Coreboot doesn't POST on ASUS KCMA-D8

      I have a KCMA-D8 motherboard with two Opteron 4226s, and 6x4GB (24GB) Hynix
HMT151R7BFR4C-H9 RAM sticks. All my attempts of getting Coreboot to POST with this board
so far haven't worked. I'm compiling Coreboot from Git (master branch), and can
build it without issue. A pre-built Libreboot ROM (20160907) POSTs and boots fine.

For Coreboot's config, I've tried including/excluding CPU microcode updates, along
with some less important-sounding options. For hardware, I've tried unplugging
everything external (KB/mouse), my GPU (RX 580), and only had a single RAM stick in (slot
A1). I've also tried a single CPU being powered (kept the 2nd CPU in but only had a
single 4-pin CPU going to the 1st CPU).

Can anyone else confirm Git builds of Coreboot booting on this board, or provide any tips
as to anything I could be missing?

I see this issue https://ticket.coreboot.org/issues/151 but there's a board status
months after that that looks like it boots:

Hi all,

I ran into the same issue, and I'd like to find the coreboot commit
which introduces these problems.

My RAM is: Hynix HMT31GR7CFR4A-PB (8 GB 2Rx4 PC3L-12800R). I just now
realized that it's low power DIMMs, but it boots fine with libreboot,
so that shouldn't be a problem.
A have two DIMMs installed in the slots A2 and B2 (according to the
manual), with one Opteron 4332HE installed.

I managed to build an older coreboot revision around the time of the
last libreboot release (which boots fine for me), but unfortunately it
doesn't output anything on VGA / serial.

I might make a few more tries tonight, or in some weeks when I have
access to the machine again.

For the record I attached the serial log when booting with current
master; apparently there's a failure during DIMM training...


Regards,

Merlin

      Hi, thanks for the info!

For the particular POST issue, I limited it down to the RAM. I replaced
it with some other RAM and it POSTs fine. I don't know if I mentioned
it in the initial post, but Libreboot's 2016 stable build booted fine
with that same RAM, as did the ASUS vendor BIOS; Coreboot just didn't
like it.

  I assume you want to play games as you have a RX580
I ended up buying two 4386's and have those now; I don't do too much
gaming nowadays, but still have the RX 580 around for 4K@60Hz over
HDMI.

I don't include microcode updates just for an easier build (I do a
shallow clone of CB's repo but it doesn't seem to pull in 3rd-party CPU
stuff), but my distro handles microcode hotpatching at boot.

  There are only a few games that are capable of using
more than 8
cores
but the advantage of a second CPU is that you can do other stuff at the
same time without noticing as long as you use cpu pinning/isolcpus for
your vm gaming.

I'll have to figure out core pinning. The only game I play nowadays
(old school Runescape) uses Java, but really prefers single-threaded
performance.

  For power consumption you should have nohz=on setting
on your kernel
command line otherwise the modules will never enter CC6,
pcie_aspm=force
is also another good one to have so is tweaking your CMOS settings for
power saving like enabling sata alpm and disabling 1394.

Thanks for those kernel options as well!

  SAS card
I've heard about the SAS card, but I don't believe I particularly need
it for now.

  ASMB4 or ASMB5 module
I have some remote KVM chip thing that came on the motherboard, but I
can't quite figure out OpenBMC. Looks like it needs compiled from
source, but I wonder if there's a pre-compiled binary somewhere I can
just flash to give it a try.

  Btw have you heard of OpenPOWER?
I've heard of OpenPOWER, but their motherboard and CPU prices are way
out of my price range unfortunately.

  Maybe try cleaning the contacts if they look dirty?
I returned the RAM already, but didn't try cleaning the contacts.

  There is your issue or at least one of them - you need
dual 8pin EPS
cables - one per CPU

I have two actual 8-pin connectors; I unplugged one just to see if that
would change anything but nothing changed.

  It should I tested it a few months back although I use
v4.6 on mine
due to some power consumption regressions in master.

Now that I have compatible RAM, Coreboot master works fine for me.

FYI I would caution against trying to use the PIKE slot on KCMA-D8, I
tried using a PIKE2008 in it but could never get it to enumerate
properly i.e. the card is detected by coreboot and Linux but it
doesn't get any addresses assigned to it by the kernel rendering it
unusable.

I use this card in a KGPE-D16 now so it's not the card that's broken,
could be that something was wrong with my D8. Regardless I tried to
bisect this back to when D8 support was initially introduced in
coreboot and as far as I could tell the PIKE slot never worked on D8.

@Taiidan have you ever actually seen (or head of) the PIKE slot
working on D8?

You probably won't get decent gaming performance with these I would swap
them out for 4284's or 4240s I assume you want bulldozer cpus so you can
use libreboot ie: not needing microcode updates although I advise them
for spectre.

With 4284 (or the slightly faster but microcode updates mandatory 4386)
or what not and a RX580 8GB you should be able to max out new games
while gaming in a VM - let me know if you need help with that.

There are only a few games that are capable of using more than 8 cores
but the advantage of a second CPU is that you can do other stuff at the
same time without noticing as long as you use cpu pinning/isolcpus for
your vm gaming.

Another performance tweak is to combine half the modules of two CPU's to
obtain Turbo 2 performance on your gaming VM so with dual 4284's for
example you would get 3.7ghz rather than 3.3ghz or 3.7ghz on the first 4
cores and 3.3ghz on the last 4 cores in case you wish to do something
else on the second CPU while you are gaming.

For power consumption you should have nohz=on setting on your kernel

Btw have you heard of OpenPOWER? The raptor blackbird/talos 2? It is the

is the the only reason to get a D8/D16 now that the blackbird is price

is ok.

Anyway what does the console logs say? If you don't have one get a null

[Sean Lynn Rhone]

      After some more compiles, I finally figured it out; it's the RAM.

The Hynix HMT151R7BFR4C-H9 sticks I have work fine in Libreboot, but
didn't work with any Coreboot release I tried (tagged 4.6, the last
build reported in board status for the KCMA-D8, and master). Tossed in
the old RAM I had lying around, and Coreboot boots fine even on master.

I wasn't expecting the RAM to be an issue since it worked in Libreboot
though. As I understand, RAM compatiblity varies between the
stock/proprietary BIOS and Libreboot/Coreboot, but I didn't think the
compatibility would also vary between Libreboot and Coreboot.

Hi,

It sounds like you may be having a similar issue to the one I had with the KGPE-D16 a
month or so ago. Currently coreboot 4.8 doesn't boot for me if "Use CMOS for
configuration values" is selected when coreboot is built. Coreboot 4.6 doesn't
have this issue, so it may be worth a try building that version and seeing if you have
better luck.

Kind regards,

Pete

      Please Try without GPU, AMD GPUs where often buggy for me in the Past.
