Re: Run abuild only on sandybridge boards with MRC raminit. How?
by Keith Hui 03 Aug '23

03 Aug '23

Hi Martin, Thanks for your reply. My abuild version is 0.11.01 dated this February. I recently put out a patch (CB:76775) to get abuild documentation back into the tree. I took a text capture of that version and incorporated it into the content. Eventually I was able to get that command line to do what I want (build only SNB boards), as is. I created coreboot-builds myself under main coreboot directory and mounted another filesystem there, at first a zram instance and then an ext4 image file on my external mechanical drive, so I don't wear down my SSD excessively. Build environment is Fedora 38. Bash version I haven't checked. My patch mentioned another earlier patch of mine on variant handling. Like I said at the time we either fix the handling or document the quirk. I documented the quirk. I also documented a real life case of ambiguity in the patch, which dovetails nicely into --skip_(un)set options I added documentation for. Two things we could look at.

Run abuild only on sandybridge boards with MRC raminit. How?
by Keith Hui 03 Aug '23

03 Aug '23

After 34 patches converting all sandybridge boards to Haswell-style SPD info, I now need to run abuild to see if I missed any, To save time, space, and possibly wear on my SSD I only want to run abuild on sandybridge boards (i.e. boards with NORTHBRIDGE_INTEL_SANDYBRIDGE Kconfig) and, for boards that don't force USE_NATIVE_RAMINIT, run it with that Kconfig off. I ran this from my mechanical USB drive: $ util/abuild/abuild --timeless --skip_unset NORTHBRIDGE_INTEL_SANDYBRIDGE -R /usr/src/coreboot And all boards get skipped. It seems right, until I saw these two known SNB boards getting skipped too, then I stopped the run. Building board INTEL_DQ67SW (using default config) Building INTEL_DQ67SW Creating config file for INTEL_DQ67SW... INTEL_DQ67SW (Skipping CONFIG_NORTHBRIDGE_INTEL_SANDYBRIDGE not set) INTEL_DQ67SW config created. config file: coreboot-builds/INTEL_DQ67SW/config.build has incorrect config value INTEL_DQ67SW does not have NORTHBRIDGE_INTEL_SANDYBRIDGE set. Skipping at user's request. Building board INTEL_EMERALDLAKE2 (using default config) Building INTEL_EMERALDLAKE2 Creating config file for INTEL_EMERALDLAKE2... INTEL_EMERALDLAKE2 (Skipping CONFIG_NORTHBRIDGE_INTEL_SANDYBRIDGE not set) INTEL_EMERALDLAKE2 config created. config file: coreboot-builds/INTEL_EMERALDLAKE2/config.build has incorrect config value INTEL_EMERALDLAKE2 does not have NORTHBRIDGE_INTEL_SANDYBRIDGE set. Skipping at user's request. Is what I did supposed to work? For the second item about USE_NATIVE_RAMINIT, do I really have to set a board config for each and every MRC raminit board and turn it off there?

Abandoning old patches
by coreboot org 02 Aug '23

02 Aug '23

Hello all, In preparation for the upcoming 4.21 release and the planned update from master to main, we are abandoning all patches that haven't been updated in the past year. This list can be seen via a gerrit search: repo:coreboot status:open before:2022-08-07 I've also documents of all the patches that would be abandoned as of today: - https://pads.ccc.de/TL72QP43Pg - https://docs.google.com/spreadsheets/d/1V8X63frTLGN4hvA2maJYp0zmipJqAXVG0nW… To prevent a patch from being abandoned, any change in gerrit will refresh the activity date and remove it from the list. Feel free to go through the list and refresh any patches which are still relevant. After the patches are abandoned, they can still be brought back and the review continued at any time. This is merely cleaning up the list of active patches. The list will be refreshed on Monday, August 7th, and any patches still on the list at that point will be moved to the abandoned state. -- Martin Roth

[coreboot - Feature #476] (New) Add option to convert coreboot-inited linear frame buffer to efifb directly
by Bill XIE 02 Aug '23

02 Aug '23

Issue #476 has been reported by Bill XIE. ---------------------------------------- Feature #476: Add option to convert coreboot-inited linear frame buffer to efifb directly https://ticket.coreboot.org/issues/476 * Author: Bill XIE * Status: New * Priority: Normal * Category: coreboot common code * Target version: none * Start date: 2023-03-30 * Affected OS: GNU/Linux ---------------------------------------- Currently, the linear frame buffer that coreboot initializes should be handled by Linux kernel with dedicated driver "simplefb", but most installer of GNU/Linux distributions only enables "efifb" support, which causes a GNU/Linux installer kexec-ed from a Linux payload running atop simplefb unable to output graphics. Currently, Grub payload could turn coreboot-initialized simplefb to efifb, which can be easily examined from the dmesg log of GNU/Linux booted from Grub payload running atop coreboot-inited linear frame buffer (simplefb). Chainloading a Linux payload with a minimal Grub payload only containing module "linux" and "cbfs" could make the Linux payload running atop efifb, of which GNU/Linux installers can make use, but the related code could be ported to coreboot to make things easier. -- You have received this notification because you have either subscribed to it, or are involved in it.

