[Qemu-devel] [PATCH RFC v2 0/8] Introduce QOM CPU and use for ARM

[Andreas Färber]

Hello,

Here's an updated series on incrementally converting CPUState to QOM.

Patch 1 is cherry-picked from Anthony's QOM series 3/4.

Patch 2 rearranges module init for QOM.
Patch 3 add QOM support to the user emulators.

Patch 4 introduces QOM CPU.

Patch 5-8 Derive and start using a QOM CPU for ARM.

Regards,
Andreas

v1 -> v2:

* Cherry-pick Anthony's object_class_foreach() patch.

* Don't introduce extra early_init(), just relocate former MODULE_INIT_DEVICE.
* Provide new type_init() macro to be used instead of device_init().

* Drop processor_init() and MODULE_INIT_CPU in favor of MODULE_INIT_DEVICE.
* Prepare cast macros for CPU.
* Add documentation.

* Fix ARMCPUClass type name (arm-cpu-core -> arm-cpu).
* Add documentation.
* Rename ARMCPUDef to ARMCPUInfo.
* Use a C99-style table for initializing the classes through class_data
  instead of individual class_init functions (suggested by Anthony).
* Prepare reset callback.

* Make ENV_GET_OBJECT() use an inline function for readability.
* Invoke the CPU's reset method from cpu_reset().

* Do feature initialization via table where sensible.
* Add feature flags to ARMCPU as well (suggested by PMM for future tweaking,
  also simplifies load/save a bit) and initialize them from ARMCPUClass.
* Make feature inference work for ARMCPU as well by not passing the ARMCPUClass.
  Use function-local macros to avoid the ugliness of deferencing the features 
pointer.
