Starting with commit 1c380f94 dma transfers can actually fail. This patch makes ehci keep track of the busmaster bit in pci config space, by setting/clearing the dma_context pointer. Attempts to dma without context will result in raising HSE (Host System Error) interrupt and stopping the host controller. This patch fixes WinXP not booting with a usb stick attached to ehci. Root cause is seabios activating ehci so you can boot from the stick, and WinXP clearing the busmaster bit before resetting the host controller, leading to ehci actually trying dma while it is disabled.

Add a generic thread-pool. The code is roughly based on posix-aio-compat.c, with some changes, especially the following: - use QemuSemaphore instead of QemuCond; - separate the state of the thread from the return code of the worker function. The return code is totally opaque for the thread pool; - do not busy wait when doing cancellation. A more generic threadpool (but still specific to I/O so that in the future it can use special scheduling classes or PI mutexes) can have many uses: it allows more flexibility in raw-posix.c and can more easily be extended to Win32, and it will also be used to do an msync of the persistent bitmap.

According to the spec a guest can unlink a qh, and then as soon as frindex has changed by 1 since the unlink, assume it is idle and re-use it. However for various reasons, we cannot simply consider a qh as unlinked if we've not seen it for 1 frame. This means that it is possible for a guest to re-use / restart the queue while we still see its old state. This patch adds a safety check for this, and "early" retires queues when they were changed by the guest.

This patch adds the implementation of a new job that mirrors a disk to a new image while letting the guest continue using the old image. The target is treated as a "black box" and data is copied from the source to the target in the background. This can be used for several purposes, including storage migration, continuous replication, and observation of the guest I/O in an external program. It is also a first step in replacing the inefficient block migration code that is part of QEMU. The job is possibly never-ending, but it is logically structured into two phases: 1) copy all data as fast as possible until the target first gets in sync with the source; 2) keep target in sync and ensure that reopening to the target gets a correct (full) copy of the source data. The second phase is indicated by the progress in "info block-jobs" reporting the current offset to be equal to the length of the file. When the job is cancelled in the second phase, QEMU will run the job until the source is clean and quiescent, then it will report successful completion of the job. In other words, the BLOCK_JOB_CANCELLED event means that the target may _not_ be consistent with a past state of the source; the BLOCK_JOB_COMPLETED event means that the target is consistent with a past state of the source. (Note that it could already happen that management lost the race against QEMU and got a completion event instead of cancellation). It is not yet possible to complete the job and switch over to the target disk. The next patches will fix this and add many refinements to the basic idea introduced here. These include improved error management, some tunable knobs and performance optimizations. Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

While streaming can be dropped as soon as it progressed through the whole image, mirroring needs to be completed manually for two reasons: 1) so that management knows exactly when the VM switches to the target; 2) because for other use cases such as replication, we may leave the operation running for the whole life of the virtual machine. Add a new block job command that manually completes background operations. Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

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.

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: NAlon Levy <alevy@redhat.com> Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

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.

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.

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.

$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.
