Subject: [PATCH v2 1/2] perf/arm-cmn: Decouple wp_config registers from filter group number
Date: Thu, 7 Mar 2024 15:09:28 -0800 [thread overview]
Message-ID: <20240307230929.6233-2-ilkka@os.amperecomputing.com> (raw)
In-Reply-To: <20240307230929.6233-1-ilkka@os.amperecomputing.com>
Previously, wp_config0/2 registers were used for primary match group and
wp_config1/3 registers for secondary match group. In order to support
tertiary match group, this patch decouples the registers and the groups.
