[Beignet] How to find/enable a PC supported by libxcam?

[Zhang Fan]

Dear Beignet Experts,

I built and ran Intel's libxcam on several PCs, but all failed as below
./test-cl-image -t retinex -f NV12 -i ./input.nv -o ./output.nv -W 512 -H 512

DRM_IOCTL_I915_GEM_APERTURE failed: Invalid argument
Assuming 131072kB available aperture size.
May lead to reduced performance or incorrect rendering.
get chip id failed: -1 [22]
param: 4, val: 0

The "pciid" of my PCs include 191f and 0e00, got from: pciid=($(lspci -nn | grep "\[8086:.*\]" -o | awk -F : '{print $2}' | awk -F ] '{print $1}'))
I wonder whether you can make my PCs supported by Project libxcam?

More details about my issue can be found at: https://github.com/01org/libxcam/issues/449
