Subject: [PATCH 4/4] perf: arm_spe: Enable ACPI/Platform automatic module loading
Date: Fri, 14 Jun 2019 20:09:10 -0500 [thread overview]
Message-ID: <20190615010910.33921-5-jeremy.linton@arm.com> (raw)
In-Reply-To: <20190615010910.33921-1-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.
