Subject: [kvm-unit-tests patch v6 03/18] x86: pmu: Refine fixed_events[] names
Date: Sat, 14 Sep 2024 10:17:13 +0000	[thread overview]
Message-ID: <20240914101728.33148-4-dapeng1.mi@linux.intel.com> (raw)
In-Reply-To: <20240914101728.33148-1-dapeng1.mi@linux.intel.com>

In SDM the fixed counter is numbered from 0 but currently the
fixed_events names are numbered from 1. It would cause confusion for
users. So Change the fixed_events[] names to number from 0 as well and
keep identical with SDM.
