVM_EXIT_UNKNOWN, KVM_EXIT_FAIL_ENTRY, and KVM_EXIT_EXCEPTION with more details to stderr. The latter two are so far x86-only, so move them into the arch-specific handler. Integrate the Intel real mode warning on KVM_EXIT_FAIL_ENTRY that qemu-kvm carries, but actually restrict it to Intel CPUs. Moreover, always dump the CPU state in case we fail.

This unbreaks guest debugging when the 4th hardware breakpoint used for guest debugging is a watchpoint of 4 or 8 byte lenght. The 31st bit of DR7 is set in that case and used to cause a sign extension to the high word which was breaking the guest state (vm entry failure).

This seems to date back to the days KVM didn't support real mode. The check is no longer needed and, even worse, is corrupting the guest state in case SS.RPL != DPL. Signed-off-by: NJan Kiszka <jan.kiszka@siemens.com> Signed-off-by: NAvi Kivity <avi@redhat.com>

The DPL is stored in the flags and not in the selector. In fact, the RPL may differ from the DPL at some point in time, and so we were corrupting the guest state so far. Signed-off-by: NJan Kiszka <jan.kiszka@siemens.com> Signed-off-by: NAvi Kivity <avi@redhat.com>

When the following test case is injected with mce command, maybe user could not get the expected result. DATA command cpu bank status mcg_status addr misc (qemu) mce 1 1 0xbd00000000000000 0x05 0x1234 0x8c Expected Result panic type: "Fatal Machine check" That is because each mce command can only inject the given cpu and could not inject mce interrupt to other cpus. So user will get the following result: panic type: "Fatal machine check on current CPU" "broadcast" option is used for injecting dummy data into other cpus. Injecting mce with this option the expected result could be gotten. Usage: Broadcast[on] command broadcast cpu bank status mcg_status addr misc (qemu) mce -b 1 1 0xbd00000000000000 0x05 0x1234 0x8c Broadcast[off] command cpu bank status mcg_status addr misc (qemu) mce 1 1 0xbd00000000000000 0x05 0x1234 0x8c Signed-off-by: NJin Dongming <jin.dongming@np.css.fujitsu.com> Signed-off-by: NMarcelo Tosatti <mtosatti@redhat.com>

Some tests in FPU emulation code were wrongly using float64_is_nan() before commit 18569871, and wrongly using float64_is_quiet_nan() after. Fix them by using float64_is_any_nan() instead. Reviewed-by: NNathan Froyd <froydnj@codesourcery.com> Signed-off-by: NAurelien Jarno <aurelien@aurel32.net>

The current FPU code returns 0.0 if one of the operand is a signaling NaN and the VXSNAN exception is disabled. fload_invalid_op_excp() doesn't return a qNaN in case of a VXSNAN exception as the operand should be propagated instead of a new qNaN to be generated. Fix that by calling fload_invalid_op_excp() only for the exception generation (if enabled), and use the softfloat code to correctly compute the result.

deassert intx on device reset. So far pci_device_reset() is used for system reset. In that case, interrupt controller is reset at the same time so that all irq is are deasserted. But now pci bus reset/flr is supported, and in that case irq needs to be disabled explicitly. Signed-off-by: NIsaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: NMichael S.
