2016-02-29spice/gl: Enable dmabuf only for spice >= 0.13.1Michal Privoznik
After 474114b7 the dmabuf feature is enabled whenever spice greater than or equal to spice 0.13.0 is found. This is because two new functions are required: spice_qxl_gl_scanout and spice_qxl_gl_draw_async. These were, however, introduce in 0.13.1 release. Well, technically they haven't been released yet, but for sure they are not going to be part of 0.13.0 release (for the ABI stability sake).

2016-02-28xics: report errors with the QEMU Error APIGreg Kurz
Using the return value to report errors is error prone: - xics_alloc() returns -1 on error but spapr_vio_busdev_realize() errors on 0 - xics_alloc_block() returns the unclear value of ics->offset - 1 on error but both rtas_ibm_change_msi() and spapr_phb_realize() error on 0 This patch adds an errp argument to xics_alloc() and xics_alloc_block() to report errors. The return value of these functions is a valid IRQ number if errp is NULL. It is undefined otherwise. The corresponding error traces get promotted to error messages. Note that the "can't allocate IRQ" error message in spapr_vio_busdev_realize() also moves to xics_alloc(). Similar error message consolidation isn't really applicable to xics_alloc_block() because callers have extra context (device config address, MSI or MSIX). This fixes the issues mentioned above.

2016-02-28migration: allow machine to enforce configuration section migrationGreg Kurz
Migration of pseries-2.3 doesn't have configuration section. Unfortunately, QEMU 2.4/2.4.1/2.5 are buggy and always stream and expect the configuration section, and break migration both ways. This patch introduces a property which allows to enforce a configuration section for machines who don't have one. It can be set at startup: -machine enforce-config-section=on or later from the QEMU monitor: qom-set /machine enforce-config-section on It is up to the tooling to set or unset this property according to the version of the QEMU at the other end of the pipe.

2016-02-26migration (ordinary): move bdrv_invalidate_cache_all of of coroutine contextDenis V. Lunev
There is a possibility to hit an assert in qcow2_get_specific_info that s->qcow_version is undefined. This happens when VM in starting from suspended state, i.e. it processes incoming migration, and in the same time 'info block' is called. The problem is that qcow2_invalidate_cache() closes the image and memset()s BDRVQcowState in the middle. The patch moves processing of bdrv_invalidate_cache_all out of coroutine context for standard migration to avoid that. Signed-off-by: Denis V.

2016-02-26sdhci: add quirk property for card insert interrupt status on Raspberry PiAndrew Baumann
This quirk is a workaround for the following hardware behaviour, on which UEFI (specifically, the bootloader for Windows on Pi2) depends: 1. at boot with an SD card present, the interrupt status/enable registers are initially zero 2. upon enabling it in the interrupt enable register, the card insert bit in the interrupt status register is immediately set 3. after a subsequent controller reset, the card insert interrupt does not fire, even if enabled in the interrupt enable register Signed-off-by: Andrew Baumann <Andrew.Baumann@microsoft.com> Message-id: 1456436130-7048-3-git-send-email-Andrew.Baumann@microsoft.com Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

interrupts" This reverts commit 723697551a7e926abe7d3c7f2966012b8075143d. This change was poorly tested on my part. It squelched card insertion interrupts on reset, but that was not necessary because sdhci_reset() clears all the registers (via the call to memset), so the subsequent sdhci_insert_eject_cb() call never sees the card insert interrupt enabled. However, not calling the insert_eject_cb results in prnsts remaining 0, when it actually needs to be updated to indicate card presence and R/O status.

2016-02-26fw_cfg: unbreak migration compatibility for 2.4 and earlier machinesLaszlo Ersek
When I reviewed Marc's fw_cfg DMA patches, I completely missed that the way we set dma_enabled would break migration. Gerd explained the right way (see reference below): dma_enabled should be set to true by default, and only true->false transitions should be possible: - when the user requests that with -global fw_cfg_mem.dma_enabled=off or -global fw_cfg_io.dma_enabled=off as appropriate for the platform, - when HW_COMPAT_2_4 dictates it, - when board code initializes fw_cfg without requesting DMA support.

