From debb00813774c36bd953c2182f26e1681f42bee2 Mon Sep 17 00:00:00 2001 From: richardbarry Date: Tue, 12 Feb 2013 10:09:36 +0000 Subject: [PATCH] Improve QueueSet.c test coverage by reading the queue set from an ISR to force paths through the queue locking and unlocking. Add the FreeRTOS+Trace recorder into the Win32 MSVC demo. Added more functions, including the queue set functions, to the MPU port. git-svn-id: https://svn.code.sf.net/p/freertos/code/trunk@1822 1d2547de-c912-0410-9cb9-b8ca96c0e9e2 --- FreeRTOS/Demo/Common/Minimal/QueueSet.c | 463 ++++++++++------ FreeRTOS/Demo/Common/include/QueueSet.h | 2 +- FreeRTOS/Demo/WIN32-MSVC/FreeRTOSConfig.h | 10 +- .../Demo/WIN32-MSVC/Run-time-stats-utils.c | 143 +++++ .../Trace_Recorder_Configuration/trcConfig.h | 411 +++++++++++++++ .../Trace_Recorder_Configuration/trcPort.h | 492 ++++++++++++++++++ FreeRTOS/Demo/WIN32-MSVC/WIN32.suo | Bin 62976 -> 63488 bytes FreeRTOS/Demo/WIN32-MSVC/WIN32.vcxproj | 9 +- .../Demo/WIN32-MSVC/WIN32.vcxproj.filters | 24 + FreeRTOS/Demo/WIN32-MSVC/main.c | 13 +- FreeRTOS/Source/include/mpu_wrappers.h | 6 + FreeRTOS/Source/include/queue.h | 49 +- .../Source/portable/GCC/ARM_CM3_MPU/port.c | 82 +++ FreeRTOS/Source/queue.c | 215 +++++--- FreeRTOS/Source/tasks.c | 18 +- 15 files changed, 1669 insertions(+), 268 deletions(-) create mode 100644 FreeRTOS/Demo/WIN32-MSVC/Run-time-stats-utils.c create mode 100644 FreeRTOS/Demo/WIN32-MSVC/Trace_Recorder_Configuration/trcConfig.h create mode 100644 FreeRTOS/Demo/WIN32-MSVC/Trace_Recorder_Configuration/trcPort.h diff --git a/FreeRTOS/Demo/Common/Minimal/QueueSet.c b/FreeRTOS/Demo/Common/Minimal/QueueSet.c index 809aff1ed..59dbcd3d2 100644 --- a/FreeRTOS/Demo/Common/Minimal/QueueSet.c +++ b/FreeRTOS/Demo/Common/Minimal/QueueSet.c @@ -67,7 +67,7 @@ */ /* - * Demonstrates the creation an use of queue sets. + * Tests the use of queue sets. * * A receive task creates a number of queues and adds them to a queue set before * blocking on the queue set receive.

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 uiTracePortGetTimeStamp is the main porting issue + * or the trace recorder library.
