Hi all,

While I was trying to track to find out how a device alloc a new memory resource, I have been little confused on finding out how the new PCI device can deal with a case when the activation calls pmap_mapdev????

What I need to understand that what will happen if pmap_mapdev allocated a new space that dose not match what is expected by the device and determined by r_start and r_end ??

Yours,
