Virtio convergence: IPC using virtio MMIO transport

by Arnaud POULIQUEN

Hello, As discussed during the meeting. Nicolas (intern in ST) is working on a POC for the interprocessor commination based on VIRTIO MMIO. The purpose of the POC is to be able to access from Linux to an I2C bus managed by the coprocessor. Hardware: - a stm32mp157F DK board - a Nucleo shield ISK01A2 with a set of sensors, connected on the I2C bus - 2 SSD1306 displays connected on the I2C bus Software - The transport layer is the VIRTIO MMIO - The Linux driver used is the virtio-i2c driver - on coprocessor a Zephyr is running that manages one of the displays and provides a bridge to the physical I2C bus Source code: https://github.com/Nicolas62x/linux/commits/I2C-demo https://github.com/Nicolas62x/zephyr_stm32mp1/tree/I2C_demo Please notice that it is only a POC so for time being. The main objective in this first step was to list issues in Linux kernel that should be addressed for the convergence. Nicolas should focus in coming month(s) on the coprocessor part (Zephyr and OpenAMP) to implement a virtio-2c device and the virtio-mmio device part based on Dan's work. Regards, Arnaud ST Restricted

2022 Dec webinar video posted to YouTube with chapters

by Chan King Choy, Nathalie

Hi all, Got our webinar video from Linaro and posted it to the OpenAMP YouTube channel, with a chapter list for easy jumping between sections. I am not sure why the chapters don't appear on the scrubber, maybe due to the video length, but if you go to the description the links in the chapters section allow you to jump. https://youtu.be/R_5DOIvo7tI I'll announce to OpenAMP LinkedIn tomorrow. If anyone spots issues, please let me know. Thanks & regards, Nathalie
