[p8x7x port] Realtek loses its mind & Marvell not going with times.
by Keith Hui 28 Feb '25

28 Feb '25

(Catchy subject eh? There's some truth to both.) My coreboot port to Asus P8Z77-V LE PLUS is almost ready, but I still have two outstanding problems. The board is losing its MAC address, partly because it doesn't have an EEPROM for vital product data. I enabled the rtl8168 driver in coreboot so I can configure the LEDs and MAC address. Lights work great, but the MAC address always revert to 00:00:00:00:00:05 by the time Linux kernel sees it. I would then have to reassign its proper MAC address using "ip link change eno0 address <mac>". I added a debug read back in the rtl81xx driver and the device appears to be taking the MAC I programmed. Board also has a Marvell 88SE9120 for two extra SATA ports. It came up in legacy mode and pata_marvell driver isn't able to operate it. I find no documentation on how to switch to AHCI mode like ASM1061. Needless to say those two ports are currently useless. Ideas? I'm hoping to get this and a few supporting patches in for next release. https://review.coreboot.org/c/coreboot/+/86172 Thanks Keith

Re: PC with coreboot - boot menu locked

This is NOT free hardware, that is, tying people to solutions: "Digital Restricted Management", when people will understand that they will have to start relying on free hardware solutions, as usual, it will always be too late.

Change in coreboot leadership
by David Hendricks 22 Feb '25

22 Feb '25

Hi everyone, After six years on the coreboot leadership team I've decided it's time to pass the torch. I joined the leadership team in 2019 while on a mission to get coreboot back on servers and am pleased with the progress that's been made. Now it's time for me to focus on family and other things and make room for somebody more hands-on with the day-to-day activities of the entire community. I'm happy to announce that Martin Roth will be taking over my spot on the leadership team. Though there are several strong contributors in our community, the leadership team has unanimously selected Martin for this position based on his exceptional qualifications: * Over 26 years of combined firmware development experience, including 13 years in the coreboot community and 13 years of BIOS development prior, mostly at Cyrix/National Semiconductor and AMD. * Significant technical contributions through thousands of patches and thoughtful code reviews, along with mentoring several community members. * Martin has maintained coreboot infrastructure for many years, working behind the scenes to keep the whole project going on a shoestring budget. This included years of maintaining our build infrastructure on servers in his basement. * Extensive experience working with (or at) silicon vendors on the foundational components needed to enable coreboot on bleeding-edge x86 platforms (FSP, AGESA, OpenSIL). * Experience at a variety of companies serving various market segments, ranging from embedded systems at National Semiconductor and Sage, to laptops at AMD and Google, and servers at AMD. * Strong commitment to open-source principles combined with technical expertise to achieve the best possible outcomes in our challenging industry. I'll continue in an advisory role and am also ramping up on some administrative tasks to lighten Martin's load so that he has more time to focus on the codebase. Thanks everyone, and congratulations to Martin!

