Hi,
first, I'm not sure whether my post belongs here or to 'installing'. Feel free to move it, moderators.

I have a skylake based intel nuc box, and I still experiencing un-smooth, 'micro-stuttering' window frames when moving around in gnome, it just doesn't feel 'right'.
My complaint is not about speed, everything runs bleeding fast.

Code:
Ganymed rudi # lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Sky Lake Integrated Graphics (rev 0a)


Code:
rudi@Ganymed ~ $ dmesg | grep drm

Try to add this in xorg.conf:
Code:
Section "Extensions"
   Option "XVideo" "Disable"
EndSection

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod"  "sna"
   Option      "TearFree"     "true"
   Option      "DRI"         "true"

It get's worse: with kernel 4.8.5-gentoo I get:

Code:
Direct firmware load for i915/skl_dmc_ver1_26.bin failed with error -2


What's going on, intel?

@Wallsandfences

There's a new entry in Gentoo Intel wiki for that issue

https://wiki.gentoo.org/wiki/Intel

Code:
If you are using Kabylake, Skylake or Broxton Intel Graphics, install sys-kernel/linux-firmware.

root #emerge --ask sys-kernel/linux-firmware
Otherwise you might see errors such as

kernel: i915 0000:00:02.0: Direct firmware load for i915/skl_dmc_ver1.bin failed with error -2
kernel: i915 0000:00:02.0: Failed to load DMC firmware [https://01.org/linuxgraphics/intel-linux-graphics-firmwares], disabling runtime power management.
in dmesg. Include the files required for your GPU in the kernel, in this case

Device Drivers  --->
    Generic Driver Options  --->
        -*- Userspace firmware loading support
        [*] Include in-kernel firmware blobs in kernel binary
            (i915/skl_dmc_ver1.bin)
            (/lib/firmware) Firmware blobs root directory

I saw that I had an additional '/' after 'firmware'
I changed that, but to no avail.

Code:
 Your kernel
  [*]   Include in-kernel firmware blobs in kernel binary          │ │ 
  │ │    (i915/skl_dmc_ver1.bin i915/skl_guc_ver6.bin) External firmware


Code:
 Your dmesg
Direct firmware load for i915/skl_dmc_ver1_26.bin failed with error -2


In you dmesg it says i915/skl_dmc_ver1_26.bin and in your kernel you have i915/skl_dmc_ver1.bin i915/skl_guc_ver6.bin

Notice the ver1_26 from dmesg and compare to your kernel.

Hi,
it is softlinked:

Code:

/lib/firmware/i915

-rw-r--r-- 1 root root   8928 13. Jun 09:29 skl_dmc_ver1_26.bin
lrwxrwxrwx 1 root root     19 13. Jun 09:30 skl_dmc_ver1.bin -> skl_dmc_ver1_26.bin


and the blob is created according to 'make'-output

I had the same issue you had and I solved it by doing that when I built the driver into the kernel.

Perhaps it doesn't accept it when it's softlinked.

Hi, the dmc-part works now thanks to marax_faraii!

Code:
   0.511310] [drm] Finished loading i915/skl_dmc_ver1_26.bin (v1.26)

The guc-part still doesn't work, anyone knows why?
