mmi_map_physio

NAME

mmi_map_physio() - Add mapping for module in I/O space

SYNOPSIS

#include "mmi.h"

typedef int (*mmi_access)
     (uint32_t cpu_id, void* obj, uint64_t paddr, bool_t wr, uint32_t size, uint64_t* buf, uint8_t bytemask)

int mmi_map_physio (uint64_t base, uint64_t size, void* obj, mmi_access access)

DESCRIPTION

Creates a mapping for obj at base for size bytes.

CPU I/O space accesses in this range call access, with obj and parameters for the I/O access.

RETURN VALUES

Returns true if successful.

USAGE EXAMPLE

static int
sgc_access(uint32_t cpu_id, void* obj, uint64_t paddr, bool_t wr, uint32_t size, uint64_t* buf)
{
    SerengetiConsole* s = (SerengetiConsole*) obj;
    return s->access(cpu_id, obj, paddr, wr, size, buf);
}

SerengetiConsole::SerengetiConsole()
{
    mmi_map_physio(0x7fff0000000ULL, 0x10000000ULL, this, sgc_access);
}
