Synopsis

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

Function

Register a hardware IRQ handler.

Inputs

irq          - Hardware-specific interrupt number.
handler      - IRQ callback with the signature:
               void IRQHandler(void *handlerData, void *handlerData2);
handlerData  - First argument passed to the callback.
handlerData2 - Second argument passed to the callback.

Result

Opaque handler handle, or NULL if registration fails.

Synopsis

intptr_t KrnGetCPUAttr(
         uint32_t id,
         uint32_t cpu );

Function

Get the value of a per-CPU attribute, for the given CPU.

See rom/kernel/getcpuattr.c for documentation.

Inputs

id  - ID of the attribute to get
cpu - CPU number, 0 .. KrnGetCPUCount() - 1

Result

Value of the attribute, or -1 when the attribute (or the CPU) is
not known.

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

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.
