Intel Gfx driver is not found

[RySAP]

Hi

I'd like to decode RTP H.264 video stream received from Network camera.

But installation of Media SDK failed. 

Downloaded libva, libva-utils, Gmmlib, media-driver, and MediaSDK from Github.

Build by gcc 8.3.1 (devtoolset-8）and installed.

　 libva: https://github.com/intel/libva/releases/tag/2.7.0

     libva-utils: https://github.com/intel/libva-utils/releases/tag/2.7.1

      Gmmlib: https://github.com/intel/gmmlib/releases/tag/intel-gmmlib-20.1.1

     Driver: https://github.com/intel/media-driver/releases/tag/intel-media-20.1.1

     Media SDK and Samples: https://github.com/Intel-Media-SDK/MediaSDK/releases/tag/intel-mediasdk-20.1.0

I added option "--display drm --device /dev/dri/renderD129", but it was same error message.

I made following initialize code.  But the device file is not found.

int open_intel_adapter()
{
std::string adapterPath = "/dev/dri/renderD";

char driverName[5] = {};
mfxU32 nodeIndex = 128;

for (mfxU32 i = 0; i < 16; ++i) {
std::string curAdapterPath = adapterPath + std::to_string(nodeIndex + i);

int fd = open(curAdapterPath.c_str(), O_RDWR);
if (fd < 0) continue;

drm_version_t version = {};
version.name_len = 32;
version.name = driverName;
ioctl(fd, DRM_IOWR(0, drm_version), &version);
if(!strcmp(driverName, "i915")) return fd;
close(fd);
}
return -1;
}

my  environment is;

- OS       CentOS Linux release 7.6.1810
- CPU   Intel(R) Core(TM) i7-6800K CPU @ 3.40GHz
- GPU    NVIDIA GeForce GTX 1080
         Following Nvidia driver is installed/
　NVRM version: NVIDIA UNIX x86_64 Kernel Module 450.80.02 Wed Sep 23 01:13:39 UTC 2020

I disabled Nouveau driver.
　# sudo mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-nouveau.img
　# sudo dracut --force --omit-drivers nouveau /boot/initramfs-$(uname -r).img $(uname -r)
　# echo "blacklist nouveau" | sudo tee /etc/modprobe.d/modprobe.conf

Question

Could you tell me why intel Gfx driver is not found?

And I 'm planning to try another PC.   Its CPU is Intel(R) Xeon(R) W-2133 CPU @ 3.60GHz.

Does Media SDK support   Xeon W-2133 ?
