Is it so much churn to just rename everything to MACHINE_INIT_PHASE_* and keep phase_check() as is? Or is it because the QAPI-generated names are quite long?

The names were also quite long, required additional line breaks... If this is too much churn I can squash commits. When squashed, I don't see the big difference between just renaming and this approach, pretty much the same lines are modified. I believed it was easier to review without squash. However, if you believe it should rather be just renamed I can do so. > Paolo > >> Signed-off-by: Mirela Grujic <mirela.grujic@greensocs.com> >> --- >> include/hw/qdev-core.h | 2 ++ >> hw/core/machine-qmp-cmds.c | 2 +- >> hw/core/machine.c | 2 +- >> hw/core/qdev.c | 12 +++++++++++- >> hw/pci/pci.c | 2 +- >> hw/usb/core.c | 2 +- >> hw/virtio/virtio-iommu.c | 2 +- >> monitor/hmp.c | 2 +- >> softmmu/qdev-monitor.c | 9 ++++----- >> softmmu/vl.c | 2 +- >> ui/console.c | 2 +- >> 11 files changed, 25 insertions(+), 14 deletions(-) >> >> diff --git a/include/hw/qdev-core.h b/include/hw/qdev-core.h >> index 6e52240d92..5e3c6d4482 100644 >> --- a/include/hw/qdev-core.h >> +++ b/include/hw/qdev-core.h >> @@ -842,5 +842,7 @@ typedef enum MachineInitPhase { >> extern bool phase_check(MachineInitPhase phase); >> extern void phase_advance(MachineInitPhase phase); >> extern MachineInitPhase phase_get(void); >> +extern bool machine_is_initialized(void); >> +extern bool machine_is_ready(void); >> #endif >> diff --git a/hw/core/machine-qmp-cmds.c b/hw/core/machine-qmp-cmds.c >> index 68a942595a..be286882cc 100644 >> --- a/hw/core/machine-qmp-cmds.c >> +++ b/hw/core/machine-qmp-cmds.c >> @@ -149,7 +149,7 @@ HotpluggableCPUList >> *qmp_query_hotpluggable_cpus(Error **errp) >> void qmp_set_numa_node(NumaOptions *cmd, Error **errp) >> { >> - if (phase_check(PHASE_MACHINE_INITIALIZED)) { >> + if (machine_is_initialized()) { >> error_setg(errp, "The command is permitted only before the >> machine has been created"); >> return; >> } >> diff --git a/hw/core/machine.c b/hw/core/machine.c >> index 40def78183..eba046924d 100644 >> --- a/hw/core/machine.c >> +++ b/hw/core/machine.c >> @@ -1239,7 +1239,7 @@ static NotifierList machine_init_done_notifiers = >> void qemu_add_machine_init_done_notifier(Notifier *notify) >> { >> notifier_list_add(&machine_init_done_notifiers, notify); >> - if (phase_check(PHASE_MACHINE_READY)) { >> + if (machine_is_ready()) { >> notify->notify(notify, NULL); >> } >> } >> diff --git a/hw/core/qdev.c b/hw/core/qdev.c >> index 4a4a4d8c52..71906170f9 100644 >> --- a/hw/core/qdev.c >> +++ b/hw/core/qdev.c >> @@ -904,7 +904,7 @@ static void device_initfn(Object *obj) >> { >> DeviceState *dev = DEVICE(obj); >> - if (phase_check(PHASE_MACHINE_READY)) { >> + if (machine_is_ready()) { >> dev->hotplugged = 1; >> qdev_hot_added = true; >> } >> @@ -1155,6 +1155,16 @@ MachineInitPhase phase_get(void) >> return machine_phase; >> } >> +bool machine_is_initialized(void) >> +{ >> + return machine_phase >= PHASE_MACHINE_INITIALIZED; >> +} >> + >> +bool machine_is_ready(void) >> +{ >> + return machine_phase >= PHASE_MACHINE_READY; >> +} >> + >> static const TypeInfo device_type_info = { >> .name = TYPE_DEVICE, >> .parent = TYPE_OBJECT, >> diff --git a/hw/pci/pci.c b/hw/pci/pci.c >> index 8f35e13a0c..19b584c3d1 100644 >> --- a/hw/pci/pci.c >> +++ b/hw/pci/pci.c >> @@ -1071,7 +1071,7 @@ static PCIDevice >> *do_pci_register_device(PCIDevice *pci_dev, >> address_space_init(&pci_dev->bus_master_as, >> &pci_dev->bus_master_container_region, pci_dev->name); >> - if (phase_check(PHASE_MACHINE_READY)) { >> + if (machine_is_ready()) { >> pci_init_bus_master(pci_dev); >> } >> pci_dev->irq_state = 0; >> diff --git a/hw/usb/core.c b/hw/usb/core.c >> index 975f76250a..2ec0dea6a0 100644 >> --- a/hw/usb/core.c >> +++ b/hw/usb/core.c >> @@ -97,7 +97,7 @@ void usb_wakeup(USBEndpoint *ep, unsigned int stream) >> USBDevice *dev = ep->dev; >> USBBus *bus = usb_bus_from_device(dev); >> - if (!phase_check(PHASE_MACHINE_READY)) { >> + if (!machine_is_ready()) { >> /* >> * This is machine init cold plug.

I am just not sure it's such an advantage to replace phase_check with
separate functions. The rename is a constraint of QAPI, so we have to
live with the long names.

You can also use 'prefix':'...' as part of the QAPI 'enum' declaration to pick a shorter name for the C enum (see for example BlkdebugEvent in block-core.json).

Once we define MachineInitPhase in qapi, the generated enumeration constants will be prefixed with the MACHINE_INIT_PHASE_. We need to define the MachineInitPhase enum in qapi in order to add the QMP command that will query current machine init phase. Since in the existing definition of enum MachineInitPhase the enumeration constants are prefixed with PHASE_, there will be a massive find/replace to rename the existing enum constants. We'll do this in 2 phases: 1) hide explicit use of PHASE_ prefixed enums by replacing phase_check(PHASE_MACHINE_INITIALIZED) -> machine_is_initialized() phase_check(PHASE_MACHINE_READY) -> machine_is_ready() 2) rename enums Once 1) and 2) are done MachineInitPhase enum will be generated.
