incorrect number of opencl platforms...

Hi,

I have a system with  phenom x4 CPU and 2xHD5970 cards.

In other threat (http://forums.amd.com/devforum/messageview.cfm?catid=390&threadid=134757&highlight_key=y) I found that in WinXP32 without crossfire enabled, I see 4 opencl platforms (1 CPU + 3 GPU) and if I disable crossfire, I see the correct number (1CPU + 4GPU).In linux x86_64 (OpenSuse 11.2) I see 1CPU + 4GPU with crossfire disabled.

Now I upgraded to SDK2.2 + cat10.7 update driver (the one in AtiStream SDK page). In WinXP32 without crossfire enabled, I see 1CPU + 3GPU as before, but if I enable crossfire; clinfo shows 6 platforms, 1CPU + 5GPU, cal findnumdevices shows 5 devices, and simplemultidevice -e tells me that CPU0 + GPU0 to GPU4 passed the tests.

Did someone see something similar? Has virtualization arrived? Thanks in advance for any insight about this.

best regards,

Alfonso
