jlm_devel,
I suspect that you don't have the hardware for i2c_designware. If you do, its not working because the bus never becomes ready :)
If you have anything like i2c_designware is the output of lsmod, modprobe -r it/them.
If its built into your kernel, remove it. That's a kernel rebuild.
Your Intel kernel space stuff is in two pieces. The driver and its firmware.
Both bits have to come together when the driver is initalised.
That means that both need to be be configured in the kernel or both on the root filesystem.
| Code: | -*- Firmware loading facility
(i915/skl_dmc_ver1_27.bin) Build named firmware blobs into the kernel binary
(/lib/firmware) Firmware blobs root directory |
is only useful if the kernel driver is configured as <*>, its harmless otherwise.
As as aside, the kernel can update your CPU firmware. There is a wiki page for that. It involves listing your firmware there.
We can see that you are getting all the right bits together but not that they are actually used.
That's what your /var/log/Xorg.0.log will tell.

Hi,
rebuild finished.... but seems worst...
first : now the i2c errors are gone so I can use the dmesg
second :

jlm_devel,
when I start vlc from command line I get:

Did you try different mpeg-files ? If yes, you could try using the stable intel-driver I use (delete ~amd64 and use only amd64).
(your kernel log for DMC firmware is the same as mine = ok) |

| This file you are trying to play, is it 8-bit? I doubt your GPU can do more than 8-bit in hardware. I may be wrong. But this is something you should check on. |

ok after lot of rebuild, now the video decoding is smooth!!!!! hardware accelerated!!! (at least for VLC)
| Code: | USE="-test glamor vaapi openmp drm opengl egl gles2 "
CPU_FLAGS_X86="aes avx avx2 fma3 mmx mmxext popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3"
VIDEO_CARDS="intel i965 iris" |
also update to 5.9.1-gentoo-x86_64 kernel.
vlc show on command line : | Code: | $ vlc GH010797.MP4

but the "i2c_designware i2c_designware.0: timeout waiting for bus ready" filling dmesg came back... so can't "dmesg |grep i915"
mpv state didn't changed.... still A/V synchro loss...
next step is switching to new gentoo profile... |

Hi,
I dig this topig, since I've now switched to new 17.1 profile, everything seems to worked well...
but now I only see a few seconds of video, then black screen for the rest of the time and vlc end with a SEGFAULT....
any idea? |

what I notice, is that the display is rather instable...
1- chromium crash ofter without raison... when I launch it in a term, I saw some error related to some shader compilation error
2- on vlc, the same mp4 hevc file will be displayed smoothly, and after some plays, VLC might hangs (have to kill it) or finish by decoding the first 5s, and display a black screen after
3- If I continue opening hevc files the x server will crash after a few attemps... on the console I saw some errors related to AIGLX....

I wonder what firmware to use :
https://wiki.gentoo.org/wiki/Intel#Modesetting_DDX says to use i915/skl_dmc_ver1_27.bin
but latter on the wiki they says For Gen9 and Gen9.5 GPUs, GuC/HuC firmware won't be loaded by default
I've no idea about what firmware correspond to what device...
skl_guc_32.0.3.bin
skl_guc_33.0.0.bin
skl_guc_ver1_1059.bin
skl_guc_ver1.bin
skl_guc_ver4_3.bin
skl_guc_ver4.bin
skl_guc_ver6_1.bin
skl_guc_ver6.bin
skl_guc_ver9_33.bin
skl_dmc_ver1_23.bin
skl_dmc_ver1_26.bin
skl_dmc_ver1_27.bin
skl_dmc_ver1.bin
skl_huc_2.0.0.bin
skl_huc_ver01_07_1398.bin |

I have an Intel i7-6700 and I use only the integrated gpu.
This processor is the 6.th CPU generation AND the 9.th GPU generation.
For this CPU you need skl_dmc_ver1_27.bin (I told you before in this thread) ! Forget guc and huc ! The info for this you find in:
https://wiki.gentoo.org/wiki/Intel
Next is your profile. I have: default/linux/amd64/17.1/desktop/plasma (without systemd; but this should make no difference)
It is important to set the correct profile, because the profile does not set only global USE-flags, it sets individuell USE-flags per package (some packages with dri3 or gles2 - some without). So, you shouldnt set it by yourself in your make.conf ... except: "vaapi". And you should set VIDEO_CARDS="intel i965 iris" in your make.conf
A difference to your system: I have a stable system and you use the unstable iHD_drv_video. I dont know how much this cause problems.
The next difference is: I use the outdated Intel DDX with sna (because I tested it against the modesetting and the result was: it is faster). And for this I have in my make.conf additionally this:
| Code: | | USE="$USE sna uxa vaapi xvmc" |
(and of course the needed /etc/X11/xorg.conf.d/20-intel.conf)
Dont set any global "drm, egl, gles, gles1, gles2, dri, dri2, dri3, opengl" in your make.conf - this should be done ONLY from your profile setting !! |

seems that I found....
in fact there is 3 blobs to embed into the kernel....
you need to add to kernel parameters the "i915.enable_guc=2" then reboot, in dmesg seek for
| Code: | kernel: [ 1.294069] [drm] GuC: Failed to fetch firmware i915/kbl_guc_ver9_33.bin (error -2)
kernel: [ 1.294079] [drm] HuC: Failed to fetch firmware i915/kbl_huc_ver01_07_1398.bin (error -2) |
this give you the 2 others build to embed,
then do a genkernel --menuconfig all
go into | Code: | | Device Drivers ---> Generic Driver Options ---> Firmware loader ---> |
and into | Code: | | () Build named firmware blobs into the kernel binary |
put for me | Code: | | i915/skl_dmc_ver1_27.bin i915/skl_guc_33.0.0.bin i915/skl_huc_2.0.0.bin |
reboot and do dmesg |grep i915

will try the sna driver because I still have lot of scrolling glitches and video glitches...
what puzzle me is that you says that " I have a stable system and you use the unstable iHD_drv_video" and I don't know what is the iHD_drv_video, how I did I installed this driver? where could I have configured it? .....
thanks a lot! |

Presumably you have an "ACCEPT_KEYWORDS=~amd64" somewhere. Your driver comes from:
| Code: | * x11-libs/libva-intel-media-driver [ Masked ]
Latest version available: 9999 |
Mine is:
| Code: | * x11-libs/libva-intel-driver
Latest version available: 2.4.1 |
As I said I have also the deprecated Intel-driver:
| Code: | # emerge -pvD xf86-video-intel
These are the packages that would be merged, in order:
Calculating dependencies... done!

| video glitches were coming from the modesetting intel driver.... now I'm on SNA and video is fluid and no "single buffering" / "no sync update".... think that the wiki should be updated.... |
