2012-09-28qmp: add block-job-pause and block-job-resumePaolo Bonzini
Add QMP commands matching the functionality. Paused jobs cannot be canceled without first resuming them. This ensures that I/O errors are never missed by management. However, an optional force argument can be specified to allow that.

2012-09-28block: add live block commit functionalityJeff Cody
This adds the live commit coroutine. This iteration focuses on the commit only below the active layer, and not the active layer itself. The behaviour is similar to block streaming; the sectors are walked through, and anything that exists above 'base' is committed back down into base. At the end, intermediate images are deleted, and the chain stitched together. Images are restored to their original open flags upon completion.

2012-09-13hw/qxl: support client monitor configuration via deviceAlon Levy
Until now we used only the agent to change the monitor count and each monitor resolution. This patch introduces the qemu part of using the device as the mediator instead of the agent via virtio-serial. Spice (>=0.11.5) calls the new QXLInterface::client_monitors_config, which returns wether the interrupt is enabled, and if so and given a non NULL monitors config will generate an interrupt QXL_INTERRUPT_CLIENT_MONITORS_CONFIG with crc checksum for the guest to verify a second call hasn't interfered. The maximal number of monitors is limited on the QXLRom to 64. Signed-off-by: Alon Levy <alevy@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-09-12ehci: switch to new-style memory opsGerd Hoffmann
Also register different memory regions for capabilities, operational registers and port status registers. Create separate tracepoints for operational regs and port status regs. Ditch a bunch of sanity checks because the memory core will do this for us now. Offloading the byte, word and dword access handling to the memory core also has the side effect of fixing ehci register access on bigendian hosts.

2012-09-11xhci: drop bufferingGerd Hoffmann
This patch splits the xhci_xfer_data function into three. The xhci_xfer_data function used to do does two things: (1) copy transfer data between guest memory and a temporary buffer. (2) report transfer results to the guest using events. Now we three functions to handle this: (1) xhci_xfer_map creates a scatter list for the transfer and uses that (instead of the temporary buffer) to build a USBPacket. (2) xhci_xfer_unmap undoes the mapping. (3) xhci_xfer_report sends out events. The patch also fixes reporting of transaction errors which must be reported unconditinally, not only in case the guest asks for it using the ISP flag.

2012-08-15pseries: Add PCI MSI/MSI-X supportAlexey Kardashevskiy
This patch implements MSI and MSI-X support for the pseries PCI host bridge. To do this it adds: * A "config_space_address to msi_table" map, since the MSI RTAS calls take a PCI config space address as an identifier. * A MSIX memory region to catch msi_notify()/msix_notiry() from virtio-pci and pass them to the guest via qemu_irq_pulse(). * RTAS call "ibm,change-msi" which sets up MSI vectors for a device. Note that this call may configure and return lesser number of vectors than requested. * RTAS call "ibm,query-interrupt-source-number" which translates MSI vector to interrupt controller (XICS) IRQ number.

2012-07-12usb: add usb attached scsi emulationGerd Hoffmann
$subject says all. First cut. It's a pure UAS (usb attached scsi) emulation, without BOT (bulk-only transport) compatibility. If your guest can't handle it use usb-storage instead. The emulation works like any other scsi hba emulation (eps, lsi, virtio, megasas, ...). It provides just the HBA where you can attach scsi devices as you like using '-device'. A single scsi target with up to 256 luns is supported. For now only usb 2.0 transport is supported. This will change in the future though as I plan to use this as playground when codeing up & testing usb 3.0 transport and streams support in the qemu usb core and the xhci emulation. No migration support yet. I'm planning to add usb 3.0 support first as this probably requires saving additional state. Special thanks go to Paolo for bringing the qemu scsi emulation into shape, so this can be added nicely without having to touch a single line of scsi code.

2012-06-15Add rate limiting of RTC_CHANGE, BALLOON_CHANGE & WATCHDOG eventsDaniel P. Berrange
Allow certain event types to be rate limited to avoid flooding monitor clients. The monitor_protocol_event() method is changed such that instead of immediately emitting the event to Monitor instances, it will call a new monitor_protocol_event_queue() method. This will check to see if the rate limit for the event has been exceeded, and if so schedule a timer to wakeup at the end of the rate limit period. If further events arrive before the timer fires, the previously queued event will be discarded in favour of the new event. The event will eventually be emitted when the timer fires. This logic is applied to RTC_CHANGE, BALLOON_CHANGE & WATCHDOG events, since the data associated with these events is stateless * monitor.c: Add support for rate limiting * monitor.h: Define monitor_global_init for one-time setup tasks * vl.c: Invoke monitor_global_init * trace-events: Add hooks for monitor event tracing Signed-off-by: Daniel P.
