build-sys: make HMP source files conditional on have_hmp

2026-08-29T08:07:45+00:00

Exclude all *-hmp-cmds.c files and HMP-only source files from the build when HMP is disabled. Also conditionalise the hmp-commands.hx header generation and the test-hmp qtest.

monitor: tighten monitor_printf*()

2026-08-29T08:07:45+00:00

Rename monitor_printf->monitor_hmp_printf, monitor_vprintf-> monitor_hmp_vprintf, and monitor_printc->monitor_hmp_printc, changing the first parameter from Monitor * to MonitorHMP * to enforce type safety. The implementation is also simplified: monitor_hmp_vprintf now directly calls g_strdup_vprintf + monitor_puts, removing the virtual dispatch via moncls->vprintf. The dev_print() callbacks are temporarily using the MONITOR_HMP(mon) cast, they are fixed in the following commits. Early return in qemu_vprintf() if "hmp" is NULL, relying on monitor_hmp_vprintf() handling NULL case is a bit uncommon.

monitor: change HMPCommand cmd to take MonitorHMP

2026-08-29T08:07:44+00:00

HMP commands are specific to the HMP monitor, so make the cmd function pointer in HMPCommand take MonitorHMP * instead of Monitor *. This strengthens type safety and makes the HMP-specific nature of these handlers explicit. Handler functions are renamed to take MonitorHMP *hmp, with a local Monitor *mon = MONITOR(hmp) added where the body needs the base type. Following patches will drop it, since most functions are HMP specific. Reviewed-by: Daniel P. Berrangé Reviewed-by: Jason J.

monitor: isolate HMP declarations in hmp.h

2026-08-29T08:07:44+00:00

Also rename password & commands with hmp in the name, while at it. Other functions need larger changes which we will take care of next.

monitor: Extract completion declarations to 'monitor/hmp-completion.h'

Many files include "monitor/hmp.h", but few of them really need the completion declarations: move them to a distinct header. Signed-off-by: Philippe Mathieu-Daudé Reviewed-by: Pierrick Bouvier Message-Id: <20260320160811.28611-2-philmd@linaro.org>

rust: add trace crate

2025-10-01T15:22:07+00:00

The trace crate is a minimal container for dependencies of tracepoints (so that they do not have to be imported in all the crates that use tracepoints); it also contains a macro called "include_trace!" that is able to find the right include file from the trace/ directory.

meson: fix Windows build

2025-06-16T17:16:27+00:00

The build fails on Windows. Replace calls to Unix programs like ´cat´, ´sed´ and ´true´ with calls to ´python´ and wrap calls to ´os.path.relpath´ in try-except because it can fail when the two paths are on different drives. Make sure to convert the Windows paths to Unix paths to prevent warnings in generated files.
