Subject: [PATCH 03/13] kernel: Disable IRQ time accounting
Date: Tue, 07 Sep 2021 15:02:45 +0000 [thread overview]
Message-ID: <20210907150255.16564-3-michael.tremer@ipfire.org> (raw)
In-Reply-To: <20210907150255.16564-1-michael.tremer@ipfire.org>
[-- Attachment #1: Type: text/plain, Size: 1589 bytes --]
This feature is now disabled (was disabled on ARM before) as we do not
need it:
"Select this option to enable fine granularity task irq time accounting.
This is done by reading a timestamp on each transitions between softirq
and hardirq state, so there can be a small performance impact."
