Hi,

I'm getting this error on my Ubuntu20.04 (it's a KVM):

libva error: vaGetDriverNameByIndex() failed with unknown libva error,driver_name=(null)

Here is my configuration :

root@test-ssh:~# cat /proc/cpuinfo | grep "model name" | uniq
model name      : Intel Core Processor (Skylake, IBRS)

But media-driver can run successfully on the physical machine on which this KVM is built.
Here is the physical machine configuration :

root@ubuntu-1:~# cat /proc/cpuinfo | grep "model name" | uniq
model name      : Intel(R) Core(TM) i7-8705G CPU @ 3.10GHz
root@ubuntu-1:~# lspci -nn|grep VGA
01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Polaris 22 XL [Radeon RX Vega M GL] [1002:694e] (rev c0)

What can be done?

not intel card? it is AMD card , right?
could you help to check the nodes under /dev/dri/ to find renderDxx
then call vainfo --display=drm --device=/dev/dri/renderDxxx to check whether it work

Yes, but I can successfully deploy Media-Driver on this physical machine of AMD card. This is the output information:

However, when I run Media-Driver in the KVM deployed on this physical machine, even if I achieved CPU pass-through, it still fails.This is the KVM output information:

I built a KVM and did pass-through to make it fit the requirements. Here is the configuration :

root@test-ssh:~# cat /proc/cpuinfo | grep "model name" | uniq
model name      : 11th Gen Intel(R) Core(TM) i5-1135G7 @ 2.40GHz

But it still not work.

I suspect the /dev/dri has an impact

root@test-ssh:~# ls /dev/dri
ls: cannot access '/dev/dri': No such file or directory

Now, what can I do?

Hi @WARUKUCHI, seems i915 was not loaded successfully in your environment.
Could you try to load it manually, and get dmesg then?

just like Xiaogang said, we should check why there are no any device node under /dev/dri. if a gpu is installed correctly, it should have a node under /dev/dri. if the configuration is dual card (intel I-graphics and AMD D-graphics) there should be 2 device nodes (or 4, because there are also /dev/dri/devicexxx). so, I suppose the GPU is not enabled on your KVM.

Make sure to check VM kernel version. For TGL, kernel 5.4 needs to apply i915.force_probe=*. And recommend to use newer stable kernel like 5.10 in guest.

Thanks for advice, now I build a new KVM. Here is the configuration :

Segmentation fault (core dumped)

This error points to RAM, but it is still the case after I expend the memory.
I also found several possible reasons for “Segmentation fault ”:
Such as dereferencing null pointers; Access inaccessible memory space (such as kernel space); Access non-existent memory address.
In reference .so file, these kinds of practices are easy to lead to segment errors, which are basically caused by the introduction of wrong parameters to the C program. But it can run successfully on the physical machine.

dumb question, why not use gdb to check the backtrace of the segmentation failed?

Hi,
I'm running on Ubuntu 22.04 and I have this same issue when I try to run any applications that is not on Ubuntu at the installation. So, for example, I have this issue if I try to run Google Chrome that I've downloaded from the official website, but I don't have if I try to run Firefox, which is on Ubuntu by default, even if I delete and the install Firefox again.
I'm not an expert on the field but I'll try to explain myself as best as I can.
Let's take Google Chrome as an example:
if I try to open Google Chrome by clicking on the icon in the Applications Menu, the application opens but the window does not. If I hoover on the application's icon with the mouse, it tells me that there's a window opened, but the window does not show up.

If I try to run Google Chrome from command line, I get the same result and this output:

libva error: vaGetDriverNameByIndex() failed with unknown libva error, driver_name = (null)
[7349:7349:1027/143428.736865:ERROR:gl_surface_presentation_helper.cc(260)] GetVSyncParametersIfAvailable() failed for 1 times!

If I try to open the window again:

[7349:7349:1027/143452.480636:ERROR:gl_surface_presentation_helper.cc(260)] GetVSyncParametersIfAvailable() failed for 2 times!

If I try to run it as a root user, I get this error:

[7644:7644:1027/143959.715598:ERROR:zygote_host_impl_linux.cc(90)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180.

I hope I've been clear enough and thanks for your help.

I'm having the same issue, well kinda of. I get the same message when I try to play a movie in starplus, but if play HBOmax, youtube or whatever it's evertyhing ok. I don't know what it is.

[Default Toggle Names]
lazy_clear_resource_on_first_use: https://crbug.com/dawn/145: Clears resource to zero on first usage. This initializes the resource so that no dirty bits from recycled memory is present in the new resource.
use_temporary_buffer_in_texture_to_texture_copy: https://crbug.com/dawn/42: Split texture-to-texture copy into two copies: copy from source texture into a temporary buffer, and copy from the temporary buffer into the destination texture when copying between compressed textures that don't have block-aligned sizes. This workaround is enabled by default on all Vulkan drivers to solve an issue in the Vulkan SPEC about the texture-to-texture copies with compressed formats. See #1005 (KhronosGroup/Vulkan-Docs#1005) for more details.
vulkan_use_d32s8: https://crbug.com/dawn/286: Vulkan mandates support of either D32_FLOAT_S8 or D24_UNORM_S8. When available the backend will use D32S8 (toggle to on) but setting the toggle to off will make it use the D24S8 format when possible.
vulkan_use_s8: https://crbug.com/dawn/666: Vulkan has a pure stencil8 format but it is not universally available. When this toggle is on, the backend will use S8 for the stencil8 format, otherwise it will fallback to D32S8 or D24S8.

Libva error: vaGetDriverNameByIndex() failed with unknown libva error, driver_name = (null)
but vainfo success with wayland, so I suppose it is because of xwayland. could you try the latest master which enabled dri3 support and should work with xwayland

@XinfengZhang I can confirm it does work with chrome 109 under X11 (HEVC playback works then and codecs are listed).

Tried building master (-9999 on gentoo), but it currently fails build process. Will try again later.

I had the same error after a reboot when trying to open Google Chrome. I had export GTK_IM_MODULE=wayland in my shell rc, changing it to export GTK_IM_MODULE=ibus fixed the error on Ubuntu 22.04 LTS with latest updates. vainfo and vainfo --display drm --device /dev/dri/renderDxxx were working even with the wrong setting.
