b5020cb3d8 Prevent unprivileged task from altering MPU configuration (#227)
This change removes the FreeRTOS System Calls (aka MPU wrappers) for the
following kernel APIs:
- xTaskCreateRestricted
- xTaskCreateRestrictedStatic
- vTaskAllocateMPURegions

A system call allows an unprivileged task to execute a kernel API which
is otherwise accessible to privileged software only. The above 3 APIs
can create a new task with a different MPU configuration or alter the
MPU configuration of an existing task. This an be (mis)used by an
unprivileged task to grant itself access to a region which it does not
have access to.

Removing the system calls for these APIs ensures that an unprivileged
task cannot execute this APIs. If an unprivileged task attempts to
execute any of these API, it will result in a Memory Fault.

ebbe2cf854 Ensure interrupts are enabled at first task start (#214)
Critical sections in FreeRTOS are implemented using the following two
functions:

void vPortEnterCritical( void )
{
    portDISABLE_INTERRUPTS();
    uxCriticalNesting++;
}

void vPortExitCritical( void )
{
    uxCriticalNesting--;

    if( uxCriticalNesting == 0 )
    {
        portENABLE_INTERRUPTS();
    }
}

uxCriticalNesting is initialized to a large value at the start and set
to zero when the scheduler is started (xPortStartScheduler). As a
result, before the scheduler is started, a pair of enter/exit critical
section will leave the interrupts disabled because uxCriticalNesting
will not reach zero in the vPortExitCritical function. This is done to
ensure that the interrupts remain disabled from the time first FreeRTOS
API is called to the time when the scheduler is started. The scheduler
starting code is expected to enure that interrupts are enabled before
the first task starts executing.

Cortex-M33 ports were not enabling interrupts before starting the first
task and as a result, the first task was started with interrupts
disabled. This PR fixes the issue by ensuring that interrupts are
enabled before the first task is started.

82df39764a Xtensa: fix the coproc_area incorrect issue (#117)
* Xtensa: fix the coproc_area incorrect issue

foss-xtensa/amazon-freertos#2 mentioned a issue:
1.
In function pxPortInitialiseStack(StackType_t *pxTopOfStack....)
p = (uint32_t *)(((uint32_t) pxTopOfStack - XT_CP_SIZE) & ~0xf);

In function prvInitialiseNewTask (file: task.c)
pxTopOfStack = (pxStack + (ulStackDepth - 1)) & (~portBYTE_ALIGNMENT_MASK)

So the co-processor area is at
p = (uint32_t *)(((uint32_t)((pxStack + (ulStackDepth - 1)) & (~portBYTE_ALIGNMENT_MASK)) - XT_CP_SIZE) & ~0xf);

2.
In function vPortStoreTaskMPUSettings( .... , StackType_t pxBottomOfStack ...)
xMPUSettings->coproc_area = (StackType_t)((((uint32_t)(pxBottomOfStack + usStackDepth - 1)) - XT_CP_SIZE) & ~0xf);

pxBottomOfStack = pxStack

=> xMPUSettings->coproc_area = (StackType_t*)((((uint32_t)(pxStack+ ulStackDepth - 1)) - XT_CP_SIZE ) & ~0xf);

The p is coproc_area that should be equal to xMPUSettings->coproc_area.

For example, assume pxStack is 0xa0000000, ulStackDepth is 0x2000,
portBYTE_ALIGNMENT_MASK is 0x7f, XT_CP_SIZE is 0x100.

The p = (uint32_t)(((uint32_t)((pxStack + (ulStackDepth - 1)) & (~portBYTE_ALIGNMENT_MASK)) - XT_CP_SIZE) & ~0xf)
      = 0xa0001e80
The xMPUSettings->coproc_area = (StackType_t)((((uint32_t)(pxStack+ usStackDepth - 1)) - XT_CP_SIZE ) & ~0xf)
                              = 0xa0001ef0
Obviously, the p is not equal to the xMPUSettings->coproc_area, which will cause context switching error.

