Open Source Build Environment for OpenAMP

by Ed T. Mooring

Hi all, One of the difficulties I have encountered while trying to get OpenAMP into the Linaro continuous integration loop, as well as while trying to test the GitHub OpenAMP repository code, has been the need to use proprietary tools and environments to build the OpenAMP firmware.This is what I think is needed to solve this problem. Feedback will be welcomed. Goal: A complete open-source development environment for OpenAMP on Linux for Cortex A and bare metal/FreeRTOS on Cortex R. The first use for this is for Jenkins/LAVA testing. Just using a slightly customized version of the Xilinx Yocto build for Linux and OpenAMP turns out to be impractical due to the use of a Xilinx-specific toolchain and the huge size of the resulting image. The second use is for developers who want to work with OpenAMP and the Linux kernel without needing to use a proprietary SDK or tool chain. In fact, with the QEMU Docker container, they wouldn't even need real hardware. To do this requires: Toolchains for the ARM Cortex A and Cortex R. I intend to use the toolchains provided by ARM by default, but the eventual setup should allow the user to switch to other toolchains, such as LLVM or a proprietary one. A Linux root filesystem. I will create this using Yocto and a stripped-down image recipe. The necessary header files and libraries to compile and link the Cortex R5 firmware for Xilinx first (the BSP). Later I want to support other manufacturers as well. A mechanism to update the root file system when the Linux kernel or the OpenAMP binaries and firmware are updated. A way of building bootable images, either for hardware or QEMU. The above two items are part of the standard image build process and will use available open source tools. Something to run the resulting image. This will default to the QEMU Docker image. This should be easier to use for newcomers and facilitate the CI loop. Steps: 1) Shrink the image. This can be done in two stages: a. Build less stuff. The OpenAMP tests don't need full Perl and Python installs, among other things. b. Tune the kernel. There are a lot of modules we don't need. This will also speed up build times considerably. It might even be enough to get the CI loop started. 2) Set up the tooling to create root file systems 3) Set up the tooling to create images 4) Document all the steps required to create and boot an image. 5) Automate all of the above.

OpenAMP Release 2020.01

by Ed Mooring

[copy-pasted from the Google group] This is to announce the release of OpenAMP 2020.01. It's a "catch up" release that incorporates the low-risk changes proposed for OpenAMP/libmetal since the last release. See https://github.com/OpenAMP/open-amp/releases/tag/v2020.01.0 and https://github.com/OpenAMP/libmetal/releases/tag/v2020.01.0 With the transition of the OpenAMP project to a Linaro open source project (https://openampproject.org), we anticipate a return to the normal 6-month release cycle in (approximately) April and October.

Re: [Openamp-rp] Meeting tomorrow 1/30

by Mathieu Poirier

Bill and friends, I would like to talk about the various patchsets floating on the mailing list that I'm keeping an eye on. More specifically where I think the work is at and what the next steps are. I came up with the following list (not in order of priority) along with some comments that we can expand on tomorrow. 1) "V5 remoteproc: updates for omap remoteproc support" [1] Comments: I am waiting on the people at TI that commented on V5 to provide their ACK/comments before doing another review. 2) "remoteproc: Add support for predefined notifyids" [2] Comments: Consensus was to wait for a new resource table definition - anyone working on this? If not I will. 3) "V3 rpmsg: core: add API to get MTU [3] Comments: Bjorn said he wouldn't merge the set without a client. Arnaud pointed to that client [4] in the thread. A new set with both feature (MTU and RPMSG tty driver) needs to be published for 5.6-rc1 and I will review/test it. 4) "V4 remoteproc: add support for co-processor loaded and booted before kernel" [5] Comments: Please send a 5th version when 5.6-rc1 comes out. Tero or Suman will have to ack it before it is eventually merged. On my side I will look at how TI has implemented that feature. 5) "V2 remoteproc: Add elf64 support in elf loader" [6] Comments: Good conversation, please comment or ack next version. 6) "V2 remoteproc: qcom: post mortem debug support" [7] Comments: Good conversation with Bjorn and Arnaud, waiting for Bjorn to release another version. Those take us back to around the September timeframe, which is about the time I started perusing around this project. If there is a set you've been waiting on that dates before September, please send another revision when 5.6-rc1 is released and I will review it. See you all tomorrow, Mathieu [1]. https://patchwork.kernel.org/project/linux-remoteproc/list/?series=229249 [2]. https://patchwork.kernel.org/project/linux-remoteproc/list/?series=228473 [3]. https://patchwork.kernel.org/patch/11333509/ [4]. https://patchwork.kernel.org/cover/11130213/ [5]. https://patchwork.kernel.org/patch/11265869/ [6]. https://patchwork.kernel.org/project/linux-remoteproc/list/?series=182999 [7]. https://patchwork.kernel.org/project/linux-remoteproc/list/?series=221715 On Wed, 29 Jan 2020 at 12:16, Mills, William via Openamp-rp <openamp-rp(a)lists.openampproject.org> wrote: > > Hello all, > > > A reminder that we have normal meeting of openamp-rp sub-project > tomorrow. > > Please think about agenda topics or it will be a short meeting. > > > Thanks, > > Bill > > > --------------------------------------------------- > > William A.

Re: [Openamp-rp] Instructions for Building a Complete OpenAMP Development Environment

Good day Ed, On Fri, 3 Jan 2020 at 17:59, Ed Mooring via Openamp-rp <openamp-rp(a)lists.openampproject.org> wrote: > > On the December 19 call, I committed to sending the instructions I had > provided to the Linaro LITE team to build a bootable image that can be > used to develop and test OpenAMP with Linux on Xilinx QEMU. > > I am using this setup to work with Paul Sokolovsky on getting CI for > OpenAMP on QEMU using LAVA. > > This is a first cut. Feedback is welcome. I finally had time to give this a spin. Just like Bill I hit the "zcu102-zynqmp" problem but fixed it quickly. From there the compilation started and ran for a while until it failed when building QEMU. This is what I got [1] when I launched "bitbake openamp-image-minimal", hopefully one of those SHA will look suspicious to you. I expect a simple misalignment between the various SW repositories fetched by "repo". Speaking of which and echoing Bill's comments, I think an exact git repository and SHA have to be provided for each of the repositories that need to be brought in manually, that is open-amp, libmetal and embeddedsw. At this time I have the following: open-amp: f98eb2a670ce Maintainers: update Ed Mooring mail address libmetal: e3dfc2fe85e5 Maintainers: update project maintainers embeddedsw: e8db5fb11822 Updated the license.txt file Let me know if you find something obvious or if you think one of those projects need to be set to a specific version.

Re: [Openamp-rp] QEMU Docker Container README

by William Mills

Hi Ed, On the 12/19 call you said you had build instructions for the R5 that you had sent to the LITE group. You took an action item to post them here as well. Can you do that please? It would be very helpful. More comments below...
