2011-01-23kvm: Improve reporting of fatal errorsJan Kiszka
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.

2011-01-23kvm: Stop on all fatal exit reasonsJan Kiszka
Ensure that we stop the guest whenever we face a fatal or unknown exit reason. If we stop, we also have to enforce a cpu loop exit. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
2011-01-23kvm: x86: Swallow KVM_EXIT_SET_TPRJan Kiszka
This exit only triggers activity in the common exit path, but we should accept it in order to be able to detect unknown exit types. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

2011-01-21kvm: x86: Prevent sign extension of DR7 in guest debugging modeJan Kiszka
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).

2011-01-21kvm: x86: Remove obsolete SS.RPL/DPL aligmentJan Kiszka
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: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-01-21kvm: x86: Fix DPL write back of segment registersJan Kiszka
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: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Avi Kivity <avi@redhat.com>

Pass a table instead of multiple args. Note: kvm_inject_x86_mce(env, bank, status, mcg_status, addr, misc, abort_on_error); is equal to: struct kvm_x86_mce mce = { .bank = bank, .status = status, .mcg_status = mcg_status, .addr = addr, .misc = misc, }; kvm_inject_x86_mce_on(env, &mce, abort_on_error); Signed-off-by: Hidetoshi Seto <seto.hidetoshi@jp.fujitsu.com> Signed-off-by: Jin Dongming <jin.dongming@np.css.fujitsu.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

2011-01-21Add "broadcast" option for mce commandJin Dongming
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: Jin Dongming <jin.dongming@np.css.fujitsu.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

2011-01-20gt64xxx: set isa_mem_base during registrationAurelien Jarno
isa_mem_base is computed from registers during reset, but due to QEMU limitations some devices (e.g. VGA card) need to know it earlier when they are registered. Workaround this by setting the value during registration instead of reset. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-01-20hw/pl190.c: Fix writing of default vector addressPeter Maydell
The PL190 implementation keeps the default vector address in vect_addr[16], but we weren't using this for writes to the DEFVECTADDR register. As a result of this fix the default_addr structure member is unused and we can delete it.

2011-01-20target-ppc: fix wrong NaN testsAurelien Jarno
Some tests in FPU emulation code were wrongly using float64_is_nan() before commit 185698715dfb18c82ad2a5dbc169908602d43e81, and wrongly using float64_is_quiet_nan() after. Fix them by using float64_is_any_nan() instead. Reviewed-by: Nathan Froyd <froydnj@codesourcery.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-01-20target-ppc: fix sNaN propagationAurelien Jarno
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.

2011-01-20pci: deassert intx on reset.Isaku Yamahata
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: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
