About device tree in Coreboot
by Chiang.Gain 江有舜 TAO 20 Apr '23

20 Apr '23

Dear Sir This is Inventec BIOS team, we are trying to port Coreboot to our Server Board which is based on Intel CRB ArcherCity. We have to add “Devicetree.cb” files under mainboard folder, right ? We had read the following files but we are still confused and don’t know how to modify those files to match our design. Documentation/getting_started/devicetree.md Documentation/drivers/dt_entries.md We would like to know if there are any training materials or further Docs; particular to “syntax”. that we can refer to. Any kind of helps are appreciated.

Request for comments on removing NE2000 console support
by Martin Roth 20 Apr '23

20 Apr '23

The NE2000 was a fantastic card back in its day, but as far as I can tell, that day is long past. Is anyone using this feature? Does it make sense to keep it in the master branch? The code, as far as I can tell, is not problematic, but I also don't know whether or not it's still working. Its implementation really only consists of two files plus sections of Kconfig and a Makefile. If it's not being used anymore, I'd like to propose that we remove the NE2000 console support from the master branch. If it is being used by anyone, there's a request to update the description in src/console/Kconfig. Thanks everyone. Martin

coreboot 4.20 release scheduled for May 1, 2023
by Martin Roth 20 Apr '23

20 Apr '23

Hi All, When we did the last release, we had hoped to be able to get the 4.20 release out today (4/20 in the US). Unfortunately, the release team was not ready, so the release has been pushed out to 5/1. As always, please test any boards, and give feedback. We'll include any known issues from the bug tracker in the release notes going forward, so please file bugs if there are any issues. Please mark any commits that you specifically want to go into the release with the `coreboot_release_4.20` hashtag. If you're not familiar with hashtags, you can set them by clicking the "show all" button at the top left of the screen in gerrit, then clicking the "hastags" edit icon. It's recommended to avoid merging any heavy new features between now and the release date. If there are any obsolete code paths that should be removed in 6 months, please bring them up in the mailing list now. Current statistics since the 4.19 release: - Total Commits: 1273 - Average Commits per day: 13.49 - Total lines added: 85872 - Total lines removed: 30755 - Number of patches adding more than 100 lines: 109 - Total difference between added and removed: 55117 - Total authors: ~150 - New authors: ~25 Added 22 mainboards: ------------------- * ASROCK B75M-ITX * Dell Inc.

Working X11SSH-F config
by Martin Kjær Jørgensen 20 Apr '23

20 Apr '23

Hello, I have recently started experimenting with coreboot so please forgive my ignorance :-) I can make it boot using edk2 payload and only flashing "bios" region and I am able to make an ordinary linux distro boot. Using OEM BIOS from supermicro everything seems to work as expected, but using my coreboot image I run into the following issues: 1. I also get PCI related errors and warnings during coreboot boot. 2. Microcode update errors during coreboot boot, although it claims microcode to be updated afterwards. 3. My mainboard have 2 Intel NICs but Linux kernel claims only 1 exists, and lspci only shows 1. The "first" one :-) . 4. Coreboot does not show up, or work, if BMC is not enabled using the jumper. 5. When Linux issues system reset, machine freeze and needs to be manually powered off. If issuing "power off" the machine powers off as normal. Have anyone got a fully "working"/"stable" config for their X11SSH-* board I can use as reference? I got the feeling I'm missing something obvious or needed tweaks ... /Martin

