https://review.coreboot.org/21774 In case anyone else didn't notice - It is a sandy/ivy system with IOMMU. This is great and should help get coreboot in to the corporate user world.

FOSDEM Hardware Enablement Devroom
by Paul Kocialkowski 04 Dec '18

04 Dec '18

A Hardware Enablement devroom will be taking place at FOSDEM this year, on Sunday 10 December 2017. This newly-created devroom is the result of 3 proposals that were merged together. It is co-organized by several individuals. The devroom covers all aspects related to hardware enablement and support with free software, including aspects related to boot software, firmwares, drivers and userspace tools and adaptation. Proposals for talks related to these topics are welcome and can be submitted until Sunday 26 November 2017 via the pentabarf interface. Short talks are encouraged over longer ones in order to cover a wide range of topics. The announcement for the devroom, that contains all the useful information, was published at: https://lists.fosdem.org/pipermail/fosdem/2017-October/002649.html Cheers and see you at FOSDEM! -- Paul Kocialkowski, developer of free digital technology and hardware support Website: https://www.paulk.fr/ Coding blog: https://code.paulk.fr/ Git repositories: https://git.paulk.fr/ https://git.code.paulk.fr/

Re: [coreboot] Server systems shipped with coreboot

There's no "pure coreboot" systems. You need some payload. Also, while Talos is truly awesome, the OP asked about coreboot specifically and Talos doesn't run coreboot :) At the moment, the best coreboot-supported server motherboard is ASUS KGPE-D16. You can also get libre BMC with OpenBMC port for it. If you just want a libre motherboard, Talos is the best you can get.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 4 cores, SMT4. There's an 8-core available for $190 more, and AFAIK there are plans to start offering an 18-core server chip very shortly. These are the OpenPOWER machines, so there is hardware virtualization support (including I/O passthrough) that works well with kvm and QEMU.

Microcode updates for slightly older intel CPU's re: meltdown/spectre
by Taiidan＠gmx.com 21 Mar '18

21 Mar '18

I am curious of any intel insiders know if there will be microcode updates released for older intel CPU's (ex: sandy/ivybridge) and failing that, what can be done in regards to securing them from meltdown/spectre. I believe this is a relevant coreboot topic considering how many coreboot boards have these and older CPU's....without a fix there will be only one coreboot compatible laptop with open source hardware initiation that is remotely secure (lenovo g505s as has a pre-PSP AMD CPU) and theoretically owner controllable (as the previous C2D/C2Q's such as the X200 are now permanently insecure without intervention from intel apparently) At this point even a massive performance loss is better than having to throw out so much now-useless hardware.

[PATCH 0/5] coreboot table bus and framebuffer driver
by Samuel Holland 14 Mar '18

14 Mar '18

On many systems, coreboot[1] firmware can initialize graphics hardware and set up a high-resolution linear framebuffer. It exports information about this framebuffer, along with various other information, in a table discoverable via ACPI or a device tree. coreboot also supports booting Linux directly from flash as a "payload". Projects such as Heads[2], u-root[3], and petitboot[4] provide a minimal userland that can then be used to chainload (via kexec) into a full Linux system loaded from disk or over the network. Fitting even a minimal Linux system on an SPI flash chip is challenging. Reusing the framebuffer setup from coreboot provides an enormous benefit to these projects by allowing them to omit full graphics drivers from their kernel builds. It also speeds up boot times by avoiding duplicated effort, and because coreboot's graphics initialization is often much faster than the Linux driver. Patch 1 of this series expands coreboot table support into an enumerable bus that devices can hang off of. Patches 2-3 convert the existing drivers to use the new bus structure instead of ad-hoc platform devices, and patch 4 removes the old coreboot_table_find function. Finally, patch 5 adds a new driver for the coreboot-initialized framebuffer. It improves on earlier work[5] by being architecture- independent and not needing to scan through low memory. This patchset has been tested on a Lenovo ThinkPad X220, and earlier versions of these patches have been tested by various members of the coreboot community on other hardware.

I have a few Opterons which have this issue and it seems to pretty common. I assume that some "expert" put the CPU on a table before mounting it, and they move it one the table - can't imaging how people manage to chop off the chips otherwise. While some of these damaged CPUs seem to work just fine, I had several which do not recognize more than 1-2 pcs of memory and, thus, would not recommend buying one of these. Cheers, Daniel

Serial input / output with SeaBIOS 1.11.0
by Piotr Kubaj 15 Feb '18

15 Feb '18

Hi, I've upgraded my coreboot to tag 4.7. As a payload I use SeaBIOS. I want to use the new feature of serial communication from SeaBIOS. The issue I have is that there's only serial output (meaning I can see the SeaBIOS menu on serial), but pressing any key on keyboard via serial doesn't do anything - I can only control SeaBIOS via keyboard plugged directly to the board, not via serial. Does anyone have the same issue? I use AsRock E350M1 board. I didn't create a custum SeaBIOS config, I just use the default one. -- ________________________ / Accordion, n.: \ | | \ A bagpipe with pleats. / ------------------------ \ ^__^ \ (oo)\_______ (__)\ )\/\ ||----w | || ||
