[coreboot] Re: Status of Supermicro X11 series?

[Christian Walter]

HI Stephane,

currently following x11 Supermicro boards are supported:

* x11ssh-tf
* x11ssm-f

The board status list is not always update and not very convenient to
update.

Let me know if you need to know more.

Chris

[coreboot] Re: Please solve this ACPI dilemma

[Paul Menzel]

Dear Keith,


Am 25.05.20 um 02:05 schrieb Keith Hui:

I am attempting to build SCMI [1] support for the DSDT for asus/p3b-f
to get around a PCI<->ACPI resource conflict that renders the whole
SMBus and the hardware monitor inoperative. The board has ACPI AML
hooks that run before and after suspend and resume, so my plan is to
have Linux access the SMBus exclusively through ACPI, using the driver
i2c-scmi.

The spec calls for methods _SBI, _SBR, _SBW, _SBT, _SBA. I don't need
the last two for my purpose so I'll skip them. During build iasl warns
that they are unrecognized reserved methods and **our build process
treats all warning as errors** so my build broke.


I created a bug report for iasl [1].

What is the error number? Please look into `IGNORED_IASL_WARNINGS` in 
`Makefile.inc` how certain iasl warnings can be ignored.



The driver knows that some IBM bioses implementing the methods without
the leading underscores, but it only expects this on devices with an
_HID of "SMBUSIBM". If I use this _HID, iasl errors out: "_HID suffix
must be all hex digits (SIBM)", so I have to use SMB0001, for which
i2c-scmi would only look for the _SB? methods, that from what I can
see is the correct way. So either my build breaks, or I can expect a
build that is not going to work.


Please contact the Linux maintainers.


I cannot proceed unless I hack the build process (I send in a patch to
Makefile.inc to make an exception for p3b-f) to disregard iasl
warnings.


Ah, looks like you found my suggestion already.


And if I resolve the conflict by removing all ASL code for SMBus
access, I would have no working suspend, even S1.

What am I supposed to do?



Kind regards,

Paul

[coreboot] Status of Supermicro X11 series?

[Stéphane Delaunay via coreboot]

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==de=en=https%3A%2F%2Fwww.heise.de%2Fnewsticker%2Fmeldung%2FOffene-Coreboot-Firmware-fuer-Xeon-Serverboard-4490578.html

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!___
