Subject: [PATCH v1 1/6] perf pmus: Fix name comparisons on 32-bit systems
Date: Sat, 31 Aug 2024 00:04:10 -0700 [thread overview]
Message-ID: <20240831070415.506194-2-irogers@google.com> (raw)
In-Reply-To: <20240831070415.506194-1-irogers@google.com>
The hex PMU suffix maybe 64-bit but the comparisons were "unsigned
long" or 32-bit on 32-bit systems. This was causing the "PMU name
comparison" test to fail in a 32-bit build.