2016-02-25virtio-blk: fix "disabled data plane" modePaolo Bonzini
In disabled mode, virtio-blk dataplane seems to be enabled, but flow actually goes through the normal virtio path. This patch simplifies a bit the handling of disabled mode. In disabled mode, virtio_blk_handle_output might be called even if s->dataplane is not NULL. This is a bit tricky, because the current check for s->dataplane will always trigger, causing a continuous stream of calls to virtio_blk_data_plane_start. Unfortunately, these calls will not do anything. To fix this, set the "started" flag even in disabled mode, and skip virtio_blk_data_plane_start if the started flag is true. The resulting changes also prepare the code for the next patch, were virtio-blk dataplane will reuse the same virtio_blk_handle_output function as "regular" virtio-blk. Because struct VirtIOBlockDataPlane is opaque in virtio-blk.c, we have to move s->dataplane->started inside struct VirtIOBlock.

2016-02-23Postcopy+spice: Pass spice migration data earlierDr. David Alan Gilbert
Spice hooks the migration status changes to figure out when to transmit information to the new spice server; but the migration status in postcopy doesn't quite fit - the destination starts running before the end of the source migration. It's not a case of hanging off the migration status change to postcopy-active either, since that happens before we stop the guest CPU. Fix it by sending a notify just after sending the device state, and adding a flag that can be tested by the notify receiver.

2016-02-23spice: add opengl/virgl/dmabuf supportGerd Hoffmann
This adds support for dma-buf passing to spice. This makes virtio-gpu with 3d acceleration work with spice. Workflow: * virglrenderer renders the guest command stream into a texture. * qemu exports the texture as dma-buf and passes on that dma-buf to spice-server. * spice-server passes the dma-buf to spice-client, using unix socket file descriptor passing. * spice-client asks the window systems composer to render the dma-buf to the screen. Requires cutting edge spice (server) and spice-gtk (client) builds, from git master branch. Also requires libvirt managing your qemu instance, and using "virt-viewer --attach $guest". libvirt will connect spice-server and spice-client using unix sockets instead of tcp sockets then, which is required for file descriptor passing. Works for the local case (spice server and client on the same machine) only. Supporting remote too is planned (by feeding the dma-bufs into gpu-assisted video encoder), but not there yet. gl mode is turned off by default, use "-spice gl=on,$otherargs" to enable it.

Add a vhost_ops entry to compare the fds for vhost-user only. Cc: qemu-stable@nongnu.org Cc: Victor Kaplansky <victork@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2016-02-23bios-linker-loader: document+validate inputMichael S. Tsirkin
While guest/host ABI is documented in hw/acpi/bios-linker-loader.c, the API was left undocumented. This adds documentation for all API functions. Additionally, input is validated to make sure all pointers fall within range of provided files. To allow this validation for checksum commands, bios_linker_loader_add_checksum is changed to accept GArray * in place of void *.

2016-02-22log: Redirect stderr to logfile if deamonizedDimitris Aragiorgis
In case of daemonize, use the logfile passed with the -D option in order to redirect stderr to it instead of /dev/null. Also remove some unused code in log.h.

2016-02-22dump-guest-memory: add "detach" supportPeter Xu
If "detach" is provided, one thread is created to do the dump work, while main thread will return immediately. For each GuestPhysBlock, adding one more field "mr" to points to MemoryRegion that it belongs, also ref the mr before use.

2016-02-22throttle: Add support for burst periodsAlberto Garcia
This patch adds support for burst periods to the throttling code. With this feature the user can keep performing bursts as defined by the LeakyBucket.max rate for a configurable period of time.

2016-02-22throttle: Use throttle_config_init() to initialize ThrottleConfigAlberto Garcia
We can currently initialize ThrottleConfig by zeroing all its fields, but this will change with the new fields to define the length of the burst periods. This patch introduces a new throttle_config_init() function and uses it to replace all memset() calls that initialize ThrottleConfig directly.

2016-02-22throttle: Merge all functions that check the configuration into oneAlberto Garcia
There's no need to keep throttle_conflicting(), throttle_is_valid() and throttle_max_is_missing_limit() as separate functions, so this patch merges all three into one. As a consequence, check_throttle_config() becomes redundant and can be replaced with throttle_is_valid().
