Re: [coreboot] On Intel Boot Guard
by Alexander Couzens
Hi Iru,
we aren't still sure which boards use Intel Boot Guard and which doesn't use it. But we expect most board use it,
because it's "recommended" by intel - as we dont recommend it.
Also there isn't yet a test script for Intel Boot Guard.
Can you post a link to that forum post?
I would like to look into a x240 flash image. If you have such board it would be nice
if you can send me a copy of the flash image via private mail.
Cheers,
lynxis

coreboot ported to the ASUS KGPE-D16 (Libreboot: blobless, fully functional!)
by Timothy Pearson
All,
I have successfully ported coreboot to the relatively modern ASUS
KGPE-D16 server board (dual AMD socket G34, 16 DDR3 DIMMs,
https://www.asus.com/us/Commercial_Servers_Workstations/KGPED16/)! This
port uses native Family 10h initialization (_not_ AGESA or CIMX).
The Libreboot folks will be interested to know that this board can run
blob-free and still retain full functionality!
Port specifications:
CPU: Dual AMD G34 Magny-Cours (Family 10h)
RAM: 16 DDR3 DIMM slots with ECC support (tested with x4 4G DDR3-1333
unbuffered DIMMs)
Peripherals:
PCIe slots: all functional
PCI slot: functional
RS-232: functional
PS/2: expected to function, not tested (on SuperIO)
ASpeed VGA device: functional (text mode, see below)
IEEE1394: functional
On-board USB: functional
On-board NICs: functional
ASUS PIKE SAS controller: functional
PCIe ROMs: functional
Power management:
DDR3 voltage set: functional
ACPI/APIC: functional
Suspend/resume: broken
Other:
cbmem console: partial support (log truncated)
cbmem timestamps: functional
nvram: functional
BIOS recovery jumper: functional
ASpeed VGA:
The ASpeed VGA device initialises in text mode via its (new) coreboot
driver, however this initialisation is incomplete, leading to distorted
but quite usable VGA output. When Linux boots and engages the graphical
framebuffer all distortion disappears.
This port was not trivial. Almost every device used was broken and
required debugging/repair, with the notable exception of the SuperIO
chip. The AMD DDR3 controller was severely broken to the point where
large rewrites were needed in order to bring it in line with the BKDG.
Even after the various component drivers were repaired
Due to the labor-intensive nature of the port and the extensive changes
throughout the entire source tree, it is not economically feasible to
merge this port upstream at this time (I estimate upward of 30
independent patches would be required just to get the board booting!).
Raptor Engineering will, however, be continuing to maintain this port
internally, and I am currently looking into adding native Family 15h
support on top of this internal tree. Additionally, while it was not a
priority for the initial port, I will be attempting to enable
suspend/resume functionality as I have time.
If there is sufficient interest from the community in adding this board
to coreboot I would consider merging the changes in exchange for a
one-time contract payment in the vicinity of $35,000 USD. When
considering this offer please bear in mind that this is a fully
functional blobless board with a wide range of peripherals and expansion
options available, and that once these large changes are merged I will
continue to enhance coreboot functionality as before (e.g. with the
KFSN4-DRE and the T400). I would also be willing to add this board to
the test stand as the only fully supported 4-way Opteron board (socket
G34 Magny-Cours CPUs contain two separate CPUs in one package, making
this 2-socket board a 4-way system from a HyperTransport perspective).
Please let me know if you have any questions!

Looks like a false positive. ctx-phdr only gets passed on if nelements
is 1, in which we know that phdr was set.

Ultra-short post-mortem: out of three top BSDs only FreeBSD stable was
able to handle all hardware from very beginning, OpenBSD decided to
not work with media layer of 82577 as well as NetBSD, though OpenBSD
reported no driver issues. Hopefully I`ll have enough time to figure
out and patch the difference.

as already discussed in #coreboot(a)irc.freenode.net, there are two

Native graphics initialization unfortunately only exists for the models

Power on via USB, WoL from S5 on Panther (Haswell/Lynxpoint)
by Matt DeVillier
Greetings again!
As a corollary / follow-up to my previous inquiry on automatic power-on
when AC power applied, I'm now trying to
get Panther (Asus ChromeBox - Haswell/Lynxpoint) to power on from S5 via
a connected USB device (keyboard, mouse, IR remote) and via ethernet /
wake-on-lan-- all of which currently work for S3, but not S5.
Initial testing indicates that the USB ports are not getting put in the
D3/hot state, as the IR receiver doesn't blink to indicate button
presses as it does in S3. Looking at the panther/lynxpoint code, the
only places I found that the USB ports were enabled under S3 but not S5
were in panther/acpi_tables.c and lynxpoint/acpi/usb.asl. I modified
both files to enable USB under S5, with no apparent change.
For WoL, I couldn't find anything that explicitly enabled/disabled it.
I did try setting the WoL enable override bit in PMCON_3, but no
apparent change.
Any/all suggestions are appreciated. I did skim the 4th-Gen Core Family
PLatform I/O datasheet, but nothing jumped out at me there (other than
the WoL override I tried above)
thanks,
Matt
