Subject: [PATCH v1 2/5] perf build: Don't add NO_AUXTRACE if missing feature-get_cpuid
Date: Sun, 9 Nov 2025 17:31:49 -0800 [thread overview]
Message-ID: <20251110013152.3099080-3-irogers@google.com> (raw)
In-Reply-To: <20251110013152.3099080-1-irogers@google.com>
The intel-pt code dependent on __get_cpuid is no longer present so
remove the feature test in the Makefile.config.
