Open letter to Intel regarding the PSE on Elkhart Lake
Dear coreboot community. I guess the most of you have seen the tension that was introduced to the community once Intel started to enable the Programmable Service Engine on the new IOTG SoC called Elkhart Lake (for reference, please see [1]). One of the outcome of this difficulties was to ask Intel for open sourcing the PSE code in order to avoid a new blob being introduced to coreboot. I took this action item and reached out to Intel in this regard. As a result I have had two meetings with the responsible people at Intel and they started to look into this request. So as of now Intel is analyzing the code to understand what needs to be done to open source it. What has been mentioned by Intel to me is that up to now nobody else have ever requested this for the PSE. Furthermore Intel let me know that it would be easier to convince the management layer to spend work on open sourcing the code if there would be more people from different companies requesting the same. My first guess was: we can do this! Therefore I have drafted up an open letter which I would like share with all of you: https://openletter.earth/request-for-opening-the-source-code-for-the-pse-on- elkhart-lake-26bad82a The wording have now been reviewed for two days between different parties and I would like to keep it as it is in order to get it done in time. This is now the moment where you can raise your voice! Please have a look at the open letter and sign it if you agree with the terms and if you support this approach. The more people we get the higher are our chances to be visible as an open source community. And it would be really helpful if we could get this letter signed by companies, this will for sure increase the traction of this request. I will keep this letter in "signing" state until 2021-12-09 07:00 am German time. Once we are there I will hand it over to Intel. Thank you for your support in advance Werner [1] <https://review.coreboot.org/c/coreboot/+/55367> https://review.coreboot.org/c/coreboot/+/55367
Kudos on taking the initiative (and making some progress -- at least getting an audience!)! On Friday, December 03, 2021 10:01:49 AM Zeh, Werner wrote:

Hi everybody. It has been a while now that we started the open letter to Intel regarding open-sourcing the PSE firmware. I am now happy to announce that all this effort was not worthless! Intel pushed the PSE firmware sources yesterday to github [1]! A big "Thank You!" to all the supporters of the initiative out there. Werner [1]: https://github.com/intel/pse-fw
Nice job Werner, I'm completely shocked! On Thu, Apr 21, 2022, 10:24 PM Zeh, Werner <werner.zeh@siemens.com> wrote:

Yes, nice job Werner! Since you’ve been working on Elkhart Lake, can I inquire if you have booted it to an OS via eMMC and/or iPXE using coreboot? If so, with which payload?

Hi Jay. We do use a self written payload based on a Linux kernel with a userland application which simply do a kexec to the next kernel. With this payload we do boot into a Linux on an eMMC on one of our Elkhart Lake designs. With iPXE I do not have any experience on Elkhart Lake. Werner

Dear coreboot community. As I have written here Intel took care of our feedback and open sourced the PSE code at github. I have set up a "Thank you, Intel!" open letter [1]. Please do sign it as well to express that we honor the efforts Intel took into this based on our feedback. Thank you all for supporting this.
