Dear coreboot folks,
On the Lenovo T60 (with AMD/ATI graphics) the Linux kernel (4.9, 4.19,
5.3, 5.4) hangs after starting user space. As SeaBIOS, GRUB, payloads
and FreeDOS work, I tried to limit the number of CPUs, and booting Linux
with `nosmp` gave me a booting system. It worked with older coreboot
versions, so I think it’s a regression. I am able to reproduce this with
coreboot 4.11 and 4.11-422-g1a5c3bb7fa.
Is somebody else seeing this issue? Maybe on some i945 desktop board, so
it would be easier to bisect?
Kind regards,
Paul

Yes, if you meant x86 desktop "supported by coreboot master" -
regarding the CPUs ;-) Otherwise there is a supported-by-coreboot-4.11
M5A88-V motherboard with AM3+ (maybe can put FX-9590 there, if
coreboot supports and without frying it?) and KGPE-D16 with its' two
Opterons 6386 SE for a large desktop. Also, PDF [link 1] at page 12
says Carrizo is the "1st ARM Trustzone Capable Performance APU", that
means Kaveri and its' refresh Godavari (i.e. A10-7890K) doesn't have a
PSP. A88XM-E motherboard is FM2+ socket, so theoretically it could
support Godavari A10-7890K. However Balazs wrote that AGESA of Kaveri
is a blob (not good!) and there's uncertainty if could get it working
without getting this APU for trying.
As you see, there are CPUs more powerful than A10-6800K which don't
have a PSP crap but their coreboot master support is questionable. And
don't want to be without coreboot, since UEFI could have many holes
and stuff like Computrace which doesn't need to rely on ME/PSP to
function. So yes, A10-6800K seems to be the best at the moment. I got
A10-6700 only because its' quite hard to find a new A10-6800K for a
reasonable price and I read about bad overclockers who played too much
with core voltages and cores deteriorate, becoming unstable even at
stock speeds (so one needs to underclock then). A10-6700 is the most
powerful with a locked multiplier, so less attractive to overclockers
and may be safer to buy used.
GPUs: yes, RX590 is the most powerful GPU without PSP ! (not
considering NVidia at all because of their proprietary driver tricks
and hostility towards the opensource) . Although there is RX600 series
[link 2], they are hard to buy and lower performance. Unlike the
majority of people (who don't care about performance), I actually
hoped there would be another refresh of Polaris architecture - simply
because no PSP, but doesn't seem there would be more Polaris high end
GPUs at the moment.
As for the most powerful RX590, I suggest those which have 8400MHz
memory by default - i.e. Sapphire Nitro+ parts. For myself I got a
cute [link 3] SKU 11289-07-20G aka "Sapphire Nitro+ RX 590 8GB AMD
50th Anniversary Gold Edition" (golden shroud) for about 250 USD.
Aside from being an AMD fanboy collector's item, it's nearly identical
to 11289-01-20G aka "Special Edition" (blue shroud) - however, there
were multiple hardware revisions of a Special Edition card (could be
distinguished by looking at their advanced P/N product number also
printed), while this Gold Edition came much later and with it I think
you're guaranteed to get the latest hardware revision. Now they are
sold out at many countries, but if you're lucky you could find some -
although maybe for the really inflated prices like [link 4] - that's
~320, about 30% more than I paid.
If you know another RX590 which is more powerful out of the box,
please tell - maybe I'd get a second one! In example, here's a pretty
[link 5] PowerColor Red Devil RX 590 8GB, with a neat pentagram on
its' back plate ;-) But its' memory is 8000MHz by default.

