Gaurav Aggarwal e058a65b16 Updates to CM3_MPU GCC port
- System calls are now only allowed from kernel code. This change can be turned on
  or off using configENFORCE_SYSTEM_CALLS_FROM_KERNEL_ONLY.
- MPU is disabled before reprogramming it and enabled afterwards to be compliant
  with ARM recommendations.

Richard Barry 066e2bc7d2 Replace portasmHAS_CLINT with configMTIME_BASE_ADDRESS and configMTIMECMP_BASE_ADDRESS definitions in the IAR RISC-V port - portasmHAS_CLIT will still work by deriving the new definitions from the old. 2020-01-09 02:23:51 +00:00
Richard Barry fbb23055cd Replace portasmHAS_CLINT with configMTIME_BASE_ADDRESS and configMTIMECMP_BASE_ADDRESS definitions in the GCC RISC-V port - portasmHAS_CLIT will still work by deriving the new definitions from the old. 2020-01-07 01:14:36 +00:00
Richard Barry eaf9318df8 Add Source/portable/ARMClang file that directs users to the GCC port if they which to use the ARMClang compiler. 2020-01-04 00:14:18 +00:00
Richard Barry e292c67933 Replace the static prvSetupTimerInterrupt() function in the Cortex-M port layers that still used it (other than MPU ports so far) with a weakly defined function call vPortSetupTimerInterrupt() - which allows application writers to override the function with one that uses a different clock. 2019-12-30 21:16:09 +00:00

Yuhui.Zheng 9c0e3fe9f1 Cortex M0 GCC/IAR/Keil ports -- tickless support.
The default portMISSED_COUNTS_FACTOR is set to 45 cycles. User could override this value, if a more accurate count is available.
2019-12-18 09:55:08 +00:00
Richard Barry 46e5937529 Remove guards against __ARMCC_VERSION version numbers that were previously used to avoid compiler warnings in some GCC ARM Cortex ports. 2019-11-21 22:35:21 +00:00
Richard Barry 07622ed3ee Remove driver files that generate compiler warnings from the RISC-V_Renode_Emulator_SoftConsole project.
Update RISC-V ports so the interrupt stack is set to a known value before the scheduler is started if the interrupt stack is statically defined rather than re-using the main.c() stack.
2019-11-18 17:23:14 +00:00
Richard Barry 16639d2d63 Update to the latest atomic.h.
Improve commenting in RISC-V GCC port.
Fix IAR RISC-V port so the first task starts with interrupts enabled.
Add references to third party page ref using newlib with FreeRTOS into the tasks.c file in each place newlib is referenced.
Move the position of the traceTASK_DELETE() trace macro in case of use with a memory allocator that writes over freed memory even when inside a critical section.
Efficiency improvement:  Make sure xTaskIncrementTick() does not return pdTRUE when the scheduler is locked.  This just prevents an unnecessary yield interrupt (unnecessary as it is ignored) when xYieldPending happens to be pdTRUE.

Richard Barry 61a003088d Update RISK-V GCC port to ensure the first task starts with interrupts enabled - previously its interrupts were only enabled after it yielded for the first time. 2019-10-21 04:16:32 +00:00

Richard Barry 973a4f9869 Correct alignment of stack top in RISC-V port when configISR_STACK_SIZE_WORDS is defined to a non zero value. 2019-08-27 15:57:45 +00:00
Richard Barry 7d285f3dcb + Moved the History.txt file from the website git repo into the source code SVN repo.
+ Added xTaskCatchUpTicks() which corrects the tick count value after the application code has held interrupts disabled for an extended period.
+ Updated the xTaskResumeAll() implementation so it uses the new xTaskCatchUpTicks() function mentioned above to unwind ticks that were pended while the scheduler was suspended.
+ Various maintenance on the message buffer, stream buffer and abort delay demos.
+ Change type of uxPendedTicks from UBaseType_t to TickType_t to ensure it has same type as variables it is compared to, and therefore also rename the variable xPendingTicks.
+ Correct spelling mistake within a comment that was common to all the ARMv7-M ports.

Richard Barry 11d9c440b8 Move the 'generic' version of freertos_risc_v_chip_specific_extensions.h back to a sub-directory as having it in the RISC-V port's base directory was causing SoftConsole to pick up the wrong version (for an unknown reason).
