PLEX doesn't do HW Transcoding on Fedora 30 (ver 5.6) running on Intel i9-9900 (SGC SonicTransporter)

Chuck:
Can you determine from these BIOS screenshots whether QSV is enabled? I couldn’t find a reference to QSV under the Graphics Configuration Section (ADVANCED).

ChuckPa · September 22, 2021, 7:17pm

What’s under `Graphics Configuration’ ?

That looks like an important one

herbg · September 22, 2021, 7:35pm

See photo 4 … “Graphics Configuration” at the top, below the “Advanced” tab.

ChuckPa · September 22, 2021, 7:55pm

Thanks. that just tells us you can change the status of the onboard VGA adapter.

It’s not showing the status of the QSV.

Look here. you should have the same. See the bus address ?

Notice the PCI address.

Without this , there’s no way to access the internal i965

That should correspond to:

[chuck@lizum module.1989]$ sudo lspci | grep -i graphics
00:02.0 Display controller: Intel Corporation HD Graphics 630 (rev 04)
[chuck@lizum module.1990]$

@agillis1970 will have to check this as I can’t access the OS

ChuckPa · September 22, 2021, 8:06pm

See how easily it resolves and can be confirmed ?

ChuckPa · September 22, 2021, 8:26pm

May I please have a set of Plex’s logs?

Settings - Server - General - Show Advanced
Make sure DEBUG is checked
Make sure VERBOSE is not checked
SAVE if you make changes
Restart Plex

Here you go, Chuck!

I used the 30 sec JellyFish Test File (jellyfish-55-mbps-hd-h264).

ChuckPa · September 23, 2021, 1:32am

It’s clearly not seeing the hardware.

If this were a no-tonemapping problem, I’d have that immediately.

CPUSKU = the 4 digits (9900 part for your CPU)

   # i915 present?
    if [ $Havei915 -gt 0 ]; then

      # Test for IntelComputeRuntime or Beignet based on CPUSKU  (SKL+ and select Xeons)
      [ $HaveIntelCore -gt 0 ] && [ $CPUSKU -gt 2000 ] && [ $CPUSKU -lt 9000 ] && NeedBeignet=1 && NeedOpenCL=1
      [ $HaveIntelCore -gt 0 ] && [ $CPUSKU -gt 1000 ] && [ $CPUSKU -lt 2000 ] && NeedIntelCompute=1 && NeedOpenCL=1

Looks like it’s seeing the hardware it shows up in lsmod quite a few times

Another question - is the Intel MediaSDK required? I know programs like Handbrake require it.

ChuckPa · September 23, 2021, 4:15pm

@agillis1970

No. Plex provides all the libraries and codecs needed.

The only requirement is the host + OS provide access to the QSV via /dev/dri

herbg · September 23, 2021, 4:54pm

Chuck:

Andrew needs to know how to get the OS to enable QSV. Once enabled, my understanding is that Plex will do the rest – do I have that right?

ChuckPa · September 23, 2021, 5:05pm

To make the OS (kernel) see the QSV (which is a device on the PCI bus as I show above), the runtime libraries need to be included with the OS distro.

Is the kernel driver there ? (the KO)

dri is the manifestation of the drm (display rendering management) subsystem.

It’s been a while since I got this deep into the kernel and supporting drivers (internal and external).

agillis1970 · September 23, 2021, 7:43pm

Yes the driver is there. See my post above with the output of modinfo i915.

The modinfo command returns info about a Kernel module in the runtime kernel. In this cases it returned a lot of info about the i915 module. I just don’t understand and of it.

ChuckPa · September 23, 2021, 8:07pm

Can you take a separate workstation machine, load FC30 on it, let it get updates,
and get to QSV?

i can’t help but think something important accidentally got pruned.

We have a lot of redhat/fedora users and there haven’t been any complaints so that makes me ask “Why is this one so special?”

herbg · September 23, 2021, 8:13pm

Chuck:

Can you translate to English for me? Are you saying the OS is enabling QSV? I thought you said my log files indicate that it is not.

ChuckPa · September 23, 2021, 8:20pm

@herbg

yes, the OS is what enables QSV.

In Windows, you have drive letters to point to each device, right? (C:, D:, E:, etc)

In Linux, it does the same for normal files PLUS it maps hardware devices into the file system so we can access them.

This mapping is what Plex needs. It needs to access the QSV device which the kernel detects and then maps into the file system in directory /dev/dri and assigns names card0 for the raw device and renderD128 for the accessible rendering device (the i965 interface to the QSV ASIC) which does the transcoding. The number 128 has significance to the kernel but is just a name to us.
