[coreboot - Bug #536] (New) Cannot build coreboot-sdk

Issue #536 has been reported by Michał Żygowski. ---------------------------------------- Bug #536: Cannot build coreboot-sdk https://ticket.coreboot.org/issues/536 * Author: Michał Żygowski * Status: New * Priority: Normal * Assignee: Martin Roth * Target version: none * Start date: 2024-04-24 ---------------------------------------- I have just tried building coreboot-sdk from scratch and could not get past the step of installing the required packages. Found out that diffutils dependency on libcurl4t64 break libcurl4 (change apt-get to apt to see verbose information message like below): ``` shell > [coreboot-sdk 2/4] RUN useradd -p locked -m coreboot && apt-get -qq update && apt -qqy install --no-install-recommends bash-completion bc bison bsdextrautils bzip2 ca-certificates ccache cmake cscope curl device-tree-compiler dh-autoreconf diffutils exuberant-ctags flex g++ gawk gcc git gnat-13 golang graphicsmagick-imagemagick-compat graphviz lcov less libcapture-tiny-perl libcrypto++-dev libcurl4 libcurl4-openssl-dev libdatetime-perl libelf-dev libfreetype-dev libftdi1-dev libglib2.0-dev libgmp-dev libgpiod-dev libjaylink-dev liblzma-dev libnss3-dev libncurses-dev libpci-dev libreadline-dev libssl-dev libtimedate-perl libusb-1.0-0-dev libxml2-dev libyaml-dev m4 make meson msitools neovim ninja-build openssh-client openssl parted patch pbzip2 pkg-config python3 python-is-python3 qemu-system-arm qemu-system-misc qemu-system-ppc qemu-system-x86 rsync sharutils shellcheck unifont unzip uuid-dev vim-common wget xz-utils zlib1g-dev && apt-get clean: 2.106 2.106 WARNING: apt does not have a stable CLI interface.

[coreboot - Feature #420] (New) Use standard format of TPM event log
by Krystian Hebel 07 Aug '24

07 Aug '24

Issue #420 has been reported by Krystian Hebel. ---------------------------------------- Feature #420: Use standard format of TPM event log https://ticket.coreboot.org/issues/420 * Author: Krystian Hebel * Status: New * Priority: Normal * Target version: none * Start date: 2022-10-12 * Related links: [1] https://trustedcomputinggroup.org/wp-content/uploads/TCG_PCClientImplementa… [2] https://trustedcomputinggroup.org/wp-content/uploads/TCG_PCClient_PFP_r1p05… ---------------------------------------- Currently coreboot uses proprietary format for TPM event log. TCG has standardized log formats, differently for TPM1.2 (aka legacy or SHA1) [1] and TPM2.0 (aka crypto agile) [2], both of which can be parsed by Linux kernel and exposed in sysfs. I don't know of any tool outside of cbmem which can parse coreboot format; this includes payloads which may be interested in continuing chain of trust started by coreboot. Another incompatibility is caused by vboot's assignment of PCRs. Roles of PCRs are roughly specified by TCG in both of mentioned documents, they are more or less compatible with each other, but not with current coreboot code. These changes could break assumptions made by existing platforms, so they should be made as Kconfig options. This is a tracking issue to collect subtasks that need to be done in order to support standard event log formats. -- You have received this notification because you have either subscribed to it, or are involved in it.

