OpenBSD won't install on an x220 Thinkpad with Coreboot
by Robert Milton 12 Apr '20

12 Apr '20

I'm trying to get OpenBSD to install on an x220 Thinkpad with Coreboot/SeaBIOS but I'm running into two problems: the ethernet device doesn't work and OpenBSD doesn't detect my HDD. dmesg said em0 wouldn't load because the EEPROM had an invalid signature. I have no idea why OpenBSD doesn't see my HDD though. It's strange because everything works fine under Linux. And I cannot seem to mount a usb drive under the OpenBSD installer to attach dmesg errors. I originally posted this as a bug … [View More]

Mainboard porting assistance
by Benjamin Doron 10 Apr '20

10 Apr '20

Hi all, I own an Acer Aspire VN7-572G and have not been impressed with its OEM firmware. After discovering that it does not utilise Intel's Boot Guard technology, that several Skylake and Kabylake laptops (it has a Skylake chip, but I read that the platforms are similar) have received successful coreboot ports and reading the porting guide on the wiki, I figured that I could give porting coreboot to my laptop a shot. When I was done, I figured that I had an image that might boot so I flashed it … [View More]

https://review.coreboot.org/21774 In case anyone else didn't notice - It is a sandy/ivy system with IOMMU. This is great and should help get coreboot in to the corporate user world.

[AMD 16h / ASUS AM1I-A] 1866MHz CL9 RAM runs only as 1333MHz CL9 - how to fix?
by Mike Banon 17 Nov '19

17 Nov '19

A pair of 1866MHz CL9 RAM modules* runs only as 1333MHz CL9 on 16h AM1I-A with coreboot is installed, but worked faster when a proprietary UEFI was installed. To fix this "turtle RAM" coreboot problem I tried to play with buildOpts.c - https://review.coreboot.org/c/coreboot/+/33920 , but the things like "#define BLDCFG_MEMORY_CLOCK_SELECT DDR1866_FREQUENCY" sadly did not help. Any ideas how to improve the RAM speeds? How I can force this RAM to run faster? Best regards, Mike Banon [*] … [View More]

AMD AGESA maintenance and/or deprecation
by Patrick Georgi 16 Oct '19

16 Oct '19

Hi everybody, coreboot is shipping AMD's open sourced AGESA for a few generations as part of its tree. Some people advocate dropping the code due to its quality and lack of maintenance while others are happy with using the code. So: to help keep this code alive, we'd need maintainers - people willing to work through issues, improve the code quality and generally act as a point of contact if any questions arise. One item to start with could be to work through Coverity issues, where the … [View More]

Apollolake: SATA issues
by Christian Gmeiner 08 Oct '19

08 Oct '19

Hi all I have ported coreboot to a custom design based on APL and have random SATA problems with CFast cards. I am using the latest public APL FSP from github with the latest coreboot master. From time to time the SATA link 'dies' during runtime or I it is not possible to establish the SATA link at all (in the used u-boot payload). At the moment I am running out of ideas and I hope someone can point me in the right direction. Btw. with the vendor blob SATA works with out any problems :/ -- … [View More]

KGPE-D16 maintainership
by Piotr Król 02 Oct '19

02 Oct '19

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi all, we see a lot of attention around KGPE-D16 maintainership problems. After discussion with Thierry Laurion (Insurgo) at OSFC2019 3mdeb decided to help in maintaining that platform by organizing crowd founding campaign or getting founds in other ways (direct sponsors). Since we are based in Poland there is chance that even with small contribution from community we would be able to cover the costs. Ideal plan would be to have structure … [View More]

[PATCH] x86_64 support needs testing
by Patrick Rudolph 01 Oct '19

01 Oct '19

Dear coreboot community, Please test and review the patch series [1]. It adds support for x86 long mode on qemu and allows to build test most of coreboot's common code using the x86_64 toolchain. It serves as reference implementation to migrate real hardware to long mode. Here some technical details, that can also be found in the Documentation/ folder: A new tool called pgtblgen create static page tables for a known physical memory address. The page tables are placed in CBFS at the given … [View More]

graphic preallocated memory
by jief 30 Sep '19

30 Sep '19

Hi, I'm new to coreboot and this list, so please forgive and tell me if I'm doing something wrong. I've successfully compile coreboot and flash it to a Lenovo x220. I tried seabios and tianocore as a payload and it works. So strange compile errors as I'm used to when I compile an opensource project. So, _bravo_. What I need now is to be able to set the graphic preallocated memory. Usually in bios, it's "DVMT pre alloc" or something. I know it's possible on this platform because the … [View More]
