2023-02-04include/qemu/int128: Use Int128 structure for TCIRichard Henderson
We are about to allow passing Int128 to/from tcg helper functions, but libffi doesn't support __int128_t, so use the structure. In order for atomic128.h to continue working, we must provide a mechanism to frob between real __int128_t and the structure. Provide a new union, Int128Alias, for this. We cannot modify Int128 itself, as any changed alignment would also break libffi.

2023-01-23util/aio: Defer disabling poll mode as long as possibleChao Gao
When we measure FIO read performance (cache=writethrough, bs=4k, iodepth=64) in VMs, ~80K/s notifications (e.g., EPT_MISCONFIG) are observed from guest to qemu. It turns out those frequent notificatons are caused by interference from worker threads. Worker threads queue bottom halves after completing IO requests. Pending bottom halves may lead to either aio_compute_timeout() zeros timeout and pass it to try_poll_mode() or run_poll_handlers() returns no progress after noticing pending aio_notify() events. Both cause run_poll_handlers() to call poll_set_started(false) to disable poll mode. However, for both cases, as timeout is already zeroed, the event loop (i.e., aio_poll()) just processes bottom halves and then starts the next event loop iteration. So, disabling poll mode has no value but leads to unnecessary notifications from guest. To minimize unnecessary notifications from guest, defer disabling poll mode to when the event loop is about to be blocked. With this patch applied, FIO seq-read performance (bs=4k, iodepth=64, cache=writethrough) in VMs increases from 330K/s to 413K/s IOPS.

2023-01-11accel: introduce accelerator blocker APIEmanuele Giuseppe Esposito
This API allows the accelerators to prevent vcpus from issuing new ioctls while execting a critical section marked with the accel_ioctl_inhibit_begin/end functions. Note that all functions submitting ioctls must mark where the ioctl is being called with accel_{cpu_}ioctl_begin/end(). This API requires the caller to always hold the BQL. API documentation is in sysemu/accel-blocker.h Internally, it uses a QemuLockCnt together with a per-CPU QemuLockCnt (to minimize cache line bouncing) to keep avoid that new ioctls run when the critical section starts, and a QemuEvent to wait that all running ioctls finish.

2023-01-06util/log: Always send errors to logfile when daemonizedGreg Kurz
When QEMU is started with `-daemonize`, all stdio descriptors get redirected to `/dev/null`. This basically means that anything printed with error_report() and friends is lost. Current logging code allows to redirect to a file with `-D` but this requires to enable some logging item with `-d` as well to be functional. Relax the check on the log flags when QEMU is daemonized, so that other users of stderr can benefit from the redirection, without the need to enable unwanted debug logs. Previous behaviour is retained for the non-daemonized case. The logic is unrolled as an `if` for better readability. The qemu_log_level and log_per_thread globals reflect the state we want to transition to at this point : use them instead of the intermediary locals for correctness. qemu_set_log_internal() is adapted to open a per-thread log file when '-d tid' is passed. This is done by hijacking qemu_try_lock() which seems simpler that refactoring the code.

2023-01-06util/log: do not close and reopen log files when flags are turned offPaolo Bonzini
log_append makes sure that if you turn off the logging (which clears log_flags and makes need_to_open_file false) the old log is not overwritten. The usecase is that if you remove or move the file QEMU will not keep writing to the old file. However, this is not always the desited behavior, in particular having log_append==1 after changing the file name makes little sense. When qemu_set_log_internal is called from the logfile monitor command, filename must be non-NULL and therefore changed_name must be true. Therefore, the only case where the file is closed and need_to_open_file == false is indeed when log_flags becomes zero. In this case, just flush the file and do not bother closing it, thus faking the same append behavior as previously. The behavioral change is that changing the logfile twice, for example log1 -> log2 -> log1, will cause log1 to be overwritten. This can simply be documented, since it is not a particularly surprising behavior.

2022-12-15util/qemu-config: Fix "query-command-line-options" to provide the right valuesThomas Huth
The "query-command-line-options" command uses a hand-crafted list of options that should be returned for the "machine" parameter. This is pretty much out of sync with reality, for example settings like "kvm_shadow_mem" or "accel" are not parameters for the machine anymore. Also, there is no distinction between the targets here, so e.g. the s390x-specific values like "loadparm" in this list also show up with the other targets like x86_64. Let's fix this now by geting rid of the hand-crafted list and by querying the properties of the machine classes instead to assemble the list.

2022-12-14qapi misc: Elide redundant has_FOO in generated CMarkus Armbruster
The has_FOO for pointer-valued FOO are redundant, except for arrays. They are also a nuisance to work with. Recent commit "qapi: Start to elide redundant has_FOO in generated C" provided the means to elide them step by step. This is the step for qapi/misc.json. Said commit explains the transformation in more detail. The invariant violations mentioned there do not occur here.

Since we already have bitmap_mutex to protect either the dirty bitmap or the clear log bitmap, we don't need atomic operations to set/clear/test on the clear log bitmap. Switching all ops from atomic to non-atomic versions, meanwhile touch up the comments to show which lock is in charge.

2022-11-07util/log: Ignore per-thread flag if global file already thereGreg Kurz
If QEMU is started with `-D qemu.log.%d` without any `-d` option, doing `log all` in the monitor fails with: Filename template with '%d' required for 'tid' It is confusing since '%d' was actually passed. This happens because QEMU caches the log file name with %d converted to getpid() since `tid` wasn't required. This name isn't suitable for a subsequent enablement of per-thread logs. There's little cause to change the behavior as `-d tid` is mostly used at user-only startup. Drop the per-thread from the requested flags in this case : `log all` will thus enable everything except `tid` instead of failing. This is preferable over forcing the user to enable each log item individually. With this patch, `tid` is now truely immutable : it can only be set or unset from the command line and never changed afterwards.

