CPU Node [0] has no GPU connected

First, congratulations on the 1.3 release.

Not sure what you did but my GNOME openbox desktop is working again.

Using the new 4.6 kernel, and much the same setup as the 1.2 setup for clang_tot_upgrade branch, I am having difficulty running the saxpy example.

hcc $(hcc-config --ldflags --cxxflags) -o sax saxpy.cpp -g3
LD_LIBRARY_PATH=/opt/rocm/lib ./sax
CPU Node [0] has no GPU connected
Segmentation fault

Can you try running hsa sample in /opt/rocm/hsa/sample ?

LD_LIBRARY_PATH=/opt/rocm/lib ./vector_copy

Can you paste in uname -a ?

Seems like a runtime issue. Can you create an issue here[1]?

Looks like you didn't install the kernel from AMD? Mine shows:

Linux d7e13bb11ac9 4.6.0-kfd-compute-rocm-rel-1.3-63 #1 SMP Fri Oct 28 13:14:45 CDT 2016 x86_64 x86_64 x86_64 GNU/Linux

I built https://github.com/RadeonOpenCompute/ROCK-Kernel-Driver/tree/roc-1.3.x so I would imagine it's right.

I don't think this is related to the hcc compiler at this point. Do you mind opening a ticket against RadeonOpenCompute/ROCm so that the driver and runtime guys could respond to it? Thanks.

[PhilipDeegan]

I've already opened up a ticket on runtime, rather not be spamming tickets tbh

to be investigated by the runtime ROCm/ROCR-Runtime#17
