Subject: [PATCH 0/3] mshv: Debugfs interface for mshv_root
Date: Wed, 3 Dec 2025 09:53:22 -0800 [thread overview]
Message-ID: <1764784405-4484-1-git-send-email-nunodasneves@linux.microsoft.com> (raw)
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

mshv: Ignore second stats page map result failure
