Hello, is it planned to push drivers from ADI kernel (4.0) to upstream Linux? Or at least update ADI kernel to some longterm release (like 4.4, which has projected EOL on Feb, 2022)? I have noticed that Blackfin processors were in upstream kernel until march this year, so I would like to know if you have some "upstreaming" plans for SC5xx processors.Regards,Jan Havran
we are currently working on an update the the kernel for ADSP-SC5xx which will be based on an more recent upstream version.
By the time we publish we expect this to be the 4.19 LTS release.
Our plan is to release this via Github and to actively work on upstreaming our content and helping to maintain those in upstream from then on.
We are hoping to have more news about this some time early in 2019.
Unfortunately we are not planning on pushing the older 4.0 based kernel changes upstream.
any news on this? According to this post you are preparing Linux-addin 1.4.0 release. I wonder if it will contain some newer version of Linux or just updated 4.0?
Hi Jan,The 1.4.0 release is now a bit behind our current plans. Let me explain what we hope to do during the coming year.
Linux add-in 1.3.1:
Linux add-in 1.4.0:
Instead we will be releasing:
ADI Yocto Linux Release 1.0.0:
We do have a working build of the newer kernel in-house, however this has not undergone release testing.We are planning on making a snapshot of this newer kernel (along with some minor patches to the existing 1.3.0 Buildroot and uBoot) for users that may wish to evaluate the kernel.
thank you very much for this answer. Please allow me to ask one more question: is it still planned to release your Linux kernel on git(hub)?
yes, the kernel will be released via github, along with all the other sources, and our build scripts.
We're hoping to also release a docker image so people can build with exactly the same build environment that is used in production testing.
Is there any chance that we could access snapshot of the newer kernel? We have encountered some issues with the current one, specifically with the hr-timers not working, and would like to see if we have more success with current build.
We have a support case for the aforementioned issue, but yet to hear back. Would appreciate any information and happy to take this offline.
