In my "build everything" tree, changing sysemu/reset.h triggers a
recompile of some 2600 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).
The main culprit is hw/hw.h, which supposedly includes it for
convenience.
Include sysemu/reset.h only where it's needed. Touching it now
recompiles less than 200 objects.

The PL031 RTC tracks the difference between the guest RTC
and the host RTC using a tick_offset field. For migration,
however, we currently always migrate the offset between
the guest and the vm_clock, even if the RTC clock is not
the same as the vm_clock; this was an attempt to retain
migration backwards compatibility.
Unfortunately this results in the RTC behaving oddly across
a VM state save and restore -- since the VM clock stands still
across save-then-restore, regardless of how much real world
time has elapsed, the guest RTC ends up out of sync with the
host RTC in the restored VM.
Fix this by migrating the raw tick_offset. To retain migration
compatibility as far as possible, we have a new property
migrate-tick-offset; by default this is 'true' and we will
migrate the true tick offset in a new subsection; if the
incoming data has no subsection we fall back to the old
vm_clock-based offset information, so old->new migration
compatibility is preserved. For complete new->old migration
compatibility, the property is set to 'false' for 4.0 and
earlier machine types (this will only affect 'virt-4.0'
and below, as none of the other pl031-using machines are
versioned).

Like most of the v7M memory mapped system registers, the systick
registers are accessible to privileged code only and user accesses
must generate a BusFault. We implement that for registers in
the NVIC proper already, but missed it for systick since we

If the host decrements the counter register that results in a negative
delta. This is then passed to muldiv64 which only handles unsigned
numbers resulting in bogus results.
This fix ensures the delta being operated on is positive.
Test case: kexec a kernel using aspeed_timer and it will freeze on the
second bootup when the kernel initializes the timer. With this patch
that no longer happens and the timer appears to run OK.

The Linux kernel driver was updated in commit 4451d3f59f2a
("clocksource/drivers/fttmr010: Fix set_next_event handler) to fix an
issue observed on hardware:
> RELOAD register is loaded into COUNT register when the aspeed timer
> is enabled, which means the next event may be delayed because timer
> interrupt won't be generated until <0xFFFFFFFF - current_count +
> cycles>.
When running under Qemu, the system appeared "laggy". The guest is now
scheduling timer events too regularly, starving the host of CPU time.
This patch modifies the timer model to attempt to schedule the timer
expiry as the guest requests, but if we have missed the deadline we
re interrupt and try again, which allows the guest to catch up.
Provides expected behaviour with old and new guest code.

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)

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.

The generated qapi_event_send_FOO() take an Error ** argument. They
can't actually fail, because all they do with the argument is passing it
to functions that can't fail: the QObject output visitor, and the
@qmp_emit callback, which is either monitor_qapi_event_queue() or
event_test_emit().
Drop the argument, and pass &error_abort to the QObject output visitor
and @qmp_emit instead.

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.

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.

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

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

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.

In some cases, the guest can observe the wrong ordering of UIP and
interrupts. This can happen if the VCPU exit is timed like this:
iothread VCPU
... wait for interrupt ...
t-100ns read register A
t wake up, take BQL
t+100ns update_in_progress
return false
return UIP=0
trigger interrupt
The interrupt is late; the VCPU expected the falling edge of UIP to
happen after the interrupt. update_in_progress is already trying to
cover this case by latching UIP if the timer is going to fire soon,
and the fix is documented in the commit message for commit 56038ef623
("RTC: Update the RTC clock only when reading it", 2012-09-10). It
cannot be tested with qtest, because its timing of interrupts vs. reads
is exact.
However, the implementation was incorrect because UIP cmos_ioport_read
cleared register A instead of leaving that to rtc_update_timer. Fixing
the implementation of cmos_ioport_read to match the commit message,
however, breaks the "uip-stuck" test case from the previous patch.
To fix it, skip update timer optimizations if UIP has been latched.

When a timer is enabled before a reload value is set, the controller
waits for a reload value to be set before starting decrementing. This
fix tries to cover that case by changing the timer expiry only when
a reload value is valid.

