2009-12-12qdev: make compat stuff more genericGerd Hoffmann6-16/+24
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 Kiszka2-1/+2
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 Armbruster19-63/+56
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 Armbruster11-1/+15
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 Natapov1-0/+17
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. Tsirkin4-6/+37
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 Liguori2-7/+30
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 Capitulino2-0/+30
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 Przywara1-15/+31
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 Kiszka1-2/+2
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.

2009-12-05Add S390 maintainer informationv0.12.0-rc0Alexander Graf1-0/+3
This patch adds information about who handles what when it comes to S390. I'll gladly support anything that's related to the device emulation model and S390 KVM parts. Since this patchset doesn't implement S390 CPU emulation, I left that part with a question mark. As soon as Uli's patchset gets committed I'd recommend setting him there.

2009-12-05Set default console to virtio on S390xAlexander Graf1-0/+26
All "normal" system emulation targets in qemu I'm aware of display output on either VGA or serial output. Our S390x virtio machine doesn't have such kind of legacy hardware. So instead we need to default to a virtio console. I'm not particularly proud of this patch. It would be a lot better to have something in the machine description that tells us about the default terminal.

2009-12-05S390 GDB stubAlexander Graf1-0/+52
In order to debug funny kernel breakages it's always good to have a working gdb stub around. While Uli's patches don't include one one, I needed one that's at least good enough for 'bt' and some variable examinations during early bootup. So here it is - the absolute basics to get the qemu gdb stub running with s390x targets. Sgined-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

In order to use the new S390x virtio bus we just introduced, we also need a machine description that sets up the machine according to our PV specification.
