2009-12-12Revert "monitor: Command-line flag to enable control mode"Gerd Hoffmann
This reverts commit adcb181afe5a951c521411c7a8e9d9b791aa6742. Conflicts: monitor.h Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-12-12chardev: make chardevs specified in config file work.Gerd Hoffmann
The patch decuples the -chardev switch and the actual chardev initialization. Without this patch qemu ignores chardev entries coming via -readconfig. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-12-12qdev: also match bus name for global propertiesGerd Hoffmann
i.e. -global PCI.<property>=<value> will set a default property for all PCI devices. Also works for the compat properties used by machine types. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-12-12qdev: add command line option to set global defaults for properties.Gerd Hoffmann
This patch adds infrastructure and command line option for setting global defaults for device properties, i.e. you can for example use -global virtio-blk-pci.vectors=0 to turn off msi by default for all virtio block devices. The config file syntax is: [global] driver = "virtio-blk-pci" property = "vectors" value = "0" This can also be used to set properties for devices which are not created via -device but implicitly via machine init, i.e. -global isa-fdc,driveA=<name> This patch uses the mechanism which configures properties for the compatibility machine types (pc-0.10 & friends). The command line takes precedence over the machine type values. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-12-12qdev: make compat stuff more genericGerd Hoffmann
This patch renames the compat properties into global properties and makes them more generic. The compatibility stuff is only one of multiple possible users now. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-12-12kvm: x86: Save/restore exception_indexJan Kiszka
As KVM now makes use of exception_index to keep pending exceptions, we have to save&restore this field as well. NOTE: We have to nail the arch-independent exception_index down to a certain bit width for proper vmstate processing, namely to 32 bit.

2009-12-12qdev: Replace device names containing whitespaceMarkus Armbruster
Device names with whitespace require quoting in the shell and in the monitor. Some of the offenders are also overly long. Some have a more convenient alias, some don't. The place for verbose device names is DeviceInfo member desc. The name should be short & sweet.

2009-12-12qdev: Separate USB product description from qdev nameMarkus Armbruster
Using the qdev name for the product description makes for inconvenient qdev names. Put the product description in new USBDeviceInfo member product_desc. Make usb_qdev_init() use it. No user or guest visible change, since the value is still the same. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-12-12fix rtc-td-hack on host without high-res timersGleb Natapov
On hosts without high-res timers it is impossible to inject rtc interrupt faster then 1kHz. Windows sometimes configures RTC to generate 1kHz interrupts, so we can't inject missed interrupts when running on such hosts. Always injecting an interrupt on REG_C read is also not an option since Windows wait for REG_C to become zero with interrupt disabled during boot. This patch uses mixed approach: accelerate timer + inject up to 1000 interrupts on REG_C read. Signed-off-by: Gleb Natapov <gleb@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-12-12virtio: verify features on loadMichael S. Tsirkin
migrating between hosts which have different features might break silently, if the migration destination does not support some features supported by source. Prevent this from happening by comparing acked feature bits with the mask supported by the device. Signed-off-by: Michael S.

2009-12-12Do not abort on qemu_malloc(0) in production buildsAnthony Liguori
qemu_malloc() does not allow size=0 to be passed in and aborts on this behavior. Unfortunately, there is good reason to believe that within qemu, there are a number of, so far, undetected places that assume size=0 can be safely passed. Since we do not want to abort unnecessarily in production builds, return qemu_malloc(1) whenever the version file indicates that this is a production build.

2009-12-07monitor: Introduce 'block_passwd' commandLuiz Capitulino
When using encrypted disk images, QEMU will prompt the user for passwords when started. This makes sense for the user protocol, but doesn't for QMP. The solution is to have Monitor command which allows the user or a Client to set passwords in advance, so that we avoid the prompt completely. This is what block_passwd does, for example: (QEMU) block_passwd ide0-hd0 foobar Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-12-07cpuid: Fix multicore setup on IntelAndre Przywara
The multicore CPUID code detects whether the guest is an Intel or an AMD CPU, because the Linux kernel is picky about the CmpLegacy bit. KVM by default passes through the host's vendor, which was not catched by the code. So fork out the vendor determining bits into a separate function to be used from both places and always get the real vendor. This fixes KVM's multicore setup on Intel CPUs.

2009-12-07kvm: x86: Fix initial kvm_has_msr_starJan Kiszka
KVM_GET_MSR_INDEX_LIST returns -E2BIG when the provided space is too small for all MSRs. But this is precisely the error we trigger with the initial request in order to obtain that size. Do not fail in that case. This caused a subtle corruption of the guest state as MSR_STAR was not properly saved/restored. The corruption became visible with latest kvm optimizing the MSR updates.
