Fails with "DRM_IOCTL_I915_GEM_APERTURE failed: No such file or directory" when i915=/dev/dri/card1 & radeon=/dev/dri/card0

[Hagbard-Celin]

I get this error when running test_va_api or vlc playback with LIBVA_DRIVER_NAME=i965 when i915.ko is /dev/dri/card1 and radeon.ko is /dev/dri/card0:
"DRM_IOCTL_I915_GEM_APERTURE failed: No such file or directory"
Before I set LIBVA_DRIVER_NAME vlc complained:
"vaapi_drm error: Failed to initialize the VAAPI device"
The errors go away if I jump trough a lot of hoops to force the kernel to load i915.ko before radeon.ko but that leads to random X crashes with no error messages whatsoever (even tried enabling extra debugging of i915 in kernel config). It also breaks my early-prink setup.
I run Xorg 1.19.5 on i7-4790 integrated-GPU with SNA detected as gen7.5, gt2 with latest git version of xf86-video-intel, and mesa 17.2.4.
The radeon card is a R5 230 OEM PCIe 1x card used for fbcon.
Also X is always started with -sharevts -novtswitch (The setup equals mult-seat with all keyboard and mouse inputs routed trough a switch to one set.)

Sorry for slow response, does 'vainfo --display drm --device /dev/dri/renderD129' work for you?

[Hagbard-Celin]

No, this is the result I'm getting:

% vainfo --display drm --device /dev/dri/renderD129

zsh: abort      vainfo --display drm --device /dev/dri/renderD129

It works if I replace every occurrence of "card0" and "renderD128" with "card1" and "renderD129" respectively in libva, libva-utils and libva-intel-driver sources, and recompile. In VLC I still have to change to va-via-X11 for it to work, va-via-drm gives the same error even with the adjusted sources.
It seems to me that when selecting the Intel driver with LIBVA_DRIVER_NAME env-variable, libva should select the right card, or we need a LIBVA_DEVICE_NAME (or/and LIBVA_RENDER_DEVICE_NAME) variable too.

[xhaihao]

libva info: User requested driver 'i965'

You set the driver via LIBVA_DRIVER_NAME, could you give a try without LIBVA_DRIVER_NAME when running 'vainfo --display drm --device /dev/dri/renderD129'

[Hagbard-Celin]

I have already set driver with LIBVA_DRIVER_NAME=i965 as stated in my first post. What I am saying is the setting driver should also select the right "/dev/dri/cardx" and "/dev/dri/renderDxxx", as it does not do at the moment. Or, we need additional variable(s) to set those. As it is now, it seems card0 and renderD128 gets hard-coded (at-least in the software I use) when using va via drm, that works badly for people with multiple GPU's.

[Hagbard-Celin]

Sorry I misread your comment, here is result:

% unset LIBVA_DRIVER_NAME 
% vainfo --display drm --device /dev/dri/renderD129    
libva info: VA-API version 0.40.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib64/va/drivers/r600_drv_video.so
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

[xhaihao]

1. I thought your i915 is using card1 and render129 as the title says 'i915=/dev/dri/card1'. Actually your i915 is using card0 and render128 because you changed the loading order for i915.ko and radeon.ko.
   so you should run 'vainfo --display drm --device /dev/dri/renderD128'. You needn't set LIBVA_DRIVER_NAME because the device has been set via option '--device'

2. Even for Intel GPU, there are two different DRI devices, so it is hard for driver to select the device.

3. VA-API provides the interface to accept the file descriptor from app, so it would be better the software can provide an option to select different devices, like as what we did in vainfo.

4. dri2 prime support is needed for the current implementation If you want to select a different driver upon X11.

[Hagbard-Celin]

My Intel card is /dev/dri/card1 and /dev/dri/renderD129 as shown below.
I tried switching load order but that lead to all kind of problems as explained in my first post, so I switched back.

If the driver can not select the devise automaticity; there should be a env-variable, like the LIBVA_DRIVER_NAME does for selecting driver. Implementing a card selection in applications would make sense if the applications where already where the driver is selected. But it is not the driver is selected by libva via LIBVA_DRIVER_NAME, not by the application.
Also, this is a problem in every application using libva via drm, fixing every application seems like lots of duplicate work.

PS: Please be advised that the Nvidia card is mapped to vfio-pci an has nothing to do with this discussion, just in case.

PPS: As I say in the first post; I run libva 1.19.5, that might explain the resulsts not being as you expect. I've tried upgrading to 2.0.0 but VLC failed to compile against it, so I had to go back.
Edit: Sorry, was getting tired, 1.19.5 was Xorg, and I missed libva version info which was 1.8.3.

[xhaihao]

My Intel card is /dev/dri/card1 and /dev/dri/renderD129 as shown below

The output of vainfo shows the driver for your renderD129 is r600_drv_video.so, so I think your Intel card should be card0 and renderD128. It would be better to check the files in /sys/devices/pci0000:00/0000:00:02.0/drm

It is not a VGA compatible controller.

Also, this is a problem in every application using libva via drm, fixing every application seems like lots of duplicate work.

vaGetDisplayDRM(int fd) requires that application provides a right fd.

vaGetDisplayDRM(int fd) requires that application provides a right fd.

And herein lies the problem. You let the driver be set directly in libva with LIBVA_DRIVER_NAME independent of witch application beeing used. But leave the issue of selecting the right fd to the application, leading to the current result where (almost) all are hard-coded with /dev/dri/renderD128. And people belive a pc with Nvidia+Intel or Radeon+Intel is a Optimus/Whatever-AMD-calls-it type Laptop, so the desktop case gets forgotten. Please give us a option to override the device by env variable, like we can with driver, that is all that I am asking.

And this is what I get after running "grep -rl card0 | xargs sed -i 's/card0/card1/g'" and "grep -rl renderD128 | xargs sed -i 's/renderD128/renderD129/g'" on sources of libva, libva-utils and libva-intel-driver and recompile them:

You needn't change the source code, the option of --device should work for you, please check
#186

[xhaihao]

But leave the issue of selecting the right fd to the application, leading to the current result where (almost) all are hard-coded with /dev/dri/renderD128,

AFAIK Both FFmpeg/Libav and gstreamer-vaapi don't use hard-coded /dev/dri/renderD128.

[xhaihao]

Could you run the commands below to check which kernel module creates renderD128 and renderD129

$> sudo cat /sys/kernel/debug/dri/128/name
$> sudo cat /sys/kernel/debug/dri/129/name

Ok, I probably stand corrected. But I've yet to find a GUI-app that let me set this.
