Hi! On 30.06.2013 19:28, Christian Weinz wrote: > Maybe I didn't include the VGA option in the make menuconfig process. > How can I solve this problem? You need to add the VGA Option ROM (VGA BIOS -> Add VGA BIOS image). I've extracted it from the UEFI, but you also could use these: http://www.coreboot.org/index.php?title=ASRock_E350M1&oldid=11114 at the end of the page or you also may be able to use the default AMD fam14 (Persimmon) vbios. You will need to agree to the click through: http://wwwd.amd.com/support/vbioslic.nsf/userverify?openform http://www.coreboot.org/AMD_DB-FT1_PERSIMMON It's a pity, that bios_extract didn't work for now. You could use the AMI Aptio EFI MMTool with wine: http://win-lite.de/benutzer/fernando/BIOS-Tools/AMI_Aptio_EFI_MMTool_v4.50.… You need to extract OntarioEFIVbios with PCI ID 1002,9802 as Option ROM.

ASUS KCMA-D8 workstation board port offer
by Timothy Pearson 20 Jan '17

20 Jan '17

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 All, After reviewing some of the comments on the ASUS KGPE-D16 being essentially too large of a system and too expensive for many people, and the fact that modern, blob-free systems are not really available in the mid-range arena, Raptor Engineering would like to offer to create a native initalization blob-free port for the ASUS KCMA-D8, which is essentially the KGPE-D16's ATX-compatible "little brother". We would be asking $15,000 for the port, including upstreaming to the master coreboot tree. We already have extensive experience with these Family 10h/15h boards, and would be able to create a port of similar quality to the existing KGPE-D16 source in terms of both code quality and overall functionality. If this is something you might be interested in please let me know. We are able to accept multiple payments from various sources for the same project (within limits), so if this is something your local Linux groups or similar might be interested in we should be able to keep the cost on any one individual or organization to a reasonable level.

Re: [coreboot] F2A-85M: Different VGA BIOS needed after CPU Upgrade?

Hi John, > It sounds to me as though the PCI id's of the graphics card for the > upgraded CPU may be different (I could be totally wrong about that, so I > defer to others on the list if I'm barking up the wrong tree) and your > coreboot image may need to be updated accordingly. Of course, it could > also be the video BIOS that's the problem as you've suggested. Thank you for the hint. I inspected that, but the PCI-IDs actually look the same: 00:01.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Trinity [Radeon HD 7480D] [1002:9993] (A4-5300) and 00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Richland [Radeon HD 8670D] (prog-if 00 [VGA controller]) (A10-6700) Looks like the VGA BIOS is really different: # diff vgabios_a4-5300.bin vgabios_a10_6700.bin Binary files vgabios_a4-5300.bin and vgabios_a10_6700.bin differ Guess I will have to to "update" the VGA BIOS then.

The board had Coreboot installed before with the VGA BIOS extracted from the A4-5300. However, I did not get any video output when trying to boot after the upgrade, so I replaced the flash chip with a backup with the vendor BIOS that works. > > > > Is it likely that the A10-6700 needs a different VGA BIOS or does this this rather look like a different issue?

Linux 4.7 kernel payload with CoreBoot 4.4
by Trammell Hudson 12 Dec '16

12 Dec '16

The Linux 4.7 kernel payload crashes early in the boot process with CoreBoot 4.4. I traced it to these instructions that are finding a safe spot to decompress the rest of the kernel and patched around it with a hard coded location: diff -u --recursive /home/hudson/build/clean/linux-4.7/arch/x86/boot/compressed/head_64.S ./linux-4.7/arch/x86/boot/compressed/head_64.S --- /home/hudson/build/clean/linux-4.7/arch/x86/boot/compressed/head_64.S 2016-07-24 15:23:50.000000000 -0400 +++ ./linux-4.7/arch/x86/boot/compressed/head_64.S 2016-08-05 12:07:11.399854225 -0400 @@ -340,9 +357,15 @@ 1: /* Target address to relocate to for decompression */ +#if 0 movl BP_init_size(%rsi), %ebx subl $_end, %ebx addq %rbp, %rbx +#else + // coreboot does not populate the init_size boot param? + // fake it with a hard coded value + movl $0x97b000, %ebx +#endif /* Set up the stack */ leaq boot_stack_end(%rbx), %rsp It seems that the Linux kernel bzImage is supposed to set this value, rather than coreboot, so my comment is likely incorrect. Dumping linux-4.7/arch/x86/boot/header.o, it looks like init_siez is supposed to be 0xcf5000, so I wonder if %rsi is pointing to the wrong location. In 4.6.4 the computed address was hardcoded: movl $LOAD_PHYSICAL_ADDR, %ebx /* Target address to relocate to for decompression */ addl $z_extract_offset, %ebx 3e: bb 00 00 00 01 mov $0x1000000,%ebx 43: 81 c3 00 00 00 00 add $0x0,%ebx -- Trammell