b9748e50ea Xtensa: fix stack overlap coproc_area issue (#118)
In function pxPortInitialiseStack of port.c:
	sp = ( StackType_t * ) ( ( ( UBaseType_t ) ( pxTopOfStack + 1 )  - XT_CP_SIZE - XT_STK_FRMSZ ) & ~0xf );
We assume XT_CP_SIZE is 0xE4, XT_STK_FRMSZ is 0xA0, pxTopOfStack is 0xA0000000, sp is 0x9FFFFE80.
From port.c, we know the frame->a1 as below:
	frame->a1 = ( UBaseType_t ) sp + XT_STK_FRMSZ;  /* physical top of stack frame    */
So frame->a1 is 0x9FFFFF20. Therefore the interrupt stack frame range is 0x9FFFFE80 ~ 0x9FFFFF20.

The coproc_area is: p = ( uint32_t * ) ( ( ( uint32_t ) pxTopOfStack - XT_CP_SIZE ) & ~0xf );
So its value is 0x9FFFFF10. Obviously, the interrupt stack frame overlaps the coproc_area.

db62e30bce Fix missed yield in xTaskResumeFromISR (#207)
If a higher priority task than the currently running task was resumed
using xTaskResumeFromISR and the user chose to ignore the return value
of xTaskResumeFromISR to initiate a context switch using
portYIELD_FROM_ISR, we were not doing the context switch on the next run
of the scheduler. This change fixes this by marking a yield as pending
to ensure that the context switch is performed on the next run of the
scheduler.

5fb26de019 Recently vTaskDelayUntil() was updated to xTaskDelayUntil() because the function now returns a value. The PR didn't make the same change in the MPU port, or update the constants required to include the xTaskDelayUntil() function in the build. (#199)
This PR:
Changes the INCLUDE_vTaskDelayUntil compile time constant to INCLUDE_xTaskDelayUntil.
Updates FreeRTOS.h to ensure backward compatibility for projects that already have INCLUDE_vTaskDelayUntil defined.
Updates the MPU prototypes, wrapper and implementation to use the updated xTaskDelayUntil() function.

Tests to be checked into the FreeRTOS/FreeRTOS repository after this PR.

71be31bb61 xStreamBufferSend() caps the maximum amount of data a stream buffer can send to the maximum capacity of the buffer - however the value to which the length is capped was wrong, and is correct by this check in. Likewise when sending to a message buffer if the send length is too long the block time is set to 0 to ensure the sending task does not wait indefinitely for the impossible send to complete - but the length check was wrong, and is corrected by this check in.

* Posix: Fix no task switching issue if a task ended

When the main function of a task exits, no task switching happened.
This is because all the remaining tasks are waiting on the condition
variable. The fix is to trigger a task switch and mark the exiting
task as "Dying" to be suspened and exited properly from the scheduler.

* Posix: Assert and stop if the Task function returned

* Posix: just assert if a task returned from its main function

61635d5b8b Fix race condition when tracing is enabled (#95)
* Update port.c

I discovered a very snicky and tricky race condition scenario when integrating tracealyzer code into our project.

A little background  on CortexR5 : When the IRQ line (comming from the interrupt controller, to which every peripheral IRQ lines connect) of the processor rises and the IRQ Enable bit in the status register of the CPU permits it, the CPU traps into interrupt mode. Several things happen. First, the CPU finishes the instruction it was performing. Second, it places the content of the CPSR register into the SPSR_irq register. And third, the mode of the CPU is changed to IRQ_Mode and /!\ THE IRQ ENABLE BIT IN CPSR_irq IS AUTOMATICALLY CLEARED /!\. The reason is to ensure that upon landing into IRQ code, we find ourselves automatically in a critical section because we cannot be interrupted again because the bit is cleared. The programmer can, if he wants, re-enable IRQs inside IRQ code itself to allow interrupt nesting. But it has to be wanted and meditated. 


Now, inside portASM.S, at the end of 'FreeRTOS_IRQ_Handler' assembly function, a call to 'vTaskSwitchContextConst' is made if the variable 'ulPortYieldRequired' was set by someone while executing the interrupt. Before branching to that function, a 'CPSID	i' instruction was placed to ensure that interrupts are disabled in case someone re-enabled it. Inside 'vTaskSwitchContext', there is the macro 'traceTASK_SWITCHED_OUT' that gets populated when tracing is enabled. 

