2020-09-03hw/m68k: QOMify the mcf5206 system integration moduleThomas Huth
The mcf5206 system integration module should be a proper device. Let's finally QOMify it. Signed-off-by: Thomas Huth <huth@tuxfamily.org> Message-Id: <20200819065201.4045-1-huth@tuxfamily.org>
2020-07-06hw/m68k/mcf5206: Replace remaining hw_error()s by qemu_log_mask()Thomas Huth
hw_error() dumps the CPU state and exits QEMU. This is ok during initial code development (to see where the guest code is currently executing), but it is certainly not the desired behavior that we want to present to normal users, and it can also cause trouble when e.g. fuzzing devices. Thus let's replace these hw_error()s by qemu_log_mask()s instead.

2020-05-30hw/m68k/mcf52xx: Replace hw_error() by qemu_log_mask()Philippe Mathieu-Daudé
hw_error() calls exit(). This a bit overkill when we can log the accesses as unimplemented or guest error. When fuzzing the devices, we don't want the whole process to exit. Replace some hw_error() calls by qemu_log_mask().

All calls to m5206_mbar_read/m5206_mbar_write are used with 'offset = hwaddr & 0x3ff', so we are sure the offset fits in 16-bit.

2019-10-25hw/m68k/mcf5206.c: Switch to transaction-based ptimer APIPeter Maydell
Switch the mcf5206 code away from bottom-half based ptimers to the new transaction-based ptimer API. This just requires adding begin/commit calls around the various places that modify the ptimer state, and using the new ptimer_init() function to create the timer.

2019-10-15ptimer: Rename ptimer_init() to ptimer_init_with_bh()Peter Maydell
Currently the ptimer design uses a QEMU bottom-half as its mechanism for calling back into the device model using the ptimer when the timer has expired. Unfortunately this design is fatally flawed, because it means that there is a lag between the ptimer updating its own state and the device callback function updating device state, and guest accesses to device registers between the two can return inconsistent device state. We want to replace the bottom-half design with one where the guest device's callback is called either immediately (when the ptimer triggers by timeout) or when the device model code closes a transaction-begin/end section (when the ptimer triggers because the device model changed the ptimer's count value or other state). As the first step, rename ptimer_init() to ptimer_init_with_bh(), to free up the ptimer_init() name for the new API. We can then convert all the ptimer users away from ptimer_init_with_bh() before removing it entirely. (Commit created with git grep -l ptimer_init | xargs sed -i -e 's/ptimer_init/ptimer_init_with_bh/' and three overlong lines folded by hand.)

2019-08-16Include qemu/main-loop.h lessMarkus Armbruster
In my "build everything" tree, changing qemu/main-loop.h triggers a recompile of some 5600 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). It includes block/aio.h, which in turn includes qemu/event_notifier.h, qemu/notify.h, qemu/processor.h, qemu/qsp.h, qemu/queue.h, qemu/thread-posix.h, qemu/thread.h, qemu/timer.h, and a few more. Include qemu/main-loop.h only where it's needed. Touching it now recompiles only some 1700 objects. For block/aio.h and qemu/event_notifier.h, these numbers drop from 5600 to 2800. For the others, they shrink only slightly.

2019-08-16Include hw/irq.h a lot lessMarkus Armbruster
In my "build everything" tree, changing hw/irq.h triggers a recompile of some 5400 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). hw/hw.h supposedly includes it for convenience. Several other headers include it just to get qemu_irq and.or qemu_irq_handler. Move the qemu_irq and qemu_irq_handler typedefs from hw/irq.h to qemu/typedefs.h, and then include hw/irq.h only where it's still needed. Touching it now recompiles only some 500 objects.
