Calling for agenda: 2026-03-11 OpenAMP System Reference - WARNING EU/NA time zone offset weird weeks!

by Chan King Choy, Nathalie

[Public] [CC OpenAMP board on this one, since proposing EU CRA topic - let me know if you want to join & don't have the meeting invite] Hi all, Reminder for Europe that the appointment will appear in your calendar at a different time than usual, since North America just did our time change over the weekend. Note that Dan can't make it this week @Arnaud POULIQUEN<mailto:arnaud.pouliquen@st.com>: You had suggested that we decide based on # of topics if we should cancel this week due to low volume. What do you think? Please let us know your agenda topics. Here is what I collected so far: * RPMsg IOCTL access without root permissions from Linux userspace<https://lists.openampproject.org/archives/list/openamp-system-reference@lis…> * Discussion on list between @Shah, Tanmay<mailto:tanmay.shah@amd.com>, @Arnaud POULIQUEN<mailto:arnaud.pouliquen@st.com> and @Hatle, Mark<mailto:mark.hatle@amd.com> * EU CRA: I think Dan was interested in being part of this discussion. Some useful resources: * FOSDEM 2026 "Why is the CRA worth a FOSS maintainer's attention?" recording<https://fosdem.org/2026/schedule/event/PFM7TL-panel_why_is_the_cra_worth_a_…> * FOSDEM 2026 "From Minimum Compliance to Meaningful Stewardship" recording<https://fosdem.org/2026/schedule/event/FEJGDD-panel_from_minimum_compliance…> * May 2025 Embedded Recipes talk by Greg KH<https://youtu.be/u44eMQpGlxA?si=JQgdirVeL1_pYU3O> * Bonus: This FOSDEM 2026 presenter did an amazing job at making Erlang's approach to CRA compliance entertaining<https://fosdem.org/2026/schedule/event/JFJV3R-story-of-the-erlang-journey-t…> * But probably the only takeaway for us is that they do have their reports go onto GitHub issues * Recent PRs * https://github.com/OpenAMP/openamp-system-reference/pulls * https://github.com/OpenAMP/openamp-system-reference/pull/94 * Tanmay believes existing doc is not enough, maybe can update the documentation * Tanmay to ping Arnaud when ready for him to review system reference PR94 * https://github.com/OpenAMP/openamp-demo/pulls * No open PRs * https://github.com/OpenAMP/openamp-docs/pulls * PR82 is still in draft state * https://github.com/OpenAMP/open-amp/pulls * Only stale PRs remain * https://github.com/OpenAMP/libmetal/pulls * Only stale PRs remain * Any Zephyr topics? * OpenAMP docs improvement project topics? * 2026 task tracker<https://docs.google.com/spreadsheets/d/1NyVPqvcSmPVu4SjRsFHboyLPdByWo38MIAD…> / individual updates Thanks & regards, Nathalie

RPMsg IOCTL access without root permissions from Linux userspace

by Shah, Tanmay

Hi all, I am working on remoteproc auto-boot feature. While working on this, I realized it should be possible to achieve RPMsg communication without root access given to the user. Existing demos doesn't support it, but I want to open discussion on how that can be achieved. One way discussed was, to use IOCTLS to create RPMSg devices, and I had open issue here: https://github.com/OpenAMP/openamp-system-reference/issues/50 I tried to modify echo_test[1] demo and use IOCTLS instead of accessing devices from sysfs directly, but that still need root access. My goal is to design following workflow for the RPMsg communication with the remote processor: 1. Linux device-tree has auto-boot property enabled. 2. During boot, driver parses auto-boot related properties, loads fw and boots rproc automatically (without user's involvement) 3. After boot, rproc firmware does name service announcement of RPMsg channels. 4. Linux creates RPMsg devices and ept based on above announcement. 5. Userspace apps uses RPMsg ioctls to create ept and rpmsg devices. 6. Userspace apps uses created devices for RPMsg communication with the remote processor. As per my testing, as of now step-5 and step-6 needs root access. Ideally userspace apps should be able to create/read/write/close rpmsg devices without root access (for security purposes). Is there any other way this problem is solved? I appreciate your input. Thank You, Tanmay References: [1] https://github.com/OpenAMP/openamp-system-reference/blob/main/examples/linu…