Hello,
The headphone jack is documented as broken and i was wondering if someone could help following a few tests I carried out with two identical laptops, one running the stock bios and the other corebooted.
When unplugged the value is always value = 0x0 and when plugged the value changes to value = 0x80000000. When docked the value on the stock bios gets updated but not in coreboot. When using the headphone it gets updated but no sound is output.
STOCK BIOS - Headphone
sudo hda-verb /dev/snd/hwC1D0 0x15 GET_PIN_SENSE 0
nid = 0x15, verb = 0xf09, param = 0x0
value = 0x0 = Unplugged
sudo hda-verb /dev/snd/hwC1D0 0x15 GET_PIN_SENSE 0
nid = 0x15, verb = 0xf09, param = 0x0
value = 0x80000000 = Plugged
**Sound Works**
COREBOOT - Headphone
sudo hda-verb /dev/snd/hwC1D0 0x15 GET_PIN_SENSE 0
nid = 0x15, verb = 0xf09, param = 0x0
value = 0x0 = Unplugged
sudo hda-verb /dev/snd/hwC1D0 0x15 GET_PIN_SENSE 0
nid = 0x15, verb = 0xf09, param = 0x0
value = 0x80000000 = Plugged
**Sound does not work**
STOCK BIOS - Docked [Headphone jack on the dock]
sudo hda-verb /dev/snd/hwC1D0 0x16 GET_PIN_SENSE 0
nid = 0x16, verb = 0xf09, param = 0x0
value = 0x0 = Unplugged
sudo hda-verb /dev/snd/hwC1D0 0x16 GET_PIN_SENSE 0
nid = 0x16, verb = 0xf09, param = 0x0
value = 0x80000000 = Plugged
COREBOOT - Docked [Headphone jack on the dock]
sudo hda-verb /dev/snd/hwC1D0 0x16 GET_PIN_SENSE 0

hda-verb /dev/snd/hwC1D0 0x16 GET_PIN_SENSE 0
nid = 0x16, verb = 0xf09, param = 0x0
value = 0x0 = Plugged but not updated!!!
ONLY the MIC is detected and enabled
sudo hda-verb /dev/snd/hwC1D0 0x19 GET_PIN_SENSE 0
nid = 0x19, verb = 0xf09, param = 0x0
value = 0x0 = unplugged
sudo hda-verb /dev/snd/hwC1D0 0x19 GET_PIN_SENSE 0
nid = 0x19, verb = 0xf09, param = 0x0
value = 0x80000000 = Plugged and Updated!!!
When docked the mic is enabled by default but headphone is not detected. Strangely if i plug another headphone in the laptop headphone jack, the dock headphones start working!
Could it be that the file https://github.com/coreboot/coreboot/blob/master/src/mainboard/lenovo/t440p… is missing the info about the jack being a combo port just like in the t520 https://github.com/rockchip-linux/coreboot/blob/master/src/mainboard/lenovo…

As user land tools currently use /dev/mem to access coreboot tables and
CBMEM, provide a better way by using read-only sysfs attributes.
Unconditionally expose all tables and buffers making future changes in
coreboot possible without modifying a kernel driver.
Changes in v2:
- Add ABI documentation
- Add 0x prefix on hex values
- Remove wrong ioremap hint as found by CI
Changes in v3:
- Use BIN_ATTR_RO
Changes in v4:
- Use temporary memremap instead of persistent ioremap
- Constify a struct
- Get rid of unused headers
- Use dev_{get|set}_drvdata
- Use dev_groups to automatically handle attributes
- Updated file description
- Updated ABI documentation

Angel is also looking forward to Braswell support. He mentioned it as a
possible summer-of-code stretch goal (after Bay Trail support), IIRC.
But applications are not written yet (start tomorrow).

Alas, this is a pitfall for Braswell. The only part that matters for
libgfxinit (information about the display engine) is 100% scrubbed
away. If you look into the `Display` chapter, it only contains legacy
VGA registers and audio verbs, nothing about display at all. And if you
search for any of "hdmi", "lvds", "mipi", "dsi", or "lane" in the
`Register` chapter: nothing :-/
So for Braswell, the only public information source I know is the Linux
driver i915. It's the one exception btw. All other chips have a proper
`Display` chapter. Hence also the idea to add Bay Trail support first.
Even if it turns out to be much different, we could at least tell if
Brasswell is closer to Bay Trail or the newer Haswell/Apollo Lake
engine.

