Enduro laptop with 7670M + Intel HD 4000. Win8 64-bit. Tried official laptop driver, and latest AMD mobility driver 13.251.0.0 (amd tool installed this one).
Only iGPU -> iGPU surfaces sharing works. iGPU -> dGPU, dGPU -> iGPU, dGPU -> dGPU STILL DOES NOT WORK!
Please note, the only way to understand that surface sharing doesn't work is to get failed result of OpenSharedResource method call (which returns success). CopyResource and other methods that may use shared resource have no return value!
So I will mention again, OpenSharedResource must FAIL ELSE surface sharing must WORK.
DO ANYONE HERE FROM AMD READ THIS FORUM? DO YOU PLAN TO FIX THIS VERY IMPORTANT BUG?
I hope that everyone here understand that with html5 even browsers today uses d3d hardware acceleration and uses surfaces sharing functionality between processes. These bugs is not acceptable at all.
