OpenBSD won't install on an x220 Thinkpad with Coreboot

by Robert Milton

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 report to bug report mailing list but Theo said it would be better suited for Coreboot's and wasn't a bug in OpenBSD.

Optiplex 790 now has preliminary support by coreboot

by Taiidan＠gmx.com

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.

Coreboot doesn't POST on ASUS KCMA-D8

by espionage724＠posteo.net

I have a KCMA-D8 motherboard with two Opteron 4226s, and 6x4GB (24GB) Hynix HMT151R7BFR4C-H9 RAM sticks. All my attempts of getting Coreboot to POST with this board so far haven't worked. I'm compiling Coreboot from Git (master branch), and can build it without issue. A pre-built Libreboot ROM (20160907) POSTs and boots fine. For Coreboot's config, I've tried including/excluding CPU microcode updates, along with some less important-sounding options. For hardware, I've tried unplugging everything external (KB/mouse), my GPU (RX 580), and only had a single RAM stick in (slot A1). I've also tried a single CPU being powered (kept the 2nd CPU in but only had a single 4-pin CPU going to the 1st CPU). Can anyone else confirm Git builds of Coreboot booting on this board, or provide any tips as to anything I could be missing? I see this issue https://ticket.coreboot.org/issues/151 but there's a board status months after that that looks like it boots: https://review.coreboot.org/cgit/board-status.git/tree/asus/kcma-d8/4.7-789…

Menu time-out missing when GRUB is loaded quickly and `at_keyboard`

by Paul Menzel

Dear GRUB folks, When the module `at_keyboard` is directly into the GRUB image (`--modules`), and GRUB is loaded really quickly, then the timer, which, after counting down to 0 (`GRUB_TIMEOUT`), starts the selected entry, is not shown. I noticed this issue on the ASRock E350M1 with coreboot and a small GRUB payload, and a PS/2 keyboard connected. Due to the missing time-out, I manually have to confirm the selected entry. By chance, the keyboard wasn’t connected setting up the system somewhere else, and that made it work as expected. So, it looks like, it’s related to `at_keyboard`, and some race, because the bigger default GRUB payload also does not show the problem. Luckily, it’s easily reproducible with GRUB’s standard `default_payload.elf` and QEMU. Please find the instructions below to reproduce the issue. $ git clone https://review.coreboot.org/coreboot $ cd coreboot $ # save attached grub.cfg in the directory $ util/scripts/config -e PAYLOAD_GRUB2 grep: .config: Datei oder Verzeichnis nicht gefunden $ util/scripts/config -e GRUB2_INCLUDE_RUNTIME_CONFIG_FILE $ util/scripts/config -e GRUB2_MASTER $ util/scripts/config -e CONFIG_COREBOOT_ROMSIZE_KB_2048 # default of 512 KB too small for GRUB payload $ util/scripts/config -e ANY_TOOLCHAIN $ # or: make crossgcc-i386 CPUS=`nproc` $ make olddefconfig $ make -j`nproc` $ qemu-system-x86_64 --version QEMU emulator version 3.1.0 (Debian 1:3.1+dfsg-2+b1) Copyright (c) 2003-2018 Fabrice Bellard and the QEMU Project developers $ qemu-system-x86_64 -M pc -bios build/coreboot.rom -serial stdio *No* time-out is shown. Telling QEMU to emulate a USB keyboard, indirectly disabling the PS/2 keyboard, the time-out *is* shown. $ qemu-system-x86_64 -M pc -bios build/coreboot.rom -serial stdio \ -usb -device usb-kbd Not including `at_keyboard` directly in GRUB’s “core image”, modules loaded automatically, the time-out is also shown. `set debug=at_keyb` did not show anything interesting. Can you reproduce that, and see what the problem is? Kind regards, Paul PS: Please find the instructions to build GRUB as a coreboot payload done by coreboot’s Kconfig system automatically, and how put it into the coreboot filesystem CBFS. ``` $ git clone https://git.savannah.gnu.org/git/grub.git/ $ cd grub $ git describe --tags --dirty grub-2.02-238-ga791dc0e3 $ ./autogen.sh $ ./configure --with-platform=coreboot $ make default_payload.elf # this includes `at_keyboard` $ cp default_payload.elf my/coreboot/folder/ $ cd my/coreboot/folder/ $ build/cbfstool build/coreboot.rom print $ build/cbfstool build/coreboot.rom remove -n fallback/payload $ build/cbfstool build/coreboot.rom add-payload -f payload.elf -n fallback/payload -c lzma ``` Kind regards, Paul

