| * PORT_HWIndependent | |
| * A hardware independent fallback option for event timestamping. Provides low | |
| * resolution timestamps based on the OS tick. | |
| * This may be used on the Win32 port, but may also be used on embedded hardware | |
| * platforms. All time durations will be truncated to the OS tick frequency, | |
| * typically 1 KHz. This means that a task or ISR that executes in less than | |
| * 1 ms get an execution time of zero. | |
| * | |
| * PORT_APPLICATION_DEFINED | |
| * Allows for defining the port macros in other source code files. | |
| * | |
| * PORT_Win32 | |
| * "Accurate" timestamping based on the Windows performance counter for Win32 | |
| * builds. Note that this gives the host machine time, not the kernel time. | |
| * | |
| * Hardware specific ports | |
| * To get accurate timestamping, a hardware timer is necessary. Below are the | |
| * available ports. Some of these are "unofficial", meaning that | |
| * they have not yet been verified by Percepio but have been contributed by | |
| * external developers. They should work, otherwise let us know by emailing | |

| * IRQ_PRIORITY_ORDER | |
| * | |
| * Macro which should be defined as an integer of 0 or 1. | |
| * | |
| * This should be 0 if lower IRQ priority values implies higher priority | |
| * levels, such as on ARM Cortex M. If the opposite scheme is used, i.e., | |
| * if higher IRQ priority values means higher priority, this should be 1. | |
| * | |
| * This setting is not critical. It is used only to sort and colorize the | |
| * interrupts in priority order, in case you record interrupts using | |
| * the vTraceStoreISRBegin and vTraceStoreISREnd routines. | |
| * | |
| ****************************************************************************** | |
| * | |
| * HWTC Macros | |
| * | |
| * These four HWTC macros provides a hardware isolation layer representing a | |
| * generic hardware timer/counter used for driving the operating system tick, | |
| * such as the SysTick feature of ARM Cortex M3/M4, or the PIT of the Atmel | |
| * AT91SAM7X. | |
| * | |
| * HWTC_COUNT: The current value of the counter. 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 OS 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). | |
| * For FreeRTOS, this can in most cases be defined as | |
| * #define HWTC_PERIOD (configCPU_CLOCK_HZ / configTICK_RATE_HZ) | |
| * | |
| * 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. Typically you should not need to change | |
| * the code of vTracePortGetTimeStamp if using the HWTC macros. | |
