[PATCH 00/13] Allow HMAT configuration
Heterogeneous Memory Attribute Table describes links between NUMA nodes
(what's the bandwidth and/or latency between two nodes and/or their side
caches). This enables guests to fine tune their performance.
Michal Prívozník (13):
qemuxml2xmltest: Add "numatune-distance" test case
conf: Move and rename virDomainParseScaledValue()
numa_conf: Drop CPU from name of two functions
qemu_command: Rename qemuBuildNumaArgStr()
qemuBuildMachineCommandLine: Drop needless check
numa_conf: Make virDomainNumaSetNodeCpumask() return void
Allow NUMA nodes without vCPUs
conf: Parse and format HMAT
conf: Validate NUMA HMAT configuration
numa: expose HMAT APIs
qemu: Introduce QEMU_CAPS_NUMA_HMAT capability
qemu: Build HMAT command line
news: Document HMAT addition
