* hostmem: Allow for specifying a ThreadContext for preallocationDavid Hildenbrand2022-10-271-0/+4
| | | | | | | | | | | | | | | | | | Let's allow for specifying a thread context via the "prealloc-context" property. When set, preallcoation threads will be crated via the thread context -- inheriting the same CPU affinity as the thread context. Pinning preallcoation threads to CPUs can heavily increase performance in NUMA setups, because, preallocation from a CPU close to the target NUMA node(s) is faster then preallocation from a CPU further remote, simply because of memory bandwidth for initializing memory with zeroes. This is especially relevant for very large VMs backed by huge/gigantic pages, whereby preallocation is mandatory.

* util: Add write-only "node-affinity" property for ThreadContextDavid Hildenbrand2022-10-271-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's make it easier to pin threads created via a ThreadContext to all host CPUs currently belonging to a given set of host NUMA nodes -- which is the common case. "node-affinity" is simply a shortcut for setting "cpu-affinity" manually to the list of host CPUs belonging to the set of host nodes. This property can only be written. A simple QEMU example to set the CPU affinity to host node 1 on a system with two nodes, 24 CPUs each, whereby odd-numbered host CPUs belong to host node 1: qemu-system-x86_64 -S \ -object thread-context,id=tc1,node-affinity=1 And we can query the cpu-affinity via HMP/QMP: (qemu) qom-get tc1 cpu-affinity [ 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47 ] We cannot query the node-affinity: (qemu) qom-get tc1 node-affinity Error: Insufficient permission to perform this operation But note that due to dynamic library loading this example will not work before we actually make use of thread_context_create_thread() in QEMU code, because the type will otherwise not get registered. We'll wire this up next to make it work. Note that if the host CPUs for a host node change due do CPU hot(un)plug CPU onlining/offlining (i.e., lscpu output changes) after the ThreadContext was started, the CPU affinity will not get updated.

* util: Introduce ThreadContext user-creatable objectDavid Hildenbrand2022-10-271-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setting the CPU affinity of QEMU threads is a bit problematic, because QEMU doesn't always have permissions to set the CPU affinity itself, for example, with seccomp after initialized by QEMU: -sandbox enable=on,resourcecontrol=deny General information about CPU affinities can be found in the man page of taskset: CPU affinity is a scheduler property that "bonds" a process to a given set of CPUs on the system. The Linux scheduler will honor the given CPU affinity and the process will not run on any other CPUs. While upper layers are already aware of how to handle CPU affinities for long-lived threads like iothreads or vcpu threads, especially short-lived threads, as used for memory-backend preallocation, are more involved to handle. These threads are created on demand and upper layers are not even able to identify and configure them. Introduce the concept of a ThreadContext, that is essentially a thread used for creating new threads. All threads created via that context thread inherit the configured CPU affinity. Consequently, it's sufficient to create a ThreadContext and configure it once, and have all threads created via that ThreadContext inherit the same CPU affinity. The CPU affinity of a ThreadContext can be configured two ways: (1) Obtaining the thread id via the "thread-id" property and setting the CPU affinity manually (e.g., via taskset). (2) Setting the "cpu-affinity" property and letting QEMU try set the CPU affinity itself. This will fail if QEMU doesn't have permissions to do so anymore after seccomp was initialized. A simple QEMU example to set the CPU affinity to host CPU 0,1,6,7 would be: qemu-system-x86_64 -S \ -object thread-context,id=tc1,cpu-affinity=0-1,cpu-affinity=6-7 And we can query it via HMP/QMP: (qemu) qom-get tc1 cpu-affinity [ 0, 1, 6, 7 ] But note that due to dynamic library loading this example will not work before we actually make use of thread_context_create_thread() in QEMU code, because the type will otherwise not get registered. We'll wire this up next to make it work. In general, the interface behaves like pthread_setaffinity_np(): host CPU numbers that are currently not available are ignored; only host CPU numbers that are impossible with the current kernel will fail. If the list of host CPU numbers does not include a single CPU that is available, setting the CPU affinity will fail. A ThreadContext can be reused, simply by reconfiguring the CPU affinity. Note that the CPU affinity of previously created threads will not get adjusted.

