2010-04-01tap: add vhost/vhostfd optionsMichael S. Tsirkin
This adds vhost binary option to tap, to enable vhost net accelerator. Default is off for now, we'll be able to make default on long term when we know it's stable. vhostfd option can be used by management, to pass in the fd. Assigning vhostfd implies vhost=on.

2010-04-01vhost: vhost net supportMichael S. Tsirkin
This adds vhost net device support in qemu. Will be tied to tap device and virtio by following patches. Raw backend is currently missing, will be worked on/submitted separately. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-04-01virtio-pci: fill in notifier supportMichael S. Tsirkin
Support host/guest notifiers in virtio-pci. The last one only with kvm, that's okay because vhost relies on kvm anyway. Note on kvm usage: kvm ioeventfd API is implemented on non-kvm systems as well, this is the reason we don't need if (kvm_enabled()) around it. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-04-01virtio: move typedef to qemu-commonMichael S. Tsirkin
make it possible to use type without header include, simplifying header dependencies. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-04-01virtio: add set_status callbackMichael S. Tsirkin
vhost net backend needs to be notified when frontend status changes. Add a callback, similar to set_features. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-04-01virtio: notifier support + APIs for queue fieldsMichael S. Tsirkin
vhost needs physical addresses for ring and other queue fields, so add APIs for these. In particular, add binding API to set host/guest notifiers. Will be used by vhost. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-04-01notifier: event notifier implementationMichael S. Tsirkin
event notifiers are slightly generalized eventfd descriptors. Current implementation depends on eventfd because vhost is the only user, and vhost depends on eventfd anyway, but a stub is provided for non-eventfd case. We'll be able to further generalize this when another user comes along and we see how to best do this. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-04-01kvm: add API to set ioeventfdMichael S. Tsirkin
Comment on kvm usage: rather than require users to do if (kvm_enabled()) and/or ifdefs, this patch adds an API that, internally, is defined to stub function on non-kvm build, and checks kvm_enabled for non-kvm run. While rest of qemu code still uses if (kvm_enabled()), I think this approach is cleaner, and we should convert rest of code to it long term. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-04-01tap: add interface to get device fdMichael S. Tsirkin

2010-04-01virtio-pci: compile per-targetAnthony Liguori
With vhost, virtio-pci needs to include kvm.h and kvm.h needs to be built per-target. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-04-01Fix -enable-kvmAnthony Liguori
Make vl.o compiled per target and fix a thinko in hw/acpi.c. It's not trivial to make kvm.h consumable by compiled-once files. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-03-31Restore terminal monitor attributes - additionShahar Havivi
Patch 2d753894c7553d6a05e8fdbed5f4704398919a35 was missing this check, when running monitor as /dev/tty and other serial device, i.e: qemu -monitor /dev/tty -serial /dev/pts/1 Without this patch any serial device will override the monitor stored attributes. (monitor is called in main() before any serial device). Signed-off-by: Shahar Havivi <shaharh@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-03-31Don't check for bus master for old guestsAlexander Graf
Older Linux guests don't activate the bus master enable bit. So for those we can just try to be clever and track if they set the DEVICE_OK bit even though bus mastering is still disabled. Under that condition we can disable the windows safety check. With that logic in place both guests should work just fine. Without PCI hotplug breaks virtio-net in Linux < 2.6.34 guests.

2010-03-31usb: class specific interface requestsMax Reitz
Mass Storage Reset and Get Max LUN are class specific requests, but they were not marked as such in hw/usb-msd.c, moved therefore ClassInterfaceRequest and ClassInterfaceOutRequest from hw/usb-net.c to hw/usb.h. Furthermore there was a problem in hw/usb-ohci.c when using DEBUG concerning systems where size_t is a 32 bit integer (printf resulted in a segmentation fault).

2010-03-30Get bsd-user host page protection code working on FreeBSD hostsJuergen Lock
Use kinfo_getvmmap(3) on FeeBSD >= 7.x and /compat/linux/proc on older FreeBSD. (kinfo_getvmmap is preferred since /compat/linux/proc is usually only mounted on hosts also using the Linuxolator.) This patch is a bit hacky because the includes needed for kinfo_getvmmap conflict with other definitions in exec.c by default so I had to `trick around' a little, but I built the result in FreeBSD 6.4-stable and 7.2-stable tbs and on 8-stable on the host so the hacks at least should be stable. (If this is a problem maybe we could also move the kinfo_getvmmap invocations into a seperate source file but that would be more work...)

2010-03-28linux-user/ppc: use the Linux register layoutRob Landley
The dynamic linker converts the Linux layout to the AIX layout and is reentrant so it won't do it a second time if it's already been converted. In short it work just fine with either register layout. OTOH, statically linked binaries expect a Linux layout. Remove code converting the Linux layout to AIX layout so that all binaries are presented the Linux Layout.