PCI passthrough on ASUS KGPE-D16
by opteron＠keemail.me 26 Nov '16

26 Nov '16

Hi, would it be possible to passthrough a graphics card to a virtual machine while using Coreboot/Libreboot? The libreboot website says that the motherboard offers full IOMMU-support when using a CPU from the Opteron 6200/6300 series. https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF https://libreboot.org/docs/hcl/kgpe-d16.html

[RFC] Finding a conference call solution for the CCC
by Paul Menzel 04 Nov '16

04 Nov '16

Dear coreboot folks, At the last coreboot community meeting (CCC) [1][2], some participants couldn’t here what other participants were saying with the current conference call solution Discord [3]. As this greatly reduces the productivity, the conclusion was to find a different solution, as this problem has been present since the beginning and Discord doesn’t seem to be able to fix this. So either somebody gets in contact with Discord, and they promise to work on a solution for the next meeting, or we need to find a different solution. The requirements are. 1. Working conference call (audio) functionality 2. No registration necessary 3. Clients for all operating systems (packages at best in distribution archive), or at least a Web client that runs with Mozilla Firefox (ESR and last version), and Google Chromium (last version). Chris(?) offered to set up a Mumble [4] server. Clients for all operating systems are supposed to be available. Also Tox was mentioned [5], which doesn’t feature a Web client, as far as I can see. So if you know of a solution, please tell us, so that technical problems won’t spoil the fun of the CCCs. Thanks, Paul [1] https://www.coreboot.org/Coreboot_community_meeting [2] https://coreboot-meeting.pads.ccc.de/CommunityMeetingTopics?

Fund a TALOS Secure Workstation as coreboot build system
by Paul Menzel 04 Nov '16

04 Nov '16

Dear coreboot folks, At the last coreboot community meeting (CCC) [1][2] the TALOS Secure Workstation was brought up, and most people said, they won’t be able to afford the base system. Martin said it’d be great to have one system as a coreboot build system, and suggested that the coreboot community together funds a workstation. What do you think? Thanks, Paul PS: Please spread the word of the crowdfunding to your friends, and coworkers, and support it, so that it’ll be a success.

Petitboot based bootloader
by Arthur Heymans 01 Nov '16

01 Nov '16

Hi I have been working on building a Petitboot, a kexec bootloader, [0] based Linux payload using the Buildroot build system to produce a nice bzImage that contains both linux and the initrd. It is inspired by the Raptor Enginering HOWTO [0] and is based on op-build [1], the tool for building OpenPOWER firmware, which also uses Buildroot and Petitboot. One of the advantages of Petitboot is that it is fairly simple and intuitive to use and does not require complex configuration like grub does, while still providing a large range of hardware support since it uses linux at its core. A disadvantage is that a Linux + initrd payload takes up quite a bit of space. A fairly stripped down kernel + initrd takes up ~6.9M in the current Buildroot + Linux configuration I have. So a large flash chip or replacing the flash with a larger one is recommended. Coreboot can directly use this Linux payload or first load SeaBIOS which can then chainload the Linux payload. It is still very much a WIP and is currently aimed at Intel hardware, but with a kernel configuration tuned to your target it should work fine. The repo + initial documentation: https://github.com/ArthurHeymans/petitboot_for_coreboot [0] Petitboot: A kexec based bootloader, https://www.kernel.org/pub/linux/kernel/people/geoff/petitboot/petitboot.ht… [1] Creating firmware images with petitboot and coreboot https://secure.raptorengineering.com/content/kb/1.html [2] OpenPower Firmware Build Environment https://github.com/open-power/op-build Kind Regards -- Arthur Heymans