# 2025-02-19 - coreboot Leadership Meeting ## Attendees Felix Singer, Andre, Martin Roth, David Hendricks, Alicja Michalska, Julius Werner, Werner Zeh, Matt DeVillier, Andy Ebrahiem, Mina Asante, Karthik Ramasubramanian, Jeremy Compostella. ## Open Action Items * 2024-11-27 * [Open] Send out poll with regards to LLM usage (requested by SFC) * 2024-10-30 * [Open] Add clarification to docs, “do not use gerrit change-id or CB: format in reference to already-merged patches”. * 2024-10-16 * [Open] Matt: Set up a meeting to discuss board status alternatives and send out invites. * Decouple data collection with uploading * Require gerrit credentials or other auth to push * Json format? * https://github.com/chrultrabook/linux-tools/blob/main/debugging.sh * 2024-09-18 * [Open] Jon: Schedule a dedicated meeting to discuss the Coverity defects and action plan. * Werner: Send out an invite for the meeting. Sent out a poll to find a time slot: https://rallly.co/invite/1c8J3azXAcje * 2024-05-01 * [Open] Nick Van Der Harst volunteered for Dutch. "gogo gogo" would like to translate to Russian (?) * 2024-01-10 * Nico: (https://review.coreboot.org/q/topic:enforce_region_api) * [Open] Daniel: Look at how we want to localize (non-console) strings for coreboot. Long term project. ## Minutes ### [Werner] Update on Intel’s plans around signing their FSP binaries * Currently not POR for API-mode binary, only for dispatch mode * It should not impact the coreboot flow. However, NDA customers need to keep an eye on it since if it does impact coreboot then that will be a drastic change. * Doc #830299 and #827444 ### [David] Change in coreboot leadership * Martin Roth will take my spot ### [Martin] AMD releasing Phoenix and Turin OpenSIL * Hopefully in February or early March * Somewhat more detail: (https://github.com/openSIL/openSIL/issues/24) * It'll be a while before releasing another one as they switch from proof-of-concept (POC) to plan-of-record (POR), migrating from AGESA to OpenSIL on next-gen SOCs. * Limits of POC * No graphics init, but could use the GOP driver with some effort in creating a wrapper. * Graphics init will be done in GOP driver (UEFI-specific) moving forward * coreboot needs a way to deal with this * We have yabel, x86emu, etc. for legacy graphics init. * uGOP or previous efforts? * AMD doesn't do graphics init before memory is up. * uGOP replaced open-source graphics init, which is the cause of the earlier pushback. * [Alicja] u-boot might have a workable solution? * Need to see what the current status is and potentially borrow parts of it to deal with graphics init. * Linux might be able to init graphics, but AtomBIOS tables still need to be filled in for kernel drivers to read. * [Alicja] On Intel side, there are video BIOS tables as well that fills in things like ports present. Alicja has gotten this working with coreboot + EDK2 by using GOP driver. * [Martin] Another option is to run GOP driver once in the tianocore payload to generate AtomBIOS tables, store the info, and then skip GOP driver on subsequent boots. * It's just a 64KiB chunk of data. * People with AMD NDA support can get a customized AtomBIOS table for their platform. Workarounds to run the GOP driver are more for the community to use. # Next Leadership Meeting * March 5, 2025. * [coreboot Calendar](https://coreboot.org/calendar.html). # Notice Decisions shown here are not necessarily final, and are based on the current information available. If there are questions or comments about decisions made, or additional information to present, please put it on the leadership meeting agenda and show up if possible to discuss it. Of course, items may also be discussed on the mailing list, but as it's difficult to interpret tone over email, controversial topics frequently do not have good progress in those discussions. For particularly difficult issues, it may be best to try to schedule another meeting. # coreboot leadership meeting minutes https://docs.google.com/document/d/1NRXqXcLBp5pFkHiJbrLdv3Spqh1Hu086HYkKrgK…

coreboot on Intel Leafhill (APL)
by Corvin Köhne 17 Feb '25

17 Feb '25

Hi, I'd like to get used to coreboot. Therefore, I'd like to be able to boot Linux and Windows on any platform yet. I've checked the coreboot tree and an Intel Apollo Lake CRB, namely Leafhill, is currently the only platform I have access to and coreboot has a mainboard folder for. So far, I'm able to boot Linux. It has some issues, e.g. the external PCIe slot of the board is not working yet, but it boots. Windows 10 dies with a BSOD and complains about UNSUPPORTED_PROCESSOR. Has anyone seen this issue before or can help me debug this issue? I've attached a boot log when trying to boot a Windows 10 Installer. What I did so far: I'm using a BIOS published by Intel, LEAFHILD.X64.0071.R01.1809030849.bin [1], for IFWI stitching of coreboot. I've verified that the Intel BIOS itself is working on my board. I've extracted the VBT and flashdescriptor of the Intel BIOS and passed it to my coreboot config shown below [2]. I've also applied some patches [3][4] to the coreboot tree itself because the USB port was not working on Linux and the flash layout does not fit to the flashdescriptor extracted by the Intel BIOS.

Coreboot + Tianocore on ThinkPad T480
by Jyber 10 Feb '25

Hi everyone, I’m looking to install Coreboot with Tianocore as UEFI payload on my ThinkPad T480. Is there a detailed guide or installation instructions available? If anyone has experience with this, I’d appreciate any tips! Thanks in advance!
