Intel® Iris™ Graphics Extension for instant access for 4th Generation Intel® Core™ processors allows direct access to memory allocated for the GPU. The extension provides a mechanism for specifying which buffers will be shared and locking the memory for reading and writing from CPU side code. This sample demonstrates how to properly access the memory from the CPU to maintain performance with sample code for computing the tiled addressing scheme.
I've been messing around with the new Flip Presentation Model introduced in Windows* 8 (and on Windows* 7, with the Platform Update). I'll have another post soon explaining my ulterior motives for wanting this, but for now here are a few notes on the Flip model that I collected along the way.
For being something new to all of us, doing this Virtual Hackathon last weekend varied between going very smoothly and throwing problems at us that no one expected. Just as everyone put a lot into hacking up project code, a lot went into making the Virtual Hackathon possible.
This was a great hackathon. We learned things we might not have without the hackathon. I know for sure I did. I was never able to setup Apache with PHP in the past because of reasons, but the hackathon had me tackle the problem until it was solved [for the entire 1st day].