There are two issues in current code:
1) If the period is changed by re-configuring RegA, the coalesced
irq will be scaled to reflect the new period, however, it
calculates the new interrupt number like this:
s->irq_coalesced = (s->irq_coalesced * s->period) / period;
There are some clocks will be lost if they are not enough to
be squeezed to a single new period that will cause the VM clock
slower
In order to fix the issue, we calculate the interrupt window
based on the precise clock rather than period, then the clocks
lost during period is scaled can be compensated properly
2) If periodic_timer_update() is called due to RegA reconfiguration,
i.e, the period is updated, current time is not the start point
for the next periodic timer, instead, which should start from the
last interrupt, otherwise, the clock in VM will become slow
This patch takes the clocks from last interrupt to current clock
into account and compensates the clocks for the next interrupt,
especially if a complete interrupt was lost in this window, the
time can be caught up by LOST_TICK_POLICY_SLEW

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.

commit 33cd52b5d7 unset
cannot_instantiate_with_device_add_yet in TYPE_SYSBUS, making all
sysbus devices appear on "-device help" and lack the "no-user"
flag in "info qdm".
To fix this, we can set user_creatable=false by default on
TYPE_SYS_BUS_DEVICE, but this requires setting
user_creatable=true explicitly on the sysbus devices that
actually work with -device.
Fortunately today we have just a few has_dynamic_sysbus=1
machines: virt, pc-q35-*, ppce500, and spapr.
virt, ppce500, and spapr have extra checks to ensure just a few
device types can be instantiated:
* virt supports only TYPE_VFIO_CALXEDA_XGMAC, TYPE_VFIO_AMD_XGBE.
* ppce500 supports only TYPE_ETSEC_COMMON.
* spapr supports only TYPE_SPAPR_PCI_HOST_BRIDGE.
This patch sets user_creatable=true explicitly on those 4 device
classes.
Now, the more complex cases:
pc-q35-*: q35 has no sysbus device whitelist yet (which is a
separate bug). We are in the process of fixing it and building a
sysbus whitelist on q35, but in the meantime we can fix the
"-device help" and "info qdm" bugs mentioned above. Also, despite
not being strictly necessary for fixing the q35 bug, reducing the
list of user_creatable=true devices will help us be more
confident when building the q35 whitelist.
xen: We also have a hack at xen_set_dynamic_sysbus(), that sets
has_dynamic_sysbus=true at runtime when using the Xen
accelerator. This hack is only used to allow xen-backend devices
to be dynamically plugged/unplugged.
This means today we can use -device with the following 22 device
types, that are the ones compiled into the qemu-system-x86_64 and
qemu-system-i386 binaries:
* allwinner-ahci
* amd-iommu
* cfi.pflash01
* esp
* fw_cfg_io
* fw_cfg_mem
* generic-sdhci
* hpet
* intel-iommu
* ioapic
* isabus-bridge
* kvmclock
* kvm-ioapic
* kvmvapic
* SUNW,fdtwo
* sysbus-ahci
* sysbus-fdc
* sysbus-ohci
* unimplemented-device
* virtio-mmio
* xen-backend
* xen-sysdev
This patch adds user_creatable=true explicitly to those devices,
temporarily, just to keep 100% compatibility with existing
behavior of q35. Subsequent patches will remove
user_creatable=true from the devices that are really not meant to
user-creatable on any machine, and remove the FIXME comment from
the ones that are really supposed to be user-creatable. This is
being done in separate patches because we still don't have an
obvious list of devices that will be whitelisted by q35, and I
would like to get each device reviewed individually.

cannot_instantiate_with_device_add_yet was introduced by commit
efec3dd631 to replace no_user. It was
supposed to be a temporary measure.
When it was introduced, we had 54
cannot_instantiate_with_device_add_yet=true lines in the code.
Today (3 years later) this number has not shrunk: we now have
57 cannot_instantiate_with_device_add_yet=true lines. I think it
is safe to say it is not a temporary measure, and we won't see
the flag go away soon.
Instead of a long field name that misleads people to believe it
is temporary, replace it a shorter and less misleading field:
user_creatable.

