Coreboot has native x86 code to fully initialize sandy bridge without blobs. Even the VGA bios can be replaced with existing native graphic init (C code for LVDS or libgfxinit for every display output). There is an FSP path for sandy bridge but it is not used much due to native code being easier to work with. > > Thanks <#secure method=pgpmime mode=sign> -- Arthur Heymans

Blobless coreboot on Sandy Bridge and Ivy Bridge?
by Thomasheidler 26 May '17

26 May '17

If one excludes any microcode and the VGA BIOS, is it possible to build a functioning, blobless coreboot for any Sandy Bridge or Ivy Bridge device supported? I'm referring here only to the BIOS region on the flash, not the ME region, IFD and GbE. If the FSP blob is needed, would that be the only blob required? Thanks

In addition to the hang issue the hardware on the test stand seems to be experiencing another fault (not coreboot related); I've disabled the KGPE-D16 tests for now pending diagnostics. - -- Timothy Pearson Raptor Engineering +1 (415) 727-8645 (direct line) +1 (512) 690-0200 (switchboard) https://www.raptorengineering.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJZKHUCAAoJEK+E3vEXDOFbnncIAIhQGJgjeCVoZMrihdmfVaop 53pOEHmLerPKuduqFdooHHkMuE9/fZMraVJVF4m1oOQPI3Dne6UwmcuUrkcZvCoA Oq/pgeU2CeHT8YKVAFSQzc9+Fy4rUxQb05qEy1WboD3Sp49jLAkDDHTQ2S7dTxQs 06eirVIprJ9NpANoo8Ekip8Mggae+GcZjtYZONNZAkGQ//7aT4o+jwsOmcFcy5+7 HCSb0EPIMv7Qq0W9mTWaijDlGqWUCTGRz3qXcaEmqD5TrSJWha6uzq0vK4134CYi lMeFXfJOt3nV+QDlTY/gLqX001aFlbKeGxHiputnIVj2Oz5FWW6I/pq4C6i9h+Q= =GhAR -----END PGP SIGNATURE-----

Documentation on the website
by Patrick Georgi 26 May '17

26 May '17

Hi everybody, to elaborate a bit on what Martin reported from the community meeting: In the last few days I set up our server[0] to regularly render our repositories Documentation/ directory to https://www.coreboot.org/Documentation/, using hugo for formatting and conversion. The old "Documentation" page on the wiki was renamed to Documentation/old. The consequence is that contributions to documentation can be made with the same credentials and using the same review process on gerrit as code contributions. This should alleviate some of the concerns that were recently voiced on this list over the process to obtain wiki accounts. This transition is far from done: Documentation/ itself is a collection of docs of the last 15 years in at least four different formats (TeX, unstructured ASCII text, markdown, PDF), some of it outdated, most of it without declaring a license for distribution (I suppose GPLv2, just like the entire tree, might be applicable, but we should definitely see that we get on top of things here). Documentation/ now explicitly declares CC-BY 4.0 as license for all new contributions as of 2 days ago (there weren't any, so no unexpected surprises here), providing a much clearer situation going forward. The configuration of the site is rather rudimentary: Several documents aren't linked anywhere and the sidebar is somewhat nonsensical, merely mirroring what the old index.html exposed. The design might need improvements. All in all I believe it's a foundation to build upon, though. I'll clean up things over time, but that's not my primary project right now. Feel free to beat me to it :-) Contributions welcome!

It seems like making swag available would be good. Development * AMD SoC development for Stoney Ridge - https://mail.coreboot.org/pipermail/coreboot/2017-May/084291.html * Intel x4x northbridge has a native DDR3 raminit that currently works only on 400MHz Infrastructure news * Gerrit: We plan to update gerrit to version 2.40 on Sunday or Monday. * Jenkins: grumpybuilder is back online. boringbuilder is online but is in testing. * Fossology: https://www.coreboot.org/fossology is now online to analyze coreboot license data. Contact PatrickG or MartinR for a login if you're interested. * Documentation: We've started to get the coreboot/Documentation directory online: https://www.coreboot.org/Documentation/ - Note that this in its infancy, and not all documents are linked from the sidebar yet. Improvements will be coming. Conferences * Denver conference - Starts in just over a week - Working on billing with SFC - we will send out emails in the next couple of days. * European conference - Need to figure out billing details now that coreboot has joined the SFC. - Bochum has flyers - contact Philipp if you want some to distribute. https://twitter.com/_zaolin_/status/867356006552137728 ################################################################## Next meeting is Thursday, June 8, 2017 Check the coreboot calendar for the time in your timezone https://www.coreboot.org/calendar.html Join using the bluejeans web app or the phone bridge: https://bluejeans.com/616384323 Phone bridge call in numbers: https://www.bluejeans.com/numbers Meeting ID: 616384323 Current agenda & history: https://coreboot-meeting.pads.ccc.de/CommunityMeetingTopics

There remains an undiagnosed race condition in coreboot's Opteron startup code that leads to an occasional (empirically this seems to be a 1 in 3 chance) hang in ramstage when the debug level is cranked up and the AP console output is enabled. I've been wondering if I should lower the debug level on the test stand for this particular board to mask the problem, or if these occasional reminders might prod someone to take a look at the problem? - -- Timothy Pearson Raptor Engineering +1 (415) 727-8645 (direct line) +1 (512) 690-0200 (switchboard) https://www.raptorengineering.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJZJxs6AAoJEK+E3vEXDOFbKIsH/iS3yOPdg27VSd1qrcF+ArWf DvqbyRw6/n0uVH74GL+H2hzZljCg8zhgzpBCcF66EqNMdmLri1VSQo3BI6fe7j7K 0ozJ9BbK1UU4yuY40BFOF7zVRE0aPE8HdNoY7tUzFBAA5tslSgfuk158FeejEmXB /qdhBiIjaGoIF8bbOMgg8lI9XUwHxpi2Dvqo7pOH58/bYmavGaKQEgai8ntDtwR7 xFt+kFNqhXvX21990sxOvK44Z0h+P7rPDMjNqniyCQbxR8hGpkflyHjNCBAQ8+i9 7QuMvnPmcaLIjW4FqEmXOFGfI0GAdqzXYARz9/ptmQoOys5u6JAJfz+oDv/4uJw= =00Vf -----END PGP SIGNATURE-----

Re: [coreboot] 2017 North American coreboot Conference
by Martin Roth 26 May '17

26 May '17

Hi Juliana, (and anyone else who has opinions) I'm curious how we should have communicated this better so that we can improve communication for next year, and for the October conference in Germany: https://ecc2017.coreboot.org/ Here's what we've done: 1) We've had a banner across the top of the coreboot homepage for the past month: https://coreboot.org 2) We've had the information set as the topic of the #coreboot IRC channel for most of the past 2 months. 3) We've sent out periodic emails to the coreboot mailing list talking about it. 4) We've announced it on twitter several times. 5) It's mentioned every 2 weeks in the coreboot community meeting, and sent to the mailing list as a part of the minutes. What do you think we should have done to get more attention. Obviously from Naveed's question, other people feel that we haven't been communicating enough either.
