/* The thread execution profile kit is designed to track thread execution time
|
||
|
|
based on the hardware timer defined by TX_EXECUTION_TIME_SOURCE and
|
||
|
|
TX_EXECUTION_MAX_TIME_SOURCE below. When the thread's total time reaches
|
||
|
|
the maximum value, it remains there until the time is reset to 0 via a call
|
||
|
|
to tx_thread_execution_time_reset. There are several assumptions to the
|
||
|
|
operation of this kit, as follows:
|
||
|
|
|
||
|
|
1. The TX_EXECUTION_TIME_SOURCE and TX_EXECUTION_MAX_TIME_SOURCE macros are
|
||
|
|
defined to utilize a local hardware time source.
|
||
|
|
|
||
|
|
2. The following routines are called from assembly code:
|
||
|
|
VOID _tx_execution_thread_enter(void);
|
||
|
|
VOID _tx_execution_thread_exit(void);
|
||
|
|
VOID _tx_execution_isr_enter(void);
|
||
|
|
VOID _tx_execution_isr_exit(void);
|
||
|
|
|
||
|
|
3. The ThreadX library must be rebuilt with TX_EXECUTION_PROFILE_ENABLE so
|
||
|
|
the assembly code macros are enabled to call the execution profile routines.
|
||
|
|
|
||
|
|
4. Add tx_execution_profile.c to the application build. */
