Subject: [RFC PATCH 2/5] kselftests/resctrl: enable noncont_cat for MPAM
Date: Fri, 23 Jan 2026 13:40:28 +0900 [thread overview]
Message-ID: <20260123044034.141247-3-tan.shaopeng@fujitsu.com> (raw)
In-Reply-To: <20260123044034.141247-1-tan.shaopeng@fujitsu.com>
Arm(MPAM driver) also supports non-contiguous CBM.
So enable noncont_cat for Arm.
