2018-12-18qmp hmp: Make system_wakeup check wake-up support and run stateDaniel Henrique Barboza
The qmp/hmp command 'system_wakeup' is simply a direct call to 'qemu_system_wakeup_request' from vl.c. This function verifies if runstate is SUSPENDED and if the wake up reason is valid before proceeding. However, no error or warning is thrown if any of those pre-requirements isn't met. There is no way for the caller to differentiate between a successful wakeup or an error state caused when trying to wake up a guest that wasn't suspended. This means that system_wakeup is silently failing, which can be considered a bug. Adding error handling isn't an API break in this case - applications that didn't check the result will remain broken, the ones that check it will have a chance to deal with it. Adding to that, the commit before previous created a new QMP API called query-current-machine, with a new flag called wakeup-suspend-support, that indicates if the guest has the capability of waking up from suspended state. Although such guest will never reach SUSPENDED state and erroring it out in this scenario would suffice, it is more informative for the user to differentiate between a failure because the guest isn't suspended versus a failure because the guest does not have support for wake up at all. All this considered, this patch changes qmp_system_wakeup to check if the guest is capable of waking up from suspend, and if it is suspended. After this patch, this is the output of system_wakeup in a guest that does not have wake-up from suspend support (ppc64): (qemu) system_wakeup wake-up from suspend is not supported by this guest (qemu) And this is the output of system_wakeup in a x86 guest that has the support but isn't suspended: (qemu) system_wakeup Unable to wake up: guest is not in suspended state (qemu) Reported-by: Balamuruhan S <bala24@linux.vnet.ibm.com> Signed-off-by: Daniel Henrique Barboza <danielhb413@gmail.com> Message-Id: <20181205194701.17836-4-danielhb413@gmail.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> Acked-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Michael S.

The UART and timer devices for the stm32f205 were being created with memory regions that were too large. Use the size specified in the chip datasheet.

2018-10-19error: Fix use of error_prepend() with &error_fatal, &error_abortMarkus Armbruster
From include/qapi/error.h: * Pass an existing error to the caller with the message modified: * error_propagate(errp, err); * error_prepend(errp, "Could not frobnicate '%s': ", name); Fei Li pointed out that doing error_propagate() first doesn't work well when @errp is &error_fatal or &error_abort: the error_prepend() is never reached. Since I doubt fixing the documentation will stop people from getting it wrong, introduce error_propagate_prepend(), in the hope that it lures people away from using its constituents in the wrong order. Update the instructions in error.h accordingly. Convert existing error_prepend() next to error_propagate to error_propagate_prepend(). If any of these get reached with &error_fatal or &error_abort, the error messages improve. I didn't check whether that's the case anywhere.

2018-08-23hw/timer/mc146818rtc: Fix introspection problemThomas Huth
There is currently a funny problem with the "mc146818rtc" device: 1) Start QEMU like this: qemu-system-ppc64 -M pseries -S 2) At the HMP monitor, enter "info qom-tree". Note that there is an entry for "/rtc (spapr-rtc)". 3) Introspect the mc146818rtc device like this: device_add mc146818rtc,help 4) Run "info qom-tree" again. The "/rtc" entry is gone now! The rtc_finalize() function of the mc146818rtc device has two bugs: First, it tries to remove a "rtc" property, while the rtc_realizefn() added a "rtc-time" property instead. And second, it should have been done in an unrealize function, not in a finalize function, to avoid that this causes problems during introspection. But since adding aliases to the global machine state should not be done from a device's realize function anyway, let's rather fix this issue by moving the creation of the alias to the code that creates the device (and thus is run from the machine init functions instead), i.e. the mc146818_rtc_init() function for most machines. The prep machines are special, since the mc146818rtc device is created here in the realize function of the i82378 device. Since we certainly don't want to add the alias there, we add it to some code that is called from the ibm_40p_init() machine init function instead. Since the alias is now only created during the machine init, we can remove the object_property_del() completely.

