GPU-g is gpu sharing or cutting?

Hi ACRN community,

 

As I got reply last time from the community, that by using the gvt-g, we CAN NOT assign the e.g. 60 % GPU to uos.

Now I have another question is about the theory of GVT-G,

If I use the gvt-g with parameter -G "10 128 6"  to launch UOS0,

my question is that the other UOS such as UOS1 can access this part GPU or not? Or more especially, the gvt-g will “cut” the GPU or just doing the GPU-sharing?

1.       “cut” means that if we assign this part to UOS0,  and other UOS CAN not  access this part

2.       “sharing” means that other UOS can share the GPU with UOS0 in the same GPU memory.

 

Thank you for your reply in advanced.

Cheers,

Jianjie Lin
