2021-05-02Do not include cpu.h if it's not really necessaryThomas Huth
Stop including cpu.h in files that don't need it. Signed-off-by: Thomas Huth <thuth@redhat.com> Message-Id: <20210416171314.2074665-4-thuth@redhat.com> Signed-off-by: Laurent Vivier <laurent@vivier.eu>
2019-08-16Clean up inclusion of sysemu/sysemu.hMarkus Armbruster
In my "build everything" tree, changing sysemu/sysemu.h triggers a recompile of some 5400 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Almost a third of its inclusions are actually superfluous. Delete them. Downgrade two more to qapi/qapi-types-run-state.h, and move one from char/serial.h to char/serial.c. hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and stubs/semihost.c define variables declared in sysemu/sysemu.h without including it. The compiler is cool with that, but include it anyway. This doesn't reduce actual use much, as it's still included into widely included headers. The next commit will tackle that.

2018-03-08s390x/sclp: clean up sclp masksClaudio Imbrenda
Introduce an sccb_mask_t to be used for SCLP event masks instead of just unsigned int or uint32_t. This will allow later to extend the mask with more ease.

2017-10-06s390x/sclp: mark sclp-cpu-hotplug as non-usercreatableCornelia Huck
A TYPE_SCLP_CPU_HOTPLUG device for handling cpu hotplug events is already created by the sclp event facility. Adding a second TYPE_SCLP_CPU_HOTPLUG device via -device sclp-cpu-hotplug creates an ambiguity in raise_irq_cpu_hotplug(), leading to a crash once a cpu is hotplugged. To fix this, disallow creating a sclp-cpu-hotplug device manually.

2015-09-07sclp/s390: rework sclp cpu hotplug device notificationDavid Hildenbrand
Let's get rid of this strange local variable + irq logic and work directly on the QOM. (hint: what happens if two such devices are created?) We could introduce proper QOM class + state for the cpu hotplug device, however that would result in too much overhead for a simple "trigger_signal" function. Also remove one unnecessary class function initialization.
