From mboxrd@z Thu Jan 1 00:00:00 1970 From: Michael Tremer To: development@lists.ipfire.org Subject: [PATCH 03/13] kernel: Disable IRQ time accounting Date: Fri, 17 Sep 2021 11:42:19 +0000 Message-ID: <20210917114229.10704-3-michael.tremer@ipfire.org> In-Reply-To: <20210917114229.10704-1-michael.tremer@ipfire.org> MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="===============2789447871680193137==" List-Id: --===============2789447871680193137== Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: quoted-printable 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."
