When the host page size is bigger that the target one, unprotecting a page should: - mark all the target pages corresponding to the host page as writable - invalidate all tb corresponding to the host page (and not the target page) Signed-off-by: NAurelien Jarno <aurelien@aurel32.net>

ia64 has some strangenesses that need to be workaround: - it has a __clone2() syscall instead of the using clone() one, with different arguments, and which is not declared in the usual headers. - ucontext.uc_sigmask is declared with type long int, while it is actually of type sigset_t. - uc_mcontext, uc_sigmask, uc_stack, uc_link are declared using #define, which clashes with the target_ucontext fields. Change their names to tuc_*, as already done for some target architectures.

This connects virtio-net to vhost net backend. The code is structured in a way analogous to what we have with vnet header capability in tap. We start/stop backend on driver start/stop as well as on save and vm start (for migration). Signed-off-by: NMichael S. Tsirkin <mst@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

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.

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: NMichael S.

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: NMichael S.

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: NMichael S.

Patch 2d753894 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.

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.

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).

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...)
