Subject: [PATCH v2] KVM: PPC: Kconfig: Enable CONFIG_VPA_PMU with KVM
Date: Mon, 18 May 2026 10:11:49 +0530 [thread overview]
Message-ID: <20260518044150.34632-1-gautam@linux.ibm.com> (raw)
Enable CONFIG_VPA_PMU with KVM to enable its usage. Currently, the
vpa-pmu driver cannot be used since it is not enabled in distro configs.
On fedora kernel 6.13.7, the config option is disabled:
$ cat /boot/config-6.19.12-200.fc43.ppc64le | grep VPA_PMU
# CONFIG_VPA_PMU is not set
Fixes: 176cda0619b6c ("powerpc/perf: Add perf interface to expose vpa counters")
Cc: stable@vger•kernel.org # v6.13+
