Subject: [RFC PATCH 3/5] kselftests/resctrl: remove unnecessary exclude_idle
Date: Fri, 23 Jan 2026 13:40:29 +0900 [thread overview]
Message-ID: <20260123044034.141247-4-tan.shaopeng@fujitsu.com> (raw)
In-Reply-To: <20260123044034.141247-1-tan.shaopeng@fujitsu.com>
The Linux manual states regarding exclude_idle: "While you can currently
enable this for any event type, it is ignored for all but software events."
Also, it appears exclude_idle is not supported on Arm.
Therefore, remove it.
