NAME¶

vm_iomap_memory - remap memory to userspace

SYNOPSIS¶

int vm_iomap_memory(struct vm_area_struct * vma, phys_addr_t start, unsigned long len);

ARGUMENTS¶

vma

start

len

DESCRIPTION¶

This is a simplified io_remap_pfn_range for common driver use. The driver just needs to give us the physical memory range to be mapped, we´ll figure out the rest from the vma information.

NOTE! Some drivers might want to tweak vma->vm_page_prot first to get whatever write-combining details or similar.
