New extra-selectors mechanism on superiotool
by Maxim Polyakov 26 Jul '24

26 Jul '24

Hello community! I am adding support for f81866 and f81966 fintek chips in superiotool: https://review.coreboot.org/q/topic:%22fintek%22 However, there are some difficulties to make a dump of the registers of these chips. Their global LDN0 and HWM registers contain fields that switch the register banks of these devices. At the same time, these registers contain fields that should not change after they are configured. For example, <Port Select Register - Index 27h> register contains: BANK_PROG_SEL field[3-2] - Bank select for configuration registers (bank 0/1/2/3) and PORT_4E_EN[4] - 0: The configuration register port is 2E/2F. 1: The configuration register port is 4E/4F. I suggest introducing a new element in chip configuration for such registers - an extra selector: https://review.coreboot.org/c/coreboot/+/83196 It seems to me that this is the optimal solution. This allows superiotool to configure the register fields to select a bank before making a correct dump for the corresponding LDN in automatic mode. Please review. Thx // Regards, // Max

# 2024-07-24 - coreboot Leadership Meeting ## Attendees Martin Roth, Felix Singer, Felix Held, David Hendricks, Marshall Dawson, Maximilian Brune, Lean Sheng Tan, Nico Huber, Matt DeVillier, Werner Zeh, Paule Panter, Ron Minnich, Julius Werner, Jason Glenesk, Mina Asante. ## Announcements & Events * FOSSY conference: August 1-4 2024 in Portland, Oregon, USA https://sfconservancy.org/fossy * COSCUP - Taipei, Taiwan on 2024/08/03 ~ 2024/08/04 https://coscup.org/2024/en/landing * OSFC will be in Bochum Germany - September 3-5 https://www.osfc.io * OCP Global Summit: San Jose, California on October 15–17, 2024 https://www.opencompute.org/summit/global-summit ## Open Action Items * 2024-05-01 * Nick Van Der Harst volunteered for Dutch. "gogo gogo" would like to translate to Russian (?) * 2024-03-20 * Martin:To Add a note to the gerrit guidelines to email the leadership for further discussion and guidance when code submissions are not up to standard. * 2024-03-06 * Martin: To update gerrit contributing guidelines documentation. (https://doc.coreboot.org/contributing/index.html) * 2024-01-10 * Nico: [https://review.coreboot.org/q/topic:enforce_region_api] * Daniel: Look at how we want to localize (non console) strings for coreboot. Long term project. ## Minutes ### [Elyes] Submodules * chromeec and opensbi are a pain (#83466 and #83464 ) Not only they have not been updated for more than two years, they can block future improvements (as testing & prepare for C23 see (https://qa.coreboot.org/job/coreboot-toolchain/1646/testReport/junit/(root)… CV_RV64_/) ) * [Martin] I did a little work towards this a while back, looking at fixing chromeec by turning it from a submodule into something more like what we do for payloads. This would let different mainboards specify different versions. Unfortunately, this makes the CI very difficult, as one platform could check out a different version as another platform is building it. I’d suggest we just abandon chromeec from the build completely. Even Google never used it as a part of the coreboot build. * Julius mentioned that there was recently a discussion inside google about using the shared header. * Martin: The chromeEC submodule is huge and in my opinion we should just continue copying the single header file. * Decision: Drop ChromeEC submodule from coreboot. * [Max] regarding OpenSBI: The pain point is mostly src/arch/riscv/opensbi.c since it includes the sbi/fw-dynamic.h from the opensbi repo. I feel the pain since I have had trouble with it in the past too. There are 3 solutions I can think of. 1. We remove it and merge [https://review.coreboot.org/c/coreboot/+/83284] I will try to merge it anyway, since vendors tend to fork OpenSBI rather than upstreaming it. 2. We rewrite src/arch/riscv/opensbi.c to not include the opensbi header. Shouldn’t be too hard to add the structs and types that we need ourselfs. 3. We remove it and implement our own SBI implementation (very unlikely) * Ron (mostly) revived the SBI functionality from 10 years ago. The idea to remove the openSBI header is a good one. * Max - there are only a couple of structures we need. Will prepare a patch this week. ### [Elyes] prepare for experimental and incomplete C23 * If we opt to test and prepare for C23, and if we have to choose one functionality, would it be the use of nullptr constante and nullptr_t type ? (N3042) see [https://review.coreboot.org/c/coreboot/+/83459/8] Is that the right way? * One more question: If you have to choose only one “thing” that would improve the coreboot code (ISO C11 / 17) what would it be? * [Max] As a side note: If we use C23 I would like to make use of some of its features in coreboot code in general. For example using the “#embed” for our unit tests and using a separation to write long memory addresses (e.g. write 0xFFFF_FFFF instead of 0xFFFFFFFF) * Julius: I’d advocate we don’t do this - this is something brought in from c++ to address things that aren’t generally applicable to coreboot. It’d be very intrusive. * Ron: Unless there’s some benefit that we don’t currently see, what’s the point? * Julius: There’s no objection to using C23 in general, but the nullptr_t type doesn’t gain us anything. Max++ * Decision: Not looking to pursue this currently. ### [Sheng] RFC for UPL support patch by Max *[https://review.coreboot.org/c/coreboot/+/76591] * Please review. * Matt: Some of the names could be improved. * Martin: Let’s put this discussion off until next week - I’ll make sure that it’s in the list of patches to review. * UPL Spec is in github - please contribute. * [https://universalpayload.github.io/spec] * U-boot support: [https://patchwork.ozlabs.org/project/uboot/list/?series=416058] * Edk2 as well. Linuxboot will follow after ### [Nico] Flashprog releases and HW support * Flashprog does regular releases now. Is it ok to announce them on the coreboot ML (about every 3~4 months)? Just checking if anybody has feelings against it… * Probably a little more delicate: What to do about stale "Flashrom support" lines in docs and board_info.txt where it's known broken? remove? replace w/ Flashprog? do nothing? * Martin: Let’s add a line for flashprog support. If flashrom is broken on a platform mark it as no. * David: Do we want to create a CSV list for flash programs instead of separated lines? * Martin: this seems reasonable to me. * Nico: We’d need to update the various scripts to generate the website and lint the file. Nico can take a look at this. * Matt: Sure, we can even add non-open firmware flash packages. # Next Leadership Meeting * August 7,2024. * [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 [2024-07-24](https://docs.google.com/document/d/1NRXqXcLBp5pFkHiJbrLdv3Spqh1…

