[PATCH v1 0/4] RFC CPU Model Comparison via QMP

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is a preview of the CPU comparison (and soon baseline)
patches. Comments are welcome on all aspects, as they will
help guide the development of the baseline implementation.

The first couple of patches simply refactor code. The first
introduces an XML -> CPU def helper to be used to extract
the CPU definition prior to sending it to the comparison
functions. The second patch refactors some of the code from
CPU model expansion to be later used by comparison and
baseline. Currently, only one of the functions from the
refactoring is reused for comparison. The other two will
come into play when baseline is implemented.

The third is the typical "new capability" patch to introduce
query-cpu-model-comparison and test data for s390x.

The last patch implements the qemuMonitorJSON function for
query-cpu-model-comparison and hooks it up to virsh
hypervisor-cpu-compare.

This is posted as an RFC to make sure these patches are set
in the correct direction before tackling the baseline patches.

Thanks!
