v5 of: https://www.redhat.com/archives/libvir-list/2018-April/msg02029.html diff to v4: - last patch in the original series is split into two, - more tests added - couple of small changes (e.g. s/int/virTristateBool/) Michal Privoznik (7): qemuMonitorJSONGetDeviceProps: Separate props processing qemu_monitor: Introduce qemuMonitorGetObjectProps qemu_capabilities: Introduce QEMU_CAPS_QOM_LIST_PROPERTIES qemu_capabilities: Introduce QEMU_CAPS_OBJECT_MEMORY_FILE_DISCARD conf: Move virDomainMemtune formatting into a separate function conf: Introduce memoryBacking/discard qemu: Implement memoryBacking/discard docs/formatdomain.html.in | 34 +- docs/schemas/cputypes.rng | 5 + docs/schemas/domaincommon.rng | 10 + src/conf/domain_conf.c | 150 +- src/conf/domain_conf.h | 3 + src/conf/numa_conf.c | 27 + src/conf/numa_conf.h | 3 + src/libvirt_private.syms | 1 + src/qemu/qemu_capabilities.c | 22 + src/qemu/qemu_capabilities.h | 4 + src/qemu/qemu_command.c | 27 +- src/qemu/qemu_monitor.c | 13 + src/qemu/qemu_monitor.h | 3 + src/qemu/qemu_monitor_json.c | 89 +- src/qemu/qemu_monitor_json.h | 4 + .../caps_2.12.0.aarch64.replies | 416 +- tests/qemucapabilitiesdata/caps_2.12.0.aarch64.xml | 4 +- .../qemucapabilitiesdata/caps_2.12.0.ppc64.replies | 4454 ++++++++++---------- tests/qemucapabilitiesdata/caps_2.12.0.ppc64.xml | 4 +- .../qemucapabilitiesdata/caps_2.12.0.s390x.replies | 78 +- tests/qemucapabilitiesdata/caps_2.12.0.s390x.xml | 2 + .../caps_2.12.0.x86_64.replies | 804 ++-- tests/qemucapabilitiesdata/caps_2.12.0.x86_64.xml | 4 +- tests/qemuxml2argvdata/hugepages-pages.args | 12 +- tests/qemuxml2argvdata/hugepages-pages.xml | 3 +- tests/qemuxml2argvdata/hugepages-pages3.args | 3 +- tests/qemuxml2argvdata/hugepages-pages3.xml | 4 +- tests/qemuxml2argvdata/hugepages-pages7.args | 3 +- tests/qemuxml2argvdata/hugepages-pages7.xml | 4 +- tests/qemuxml2argvtest.c | 9 +- tests/qemuxml2xmloutdata/hugepages-pages.xml | 3 +- tests/qemuxml2xmloutdata/hugepages-pages3.xml | 4 +- 32 files changed, 3337 insertions(+), 2869 deletions(-) -- 2.16.1
The code that processes list of device properties is going to be reused. Therefore put it into a separate function.

https://bugzilla.redhat.com/show_bug.cgi?id=1480668 QEMU has this new feature memory-backend-file.discard-data=yes which is a nifty optimization. Basically, when qemu is quitting or on memory hotplug it calls munmap() and close() on the file that is backing the memory. However, this does not mean kernel won't stop touching that part of memory. It still might. With this feature enabled we tell kernel: "we don't need this memory nor data stored in it". This makes kernel drop the memory immediately without trying to sync memory with the mapped file. Unfortunately, this cannot be turned on by default because we can't be sure when users really don't care about what happens to data after qemu dies. So it has to be opt-in. As usual, there are three places where one can configure memory attributes. This patch adds the feature to all of them.
