[GSoC-23] Introductory mail
by Aditya Jha 08 Mar '23

08 Mar '23

Hello I am Aditya Ranjan Jha, I am a third year undergraduate student interested in OS, computer systems and architecture. I am interested in some of the project ideas of this edition of GSOC: 1) Support Power9/Power8 in coreboot 2) Learn hardware behavior from I/O and memory access log I wish to connect with the mentors to get better insights about the work to be carried out

How To Get Coreboot On Dev One
by Sergio 07 Mar '23

07 Mar '23

Hello, Is there a service that you provide or know of that can change my HP Dev one to coreboot? I am new to Linux so pardon my ignorance... Thank you in advance, Sergio

Is it possible to merge Gerrit accounts?
by Kevin Keijzer 06 Mar '23

06 Mar '23

Hello, I have been trying to add my e-mail address to my account on Gerrit, but I keep getting the error message it's already in use by a different account. I have always used GitHub OAuth to sign in, so I'm not sure what went wrong, but it looks like Gerrit has two user accounts for me: https://review.coreboot.org/q/owner:kkeijzer and https://review.coreboot.org/q/owner:kevin%2540quietlife.nl As I only have access to the former account and not to the latter - which does have my e-mail address associated with it - I was wondering if it would be possible to either merge these accounts, or remove the e-mail address from the old account. Note that I never wanted to send this to the general mailing list, but I don't know who the admins of Gerrit are. Otherwise I would have contacted you directly. Feel free to reply off-list to follow up. Thanks in advance. -- With kind regards, Kevin Keijzer

Getting onboard NIC recognized as enoX instead of enpXsX
by Kevin Keijzer 06 Mar '23

06 Mar '23

Hello, I've been trying to figure out how predictable interface naming works, especially the "on-board index number", that the firmware apparently passes(?) I'm currently working on a port for the ASRock B75M-ITX, which has a Realtek NIC as PCI device 03:00.0. The Linux kernel calls this device enp3s0, which makes sense and works fine. However, on my ASUS P8Z77-V and my Lenovo X230, the Intel NIC is called eno0, which makes more sense, because it's "ethernet onboard 0" and not a physical network card stuck in a PCI Express slot. At first I thought that maybe this was an e1000e-specific way of naming interfaces, but at the office I have an old Gigabyte GA-G41M-ES2L-based file server, running coreboot, also with a Realtek NIC, also being PCI device 03:00.0, which is called eno0 by the kernel as well, with enp3s0 as altname. (So it's not that.) I ended up reading about the interface (re)naming process, which seems to be handled by systemd-udevd [1]: --- The following different naming schemes for network interfaces are now supported by udev natively: 1. Names incorporating Firmware/BIOS provided index numbers for on-board devices (example: eno1) 2. Names incorporating Firmware/BIOS provided PCI Express hotplug slot index numbers (example: ens1) 3. Names incorporating physical/geographical location of the connector of the hardware (example: enp2s0) 4. Names incorporating the interfaces's MAC address (example: enx78e7d1ea46da) 5. Classic, unpredictable kernel-native ethX naming (example: eth0) --- It looks like my B75M-ITX currently uses option 3, while I want it to use option 1, like all my other machines do. So according to the documentation, interfaces called enoX or ensX use index numbers provided by the firmware. However, I have no idea how or where this is defined. I would expect something to be in devicetree.cb, but I can't see anything seemingly related anywhere. So my question is: how does coreboot pass "index numbers for on-board devices" to the kernel / udev, and how can I define them properly on boards where this is not working the way it should?

Apply for GSoC

Dear all, My name is Xu LingXiao, i am a computer engineering student from University of Padua. I am interested in the topic "Port payloads to ARM, AArch64 or RISC-V", especially the RISC-V. The reason i want to attend this project is that i just received a risc-v board VisionFive2 from China(i am a Chinese student who study in Italy now), i want to port coreboot to my board. I plan to add payload to risc-v platform starting from qemu and then the real hardware. Now i have gone through the tourial, and here is serial output results(qemu-x86_64): [NOTE ] coreboot-4.19-701-g65c456227e-dirty Sun Mar 05 17:31:38 UTC 2023 x86_32 bootblock starting (log level: 7)...

Re: Deprecation of the Intel Quark SoC

Hi, My background is low level ARM and I want to get familiar with low level x86. I bought galileo v1 because it is cheap, small and handy x86 board. I have built coreboot code. It does not boot "out of the box". I had to add rmu.bin into coreboot.rom. With this logging on uart works. It seems SD/MMC controller also works. Now I'm struggling with: [INFO ] CBFS: Found 'fspm.bin' @0x31c40 size 0x2f000 in mcache @0x80004f84 [ERROR] CBFS ERROR: 'fspm.bin' allocation failure [EMERG] FSPM not available or failed to load!

Hello all. I'm Karim Taha, my nickname on the irc channel is Kimo. I'm a senior computer engineering student at Cairo University. I'm interested in the "Fully support building coreboot with the Clang compiler" project. I was able to build and test the project with the default options listed in the document tutorial, and currently I'm working on one issue of the small project section.

Unable to get S3 resume to work on new port
by Kevin Keijzer 01 Mar '23

01 Mar '23

Hello, I'm working on a port for a new board; the ASRock B75M-ITX. A friend of mine did the initial porting [1] based on the existing B75 Pro3-M and autoport. I then took over the board as I intend to build an HTPC around it. Everything works fine, with the exception of resuming from S3. The board goes to sleep fine, but when I resume it, I'm greeted with the payload. (As this board does not have a serial port, I don't have an easy way to get logs, but everything looks like it just does a cold boot because DRAM is reset.) Then I found out that on the ASRock B75 Pro3-M port, which has been in coreboot since 2017, S3 resume also does not work [2]. It is suggested there to find the proper DRAM_RESET_GATE_GPIO, so I tried that. I've compiled and flashed roms with DRAM_RESET_GATE_GPIO set in Kconfig from 0 to 75, but in all cases the board just reboots instead of resumes. So I'm not too sure what to try next. Does anyone have any suggestions? [1] https://review.coreboot.org/c/coreboot/+/73097 [2] https://review.coreboot.org/c/coreboot/+/20227 -- With kind regards, Kevin Keijzer
