This is expected to be reset + * a each tick interrupt. Thus, when the tick handler starts, the counter has + * already wrapped. + * + * HWTC_COUNT_DIRECTION: Should be one of: + * - DIRECTION_INCREMENTING - for hardware timer/counters of incrementing type + * such as the PIT on Atmel AT91SAM7X. + * When the counter value reach HWTC_PERIOD, it is reset to zero and the + * interrupt is signaled. + * - DIRECTION_DECREMENTING - for hardware timer/counters of decrementing type + * such as the SysTick on ARM Cortex M3/M4 chips. + * When the counter value reach 0, it is reset to HWTC_PERIOD and the + * interrupt is signaled. + * + * HWTC_PERIOD: The number of increments or decrements of HWTC_COUNT between + * two tick interrupts. This should preferably be mapped to the reload + * register of the hardware timer, to make it more portable between chips in the + * same family. The macro should in most cases be (reload register + 1). + * + * HWTC_DIVISOR: If the timer frequency is very high, like on the Cortex M chips + * (where the SysTick runs at the core clock frequency), the "differential + * timestamping" used in the recorder will more frequently insert extra XTS + * events to store the timestamps, which increases the event buffer usage. + * In such cases, to reduce the number of XTS events and thereby get longer + * traces, you use HWTC_DIVISOR to scale down the timestamps and frequency. + * Assuming a OS tick rate of 1 KHz, it is suggested to keep the effective timer + * frequency below 65 MHz to avoid an excessive amount of XTS events. Thus, a + * Cortex M chip running at 72 MHZ should use a HWTC_DIVISOR of 2, while a + * faster chip require a higher HWTC_DIVISOR value. + * + * The HWTC macros and vTracePortGetTimeStamp is the main porting issue + * or the trace recorder library.
