From 1e7860780237bd2be7a1b6a376230bfc93833f17 Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Fri, 5 Sep 2008 22:04:42 +0000 Subject: 2008-09-05 Joel Sherrill * bsp_howto/clock.t: The Shared Memory Driver no longer requires the special IOCTL in Clock_control. This was a hack which has existed since before the Classic API Timer Manager was implemented. All implementations of and references to Clock_control were removed. --- doc/bsp_howto/clock.t | 28 +++------------------------- 1 file changed, 3 insertions(+), 25 deletions(-) (limited to 'doc/bsp_howto') diff --git a/doc/bsp_howto/clock.t b/doc/bsp_howto/clock.t index 69b16e154b..c6d46d4756 100644 --- a/doc/bsp_howto/clock.t +++ b/doc/bsp_howto/clock.t @@ -104,29 +104,7 @@ rtems_isr Clock_isr( rtems_vector_number vector ) @section IO Control -The clock driver must supply a handler for the IO control device driver -entry point.
