2014-09-30Merge remote-tracking branch 'remotes/bonzini/tags/for-upstream' into stagingPeter Maydell
This update brings dataplane to virtio-scsi (NOT yet 100% thread-safe, though, which makes it really, really experimental. It also brings asynchronous cancellation to the SCSI subsystem and implements it in virtio-scsi. This is a pretty important feature. Almost all the work here was done by Fam Zheng. I also included the virtio refcount fixes from Gonglei, because they had a small conflict with virtio-scsi dataplane.

2014-09-30virtio-scsi: Handle TMF request cancellation asynchronouslyFam Zheng
For VIRTIO_SCSI_T_TMF_ABORT_TASK and VIRTIO_SCSI_T_TMF_ABORT_TASK_SET, use scsi_req_cancel_async to start the cancellation. Because each tmf command may cancel multiple requests, we need to use a counter to track the number of remaining requests we still need to wait for.

2014-09-30scsi: Introduce scsi_req_cancel_asyncFam Zheng
Devices will call this function to start an asynchronous cancellation. The bus->info->cancel will be called after the request is canceled. Devices will probably need to track a separate TMF request that triggers this cancellation, and wait until the cancellation is done before completing it. So we store a notifier list in SCSIRequest and in scsi_req_cancel_complete we notify them. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2014-09-30scsi: Drop SCSIReqOps.cancel_ioFam Zheng
The only two implementations are identical to each other, with nothing specific to device: they only call bdrv_aio_cancel with the SCSIRequest.aiocb. Let's move it to scsi-bus. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-09-30scsi: Unify request unref in scsi_req_cancelFam Zheng
Before, scsi_req_cancel will take ownership of the canceled request and unref it. We did this because we didn't know whether AIO CB will be called or not during the cancelling, so we set the io_canceled flag before calling it, and skip unref in the potentially called callbacks, which is not very nice. Now, bdrv_aio_cancel has a stricter contract that the completion callbacks are always called, so we can remove the checks of req->io_canceled and just unref it in callbacks. It will also make implementing asynchronous cancellation easier. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-09-30scsi-generic: Handle canceled request in scsi_command_completeFam Zheng
Now that we always called the cb in bdrv_aio_cancel, let's make scsi-generic callbacks check io_canceled flag similarly to scsi-disk. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-09-30scsi: Drop scsi_req_abortFam Zheng
The only user of this function is spapr_vscsi.c. We can convert to scsi_req_cancel plus adding a check in vscsi_request_cancelled.

2014-09-30virtio-scsi: Hook up with dataplaneFam Zheng
This enables the virtio-scsi-dataplane code by setting the iothread in virtio-scsi device, and makes any function that is called by back from dataplane to cooperate with the caller: they need to be vring/iothread aware when handling the requests and using scsi devices on the bus.

2014-09-30virtio-scsi-dataplane: Code to run virtio-scsi on iothreadFam Zheng
This implements the core part of dataplane feature of virtio-scsi. A few fields are added in VirtIOSCSICommon to maintain the dataplane status. These fields are managed by a new source file: virtio-scsi-dataplane.c. Most code in this file will run on an iothread, unless otherwise commented as in a global mutex context, such as those functions to start, stop and setting the iothread property. Upon start, we set up guest/host event notifiers, in a same way as virtio-blk does. The handlers then pop request from vring and call into virtio-scsi.c functions to process it. So we need to make sure make all those called functions work with iothread, too. Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2014-09-26virtio-balloon: fix integer overflow in memory stats featureLuiz Capitulino
When a QMP client changes the polling interval time by setting the guest-stats-polling-interval property, the interval value is stored and manipulated as an int64_t variable. However, the balloon_stats_change_timer() function, which is used to set the actual timer with the interval value, takes an int instead, causing an overflow for big interval values. This commit fix this bug by changing balloon_stats_change_timer() to take an int64_t and also it limits the polling interval value to UINT_MAX to avoid other kinds of overflow.

2014-09-23tcx: Implement hardware accelerationMark Cave-Ayland
The S24/TCX framebuffer is a mildly accelerated video card with blitter, stippler and hardware cursor. * Solaris and NetBSD 6.x use all the hardware acceleration features * The Xorg driver (used by Linux) can use the hardware cursor only This patch implements hardware acceleration in both 8 bit and 24 bit modes. It is based on the NetBSD driver sources and from tests with Solaris. Signed-off-by: Olivier Danet <odanet@caramail.com> Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>
