2023-09-04ui/vc: do not parse VC-specific options in Spice and GTKMarc-André Lureau1-0/+4
In commit 6f974c843c ("gtk: overwrite the console.c char driver"), I shared the VC console parse handler with GTK. And later on in commit d8aec9d9 ("display: add -display spice-app launching a Spice client"), I also used it to handle spice-app VC. This is not necessary, the VC console options (width/height/cols/rows) are specific, and unused by tty-level GTK/Spice VC. This is not a breaking change, as those options are still being parsed by QAPI ChardevVC. Adjust the documentation about it.

Has return zero for more than 10 years. Specifically we introduced the field in 1.5.0 commit f1c72795af573b24a7da5eb52375c9aba8a37972 Author: Peter Lieven <pl@kamp.de> Date: Tue Mar 26 10:58:37 2013 +0100 migration: do not sent zero pages in bulk stage during bulk stage of ram migration if a page is a zero page do not send it at all. the memory at the destination reads as zero anyway. even if there is an madvise with QEMU_MADV_DONTNEED at the target upon receipt of a zero page I have observed that the target starts swapping if the memory is overcommitted. it seems that the pages are dropped asynchronously. this patch also updates QMP to return the number of skipped pages in MigrationStats. but removed its usage in 1.5.3 commit 9ef051e5536b6368a1076046ec6c4ec4ac12b5c6 Author: Peter Lieven <pl@kamp.de> Date: Mon Jun 10 12:14:19 2013 +0200 Revert "migration: do not sent zero pages in bulk stage" Not sending zero pages breaks migration if a page is zero at the source but not at the destination. This can e.g. happen if different BIOS versions are used at source and destination. It has also been reported that migration on pseries is completely broken with this patch.

Introduce migration dirty-limit capability, which can be turned on before live migration and limit dirty page rate durty live migration. Introduce migrate_dirty_limit function to help check if dirty-limit capability enabled during live migration. Meanwhile, refactor vcpu_dirty_rate_stat_collect so that period can be configured instead of hardcoded. dirty-limit capability is kind of like auto-converge but using dirty limit instead of traditional cpu-throttle to throttle guest down. To enable this feature, turn on the dirty-limit capability before live migration using migrate-set-capabilities, and set the parameters "x-vcpu-dirty-limit-period", "vcpu-dirty-limit" suitably to speed up convergence.

2023-06-30migration: Add switchover ack capabilityAvihai Horon1-1/+11
Migration downtime estimation is calculated based on bandwidth and remaining migration data. This assumes that loading of migration data in the destination takes a negligible amount of time and that downtime depends only on network speed. While this may be true for RAM, it's not necessarily true for other migrated devices. For example, loading the data of a VFIO device in the destination might require from the device to allocate resources, prepare internal data structures and so on. These operations can take a significant amount of time which can increase migration downtime. This patch adds a new capability "switchover ack" that prevents the source from stopping the VM and completing the migration until an ACK is received from the destination that it's OK to do so. This can be used by migrated devices in various ways to reduce downtime. For example, a device can send initial precopy metadata to pre-allocate resources in the destination and use this capability to make sure that the pre-allocation is completed before the source VM is stopped, so it will have full effect. This new capability relies on the return path capability to communicate from the destination back to the source. The actual implementation of the capability will be added in the following patches.

These events include a copy of the device health information at the time of the event. Actually using the emulated device health would require a lot of controls to manipulate that state. Given the aim of this injection code is to just test the flows when events occur, inject the contents of the device health state as well. Future work may add more sophisticate device health emulation including direct generation of these records when events occur (such as a temperature threshold being crossed). That does not reduce the usefulness of this more basic generation of the events.

2023-06-13exec/memory: Introduce RAM_NAMED_FILE flagSteve Sistare1-2/+2
migrate_ignore_shared() is an optimization that avoids copying memory that is visible and can be mapped on the target. However, a memory-backend-ram or a memory-backend-memfd block with the RAM_SHARED flag set is not migrated when migrate_ignore_shared() is true.

