Chainloading Windows from a Linux Payload

by Matt B

Greetings, From what I can find, Linux can only chainload another linux kernel. (via kexec) Does this mean that a Linux payload like LinuxBoot cannot be used to boot Windows or another OS, either directly or by chainloading another payload from CBFS? It's nice that a Linux payload can provide superior flexibility and configurability than UEFI with the added benefit of a battle-hardened environment, but the ability to only boot a Linux OS seems like a pretty significant limitation (if this is indeed the case). Sincerely, -Matt

ASUS KCMA-D8 RAM issues

by up6IfzRzvQCyv9AK4XvYirxDa8

Hello, I bought the motherboard ASUS KCMA-D8 to set up a coreboot + Qubes OS workstation. However, I don't find a combination of coreboot + CPU + RAM that works. I have also tried the latest libreboot and it works in most cases, but does not provide microcode updates. For test purposes I tried 41xx/42xx/43xx Opterons. The error message I get in most cases on the serial null-modem port is: DIMM training FAILED! Restarting system...soft_reset() called! I following RAM modules has been used: - M391B1G73BH0-CK0 (8GB PC3L-12800 UDIMM ECC) // NOK - NT8GC72B4NB1NK-CG (8GB PC3PC3-10600 RDIMM ECC) //NOK - HMT325U7BFR8A (2GB PC3-10600 UDIMM ECC ) //OK, see https://www.raptorengineering.com/coreboot/kcma-d8-status.php There are also differences between 42xx and 42xx/43xx. Below a logfile of coreboot 4.9 with 4225 and 4180. Test with 4365 + coreboot 4.9 and 1x M391B1G73BH0-CK0 in the Slot A2 and 1x CPU. The same configuration but with the HMT325U7BFR8A (recommended by raptorengineering.com) works. I tried many combinations of RAM modules + CPU + coreboot versions (4.6, 4.7, 4.8, 4.9) but get the above "DIMM training FAILED..." error message in most cases. Any ideas or recommendations for RAM modules that are supported so that a workstation with 32GB or better 64GB can be built? Or why libreboot works and coreboot doesn't? Thank you. 4225 / #005.log (1x NT8GC72B4NB1NK-CG) // NOK ====================================== coreboot-4.9 Wed Dec 19 18:05:51 UTC 2018 romstage starting... .. ..

BUG: Seabios choose the wrong option rom when two are available

by akjuxr3＠dismail.de

In this thread https://mail.coreboot.org/hyperkitty/list/coreboot@coreboot.org/thread/FT... we found a bug in seabios. Its choosing the wrong option rom in the case when for example on a Intel G41 board you have the internal Intel GPU and have added a external PCIe GPU. Then coreboot switches over to the external GPU for the graphical output but seabios use the option rom for the Intel G41 GPU. In case of x4x/G41 this results in no ability to have a graphical boot mode and thus its not possible to boot some linux live images. In the linked thread a workaround is been found: "In the "Devices" menu of coreboot, set "Graphics initialization" to "None" ". This breaks the functionality to have coreboot output with the internal GPU when you pull out the PCIe GPU. The switch should happen automaticly and without the need to recompile/reconfigure coreboot. Changes like https://review.coreboot.org/c/coreboot/+/18504 was made to make this happen. Would be great if this seabios issue could be fixes. Thanks!

How to enable the SMBus0 in coreboot for Intel Atom C2000?

by dponamorev＠gmail.com

There is motherboard based on the Intel Rangeley Atom C2000 (C2758) series processor. How to enable the SMBus0 in coreboot? If I use OEM BIOS or BIOS from Intel (EDVLCRB1.86B.0048.R00.1508181657_MPK) for mohon peak crb, then I see on the SMBus0 (i2c-1 in Fedora 28) memory DIMM spd (0x50 & 0x52), clock generator (0x69) and other devices. If I use a coreboot based bios for the Mohon peak platform - I do not see any devices on i2c-1. I see an data exchange on the SMBus0 with oscilloscope at boot time only. When I send "i2cdetect -y 1" command in Linux no activity on SMBus0 and no device found.