This may get a little longer... but I knew I'll have to write it down
eventually.
In Ada, the code is organized in so called `packages`. In the way they
are used in libgfxinit, one can simply see them as compilation units.
Each package has a specification (.ads) file with declarations and a
body (.adb) with code. Much like a header and a c file. Packages form
a hierarchy and the name of the file has to reflect the package name,
including its parents (stupid, imho).
Libgfxinit has two major mechanisms in place to support different
hardware generations:
1. Alternative implementations of packages. These are organized in
sub-directories (also because every alternative package body has
to have the same file name). For instance, we have different
implementations for the package `HW.GFX.GMA.Connectors` in g45/,
ironlake/, haswell_shared/ (the latter is shared with all newer
generations since Haswell).
Having alternative implementations of packages also means we can't
build one binary that supports all generations. Luckily, we don't
have to, so far :)
2. Configuration flags that are tested in shared code. Much like we
have `if (CONFIG(FOO_BAR))` in coreboot, we have `if Config.Foo_Bar
then` in libgfxinit.
All these flags are gathered in a single package `HW.GFX.GMA.Config`
which keeps conditions on specific hardware generations in a central
place. The file, `hw-gfx-gma-config.ads.template`, is pre-processed
with some sed-foo (see `common/Makefile.inc`). The comment from
`hw-gfx-gma-config.ads.template:99` on explains some of the rea-
soning.
How much code sharing makes sense depends on the similarity to other
hardware generations. I wouldn't be surprised if Bay Trail and Braswell
end up using the g45/ code (no PCH and probably pre DDI which was intro-
duced with Haswell), but I don't know that yet.
Some more about the central packages:
HW.GFX* (excluding HW.GFX.GMA*)
===============================
There's some vendor-agnostic code around. Mostly for DP training and
EDID interpretation.
HW.GFX.GMA
==========
This exposes the primary interface (procedure Update_Outputs())
and contains the overall control flow for setting up displays.
Update_Outputs() takes a list of configurations for each graphics
pipeline (up to three) and will try to set things up according to
the configuration.
Assuming a pipe is unconfigured, roughly the following steps are
performed (by procedure Enable_Output()):
* Optionally select a link configuration (e.g. for DP, how many lanes at
what rate).
* Allocate a PLL for the pixel/DP clock.
* Try to train the selected link configuration (if there is none, the
loops simply run once):
- Prepare output connectors (Pre_On)
- Enable the graphics pipeline (On)
- Finalize the output-connector configuration (Post_On)
This usually doesn't need changes for new hardware.
HW.GFX.GMA.Pipe_Setup* (formerly Display_Controller)
====================================================
At the heart of the display engine is the pipe setup. Here we configure
the framebuffer format (how to interpret bytes from DRAM), image pro-
cessing (e.g. scaling) and the `Transcoders` that turn the image into
a continuous stream of bits (including blank times) for a given pixel
clock. IOW, everything from the framebuffer to a modeline.
This was called `Display_Controller` earlier (probably for historical
Linux reasons) and is still inside `hw-gfx-gma.adb` (easy to fix, but
I didn't care to so far).
It's mostly configured by flags from the `Config` package. Configu-
ration of scalers is often implemented very differently, but most of
it didn't change much over the years.
HW.GFX.GMA.Connectors
=====================
The `Connectors` package dispatches the Pre_On() and Post_On() calls
(before and after configuring the graphics pipeline) to sub-packages
for the individual connector types.
This is a bit subtle. In a sense, `Connectors` reflect the outputs of
the CPU package. In the first generations with a PCH (Ironlake including
Sandy and Ivy Bridge) the CPU didn't have actual display outputs (like
VGA, LVDS, HDMI etc.) but only links to the PCH which contained the
final outputs. Later, the final outputs went back onto the CPU die. So
we have three very different versions of this package:
* g45/ outputs are in the GMCH (or CPU if one would add Bay Trail,
it shouldn't matter).
* ironlake/ FDI links in the CPU and (most) outputs in the PCH.
* haswell_shared/ newer outputs (DDI) in the CPU (no legacy interfaces
like VGA/LVDS, and HDMI/DP configuration changed since g45/).
If none of these match the hardware to be added, one would have to
write a new one.
HW.GFX.GMA.PLLs
===============
Usually there are some similarities but often changes between hardware
generations.
HW.GFX.GMA.Power_And_Clocks
===========================
This started with some setup for generation specific things that didn't
find another place. Newer generations have configurable clocks and can
turn individual parts of the display engine on and off. Older ones often
just have to report a pre-set Core Display Clock (CDClk).
To wrap it up, `Power_And_Clocks` and `PLLs` most often need changes for
new hardware. Followed by `Connectors` if these changed significantly,
but most often one can add some code controlled by `Config` flags here.
And, not to forget, all flags in the `Config` package need to be checked
how they should be set for the new hardware.

