2012-09-25ivshmem: add 64bit optionGerd Hoffmann
This patch adds a "use64" property which will make the ivshmem driver register a 64bit memory bar when set, so you have something to play with when testing 64bit pci bits. It also allows to have quite big shared memory regions, like this: [root@fedora ~]# lspci -vs1:1 01:01.0 RAM memory: Red Hat, Inc Device 1110 Subsystem: Red Hat, Inc Device 1100 Physical Slot: 1-1 Flags: fast devsel Memory at fd400000 (32-bit, non-prefetchable) [disabled] [size=256] Memory at 8040000000 (64-bit, prefetchable) [size=1G] [ v5: rebase, update compat property for post-1.2 merge ] [ v4: rebase & adapt to latest master again ] [ v3: rebase & adapt to latest master ] [ v2: default to on as suggested by avi, turn off for pc-$old using compat property ] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Tested-by: Cam Macdonell <cam@cs.ualberta.ca> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-08-22virtio-blk: hide VIRTIO_BLK_F_CONFIG_WCE from old machine typesStefan Hajnoczi
QEMU has a policy of keeping a stable guest device ABI. When new guest device features are introduced they must not change hardware info seen by existing guests. This is important because operating systems or applications may "fingerprint" the hardware and refuse to run when the hardware changes. To always get the latest guest device ABI, run with x86 machine type "pc". This patch hides the new VIRTIO_BLK_F_CONFIG_WCE virtio feature bit from existing machine types. Only pc-1.2 and later will expose this feature by default. For more info on the VIRTIO_BLK_F_CONFIG_WCE feature bit, see: commit 13e3dce068773c971ff2f19d986378c55897c4a3 Author: Paolo Bonzini <pbonzini@redhat.com> Date: Thu Aug 9 16:07:19 2012 +0200 virtio-blk: support VIRTIO_BLK_F_CONFIG_WCE Also rename VIRTIO_BLK_F_WCACHE to VIRTIO_BLK_F_WCE for consistency with the spec.

2012-06-19Allow machines to configure the QEMU_VERSION that's exposed via hardwareCrístian Viana
QEMU exposes its version to the guest's hardware and in some cases that is wrong (e.g. Windows prints messages about driver updates when you switch the QEMU version). There is a new field now on the struct QEmuMachine, hw_version, which may contain the version that the specific machine should report. If that field is set, then that machine will report that version to the guest. Signed-off-by: Crístian Viana <vianac@linux.vnet.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-06-19Add PIIX4 properties to control PM system states.Gleb Natapov
This patch adds two things. First it allows QEMU to distinguish between regular powerdown and S4 powerdown. Later separate QMP notification will be added for S4 powerdown. Second it allows S3/S4 states to be disabled from QEMU command line. Some guests known to be broken with regards to power management, but allow to use it anyway. Using new properties management will be able to disable S3/S4 for such guests. Supported system state are passed to a firmware using new fw_cfg file. The file contains 6 byte array. Each byte represents one system state. If byte at offset X has its MSB set it means that system state X is supported and to enter it guest should use the value from lowest 3 bits.

2012-06-18qdev: Move bus properties to abstract superclassesPaolo Bonzini
In qdev, each bus in practice identified an abstract superclass, but this was mostly hidden. In QOM, instead, these abstract classes are explicit so we can move bus properties there. All bus property walks are removed, and all device property walks are changed to look along the class hierarchy instead. We would have duplicates if class A defines some properties and its subclass B does not define any, because class_b->props will be left equal to class_a->props. The solution here is to reintroduce the class_base_init TypeInfo callback, that was present in one of the early QOM versions but removed (on my request...) before committing. This breaks global bus properties, an obscure feature when used with the command-line which is actually useful and used when used by backwards-compatible machine types. So this patch also adjusts the global bus properties in hw/pc_piix.c to refer to the abstract class. Globals and other properties must be modified in the same patch to avoid complications related to initialization ordering.

2012-04-11virtio-pci: change virtio balloon PCI class codeDavid Gibson
Currently the virtio balloon device, when using the virtio-pci interface advertises itself with PCI class code MEMORY_RAM. This is wrong; the balloon is vaguely related to memory, but is nothing like a PCI memory device in the meaning of the class code, and this code is not required or suggested by the virtio PCI specification. Worse, this patch causes problems on the pseries machine, because the firmware, seeing this class code, advertises the device as memory in the device tree, and then a guest kernel bug causes it to see this "memory" before the real system memory, leading to a crash in early boot. This patch fixes the problem by removing the bogus PCI class code on the balloon device. The backwards compatibility PC machines get new compat properties so that they don't change.

2012-04-02qdev: add children before qdev_initPaolo Bonzini
We want the composition tree to to be in order by the time we call qdev_init, so that a single set of the toplevel realize property can propagate all the way down the composition tree. This is not the case so far. Unfortunately, this is incompatible with calling qdev_init in the constructor wrappers for devices, so for now we need to unattach some devices that are created through those wrappers. This will be fixed by removing qdev_init and instead setting the toplevel realize property after machine init.

This patch switches pc s3 suspend over to the new infrastructure. The cmos_s3 qemu_irq is killed, the new notifier is used instead. The xen hack goes away with that too, the hypercall can simply be done in a notifier function now. This patch also makes the guest actually stay suspended instead of leaving suspend instantly, so it is useful for more than just testing whenever the suspend/resume cycle actually works.

2012-01-19kvm: x86: Add user space part for in-kernel IOAPICJan Kiszka
This introduces the KVM-accelerated IOAPIC model 'kvm-ioapic' and extends the IRQ routing setup by the 0->2 redirection when needed. The kvm-ioapic model has a property that allows to define its GSI base for injecting interrupts into the kernel model. This will allow to disentangle PIC and IOAPIC pins for chipsets that support more sophisticated IRQ routes than the PIIX3. So far the base is kept at 0, i.e. PIC and IOAPIC share pins 0..15.

Introduce the alternative 'kvm-i8259' device model that exploits KVM in-kernel acceleration. The PIIX3 initialization code is furthermore extended by KVM specific IRQ route setup. GSI injection differs in KVM mode from the user space model. As we can dispatch ISA-range IRQs to both IOAPIC and PIC inside the kernel, we do not need to inject them separately. This is reflected by a KVM-specific GSI handler. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
