KrnAddIRQHandler()

Synopsis

void * KrnAddIRQHandler(
         uint32_t irq,
         irqhandler_t * handler,
         void * handlerData,
         void * handlerData2 );

Function

Add a raw hardware IRQ handler to the chain of handlers.

Inputs

num          - hardware-specific IRQ number
handler      - Pointer to a handler function
handlerData,
handlerData2 - User-defined data which is passed to the
               handler.

  Handler function uses a C calling convention and must be
  declared as follows:

  void IRQHandler(void *handlerData, void *handlerData2)

  handlerData and handlerData2 will be values passed to the
  KrnAddExceptionHandler() function.

  There is no return code for the IRQ handler.

Result

An opaque handle that can be used for handler removal or NULL in case
of failure (like unsupported exception number).

KrnGetSystemAttr()

Synopsis

intptr_t KrnGetSystemAttr(
         uint32_t id );

Function

Get value of internal system attributes.
Currently defined attributes are:

  KATTR_Architecture [.G] (char *)        - Name of architecture the kernel built for.

  KATTR_PeripheralBase [.G] IPTR   - IO Base address for ARM peripherals

Inputs

id - ID of the attribute to get

Result

Value of the attribute

KrnScheduleCPU()

Synopsis

void KrnScheduleCPU(
         void * cpu_mask );

Function

Run task scheduling sequence on all CPUs given in the cpu_mask

Inputs

None

Result

None

Notes

This entry point directly calls task scheduling routine
in supervisor mode. It neither performs any checks of caller status
nor obeys interrupt enable state.

This function is safe to call only from within user mode.
This function is considered internal, and not meant to be called
by user's software.
