[PATCH v3 0/3] Support fd-based KVM stats

Posted by Mark Kanda 2 years, 3 months ago

v3:
- various QMP API enhancements from v2 review [1] [Daniel, Paolo, Igor]
- general cleanup

v2: [Paolo]
- generalize the interface
- add support for querying stat schema and instances
- add additional HMP semantic processing for a few exponent/unit
   combinations (related to seconds and bytes)

This patchset adds QEMU support for querying fd-based KVM stats. The
kernel support was introduced by:

cb082bfab59a ("KVM: stats: Add fd-based API to read binary stats data")