"remote: You need 'Create' rights to create new reference" when pushing to Gerrit

IME: Alternatives for large companies?

by Philipp Stanner

Recently I had an interesting discussion with a system administrator who is responsible for several hundred PCs, Routers etc. His argument was: Imagine it would take you 15 minutes to install a patch on a computer (all windows machines of course...). If your company has 1000 computers and you send one admin to install the patches, it will take him >31 work days, working 8h a day. That's why, he said, companies are interested in software allowing them to install stuff on the OS / hard drive remotely through the firmware I, not dealing with large networks, had never thought about it this way. But it does make a lot of sense to me, it's about real money (as usual). So I guess that's indeed a huge reason why Intel and AMD created Frankenstein, running below UEFI and Kernel. It probably doesn't explain so much why it's necessary to disallow you switching IME off or why it needs control about absolutely everything, but that's a different story. So I'm wondering: What would you do about this reality? Could there be a different solution other than software in Ring -1 having its sausage fingers on everything? Sure, the programmers in a company could install their stuff on their own, but the office folks, the HR and PR guys and the lawyers? Hmm. And whether we like it or not, even awesome companies almost exclusively supply their employees with windows machines and they just demand solutions allowing their IT-departements to fix everything as cheap and as easy as possible P.

Starting the coreboot 4.10 release process

by Patrick Georgi

Hi everybody, with this mail I'm officially starting the 4.10 release process. As per the first step of our checklist (Documentation/releases/checklist.md), I hereby announce the intent to release coreboot 4.10 in about 2 weeks. I'm aiming for May 28th to avoid releasing into the weekend or on Memorial Day in the US, but I'll likely lock down the commit we'll designate 4.10 during those days to give some room for testing. I created a copy of the checklist on https://piratenpad.de/p/coreboot4.10-release-checklist, also including the current state of the 4.10 release notes. Please test the boards you have around and provide fixes, please be careful with intrusive changes (and maybe postpone them until after the release) and please update the release notes (Documentation/releases/ coreboot-4.10-relnotes.md or near the bottom of the etherpad doc, I'll carry them over into our git repo then). As promised with the 4.9 release there won't be deprecations after 4.10. However we need to finalize our set of deprecations we want to announce with 4.10 that will happen after the 4.11 release (those also belong in the release notes). Regards, Patrick -- Google Germany GmbH, ABC-Str. 19, 20354 Hamburg Registergericht und -nummer: Hamburg, HRB 86891, Sitz der Gesellschaft: Hamburg Geschäftsführer: Paul Manicle, Halimah DeLaine Prado

PSPTool – Display, extract, and manipulate PSP firmware

by Christian Werling

Hi everyone, over the past year I did some research on AMD’s controversial Secure Processor (formerly known as Platform Security Processor or PSP). Its firmware is stored in an undocumented area of UEFI images and so I wrote a tool that can parse it. I thought some of you might be interested in that: https://github.com/cwerling/psptool <https://github.com/cwerling/psptool> It is accompanied by PSPTrace, which can correlate an SPI capture of a boot procedure to the AMD firmware entries so you can deduct some boot logic from it. Cheers, Christian

nvramtool and CONFIG_HAVE_OPTION_TABLE (or CONFIG_USE_OPTION_TABLE)

by kevin＠trippers.org

A coworker noticed that nvramtool (and the nvramtool man page) both refer to the option CONFIG_HAVE_OPTION_TABLE as the option set to include cmos.layout into the coreboot tables. nofound_msg_cmos_opt_table[] = "%s: Item %s not found in coreboot table. Apparently, the " "coreboot installed on this system was built without specifying " "CONFIG_HAVE_OPTION_TABLE.\n"; However, CONFIG_HAVE_OPTION_TABLE is set by the board to indicate whether the board is cmos.layout capable. The actual option is CONFIG_USE_OPTION_TABLE, which depends upon CONFIG_HAVE_OPTION_TABLE. The code in src/lib/coreboot_table.c only adds the lb record to the coreboot tables if CONFIG_USE_OPTION_TABLE is set. The other choice is to make src/lib/coreboot_table.c add the lb record if the board has a cmos.layout (CONFIG_HAVE_OPTION_TABLE) but then userland will have access to a layout that is ignored. I suppose this is what happens if you set CONFIG_STATIC_OPTION_TABLE. This doesn't seem like the right answer to me. I think this is only cosmetic, but should I submit a patch to change this so that others are not also sidetracked? Thanks, Kevin