2023-06-05qcow2: add discard-no-unref optionJean-Louis Dupond1-0/+12
When we for example have a sparse qcow2 image and discard: unmap is enabled, there can be a lot of fragmentation in the image after some time. Especially on VM's that do a lot of writes/deletes. This causes the qcow2 image to grow even over 110% of its virtual size, because the free gaps in the image get too small to allocate new continuous clusters. So it allocates new space at the end of the image. Disabling discard is not an option, as discard is needed to keep the incremental backup size as low as possible. Without discard, the incremental backups would become large, as qemu thinks it's just dirty blocks but it doesn't know the blocks are unneeded. So we need to avoid fragmentation but also 'empty' the unneeded blocks in the image to have a small incremental backup. In addition, we also want to send the discards further down the stack, so the underlying blocks are still discarded. Therefor we introduce a new qcow2 option "discard-no-unref". When setting this option to true, discards will no longer have the qcow2 driver relinquish cluster allocations. Other than that, the request is handled as normal: All clusters in range are marked as zero, and, if pass-discard-request is true, it is passed further down the stack. The only difference is that the now-zero clusters are preallocated instead of being unallocated. This will avoid fragmentation on the qcow2 image.

2023-06-02cutils: Adjust signature of parse_uint[_full]Eric Blake1-6/+6
It's already confusing that we have two very similar functions for wrapping the parse of a 64-bit unsigned value, differing mainly on whether they permit leading '-'. Adjust the signature of parse_uint() and parse_uint_full() to be like all of qemu_strto*(): put the result parameter last, use the same types (uint64_t and unsigned long long have the same width, but are not always the same type), and mark endptr const (this latter change only affects the rare caller of parse_uint). Adjust all callers in the tree. While at it, note that since cutils.c already includes: QEMU_BUILD_BUG_ON(sizeof(int64_t) != sizeof(long long)); we are guaranteed that the result of parse_uint* cannot exceed UINT64_MAX (or the build would have failed), so we can drop pre-existing dead comparisons in opts-visitor.c that were never false.

The virtio-blk-vhost-vdpa driver in libblkio 1.3.0 supports the fd passing through the new 'fd' property. Since now we are using qemu_open() on '@path' if the virtio-blk driver supports the fd passing, let's announce it. In this way, the management layer can pass the file descriptor of an already opened vhost-vdpa character device. This is useful especially when the device can only be accessed with certain privileges. Add the '@fdset' feature only when the virtio-blk-vhost-vdpa driver in libblkio supports it.

This commit adds a new audiodev backend to allow QEMU to use Pipewire as both an audio sink and source. This backend is available on most systems Add Pipewire entry points for QEMU Pipewire audio backend Add wrappers for QEMU Pipewire audio backend in qpw_pcm_ops() qpw_write function returns the current state of the stream to pwaudio and Writes some data to the server for playback streams using pipewire spa_ringbuffer implementation. qpw_read function returns the current state of the stream to pwaudio and reads some data from the server for capture streams using pipewire spa_ringbuffer implementation. These functions qpw_write and qpw_read are called during playback and capture. Added some functions that convert pw audio formats to QEMU audio format and vice versa which would be needed in the pipewire audio sink and source functions qpw_init_in() & qpw_init_out(). These methods that implement playback and recording will create streams for playback and capture that will start processing and will result in the on_process callbacks to be called. Built a connection to the Pipewire sound system server in the qpw_audio_init() method.

2023-05-02qmp: Deprecate 'singlestep' member of StatusInfoPeter Maydell1-3/+11
The 'singlestep' member of StatusInfo has never done what the QMP documentation claims it does. What it actually reports is whether TCG is working in "one guest instruction per translation block" mode. We no longer need this field for the HMP 'info status' command, as we've moved that information to 'info jit'. It seems unlikely that anybody is monitoring the state of this obscure TCG setting via QMP, especially since QMP provides no means for changing the setting. So simply deprecate the field, without providing any replacement. Until we do eventually delete the member, correct the misstatements in the QAPI documentation about it. If we do find that there are users for this, then the most likely way we would provide replacement access to the information would be to put the accelerator QOM object at a well-known path such as /machine/accel, which could then be used with the existing qom-set and qom-get commands.
