[PATCH 0/3] mshv: Debugfs interface for mshv_root

Posted by Nuno Das Neves 2 weeks, 2 days ago

Expose hypervisor, logical processor, partition, and virtual processor
statistics via debugfs. These are provided by mapping 'stats' pages via
hypercall.

Patch #1: Update hv_call_map_stats_page() to return success when
          HV_STATS_AREA_PARENT is unavailable, which is the case on some
          hypervisor versions, where it can fall back to HV_STATS_AREA_SELF
Patch #2: Introduce the definitions needed for the various stats pages
Patch #3: Add mshv_debugfs.c, and integrate it with the mshv_root driver to
          expose the partition and VP stats.

Nuno Das Neves (2):
  mshv: Add definitions for stats pages
  mshv: Add debugfs to view hypervisor statistics

Purna Pavan Chandra Aekkaladevi (1):
  mshv: Ignore second stats page map result failure