2018-07-09hw/timer/cmsdk-apb-timer: run or stop timer on writes to RELOAD and VALUEPeter Maydell
If the CMSDK APB timer is set up with a zero RELOAD value then it will count down to zero, fire once and then stay at zero. From the point of view of the ptimer system, the timer is disabled; but the enable bit in the CTRL register is still set and if the guest subsequently writes to the RELOAD or VALUE registers this should cause the timer to start counting down again. Add code to the write paths for RELOAD and VALUE so that we correctly restart the timer in this situation. Conversely, if the new RELOAD and VALUE are both zero, we should stop the ptimer.

2018-06-26aspeed/timer: use the APB frequency from the SCUCédric Le Goater
The timer controller can be driven by either an external 1MHz clock or by the APB clock. Today, the model makes the assumption that the APB frequency is always set to 24MHz but this is incorrect. The AST2400 SoC on the palmetto machines uses a 48MHz input clock source and the APB can be set to 48MHz. The consequence is a general system slowdown. The QEMU machines using the AST2500 SoC do not seem impacted today because the APB frequency is still set to 24MHz. We fix the timer frequency for all SoCs by linking the Timer model to the SCU model. The APB frequency driving the timers is now the one configured for the SoC.

The previous commit improved compile time by including less of the generated QAPI headers. This is impossible for stuff defined directly in qapi-schema.json, because that ends up in headers that that pull in everything. Move everything but include directives from qapi-schema.json to new sub-module qapi/misc.json, then include just the "misc" shard where possible. It's possible everywhere, except: * monitor.c needs qmp-command.h to get qmp_init_marshal() * monitor.c, ui/vnc.c and the generated qapi-event-FOO.c need qapi-event.h to get enum QAPIEvent Perhaps we'll get rid of those some other day.

2018-01-16maint: Fix macros with broken 'do/while(0); ' usageEric Blake
The point of writing a macro embedded in a 'do { ... } while (0)' loop (particularly if the macro has multiple statements or would otherwise end with an 'if' statement) is so that the macro can be used as a drop-in statement with the caller supplying the trailing ';'. Although our coding style frowns on brace-less 'if': if (cond) statement; else something else; that is the classic case where failure to use do/while(0) wrapping would cause the 'else' to pair with any embedded 'if' in the macro rather than the intended outer 'if'. But conversely, if the macro includes an embedded ';', then the same brace-less coding style would now have two statements, making the 'else' a syntax error rather than pairing with the outer 'if'. Thus, even though our coding style with required braces is not impacted, ending a macro with ';' makes our code harder to port to projects that use brace-less styles. The change should have no semantic impact. I was not able to fully compile-test all of the changes (as some of them are examples of the ugly bit-rotting debug print statements that are completely elided by default, and I didn't want to recompile with the necessary -D witnesses - cleaning those up is left as a bite-sized task for another day); I did, however, audit that for all files touched, all callers of the changed macros DID supply a trailing ';' at the callsite, and did not appear to be used as part of a brace-less conditional. Found mechanically via: $ git grep -B1 'while (0);' | grep -A1 \\\\ Signed-off-by: Eric Blake <eblake@redhat.com> Acked-by: Cornelia Huck <cohuck@redhat.com> Reviewed-by: Michael S.

2018-01-12hpet: recover timer offset correctlyPavel Dovgalyuk
HPET saves its state by calculating the current time and recovers timer offset using this calculated value. But these calculations include divisions and multiplications. Therefore the timer state cannot be recovered precise enough. This patch introduces saving of the original value of the offset to preserve the determinism of the timer.

2017-09-27migration: pre_save return intDr. David Alan Gilbert
Modify the pre_save method on VMStateDescription to return an int rather than void so that it potentially can fail. Changed zillions of devices to make them return 0; the only case I've made it return non-0 is hw/intc/s390_flic_kvm.c that already had an error_report/return case. Note: If you add an error exit in your pre_save you must emit an error_report to say why.
