Unable to generate 'GPA' data with my Intel HD Graphics 4000
I'm trying to profile the execution of an OpenCL kernel on Intel HD Graphics 4000. I've installed the 30-day trial of both VTune and INDE.
If I right-click on my Project in VS2013 > Intel VTune Amplifier XE 2015 > New Analysis, I see this message in the window that opens:
Some GPU metrics are currently disabled by the BIOS. See the product Release Notes for details.
I've attached two images: one showing the tick-box for GPAs in my motherboard BIOS (it's not clear in the image, but the box seems to be greyed-out, and I'm unable to tick it), and another showing the results of a VTune analysis run of my program, showing zero L3 cache misses, which I presume means the GPAs are not working.
