7 This document describes the rpmsg bus and how to write rpmsg drivers.
14 Modern SoCs typically employ heterogeneous remote processor devices in
17 flavor of real-time OS.
19 OMAP4, for example, has dual Cortex-A9, dual Cortex-M3 and a C64x+ DSP.
20 Typically, the dual cortex-A9 is running Linux in a SMP configuration,
24 Typically AMP remote processors employ dedicated DSP codecs and multimedia
25 hardware accelerators, and therefore are often used to offload CPU-intensive
28 These remote processors could also be used to control latency-sensitive
32 Users of those remote processors can either be userland apps (e.g. multimedia
