2012-01-26virtio-blk: add virtio_blk_handle_read trace eventStefan Hajnoczi
There already exists a virtio_blk_handle_write trace event as well as completion events. Add the virtio_blk_handle_read event so it's easy to trace virtio-blk requests for both read and write operations.

2012-01-26block: make copy-on-read a per-request flagStefan Hajnoczi
Previously copy-on-read could only be enabled for all requests to a block device. This means requests coming from the guest as well as QEMU's internal requests would perform copy-on-read when enabled. For image streaming we want to support finer-grained behavior than just populating the image file from its backing image. Image streaming supports partial streaming where a common backing image is preserved. In this case guest requests should not perform copy-on-read because they would indiscriminately copy data which should be left in a backing image from the backing chain. Introduce a per-request flag for copy-on-read so that a block device can process both regular and copy-on-read requests. Overlapping reads and writes still need to be serialized for correctness when copy-on-read is happening, so add an in-flight reference count to track this.

2011-10-28scsi: do not call transfer_data after canceling a requestPaolo Bonzini
Otherwise, if cancellation is "faked" by the AIO layer and goes through qemu_aio_flush, the whole request is completed synchronously during scsi_req_cancel. Using the enqueued flag would work here, but not in the next patches, so I'm introducing a new io_canceled flag. That's because scsi_req_data is a synchronous callback and the enqueued flag might be reset by the time it returns. scsi-disk cannot unref the request until after calling scsi_req_data.

2011-10-28iSCSI block driverRonnie Sahlberg
This provides built-in support for iSCSI to QEMU. This has the advantage that the iSCSI devices need not be made visible to the host, which is useful if you have very many virtual machines and very many iscsi devices. It also has the benefit that non-root users of QEMU can access iSCSI devices across the network without requiring root privilege on the host. This driver interfaces with the multiplatform posix library for iscsi initiator/client access to iscsi devices hosted at git://github.com/sahlberg/libiscsi.git The patch adds the driver to interface with the iscsi library. It also updated the configure script to * by default, probe is libiscsi is available and if so, build qemu against libiscsi. * --enable-libiscsi Force a build against libiscsi. If libiscsi is not available the build will fail. * --disable-libiscsi Do not link against libiscsi, even if it is available. When linked with libiscsi, qemu gains support to access iscsi resources such as disks and cdrom directly, without having to make the devices visible to the host. You can specify devices using a iscsi url of the form : iscsi://[<username>[:<password>@]]<host>[:<port]/<target-iqn-name>/<lun> When using authentication, the password can optionally be set with LIBISCSI_CHAP_PASSWORD="password" to avoid it showing up in the process list Signed-off-by: Ronnie Sahlberg <ronniesahlberg@gmail.com> Reviewed-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2011-10-15hw/9pfs: Introduce tracing for 9p pdu handlersHarsh Prateek Bora
Plan is to replace the existing debug infrastructure with Qemu tracing infrastructure so that user can dynamically enable/disable trace events and therefore a meaningful trace log can be generated which can be further filtered using an analysis script. Note: Because of current simpletrace limitations, the trace events are logging at max 6 args, however, once the more args are supported, we can change trace events to log more info as well. Also, This initial patch only provides a replacement for existing debug infra. More trace events to be added later for newly added handlers and sub-routines.

2011-09-07usb: claim port at device initialization time.Gerd Hoffmann
This patch makes qemu assign a port when creating the device, not when attaching it. For most usb devices this isn't a noticable difference because they are in attached state all the time. The change affects usb-host devices which live in detached state while the real device is unplugged from the host. They have a fixed port assigned all the time now instead of getting grabbing one on attach and releasing it at detach, i.e. they stop floating around at the usb bus. The change also allows to simplify usb-hub. It doesn't need the handle_attach() callback any more to configure the downstream ports. This can be done at device initialitation time now. The changed initialization order (first grab upstream port, then register downstream ports) also fixes some icky corner cases. For example it is not possible any more to plug the hub into one of its own downstream ports. The usb host adapters must care too. USBPort->dev being non-NULL doesn't imply any more the device is in attached state. The host adapters must additionally check the USBPort->dev->attached flag.

This patch adds code to do minimal siTD handling, which is basically just following the next pointer. This is good enougth to handle the inactive siTDs used by FreeBSD.

2011-09-07usb-host: claim portGerd Hoffmann
