2010-04-02hw/r2d: add a USB keyboardAurelien Jarno
The R2D board does not have a PS/2 port, and only support a keyboard on the USB bus. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-04-02usb-bus: fix no paramsTeLeMan
After commit 702f3e0fb52c124c07f215426eeadb70a716643f, the params is nerver NULL. It should check *params instead of params to determine whether the params is empty. Signed-off-by: TeLeMan <geleman@gmail.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-04-01virtio-net: vhost net supportMichael S. Tsirkin
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: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
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.

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.

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).

2010-03-27balloon: Fix overflow when reporting actual memory sizeAdam Litke
Beginning with its introduction, the virtio balloon has had an overflow error that causes 'info balloon' to misreport the actual memory size when the balloon itself becomes larger than 4G. Use a cast when converting dev->actual from pages to kB to prevent overflows. Before: (qemu) info balloon balloon: actual=5120 (qemu) balloon 1025 (qemu) info balloon balloon: actual=1025 (qemu) balloon 1024 (qemu) info balloon balloon: actual=5120 After: (qemu) info balloon balloon: actual=5120 (qemu) balloon 1025 (qemu) info balloon balloon: actual=1025 (qemu) balloon 1024 (qemu) info balloon balloon: actual=1024 Signed-off-by: Adam Litke <agl@us.ibm.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-03-19Convert atexit users to exit_notifierAnthony Liguori
All of these users have global state so we really don't see a benefit from exit_notifier. However, using exit_notifier means that there's one less justification for having global state in the first place. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-03-19Rewrite mouse handlers to use QTAILQ and to have an activation functionAnthony Liguori
And convert usb-hid to use it (to avoid regression with bisection) Right now, when we do info mice and we've added a usb tablet, we don't see it until the guest starts using the tablet. We implement this behavior in order to provide a means to delay registration of a mouse handler since we treat the last registered handler as the current handler. This is a usability problem though as we would like to give the user feedback that they've either 1) not added an absolute device 2) there is an absolute device but the guest isn't using it 3) we have an absolute device and it's active. By using QTAILQ and having an explicit activation function that moves the handler to the front of the queue, we can implement the same semantics as before with respect to automatically switching to usb tablet while providing the user with a whole lot more information.

2010-03-17balloon: Do not save VM state wrt asynchronous virtio operationsAdam Litke
When working with the VM state (for loadvm/savevm and migration), it is not valid to load and store pointers since the validity of those pointers cannot be assured in the new qemu address space. Therefore, virtio_balloon_save() and virtio_balloon_load() must not handle the stats-related fields in struct VirtIOBalloon. If a memory stats request is in-flight at the time of a migration or savevm, the request will not complete and should be resubmitted once migration or loadvm completes. Note that this extremely small race window can only be triggered using QMP so it is not possible to hang the user monitor.

2010-03-17block: add logical_block_size propertyChristoph Hellwig
Add a logical block size attribute as various guest side tools only increase the filesystem sector size based on it, not the advisory physical block size. For scsi we already have support for a different logical block size in place for CDROMs that we can built upon. Only my recent block device characteristics VPD page needs some fixups. Note that we leave the logial block size for CDROMs hardcoded as the 2k value is expected for it in general. For virtio-blk we already have a feature flag claiming to support a variable logical block size that was added for the s390 kuli hypervisor. Interestingly it does not actually change the units in which the protocol works, which is still fixed at 512 bytes, but only communicates a different minimum I/O granularity. So all we need to do in virtio is to add a trap for unaligned I/O and round down the device size to the next multiple of the logical block size. IDE does not support any other logical block size than 512 bytes. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
