2009-12-07pci: interrupt disable bit supportMichael S. Tsirkin
Interrupt disable bit is mandatory in PCI spec. Implement it to make devices spec compliant. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Acked-by: Isaku Yamahata <yamahata@valinux.co.jp>
2009-12-07pci: interrupt status bit implementationMichael S. Tsirkin
interrupt status is a mandatory feature in PCI spec, so devices must implement it to be spec compliant. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Acked-by: Isaku Yamahata <yamahata@valinux.co.jp>
2009-12-07pci: prepare irq code for interrupt stateMichael S. Tsirkin
This rearranges code in preparation for interrupt state implementation. Changes: - split up bus walk away from interrupt handling into a subroutine - change irq_state from an array to bitmask - verify that irq_state values are 0 or 1 on load There are no functional changes. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Acked-by: Isaku Yamahata <yamahata@valinux.co.jp>
2009-12-07msix: function mask supportMichael S. Tsirkin
Function mask is a mandatory feature in MSIX spec so not implementing it is a spec violation. Implement. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2009-12-07msix: macro rename for function mask supportMichael S. Tsirkin
rename ENABLE_OFFSET -> CONTROL_OFFSET, since same byte includes function mask. This is in preparation for function mask support. Signed-off-by: Michael S. Tsirkin <mst@redhat.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.

2009-12-06TCG: Mac OS X support for ppc64 targetAndreas Faerber
Darwin/ppc64 does not use function descriptors, adapt prologue and tcg_out_call accordingly. GPR2 is available for general use, so let's use it. http://developer.apple.com/mac/library/documentation/DeveloperTools/Conceptual/LowLevelABI/110-64-bit_PowerPC_Function_Calling_Conventions/64bitPowerPC.html v2: - Don't mark reserved GPR13 as callee-save. - Move tcg_out_b up. - Fix unused variable warning in prologue.

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. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
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. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
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. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
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. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2009-12-05S/390 host/target build system supportAlexander Graf
This patch makes configure aware of S390 hosts and guests. When not explicitly defined using --target-list= no S390 targets will be built though. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2009-12-05S/390 CPU fake emulationAlexander Graf
Because Qemu currently requires a TCG target to exist and there are quite some useful helpers here to lay the groundwork for out KVM target, let's create a stub TCG emulation target for S390X CPUs. This is required to make tcg happy. The emulation target itself won't work though. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2009-12-03Fix build for mingw32 on windows ($$ expansion)Stefan Weil
Make using mingw32 on windows fails when running grep "=y$$". The command is expanded to grep "=y$ and the missing " results in an error. I don't expect a file config-devices.mak with =y somewhere in the middle of a line (they are always at the end of the line), so simplifying the regular expression to =y seems to be permitted. This avoids problems with wrong expansion. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-12-03Fix build for mingw32 on windows ($@ in macro)Stefan Weil
Make using mingw32 on windows does not preserve $@ in macros when they are modified using this pattern: target: macro += something This behaviour results in an error when QEMU_CFLAGS containing "-MMD -MP -MT $@" is modified for compilation of source files which use SDL: $@ will expand to nothing, -MT no longer has the correct argument (it will take the next one from the command line) and the build will fail or run with a wrong command line. The problem is fixed by using a new macro QEMU_DGFLAGS which is not modified by a target rule. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-12-03Make -kernel for linux work with bochsbiosAlexander Graf
While trying to run -kernel with -bios pc-bios/pcbios.bin, I realized that I was actually writing data to %es, but only set up %ds to a 32-bit segment we want to write to. So at the end of the day the data hasn't actually been copied. Oops. So here's a fix to set ES instead of DS, which makes -kernel work with BOCHS bios again (and actually makes the code do the correct thing)!

2009-12-03Fix recently introduced bugs in -usbdevice hostMarkus Armbruster
Commit 26a9e82a has the following flaws: * It enabled DEBUG. * It referenced two properties by the wrong name in usb_host_device_open(), which crashes with "qdev_prop_set: property "USB Host Device.bus" not found". * It broke "-usbdevice host:auto:..." by calling parse_filter() incorrectly. * It broke parsing of "-usbdevice host:BUS.ADDR" and "-usbdevice host:VID:PRID" with a trivial pasto. * It broke wildcards in "-usbdevice host:auto:...". Before, the four filter components were stored as int, and the wildcard was encoded as -1. The faulty commit changed storage to uint32_t, and the wildcard encoding to 0. But it failed to update parse_filter() accordingly. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
