Public Methods

MmioView View (zx_off_t off)

Provides a slice view into the mmio.

The returned slice object must not outlive this object.

void ReadBuffer (zx_off_t offs, void * buffer, size_t size)

Read `size` bytes from the MmioBuffer into `buffer`. There are no access width guarantees

when using this operation and must only be used with devices where arbitrary access widths are

supported.
