Hi Yusuf,
> 0001f000
Exactly as I thought. The hardware does support BAR resize, but
unfortunately 256MB is already the minimum.
Sorry, but there isn't anything I could do from the GPU drivers point of
view.
The only good news I have is that 256M+2M+512K+128K=260M address space
should be enough for the GPU to work, maybe that makes things a bit simpler.
But you definitely got an interesting use case here :)
Regards,
Christian.
