Subject: [PATCH v4 1/2] fbcon: store cursor blink interval in fbcon_ops
Date: Mon, 26 Jan 2015 23:11:55 +0000 (UTC)	[thread overview]
Message-ID: <alpine.DEB.2.11.1501262310430.2861@localhost.localdomain> (raw)
In-Reply-To: <alpine.DEB.2.11.1501262305150.2783@localhost.localdomain>

fbcon toggles cursor display state every 200 milliseconds when blinking.
Since users prefer different toggle intervals, prepare to expose the
interval via sysfs by moving it to fbdev_ops and setting the default
to 200 milliseconds.