Braswell FPS memory init problems

by Michal Zygowski

Dear coreboot community, I am experiencing problems with FSP Memory Init on Braswell SoCs. FSP Memory Init is not returning. I have following processors that fail: Celeron J3060 and Celeron J3160; both have the same issue. The platform has 1 SODIMM module on channel 0. I am feeding the UPD header with correct SPD, but still no luck. I have also tried FSP MR1 and MR2, but nothing works. Is anyone here more experienced with Braswell platforms? Could You give me some advices? Best regards, -- Michał Żygowski Embedded Systems Engineer http://3mdeb.com | @3mdeb_com

Re: [coreboot] [LinuxBoot] FOSDEM 2019 deadline today

by Carl-Daniel Hailfinger

In that case, I'd also like to point you to the deadline for submitting main track talks which is tomorrow(!). https://fosdem.org/2019/news/2018-08-10-call-for-participation/ Having a coreboot/LinuxBoot talk there would be awesome. Ron/David, could you submit something or do you have someone in mind who can do that? There's also lightning talks, deadline is a bit later. OK, I'm submitting a request for a stand. I need a backup contact for the stand. Who is willing to do that? AFAICS we can still change the backup contact later if life happens.

RTC issue

by Hilbert Tu(杜睿哲_Pegatron)

Hi, My platform is Intel Denverton with Coreboot 4.8.1 and it can boot up successfully except RTC. There is always an error like “unable to open rtc device (rtc0)” when I try to set clock. But if I use BIOS to boot up again, this error will be disappeared and later boot up with Coreboot and setup hwclock successfully. Does anyone have same experience and know how to fix it?

Second call for mentor candidates and project ideas for Google Summer of Code 2019

by Patrick Georgi

Hi everybody, I just want to remind you that we're applying for GSoC this year and for planning reasons they want us to state how many mentors we expect to have. So if you're interested to potentially help a student get up to speed on a firmware related topic (coreboot or nearby projects), please reach out to me until Sunday, so I can finalize the paper work (which is due next week). While students shall outline the project they want to work on in their application to GSoC, it's normal and expected to provide guidance in the form of project proposals. If you have ideas (and ideally are prepared to mentor students working on them) please reach out to me as well. I'll incorporate them in https://review.coreboot.org/c/coreboot/+/30972 so we'll have a maintained collection on our documentation site. That list is also suitable for other situations but whatever the occasion, it always help to have a point of contact listed with any idea so that somebody interested in working on them knows who to contact for details and help. Thanks, Patrick -- Google Germany GmbH, ABC-Str. 19, 20354 Hamburg Registergericht und -nummer: Hamburg, HRB 86891, Sitz der Gesellschaft: Hamburg Geschäftsführer: Paul Manicle, Halimah DeLaine Prado

Re: [coreboot] Upgrade the 12 years old LZMA libraries - should we do it?

by Carl-Daniel Hailfinger

Hi Ivan, On 03.04.2018 20:03, Ivan Ivanov wrote: > I have noticed that both coreboot and seabios are using the very old > versions of LZMA SDK. True.

Do you have any numbers for this? An improved compression ratio and improved speed would be nice indeed, but how does the size of the decompression code change? If the decompression code grows more than the size reduction from better compression, it would be a net loss. A significantly reduced decompression speed would also be a problem. Decompression speed would have to be measured both for stream decompression (i.e. the decompressor gets the compressed data in single-byte or multibyte chunks) as well as full-size decompression (i.e. the decompressor can access all compressed data at once). We also have to make sure that stream decompression still works after the change. > Do you think it should be done, or you are OK with using such an > outdated version? A size benefit for the resulting image is a good reason to switch. Regards, Carl-Daniel
