MMIO class

MMIO wrapper functions for the Linux userspace /dev/mem device.

Constructors

MMIO.new(int base, int size)

Maps the region of physical memory specified by the base physical address and size in bytes, using the default /dev/mem memory character device.

MMIO.advanced(int base, int size, String path)

Map the region of physical memory specified by the base physical address and size in bytes, using the specified memory character device path.

MMIO.isolate(String json)

Duplicates an existing MMIO from a JSON string. This special constructor is used to transfer an existing MMIO to an other isolate.

read8(int offset) → int

Reads 8-bits from mapped physical memory, starting at the specified byte offset, relative to the base address the MMIO handle was opened with.

setHandle(int handle) → void

override

toJson() → String

override

toString() → String

A string representation of this object.

inherited

write(int offset, List<int> data) → void

operator [](int i) → int

Fast access for MMIO.read32

operator []=(int i, int value) → void

Fast access for MMIO.write32

Static Methods

getMMIOerrorCode(int value) → MMIOerrorCode

Converts the native error code value to MMIOerrorCode.
