I've been struggling to get all the devices with their drivers to work on my new Skylake / Sunrise laptop chip-set. To make life easier for other out there, I would like to open this thread with the issues I got and how I solved them (still work in progress. This laptop is purchased from BTO, the Netherlands and, like the company name, it's build to order. Meaning, it's not a mayor brand laptop like Asus, HP etc.

List of issues:
  1. DRM not working
  2. NVMe device not showing up in UEFI boot mode (already started a thread on this one)
  3. No PCIe bridge drivers loaded
  4. WiFi not working
  5. No sound
  6. Battery indication in KDE not working, lots of ACPI table warnings in dmesg (seems that ACPI is not working)
  7. Can't power off laptop without holding power button after halt. Reboot works (probably also ACPI related)
  8. Laptop buttons not working
  9. Misc controllers without drivers


Current status up till now:
1. DRM not working
Sky Lake Integrated Graphics. Solved by pulling in kernel linux-4.4.* and sys-kernel/linux-firmware-20151207. Since I compile my DRM driver into kernel, I needed to include the following firmware files: i915/skl_dmc_ver1.bin i915/skl_guc_ver1.bin i915/skl_guc_ver4.bin. You can try your luck with stable linux-4.1.15 and "Enable preliminary support for prerelease Intel hardware by default ". Don't forget to deselect all the framebuffer devices, like me :oops:

3. PCIe bridge drivers not loaded
Solved by linux-4.4.* and pcieport driver.

4. WiFi not working
This is a Intel Dual Band Wireless AC 3165. Same thing, needed linux-4.4.* and recent linux-firmware to make it work. One needs to select "Intel Wireless WiFi MVM Firmware support" under iwlwifi driver also.

5. No sound
Sunrise Point-H HD Audio, with realtek chip. Need >sys-kernel/linux-firmware-20151207. So at the moment of this writing you'll need version 99999999 to pull in the latest GIT version. Since I kept puzzling how to get it work, I just selected all the codecs as Modules. In the end the system loaded these: snd_hda_codec_realtek, snd_hda_codec_hdmi, snd_hda_codec_generic, snd_hda_codec, snd_hda_intel. I'm not sure if it mattered in the end, but I also pulled in media-sound/alsa-utils-1.1.0 and media-libs/alsa-lib-1.1.0

As a reference my output of lspci -kvm up to this point:

Laptop buttons not working


sometimes they work with the experimental features / wmi stuff of kernels.

See my bug at kernel.org

https://bugzilla.kernel.org/show_bug.cgi?id=106901

The only way is to generate the same bug report I did for the keys. Feel free to reutilize on how I did it.

it seems there is a new way of handling stuff, called wmi. and guess what windows bla bla bla standard, and its broken, badly implemented by uefi.

any manufacturer has a support forum. bug them there tell them their hardware is not working and you will not buy anything from them again. when complaints pile up they may do something.

Which BTO laptop do you have ? I'm considering a BTO laptop (i am/was planning to place the order this weekend, looking at the 14" U-book model).

V-book 15 inch. It is a good price, you get for the performance and you have the option not to buy Windows :D. But I find that the technology is a bit new, so expect to some troubles on the road. Don't expect to use any life CD out there with a LTS / latest stable kernel to boot to OS with network and graphics support. I just used my old laptop to install Gentoo in a chroot on a USB disk with the latest gentoo-sources in ~arch, boot from there and copy the root and kernel over to my new laptop. Configured the profiles, USE and build flags after that on my new laptop.

Which is exactly what got me interested in BTO, i've emailed them and they are even willing to remove their "free trial" version \o/

Which is exactly what is holding me back after reading your initial post :)

That sounds doable. So the drivers are basically there, but in kernels which are not (yet) marked as stable ?

@muhlemmer
I got my laptop about a week ago and all the important parts are working. A recent kernel (4.5.x) and linux-firmware (20160331) did the trick. I only thing that isn't working for now is the built-in SD/MMC cardreader, Is it working for you ? And if so, which kernel modules are you using ?

Thanks in advance.

htose sd card readers are most usb ones, check the usb section of your kernel, and kernel related logs, also check if htose are turned on.

In neither lspci or lsusb i can find anything i can identify as the cardreader. Once i know the device i know how to find the correct driver for it.

By process of elimination, it must be this one...

Thanks for your help Ant P., that is indeed correct !
I just recompiled my kernel to include these drivers and it works.

I guess I had luck mostly with mine (Schenker S306 btw)
Code:

Linux ultrabook 4.5.2-gentoo #1 SMP PREEMPT Wed Apr 20 23:16:58 CEST 2016 x86_64 Intel(R) Core(TM) i7-6500U CPU @ 2.50GHz GenuineIntel GNU/Linux

Almost everything works, even keyboard LEDs and special keys.
Things not working/issues:
-Screen flickering with the xf86-video-intel driver, no matter what version.
-After suspend, KDE doesn't react to mouse clicks. I have to change VTs twice(!), then it works 8O
-The intel 8260 WIFI card will not reliably detect the 5Ghz network. I have to deactivate/activate wifi several times to get it working. That's by far the most annoying issue.

That's odd. I get the same thing sometimes on my completely mundane desktop, with the same workaround (well, I could unplug the mouse but that loses my xset settings), except it only ever happens after a display DPMS suspend. Feels like it only started happening in the last few months too...

Update:
WIFI issue has magically disappeared (it was maybe an issue with powertop).
Screen flickering is gone with recent kernel/firmware/graphics update. Happy camper :)

Do you have ACPI working? Does the system power off normally? I don;t have battery indications and during shut-down the system is stuck at "reboot: system halted". Had these issues since forever and hoped that support will come with newer kernel, but maybe I'm missing something in the config. Now at vanilla-4.8.1

Yes, works. Just that in KDE the sound output is not enabled after hotplug and I lost my patience with that. If I'm watching movies with SMplayer, I can manually select the HDMI as sound output and it works. System sounds, Amarok etc doesn't.

As for a general update of the situation. Since kernel 4.9 series the power-off is working, I'm able to fully boot in UEFI and mount NVMe devices etc. After recent releases of sys-kernel/linux-firmware I am now using the stable tree version 20161205 and kernel series 4.9 recently have a stable version as well. It is safe to conclude that this skylake hardware is supported by now without having to pull in development versions of kernels and firmware.

I still have some ACPI functionalities that are not working. I don't have power source info (battery nor adapter state) and stand-by doesn't work. If I have time I want to start to raise bugs to the mainline kernel bugzilla, but it's hard find resources how to write a good ACPI bug. Like what kind of info do they want to be included. Error logs? what verbosity level of the kernel? ACPI dirver specific debug info? acpidump output? Do I need to raise a bug for every specific missing function or one more general for this platform? Some advice and examples would be appreciated.
