2023-10-12softmmu: pass the main loop status to gdb "Wxx" packetClément Chigot
gdb_exit function aims to close gdb sessions and sends the exit code of the current execution. It's being called by qemu_cleanup once the main loop is over. Until now, the exit code sent was always 0. Now that hardware can shutdown this main loop with custom exit codes, these codes must be transfered to gdb as well.

2023-10-12softmmu: add means to pass an exit code when requesting a shutdownClément Chigot
As of now, the exit code was either EXIT_FAILURE when a panic shutdown was requested or EXIT_SUCCESS otherwise. However, some hardware could want to pass more complex exit codes. Thus, introduce a new shutdown request function allowing that.

hvf_get_supported_cpuid() is only defined for x86 targets (in target/i386/hvf/x86_cpuid.c). Its declaration is pointless on all other targets. All the calls to it in target/i386/cpu.c are guarded by a call on hvf_enabled(), so are elided when HVF is not built in. Therefore we can remove the unnecessary function stub.

2023-09-11sysemu: Add prepare callback to struct VMChangeStateEntryAvihai Horon
Add prepare callback to struct VMChangeStateEntry. The prepare callback is optional and can be set by the new function qemu_add_vm_change_state_handler_prio_full() that allows setting this callback in addition to the main callback. The prepare callbacks and main callbacks are called in two separate phases: First all prepare callbacks are called and only then all main callbacks are called. The purpose of the new prepare callback is to allow all devices to run a preliminary task before calling the devices' main callbacks. This will facilitate adding P2P support for VFIO migration where all VFIO devices need to be put in an intermediate P2P quiescent state before being stopped or started by the main callback.

This will stop linking softmmu-specific os_parse_cmd_args() into every qemu executable which happens to use other functions from os-posix.c, such as os_set_line_buffering() or os_setup_signal_handling(). Also, since there's no win32-specific options, *all* option parsing is now done in softmmu/vl.c:qemu_init(), which is easier to read without extra indirection, - all options are in the single function now.

2023-08-31accel: Remove HAX acceleratorPhilippe Mathieu-Daudé
HAX is deprecated since commits 73741fda6c ("MAINTAINERS: Abort HAXM maintenance") and 90c167a1da ("docs/about/deprecated: Mark HAXM in QEMU as deprecated"), released in v8.0.0. Per the latest HAXM release (v7.8 [*]), the latest QEMU supported is v7.2: Note: Up to this release, HAXM supports QEMU from 2.9.0 to 7.2.0. The next commit (https://github.com/intel/haxm/commit/da1b8ec072) added: HAXM v7.8.0 is our last release and we will not accept pull requests or respond to issues after this. It became very hard to build and test HAXM. Its previous maintainers made it clear they won't help. It doesn't seem to be a very good use of QEMU maintainers to spend their time in a dead project. Save our time by removing this orphan zombie code.

2023-08-31rtc: Use time_t for passing and returning time offsetsPeter Maydell
The functions qemu_get_timedate() and qemu_timedate_diff() take and return a time offset as an integer. Coverity points out that means that when an RTC device implementation holds an offset as a time_t, as the m48t59 does, the time_t will get truncated. (CID 1507157, 1517772). The functions work with time_t internally, so make them use that type in their APIs. Note that this won't help any Y2038 issues where either the device model itself is keeping the offset in a 32-bit integer, or where the hardware under emulation has Y2038 or other rollover problems. If we missed any cases of the former then hopefully Coverity will warn us about them since after this patch we'd be truncating a time_t in assignments from qemu_timedate_diff().)

2023-06-01block: add blk_io_plug_call() APIStefan Hajnoczi
Introduce a new API for thread-local blk_io_plug() that does not traverse the block graph. The goal is to make blk_io_plug() multi-queue friendly. Instead of having block drivers track whether or not we're in a plugged section, provide an API that allows them to defer a function call until we're unplugged: blk_io_plug_call(fn, opaque). If blk_io_plug_call() is called multiple times with the same fn/opaque pair, then fn() is only called once at the end of the function - resulting in batching. This patch introduces the API and changes blk_io_plug()/blk_io_unplug(). blk_io_plug()/blk_io_unplug() no longer require a BlockBackend argument because the plug state is now thread-local. Later patches convert block drivers to blk_io_plug_call() and then we can finally remove .bdrv_co_io_plug() once all block drivers have been converted.
