Subject: [PATCH v4 3/8] selftests/resctrl: Remove bw_report and bm_type from main()
Date: Thu, 31 Aug 2023 14:08:38 +0300 [thread overview]
Message-ID: <20230831110843.26719-4-ilpo.jarvinen@linux.intel.com> (raw)
In-Reply-To: <20230831110843.26719-1-ilpo.jarvinen@linux.intel.com>
bw_report is always set to "reads" and bm_type is set to "fill_buf" but
is never used.
Set bw_report directly to "reads" in MBA/MBM test and remove bm_type.
