Subject: [PATCH v5 4/4] perf: arm_spe: Enable ACPI/Platform automatic module loading
Date: Wed, 26 Jun 2019 16:37:18 -0500 [thread overview]
Message-ID: <20190626213718.39423-5-jeremy.linton@arm.com> (raw)
In-Reply-To: <20190626213718.39423-1-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.