Can be fun but can also be exhausting ;) Depends much on how you can
cope with nagging compilers and related tools.

Hi everyone,
I'm looking for an option to configure my Intel IvyBridge CPU (enable /
disable Hyperthreading, TurboBoost, set configurable TDP level etc.)
using coreboot / nvramcui. My board is a Lenovo Thinkpad T430. So far,
"only virtualization" is configurable and can not be enabled / disabled
"in flight" but requires a rebuild of coreboot.
Is anyone currently working on something similar?
Is anything planned in that regard?
Kind regards

Hi,
I am using coreboot to boot Denverton cpu (CPU C3558) based board.
I can see that the cpu frequency is set to the correct value i.e. "2200 Mhz" under the coreboot logs.
.
"
CPU #3 initialized
bsp_do_flight_plan done after 146 msecs.
cpu: frequency set to 2200
"
Later when I check the frequency reading under linux (kernel version 4.19) , It comes out as 800 Mz:
model name : Intel(R) Atom(TM) CPU C3558 @ 2.20GHz
stepping : 1
microcode : 0x24
cpu MHz : 800.000
When I reprogram the board with BIOS, the cpu frequency gets reflected correctly (i.e. 2200 MHz) with the same kernel image.
I have also tried out the different Grub command line options like disabling the pstate, and idle state e.t.c, but the end result remains same.
Can anyone please provide me some suggestions. Is there is any cpu specific settings which needs to enabled under coreboot or with Intel-FSP ?
Thanks,
Nitin.
Hi all,
I just wanted to ask about the current status of the Supermicro X11-series of boards.
I read on a German magazine that it should be supported by joint efforts of 9elements and Mullvad. Link (auto-translated):
https://translate.google.com/translate?hl=&sl=de&tl=en&u=https%3A%2F%2Fwww.…
Apparently there was a presentation planned at the OSFC 2019, but I can't find anything on it and the boards-list still shows them as status "Unknown", which seems odd.
Does somebody have any infos on the current development with these boards?
Kind regards!
Hi all,

Machine: Lenovo X1 Carbon 1st Gen (2012, no Boot Guard)
Flashing tool: CH341A USB programmer + Debian Linux
I am trying to replace the OEM firmware with Coreboot 4.12 and then install
OpenBSD into the machine and set it up as an internet facing firewall. I
ran me_cleaner against the dumped SPI image already.
1. Can anyone please tell let me know how can I achieve the captioned
objectives? I looked into ifdtool & uefitool but found nothing related to
my goal. I also tried the "lock ME/TXE" option during make menuconfig but
Intel chipsec is still reporting the captioned bits not set on my
Coreboot-flashed X1 Carbon
2. Is it correct to say that once the PR0-5 bits are set and Coreboot
flashed into the machine, the values of the PR registers will be configured
accordingly after machine boot up (when OS is having control)?
Thank you very much for looking into my questions!
