OpenCL

[pdxtabs]

Hello,

I just got an AMD Vega Frontier Edition, which is my first AMD OpenCL enabled card. As such, I sort of don't know what I am doing. I performed the following actions:

1. Installed a fresh copy of Ubuntu 16.04.2 with all updates, rebooted.
2. Installed "Radeon Vega Frontier Edition for Ubuntu 16.04.2 17.6" driver (amdgpu-pro-17.20-445420.tar.xz), rebooted.
3. Installed APP-SDK 3.0.130 (AMD-APP-SDKInstaller-v3.0.130.136-GA-linux64.tar.bz2), rebooted.

However, when I run clinfo (or sudo clinfo) it crashes:

$ sudo clinfo

terminate called after throwing an instance of 'cl::Error'

  what():  clGetPlatformIDs

Aborted (core dumped)

Did I miss a step?

My system is as follows:

• AMD Graphics Card
  • AMD Graphics Card: Vega Frontier Edition
• Desktop or Laptop System
  • Desktop
• Operating System
  • Ubuntu 16.04.2, with all updates
• Driver version installed
  • "Radeon Vega Frontier Edition for Ubuntu 16.04.2 17.6" driver (amdgpu-pro-17.20-445420.tar.xz)
• Display Devices
  • Dell U2413f, DVI (with adapter from Frontier Edition box), 1920x1200 @ 60Hz
• Motherboard + Bios Revision
  • MSI B75MA-P45 BIOS 1.9 (latest)
    
• CPU/APU
  • Intel i5-3470
    
• Power Supply Unit  Make, Model & Wattage
  • EVGA SuperNOVA 1000 G2
• RAM
  • 8GB

I have attached a full dmesg, strace of clinfo, and the coredump of clinfo.

Adding strace.

Can you please do a system check?

System Check
The easiest way to find out if you have AMDGPU-Pro already installed on your Ubuntu System is to query the Debian package manager.

Using the following command at a terminal will provide you with the version of the AMDGPU-Pro stack on your system, or inform you that there are no packages found:

dpkg -l amdgpu-pro

[pdxtabs]

Okay, I'm not sure how to interpret this:

$ dpkg -l amdgpu-pro

Desired=Unknown/Install/Remove/Purge/Hold

| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend

|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)

For the Frontier Edtion version of OpenCL, you do not need to install OpenCL SDK 3.0 to do development.    You should not install, what it did is over write the correct path to where the OpenCL components are which is causing the crash

Configuring the environment

The LLVM_BIN environment variable needs to be set prior to running applications that require OpenCL.

Set it permanently in bash, for all users:

echo 'export LLVM_BIN=/opt/amdgpu-pro/bin' | sudo tee /etc/profile.d/amdgpu-pro.sh

Set it permanently in csh, for all users:

echo 'setenv LLVM_BIN /opt/amdgpu-pro/bin' | sudo tee /etc/profile.d/amdgpu-pro.csh

Please see this blog how best to install the driver

This blog post? http://gpuopen.com/vega-frontier-installing-the-driver/

[gstoner]

Yes this is the post.

I wiped and reloaded my Ubuntu 16.04.2 installation and followed the instruction in the blog post:

​tar -Jxvf amdgpu-pro-17.20-445420.tar.xz

cd amdgpu-pro-17.20-445420

./amdgpu-pro-install -y

sudo apt install -y rocm-amdgpu-pro

echo 'export LLVM_BIN=/opt/amdgpu-pro/bin' | sudo tee /etc/profile.d/amdgpu-pro.sh

echo 'setenv LLVM_BIN /opt/amdgpu-pro/bin' | sudo tee /etc/profile.d/amdgpu-pro.csh

sudo reboot

However, even though I have amdgpu-pro and rocm-amdgpu-pr installed and LLVM_BIN set correctly, clinfo still crashes:

$ dpkg -l amdgpu-pro

Desired=Unknown/Install/Remove/Purge/Hold

glxgears and glxinfo work fine. I have attached the output from glxinfo.

If someone at AMD would like to debug on my hardware, you are welcome to borrow it.

[gstoner]

Did you try typing sudo ./clinfo

Do not install the APP-SDK 3.0.130 it also installs OpenCL Headers which overwrite the correct headers.

[pdxtabs]

I did not install the APP-SDK after a clean install of Ubuntu 16.04.2 (with all Ubuntu updates).

$ cd /opt/amdgpu-pro/bin/

$ sudo ./clinfo

[sudo] password for XXXXX:

I started this thread 9 days ago. Should I open a support case? Will I get better support? Do you want to borrow my hardware?