The bug is right there.. If the macro is populated and inside that macro there is a matching call to 'ulPortSetInterruptMask' and 'vPortClearInterruptMask', a race condition can occure is there is a OS Tick timer interrupt waiting at the interrupt controller's door. Upon calling 'vTaskSwitchContext', the interrupts are not masked in the interrupt controller, the only barrier against the CPU servicing that tick interrupt while already performing the function is that the IRQ Enable bit cleared. 'ulPortSetInterruptMask' 
does what's its supposed to do, but doesn't take into account the IRQ Enable bit in CPSR. Wheter or not the bit was cleared, the function sets it at the end. When calling the matching 'vPortClearInterruptMask', the function clears the interrupt mask in the interrupt controller. Because the IRQ Enable bit (that was cleared) has been set no matter what in 'ulPortSetInterruptMask', the CPU services the OS Tick Interrupt right away. 

The bug is there : instead of completing the 'vTaskSwitchContext' function, the CPU re-enters the switch context path right after 'traceTASK_SWITCHED_OUT' thus corrupting the CPU state and eventually triggering either an undefined instruction, data or instruction abort.

* Update port.c

Error on my part, this is the right inline asm code to retreive CPSR register

* Update port.c

Forgot an * while writing comment..

55da9591c0 Fix: Two one line fixes, xTaskCheckForTimeOut() and ulTaskGenericNotifyValueClear(). (#82)
ulTaskGenericNotifyValueClear() returned the notification value of the
currently running task, not the target task.  Now it returns the
notification value of the target task.

Some users expected xTaskCheckForTimeOut() to clear the 'last wake time'
value each time a timeout occurred, whereas it only did that in one path.
It now clears the last wake time in all paths that return that a timeout
occurred.

287361091b Allow application to override TEX,S,C and B bits for Flash and RAM (#113)
The TEX,  Shareable (S), Cacheable (C) and Bufferable (B) bits define
the memory type, and where necessary the cacheable and shareable
properties of the memory region.

The default values for these bits, as configured in our MPU ports, are
sometimes not suitable for application. One such example is when the MCU
has a cache, the application writer may not want to mark the memory as
shareable to avoid disabling the cache. This change allows the
application writer to override default vales for TEX, S C and B bits for
Flash and RAM in their FreeRTOSConfig.h. The following two new
configurations are introduced:

- configTEX_S_C_B_FLASH
- configTEX_S_C_B_SRAM

If undefined, the default values for the above configurations are
TEX=000, S=1, C=1, B=1. This ensures backward compatibility.

4383c8fae3 Change the xRunningPrivileged check from "!=true" to "==false" (#109)
The expected behaviour of portIS_PRIVILEGED is:
- return 0 if the processor is not running privileged.
- return 1 if the processor is running privileged.

Some TI ports do not return 1 when the processor is running privileged
causing the following check to fail: if( xRunningPrivileged != pdTRUE )

This commit change the check to: if( xRunningPrivileged == pdFALSE ). It
ensures that the check is successful even on the ports which return incorrect
value from portIS_PRIVILEGED when the processor is running privileged.

b6a43866da Add support for privileged heap to ARMV8-M ports (#85)
If xTaskCreate API is used to create a task, the task's stack is
allocated on heap using pvPortMalloc. This places the task's stack
in the privileged data section, if the heap is placed in the
privileged data section.

We use a separate MPU region to grant a task access to its stack.
If the task's stack is in the privileged data section, this results in
overlapping MPU regions as privileged data section is already protected
using a separate MPU region. ARMv8-M does not allow overlapping MPU
regions and this results in a fault. This commit ensures to not use a
separate MPU region for the task's stack if it lies within the
privileged data section.

Note that if the heap memory is placed in the privileged data section,
the xTaskCreate API cannot be used to create an unprivileged task as
the task's stack will be in the privileged data section and the task
won't have access to it. xTaskCreateRestricted and
xTaskCreateRestrictedStatic API should be used to create unprivileged
tasks.

