From bd63364caa8df38bad2b25b11b2a1b849475cce5 Mon Sep 17 00:00:00 2001 From: Scot Doyle Date: Thu, 26 Mar 2015 13:54:39 +0000 Subject: vt: add cursor blink interval escape sequence Add an escape sequence to specify the current console's cursor blink interval. The interval is specified as a number of milliseconds until the next cursor display state toggle, from 50 to 65535. /proc/loadavg did not show a difference with a one msec interval, but the lower bound is set to 50 msecs since slower hardware wasn't tested. Store the interval in the vc_data structure for later access by fbcon, initializing the value to fbcon's current hardcoded value of 200 msecs.
