Hello!
I’m not sure if this is the right forum, since I will eventually be using the GPU solely for computation, but at this point I’m having trouble even running the CUDA examples, and the error strikes me more as a Linux question than a computation-specific one. I apologize if this lands in the wrong place!
I’m running headless on a Linaro build of Ubuntu 14.04, with a 3.13 kernel specifically built for the Xilinx Zynq-7000, on an avnet mini-ITX board: Avnet: Quality Electronic Components & Services
The Zynq-7000 is an FPGA married to two ARM Cortex A9 cores aka armv7/armhf. I’ve got a GTX 660 Ti in the single PCIe 4x slot, and I can see it on the PCIe bus using lspci:
root@linaro-developer:~# lspci
00:00.0 PCI bridge: Xilinx Corporation Device 0706
01:00.0 VGA compatible controller: NVIDIA Corporation GK104 [GeForce GTX 660 Ti] (rev a1)
I have the CUDA toolkit 6.5 installed from this link: http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1404/armhf/cuda-repo-ubuntu1404_6.5-14_armhf.deb
I have the nvidia-340 driver installed via ‘apt-get install nvidia-340’. During that installation, the module built against the natively-built kernel source successfully.
For the CUDA samples, I cross-built them from a Ubuntu 14.04 x64 machine; they built successfully there, but when I attempt to run the matrixMul sample program (a program I was confident wouldn’t balk at the lack of an X server), I get this in dmesg:
[ 3259.872635] NVRM: Can’t find an IRQ for your NVIDIA card!
[ 3259.872636] NVRM: Please check your BIOS settings.

[ 3259.872641] NVRM: None of the NVIDIA graphics adapters were initialized!
[ 3259.872643] NVRM: NVIDIA init module failed!
On an Intel system with a BIOS, I would know where to go with this, but on an ARM I’m less certain. Here is my device tree entry for the PCIe bus:

I’m comfortable trying or changing anything that needs to be done to get this to work, including kernel configuration, device tree, etc, if anyone has any suggestions. Any help is much appreciated!
