Highlights

  • RPMSG over IVSHMEM with Dual QEMU A53 Zephyr is working and in review

  • Upstream OpenAMP is progressing on native virtio support and restructure to add multiple virtio transports. Multiple external contributors are active.

  • AMD Xilinx Zynqmp rpmsg is released on Linux kernel v6.4 and joins remoteproc support from v6.2. This completes the Epic for Zynqmp upstream.

  • We have started the work for reproducing the ST I2C demo work

  • Attended Xen Summit, and EOSS (Zephyr Dev Summit + ELC + Yocto Dev day)

    • Some Xen developers believe that IO-REQs needed by traditional Virtio will be a problem for safety certified systems. Some also believe that the page grant mechanism may have to be configured out of Xen when trying to achieve the highest safety levels. The need for both of these can be eliminated by using AMD Virtio.

Issues/Changes

  • Travel for Xen and EOSS conferences occupied the last week of June
