Re: [libvirt] [resend v2 0/7] Support cache tune in libvirt

This series patches are for supportting CAT featues, which also called cache tune in libvirt. First to expose cache information which could be tuned in capabilites XML. Then add new domain xml element support to add cacahe bank which will apply on this libvirt domain. This series patches add a util file `resctrl.c/h`, an interface to talk with linux kernel's sys fs. There are still some TODOs such as expose new public interface to get free cache information. Some discussion about this feature support can be found from: https://www.redhat.com/archives/libvir-list/2017-January/msg00644.html Eli Qiao (7): Resctrl: Add some utils functions Resctrl: expose cache information to capabilities Resctrl: Add new xml element to support cache tune Resctrl: Add private interface to set cachebanks Qemu: Set cache banks Resctrl: enable l3code/l3data Resctrl: Make sure l3data/l3code are pairs docs/schemas/domaincommon.rng | 41 ++ include/libvirt/virterror.h | 1 + src/Makefile.am | 1 + src/conf/capabilities.c | 56 +++ src/conf/capabilities.h | 23 + src/conf/domain_conf.c | 154 +++++++ src/conf/domain_conf.h | 18 + src/libvirt_private.syms | 10 + src/qemu/qemu_capabilities.c | 68 +++ src/qemu/qemu_driver.c | 4 + src/qemu/qemu_process.c | 11 + src/util/virerror.c | 1 + src/util/virresctrl.c | 1019 +++++++++++++++++++++++++++++++++++++++++ src/util/virresctrl.h | 135 ++++++ 14 files changed, 1542 insertions(+) create mode 100644 src/util/virresctrl.c create mode 100644 src/util/virresctrl.h
