RPMsg Benchmark Figures

Intro

The present page aims to measure the performance of RPMsg for different number of channels and packet and transfer sizes. This is indicative only and it can vary a lot from implementation to implementation, so use it only as a rough guide.

On the

Setup

Setting up the endpoints

Load firmware to SHARC(s)

cd /lib/firmware
echo stop > /sys/class/remoteproc/remoteproc0/state
echo adi_adsp_core1_fw.ldr > /sys/class/remoteproc/remoteproc0/firmware
echo start > /sys/class/remoteproc/remoteproc0/state

Bind 1 channel

rpmsg-bind-chardev -p virtio0.sharc-echo.-1. -n 1 -e 288 -s 100

Bind 8 channels

rpmsg-bind-chardev -p virtio0.sharc-echo.-1. -n 8 -e 288 -s 100

Bind 32 channels
