RM46L852: FreeRTOS on RM46 - Missing function in portASM.asm file

Hi,

I'm trying to port FreeRTOS 10 to the RM46, based on what is provided by Halcogen.

One of the problems I'm encountering is MPU support.
To support the MPU, we need to define the following definitions in portmacro.h

- portIS_PRIVILEGED()
- portRAISE_PRIVILEGE()
- portRESET_PRIVILEGE()

Those definitions will be used in the mpu_wrappers.c. For example:

      void MPU_vTaskDelete( TaskHandle_t pxTaskToDelete ) /* FREERTOS_SYSTEM_CALL */
        {
            if( portIS_PRIVILEGED() == pdFALSE )
            {
                portRAISE_PRIVILEGE();
                portMEMORY_BARRIER();

                vTaskDelete( pxTaskToDelete );
                portMEMORY_BARRIER();

                portRESET_PRIVILEGE();
                portMEMORY_BARRIER();
            }
            else
            {
                vTaskDelete( pxTaskToDelete );
            }
        }

While portRAISE_PRIVILEGE is defined in the SWI jump table, xIsPrivileged() and  vResetPrivilege() are not.

The table in question, as defined in portASM.asm

;-------------------------------------------------------------------------------
; SWI Handler, interface to Protected Mode Functions

        .def    vPortSWI
        .asmfunc
vPortSWI
        stmfd   sp!, {r11,r12,lr}
        mrs     r12, spsr
        ands    r12, r12, #0x20
        ldrbne  r12, [lr, #-2]
        ldrbeq  r12, [lr, #-4]
        ldr     r14,  table
        ldr     r12, [r14, r12, lsl #2]
        blx     r12
        ldmfd   sp!, {r11,r12,pc}^

table
        .word    jumpTable

jumpTable
        .word    swiPortYield                 ; 0 - vPortYieldProcessor
        .word   swiRaisePrivilege         ; 1 - xPortRaisePrivilege
        .word   swiPortEnterCritical         ; 2 - vPortEnterCritical
        .word   swiPortExitCritical          ; 3 - vPortExitCritical
        .word   swiPortTaskUsesFPU            ; 4 - vPortTaskUsesFPU
        .word    swiPortDisableInterrupts     ; 5 - vPortDisableInterrupts
        .word    swiPortEnableInterrupts      ; 6 - vPortEnableInterrupts
        .endasmfunc

I need help defining the assembly required to support the xIsPrivileged() and  vResetPrivilege() functions.

Is the TI compiler has a SVC of some sort? A bit like :

    #define portRAISE_PRIVILEGE()    __asm volatile ( "svc %0 \n" ::"i" ( portSVC_RAISE_PRIVILEGE ) : "memory" );
