rpmsgexport =========== rpmsgexport implements RPMSG_CREATE_EPT_IOCTL for usage in udev rules to automatically create endpoint devices as remoteproc devices are booted. An example of udev-rule that automatically exposes the APPS_RIVA_CTRL channel to user space as the pronto core comes up: ACTION=="add", SUBSYSTEM=="rpmsg", \ KERNEL=="rpmsg_ctrl[0-9]*", \ ATTRS{rpmsg_name}=="pronto", \ RUN+="rpmsgexport /dev/$name APPS_RIVA_CTRL" Which together with the following two udev rules creates a nice directory structure of rpmsg endpoint devices under /dev/rpmsg: SUBSYSTEM=="rpmsg", KERNEL=="rpmsg_ctrl[0-9]*", \ ATTRS{rpmsg_name}=="?*", \ SYMLINK+="rpmsg/$attr{rpmsg_name}/ctrl" SUBSYSTEM=="rpmsg", KERNEL=="rpmsg[0-9]*", \ ATTR{name}=="?*", \ ATTRS{rpmsg_name}=="?*", \ SYMLINK+="rpmsg/$attr{rpmsg_name}/$attr{name}"
