atheros wi-fi + intel VGA on corei5 postinstallation issue

Postby pansonic » 2017-02-21 00:50

Premise
Hello debian people,
this is my first post, so let's do some presentation: I'm a web developer but not a total geek. After more then 10 working life took me from writing articles for the web to building websites. I'd like make debian my main working platform, I think you clearly bet why. Alongside servers machines, some time ago I had a nice experience when debian (+ LXDE) give a new birth to an old compaq Presario from the year 2002 AD.
As I told you, I'm not a geek, but I don't have too much fear of terminal: it barks sometimes, but it never bitten.
Oh, as you can read I'm not a native English speaker, sorry for mistakes here and there :oops:

Technical Stuff

In a Human Readable terms, after an installation of debian 8.7.1 amd64 from official iso I noticed two main issues: wi-fi card and brightness/contrast/color control. I tried to solve by myself reading lots of documentation, winning some battles but loosing the war. I understand that could be related to non-free firmware, maybe involving kernel. So I tried again with a unofficial debian 8.7.1 release netinst with non-free firmware. Unfortunately the firmware I probably need it's not included.

to be more specific on the version in use
[ 0.000000] Linux version 3.16.0-4-amd64 (debian-kernel@lists.debian.org) (gcc version 4.8.4 (Debian 4.8.4-1) ) #1 SMP Debian 3.16.39-1 (2016-12-30)

In my first attempt I tried to install the ath10k firmware, cause I sorted out that could fit the wi-fi card. For those who can understand this (not me) I runned a very verbose lspci:

The rebirth of the compaq (see premise) came useful because at the time I bought a wi-fi usb adapter ready for linux, which I'm using instead of the built-in.
After installing the ath10k firmware from https://github.com/kvalo/ath10k-firmware by the "make" method, the system recognized the wi-fi card, but it was unstable, had waving signal and above all I noticed that the notebook never shoot down or stuck on reboot.

I tried a backport, but didn't solved.
I tried to update the kernel to solve the shootdown problem, but maybe I messed something and can't even boot.

I don't know if I should post another thread: let me know better guidelines to adjust the title (make it more useful for other users) and split the post. Anyway I think it's firmware-related but I can't find documentation that fits my case, or maybe I'm missing something.
I have problem with brightness control (this screen is hurting my eyes and wasting energy). The folder /sys/class/backlight is empty. I read it is a common issue. Hope this information will help you to drive me to the right point.

I know thees are common questions, but I'm not sure all the answer cover my case, and above all I fear to made a mess again, so I faced that I need help.
I can provide more information if needed, like posting dmesg.

Thank you, and sorry for being long.

You have a 6th generation Intel Skylake machine circa 2016, and those pesky kernel developers back in 2014 didn't add support for unknown future hardware for some reason. :lol:

Have you tried this how-to? viewtopic.php?f=16&t=131611

You'll also need to add firmware-atheros from jessie-backports to that list for the wifi with the newer kernel.
The MX Linux repositories: Backports galore! If we don't have something, just ask and we'll try--we like challenges. New packages: AzPainter 2.0.6, Pale Moon 27.3.0, Liquorix kernel 4.11-9, mpv 0.25.0, Kodi 17.3, Ksnip 1.3.1, Mesa 13.0.6

lol, :D

Edit 1: thank you for your reply stevepusser, I read it only after doing the steps I described below, but I appreciate your help

Upgrading the kernel was one step I made, but for sure I made something wrong and got heavy problems on booting.

Anyway I just upgraded to debian stretch then to the kernel 4.9.0-1

I removed unnecessary software by apt-get autoremove after upgrading.

I can control brightness now, which is a good sign, and I can use the wi-fi, even if it remain unstable and less powerful then its potential. On booting a message inform that ath10K failed to load. Checking for the dmesg I saw there are several firmware with similar errors.

Edit 2: it seems that some firmware failed to load but could be found directly. How should I handle this and other errors?

Many thanks in advance.

Skylake graphics also need firmware-misc-nonfree...will check on the Atheros firmware.

Installing firmware-misc-nonfree fixed the graphic card, thank you! I will check for other firmware missing (ath10k, bluetooth and ethernet). anyway moving forward to an optimal installation. I just had bad luck that stretch wasn't released as stable yet and I decided to install jessie from official iso :)

integrated Wi-fi is working and have better speed then before even if it says can't load atheros firmware.
May this be related to my attempt to install ath10k from github when I was with kernel 3.16/jessie?

Edit:
I searched in packages and installed firmware-atheros-20161130-2, r8168-dkms-8.043.02-1 (for ethernet).
Now dmesg reported:

Re: atheros wi-fi + intel VGA on corei5 postinstallation iss

Postby stevepusser » 2017-02-22 19:02

My machine has similar Skylake graphics and Qualcomm Atheros QCA9377 802.11ac wifi--apparently we don't get the firmware dmesg messages with the 4.8 kernel, but I get the same messages as you do with the 4.9 kernel, so it must have added those. Nevertheless, I can't see any difference in the video or wifi performance if I boot to either the 4.8 or 4.9 Liquorix kernels we (MX packaging team) backport to a Jessie base. Debian should have had bug reports on this by now, so we can hope an update to the firmware packages is in the works to get rid of the messages. Sometime another distro such as Siduction updates the firmware on their own--I'll take a look at what they added to their custom update here: http://packages.siduction.org/fixes/poo ... e-nonfree/

Though the Debian "-2" update makes it still seen as higher now...

The "modinfo <module>" command as root will tell what firmware the driver is looking for for a specific device, such as mine:

Code: Select all
# modinfo ath10k_pci
filename:       /lib/modules/4.9.0-11.1-liquorix-amd64/kernel/drivers/net/wireless/ath/ath10k/ath10k_pci.ko
firmware:       ath10k/QCA9377/hw1.0/board.bin
firmware:       ath10k/QCA9377/hw1.0/firmware-5.bin


Which firmware-atheros includes---I am starting to think that the missing firmware has to do with the Bluetooth part of the device.

I noticed critically slow connection (not just slow loading pages which may involve graphics, but also downloading packages from terminal) with kernel 3.16+atheros firmware installed by github kvalo. Don't think it was due to connection because switching to the usb adapter increased performance. Anyway we know there are many factors related to the net, also possible errors I made during installation/configuration.
Now I'm using the integrated wi-fi card with good performance.

Besides that, you may be right thinking about a bluetooth issue. I didn't had the chance to test the bluetooth in jessie (notebook is new and came as freedos, not switching from other OS) I just saw the bluetooth icon on the top bar in gnome and assumed that it was recognized. The error came after the distro+kernel upgrade, so I can only say that I noticed it after that.

I run a dmesg for bluetooth.
