Firmware Error (ACPI): Failure looking up [\_SB.PCI0.LPCB.HEC.ECAV], AE_NOT_FOUND

2018-07-13 Thread O. Hartmann 
Hello.

The target host is a

Fujitsu Esprimo Q956
Firmware V5.0.0.11 R1.26.0 for A3413-A1x
Date 05/25/2018
BIOS Revision 1.26

FreeBSD 11.2-RELEASE and 12-CURRENT (ISO Image from 9th July 2018, r336134) are
spamming the console with an annoying error:

Jul 13 10:00:32  kernel: Firmware Error (ACPI): Failure looking up

looking up [\_SB.PCI0.LPCB.HEC.ECAV], AE_NOT_FOUND (20171214/psargs-503)

The error is repeated endless.

Can this be fixed?

Thanks in advance and kind regards,

Oliver

IASL complains about he same error in two different UEFI firmwares

2014-09-23 Thread O. Hartmann 

Trying to fix an GPU issue on a laptop, I followed the steps as described in 
handbook,
chapter 12.17, debugging ASL/AML code.

I dumped on two different systems the ASL via

acpidump -dt as described and tried to recompile the result via iasl.


The outcome is a bit disturbing. IASL complains about the very same errors on 
two
diffrent systems.I'll show only one here, since the code block is identical.

Support for Lenovo acpi_video and nVidia GT740M Optimus video adaptor

2014-09-23 Thread O. Hartmann 

I have a Lenovo ThinkPad E540 which has the following CPU:

This laptop has a integrated HD4600 iGPU (Haswell CPU) as well as a nVidia GT 
740M GPU,
which is supposed to be with Optimus technology. I will refer to this issue 
later in this
post.

ACPI_VIDEO/ACPI_IBM:

loading both of these ACPI kernel modules seem not to provide any 
fiunctionality as
expected. The laptop runs with 100% brightness of the LCD and consumes the 
battery very
quickly. Trying 
#
#   Display
#
hw.acpi.video.lcd0.fullpower=75
hw.acpi.video.lcd1.fullpower=75
hw.acpi.video.lcd0.econony=50
hw.acpi.video.lcd1.econony=50
hw.acpi.video.lcd0.brigthness=75
hw.acpi.video.lcd1.brigthness=75

in /etc/sysctl remains without effect. I presume this is due to the laptop is 
neither
supported by the acpi_ibm.ko nor acpi_video.ko modules either?

Is there a way to manipulate the LCD brightnes? The Firmware Lenovo provides 
doesn't
allow without operating system running the change of the brightness or muting 
the
speakers with FN + FXX key, as it is provided by many other EFI/UEFI firmwares.


iGPU/GPU/Optimus:


Another serious issue is the built-in video adaptor. In UEFI, I have the 
opportunity of
selecting either "integrated" or "nVidia Optimus". Selecting "integrated" is 
supposed to
utilize the built in iGPU HD4600 - which is since Haswell's dawn unsupported in 
FreeBSD.
So, for some reasons along with my work, I'd like to have the dedicated GPU 
anyway, the
nVidia GT 740M.
And here is the culprit.

First, I do not know whether this device is a hybrid or real discrete GPU with 
the
ability of sharing, what nVidia calls Optimus.
Starting X11 with any of the nVidia provided BLOBs (xf86-video-nv doesn't 
support modern
GPUs like that and FreeBSD doesn't have, in contrary to many Linux 
distributions, modern
xf86-video-nouveau: the driver is simply extinct from the ports) with 340.24, 
340.32 and
343.13 gives a blank vt() console screen with a carrett in the uppermost 
lefthand corner.

Checking the the Xorg.log I realize, that the driver recognizes the existence 
of the GPU,
but it doesn't reveal any(!) display sockets, not even the built-in LCD. 
Whenever the
nvidia driver tries to access the video hardware, I see this messages popping 
up on the
console, indicating that there is something wrong, I presume:
