Glad to help, QuickShot! I was surprised nobody else had run into this issue yet as far as I can tell. I can handle a ton of simultaneous transcoded streams now on my z370 8700.

I was able to get this working by adding the the kernel parameter i915.alpha_support=1. You can get this to work as well by editing syslinux.cfg as explained here: https://lime-technology.com/wiki/Boot_Codes Thanks for the help everyone, great community here!

I just found this: https://www.phoronix.com/scan.php?page=news_item&px=Linux-4.15-CFL-No-Alpha. I also upgraded to the unRAID RC to see if it would work with i915, no luck. Anyone else have coffeelake z370? I've been searching on google and cannot find anything specific to unRAID and coffee lake iGPU transcoding.

I'm on z370 with a i7 8700 and am trying to get intel quicksync hardware acceleration working within plex. I have followed both: https://lime-technology.com/forums/topic/40463-support-linuxserverio-plex-media-server/?do=findComment&comment=544290 and https://lime-technology.com/forums/topic/40463-support-linuxserverio-plex-media-server/?do=findComment&comment=543984 but I cannot get it to work since /dev/dri is not available on my unRAID server. I have made sure I have the iGPU enabled and set explicitly in my bios. root@unRAID:/dev# modprobe i915 root@unRAID:/dev# lsmod | grep i915 i915 1118208 0 iosf_mbi 16384 1 i915 i2c_algo_bit 16384 1 i915 drm_kms_helper 122880 1 i915 drm 294912 2 i915,drm_kms_helper intel_gtt 20480 1 i915 i2c_core 36864 5 i2c_algo_bit,i2c_i801,i915,drm_kms_helper,drm video 36864 1 i915 backlight 16384 2 video,i915 button 16384 1 i915 root@unRAID:/dev# modprobe i915 root@unRAID:/dev# lsmod | grep i915 i915 1118208 0 iosf_mbi 16384 1 i915 i2c_algo_bit 16384 1 i915 drm_kms_helper 122880 1 i915 drm 294912 2 i915,drm_kms_helper intel_gtt 20480 1 i915 i2c_core 36864 5 i2c_algo_bit,i2c_i801,i915,drm_kms_helper,drm video 36864 1 i915 backlight 16384 2 video,i915 button 16384 1 i915 root@unRAID:/dev# chmod -R 777 /dev/dri chmod: cannot access '/dev/dri': No such file or directory I'm not sure if this is at all related, but I noticed some kind of blacklist in /etc/modprobe.d, but I am not familiar with how this works. root@unRAID:/etc/modprobe.d# ls /etc/modprobe.d/ README blacklist-i915.conf iommu_unsafe_interrupts.conf kvm.conf scsi-sata-controllers.conf Any ideas? I have attached my diagnostics. Wondering if this is caused by my BIOS version, coffee lake, or z370. unraid-diagnostics-20180103-0123.zip