Before this change each task had a single direct to task notification value and state as described here: https://www.FreeRTOS.org/RTOS-task-notifications.html. After this change each task has an array of task notifications, so more than one task notification value and state per task. The new FreeRTOSConfig.h compile time constant configTASK_NOTIFICATION_ARRAY_ENTRIES sets the number of indexes in the array.

Each notification within the array operates independently - a task can only block on one notification within the array at a time and will not be unblocked by a notification sent to any other array index.

Task notifications were introduced as a light weight method for peripheral drivers to pass data and events to tasks without the need for an intermediary object such as a semaphore - for example, to unblock a task from an ISR when the operation of a peripheral completed. That use case only requires a single notification value. Their popularity and resultant expanded use cases have since made the single value a limitation - especially as FreeRTOS stream and message buffers themselves use the notification mechanism. This change resolves that limitation. Stream and message buffers still use the task notification at array index 0, but now application writers can avoid any conflict that might have with their own use of task notifications by using notifications at array indexes other than 0.

The pre-existing task notification API functions work in a backward compatible way by always using the task notification at array index 0. For each such function there is now an equivalent that is postfixed "Indexed" and takes an additional parameter to specify which index within the array it should operate upon. For example, xTaskNotify() is the original that only operates on array index 0. xTaskNotifyIndexed() is the new function that can operate on any array index.

Test Steps
The update is tested using the Win32 demo (PR to be created in the FreeRTOS/FreeRTOS github repo), which has been updated to build and run a new test file FreeRTOS/Demo/Common/Minimal/TaskNotifyArray.c. The tests in that file are in addition to, not a replacement for those in FreeRTOS/Demo/Common/Minimal/TaskNotify.c.

bac101c988 Fix/clear MIE bit in initial RISC-V mstatus register. (#57)
* fix: CLEAR MIE BIT IN INITIAL RISC-V MSTATUS VALUE
The MIE bit in the RISC-V MSTATUS register is used to globally enable
or disable interrupts.  It is copied into the MPIE bit and cleared
on entry to an interrupt, and then copied back from the MPIE bit on
exit from an interrupt.

When a task is created it is given an initial MSTATUS value that is
derived from the current MSTATUS value with the MPIE bit force to 1,
but the MIE bit is not forced into any state.  This change forces
the MIE bit to 0 (interrupts disabled).

Why:
If a task is created before the scheduler is started the MIE bit
will happen to be 0 (interrupts disabled), which is fine.  If a
task is created after the scheduler has been started the MIE bit
is set (interrupts enabled), causing interrupts to unintentionally
become enabled inside the interrupt in which the task is first
moved to the running state - effectively breaking a critical
section which in turn could cause a crash if enabling interrupts
causes interrupts to nest.  It is only an issue when starting a
newly created task that was created after the scheduler was started.

334de5d8ab Enable ARMv7-M MPU ports to place FreeRTOS kernel code outside of flash (#46)
Problem Description
-------------------
The current flash organization in ARMv7-M MPU ports looks as follows:

__FLASH_segment_start__ ------->+-----------+<----- __FLASH_segment_start__
                                |  Vector   |
                                |   Table   |
                                |     +     |
                                |   Kernel  |
                                |    Code   |
                                +-----------+<-----  __privileged_functions_end__
                                |           |
                                |           |
                                |           |
                                |   Other   |
                                |   Code    |
                                |           |
                                |           |
                                |           |
   __FLASH_segment_end__ ------>+-----------+

The FreeRTOS kernel sets up the following MPU regions:

* Unprivileged Code - __FLASH_segment_start__ to __FLASH_segment_end__.
* Privileged Code - __FLASH_segment_start__ to __privileged_functions_end__.

The above setup assumes that the FreeRTOS kernel code
(i.e. privileged_functions) is placed at the beginning of the flash and,
therefore, uses __FLASH_segment_start__ as the starting location of the
privileged code. This prevents a user from placing the FreeRTOS kernel
code outside of flash (say to an external RAM) and still have vector
table at the beginning of flash (which is many times a hardware
requirement).

