2009-12-12qdev: Rename USBDevice member devname to product_descMarkus Armbruster
It's not a device name, it's the USB product description string. 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.

2009-12-05Add S390 maintainer informationv0.12.0-rc0Alexander Graf
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 Graf
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 Graf
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>
2009-12-05Add S390x virtio machine descriptionAlexander Graf
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. Let's add that machine description and be happy! Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2009-12-05Add S390x virtio machine busAlexander Graf
On S390x we don't want to go through the hassle of emulating real existing hardware, because we don't need to for running Linux. So let's instead implement a machine that is 100% based on VirtIO which we fortunately implement already. This patch implements the bus that is the groundwork for such an S390x virtio machine.

2009-12-05Add support for S390x system emulationAlexander Graf
Let's enable the basics for system emulation so we can run virtual machines with KVM! Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2009-12-05Allocate physical memory in low virtual address spaceAlexander Graf
KVM on S390x requires the virtual address space of the guest's RAM to be within the first 256GB. The general direction I'd like to see KVM on S390 move is that this requirement is losened, but for now that's what we're stuck with. So let's just hack up qemu_ram_alloc until KVM behaves nicely :-). Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2009-12-05Add KVM support for S390xAlexander Graf
S390x was one of the first platforms that received support for KVM back in the day. Unfortunately until now there hasn't been a qemu implementation that would enable users to actually run guests. So let's include support for KVM S390x in qemu! Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2009-12-05S/390 fake TCG implementationAlexander Graf
Qemu won't let us run a KVM target without having host TCG support. Well, for now we don't have any so let's implement a fake target that only stubs out everything. I tried to keep the patch as close to Uli's source as possible, so whenever he feels like it he can easily diff his version against this one.
