* kvm: allow target-specific accelerator propertiesPaolo Bonzini2022-10-101-0/+2
| | | | | | | | | | | | | Several hypervisor capabilities in KVM are target-specific. When exposed to QEMU users as accelerator properties (i.e. -accel kvm,prop=value), they should not be available for all targets. Add a hook for targets to add their own properties to -accel kvm, for now no such property is defined.

* gdbstub: move breakpoint logic to accel opsAlex Bennée2022-10-063-5/+9
| | | | | | | | | | | | As HW virtualization requires specific support to handle breakpoints lets push out special casing out of the core gdbstub code and into AccelOpsClass. This will make it easier to add other accelerator support and reduces some of the stub shenanigans.

* gdbstub: move sstep flags probing into AccelClassAlex Bennée2022-10-061-8/+0Star
| | | | | | | | | | | | | The support of single-stepping is very much dependent on support from the accelerator we are using. To avoid special casing in gdbstub move the probing out to an AccelClass function so future accelerators can put their code there.

* | ui/cocoa: Run qemu_init in the main threadAkihiko Odaki2022-09-231-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | This work is based on: https://patchew.org/QEMU/20220317125534.38706-1-philippe.mathieu.daude@gmail.com/ Simplify the initialization dance by running qemu_init() in the main thread before the Cocoa event loop starts. The secondary thread only runs only qemu_main_loop() and qemu_cleanup(). This fixes a case where addRemovableDevicesMenuItems() calls qmp_query_block() while expecting the main thread to still hold the BQL. Overriding the code after calling qemu_init() is done by dynamically replacing a function pointer variable, qemu_main when initializing ui/cocoa, which unifies the static implementation of main() for builds with ui/cocoa and ones without ui/cocoa.

| | | | | | | | | | | | | | | | The "-display sdl" option still uses a hand-crafted parser for its parameters since we didn't want to drag an interface we considered somewhat flawed into the QAPI schema. Since the flaws are gone now, it's time to QAPIfy. This introduces the new "DisplaySDL" QAPI struct that is used to hold the parameters that are unique to the SDL display. The only specific parameter is currently "grab-mod" that is used to specify the required modifier keys to escape from the mouse grabbing mode.

| * util/event-loop-base: Introduce options to set the thread pool sizeNicolas Saenz Julienne2022-05-091-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 'event-loop-base' provides basic property handling for all 'AioContext' based event loops. So let's define a new 'MainLoopClass' that inherits from it. This will permit tweaking the main loop's properties through qapi as well as through the command line using the '-object' keyword[1]. Only one instance of 'MainLoopClass' might be created at any time. 'EventLoopBaseClass' learns a new callback, 'can_be_deleted()' so as to mark 'MainLoop' as non-deletable.

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.

* | Warn user if the vga flag is passed but no vga device is createdGautam Agrawal2022-05-091-0/+1
|/ | | | | | | | | | | | | | | | | | | | | | A global boolean variable "vga_interface_created"(declared in softmmu/globals.c) has been used to track the creation of vga interface. If the vga flag is passed in the command line "default_vga"(declared in softmmu/vl.c) variable is set to 0. To warn user, the condition checks if vga_interface_created is false and default_vga is equal to 0. If "-vga none" is passed, this patch will not warn the user regarding the creation of VGA device. The warning "A -vga option was passed but this machine type does not use that option; no VGA device has been created" is logged if vga flag is passed but no vga device is created. This patch has been tested for x86_64, i386, sparc, sparc64 and arm boards.
