[coreboot - Bug #432] (New) t440p reboots on suspend
by Josh R 15 Jan '23

Issue #432 has been reported by Josh R. ---------------------------------------- Bug #432: t440p reboots on suspend https://ticket.coreboot.org/issues/432 * Author: Josh R * Status: New * Priority: Normal * Target version: none * Start date: 2022-10-21 * Affected versions: 4.15 * Related links: https://ticket.coreboot.org/issues/412 * Affected hardware: Lenovo t440p * Affected OS: Ubuntu 22.04 (Pop OS) ---------------------------------------- Per request, adding new ticket for an issue with my t440p where attempting to resume on suspend results in a reboot (or at least, not resuming from DRAM). My t440p already has coreboot installed (via osbmk). Following instructions from issue #412, I have attempted the following: `sudo flashrom -p internal --ifd -i bios -w the_full_12MiB_osbmk.rom --noverify-all` ...but that did not seem to do the trick (still "restarts" without resuming from RAM). Note that I am using the "full" 12MB osbmk rom (not split by 4MiB and 8MiB, as that seemed intended for the hardware flashing instructions). coreboot version looks like 4.15.204, and flashrom version 1.2-640. If it helps, attached cbmem -1 output with a "normal boot" followed by a later resume from suspend (that resulted in a restart). Thanks in advance. I guess you don't realize how much you use suspend until it doesn't work anymore :) ---Files-------------------------------- cbmem.20221019195923.normal_boot.log (36.2 KB) cbmem.20221019200724.from_suspend.log (36.3 KB) -- You have received this notification because you have either subscribed to it, or are involved in it.

Issue #387 has been reported by Jun Aruga. ---------------------------------------- Support #387: Support Framework Laptop https://ticket.coreboot.org/issues/387 * Author: Jun Aruga * Status: New * Priority: Normal * Category: board support * Target version: none * Start date: 2022-06-05 * Affected hardware: Framework Laptop ---------------------------------------- Dear coreboot developers, I am a user of Framework Laptop[1][2]. Thank you for working to make coreboot work on Framework Laptop! This ticket is to track the task, as I didn't see any other issue tickets about Framework Laptop here. According to the Framework founder's comment[3] below, Framework provided Framework Laptops to the coreboot community. > We've handed three systems that can boot unsigned bootloaders to folks in the coreboot community. Our plan in the near term is to help them create a shim loader that can be signed to run on any Framework Laptop, which then enables anyone to do further coreboot development. Then I saw Matthew's try to make the coreboot work on Framework Laptop,[4] but unfortunately it didn't work at that time.[5] How is the current status? What prevents coreboot from working on the Framework Laptop? How can we, people in the Framework community, help you? As a reference, there is a coreboot specific thread on the Framework community forum.[6] ## References * [1] https://frame.work/ * [2] Framework Computer - Wikipedia - https://en.wikipedia.org/wiki/Framework_Computer * [3] Framework Laptop Mainboard, Hacker News, April 20, 2022 - https://news.ycombinator.com/item?id=31097434 * [4] Matthew tries to port Coreboot to the Framework laptop - February 27, 2022 - https://www.youtube.com/watch?v=Jf_6xW-8tfQ * [5] Matthew Garrett on Twitter, February 27, 2022 - https://twitter.com/mjg59/status/1497788538212917250 * [6] Free the EC! and Coreboot Only - https://community.frame.work/t/free-the-ec-and-coreboot-only/791 -- You have received this notification because you have either subscribed to it, or are involved in it.

