system: query machines using TYPE_MACHINE

2026-09-03T10:22:32+00:00

We drop the target_machine_typename() we introduced previously, and revert to using TYPE_MACHINE. From there, we'll make sure only the right types are registered at startup time.

monitor: move HMP-specific to monitor-hmp-internal.h

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

Move HMP-specific declarations to its own CONFIG_HMP guarded header. Reviewed-by: Philippe Mathieu-Daudé Reviewed-by: Dr. David Alan Gilbert Signed-off-by: Marc-André Lureau Message-ID: <20260828-qemu-no-hmp-v5-48-9227de146347@redhat.com>

monitor: move monitor_hmp_print*() functions to hmp.c

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

Those functions are only used when CONFIG_HMP, compile them out, and add conditions for the calling code. Reviewed-by: Dr. David Alan Gilbert Signed-off-by: Marc-André Lureau Message-ID: <20260828-qemu-no-hmp-v5-47-9227de146347@redhat.com>

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.

target: guard MonitorDef tables with CONFIG_HMP

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

Guard SysemuCPUOps::monitor_defs field and the per-target MonitorDef arrays with CONFIG_HMP. These tables are only used by HMP 'print' and 'info registers' commands. Note that the #ifdef in hmp.c is not optimal, but will be removed later once the unit is built conditionally.

Guard HMP command implementations with CONFIG_HMP

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

Add #ifdef CONFIG_HMP around all hmp_* function implementations and their HMP-only helpers across subsystems. This covers monitor_register_hmp* callers, hmp_info_* handlers, and HMP-only helper functions like slirp_lookup. To link succesfully, use empty cmds tables in hmp-cmds.c (to be removed once meson build-sys is updated with !hmp support later in the series) Reviewed-by: Jason J. Herne Reviewed-by: Daniel P.

qapi: make HMP-specific schema entries conditional on CONFIG_HMP

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

Make the 'readline' value of MonitorMode and the 'human-monitor-command' command conditional on CONFIG_HMP, so they are only available when HMP support is compiled in.

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: tighten monitor_set_cpu()/get_cpu()

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

These functions access mon_cpu_path, which is a MonitorHMP-specific field. Narrowing their signatures from Monitor* to MonitorHMP* makes the type system enforce what was already true at runtime: every caller is in an HMP context. The expression parser's MONITOR_HMP() casts are safe because it is only reachable from handle_hmp_command(), they will be dropped with later patches.