Solution
--------
This commit addresses the above limitation by using a new variable
__privileged_functions_start__ as the starting location of the
privileged code. This enables users to place the FreeRTOS kernel code
wherever they choose.

The FreeRTOS kernel now sets up the following MPU regions:

* Unprivileged Code - __FLASH_segment_start__ to __FLASH_segment_end__.
* Privileged Code - __privileged_functions_start__ to __privileged_functions_end__.

As a result, a user can now place the kernel code to an external RAM. A
possible organization is:

                                 Flash              External RAM
                              +------------+        +-----------+<------ __privileged_functions_start__
                              |   Vector   |        |           |
                              |   Table    |        |           |
                              |            |        |           |
__FLASH_segment_start__ ----->+------------+        |   Kernel  |
                              |            |        |    Code   |
                              |            |        |           |
                              |            |        |           |
                              |            |        |           |
                              |   Other    |        |           |
                              |    Code    |        +-----------+<------ __privileged_functions_end__
                              |            |
                              |            |
                              |            |
  __FLASH_segment_end__ ----->+------------+

Note that the above configuration places the vector table in an unmapped
region. This is okay because we enable the background region, and so the
vector table will still be accessible to the privileged code and not
accessible to the unprivileged code (vector table is only needed by the
privileged code).

Backward Compatibility
----------------------
The FreeRTOS kernel code now uses a new variable, namely
__privileged_functions_start__, which needs to be exported from linker
script to indicate the starting location of the privileged code. All of
our existing demos already export this variable and therefore, they will
continue to work.

If a user has created a project which does not export this variable,
they will get a linker error for unresolved symbol
__privileged_functions_start__. They need to export a variable
__privileged_functions_start__ with the value equal to
__FLASH_segment_start__.

90a3584749 portable/GCC/Posix: add new port for Posix (Linux) applications
This is similar to the Windows port, allowing FreeRTOS kernel
applications to run as regular applications on Posix (Linux) systems.

You can use this in a 32-bit or 64-bit application (although there are
dynamic memory allocation trace points that do not support 64-bit
addresses).

Many of the same caveats of running an RTOS on a non-real-time system
apply, but this is still very useful for easy debugging/testing
applications in a simulated environment. In particular, it allows easy
use of tools such as valgrind.

You can call standard library functions from tasks but care must be
taken with any that internally take mutexes or block. This includes
malloc()/free() and many stdio functions (e.g., printf()).

Replacement malloc(), free(), realloc(), and calloc() functions are
provided which are safe. printf() needs to be called with a FreeRTOS
mutex help (or called from only a single task).

Each task is run in its own pthread, which makes debugging with
standard tools (such as GDB) easier backtraces for individual tasks
are available. Threads for non-running tasks are blocked in sigwait().

The stack for each task (thread) is allocated when the thread is
created, and the stack provided during task creation is not used. This
is so the stack has guard pages, to help with detecting stack
overflows.

Task switch is done by resuming the thread for the next task by
sending it the resume signal (SIGUSR1) and then suspending the current
thread.

The timer interrupt uses SIGALRM and care is taken to ensure that the
signal handler runs only on the thread for the current task.

The additional data needed per-thread is stored at the top on the
task's stack.

When a running task is being deleted, its thread is marked it as dying
so when we switch away from it it exits instead of suspending. This
ensures that even if the idle task doesn't run, threads are deleted
which allows for more threads to be created (if many tasks are being
created and deleted in rapid succession).

To further aid debugging, SIGINT (^C) is not blocked inside critical
sections. This allows it to be used break into GDB while in a critical
section. This means that care must be taken with any custom SIGINT
handlers as these are like NMIs.

This is somewhat inspired by an existing port by William Davy
(https://www.freertos.org/FreeRTOS-simulator-for-Linux.html) but it
takes a number of different approaches to make it switch tasks
reliableand there's little similarly with the original implementation.