[coreboot - Bug #548] (New) Computer Fails To Recognize Upgraded WiFi Card
by Jeremy Brown 17 Jul '24

17 Jul '24

Issue #548 has been reported by Jeremy Brown. ---------------------------------------- Bug #548: Computer Fails To Recognize Upgraded WiFi Card https://ticket.coreboot.org/issues/548 * Author: Jeremy Brown * Status: New * Priority: Normal * Target version: none * Start date: 2024-07-15 ---------------------------------------- I am running coreboot 24.05 on my Lenovo X201. I decided to upgrade my WiFi card from an Intel Centrino Advanced-N 6205 to an Intel Wireless-AC 7260; since I selected the option to support Intel PCIe cards in my build config I expected everything to work but my computer fails to recognize the new card. The old card is still recognized if I reinstall it so I know I didn't mess up the socket somehow; I've read reports of the 7260 [working with a modded factory BIOS](https://richbits.rbarnes.org/installing-the-intel-7260-in-the-thinkpa… so I don't think there's an electrical issue. I've attached lspci data from both chips, lmk if additional information is needed. ---Files-------------------------------- 6205_lspci_tree.txt (1.63 KB) 7260_lspci_tree.txt (1.57 KB) 6205_lspci.txt (12.8 KB) 7260_lspci.txt (12.2 KB) -- You have received this notification because you have either subscribed to it, or are involved in it.

[ANNOUNCE] Go utility *hda-decoder*
by Paul Menzel 16 Jul '24

16 Jul '24

Dear coreboot and Linux folks, The utility *hda-decoder* written by Nicholas Sudsgaard was just submitted to the coreboot repository [1][2]. > util: Add hda-decoder > > This tool helps take off the burden of manually decoding default > configuration registers. Using decoded values can make code more > self-documenting compared to shrouding it with magic numbers. > > This is also written as a module which allows easy integration with > other tools written in Go (e.g. autoport). Kind regards, Paul [1]: https://review.coreboot.org/c/coreboot/+/80470 [2]: https://review.coreboot.org/plugins/gitiles/coreboot/+/b205f4e53ec30487ea1c…

Announcement: Official V0.9.1 Release for Universal Payload Sepcification
by Lean Sheng Tan 13 Jul '24