The i.MX timer device can be reset by writing to the SWR bit
of the CR register. This has to behave differently from hard
(power-on) reset because it does not reset all of the bits
in the CR register.
We were incorrectly implementing soft reset and hard reset
the same way, and in addition had a logic error which meant
that we were clearing the bits that soft-reset is supposed
to preserve and not touching the bits that soft-reset clears.
This was not correct behaviour for either kind of reset.
Separate out the soft reset and hard reset code paths, and
correct the handling of reset of the CR register so that it
is correct in both cases.

- Fixes counter value preservation after stopping the timer

Some of the timer devices may behave differently from what ptimer
provides. Introduce ptimer policy feature that allows ptimer users to
change default and wrong timer behaviour, for example to continuously
trigger periodic timer when load value is equal to "0".

The interval timer is similar to the CP0 Count/Compare timer within
each processor. The difference is the GIC_SH_COUNTER register is global
to the system so that all processors have the same time reference.
To ease implementation, all VPs are having its own QEMU timer but sharing
global settings and registers such as GIC_SH_CONFIG.COUTNSTOP and
GIC_SH_COUNTER.
MIPS GIC Interval Timer does support upto 64 bits of Count register but
in this implementation it is limited to 32 bits only.

In various Freescale SOCs, the GPT timers can be configured to select
its input clock.
Depending on the SOC the set of available input clocks may vary.
The actual single GPT definition was no good enough and because of it
booting the sabrelite board with a i.MX6DL device tree would fail
because of an incorrect input clock definition for the i.MX6DL SOC.
This patch fixes the i.MX6DL boot failure by adding the ability to
define a different set of input clocks depending on the considered SOC.
A different class has been defined for i.MX25, i.MX31 and i.MX6 each with
its specific set of input clocks.
The patch has been tested by booting KZM, i.MX25 PDK, i.MX6Q sabrelite
and i.MX6DL sabrelite.

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.

Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef. Since then, we've moved to include qemu/osdep.h
everywhere. Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h. That's in excess of
100KiB of crap most .c files don't actually need.
Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h. Include qapi/error.h in .c files that need it and don't
get it now. Include qapi-types.h in qom/object.h for uint16List.
Update scripts/clean-includes accordingly. Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h
comment quoted above similarly.
This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third. Unfortunately, the number depending on
qapi-types.h shrinks only a little. More work is needed for that one.

Signed integer overflow in C is undefined behaviour, and the compiler
is at liberty to assume it can never happen and optimize accordingly.
In particular, the subtractions in hpet_time_after() and hpet_time_after64()
were causing OSX clang to optimize the code such that it was prone to
hangs and complaints about the main loop stalling (presumably because
we were spending all our time trying to service very high frequency
HPET timer callbacks). The clang sanitizer confirms the UB:
hw/timer/hpet.c:119:26: runtime error: signed integer overflow: -2146967296 - 2147003978 cannot be represented in type 'int'
Fix this by doing the subtraction as an unsigned operation and then
converting to signed for the comparison.

hpet defines a clock period in femtoseconds but
then converts it to nanoseconds to use the internal
timers.
We can define the period in nanoseconds and use it
directly, this allows to remove muldiv64().
We only need to convert the period to femtoseconds
to put it in internal hpet capability register.

Commit e0cf11f31c ("timer: Use a single
definition of NSEC_PER_SEC for the whole codebase") renamed
NANOSECONDS_PER_SECOND to NSEC_PER_SEC.
On Mac OS X there is a <dispatch/time.h> system header which also
defines NSEC_PER_SEC. This causes compiler warnings.
Let's use the old name instead. It's longer but it doesn't clash.

The running timer can't be stopped because timer control code just
doesn't handle disabling the timer. Fix it by deleting the timer if
the enable bit is cleared.
The timer won't start periodic ticking if a ONE-SHOT -> PERIODIC mode
change happens after a one-shot tick was completed. Fix it by
re-starting ticking if the timer isn't ticking right now.
To avoid code churning, these two fixes are squashed in one commit.

When loading a VM from a snapshot or migration, clock changes can cause
the periodic timer to stall or loop rapidly.
qemu-timer has a reset notifier mechanism that is used to avoid timer
stalls or loops if the host clock changes while the VM is running when
using QEMU_CLOCK_HOST. However, when loading a snapshot or migration,
qemu-timer is initialized and fires the reset notifier before
mc146818rtc is initialized and has registered its reset handler. In
addition, this mechanism isn't used when using QEMU_CLOCK_REALTIME,
which might also change when loading a snapshot or migration.
To correct that problem, this commit resets the periodic timer after
loading from a snapshot or migration if the clock has either jumped
backward or has jumped forward by more than the clock jump limit that
is used by the reset notifier code in qemu-timer.

