I have some question.
I heard HD graphic takes memory from the system RAM.
Opengl needs to copy pages to run on GPU from host memory to device memory(graphic memory in system RAM).
who copy pages ? kernel or device driver?
I couldn't find where pages are copied from host memory to device memory.
Hi Husung, the amount of memory allocated by DVMT will be exclusively used for Intel® HD Graphics; the operating system will not have access to it.
