Subject: [PATCH 11/12] perf test: Add unrolled loop tests for coresight aux data
Date: Wed, 15 Dec 2021 16:04:02 +0000	[thread overview]
Message-ID: <20211215160403.69264-11-carsten.haitzler@foss.arm.com> (raw)
In-Reply-To: <20211215160403.69264-1-carsten.haitzler@foss.arm.com>

From: Carsten Haitzler <carsten.haitzler@arm.com>

These tests have large batches of code manually unrolled with macros
to ensure that the processor has to walk through a lot of instructions
and memory for those instructions to generate the coresight aux data.
