2023-03-07stubs: split semihosting_get_target from system only stubsAlex Bennée

2023-02-27replay: Extract core API to 'exec/replay-core.h'Philippe Mathieu-Daudé
replay API is used deeply within TCG common code (common to user and system emulation). Unfortunately "sysemu/replay.h" requires some QAPI headers for few system-specific declarations, example: void replay_input_event(QemuConsole *src, InputEvent *evt); Since commit c2651c0eaa ("qapi/meson: Restrict UI module to system emulation and tools") the QAPI header defining the InputEvent is not generated anymore. To keep it simple, extract the 'core' replay prototypes to a new "exec/replay-core.h" header which we include in the TCG code that doesn't need the rest of the replay API.

2023-02-23hw/acpi: Move QMP command to hw/core/Markus Armbruster
The QERR_ macros are leftovers from the days of "rich" error objects. We've been trying to reduce their remaining use. qmp_query_vm_generation_id() in stubs/vmgenid.c is the last user of QERR_UNSUPPORTED outside qga/. Unlike the stubs we just dropped, it is actually reachable, namely when CONFIG_ACPI_VMGENID is off. It always fails like (qemu) info vm-generation-id Error: this feature or command is not currently supported Turns out the real qmp_query_vm_generation_id() doesn't actually depend on CONFIG_ACPI_VMGENID, and fails safely when it's off. Move it to hw/core/machine-qmp-cmds.c, and drop the stub. The error message becomes Error: VM Generation ID device not found Feels like an improvement to me.

The has_FOO for pointer-valued FOO are redundant, except for arrays. They are also a nuisance to work with.

2022-10-26stubs: add qemu_ram_block_from_host() and qemu_ram_get_fd()Stefan Hajnoczi
The blkio block driver will need to look up the file descriptor for a given pointer. This is possible in softmmu builds where the RAMBlock API is available for querying guest RAM. Add stubs so tools like qemu-img that link the block layer still build successfully. In this case there is no guest RAM but that is fine. Bounce buffers and their file descriptors will be allocated with libblkio's blkio_alloc_mem_region() so we won't rely on QEMU's qemu_ram_get_fd() in that case.

2022-09-13semihosting: Allow optional use of semihosting from userspacePeter Maydell
Currently our semihosting implementations generally prohibit use of semihosting calls in system emulation from the guest userspace. This is a very long standing behaviour justified originally "to provide some semblance of security" (since code with access to the semihosting ABI can do things like read and write arbitrary files on the host system). However, it is sometimes useful to be able to run trusted guest code which performs semihosting calls from guest userspace, notably for test code. Add a command line suboption to the existing semihosting-config option group so that you can explicitly opt in to semihosting from guest userspace with -semihosting-config userspace=on (There is no equivalent option for the user-mode emulator, because there by definition all code runs in userspace and has access to semihosting already.) This commit adds the infrastructure for the command line option and adds a bool 'is_user' parameter to the function semihosting_userspace_enabled() that target code can use to check whether it should be permitting the semihosting call for userspace. It mechanically makes all the callsites pass 'false', so they continue checking "is semihosting enabled in general". Subsequent commits will make each target that implements semihosting honour the userspace=on option by passing the correct value and removing whatever "don't do this for userspace" checking they were doing by hand.

When invoked from the main loop, this function is the same as qemu_mutex_iothread_locked, and returns true if the BQL is held. When invoked from iothreads or tests, it returns true only if the current AioContext is the Main Loop. This essentially just extends qemu_mutex_iothread_locked to work also in unit tests or other users like storage-daemon, that run in the Main Loop but end up using the implementation in stubs/iothread-lock.c. Using qemu_mutex_iothread_locked in unit tests defaults to false because they use the implementation in stubs/iothread-lock, making all assertions added in next patches fail despite the AioContext is still the main loop.

2021-06-18async: the main AioContext is only "current" if under the BQLPaolo Bonzini
If we want to wake up a coroutine from a worker thread, aio_co_wake() currently does not work. In that scenario, aio_co_wake() calls aio_co_enter(), but there is no current AioContext and therefore qemu_get_current_aio_context() returns the main thread. aio_co_wake() then attempts to call aio_context_acquire() instead of going through aio_co_schedule(). The default case of qemu_get_current_aio_context() was added to cover synchronous I/O started from the vCPU thread, but the main and vCPU threads are quite different. The main thread is an I/O thread itself, only running a more complicated event loop; the vCPU thread instead is essentially a worker thread that occasionally calls qemu_mutex_lock_iothread(). It is only in those critical sections that it acts as if it were the home thread of the main AioContext. Therefore, this patch detaches qemu_get_current_aio_context() from iothreads, which is a useless complication. The AioContext pointer is stored directly in the thread-local variable, including for the main loop. Worker threads (including vCPU threads) optionally behave as temporary home threads if they have taken the big QEMU lock, but if that is not the case they will always schedule coroutines on remote threads via aio_co_schedule(). With this change, the stub qemu_mutex_iothread_locked() must be changed from true to false. The previous value of true was needed because the main thread did not have an AioContext in the thread-local variable, but now it does have one.

2021-05-26qemu-config: load modules when instantiating option groupsPaolo Bonzini
Right now the SPICE module is special cased to be loaded when processing of the -spice command line option. However, the spice option group can also be brought in via -readconfig, in which case the module is not loaded. Add a generic hook to load modules that provide a QemuOpts group, and use it for the "spice" and "iscsi" groups.

2021-02-16replay: fix icount request when replaying clock accessPavel Dovgalyuk
Record/replay provides REPLAY_CLOCK_LOCKED macro to access the clock when vm_clock_seqlock is locked. This macro is needed because replay internals operate icount. In locked case replay use icount_get_raw_locked for icount request, which prevents excess locking which leads to deadlock. But previously only record code used *_locked function and replay did not. Therefore sometimes clock access lead to deadlocks. This patch fixes clock access for replay too and uses *_locked icount access function.
