Subject: [RFC 3/3] perf: arm_spe: Enable ACPI/Platform automatic module loading
Date: Fri, 8 Feb 2019 18:47:18 -0600 [thread overview]
Message-ID: <20190209004718.3292087-4-jeremy.linton@arm.com> (raw)
In-Reply-To: <20190209004718.3292087-1-jeremy.linton@arm.com>
Lets add the MODULE_TABLE and platform id_table entries so that
the SPE driver can attach to the ACPI platform device created by
the core pmu code.
