Intel media server driver problem

[Tomaž_H_]

CentOS version: 7.3.1611
CentOS kernel: 3.10.0-514.el7.x86_64
Processor: Intel Xeon e3 -1585 v5
Motherboard: Xeon x11SSV-M4F (Intel C236 chipset)
Graphics card: Intel Corporation Iris Pro Graphics P580 (integrated on CPU)

I am trying to set up hw accelerated encoding and decoding using quicksync. I checked all of the requirements listed in the R3 Getting started manual and based all the requirements seem to be met.

I followed the new R3 installation notes of Intel Media Server Studio, specifically the gold version install. I've set up the "Development and Creative Workstation" base environment, done all the prerequisite steps and ran the install script. Everything seems to go perfectly, however that's not the case. While the /opt/intel/mediasdk/ is properly populated (it is missing the builder folder tho), however, the graphics card device node is nowhere to be found in /dev/dri, as the dri folder doesn't even exist.

vainfo returns this:
   error: can't connect to X server!
   error: failed to initialize display
   Aborted (core dumped)

I've checked dmesg logs and found this ():
   Initialized drm/i915 compat module 20170620-16.5.2-64009-k422e5bf

Shouldn't it say "VGA compatible controller" tho?
   00:02.0 Display controller: Intel Corporation Iris Pro Graphics P580 (rev 09)

I've set the Primary Display in BIOS as AUTO, since choosing IGFX makes the computer unable to even reach BIOS and needs to have BIOS settings reset by taking out and then putting back the motherboard battery in. Integrated graphics are set to ENABLED.

I have no idea what else could go wrong, so I decided to ask for help here. Any ideas on what could go wrong? as I don't even know where the problem is, much less how to fix it right now.
Thanks in advance

I really do hope I am posting this in the right forums.

Hi There,

I think your kmd part installation is not correct. you may check this in the installation script.

Thanks,

Zachary

First of all, thanks for the answer. I've checked kmd installation. Seems to go perfectly well to me, but I did have to add --nosignature flag to rpm inside the install script, otherwise I would get NOKEY error. Same goes with libdrm.

Installing kmod-ukmd-16.5.2-64009...

Working. This may take some time ...
Done.

Also checked if kmd is installed, it is, but dri folder still missing.
# yum list installed | grep kmd
kmod-ukmd.x86_64                       16.5.2-64009.el7.centos    installed

I am still somehow convinced that the problem is with lspci not saying "VGA compatible controller"
   00:02.0 Display controller: Intel Corporation Iris Pro Graphics P580 (rev 09)

Edit: Nvm, found out that it doesn't matter whether it says VGA compatible or Display controller.

Is it ok that the memory and I/O ports are disabled?

Found the solution in one of the forum posts: https://software.intel.com/en-us/forums/intel-media-sdk/topic/635235

THE TOOL LISTED THERE HELPED ME OUT GREATLY AND IMMEDIATELY POINTED OUT THE ERROR TO ME. YOU SHOULD PROBABLY INCLUDE THE TOOL IN THE INSTALLATION GUIDE, AS IT HAS INVALUABLE INFO WHEN IT COMES TO DEBUGGING THE INSTALLATION.

Here is the solution, if anyone stumbles upon this thread in the future with similar problems: I've had to remove the "nomodeset" flag from /etc/default/grub and then update the config of both /boot/grub2 and /boot/efi. Couldn't have known I had to change BOTH without the tool.đ
