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

Hi all, The notes from today's call can be found at: https://github.com/OpenAMP/openamp-system-reference/wiki/OpenAMP-System-Ref… When I tried to add the notes to the usual page, it wouldn't render, so I think that page got too long.

Action items: * Bill will publish the notes & share the recording from the Virtio spin-off call * Bill to discuss w/ Mathieu about joining the AMP BOF * Bill & Arnaud to reply on doc data structures thread from Tammy * Arnaud will look at Zephyr for what could be leveraged for automatic checking of pull requests for Doxygen-compatible comments * [DONE] Nathalie: Make a copy of Dec deck & share to rest of group as editors * Here is the BOF deck working document: https://docs.google.com/presentation/d/1dKGGgLGFWYTeS_pJ4HBqPB1fwq2070-KzoS… * Nathalie: Find out call-in capability for Session Room 1 * Tammy will submit a pull request for the input parameters mods (Separate commits for libs & apps & tests. OK to submit in same pull request) @hnagalla@ti.com<mailto:hnagalla@ti.com> and @Nishanth Menon<mailto:nm@ti.com>: Please email me directly with the google account that you use for work & I can add you to the Google Drive folder where we store the System Reference work-in-progress documents.

Proposal for Updating Doxygen Comments within OpenAMP for Consistent Documentation of Data Structures

by Leino, Tammy

Hello All, As per the discussion last week in the OpenAMP System Reference call, here is my proposal for updating the Doxygen comments for data structures. I would like to target these changes for the April 2023 release. Existing problems with data structure documentation formatting: ------------------------------------------------------------------------------------ 1 - Data structure member descriptions are not being generated in documentation 2 - In place where description should be, there is only a line number and file reference Proposed changes for structure updates: ----------------------------------------------------- 1- Update OpenAMP code to add Doxygen comments for member descriptions to display properly. Current definition of rpmsg_endpoint: ++++++++++++++++++++++++++++ /** * struct rpmsg_endpoint - binds a local rpmsg address to its user * @name: name of the service supported * @rdev: pointer to the rpmsg device * @addr: local address of the endpoint * @dest_addr: address of the default remote endpoint binded. * @cb: user rx callback, return value of this callback is reserved * for future use, for now, only allow RPMSG_SUCCESS as return value. * @ns_unbind_cb: end point service unbind callback, called when remote * ept is destroyed. * @node: end point node. * @priv: private data for the driver's use * * In essence, an rpmsg endpoint represents a listener on the rpmsg bus, as * it binds an rpmsg address with an rx callback handler. */ struct rpmsg_endpoint { char name[RPMSG_NAME_SIZE]; struct rpmsg_device *rdev; uint32_t addr; uint32_t dest_addr; rpmsg_ept_cb cb; rpmsg_ns_unbind_cb ns_unbind_cb; struct metal_list node; void *priv; }; Proposed updates to rpmsg_endpoint: +++++++++++++++++++++++++++++ Comment descriptions should be column-aligned. Copy/paste caused problems. /** * struct rpmsg_endpoint - binds a local rpmsg address to its user * * In essence, an rpmsg endpoint represents a listener on the rpmsg bus, as * it binds an rpmsg address with an rx callback handler. */ struct rpmsg_endpoint { char name[RPMSG_NAME_SIZE]; /** Name of the service supported */ struct rpmsg_device *rdev; /** Pointer to the rpmsg device */ uint32_t addr; /** Local address of the endpoint */ uint32_t dest_addr; /** Address of the default remote endpoint binded */ rpmsg_ept_cb cb; /** User rx callback, return value of this callback is reserved for future use, for now, only allow RPMSG_SUCCESS as return value */ rpmsg_ns_unbind_cb ns_unbind_cb; /** Endpoint service unbind callback, called when remote ept is destroyed */ struct metal_list node; /** Endpoint node */ void *priv; /** Private data for the driver's use */ }; 2 - Update Doxyfile to remove line number / file from description ------------------------------------------------------------------------------------- Updates to Doxyfile to remove line number reference from data structure parameters: +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ # If the SOURCE_BROWSER tag is set to YES then a list of source files will be # generated. Documented entities will be cross-referenced with these sources. # # Note: To get rid of all source code in the generated output, make sure that # also VERBATIM_HEADERS is set to NO. # The default value is: NO. SOURCE_BROWSER = NO
