* hw/char/serial-{isa, pci}: Alias QDEV properties from generic serial objectPhilippe Mathieu-Daudé2020-09-301-2/+2
| | | | | | | | | | | Instead of overwritting the properties of the generic 'state' object, alias them. Note we can now propagate the "baudbase" property.

| | | | | | | | | | | | | 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.

This is a bad idea: hw/qdev-core.h is widely included. Move the declaration of qdev_add_vm_change_state_handler() to sysemu/sysemu.h, and drop the problematic include from hw/qdev-core.h. Touching sysemu/sysemu.h now recompiles some 1800 objects. qemu/uuid.h also drops from 5400 to 1800. A few more headers show smaller improvement: qemu/notify.h drops from 5600 to 5200, qemu/timer.h from 5600 to 4500, and qapi/qapi-types-run-state.h from 5500 to 5000.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little.
