The one that you know better...

The only thing keeping me from using linux is there is no 1080p 71.928 for crt to push out raster ringing
on the projector. I prefer it over Windows pq wise.

Is there a way to enable this resolution in Linux? And all the timings that works so well with windows.

Thanks Greg

Have a look at the xrandr utility, more specifically the --addmode argument: https://wiki.ubuntu.com/X/Config/Resolution

Digging a bit deeper into this I ran LuxMark 3.1 (downloaded from here: http://www.luxrender.net/wiki/LuxMark#Download) just to see if things were working. The GPU only gets about 2x-3x the speed of the CPU in the render benchmark, but it's only an A8-5545M anyway so I wasn't expecting more than that. Checking with ldd and /proc/<PID>/maps against SVPManager I get the exact same libraries being used by LuxMark.bin . Do you by any chance have an AMD card to test with?

hmm... this's interesting big_smile

I meant as in it detects a device with the expected name string at gpuID=11, but yes, this is why I'm having a hard time understanding why it doesn't work. If the "cl_khr_fp64" extension doesn't exist then an OpenCL kernel explicitly declaring it should simply fail to compile, right?

The thing that confuses me the most is that even with gpuID=21, which should be the CPU based device and totally supports both "cl_khr_fp64" and "cl_amd_fp64", SVPManager still fails to init OpenCL.

Perhaps I just need some sleep. The error could well be starring me right in the face, but I'm not seeing it.

This's not the case.
clGetPlatformIDs() call for some reason fails in both SVPManager and svpflow lib, BUT it works in clinfo.
The only difference is clinfo is linked with libOpenCL.so while SVPManager loads it dynamically at runtime.

Could it be that you have several different versions of libOpenCL.so installed?

In other words check that libOpenCL.so from "ldd clinfo" and the one from /proc/<SVPManager pid>/maps point to the same AMD's .so file.

It seems like they do:

This also confirms SVPManager is correctly using the x86_64 version of the library. I did notice however that entering a bogus value into the GPU ID field (such as "55") does not change the error message at all. Shouldn't it? I would had expected at least a change in the line number that "vapoursynth.c" errors out in the traceback (nonexistent device vs possibly unsupported implementation).

Edit: I can't get this to make sense at all actually, OpenCL can init the GPU just fine with other tools and although quirky it does work with slight modifications to the previously mentioned demo code. Yet it doesn't work at all when SVPManager tries to use it, despite evidently detecting the correct OpenCL device:

Oh, I see now. I must have read the names wrong (there was A LOT of debugging to get OpenCL running).

If I try to play a file after enabling OpenCL I get a crash. I'm unable to retrieve the event log, but this is what appears on the command line:

It works fine if I disable OpenCL (by moving /etc/OpenCL/vendors/amdocl64.icd to /etc/OpenCL/vendors/amdocl64.icd.bak). I'm starting to think there's something wrong with the OpenCL implementation itself.

Mid-post update: I tried to run the testing tools (from https://github.com/hpc12/tools) again with the proper OpenCL device (derp) and found that selecting the GPU throws this error:

*** build of 'sum' on 'Devastator' said:
"/tmp/OCLWqA90x.cl", line 1: error: can't enable all OpenCL extensions or
          unrecognized OpenCL extension
  #pragma OPENCL EXTENSION cl_khr_fp64: enable
                           ^

1 error detected in the compilation of "/tmp/OCLWqA90x.cl".

Frontend phase failed compilation.

*** (end of message)
*** 'clBuildProgram' in 'cl-helper.c' on line 470 failed with error 'build program failure'.
Aborted (core dumped)

I recall from the output of clinfo that "cl_khr_fp64" is the double type supported on the CPU, the GPU only supports "cl_amd_fp64". From the context I guess "khr" refers to Khronos? If so I think this means my GPU doesn't support standard double types in OpenCL. sad

Armed with this theory I ran the following in the tools directory:

sed -i 's/cl_khr_fp64/cl_amd_fp64/' vec-add-soln.cl

Then I recompiled the tools with 

make clean
make OPENCL_INC="/opt/AMDAPP/include/"

I then ran the cl-demo tool again, which terminated with this message:

*** Kernel compilation resulted in non-empty log message.
*** Set environment variable CL_HELPER_PRINT_COMPILER_OUTPUT=1 to see more.
*** NOTE: this may include compiler warnings and other important messages
***   about your code.
*** Set CL_HELPER_NO_COMPILER_OUTPUT_NAG=1 to disable this message.

GOOD

So in short, my GPU is weird but now I know about it and I can, in theory, fix it! smile

Hopefully newer AMD GPUs supports the Khronos extensions, but it seems it's as simple (it's never simple) as replacing "cl_khr_fp64" with "cl_amd_fp64". From my extremely limited testing they seem to behave close enough to be compatible.

I'm sorry it turned into such a lengthy post, but I really hope any of this information helps smile

gpuId=11 in this context means "1st GPU device on the 1st platform", so what's wrong?

more interesting is the actual Vapoursynth error (if any) when the filter script initialization fails

The first device is a virtual device, the second is the actual GPU. I think AMD did this for compatibility reasons (the CPU will always exists while an AMD GPU may not). I have tried entering both "12" and "21" into the GPU ID field but it still gets reset to 11. Furthermore even the CPU-based OpenCL render seems to fail, which is odd considering other OpenCL code works (including the SVP4 clinfo utility). Can you post a sample output of what this should look like with working OpenCL?


Regarding Vapoursynth, I've found on Ubuntu 14.04 that APT wants to pull mpv from the SMPlayer repo which doesn't have Vapoursynth support, this is how I fixed it:

sudo apt-get install mpv=1:0.15.0-1~trusty
sudo apt-mark hold mpv

This will force the (currently) latest version of mpv from ppa:djcj/vapoursynth . This is because the mpv version from ppa:rvm/smplayer is prefixed with "2:" which in turn makes APT prefer that version. It's probably a repo-side hack to prevent the official repo from upgrading over the PPA version from rvm, which in our case also replaces the PPA version from djcj. For a more permanent solution I would reccomend APT pinning, but this works as a temporary solution to verify the correct version is installed.

I'm not sure if this is the error you're referring to, but I thought it might at least help someone.

I think I may have found a bug; SVPManager insists on using gpuID=11 regardless of what the actual configured value is, which completely breaks the OpenCL support.

I have tried changing the GPU ID the advanced settings to no avail, whatever I put in there it gets replaced with 11. I even tried manually editing ~/.local/share/SVP4/settings/frc.cfg against all advice but it still insisted on using gpuID=11.

Aside from that SVP 4 works great (a bit slow without OpenCL on an A8-5545M though) smile