# 2024-06-26 - coreboot Leadership Meeting ## Attendees Felix Singer, Felix Held, Werner Zeh, Jonathan Hall, David Hendricks, Jay Talbott, Mina Asante, Martin Roth, Karthik Ramasubramanian, Marshall Dawson, Shelley Chen, Maximilian Brune, Lean Sheng Tan. ## 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 ## Improving coreboot processes ### [Martin] bi-weekly review meetings * In an attempt to get patches merged more quickly, we’re looking at adding a meeting to review patches and try to get blocking issues sorted out. This will start as a bi-weekly meeting of 1 hour and we’ll see where things progress from there. Any preference for Tues/Wed/Thurs? 16:00, 17:00, or 18:00 UTC? (should we define it in UTC or in some other time zone that may switch based on daylight savings?) * 17:00 UTC on Wednesdays opposite the leadership meeting. * David: Start a new google doc to ask for reviews. * Werner: Dedicated email address * Felix: Would it be better to just generate a list? * David: Let’s do both requests and generate a list of patches to review. * Karthik: Should maintainers be involved? * Martin: Absolutely, if they come to the meeting. * David: The idea is to remove bureaucracy * Werner: Who should we invite? * Martin: core devs * Felix: We can change things that don’t work well. ### [Martin] Merge SLOs * Can we define objectives for timeframes to get patches merged to different areas in the codebase? An individual mainboard that doesn’t affect the rest of the codebase doesn’t need as much scrutiny as core code that affects every platform. * Mainboard: 1 week? * FelixH: So what do we do if we get past this timeframe? Just merging anything because it’s passed the SLO period seems like a bad idea. * David: This is designed to help people who are new to the project. We don’t just want to merge stuff, but for isolated code, maybe we can look the other way at imperfections. * FelixH: Frequently add comments and mark as resolved. * David: SoC code still needs to be held to higher standards. * David: We still expect authors to be responsive to feedback. * FelixH: We still need reasonable patches as well - one logical change per patch. * Martin: Do we want any areas besides Mainboards? What about SIOs? * Werner: Maybe drivers? * Max: Everything other than mainboards can be used by multiple vendors? * Martin: It doesn’t seem unreasonable to try to get things merged in a month. * FelixH: It would be good to have a list of things to look at. * Martin: Send out an email with a list of patches which will be looked at in the next meeting? (Yes) * Add a month SLO for drivers & SIOs initially. ### [Karthik] RFC - Extend Coreboot FileSystem to disk * [Extend CBFS to Storage Media](https://docs.google.com/document/d/1LFXIr38_u2bnXY9G6-uJHYxIAFqwX9tU… * Werner: How do we make sure we don’t address the wrong drive? * Karthik: Define a rule in FMAP to describe the characteristic of the disk. * Werner: Wouldn’t coreboot need to search all of the disks? Finding it would be tricky. * Werner: Don’t like searching multiple partitions. * Martin: So would this just be in libpayload * Karthik: The initial code would be just for libpayload. * Martin: I can’t really think of any uses for this in coreboot other than a splash-screen, so I’d really prefer that it just stayed a part of libpayload. * Karthik: We can keep this just a part of libpayload. If we ever need to change that, we can address that again at that point. A notice will be added. * Werner: Last time I dealt with EMMC, there was a difference in speed - training slowed things down and it needed write support. * Martin: I feel like there’s a big difference between training and any writes needed for that, and actually accessing data on the drive. I’m not opposed to the idea of starting training earlier. * David: Are there any patches? * Karthik: I can upload patches in the next week or so - it’ll be a WIP patch. ### [Martin]: Setting aside the reformatting project with clang-format until it’s more stable and has fewer quirks. # Next Leadership Meeting * July 10,2024. * [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 *[2024-06-26](https://docs.google.com/document/d/1NRXqXcLBp5pFkHiJbrLdv3Spqh1Hu086HYkKrgKjeDQ/edit?p).

Updating the submodule pointer of 3rdparty/fsp brings in commit 849ce8261bb0 (Tiger Lake FSP A.0.7E.70) with no commit message body. The diff contains: TigerLakeFspBinPkg/Client/SampleCode/Vbt/Vbt.json @@ -23891,7 +24584,7 @@ }, { "WidgetType": "Label", - "WidgetName": "VBT Version: 240", + "WidgetName": "VBT Version: 250",^M "Visibility": "", "Data": [], "HelpText": "", Vladimir (φ-coder) also published the tool intelvbtupgrader [2] to address this problem. I would have assumed that FSP versions would be backwards compatible. I attache the output of `intel_vbt_decode` of both VBT files. Does somebody have more insight?
