Hi,

Is there an API kernel exposes to use for a driver in order to reserve physical address space?

I mean I want to reserve 5GB (or more if allowed) of contiguous physical address space anywhere in the address range (wherever it is available.. doesn't matter) and then I want to map that physical address range in the kernel to get a virtual address so that my driver can dereference that virtual pointer to access the mapped physical address range.

Thanks in advance!
