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.

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>
2009-12-03e1000: Fix warning from code reviewStefan Weil

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>

2009-12-03targe-ppc: Sync CPU state for KVMAlexander Graf

2009-12-03target-ppc: Get MMU state on register syncAlexander Graf
While x86 only needs to sync cr0-4 to know all about its MMU state and enable qemu to resolve virtual to physical addresses, we need to sync all of the segment registers on PPC to know which mapping we're in. So let's grab the segment register contents to be able to use the "x" monitor command and also enable the gdbstub to resolve virtual addresses.

2009-12-03qemu: cleanup unused macros in cirrusMichael S. Tsirkin

2009-12-03qemu: make cirrus init value pci spec compliantMichael S. Tsirkin
PCI memory should be disabled at reset, otherwise we might claim transactions at address 0. I/O should also be disabled, although for cirrus it is harmless to enable it as we do not have I/O bar. Note: bios fix needed for this patch to work was already applied: previously bios incorrently assumed that it does not need to enable i/o unless device has i/o bar. Signed-off-by: Michael S.

2009-12-03qcow2: Store exact backing format lengthKevin Wolf
Currently qcow2 unnecessarily rounds up the length of the backing format string to the next multiple of 8. At the same time, the array in BlockDriverState can only hold 15 characters, so in effect backing formats with 9 characters or more don't work (e.g. host_device).

rerror controls the action to be taken when an error occurs while accessing the guest image file. It corresponds to werror which already controls the action take for write errors.
