Section 3.A.4 of the BY license covers that: "If You Share Adapted Material You produce, the Adapter's License You apply must not prevent recipients of the Adapted Material from complying with this Public License." So distributing a derived work with a different license does not nullify the original terms.

CC BY-SA would not hinder distribution > of documentation. For what it's worth we generally require attribution for public release of both source and documentation. Source can generally be handled in a "weaker" manner via GIT and the copyright lines in the file headers, since the consumers of the source code generally understand how to determine authorship of a file (this is especially useful to determine who is to blame for sloppy coding / outright bugs, and work toward a fix). Plus, there is an intrinsic motivation to keep working on the source code itself; it is inherently rewarding to improve a software project and to be able to make it work better for your specific need. Documentation, on the other hand, is designed for public consumption and is generally a thankless chore for developers who would much rather be adding new features to the software than writing things they already know down. Perhaps the knowledge that someone's name will be attached in perpetuity to the documentation they write might just motivate creation of more material?

I am. With documentation it seems to be the same as with code: The more you blow it up, the more you hide the significant facts. Both should (almost) always be condensed. And most of the documentation in our wiki is outdated anyway. Nico

Having people publish content outside the wiki and link to it from the wiki would obviously lead to even more fragmentation of the documentation than Coreboot already suffers from, making Coreboot remain a project that requires a lot of effort to grok, and has slow uptake. (Cf. Steve Krug's "Don't Make Me Think".) Surely it would be better to aim to make the Coreboot wiki a "one-stop shop" for information about Coreboot, as far as possible. This being so, Coreboot ought to avoid licensing choices that foreseeably fragment the documentation. > In any case, we can (and IMHO should) decouple the discussions about > dealing with current content and about future licensing. Are you really willing to potentially throw away *that* many hundreds of hours of volunteer documentation effort? Regards

coreboot community meeting minutes for March 30th, 2017
by Martin Roth 31 Mar '17

31 Mar '17

Here are the meeting minutes from yesterday's coreboot community meeting. Info about the next meeting (Thursday, April 13) is at the bottom. ####################################################################### Thursday, March 30th, 2017 General coreboot news & discussions * AGESA updates by Kyösti - These need testing, so if you have an AGESA based board, please try them on your board. - https://review.coreboot.org/#/q/status:open+project:coreboot+branch:master+… * TPM regression? - https://ticket.coreboot.org/issues/102 - https://ticket.coreboot.org/issues/104 - PhilippD (TPM area maintainer) is looking into these. * Documentation license - For coreboot proper, coreboot leadership is leaning toward CC-BY, to allow the widest distribution possible. We're not worried about copying things in from other places - those can be referenced on the other websites. - https://creativecommons.org/licenses/ - CC-BY is a non-restrictive license, similar to a BSD license. - CC-BY-SA requires that the license not change, similar to GPL license - Each document is separate, not entangled like the source code, so if we decided to change the license later, we can on an individual basis. Infrastructure Issues & News * Next release 4.6 - Targeting April 17 - Please test your boards - Please fix bugs https://ticket.coreboot.org * Discussions about changing the CCM to a different conferences software. - We can revisit in November if desired. Let's not change before then. * More REACTS systems by Martin (License for 5) - Asus P5GC-MX - Gigabyte GA-G41M-ES2L - Next is AMD Mahogany F10h * Jenkins is misbehaving - completed builds are not marking the servers as being free, causing long delays in running the next build. We're working on it. * Software Freedom Conservancy admission still pending - working out the governance details. - One hangup is the blobs directory. * Working on a jenkins update to show which boards have been changed by a patch. Waiting for jenkins issues to be fixed before moving on with this. * European coreboot conference - https://ecc2017.coreboot.org/ * Denver coreboot conference - Waiting for SFC so we can accept payments * QUESTION: how many folks attend the coreboot conf usually? - Around 50 people max for Denver 2017 unless huge interest. Maybe 100 for the European coreboot conference. Development * flashrom git status? - Do we want to talk about flashrom in the coreboot community meeting - Discuss this with flashrom crew. - Martin isn't positive, but thinks that we're waiting for StefanCT to set up a build test at this point. - Stable branch in gerrit doesn't build (Intentionally) - I think "staging" does, but when a user clones the repo and types "make" in the default "stable" branch it throws an error about needing to use the upstream repo (on flashrom.org) - Can we push to staging now? * Review of siro’s libpayload patches - Patches need reviewers * checkpatch.pl clean-up going on nicely - Lee is done with his cleanup for now - Need to get rid of false positives (Update the script) before turning it on in the builder. ################################################################## Next meeting is Thursday, April 13, 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

Re: [coreboot] Question about Intel HD graphics and FLR

This is indicative of a graphics device without FLR or with a broken reset mechanism. You would have more luck posting on the vfio-users mailing list, the vfio core developer responds to every question there.

I hope and believe that this is our case too. Could you please guide me to transfer the "security register" region from the original flash to new flash using BeeProg? Once again, thanks a lot.

Hi Toan. On BeeProg you can select the offset inside the flash where your image should be loaded to. Just have a look at the lower section in your "load file" dialog box. There is an entry called "Buffer offset for loading". Select positive offset for binary formats and set to 8 MB. That will load your 8 MB image into the upper portion of the buffer and hence your image will be flashed to the upper flash address range. In regard to the Winbond flash we had issues that has shown the same behavior like your case. The root cause in our case was the "security register" called region in the flash which resides above the 16 MB address range and has a size of 0x300 bytes (on W25Q128FV for example). The original flash contents on the CRB contains some data in that region and we were only able to boot the CRB after re-flashing if this region was transferred to the new flash completely. To do so, you must tweak BeeProg a bit, there are special options to erase and program this security registers. If you use a different flash type like N25Q128Ax1E, this issue is not visible because this flash type does not have the security registers the Winbond one has. It seems like CSE checks the used flash type and uses different boot paths inside. I hope that helps. Werner >Dear Goetz, > >Thanks for your reply. I'm trying to rebuild the image. >Another question here: I had an 8 MB Intel-provided image. I'm using BeeProg2C flashing device (with PG4UW software). >Is there any "trick" forcing the flashing device to flash 8 MB image into 16 MB SPI chip? Something likes flash to the low-8MB of chip instead of high-8MB?