[coreboot - Cleanup #421] (New) Change API of functions taking hash as an argument
by Krystian Hebel 13 Jan '23

13 Jan '23

Issue #421 has been reported by Krystian Hebel. ---------------------------------------- Cleanup #421: Change API of functions taking hash as an argument https://ticket.coreboot.org/issues/421 * Author: Krystian Hebel * Status: New * Priority: Normal * Target version: none * Start date: 2022-10-12 ---------------------------------------- All existing functions that take a digest as an input assume that only one hashing algorithm is used at a time. Crypto agile format entry can (and should) log every used PCR bank in one entry for a given measurement. To make it work, some of the arguments must be changed, e.g.: - pass number of algorithms used; - instead of algorithm ID, pass a pointer to array of such IDs, with size equal to above; - instead of hash, pass a pointer to array of hashes, with size and order as above. -- You have received this notification because you have either subscribed to it, or are involved in it.

Trouble building coreboot early stages
by Gabriel Malaspina 02 Jan '23

02 Jan '23

Hello, I'd like to build coreboot for HP Elitebook 8570w but I keep running into trouble. I'm trying to build /coreinfo/, following the 1st part of the tutorial <https://doc.coreboot.org/tutorial/part1.html> to the letter, but it simply doesn't work. Initially I'd get an error involving /libpayload/; I got it compiled and installed following instructions in /README/ and now I'm getting the following: ... ... AR /home/gabriel/coreboot/payloads/coreinfo/libpayload/libpayload.a CC arch/x86/head.head.o.o CP /home/gabriel/coreboot/payloads/coreinfo/libpayload/head.o LPGCC coreinfo.bin /home/gabriel/coreboot/util/crossgcc/xgcc/i386-elf/bin/ld.bfd: cannot find -lpayload /home/gabriel/coreboot/util/crossgcc/xgcc/i386-elf/bin/ld.bfd: cannot find libgcc.a: No such file or directory collect2: error: ld returned 1 exit status make: *** [../libpayload/Makefile.payload:93: build/coreinfo.bin] Error 1 make: Leaving directory '/home/gabriel/coreboot/payloads/coreinfo I'd guess it's a matter of unsatisfied dependencies but I don't understand /make/ files, as of yet at least. Anyone that could point me in any direction? Thanks, Gabriel.

Re: Cisco Meraki use coreboot in some MX products and will not provide the source code
by Martin Roth 02 Jan '23

02 Jan '23

Also, I think I tracked down the commit that that tree was based on: 5d0601767f vendorcode/amd/agesa/fam10: Build as a static library (2014-12-08) Method: I believe that coreboot's most changed file is /Makefile.inc, so I checked out every revision of that file and compared it to their Makefile.inc. That narrowed it down to somewhere in this range: Commit ID: 5839635add, Lines Different: 35 Commit ID: a234f45601, Lines Different: 0 Commit ID: 24cca75b47, Lines Different: 4 Here's the command: ``` for commit in $(git log --pretty=%h 4.0..origin/master <http://4.0..origin/master> -- Makefile.inc); do git checkout $commit >/dev/null 2>&1; printf "Commit ID: %s, Lines Different: %s\n" "$commit" "$(diff Makefile.inc ../coreboot-mx84/Makefile.inc | wc -l)" ; done ``` Then taking the commit ids before and after the identical Makefile.inc, I did a diff of the entire tree to find the minimum: Commit ID: b713d93525, Lines Different: 1391 Commit ID: a3a722c5fc, Lines Different: 1382 Commit ID: 5d0601767f, Lines Different: 1366 Commit ID: fd1349bb49, Lines Different: 1945 Commit ID: 99a3bba171, Lines Different: 2882 And the command: ``` for commit in $(git log --pretty=%h 24cca75b47..5839635add); do git checkout $commit >/dev/null 2>&1; git reset HEAD --hard >/dev/null 2>&1; printf "Commit ID: %s, Lines Different: %s\n" "$commit" "$(diff -r /work/git/coreboot-https /work/git/coreboot-mx84 | wc -l)" ; done ``` Looking at what's contained in the repo on github, I'd probably delete crossgcc/xgcc and crossgcc/tarballs from git, but that's up to you. Hope this helps. Martin Dec 22, 2022, 14:10 by coreboot(a)coreboot.org: > Hi Hal, > Thanks for bringing this up.