2022-11-07util/log: Make the per-thread flag immutableGreg Kurz
Per-thread logging was implemented under the assumption that once enabled, it is not possible to switch back to single file logging. This isn't enforced though and it is possible to go through the global file opening sequence in per-thread mode. The code isn't ready for this and produces unexpected results as detailed below. Start QEMU in system emulation mode with `-D ./qemu.log.%d -d tid` and then change the log level from the monitor to something that doesn't have tid, e.g. `log cpu_reset`. The value of log_flags is zero and per_thread is set to false : the rest of the code then assumes it is running in the global log case and opens a file named `qemu.log.%d`, which is obviously not an expected behavior. Enforce the immutability of the flag early in qemu_set_log_internal() so that its value is correct for all subsequent users.

2022-11-06module: add Error arguments to module_load and module_load_qomClaudio Fontana
improve error handling during module load, by changing: bool module_load(const char *prefix, const char *lib_name); void module_load_qom(const char *type); to: int module_load(const char *prefix, const char *name, Error **errp); int module_load_qom(const char *type, Error **errp); where the return value is: -1 on module load error, and errp is set with the error 0 on module or one of its dependencies are not installed 1 on module load success 2 on module load success (module already loaded or built-in) module_load_qom_one has been introduced in: commit 28457744c345 ("module: qom module support"), which built on top of module_load_one, but discarded the bool return value. Restore it. Adapt all callers to emit errors, or ignore them, or fail hard, as appropriate in each context. Replace the previous emission of errors via fprintf in _some_ error conditions with Error and error_report, so as to emit to the appropriate target. A memory leak is also fixed as part of the module_load changes. audio: when attempting to load an audio module, report module load errors. Note that still for some callers, a single issue may generate multiple error reports, and this could be improved further. Regarding the audio code itself, audio_add() seems to ignore errors, and this should probably be improved. block: when attempting to load a block module, report module load errors. For the code paths that already use the Error API, take advantage of those to report module load errors into the Error parameter. For the other code paths, we currently emit the error, but this could be improved further by adding Error parameters to all possible code paths. console: when attempting to load a display module, report module load errors. qdev: when creating a new qdev Device object (DeviceState), report load errors. If a module cannot be loaded to create that device, now abort execution (if no CONFIG_MODULE) or exit (if CONFIG_MODULE). qom/object.c: when initializing a QOM object, or looking up class_by_name, report module load errors. qtest: when processing the "module_load" qtest command, report errors in the load of the module.

2022-10-31util/log: Close per-thread log file on thread terminationGreg Kurz
When `-D ${logfile} -d tid` is passed, qemu_log_trylock() creates a dedicated log file for the current thread and opens it. The corresponding file descriptor is cached in a __thread variable. Nothing is done to close the corresponding file descriptor when the thread terminates though and the file descriptor is leaked. The issue was found during code inspection and reproduced manually. Fix that with an atexit notifier.

2022-10-31os-posix: asynchronous teardown for shutdown on LinuxClaudio Imbrenda
This patch adds support for asynchronously tearing down a VM on Linux. When qemu terminates, either naturally or because of a fatal signal, the VM is torn down. If the VM is huge, it can take a considerable amount of time for it to be cleaned up. In case of a protected VM, it might take even longer than a non-protected VM (this is the case on s390x, for example). Some users might want to shut down a VM and restart it immediately, without having to wait. This is especially true if management infrastructure like libvirt is used. This patch implements a simple trick on Linux to allow qemu to return immediately, with the teardown of the VM being performed asynchronously. If the new commandline option -async-teardown is used, a new process is spawned from qemu at startup, using the clone syscall, in such way that it will share its address space with qemu.The new process will have the name "cleanup/<QEMU_PID>". It will wait until qemu terminates completely, and then it will exit itself. This allows qemu to terminate quickly, without having to wait for the whole address space to be torn down. The cleanup process will exit after qemu, so it will be the last user of the address space, and therefore it will take care of the actual teardown. The cleanup process will share the same cgroups as qemu, so both memory usage and cpu time will be accounted properly. If possible, close_range will be used in the cleanup process to close all open file descriptors. If it is not available or if it fails, /proc will be used to determine which file descriptors to close. If the cleanup process is forcefully killed with SIGKILL before the main qemu process has terminated completely, the mechanism is defeated and the teardown will not be asynchronous.

2022-10-28tests/qtest: Use send/recv for socket communicationXuzhou Cheng
Socket communication in the libqtest and libqmp codes uses read() and write() which work on any file descriptor on *nix, and sockets in *nix are an example of a file descriptor. However sockets on Windows do not use *nix-style file descriptors, so read() and write() cannot be used on sockets on Windows. Switch over to use send() and recv() instead which work on both Windows and *nix.

2022-10-28qemu-sockets: update socket_uri() and socket_parse() to be consistentLaurent Vivier
To be consistent with socket_uri(), add 'tcp:' prefix for inet type in socket_parse(), by default socket_parse() use tcp when no prefix is provided (format is host:port). In socket_uri(), use 'vsock:' prefix for vsock type rather than 'tcp:' because it makes a vsock address look like an inet address with CID misinterpreted as host.
