Re: [coreboot] No VGA output on e350m1 after flashing. what to do?

by Reiner Luett

Hi! On 30.06.2013 19:28, Christian Weinz wrote: > Maybe I didn't include the VGA option in the make menuconfig process. > How can I solve this problem? You need to add the VGA Option ROM (VGA BIOS -> Add VGA BIOS image). I've extracted it from the UEFI, but you also could use these: http://www.coreboot.org/index.php?title=ASRock_E350M1&oldid=11114 at the end of the page or you also may be able to use the default AMD fam14 (Persimmon) vbios. You will need to agree to the click through: http://wwwd.amd.com/support/vbioslic.nsf/userverify?openform http://www.coreboot.org/AMD_DB-FT1_PERSIMMON It's a pity, that bios_extract didn't work for now. You could use the AMI Aptio EFI MMTool with wine: http://win-lite.de/benutzer/fernando/BIOS-Tools/AMI_Aptio_EFI_MMTool_v4.50.… You need to extract OntarioEFIVbios with PCI ID 1002,9802 as Option ROM.

Re: [coreboot] KGPE-D16 BMC Port Offer (was: Fund a TALOS Secure Workstation as coreboot build system)

Raptor is chipping in funding for over half of the development work, and Martin is matching pledges, so if there's interest in this port your contributions will go a long way, but it still depends on community interest. Are you willing to contribute to this development project? It is a limited time offer, so the quicker we can reach the relatively low goal to get this work underway the better. :-) Thanks! - -- 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/ iQEcBAEBAgAGBQJYijUnAAoJEK+E3vEXDOFbQKAIAKPqeHZylATs3aZXC2QeTmUG p0bnwfU4G+0qkXEwApoYk+y8WRKEkhBsug5EvzEXw65fAAmwi4COVjUBvm2l9kUI m3/51sfrZRpo+H8c1lXld0WiwomTGapm9FX3rqAjLZn354TOqnrfoGYoJQC+ovKm 0AYXCGN8fmWkr6nTj9Q1tWwxEXrRv48YudF8bDFZhbMjOswnagNzImQNTC6wLgnY +7UyqBgpihc8vh3GoGuPQT1mNpAtUwv1PS8HFGnDO86zW9gWB7+xHEGBhMyy+Rys CTNWkI15X4dy8pz6XIsqjuBNSUcgTnVVAelecdm1BfykpgSyPyOf/39JQc/O41M= =HzeR -----END PGP SIGNATURE-----

CPU Turbo [KGPE-D16]

by Taiidan＠gmx.com

I am wondering as to: * Why 6274 cpu refuses to turbo to the second turbo state with half of the cores in use (it stops around 100mhz before the first turbo state) * Is it possible to force enable second turbo state for all cpu cores, assuming adequate cooling? Or is it controlled on the CPU itself? Off topic but would rather not make another thread: * Does NUMA ram alignment matter performance wise with only one physical CPU? (RAM being split half and half per core set at the moment) * Does anyone know where I could get a reasonably priced 6287SE or 6284SE? or (even better) an engineering model of 62xx?

SPI Flash Writeprotect

by Naveed Ghori

Hi all, Does Coreboot write to the flash chip it resides on? Can this be disabled? Verify of the SPI bios chip fails once the unit has booted up at least once.

Screenshot of payload cbui (coreboot user interface) by siro

by Paul Menzel

Dear coreboot folks, Today I tried cbui [1], the new payload written by siro (Patrick) using the single-header ANSI C GUI library *Nuklear* [2]. With QEMU there are problems when using qemu/q35, but trying it on the Lenovo X60 it worked like a charm (I loaded it from GRUB). Please find a picture attached. In both halves there are some horizontal black lines. But I guess that’s related to the native graphics initialization. So, please test and send commits to siro. Awesome job siro! Thanks, Paul [1] https://github.com/siro20/coreboot/commits/cbui [2] https://github.com/siro20/nuklear

Re: [coreboot] How to reduce formal issues with new contributions from corporations?

I didn’t want to single out anyone as the black sheep. I apologize, if I offended anyone. I totally agree with your view. My focus on corporate developers was motivate by the following two things. 1. Corporate developers certainly contribute most of the commits and code. 2. I believe and assume corporations have *additional* ways to reach “their” developers. > Its our responsibility as reviewers (especially those of us with +2 > rights) to educate them and make sure the rules are followed before a > patch can get submitted. > > That said, I do agree that we have a lot of potential in making this easier > and more consistent for everyone involved.

Most people push the commits from the command line I guess, so that – especially in the beginning – they won’t even access the Web interface? For corporations the following ideas came to my mind. The assumption is that in corporations people are higher to see the colleagues in person or to be in the same building. 1. In each division there is some kind of QA person “holding the hands” for the first commit. 2. Before somebody starts working on coreboot there is a small introduction by a colleague already familiar with the guidelines. 3. Do for example Intel, Google or Siemens have documents (tutorials, videos, presentations) they could share? Would it make sense to create those? […] Regarding improving the documentation, I guess everyone agrees (and nobody wants/likes to do it). In my opinion the easiest way would be to copy as much as possible from other project (like the Linux kernel). Though that should be discussed separately. Thanks, Paul

board status: REACTS uploads incomplete console messages for Asus KGPE-D16

by Paul Menzel

Dear Timothy, dear coreboot folks, Looking through the board status logs, I noticed that at least for the Asus KGPE-D16 the coreboot console message (ramstage) are incomplete [1]. Searching for the string `Show resources in subtree`, shows that it happened between the following two reports uploaded several months ago. ``` 3768284a9 asus/kgpe-d16/4.4-292-g9891b4a/2016-05-20T02_11_58Z # good [2] ac209a115 asus/kgpe-d16/4.4-343-g1716375/2016-05-30T13_15_24Z # bad [3] ``` The lines dropped down from over 3.000 to under 1.000. As some uploads are “missing” in between, I guess some maintenance work was done on the test stand causing the regression. It’s also not a code issue, as Daniel and I get the full logs with no issues [4]. It’d be great if the test stand could be checked, and repaired. Thanks, Paul [1] https://review.coreboot.org/cgit/board-status.git/diff/asus/kgpe-d16/4.5-10… [2] https://review.coreboot.org/cgit/board-status.git/commit/?id=3768284a9 [3] https://review.coreboot.org/cgit/board-status.git/commit/?id=ac209a115 [4] https://review.coreboot.org/cgit/board-status.git/commit/?id=8e7fe74b18ecd9… [5] https://www.raptorengineering.com/coreboot/autotest/logs/1488182375-3-18503…

No external PCIe GPU possible/working on Gigabyte g41m-es2l

by qma ster

Maybe to fix this PCIe GPU issue he just needs to edit a ./coreboot/src/device/Kconfig file? ./coreboot/src/device/Kconfig change config MULTIPLE_VGA_ADAPTERS bool default n to config MULTIPLE_VGA_ADAPTERS bool default y and completely rebuild the coreboot I enabled these options for my G505S laptop with both integrated/discrete graphic, however I am not a gamer so can't notice if there is any positive effect from this option. But maybe this option will significantly improve the thread starter's eGPU experience? What do you think ?
