r4575ae0 r0bf59cf 284 284 set of support routines. 285 285 286 @section Interrupt Delay Profiling 287 288 The RTEMS profiling needs support by the BSP for the interrupt delay times. In 289 case profiling is enabled via the RTEMS build configuration option 290 @code{--enable-profiling} (in this case the pre-processor symbol 291 @code{RTEMS_PROFILING} is defined) a BSP may provide data for the interrupt 292 delay times. The BSP can feed interrupt delay times with the 293 @code{_Profiling_Update_max_interrupt_delay()} function 294 (@code{#include <rtems/score/profiling.h>}). For an example please have a look 295 at @code{c/src/lib/libbsp/sparc/leon3/clock/ckinit.c}. 296 286 297 @section Programmable Interrupt Controller API 287 298 -

r4575ae0 r0bf59cf 363 363 @end itemize 364 364 365 @section Interrupt Profiling 366 367 The RTEMS profiling needs support by the CPU port for the interrupt entry and 368 exit times. In case profiling is enabled via the RTEMS build configuration 369 option @code{--enable-profiling} (in this case the pre-processor symbol 370 @code{RTEMS_PROFILING} is defined) the CPU port may provide data for the 371 interrupt entry and exit times of the outer-most interrupt. The CPU port can 372 feed interrupt entry and exit times with the 373 @code{_Profiling_Outer_most_interrupt_entry_and_exit()} function 374 (@code{#include <rtems/score/profiling.h>}). For an example please have a look 375 at @code{cpukit/score/cpu/arm/arm_exc_interrupt.S}. 376 365 377 @c 366 378 @c
