Subject: [PATCH v2 02/12] ARC: set level of log per CPU during boot to be debug level
Date: Tue, 13 Jun 2017 17:03:46 +0300 [thread overview]
Message-ID: <1497362636-30353-3-git-send-email-noamca@mellanox.com> (raw)
In-Reply-To: <1497362636-30353-1-git-send-email-noamca@mellanox.com>
From: Noam Camus <noamca@mellanox.com>
The reasons are:
1) speeding up boot time, becomes critical for many CPUs machine,
e.g. NPS400 with 4K CPUs
2) shorten kernel log at boot time, again easy to scan for large
scale machines such NPS400
