FOSDEM Hardware Enablement Devroom
by Paul Kocialkowski
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!

Re: [coreboot] Server systems shipped with coreboot
by Piotr Kubaj
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.

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.
I haven't really heard anything referred to as "LPAR" on these newer
POWER8/POWER9 machines outside of legacy documents.

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

[off topic] Opteron CPU missing chips on the bottom

I purchased a used g34 opteron off of fleabay (sold as working with no
mention of this) and I noticed that it is missing some of the bits on
the bottom and that most of them are crooked, I haven't tried it in my
system yet and I am wondering should return it? or if there isn't any
much risk of it damaging my (expensive kgpe-d16) motherboard and I
should see if it works?
I got it for half the usual price....guess I should have asked for photos.
I noticed many CPU's sold on ebay have this issue (in those cases they
mentioned it) but I can't understand how it happens, for instance I
noticed a 6386 for sale where they mentioned that it was missing a few
and because of that it doesn't work in a dual socket configuration.
