/* 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 * calling overhead including passing of arguments. * * * COPYRIGHT (c) 1989-1997. * On-Line Applications Research Corporation (OAR). * * The license and distribution terms for this file may in * the file LICENSE in this distribution or at * http://www.rtems.com/license/LICENSE. * * $Id$ */ /* * These are set to 0 for now. * * 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 0 #define CALLING_OVERHEAD_SHUTDOWN_EXECUTIVE 0 #define CALLING_OVERHEAD_TASK_CREATE 0 #define CALLING_OVERHEAD_TASK_IDENT 0 #define CALLING_OVERHEAD_TASK_START 0 #define CALLING_OVERHEAD_TASK_RESTART 0 #define CALLING_OVERHEAD_TASK_DELETE 0 #define CALLING_OVERHEAD_TASK_SUSPEND 0 #define CALLING_OVERHEAD_TASK_RESUME 0 #define CALLING_OVERHEAD_TASK_SET_PRIORITY 0 #define CALLING_OVERHEAD_TASK_MODE 0 #define CALLING_OVERHEAD_TASK_GET_NOTE 0 #define CALLING_OVERHEAD_TASK_SET_NOTE 0 #define CALLING_OVERHEAD_TASK_WAKE_WHEN 0 #define CALLING_OVERHEAD_TASK_WAKE_AFTER 0 #define CALLING_OVERHEAD_INTERRUPT_CATCH 0 #define CALLING_OVERHEAD_CLOCK_GET 0 #define CALLING_OVERHEAD_CLOCK_SET 0 #define CALLING_OVERHEAD_CLOCK_TICK 0 #define CALLING_OVERHEAD_TIMER_CREATE 0 #define CALLING_OVERHEAD_TIMER_IDENT 0 #define CALLING_OVERHEAD_TIMER_DELETE 0 #define CALLING_OVERHEAD_TIMER_FIRE_AFTER 0 #define CALLING_OVERHEAD_TIMER_FIRE_WHEN 0 #define CALLING_OVERHEAD_TIMER_RESET 0 #define CALLING_OVERHEAD_TIMER_CANCEL 0 #define CALLING_OVERHEAD_SEMAPHORE_CREATE 0 #define CALLING_OVERHEAD_SEMAPHORE_IDENT 0 #define CALLING_OVERHEAD_SEMAPHORE_DELETE 0 #define CALLING_OVERHEAD_SEMAPHORE_OBTAIN 0 #define CALLING_OVERHEAD_SEMAPHORE_RELEASE 0 #define CALLING_OVERHEAD_MESSAGE_QUEUE_CREATE 0 #define CALLING_OVERHEAD_MESSAGE_QUEUE_IDENT 0 #define CALLING_OVERHEAD_MESSAGE_QUEUE_DELETE 0 #define CALLING_OVERHEAD_MESSAGE_QUEUE_SEND 0 #define CALLING_OVERHEAD_MESSAGE_QUEUE_URGENT 0 #define CALLING_OVERHEAD_MESSAGE_QUEUE_BROADCAST 0 #define CALLING_OVERHEAD_MESSAGE_QUEUE_RECEIVE 0 #define CALLING_OVERHEAD_MESSAGE_QUEUE_FLUSH 0 #define CALLING_OVERHEAD_EVENT_SEND 0 #define CALLING_OVERHEAD_EVENT_RECEIVE 0 #define CALLING_OVERHEAD_SIGNAL_CATCH 0 #define CALLING_OVERHEAD_SIGNAL_SEND 0 #define CALLING_OVERHEAD_PARTITION_CREATE 0 #define CALLING_OVERHEAD_PARTITION_IDENT 0 #define CALLING_OVERHEAD_PARTITION_DELETE 0 #define CALLING_OVERHEAD_PARTITION_GET_BUFFER 0 #define CALLING_OVERHEAD_PARTITION_RETURN_BUFFER 0 #define CALLING_OVERHEAD_REGION_CREATE 0 #define CALLING_OVERHEAD_REGION_IDENT 0 #define CALLING_OVERHEAD_REGION_DELETE 0 #define CALLING_OVERHEAD_REGION_GET_SEGMENT 0 #define CALLING_OVERHEAD_REGION_RETURN_SEGMENT 0 #define CALLING_OVERHEAD_PORT_CREATE 0 #define CALLING_OVERHEAD_PORT_IDENT 0 #define CALLING_OVERHEAD_PORT_DELETE 0 #define CALLING_OVERHEAD_PORT_EXTERNAL_TO_INTERNAL 0 #define CALLING_OVERHEAD_PORT_INTERNAL_TO_EXTERNAL 0 #define CALLING_OVERHEAD_IO_INITIALIZE 0 #define CALLING_OVERHEAD_IO_OPEN 0 #define CALLING_OVERHEAD_IO_CLOSE 0 #define CALLING_OVERHEAD_IO_READ 0 #define CALLING_OVERHEAD_IO_WRITE 0 #define CALLING_OVERHEAD_IO_CONTROL 0 #define CALLING_OVERHEAD_FATAL_ERROR_OCCURRED 0 #define CALLING_OVERHEAD_RATE_MONOTONIC_CREATE 0 #define CALLING_OVERHEAD_RATE_MONOTONIC_IDENT 0 #define CALLING_OVERHEAD_RATE_MONOTONIC_DELETE 0 #define CALLING_OVERHEAD_RATE_MONOTONIC_CANCEL 0 #define CALLING_OVERHEAD_RATE_MONOTONIC_PERIOD 0 #define CALLING_OVERHEAD_MULTIPROCESSING_ANNOUNCE 0 #ifdef __cplusplus } #endif #endif
