Function Documentation

unsigned int SUMT_rtBoardInit

(

SUMT_RT *

rt

)

Initialize the Summit target board hardware.

Initializes the board specific functionallity of a Summit hardware board. The board is mapped into the appropriate bus address and the interrupt configuration is setup.

The board-specific function is resposible for initializing the following members of the rt structure:

base_addr - The base address of shared memory as seen by the Summit controller.
mem_addr - The base address of shared memory as seen by the CPU.
mem_size - The size in bytes of the shared memory.
sum_regs - The local address of the Summit registers.
intr_level - The local interrupt level number.
intr_vector - The local interrupt vector number.

Parameters:

rt

A device descriptor.

Returns:

A CTDB MSG code.
