Subject: [RFC PATCH 29/38] arm_mpam: resctrl: Call resctrl_init() on platforms that can support resctrl
Date: Fri, 5 Dec 2025 21:58:52 +0000 [thread overview]
Message-ID: <20251205215901.17772-30-james.morse@arm.com> (raw)
In-Reply-To: <20251205215901.17772-1-james.morse@arm.com>
Now that MPAM links against resctrl, call resctrl_init() to register
the filesystem and setup resctrl's strutures.
