Re: [Beignet] few questions on Beignet-OpenCL-ICD v1.2.0 regarding X11 and kernel patches

2016-09-26 Thread Seva Gluschenko 
Hi everyone,


My problem is solved, finally, and I think that would be reasonable to share 
the solution here, even though it has no connection to Beignet, just in case 
somebody hits the same problem next time. The solution is simple:

# modprobe i915_bpo modeset=1

The reason this problem ever appeared is that our IT infrastructure provider 
issued "nomodeset" as default option in the /etc/default/grub file because of 
numerous problems with older i915 modules.

Thank you very much again for useful hints and patience.


Best,

Seva

As my understanding, /dev/dri is create by drm's kernel space driver, and it is 
not only available together with X.
Actually X is one of /dev/dri's clients, all graphics stack such as wayland and 
vaapi use it.

Re: [Beignet] few questions on Beignet-OpenCL-ICD v1.2.0 regarding X11 and kernel patches

2016-09-25 Thread Weng, Chuanbo 

How did you work out a non-X ubuntu? Installed an ubuntu server edition?
/dev/dri is supported by linux kernel, try this command to see whether there is 
drm and i915 module:
lsmod | grep i915
Maybe you can update your linux kernel to latest version and try again.

Hi Weng,


I might be missing something, but it seems like the DRI is only available 
together with X. That's why I'm specifically interested if you know how to make 
/dev/dri appear in non-X environment.

On the other hand, I made all my exercises as root, and I've just figured out, 
though, that I don't have /dev/drm either, even though kernel reports it was 
initialized in my system:

2016-09-23 Thread Weng, Chuanbo 
Hi Seva,
What Rong means is that Beignet will try to open drm device exposed in 
/dev/dri/ (Actually, In non-X environment, 
Beignet will try to open render node such as /dev/dri/renderD128, if failed it 
will then try to open prime primary node such 
as /dev/dri/card0).
Beignet can run on DRM mode, but you should better be a root user.
You can try to run utest as suggested by Rong, and report the message 
to us  (if running utest failed).
I strongly suggest you take a look at README.md, which includes many 
basic info of Beignet usage. : )

There is only beignet-opencl-icd's output, can't find the error message from

To run utest, you need "make utest", then run ". ./utests/setenv.sh" and at

It seems open device failed, can you also list the device under /dev/dri?

Re: [Beignet] few questions on Beignet-OpenCL-ICD v1.2.0 regarding X11 and kernel patches

2016-09-22 Thread Seva Gluschenko 
Hello Rebecca,

Please accept my apologies for being not very informative. I'm running Ubuntu 
16.04.1LTS x86_64 on Intel Core i7-6700, and I had the patched Linux kernel 
4.4.21-intel.r16.5 and Intel's opencl_runtime_16.1.1_x64_ubuntu_6.4.0.25 
installed in parallel with Beignet. After erasing all that stuff and switching 
back to the standard kernel (4.4.0-38-generic, in fact 4.4.17 with patches, 
according to ChangeLog), with Beignet as the only ICD provider, clinfo no 
longer fails without X. Unfortunately, it does not find any GPU either:

Could you please drop me some hints on where to dig further? I feel like I'm 
stuck.

BTW, thank you very much for the debian package that I found in Debian sid, I 
took its controls and used them to build a package for Ubuntu, with some

Re: [Beignet] few questions on Beignet-OpenCL-ICD v1.2.0 regarding X11 and kernel patches

2016-09-21 Thread Rebecca N. Palmer 
I just built beignet in a chroot with no X11 installed; it didn't have 
that string, and worked (when run as root - for ordinary users, it 
failed with "/dev/dri/card0 not authenticated", but this is expected).


Debian's (with-X) beignet has that string and a few more (__cxx11, 
x11_display, x11_screen, x11_dpy).


Did you do the no-X compile by an explicit option, or by not installing 
the X headers (libx11-dev, libxext-dev, libxfixes-dev)?


Which clinfo is this (there are at least 3 implementations), and can you 
get a backtrace of the error (gdb clinfo)?


beignet doesn't need any kernel patches on recent kernels (>=4.2; check 
with uname -r), and in the known cases where it does, the error is 
"Beignet: self-test failed" not yours.