- Critical sections block scheduling/"interrupts" by blocking signals
  using pthread_sigmask(). This is more expensive than attempting to
  use flags but works reliably and is analogous to the interrupt
  enable/disable on real hardware.

- Care is take to ensure that the SIGALRM handler (for the timer tick)
  is runnable only on the pthread for the running task. This makes
  tasks switches more straight-forward and reliable as we can suspend
  the thread while in the signal handler.

- Task switches save/restore the critical nesting on the stack.

- Only uses a single (SIGUSR1) signal which is ignored and thus GDB's
  default signal handling options won't trap/print on this signal.

- Extra per-thread data is stored on the task's stack, making it
  accessible in O(1) instead of performing a O(n) lookup of the array.

- Uses the task create/delete hooks in a similar way to the Windows
  port, rather than overloading trace points.

e1b98f0b4b This change prevents tickless idle mode potentially sleeping for an extra tick in the corer case that a tick interrupt occurred between the scheduler being suspended and the expected idle time being checked for a second time (within the idle task) - as described by the sequence below. Th change updates eTaskConfirmSleepModeStatus() to specifically check if a tick is pending, and if so, abort entering sleep mode.
+ The idle task decides to enter sleep mode on the following line.
```
if( xExpectedIdleTime >= configEXPECTED_IDLE_TIME_BEFORE_SLEEP )
```

+ The scheduler is suspended, preventing any context switches.

[Potentially a tick interrupt could occur here.  That could happen if other tasks executing consumed a lot of time since the above code line executed.  If a tick interrupt occurs here the interrupt will be entered but the interrupt will not do anything other than increment xPendedTicks.]

+ The expected idle time is checked again.  No context switches can occur now so the code will execute until the scheduler is unsuspended.  Assuming configEXPECTED_IDLE_TIME_BEFORE_SLEEP is set to a sensible value, a tick interrupt won't occur for some time.

+ portSUPPRESS_TICKS_AND_SLEEP() is called.

+ The default implementation of the tickless function calls eTaskConfirmSleep() - which prior to this change does not return eAbortSleep even though xPendedTicks is not 0, and after this change does return eAbortSleep.

Documentation and download available at https://www.FreeRTOS.org/
Changes between FreeRTOS V10.4.2 and FreeRTOS V10.4.3 released December 14 2020
V10.4.3 is included in the 202012.00 LTS release. Learn more at https:/freertos.org/lts-libraries.html
See https://www.FreeRTOS.org/FreeRTOS-V10.4.x.html
+ Changes to improve robustness and consistency for buffer allocation in
the heap, queue and stream buffer.
+ The following functions can no longer be called from unprivileged code.
- xTaskCreateRestricted
- xTaskCreateRestrictedStatic
- vTaskAllocateMPURegions
Changes between FreeRTOS V10.4.1 and FreeRTOS V10.4.2 released November 10 2020
See https://www.FreeRTOS.org/FreeRTOS-V10.4.x.html
+ Fix an issue in the ARMv8-M ports that caused BASEPRI to be masked
between the first task starting to execute and that task making
a FreeRTOS API call.
+ Introduced xTaskDelayUntil(), which is functionally equivalent to
vTaskDelayUntil(), with the addition of returning a value to
indicating whether or not the function placed the calling task into
the Blocked state or not.
+ Update WolfSSL to 4.5.0 and add the FIPS ready demo.
+ Add support for ESP IDF 4.2 to ThirdParty Xtensa port.
+ Re-introduce uxTopUsedPriority to support OpenOCD debugging.
+ Convert most dependent libraries in FreeRTOS/FreeRTOS to submodules.
+ Various general maintenance and improvements to MISRA compliance.
Changes between FreeRTOS V10.4.0 and FreeRTOS V10.4.1 released September 17 2020
See https://www.FreeRTOS.org/FreeRTOS-V10.4.x.html
+ Fixed an incorrectly named parameter that prevented the
ulTaskNotifyTakeIndexed macro compiling, and the name space clash in the
test code that prevented this error causing test failures.
Changes between FreeRTOS V10.3.1 and FreeRTOS V10.4.0 released September 10 2020
See https://www.FreeRTOS.org/FreeRTOS-V10.4.x.html
Major enhancements:
+ Task notifications: Prior to FreeRTOS V10.4.0 each created task had a
single direct to task notification. From FreeRTOS V10.4.0 each task has
an array of notifications. The direct to task notification API has been
extended with API functions postfixed with "Indexed" to enable the API to
operate on a task notification at any array index. See
https://www.freertos.org/RTOS-task-notifications.html for more information.
+ Kernel ports that support memory protection units (MPUs): The ARMv7-M and
ARMv8-M MPU ports now support a privilege access only heap. The ARMv7-M
MPU ports now support devices that have 16 MPU regions, have the ability
to override default memory attributes for privileged code and data
regions, and have the ability to place the FreeRTOS kernel code outside of
the Flash memory. The ARMv8-M MPU ports now support tickless idle mode.
See https://www.freertos.org/FreeRTOS-MPU-memory-protection-unit.html
for more information.
Additional noteworthy updates:
+ Code formatting is now automated to facilitate the increase in
collaborative development in Git. The auto-formated code is not identical
to the original formatting conventions. Most notably spaces are now used
in place of tabs.
+ The prototypes for callback functions (those that start with "Application",
such as vApplicationStackOverflowHook()) are now in the FreeRTOS header
files, removing the need for application writers to add prototypes into
the C files in which they define the functions.
+ New Renesas RXv3 port layer.
+ Updates to the Synopsys ARC code, including support for EM and HS cores,
and updated BSP.
+ Added new POSIX port layer that allows FreeRTOS to run on Linux hosts in
the same way the Windows port layer enables FreeRTOS to run on Windows
hosts.
+ Many other minor optimisations and enhancements. For full details
see https://github.com/FreeRTOS/FreeRTOS-Kernel/commits/master
Changes between FreeRTOS V10.3.0 and FreeRTOS V10.3.1 released February 18 2020

