What we don't need (and what this patch is making system-only) is the "register a global reset function" API (which is non-functional in user-mode binaries because nothing ever calls the qemu_devices_reset() function to say "run all the hooks", so it makes sense not to compile it in). thanks -- PMM

In user emulation, threads -- implemented as CPU -- are created/destroyed, but never reset. There is no point in providing the sysemu/reset handlers there. Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> --- hw/core/meson.build | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
