Linux framebuffer-coreboot driver unusable with arm64 Chromebooks
by Alper Nebi Yasak 28 Jan '23

28 Jan '23

Hi, I've been experimenting with Linux's coreboot framebuffer driver on a google/gru (kevin) chromebook with stock firmware. I get these kernel messages: platform simple-framebuffer.0: failed to claim resource 0: [mem 0x00000000-0x00ea5fff] coreboot: could not register framebuffer framebuffer: probe of coreboot7 failed with error -16 When I tried to print the coreboot table struct in kernel I saw the framebuffer physical address is 0. Browsing coreboot sources led me to a "rockchip/rk3399: display: Do not allocate framebuffer in coreboot" [1] commit, which says it's "dynamically chosen by libpayload now". I think the coreboot tables should be updated after this, but aren't. [1] https://review.coreboot.org/c/coreboot/+/17109/ I suspect `set_vbe_mode_info_valid(&edid, (uintptr_t)0);` is the point of interest there, which is now `fb_new_framebuffer_info_from_edid`, which is in a few more files: $ git grep "fb_new_framebuffer_info_from_edid(.*0);" src/mainboard/google/asurada/mainboard.c: ... src/mainboard/google/cherry/mainboard.c: ... src/mainboard/google/corsola/display.c: ... src/mainboard/google/geralt/display.c: ... src/mainboard/google/herobrine/mainboard.c: ... src/mainboard/google/kukui/mainboard.c: ... src/mainboard/google/oak/mainboard.c: ... src/mainboard/google/trogdor/mainboard.c: ... src/soc/rockchip/rk3399/display.c: ... I don't quite know how to solve this, but was told to report it to the mailing list.

No Coreboot on system76 dekstops
by teacher＠tutanota.com 26 Jan '23

26 Jan '23

Hello, I checked the vendor section of the coreboot website which states that System76 sells desktops and laptops with Coreboot. While system76 does sell laptops with coreboot, I couldn't find any clear statement regarding their desktops on system76's website. I contacted them previous week to verify that info and it turns out their desktops do not include Coreboot. Here is part of the answer that was given to me by the sales team on 10th of January 2023:" We have not yet ported Coreboot to any of our desktop models, they are all currently using proprietary motherboard vendor firmware." So I would recommend deleting the reference to their desktops on coreboot's website as it's a bit misleading. By the way, I couldn't find any company selling desktops with Coreboot preinstalled. At all. Crap, things have to change :) ! Cheers. Julien Danglard professeur de français -- Tutanota respects your privacy and it's for free, try it ! https://tutanota.com

coreboot/LinuxBoot on Supermicro server boards
by Paul Menzel 23 Jan '23

23 Jan '23

Dear coreboot folks, A colleague made me aware of the presentation *The OSF on Supermicro's platform* [1] by the Supermicro employees Hancock Chang and Simon Chou¹ at the OCP Global Summit 2022 this October. This is great news. I would have loved to also read about this on the coreboot mailing list. In the talk, the board Supermicro X12SPW is mentioned, and that it’s planned for the X13 series. One of our suppliers responded though, that systems with coreboot are currently not generally available, but it’s something Supermicro offers to ODMs or for projects with large volumes. The slide *Call to Action* contains: > Come and collaborate with Supermicro Collaboration would be great. A first step would be, if Supermicro (engineers) would get in touch with the coreboot project/community on the mailing list, and also upstreamed their work and contributed their improvements. Judging from the presented times, there is still a lot of potential to unlocked, and where the coreboot community already has a lot of experience in to share to make sure, the Supermicro boards work even better. Kind regards, Paul PS: OpenBMC patches are already being sent upstream [2]. ¹ Hopefully correct addresses in Cc. At least my test message did not bounce.

Power button only works once - where to check for fixes (51nb X2100)?
by Rafael Send 18 Jan '23

18 Jan '23

Hi, As folks may have gathered from my other question about the GCC build environment, I've been playing around with the old X2100 port ( https://github.com/mjg59/coreboot/tree/x2100_ng). I got it to build and added the latest version of MrChromebox's Tianocore, but there's still one issue that keep is from being very useable. After flashing / plugging in the machine, the power button will turn it on, but only once. If I shut down any OS, or even if it goes to sleep or suspends, the power button no longer has any effect so the only "fix" is currently to unplug power and re-plug it. Where might I look for causes of this? Is it a shutdown state thing? ACPI? Thanks, Rafael

Mac Book Air 2019 firmware update
by Ivan Cubillas Castellanos 16 Jan '23

16 Jan '23

Hi everyone, Thank you in advance for your attention and I am sorry for my low english level, I am Spanish. I have a doubt because a friend give me as a gift a 2019 macbook air with an I5 Amber Lake processor. This Macbook Air has an Activation Lock with an unknown apple ID, I think that an interesting option could be change this OS for an Ubuntu version, I can boot Mac Book Air in DFU mode, but I am not sure if I coreboot option will be possible and how I can compile or install it, in order to substitute mac os recovery mode. Is it possible? Thank you very much in advance for reading my question, Regards Ivan.

cross-repo-cherrypick and re-writing Signed-off-by's
by Nico Huber 16 Jan '23

16 Jan '23

Hi fellow coreboot developers, it was pointed out to me that I didn't do exactly what Chromium developers are used to (i.e. what util/scripts/cross-repo-cherrypick does) when picking patches to flashrom-stable. The major difference is that I didn't prepend Signed-off-by tags with an `Original-`. My reasoning was that it applies to the work in a patch and not the exact commit. We also don't change these tags when clicking Submit in Gerrit which also triggers a cherry- pick. Prepending the `Original-` to all the tags that are automatically added by Gerrit makes perfect sense to me, OTOH. So here's the question: Is there a particular reason that `cross-repo-cherrypick` prepends the Signed-off-by or is that just done because it treats all tags the same? Cheers, Nico

[coreboot - Bug #314] (Rejected) Please disable 'administrator approval' on ticket.coreboot.org
by Martin Roth 15 Jan '23

15 Jan '23

Issue #314 has been updated by Martin Roth. Status changed from New to Rejected Not a coreboot bug. closing ---------------------------------------- Bug #314: Please disable 'administrator approval' on ticket.coreboot.org https://ticket.coreboot.org/issues/314#change-1373 * Author: akjuxr3 akjuxr3 * Status: Rejected * Priority: Normal * Category: infrastructure * Start date: 2021-07-30 ---------------------------------------- Please disable this 'administrator approval' on ticket.coreboot.org. It feels like discrimination. Before i have written the first word on ticket.coreboot.org i have to be approved by someone by hand without this person knowing anything from me. I had to wait several days for this approval. Its completely unclear what is been tracked. Have the IP-address used for registration been tracked? Have the used email-address been tracked? E-mail-address-discrimination is illegal in many countries and this is completely breaking the freedom of choice! Username? Choosing (user)names is up to the user and making decision based on what names are 'allowed' to enter a platform is the most racist thing possible. Conclusion: This 'administrator approval' is sort of discrimination i have not seen for years on free projects! There is no data available at the registration process that could or should be used to decide who is allowed to report a bug in the coreboot project. Please disable this discrimination that is stopping people for days or even forever to report a coreboot issue. -- You have received this notification because you have either subscribed to it, or are involved in it.
