* hw/core/ptimer: Support ptimer being disabled by timer callbackPeter Maydell2020-10-271-0/+4
| | | | | | | | | | | | | | | | | In ptimer_reload(), we call the callback function provided by the timer device that is using the ptimer. This callback might disable the ptimer. The code mostly handles this correctly, except that we'll still print the warning about "Timer with delta zero, disabling" if the now-disabled timer happened to be set such that it would fire again immediately if it were enabled (eg because the limit/reload value is zero). Suppress the spurious warning message and the unnecessary repeat-deletion of the underlying timer in this case.

* hw/core/clock: trace clock values in Hz instead of nsLuc Michel2020-10-272-5/+5
| | | | | | | | | | | | | | | | | | | | The nanosecond unit greatly limits the dynamic range we can display in clock value traces, for values in the order of 1GHz and more. The internal representation can go way beyond this value and it is quite common for today's clocks to be within those ranges. For example, a frequency between 500MHz+ and 1GHz will be displayed as 1ns. Beyond 1GHz, it will show up as 0ns. Replace nanosecond periods traces with frequencies in the Hz unit to have more dynamic range in the trace output.

| * hw/core/qdev-clock: add a reference on aliased clocksLuc Michel2020-10-221-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When aliasing a clock with the qdev_alias_clock() function, a new link property is created on the device aliasing the clock. The link points to the aliased clock and use the OBJ_PROP_LINK_STRONG flag. This property is read only since it does not provide a check callback for modifications. The object_property_add_link() documentation stats that with OBJ_PROP_LINK_STRONG properties, the linked object reference count get decremented when the property is deleted. But it is _not_ incremented on creation (object_property_add_link() does not actually know the link). This commit increments the reference count on the aliased clock to ensure the aliased clock stays alive during the property lifetime, and to avoid a double-free memory error when the property gets deleted.

* device-core: use atomic_set on .realized propertyMaxim Levitsky2020-10-121-1/+18
| | | | | | | | | | | | | | | | | | | | | | Some code might race with placement of new devices on a bus. We currently first place a (unrealized) device on the bus and then realize it. As a workaround, users that scan the child device list, can check the realized property to see if it is safe to access such a device. Use an atomic write here too to aid with this. A separate discussion is what to do with devices that are unrealized: It looks like for this case we only call the hotplug handler's unplug callback and its up to it to unrealize the device. An atomic operation doesn't cause harm for this code path though.

* virtio: skip legacy support check on machine types less than 5.1Stefano Garzarella2020-09-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | Commit 9b3a35ec82 ("virtio: verify that legacy support is not accidentally on") added a check that returns an error if legacy support is on, but the device does not support legacy. Unfortunately some devices were wrongly declared legacy capable even if they were not (e.g vhost-vsock). To avoid migration issues, we add a virtio-device property (x-disable-legacy-check) to skip the legacy error, printing a warning instead, for machine types < 5.1.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | clang's C11 atomic_fetch_*() functions only take a C11 atomic type pointer argument. QEMU uses direct types (int, etc) and this causes a compiler error when a QEMU code calls these functions in a source file that also included <stdatomic.h> via a system header file: $ CC=clang CXX=clang++ ./configure ... && make ../util/async.c:79:17: error: address argument to atomic operation must be a pointer to _Atomic type ('unsigned int *' invalid) Avoid using atomic_*() names in QEMU's atomic.h since that namespace is used by <stdatomic.h>. Prefix QEMU's APIs with 'q' so that atomic.h and <stdatomic.h> can co-exist. I checked /usr/include on my machine and searched GitHub for existing "qatomic_" users but there seem to be none. This patch was generated using: $ git grep -h -o '\<atomic\(64\)\?_[a-z0-9_]\+' include/qemu/atomic.h | \ sort -u >/tmp/changed_identifiers $ for identifier in $(</tmp/changed_identifiers); do sed -i "s%\<$identifier\>%q$identifier%g" \ $(git grep -I -l "\<$identifier\>") done I manually fixed line-wrap issues and misaligned rST tables.

* | qom: simplify object_find_property / object_class_find_propertyDaniel P. Berrangé2020-09-222-2/+2
|/ | | | | | | | | | | | | | | | | | | | | | | When debugging QEMU it is often useful to put a breakpoint on the error_setg_internal method impl. Unfortunately the object_property_add / object_class_property_add methods call object_property_find / object_class_property_find methods to check if a property exists already before adding the new property. As a result there are a huge number of calls to error_setg_internal on startup of most QEMU commands, making it very painful to set a breakpoint on this method. Most callers of object_find_property and object_class_find_property, however, pass in a NULL for the Error parameter. This simplifies the methods to remove the Error parameter entirely, and then adds some new wrapper methods that are able to raise an Error when needed. Signed-off-by: Daniel P.