New Matrix channel #coreboot:matrix.org
by Nico Huber 31 Jul '23

31 Jul '23

Hi all, due to ongoing reliability issues with the matrix.org-to-libera.chat bridge, channel portalling is going to be disabled [1]. Hence there is a new Matrix channel #coreboot:matrix.org [2] that is bridged to the IRC channel on Libera. Hopefully, this will work a little better. AIUI, the old channel will become read-only on the Matrix network by August, 11th. So all Matrix users are encouraged to join the new channel. For direct IRC users, nothing changes. Best regards, Nico [1] https://libera.chat/news/matrix-deportalling [2] https://matrix.to/#/#coreboot:matrix.org

switch or router hardware with coreboot
by Carl-Daniel Hailfinger 28 Jul '23

28 Jul '23

Hi, is there any currently commercially available switch or router hardware (10Gbit/s or more) running coreboot and preferably also Linux? I'm currently trying to build a PoC network where all components have mostly FOSS firmware and operating systems. My Wifi access points and 1 Gbit/s switches are running U-Boot and OpenWrt, so on that tier I'm covered. OpenWrt is even running on very few select 10 Gbit/s switches, but there the bootloader seems to be U-Boot+blob. For routing, I'm currently using PCEngines APU2 with coreboot and Debian, but those are not really made to handle routing or even NAT at more than 1 Gbit/s. Once the PoC phase is done, I expect required routing/NAT/packet filtering bandwidth to exceed 5 Gbit/s and I'd like to use a coreboot based product for that. If necessary, I can add a few network cards to a general-purpose server, but a purpose-built device would be preferred. Suggestions? Comments? Thanks, Carl-Daniel

CPU with a faulty RAM controller? o_O AGESA debug info inside
by Mike Banon 28 Jul '23

28 Jul '23

Faulty CPUs are truly rare... But recently while building the A88XM-E coreboot test stand (more info at [1] "ProTip: buy a 5.25" fan controller while you still can" link below) ---> I got a used A10-6700 online for a dirt cheap price: the listing looked nice - a clear photo without any bent pins - but there was an intriguing note "one RAM slot doesn't work". So I thought: > That looks like a motherboard problem! Or something related to the seller's RAM sticks: either a faulty stick or a badly mismatching pair. Shouldn't happen on my spare well-tested A88XM-E with a known good RAM, especially with a beautiful coreboot replacing the crappy proprietary UEFI, so lets save a few bucks " However, I ran into the same problem: the board boots fine to OS but sees just one of two BLT8G3D1869DT1TX0 8GB RAM sticks, regardless if I use the XMP profile to run them at 1866MHz CL9 ( CPU_AMD_AGESA_OPENSOURCE_MEM_XMP_1 stuff which I created two years ago - [2] ) or keep them at turtle 1333Mhz CL9. Here are the most interesting AGESA events which happen while trying to initialize the RAM: *) WARNING Event: 04012100 Data: 0, 0, 0, 0 [0m ; AGESA.h tells: #define MEM_WARNING_CHANNEL_INTERLEAVING_NOT_ENABLED 0x04012100ul ///< Channel Interleaveing Requested, but could not be enabled *) WARNING Event: 04012200 Data: 0, 0, 0, 0 [0m ; AGESA.h tells: #define MEM_WARNING_BANK_INTERLEAVING_NOT_ENABLED 0x04012200ul ///< Bank Interleaveing Requested, but could not be enabled *) ERROR Event: 04010300 Data: 0, 0, 0, 0 [0m ; AGESA.h tells: #define MEM_ERROR_NO_DQS_POS_RD_WINDOW 0x04010300ul ///< No DQS Position window for RD DQS See the full AGESA log here - https://pastebin.com/FLWFk9SF . Please keep in mind that, if I replace this with another (bought later) A10-6700 - using the same A88XM-E / RAM / coreboot / OS - then everything works fine. So it's clearly a CPU problem, but may be possible to avoid from the firmware side... Do you think it's possible to workaround this problem (no matter how dirty the hack) from AGESA side and get this CPU working with both sticks? Is there anything I could try before giving up and making a DIY keychain or whatever? Any ideas?

[PATCH] firmware: coreboot: framebuffer: Allow building with simpledrm
by Alper Nebi Yasak 25 Jul '23

25 Jul '23

The coreboot framebuffer driver registers a "simple-framebuffer" device based on the information from the firmware, after checking that it's compatible with the formats listed in simplefb.h. It was added before simpledrm, and its Kconfig marked as dependent on the simplefb driver. The simpledrm driver can also handle "simple-framebuffer" devices and the coreboot framebuffer works fine with it on a 'Lick' Chromebook. Allow building the coreboot framebuffer driver with simpledrm as well.