Is my PC compatible with the Coreboot bios?
by Cédric LACHAUD 18 Apr '23

18 Apr '23

Hello, I am contacting you because a year and a few months ago, I bought a PC assembled by the company NovaCustom (model NH77) and I would like to know if I can install Coreboot as a BIOS without risk for my PC. I specify that I did not find the "official" name of my motherboard (which is, according to my current BIOS - InsydeH20 - NH5x_7xDPx). When I go to my Windows 11 (in the msinfo32 tool), the manufacturer of my motherboard would be "Notebook". Here is the result of the commands you wanted to be addressed for any such questions: * lspci -tvnn -[0000:00]-+-00.0 Intel Corporation 10th Gen Core Processor Host Bridge/DRAM Registers [8086:9b54] +-01.0-[01-05]--+-00.0 NVIDIA Corporation GA106M [GeForce RTX 3060 Mobile / Max-Q] [10de:2520] | \-00.1 NVIDIA Corporation Device [10de:228e] +-02.0 Intel Corporation CometLake-H GT2 [UHD Graphics] [8086:9bc4] +-12.0 Intel Corporation Comet Lake PCH Thermal Controller [8086:06f9] +-14.0 Intel Corporation Comet Lake USB 3.1 xHCI Host Controller [8086:06ed] +-14.2 Intel Corporation Comet Lake PCH Shared SRAM [8086:06ef] +-15.0 Intel Corporation Comet Lake PCH Serial IO I2C Controller #0 [8086:06e8] +-15.1 Intel Corporation Comet Lake PCH Serial IO I2C Controller #1 [8086:06e9] +-16.0 Intel Corporation Comet Lake HECI Controller [8086:06e0] +-17.0 Intel Corporation Device [8086:06d3] +-1b.0-[06]----00.0 Samsung Electronics Co Ltd NVMe SSD Controller SM981/PM981/PM983 [144d:a808] +-1d.0-[07]----00.0 Samsung Electronics Co Ltd NVMe SSD Controller SM981/PM981/PM983 [144d:a808] +-1d.5-[08]----00.0 Intel Corporation Wi-Fi 6 AX200 [8086:2723] +-1d.6-[09]--+-00.0 Realtek Semiconductor Co., Ltd.

WARNING: No chipset found. Flash detection will most likely fail. ======================================================================== You may be running flashrom on an unknown laptop. We could not detect this for sure because your vendor has not set up the SMBIOS tables correctly. Some internal buses have been disabled for safety reasons. You can enforce using all buses by adding -p internal:laptop=this_is_not_a_laptop to the command line, but please read the following warning if you are not sure. Laptops, notebooks and netbooks are difficult to support and we recommend to use the vendor flashing utility. The embedded controller (EC) in these machines often interacts badly with flashing. See the manpage and https://flashrom.org/Laptops for details. If flash is shared with the EC, erase is guaranteed to brick your laptop and write may brick your laptop. Read and probe may irritate your EC and cause fan failure, backlight failure and sudden poweroff. You have been warned. ======================================================================== The following protocols are supported: None. No EEPROM/flash device found.

I left out the complete lspci you sent, but attached here is the relevant section. It is PCI 0:1.1 and 0:1.2 that require different configuration from what stock coreboot now does. I think the patch I sent previously has a fair likelihood of working. Auto-detection or a choice in menuconfig is something that can come later. Kyösti

SMSC- EMC2300 driver
by Ahmet Fenerci 14 Apr '23

Hello, We have an Intel (Denverton, cpu:C3758) Harcuvar custom board. We use SMSC-EMC2300 fan controller in the board. It works on i2c bus but driver not available. Is it possible to add SMSC-EMC2300 driver in coreboot? Kind regards, Ahmet FENERCİ

X200 GPU slowdown that needs to be cured by S3
by Artem Mazurov 13 Apr '23

13 Apr '23

Hello. Whenever I try to run any program that uses 3D acceleration (like glmark2), after a short while performance drops significantly (From 14 FPS running terrain benchmark to 3 FPS) and persists until S3. What could be the problem and how can I troubleshoot this? Since S3 fixes it, maybe it's something with coreboot? cbmem.log attached.

Supermicro X11SSH-LN4F PCI-e bifurcation?
by Tomas 13 Apr '23

13 Apr '23

Hi, I installed Coreboot with SeaBIOS on a Supermicro X11SSH-LN4F. The stock BIOS can read two NVMe drives in a Dual m.2 splitter card inserted in the middle slot 5 on the motherboard. But coreboot can not. In the coreboot nconfig menu there is no setting that will enable bifurcation of the x8 slot to x4x4. Is this something that is configurable in any way? /Tomas