## Getting started
This repository contains FreeRTOS kernel source/header files and kernel ports only. This repository is referenced as a submodule in [FreeRTOS/FreeRTOS](https://github.com/FreeRTOS/FreeRTOS) repository, which contains pre-configured demo application projects under ```FreeRTOS/Demo``` directory.
The easiest way to use FreeRTOS is to start with one of the pre-configured demo application projects. That way you will have the correct FreeRTOS source files included, and the correct include paths configured. Once a demo application is building and executing you can remove the demo application files, and start to add in your own application source files. See the [FreeRTOS Kernel Quick Start Guide](https://www.FreeRTOS.org/FreeRTOS-quick-start-guide.html) for detailed instructions and other useful links.
Additionally, for FreeRTOS kernel feature information refer to the [Developer Documentation](https://www.FreeRTOS.org/features.html), and [API Reference](https://www.FreeRTOS.org/a00106.html).
### Getting help
If you have any questions or need assistance troubleshooting your FreeRTOS project, we have an active community that can help on the [FreeRTOS Community Support Forum](https://forums.freertos.org).

## Repository structure
- The root of this repository contains the three files that are common to
every port - list.c, queue.c and tasks.c. The kernel is contained within these
three files. croutine.c implements the optional co-routine functionality - which
is normally only used on very memory limited systems.
- The ```./portable``` directory contains the files that are specific to a particular microcontroller and/or compiler.
See the readme file in the ```./portable``` directory for more information.
- The ```./include``` directory contains the real time kernel header files.
### Code Formatting
FreeRTOS files are formatted using the "uncrustify" tool. The configuration file used by uncrustify can be found in the [FreeRTOS/FreeRTOS repository](https://github.com/FreeRTOS/FreeRTOS/blob/master/tools/uncrustify.cfg).
### Spelling
*lexicon.txt* contains words that are not traditionally found in an English dictionary. It is used by the spellchecker to verify the various jargon, variable names, and other odd words used in the FreeRTOS code base. If your pull request fails to pass the spelling and you believe this is a mistake, then add the word to *lexicon.txt*.
Note that only the FreeRTOS Kernel source files are checked for proper spelling, the portable section is ignored.
