2021-11-02watchdog: remove select_watchdog_actionPaolo Bonzini1-1/+0
Instead of invoking select_watchdog_action from both HMP and command line, go directly from HMP to QMP and use QemuOpts as the intermediary for the command line. This makes -watchdog-action explicitly a shortcut for "-action watchdog", so that "-watchdog-action" and "-action watchdog" override each other based on the position on the command line; previously, "-action watchdog" always won.

Make bytes argument int64_t to be consistent with modern block-layer. Callers should be OK with it as type becomes wider. What is inside functions? - Conversion from int64_t to size_t. Still, we can't have a buffer larger than SIZE_MAX, therefore bytes should not be larger than SIZE_MAX as well.

2021-10-15block-backend: convert blk_aio_ functions to int64_t bytes paramterVladimir Sementsov-Ogievskiy1-2/+2
1. Convert bytes in BlkAioEmAIOCB: aio->bytes is only passed to already int64_t interfaces, and set in blk_aio_prwv, which is updated here. 2. For all updated functions the parameter type becomes wider so callers are safe. 3. In blk_aio_prwv we only store bytes to BlkAioEmAIOCB, which is updated here. 4. Other updated functions are wrappers on blk_aio_prwv. Note that blk_aio_preadv and blk_aio_pwritev become safer: before this commit, it's theoretically possible to pass qiov with size exceeding INT_MAX, which than converted to int argument of blk_aio_prwv. Now it's converted to int64_t which is a lot better. Still add assertions.

Note also that we don't (and are not going to) convert blk_pwrite and blk_pread: these functions return number of bytes on success, so to update them, we should change return type to int64_t as well, which will lead to investigating and updating all callers which is too much.

2021-10-06block: introduce max_hw_iov for use in scsi-genericPaolo Bonzini1-0/+1
Linux limits the size of iovecs to 1024 (UIO_MAXIOV in the kernel sources, IOV_MAX in POSIX). Because of this, on some host adapters requests with many iovecs are rejected with -EINVAL by the io_submit() or readv()/writev() system calls. In fact, the same limit applies to SG_IO as well. To fix both the EINVAL and the possible performance issues from using fewer iovecs than allowed by Linux (some HBAs have max_segments as low as 128), introduce a separate entry in BlockLimits to hold the max_segments value from sysfs. This new limit is used only for SG_IO and clamped to bs->bl.max_iov anyway, just like max_hw_transfer is clamped to bs->bl.max_transfer.

Sleep on WFI until the VTIMER is due but allow ourselves to be woken up on IPI. In this implementation IPI is blocked on the CPU thread at startup and pselect() is used to atomically unblock the signal and begin sleeping. The signal is sent unconditionally so there's no need to worry about races between actually sleeping and the "we think we're sleeping" state. It may lead to an extra wakeup but that's better than missing it entirely.

2021-07-21iothread: add aio-max-batch parameterStefano Garzarella1-0/+3
The `aio-max-batch` parameter will be propagated to AIO engines and it will be used to control the maximum number of queued requests. When there are in queue a number of requests equal to `aio-max-batch`, the engine invokes the system call to forward the requests to the kernel. This parameter allows us to control the maximum batch size to reduce the latency that requests might accumulate while queued in the AIO engine queue. If `aio-max-batch` is equal to 0 (default value), the AIO engine will use its default maximum batch size value.

2021-06-25block: add max_hw_transfer to BlockLimitsPaolo Bonzini1-0/+1
For block host devices, I/O can happen through either the kernel file descriptor I/O system calls (preadv/pwritev, io_submit, io_uring) or the SCSI passthrough ioctl SG_IO. In the latter case, the size of each transfer can be limited by the HBA, while for file descriptor I/O the kernel is able to split and merge I/O in smaller pieces as needed. Applying the HBA limits to file descriptor I/O results in more system calls and suboptimal performance, so this patch splits the max_transfer limit in two: max_transfer remains valid and is used in general, while max_hw_transfer is limited to the maximum hardware size. max_hw_transfer can then be included by the scsi-generic driver in the block limits page, to ensure that the stricter hardware limit is used.

2021-06-15hostmem: Wire up RAM_NORESERVE via "reserve" propertyDavid Hildenbrand1-1/+1
Let's provide a way to control the use of RAM_NORESERVE via memory backends using the "reserve" property which defaults to true (old behavior). Only Linux currently supports clearing the flag (and support is checked at runtime, depending on the setting of "/proc/sys/vm/overcommit_memory"). Windows and other POSIX systems will bail out with "reserve=false". The target use case is virtio-mem, which dynamically exposes memory inside a large, sparse memory area to the VM. This essentially allows avoiding to set "/proc/sys/vm/overcommit_memory == 0") when using virtio-mem and also supporting hugetlbfs in the future. As really only Linux implements RAM_NORESERVE right now, let's expose the property only with CONFIG_LINUX. Setting the property to "false" will then only fail in corner cases -- for example on very old kernels or when memory overcommit was completely disabled by the admin.

2021-06-03hvf: Split out common code on vcpu init and destroyAlexander Graf1-0/+2
Until now, Hypervisor.framework has only been available on x86_64 systems. With Apple Silicon shipping now, it extends its reach to aarch64. To prepare for support for multiple architectures, let's start moving common code out into its own accel directory. This patch splits the vcpu init and destroy functions into a generic and an architecture specific portion. This also allows us to move the generic functions into the generic hvf code, removing exported functions.

2021-05-26KVM: Provide helper to sync dirty bitmap from slot to ramblockPeter Xu1-0/+2
kvm_physical_sync_dirty_bitmap() calculates the ramblock offset in an awkward way from the MemoryRegionSection that passed in from the caller. The truth is for each KVMSlot the ramblock offset never change for the lifecycle. Cache the ramblock offset for each KVMSlot into the structure when the KVMSlot is created. With that, we can further simplify kvm_physical_sync_dirty_bitmap() with a helper to sync KVMSlot dirty bitmap to the ramblock dirty bitmap of a specific KVMSlot.

2021-05-26KVM: Use a big lock to replace per-kml slots_lockPeter Xu1-2/+0
Per-kml slots_lock will bring some trouble if we want to take all slots_lock of all the KMLs, especially when we're in a context that we could have taken some of the KML slots_lock, then we even need to figure out what we've taken and what we need to take. Make this simple by merging all KML slots_lock into a single slots lock. Per-kml slots_lock isn't anything that helpful anyway - so far only x86 has two address spaces (so, two slots_locks). All the rest archs will be having one address space always, which means there's actually one slots_lock so it will be the same as before.

Both os-win32.h and os-posix.h include system header files. Instead of having osdep.h include them inside its 'extern "C"' block, make these headers handle that themselves, so that we don't include the system headers inside 'extern "C"'. This doesn't fix any current problems, but it's conceptually the right way to handle system headers.

Similarly to 5f629d943cb0 ("s390x: fix s390 virtio aliases"), define the virtio aliases. This allows to start machines with virtio devices without knowledge of the implementation type. For instance, we can use "-device virtio-scsi" on m68k, s390x or PC, and the device will be respectively "virtio-scsi-device", "virtio-scsi-ccw" or "virtio-scsi-pci". This already exists for s390x and -ccw interfaces, add them for m68k and MMIO (-device) interfaces.