The mc146818rtc driver exposes the current RTC date and time via the "date"
property in QOM (which is also aliased to the machine's "rtc-time"
property). Currently it uses a custom visitor function rtc_get_date to
do this.
This patch introduces new helpers to the QOM core to expose struct tm
valued properties via a getter function, so that this functionality can be
more easily duplicated in other RTC implementations.

We commonly use the error API like this:
err = NULL;
foo(..., &err);
if (err) {
goto out;
}
bar(..., &err);
Every error source is checked separately. The second function is only
called when the first one succeeds. Both functions are free to pass
their argument to error_set(). Because error_set() asserts no error
has been set, this effectively means they must not be called with an
error set.
The qapi-generated code uses the error API differently:
// *errp was initialized to NULL somewhere up the call chain
frob(..., errp);
gnat(..., errp);
Errors accumulate in *errp: first error wins, subsequent errors get
dropped. To make this work, the second function does nothing when
called with an error set. Requires non-null errp, or else the second
function can't see the first one fail.
This usage has also bled into visitor tests, and two device model
object property getters rtc_get_date() and balloon_stats_get_all().
With the "accumulate" technique, you need fewer error checks in
callers, and buy that with an error check in every callee. Can be
nice.
However, mixing the two techniques is confusing. You can't use the
"accumulate" technique with functions designed for the "check
separately" technique. You can use the "check separately" technique
with functions designed for the "accumulate" technique, but then
error_set() can't catch you setting an error more than once.
Standardize on the "check separately" technique for now, because it's
overwhelmingly prevalent.

After commit 767adce2d, they are redundant. This way we don't assign them
except when needed. Once there, there were lots of cases where the ".fields"
indentation was wrong:
.fields = (VMStateField []) {
and
.fields = (VMStateField []) {
Change all the combinations to:
.fields = (VMStateField[]){
The biggest problem (apart from aesthetics) was that checkpatch complained
when we copy&pasted the code from one place to another.

The TCSR register has only 11 valid bits. This is now used by the
linux kernel to auto-detect endianness, and causes Linux 3.15-rc1
and later to hang when run under qemu-microblaze. Mask valid bits
before writing the register to solve the problem.

Don't enable a HPET timer if HPET is disabled
Detect pthread_setname_np at configure time
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
A HPET timer can be started when HPET is not yet
enabled. This will not generate an interrupt
to the guest, but causes problems when HPET is later
enabled.
A timer that is created and expires at least once before
HPET is enabled will have an initialized comparator based
on a hpet_offset of 0 (uninitialized). When HPET is
enabled, hpet_set_timer() is called a second time, which
modifies the timer expiry to a time based on the
difference between current ticks (measured with the
newly initialized hpet_offset) and the timer's
comparator (which was generated before hpet_offset was
initialized). This results in a long period of no HPET
timer ticks.
When this occurs with a CentOS 5.x guest, the guest
may not receive timer interrupts during its narrow
timer check window and panic on boot.

The GPTIMER uses 32-bit registers. Use a 64-bit operation to get the
ptimer count, otherwise we end up with a count of 0 for GPTIMER counter
values of 0xffffffff.
Use the GPTIMER counter value for tracing to avoid an overflow of the
32-bit value passed to trace_grlib_gptimer_enable().

The sun4m architecture has one 'system' timer and one timer per CPU.
The CPU timers can be configured in two modes:
* 22 bits Counter/Timer. Periodic interrupts.
* 54 bits User timer. For profiling. In this mode, the Run/Stop bit
controls the timer.
The run/stop bit controls the timer only when it is in "User" mode, but
its state shall be persistent.

device_add plugs devices into suitable bus. For "real" buses, that
actually connects the device. For sysbus, the connections need to be
made separately, and device_add can't do that. The device would be
left unconnected, and could not possibly work.
Quite a few, but not all sysbus devices already set
cannot_instantiate_with_device_add_yet in their class init function.
Set it in their abstract base's class init function
