/* coverhd.h * * This include file has defines to represent the overhead associated * with calling a particular directive from C. These are used in the * Timing Test Suite to ignore the overhead required to pass arguments * to directives. On some CPUs and/or target boards, this overhead * is significant and makes it difficult to distinguish internal * RTEMS execution time from that used to call the directive. * This file should be updated after running the C overhead timing * test. Once this update has been performed, the RTEMS Time Test * Suite should be rebuilt to account for these overhead times in the * timing results. * * NOTE: If these are all zero, then the times reported include * all calling overhead including passing of arguments. * * COPYRIGHT (c) 1989-1999. * On-Line Applications Research Corporation (OAR). * * The license and distribution terms for this file may be * found in the file LICENSE in this distribution or at * http://www.OARcorp.com/rtems/license.html. * * $Id: coverhd.h,v 1.2 2001-09-27 12:00:41 chris Exp $ */ /* * Updated for a 25MHz Papyrus by Andrew Bray <andy@i-cubed.co.uk> * * Units are 100ns. * * These numbers are of questionable use, as they are developed by calling * the routine many times, thus getting its entry veneer into the (small) * cache on the 403GA. This in general is not true of the RTEMS timing * tests, which usually call a routine only once, thus having no cache loaded * advantage. * * Whether the directive times are useful after deducting the function call * overhead is also questionable. The user is more interested generally * in the total cost of a directive, not the cost if the procedure call * is inlined! (In general this is not true). * * Andrew Bray 18/08/1995 * */ #ifndef __COVERHD_h #define __COVERHD_h #ifdef __cplusplus extern "C" { #endif #define CALLING_OVERHEAD_INITIALIZE_EXECUTIVE 1 #define CALLING_OVERHEAD_SHUTDOWN_EXECUTIVE 1 #define CALLING_OVERHEAD_TASK_CREATE 3 #define CALLING_OVERHEAD_TASK_IDENT 1 #define CALLING_OVERHEAD_TASK_START 1 #define CALLING_OVERHEAD_TASK_RESTART 1 #define CALLING_OVERHEAD_TASK_DELETE 1 #define CALLING_OVERHEAD_TASK_SUSPEND 1 #define CALLING_OVERHEAD_TASK_RESUME 1 #define CALLING_OVERHEAD_TASK_SET_PRIORITY 1 #define CALLING_OVERHEAD_TASK_MODE 1 #define CALLING_OVERHEAD_TASK_GET_NOTE 1 #define CALLING_OVERHEAD_TASK_SET_NOTE 1 #define CALLING_OVERHEAD_TASK_WAKE_WHEN 4 #define CALLING_OVERHEAD_TASK_WAKE_AFTER 1 #define CALLING_OVERHEAD_INTERRUPT_CATCH 1 #define CALLING_OVERHEAD_CLOCK_GET 4 #define CALLING_OVERHEAD_CLOCK_SET 3 #define CALLING_OVERHEAD_CLOCK_TICK 1 #define CALLING_OVERHEAD_TIMER_CREATE 1 #define CALLING_OVERHEAD_TIMER_IDENT 1 #define CALLING_OVERHEAD_TIMER_DELETE 1 #define CALLING_OVERHEAD_TIMER_FIRE_AFTER 2 #define CALLING_OVERHEAD_TIMER_FIRE_WHEN 5 #define CALLING_OVERHEAD_TIMER_RESET 1 #define CALLING_OVERHEAD_TIMER_CANCEL 1 #define CALLING_OVERHEAD_SEMAPHORE_CREATE 2 #define CALLING_OVERHEAD_SEMAPHORE_IDENT 1 #define CALLING_OVERHEAD_SEMAPHORE_DELETE 1 #define CALLING_OVERHEAD_SEMAPHORE_OBTAIN 1 #define CALLING_OVERHEAD_SEMAPHORE_RELEASE 1 #define CALLING_OVERHEAD_MESSAGE_QUEUE_CREATE 2 #define CALLING_OVERHEAD_MESSAGE_QUEUE_IDENT 1 #define CALLING_OVERHEAD_MESSAGE_QUEUE_DELETE 1 #define CALLING_OVERHEAD_MESSAGE_QUEUE_SEND 1 #define CALLING_OVERHEAD_MESSAGE_QUEUE_URGENT 1 #define CALLING_OVERHEAD_MESSAGE_QUEUE_BROADCAST 1 #define CALLING_OVERHEAD_MESSAGE_QUEUE_RECEIVE 2 #define CALLING_OVERHEAD_MESSAGE_QUEUE_FLUSH 1 #define CALLING_OVERHEAD_EVENT_SEND 1 #define CALLING_OVERHEAD_EVENT_RECEIVE 2 #define CALLING_OVERHEAD_SIGNAL_CATCH 1 #define CALLING_OVERHEAD_SIGNAL_SEND 1 #define CALLING_OVERHEAD_PARTITION_CREATE 3 #define CALLING_OVERHEAD_PARTITION_IDENT 1 #define CALLING_OVERHEAD_PARTITION_DELETE 1 #define CALLING_OVERHEAD_PARTITION_GET_BUFFER 1 #define CALLING_OVERHEAD_PARTITION_RETURN_BUFFER 1 #define CALLING_OVERHEAD_REGION_CREATE 3 #define CALLING_OVERHEAD_REGION_IDENT 1 #define CALLING_OVERHEAD_REGION_DELETE 1 #define CALLING_OVERHEAD_REGION_GET_SEGMENT 2 #define CALLING_OVERHEAD_REGION_RETURN_SEGMENT 1 #define CALLING_OVERHEAD_PORT_CREATE 2 #define CALLING_OVERHEAD_PORT_IDENT 1 #define CALLING_OVERHEAD_PORT_DELETE 1 #define CALLING_OVERHEAD_PORT_EXTERNAL_TO_INTERNAL 1 #define CALLING_OVERHEAD_PORT_INTERNAL_TO_EXTERNAL 2 #define CALLING_OVERHEAD_IO_INITIALIZE 2 #define CALLING_OVERHEAD_IO_OPEN 2 #define CALLING_OVERHEAD_IO_CLOSE 2 #define CALLING_OVERHEAD_IO_READ 2 #define CALLING_OVERHEAD_IO_WRITE 2 #define CALLING_OVERHEAD_IO_CONTROL 2 #define CALLING_OVERHEAD_FATAL_ERROR_OCCURRED 1 #define CALLING_OVERHEAD_RATE_MONOTONIC_CREATE 1 #define CALLING_OVERHEAD_RATE_MONOTONIC_IDENT 1 #define CALLING_OVERHEAD_RATE_MONOTONIC_DELETE 1 #define CALLING_OVERHEAD_RATE_MONOTONIC_CANCEL 1 #define CALLING_OVERHEAD_RATE_MONOTONIC_PERIOD 1 #define CALLING_OVERHEAD_MULTIPROCESSING_ANNOUNCE 1 #ifdef __cplusplus } #endif #endif /* end of include file */
