Agenda for OpenAMP TSC call on October 9th

by Nathalie Chan King Choy

Hi all, Here is the proposed agenda: * What are the working groups' goals for the next 6 months? * Does the TSC have feedback on those goals? * Do those goals require any budget $? (e.g. tools licenses) * Governance: Stefano to present how Xen Project makes decisions and resolves conflicts * Governance: Discuss the next open item(s) on https://github.com/OpenAMP/website/blob/master/_pages/governance.md Also, I have posted some news to the project website: https://www.openampproject.org/news/ You can find the links to the ELCNA20 OpenAMP presentation recording, the OpenAMP white paper, and the MGC Electronic Design Magazine article in the posts.

Scheduling next TSC call: Sept -> Oct?

by Nathalie Chan King Choy

Hi OpenAMP TSC, At our last TSC call in July, we had talked about having the next call in September, before Linaro Virtual Connect, so that we could discuss the OpenAMP Project Update slides for the Linaro Virtual Connect session. However, it turns out that the slides deadline is Sept 16th and in the week of Sept 7th we have calls scheduled for OpenAMP App-services, OpenAMP Board, and (typically*) OpenAMP remote-proc, so having an OpenAMP TSC call seems a bit much, given the overlap in attendance among the calls. (*I believe Bill M. will be sending a new meeting series.) Would anyone be opposed to having the next TSC call in October, to spread things out a bit? We can discuss interesting things that came out of Linaro Virtual Connect sessions. Thanks & regards, Nathalie P.S. If anyone had their heart set on participating in the slides review for the OpenAMP Project Update, email me directly & I'll include you when we review over email.

update of the cmake minimum version for openamp and libmetal libraries

by Arnaud POULIQUEN

Dear TSC members, Ed and I are having a discussion about the minimal version of cmake that we should support for the openamp and libmetal libraries. Today, the minimum supported version (checked during cmake runtime) is cmake v2.6. This constraint on the minimum supported version was specified when the libraries were created and has never been updated. In our environment we test the libraries with cmake V3.x, so cmake v2.6 support is no longer guaranteed. Our proposal is to update the minimum version to 3.5 which corresponds to a version that we can simply test as part of the Ubuntu Xenial (16.04 LTS) distribution. This could be effective for next October release. As this update may be part of the stability policy, we would like to be sure that there are no objections from members before proposing a pull request.. So, If you have any objections or concerns about this update, please let us know. Thanks and Regards, Arnaud

Re: [OA-Tsc] API and Wire protocol stability

Hi Bill, On 5/20/20 6:04 AM, Mills, William via Tsc wrote: > Arnaud, > > Thanks for the review. > > WRT to memory footprint and no dynamic memory allocation > > I wonder if these are better handled with test cases? > Or are you worried that it is too easy to change the test case? Yes testing is a good solution to verify the requirements. However, my concern here is more that these legacy requirements are not specified in OpenAMP project. Personally, i am still applying a default policy on them even if there are not specified. But like the API, does this makes sense for every members? That's why I would suggest that these requirements be re-validated by the TSC members and that we find a way (policy, guideline, other...) to clarify them in the documentation.

Re: [OA-Tsc] API and Wire protocol stability

by Mills, William

Arnaud, Thanks for the review. WRT to memory footprint and no dynamic memory allocation I wonder if these are better handled with test cases? Or are you worried that it is too easy to change the test case? Thanks, Bill -----Original Message----- From: Tsc [mailto:tsc-bounces@lists.openampproject.org] On Behalf Of Nathalie Chan King Choy via Tsc Sent: Tuesday, May 19, 2020 12:23 PM To: tsc(a)lists.openampproject.org Subject: [OA-Tsc] FW: API and Wire protocol stability Message went to tsc-bounces instead of tsc list. -----Original Message----- From: Arnaud POULIQUEN <arnaud.pouliquen(a)st.com> Sent: Tuesday, May 19, 2020 8:50 AM To: Mills, William <wmills(a)ti.com> Cc: tsc-bounces(a)lists.openampproject.org Subject: RE: API and Wire protocol stability Hi Bill, all Thanks Bill for this proposal. Look to me a good approach. Could version number management in openAMP help applications to better manage API and Wire protocol evolution? Today the status is: - libmetal: API fo get lib version exists ( MAJOR.MINOR.PATCH format) but no evolution of the version since a while: Current version 0.1.0 - OpenAMP: version only handled for Zephyr with same format than libmetal, no API to get the library version. Current version 0.1.0 Another point, probably quite out of scope here, but reviewing this policy reminds me some of the requirements that were defined when we started the OpenAMP library redesign in 2018. - The first was the library's memory footprint. This requirement was a condition for the viability of OpenAMP on MCU with low memory. The target was 3 kB for the ROM. Today, we are close to ( but higher than) this target. And the footprint continue to grow by adding fixes and new features. For instance, the cost of integrating the "zero copy" feature is about 0.5 KB. - The second was the support of systems without dynamic allocation. Today, I think we are still meeting this requirement. I wonder whether these requirements should not be reshaped in policies, as they also have an impact on the evolution of the library. So I would appreciate if we can also clarify this 2 points, (after the API and wire protocol policies, of course :) ) Thanks Arnaud > -----Original Message----- > From: Tsc <tsc-bounces(a)lists.openampproject.org> On Behalf Of Mills, > William via Tsc > Sent: samedi 18 avril 2020 17:41 > To: tsc(a)lists.openampproject.org > Subject: [OA-Tsc] API and Wire protocol stability > > All, > > I have the action to write up thought on API stability. > On 4/17 we added wire protocol stability to the list. > There is also discussion of API homogeneity across different > implementations and/or operating environments but that topic is out of > scope for this discussion and I specifically opted out of leading that > discussion. > > **** API Stability: > > For reference here is the Zephyr policy on API lifecycle: > https://docs.zephyrproject.org/latest/development_process/api_lifecycle.h > tml > > ** Scope: > > The scope of the OpenAMP API lifecycle policy is mostly the libraries and > supporting code owned by the project. > Today that is primarily the open-amp and libmetal libraries but we expect > that to expand in the future. > > Specifically out of scope would be the APIs internal to the Linux kernel.
