Doing that lets us do some followup cleanup. (The diffstat looks alarming but is almost all coccinelle automated changes.) virtio-ccw is a simple conversion, because it's a leaf class and no other code interacts with the reset function. So we convert to three-phase and resettable_class_set_parent_phases(). The s390 CPU is trickier, because s390 has its own set of different kinds of reset (the S390_CPU_RESET_* enum values). At the moment we have a single function implementing the reset, which always chains to the parent DeviceClass::reset, and which can be called both from the CPU object's own DeviceClass::reset method and also from other s390 code. I opted to handle this by adding two new S390-CPU-specific reset types to the Resettable ResetType enum. Now instead of having an underlying implementation of reset that is s390-specific and which might be called either directly or via the DeviceClass::reset method, we can implement only the Resettable hold phase method, and have the places that need to trigger an s390-specific reset type do so by calling resettable_reset(). The other option would have been to smuggle in the s390 reset type via, for instance, a field in the CPU state that we set in s390_do_cpu_initial_reset() etc and then examined in the reset method, but doing it this way seems cleaner. The rest of the series is largely cleanup. Some small stuff: * remove the now-unused device_class_set_parent_reset() function * remove some CPU state struct fields in alpha and hppa that were simply unused * fix an accidental comma in xilinx_axidma that confused a Coccinelle script * hw/remote/message.c should not be directly invoking the DeviceClass::reset method There are also patches here which convert devices from directly setting: dc->reset = my_reset_function; to using a function call: device_class_set_legacy_reset(dc, my_reset_function); The conversion is entirely scripted using a coccinelle patch, and it is responsible for the large diffstat here. If people feel this is unnecessary churn I'm open to that argument, but my motivation here is: * it means that people writing device code see the "legacy" word and get a hint that a new QEMU device probably should be using something else (i.e. Resettable) * it makes it easier to find the places in the code that are still using legacy-reset with a simple grep In particular, having done that makes it easier to rename the DeviceState::reset field to DeviceState::legacy_reset, and that in turn is how I found that hw/remote/ was still directly invoking it. The last patch removes device_phases_reset(), which was the part of the reset transition glue that supported "device is reset via the legacy reset method but it is a three-phase device". Now we know there is no way to directly invoke legacy-reset any more, we can drop that bit of glue. (The opposite direction, "device is reset via a three-phase-aware method but only implements the legacy reset method", is still supported.) I am pondering the idea of a further Coccinelle-driven conversion of device_class_set_legacy_reset() calls into three-phase setting of the Resettable hold phase method. This would be a zero behaviour change, but the difficult part will be where we have devices which make direct function calls to their reset function as well as registering it as the reset method; I'm not sure if Coccinelle can do "match functions which are not referenced elsewhere in the file" checks. Note that my testing here has only been "make check" and "make check-avocado", which I know doesn't really exercise reset very heavily. thanks -- PMM Peter Maydell (10): hw/s390/virtio-ccw: Convert to
