From 0dd1d44582dd2b39a791aa60f76358ff9bba8cd8 Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Tue, 11 Jan 2000 17:34:20 +0000 Subject: Removed old hack of using Configuration Table entry ticks_per_timeslice being set to 0 to indicate that there should be no Clock Tick. This was used by the Timing Tests to avoid clock tick overhead perturbing execution times. Now the Timing Tests simply leave the Clock Tick Driver out of the Device Driver Table. --- c/src/lib/libcpu/hppa1.1/clock/clock.c | 30 +++++++++++++----------------- 1 file changed, 13 insertions(+), 17 deletions(-) (limited to 'c/src/lib/libcpu/hppa1.1/clock/clock.c') diff --git a/c/src/lib/libcpu/hppa1.1/clock/clock.c b/c/src/lib/libcpu/hppa1.1/clock/clock.c index 256d5bc2ae..7bf177e3d6 100644 --- a/c/src/lib/libcpu/hppa1.1/clock/clock.c +++ b/c/src/lib/libcpu/hppa1.1/clock/clock.c @@ -101,20 +101,18 @@ void Install_clock(rtems_isr_entry clock_isr) Clock_isrs = rtems_configuration_get_milliseconds_per_tick(); - if ( rtems_configuration_get_ticks_per_timeslice() ) { - /* - * initialize the interval here - * First tick is set to right amount of time in the future - * Future ticks will be incremented over last value set - * in order to provide consistent clicks in the face of - * interrupt overhead - */ - - Clock_clicks_interrupt = Clock_read_itimer() + CPU_HPPA_CLICKS_PER_TICK; - set_itimer((rtems_unsigned32) Clock_clicks_interrupt); - - (void) set_vector(clock_isr, HPPA_INTERRUPT_EXTERNAL_INTERVAL_TIMER, 1); - } + /* + * initialize the interval here + * First tick is set to right amount of time in the future + * Future ticks will be incremented over last value set + * in order to provide consistent clicks in the face of + * interrupt overhead + */ + + Clock_clicks_interrupt = Clock_read_itimer() + CPU_HPPA_CLICKS_PER_TICK; + set_itimer((rtems_unsigned32) Clock_clicks_interrupt); + + (void) set_vector(clock_isr, HPPA_INTERRUPT_EXTERNAL_INTERVAL_TIMER, 1); atexit(Clock_exit); } @@ -186,9 +184,7 @@ Clock_isr(rtems_vector_number vector) void Clock_exit(void) { - if ( rtems_configuration_get_ticks_per_timeslice() ) { - (void) set_vector(0, HPPA_INTERRUPT_EXTERNAL_INTERVAL_TIMER, 1); - } + (void) set_vector(0, HPPA_INTERRUPT_EXTERNAL_INTERVAL_TIMER, 1); } /* -- cgit v1.2.3
