2009-07-12target-ppc: fix typo in _cpu_ppc_load_decrTristan Gingold
Use parameter 'next' to fix the hdecr case. Also pass 'next' by value instead of pointer (more easy to read and no performance issue for an always_inline function). Signed-off-by: Tristan Gingold <gingold@adacore.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2009-07-10qemu/virtio: mark msi vectors used on loadMichael S. Tsirkin
Usage of msi vectors is controlled by the guest and so needs to be restored on load. Do this for msi vectors used by the virtio device. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-10qemu/msi: missing bracesMichael S. Tsirkin
MSIX present bit is tested incorrectly, and only happens to work because the bit we are testing is 0x1. Add braces to fix this. Reported-by: Blue Swirl <blauwirbel@gmail.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-10qemu/msi: clean used vectors state on loadMichael S. Tsirkin
Clean up msix vector usage state on load. Since guest might have control over it through the device, the device will have to load this state from file. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-10usb-ohci: Fix endianness issueMichael Buesch

2009-07-09Unregister savevm callback in eeprom93xx_free()Mark McLoughlin
Otherwise if you hot remove an eepro100 NIC and then migrate, you get: Unknown savevm section or instance 'eeprom' 0 on the destination side. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-07-09Don't leak VLANClientState on PCI hot removeMark McLoughlin
destroy_nic() requires that NICInfo::private by a PCIDevice pointer, but then goes on to require that the same pointer matches VLANClientState::opaque. That is no longer the case for virtio-net since qdev and wasn't previously the case for rtl8139, ne2k_pci or eepro100. Make the situation a lot more clear by maintaining a VLANClientState pointer in NICInfo. Signed-off-by: Mark McLoughlin <markmc@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-07-09qdev/pci: misc fixes.Gerd Hoffmann
* fix secondary bus setup. * use base->name instead of "FIXME" for device name. Yes, the device name is redundant. Only for drivers converted to qdev already though. Once all drivers are converted we can and should kill it. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2009-07-09qdev: remove DeviceTypeGerd Hoffmann
The only purpose DeviceType serves is creating a linked list of DeviceInfo structs. This removes DeviceType and add a next field to DeviceInfo instead, so the DeviceInfo structs can be changed that way. Elimitates a pointless extra level of indirection. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2009-07-09qdev: replace bus_type enum with bus_info struct.Gerd Hoffmann
BusInfo is filled with name and size (pretty much like I did for DeviceInfo as well). There is also a function pointer to print bus-specific device information to the monitor. sysbus is hooked up there, I've also added a print function for PCI. Device creation is slightly modified as well: The device type search loop now also checks the bus type while scanning the list instead of complaining thereafter in case of a mismatch. This effectively gives each bus a private namespace for device names. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Paul Brook <paul@codesourcery.com>
2009-07-09qdev: update pci device registration.Gerd Hoffmann
Makes pci_qdev_register take a PCIDeviceInfo struct instead of a bunch of parameters. Also adds config_read and config_write callbacks to PCIDeviceInfo, so drivers needing these can be converted to the qdev device API too. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2009-06-29Replace -no-virtio-balloon by -balloonMarkus Armbruster
We want to do (at least) two things to the virtio-balloon device: suppress it, and control its PCI address. Option -no-virtio-balloon lets us do only the former. To get the latter, replace -no-virtio-balloon with -balloon none disable balloon device -balloon virtio[,addr=str] enable virtio balloon device (default) Syntax suggested by Anthony Liguori.

2009-06-29x86: Factor out pc_new_cpuJan Kiszka
At this point, this refactoring looks like overkill. But we will need it for CPU hotplugging, and qemu-kvm already carries it. Merging it early would help qemu-kvm when rebasing against upstream. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-29Revert "Introduce reset notifier order"Jan Kiszka
This reverts commit 8217606e6edb49591b4a6fd5a0d1229cebe470a9 (and updates later added users of qemu_register_reset), we solved the problem it originally addressed less invasively. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-06-29kvm: Rework VCPU synchronizationJan Kiszka
During startup and after reset we have to synchronize user space to the in-kernel KVM state. Namely, we need to transfer the VCPU registers when they change due to VCPU as well as APIC reset. This patch refactors the required hooks so that kvm_init_vcpu registers its own per-VCPU reset handler and adds a cpu_synchronize_state to the APIC reset. That way we no longer depend on the new reset order (and can drop this disliked interface again) and we can even drop a KVM hook in main().

2009-06-29monitor: Drop pci_addr prefix from hotplug commandsJan Kiszka
The "pci_addr=" prefix currently required by pci_add/remove and drive_add has no practical use. Drop it, but still silently accept it for backward compatibility. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-29Multiboot support v5Alexander Graf
This patch implements support for Multiboot on x86 for -kernel. Multiboot is a "new" approach to get rid of different bootloaders, providing a unified interface for the kernel. It supports command line options and kernel modules. The two probably best known projects using multiboot are Xen and GNU Hurd. This implementation should be mostly feature-complete. It is missing VBE extensions, but as no system uses them currently it does not really hurt. To use multiboot, specify the kernel as -kernel option. Modules should be given as -initrd options, seperated by a comma (,). -append also works. Please bear in mind that grub also does gzip decompression, which qemu does not do yet. To run existing images, please ungzip them first. The guest multiboot loader code is implemented as option rom using int 19. Parts of the work are based on efforts by Rene Rebe, who originally ported my code to int 19. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-29Expose fw_cfg v2Alexander Graf
Multiboot passes options to the option rom using the fw_cfg device. Right now, that device is local to the bochs_bios_init function. Let's change that and expose it, so everyone may put data in there. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-29Change bochs bios init orderAlexander Graf
For multiboot support, we need bochs_bios_init to happen before load_linux, so we get the fw_cfg device. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-06-29net: Provide VLAN client lookup helperJan Kiszka

2009-06-24Add serial number support for virtio_blkjohn cooper
[brought forward to current qemu-kvm.git] This patch implements the missing qemu logic to interpret a '-drive .. serial=XYZ ..' flag for a virtio_blk device. The serial number string is contained in a skeletal IDENTIFY DEVICE data structure and this structure is made available to the guest virtio_blk driver via pci i/o region 0.

2009-06-24qemu/net: flag to control the number of vectors a nic hasMichael S. Tsirkin
