2019-08-16Clean up inclusion of sysemu/sysemu.hMarkus Armbruster
In my "build everything" tree, changing sysemu/sysemu.h triggers a recompile of some 5400 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Almost a third of its inclusions are actually superfluous. Delete them. Downgrade two more to qapi/qapi-types-run-state.h, and move one from char/serial.h to char/serial.c. hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and stubs/semihost.c define variables declared in sysemu/sysemu.h without including it. The compiler is cool with that, but include it anyway. This doesn't reduce actual use much, as it's still included into widely included headers. The next commit will tackle that.

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 migration/vmstate.h lessMarkus Armbruster
In my "build everything" tree, changing migration/vmstate.h triggers a recompile of some 2700 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 VMStateDescription. The previous commit made that unnecessary. Include migration/vmstate.h only where it's still needed. Touching it now recompiles only some 1600 objects.

2017-03-14hw/misc/imx6_src: Don't crash trying to reset missing CPUsPeter Maydell
Commit 4881658a4b introduced a call to arm_get_cpu_by_id(), and Coverity noticed that we weren't checking that it didn't return NULL (CID 1371652). Normally this won't happen (because all 4 CPUs are expected to exist), but it's possible the user requested fewer CPUs on the command line. Handle this possibility by silently doing nothing, which is the same behaviour as before commit 4881658a4b and also how we handle the other CPU operations (since we ignore the INVALID_PARAM returns from arm_set_cpu_on() and friends). There is a slight behavioural difference to the pre-4881658a4b situation: the "reset this core" bit will remain set rather than not being permitted to be set. The imx6 datasheet is unclear about the behaviour in this odd corner case, so we opt for the simpler code rather than complicated logic to maintain identical behaviour.

2017-02-24hw/misc/imx6_src: defer clearing of SRC_SCR reset bitsAlex Bennée
The arm_reset_cpu/set_cpu_on/set_cpu_off() functions do their work asynchronously in the target vCPUs context. As a result we need to ensure the SRC_SCR reset bits correctly report the reset status at the right time. To do this we defer the clearing of the bit with an async job which will run after the work queued by ARM powerctl functions.

2016-09-22imx: Use 'const char', not 'char const'Peter Maydell
'char const' means the same thing as 'const char', but we use the former in only a handful of places and we use the latter over six thousand times. Switch the imx reg_name() functions to bring them in line with everything else. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
