2020-09-30hw/char/serial: Make 'wakeup' property booleanPhilippe Mathieu-Daudé1-1/+1
Make the "wakeup" property introduced in commit 9826fd597df ("suspend: make serial ports wakeup the guest") a boolean. As we want to reuse the generic serial properties in the ISA model (next commit), expose this property.

Make SerialState a device (the following patches will introduce IO/MM sysbus serial devices) None of the serial_{,mm}_init() callers actually free the returned value (even if they did, it would be quite harmless), so we can change the object allocation at will.

2019-08-16Clean up inclusion of sysemu/sysemu.hMarkus Armbruster1-1/+0
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.

2018-04-26serial-isa: Use MAX_ISA_SERIAL_PORTS instead of MAX_SERIAL_PORTSPeter Maydell1-0/+3
The ISA serial port handling in serial-isa.c imposes a limit of 4 serial ports. This is because we only know of 4 IO port and IRQ settings for them, and is unrelated to the generic MAX_SERIAL_PORTS limit, though they happen to both be set at 4 currently. Use a new MAX_ISA_SERIAL_PORTS wherever that is the correct limit to be checking against.