* util/event-loop-base: Introduce options to set the thread pool sizeNicolas Saenz Julienne2022-05-091-1/+9
| | | | | | | | | | | | | | | | | | | | | | The thread pool regulates itself: when idle, it kills threads until empty, when in demand, it creates new threads until full. This behaviour doesn't play well with latency sensitive workloads where the price of creating a new thread is too high. For example, when paired with qemu's '-mlock', or using safety features like SafeStack, creating a new thread has been measured take multiple milliseconds. In order to mitigate this let's introduce a new 'EventLoopBase' property to set the thread pool size. The threads will be created during the pool's initialization or upon updating the property's value, remain available during its lifetime regardless of demand, and destroyed upon freeing it. A properly characterized workload will then be able to configure the pool to avoid any latency spikes.

* Introduce event-loop-base abstract classNicolas Saenz Julienne2022-05-091-5/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce the 'event-loop-base' abstract class, it'll hold the properties common to all event loops and provide the necessary hooks for their creation and maintenance. Then have iothread inherit from it. EventLoopBaseClass is defined as user creatable and provides a hook for its children to attach themselves to the user creatable class 'complete' function. It also provides an update_params() callback to propagate property changes onto its children. The new 'event-loop-base' class will live in the root directory. It is built on its own using the 'link_whole' option (there are no direct function dependencies between the class and its children, it all happens trough 'constructor' magic). And also imposes new compilation dependencies: qom <- event-loop-base <- blockdev (iothread.c) And in subsequent patches: qom <- event-loop-base <- qemuutil (util/main-loop.c) All this forced some amount of reordering in meson.build: - Moved qom build definition before qemuutil. Doing it the other way around (i.e. moving qemuutil after qom) isn't possible as a lot of core libraries that live in between the two depend on it. - Process the 'hw' subdir earlier, as it introduces files into the 'qom' source set. No functional changes intended.

* hostmem: Wire up RAM_NORESERVE via "reserve" propertyDavid Hildenbrand2021-06-151-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

In addition, this causes ObjectType to have different definitions depending on the file that is including qapi-types-qom.h (currently this is not causing any issues, but it is wrong). Define the two enum entries and the SevGuestProperties type unconditionally to avoid the issue.

Once all other places (HMP and command lines of the system emulator and all tools) go through QAPI, too, some object implementations can be simplified because some checks (e.g. that mandatory options are set) are already performed by QAPI, and in another step, QOM boilerplate code could be generated from the schema.

Some parts of the interface (in particular NetfilterProperties.position) are very unusual for QAPI, but for now just describe the existing interface. net.json can't be included in qom.json because the storage daemon doesn't have it. NetFilterDirection is still required in the new object property definitions in qom.json, so move this enum to common.json.

| | | | | | | | | | | | | | | | | | This adds a QAPI schema for the properties of the throttle-group object. The only purpose of the x-* properties is to make the nested options in 'limits' available for a command line parser that doesn't support structs. Any parser that will use the QAPI schema will supports structs, though, so they will not be needed in the schema in the future. To keep the conversion straightforward, add them to the schema anyway. We can then remove the options and adjust documentation, test cases etc. in a separate patch.

After the property has once been set to true (i.e. when the object construction has completed), it can never be reset to false. In other words, the 'opened' property is useless.

* schemas: Add vim modelineAndrea Bolognani2020-08-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | The various schemas included in QEMU use a JSON-based format which is, however, strictly speaking not valid JSON. As a consequence, when vim tries to apply syntax highlight rules for JSON (as guessed from the file name), the result is an unreadable mess which mostly consist of red markers pointing out supposed errors in, well, pretty much everything. Using Python syntax highlighting produces much better results, and in fact these files already start with specially-formatted comments that instruct Emacs to process them as if they were Python files. This commit adds the equivalent special comments for vim. Signed-off-by: Andrea Bolognani <abologna@redhat.com> Message-Id: <20200729185024.121766-1-abologna@redhat.com> Reviewed-by: Daniel P.

| | | | | | | | | | | | | | Mapping object-add to the command line as is doesn't result in nice syntax because of the nesting introduced with 'props'.

* qapi: Fix indent level on doc comments in json filesPeter Maydell2020-02-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current doc generation doesn't care much about indentation levels, but we would like to switch to an rST format, and rST does care about indentation. Make the doc comments more strongly consistent about indentation for multiline constructs like: @arg: description line 1 description line 2 Returns: line one line 2 so that there is always exactly one space after the colon, and subsequent lines align with the first. This commit is a purely whitespace change, and it does not alter the generated .texi files (because the texi generation code strips away all the extra whitespace). This does mean that we end up with some over-length lines. Note that when the documentation for an argument fits on a single line like this: @arg: one line only then stray extra spaces after the ':' don't affect the rST output, so I have not attempted to methodically fix them, though the preference is a single space here too.
