2019-08-16sysemu: Split sysemu/runstate.h off sysemu/sysemu.hMarkus Armbruster
sysemu/sysemu.h is a rather unfocused dumping ground for stuff related to the system-emulator. Evidence: * It's included widely: in my "build everything" tree, changing sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h, down from 5400 due to the previous two commits). * It pulls in more than a dozen additional headers. Split stuff related to run state management into its own header sysemu/runstate.h. Touching sysemu/sysemu.h now recompiles some 850 objects. qemu/uuid.h also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400 to 4200. Touching new sysemu/runstate.h recompiles some 500 objects. Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also add qemu/main-loop.h.

2019-08-16Include hw/qdev-properties.h lessMarkus Armbruster
In my "build everything" tree, changing hw/qdev-properties.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Many places including hw/qdev-properties.h (directly or via hw/qdev.h) actually need only hw/qdev-core.h. Include hw/qdev-core.h there instead. hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h and hw/qdev-properties.h, which in turn includes hw/qdev-core.h. Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h. While there, delete a few superfluous inclusions of hw/qdev-core.h. Touching hw/qdev-properties.h now recompiles some 1200 objects.

2019-02-17cuda: decrease time delay before raising VIA SR interrupt and remove fast pathMark Cave-Ayland
In order to handle a race condition in the MacOS 9 CUDA driver, a delay was introduced when raising the VIA SR interrupt inspired by similar code in MacOnLinux. During original testing of the MacOS 9 patches it was found that the 30us delay used in MacOnLinux did not work reliably within QEMU, and a value of 300us was required to function correctly. Recent experiments have shown two things: firstly when booting Linux, MacOS 9 and MacOS X the fast path which bypasses the delay is never triggered once the OS kernel is loaded making it effectively useless. Rather than leave this code in place where a guest could potentially enable it by accident and break itself, we might as well just remove it. Secondly the previous reliability issues are no longer present, and this value can be reduced down to 20us with no apparent ill effects. This has the benefit of considerably improving the responsiveness of the ADB keyboard and mouse within the guest.

2018-06-12mos6522: move timer frequency initialisation to mos6522_resetMark Cave-Ayland
The 6522 VIA timer frequency cannot be set by altering registers within the device itself and hence it is a fixed property of the machine. Move the initialisation of the timer frequency to the mos6522 reset function and ensure that any subclasses always call the parent reset function so that it isn't required to store the timer frequency within vmstate_mos6522_timer itself. By moving the frequency initialisation to the device reset function then we find that the realize function for both mos6522 and mos6522_cuda becomes obsolete and can simply be removed.

2018-06-12cuda: embed mos6522_cuda device directly rather than using QOM object linkMark Cave-Ayland
Examining the migration stream it can be seen that the mos6522 device state is being stored separately rather than as part of the CUDA device which is incorrect (and likely to cause issues if another mos6522 device is added to the machine). Resolve this by embedding the mos6522_cuda device directly within the CUDA device rather than using a QOM object link to reference the device separately. Note that we also bump the version in vmstate_cuda to reflect this change: this isn't particularly important for the moment as the Mac machine migration isn't 100% reliable due to issues migrating the timebase under TCG.

2018-02-11cuda: factor out timebase-derived counter value and load timeMark Cave-Ayland
Commit b981289c49 "PPC: Cuda: Use cuda timer to expose tbfreq to guest" altered the timer calculations from those based upon the hardware CUDA clock frequency to those based upon the CPU timebase frequency. In fact we can isolate the differences to 2 simple changes: one to the counter read value and another to the counter load time.

2017-05-23shutdown: Add source information to SHUTDOWN and RESETEric Blake
Time to wire up all the call sites that request a shutdown or reset to use the enum added in the previous patch. It would have been less churn to keep the common case with no arguments as meaning guest-triggered, and only modified the host-triggered code paths, via a wrapper function, but then we'd still have to audit that I didn't miss any host-triggered spots; changing the signature forces us to double-check that I correctly categorized all callers. Since command line options can change whether a guest reset request causes an actual reset vs. a shutdown, it's easy to also add the information to reset requests.

2016-03-22Replaced get_tick_per_sec() by NANOSECONDS_PER_SECONDRutuja Shah
This patch replaces get_ticks_per_sec() calls with the macro NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec() is then removed. This replacement improves the readability and understandability of code. For example, timer_mod(fdctrl->result_timer, qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50)); NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns matches the unit of the expression on the right side of the plus.
