OpenBSD won't install on an x220 Thinkpad with Coreboot
by Robert Milton 12 Apr '20

12 Apr '20

I'm trying to get OpenBSD to install on an x220 Thinkpad with Coreboot/SeaBIOS but I'm running into two problems: the ethernet device doesn't work and OpenBSD doesn't detect my HDD. dmesg said em0 wouldn't load because the EEPROM had an invalid signature. I have no idea why OpenBSD doesn't see my HDD though. It's strange because everything works fine under Linux. And I cannot seem to mount a usb drive under the OpenBSD installer to attach dmesg errors. I originally posted this as a bug report to bug report mailing list but Theo said it would be better suited for Coreboot's and wasn't a bug in OpenBSD.

Optiplex 790 now has preliminary support by coreboot

https://review.coreboot.org/21774 In case anyone else didn't notice - It is a sandy/ivy system with IOMMU. This is great and should help get coreboot in to the corporate user world.

Re: [coreboot] [LinuxBoot] FOSDEM 2019 deadline today
by Carl-Daniel Hailfinger 01 Feb '19

In that case, I'd also like to point you to the deadline for submitting main track talks which is tomorrow(!). https://fosdem.org/2019/news/2018-08-10-call-for-participation/ Having a coreboot/LinuxBoot talk there would be awesome. Ron/David, could you submit something or do you have someone in mind who can do that? There's also lightning talks, deadline is a bit later. OK, I'm submitting a request for a stand. I need a backup contact for the stand. Who is willing to do that? AFAICS we can still change the backup contact later if life happens.

Re: [coreboot] Upgrade the 12 years old LZMA libraries - should we do it?

Do you have any numbers for this? An improved compression ratio and improved speed would be nice indeed, but how does the size of the decompression code change? If the decompression code grows more than the size reduction from better compression, it would be a net loss. A significantly reduced decompression speed would also be a problem. Decompression speed would have to be measured both for stream decompression (i.e. the decompressor gets the compressed data in single-byte or multibyte chunks) as well as full-size decompression (i.e. the decompressor can access all compressed data at once). We also have to make sure that stream decompression still works after the change. > Do you think it should be done, or you are OK with using such an > outdated version? A size benefit for the resulting image is a good reason to switch. Regards, Carl-Daniel

Testing modernizing patches on ASUS KGPE-D16. (was Re: Asus KGPE-D16 with latest coreboot errors with Unsupported Hardware on Qubes 4 install missing IOMMU?)
by Daniel Kulesz 22 Jan '19

22 Jan '19

Hi folks, is there a branch that has all the outstanding KGPE-D16 changes merged? I will be happy to test, but I feat I won't find the time to test all those fixes each in a separate branch. Also some specification of what tests need to be conducted would help. The outstanding KGPE-D16 bugs on my personal list are boot failures that require to turn off/on AC and the power consumption issues in idle that forced me to pull out one of the CPU packages and its RAM. But as far as I understood these were not targeted in the recent changes but could be "accidentially" fixed (e.g. by removal of some old buggy code) - correct? Cheers, Daniel

Coreboot build process with gcc 8.1
by Salvatore Bellizzi 11 Jan '19

11 Jan '19

Hi, I have a question reguarding the build process. Since crossgcc has been updated and gcc is now at version 8.1 I always encounter an error when building coreboot: coreboot/src/console/vtxprintf.c:102: undefined reference to '__udivmoddi4' Since coreboot uses crossgcc and its own libgcc libraries, I figured that the __udivmoddi4 function has not yet been implemented. Anyway I have incurred in this failure several times and even with the latest 4.9 release. Shouldn't I be able to build at least this latest release using unmodified crossgcc or am I missing something else? thanks, salvatore

Please help me adapt coreboot to HiFive-Unleashed
by 王翔 07 Jan '19

07 Jan '19

I tried to adapt coreboot to HiFive-Unleashed and boot bbl with coreboot and run linux. My changes are as follows: https://github.com/hardenedlinux/coreboot-HiFiveUnleashed/tree/HiFive-Unlea… My code can run bbl, but it doesn't respond when bbl exits m-mode and enters linux. I use freedom-u-sdk to compile bbl. In order not to conflict with the coreboot memory address, execute the following command. riscv64-elf-objcopy --change-addresses 0x200000 work/riscv-pk/bbl ../coreboot/payload.elf I don't know what I missed, what should I do, I hope to get your help. ------------------ 王翔安全研究员广州市腾御安信息科技有限公司广州市天河区珠江新城华穗路406号保利克洛维二期中景A座1020-1024

by Ivan Ivanov 31 Dec '18

Had a lot of access problems recently, both to coreboot website and its' repositories. Was it a DDoS attack? How to make sure that the sources at review coreboot repository haven't been modified during this event? Best regards, Ivan

Update on Asus KGPE-D16 with coreboot 4.6 and Qubes 4
by petecb 31 Dec '18

31 Dec '18

Hi, Season's greetings to everyone! :-) I've been able to get my Asus KGPE-D16 running with coreboot 4.6 and Qubes 4 and I'm pleased to report it has been nice and stable over the holiday period, save for a few minor issues. Suspend works fine on a fresh install of Qubes 4, however applying the latest updates then stops this from working. (It goes in to suspend but does not resume properly). I'm assuming this is now a Qubes issue. My Intel Optane 900p NVME drive does not work reliably with Qubes 4. It initially appears fine but anywhere between 4-12 hours after boot the system will panic and switch to a read-only file system - you can't run any commands without an "Input/Output Error" even in Dom 0. The only course of action when this is encountered appears to be a hard reset. Unsurprisingly, getting any kind of logs about what is actually happening has proven fruitless so far :-( I have therefore switched to a normal SATA drive for the last week and this has been nice and stable. I suspect my best course of action to get a higher performing filesystem is to move to 4 SATA SSDs in RAID 10. If anyone has any other suggestions to get faster drive access with this platform (particularly good random read/write performance for using lots of concurrent VMs in Qubes) or possible approaches to fix my NVME drive issue, they would be much appreciated. My only other minor issue at the moment is lack of fan control. If I run "sudo pwmconfig" in dom0 I get the message "There are no pwm-capable sensor modules installed". I suspect I need to enable some additional modules, so if anyone can provide me some explicit directions on how to do this, it would again be much appreciated. Kind regards, Pete