13 Jul '24

Hi everyone, After 2 years of endless discussions and relentless effort, we officially landed the V0.9 (and V0.9.1) of *Universal Payload Specification (UPL)* yesterday!!! V0.9 formally introduces using Device Trees as the standardized Payload Handoff Format to pass data from Platform Init (e.g. coreboot) to Payload (e.g. UEFI payload or LinuxBoot). This reduces the data handoff friction and proprietary handoff formats currently exist in each and every firmware project (e.g. HOB, coreboot table). A brief historical background: Universal Payload started as a sub-project under Intel's Universal Scalable Firmware Initiative. Since its introduction, Intel has been actively seeking for the firmware community's input to help make it a reality, to help standardise a common architecture and interfaces between Platform Init and Payload. Later on, 9elements actively collaborated with Intel to work with all major firmware projects (coreboot, U-Boot, edk2, Linuxboot) with the support of all architecture (x86, Arm, RISC-V). We have been actively promoting and collecting feedback in every means we could (mailing lists, OSFC, OCP Global Summit, COSCUP). I could not find words to summarize the 2 years tireless efforts made by all the UPL contributors: with about *2-4 meetings per month since May 2022*; countless back and forth discussion and some compromises made in between to find common ground that fits all Firmware solutions and projects; some technical setbacks with failed POCs and then persistent testings on coding sites; new expectations and issues pop up now and there that setback the initial timeline again and again... I owe all of them my greatest gratitude for their hard work. I would like to specially thanks *Vincent Zimmer* from Intel for making this happen in the first place - early commitment from *ARM*, Intel/ edk2 / Slimbootloaders maintainers, *Chasel Chiu* and *Dong Guo*, *Maximilian Brune* and *Arther Heymans* from coreboot, *Dhaval Sharma* and *Aaron Durbin* from Rivos, and *Simon Glass* & *Ron Minnich* who are both great visionaries in the Open Firmware world. In short, this is truly the first ever community effort that brings all firmware communities to collaborate together, in the very common goal to make Open Source Firmware a better place for everyone. For sure, this cannot and never will please everyone, and like all things there are always many issues in the first revision. Hence, I sincerely pledge to all of you, to help and contribute to this spec. This is an open invitation, as we follow the ethos of "*For Community, By Community*", the first open source spec that is owned by all the open firmware communities. Please refer here for the latest spec: *universalpayload.github.io/spec <http://universalpayload.github.io/spec>* Feel free to contribute here: *https://github.com/UniversalPayload/spec <https://github.com/UniversalPayload/spec>* WIP coreboot patch: *https://review.coreboot.org/c/coreboot/+/76591 <https://review.coreboot.org/c/coreboot/+/76591>* Last but not least, I also wanted to specially thank 9elements Cyber Security for all the support since the very beginning that helps me to navigate through all the hurdles and issues for the past 2 years. Let's continue to work together for a better Open Source Firmware for everyone. Thanks, Sheng

Announcement: Introducing UEFI Capsule Update Integration for coreboot with EDK II
by Beata Skierka 11 Jul '24

11 Jul '24

Hello, We are pleased to announce the launch of a project by 3mdeb aimed at integrating UEFI Capsule Update for coreboot with EDK II as a payload. This initiative aims to bring the capsule-based update method, providing an alternative to the traditional flashrom-based method, which becomes more and more difficult to implement, due to the restricted OS-level access to the firmware storage. One of the main goals is also to ease the integration and firmware update deployments via the fwupd for devices running open-source firmware (based on coreboot + EDK II). For a detailed project outline, please visit our Dasharo documentation [1]. We are looking for feedback through comments on this thread or via the built-in discussion module on the website. Although the project plan has been already accepted by the NLnet Foundation, there may be still some room for justified changes. You can track project's progress via the GitHub Project [2]. Your feedback and participation would be much appreciated. We welcome your involvement in discussions, reviewing, and testing. You might already have seen some first patches as a results of this project getting started, such us: - https://review.coreboot.org/c/coreboot/+/82247 - https://review.coreboot.org/c/coreboot/+/82248 - https://review.coreboot.org/c/coreboot/+/82249 - https://review.coreboot.org/c/coreboot/+/82610 We acknowledge and appreciate the funding support from the NLnet Foundation.

VxWorks 7 rebooting with UEFI payload
by Moorthi M.s 11 Jul '24

11 Jul '24

Hi, I am developing coreboot along with UEFI payload for a custom board derived from CFL H RVP11 CRB. Modifications are done as per the custom board and board was booted to CentOS and Windows. When we try to boot VxWorks 7 with native UEFI loader, the board was rebooting. But the same UEFI loader and VxWorks image is booting with BIOS version of the same custom board. Is there any modification need to be done to boot VxWorks 7? Thanks & best regards, Moorthi S
