Hi,
I need to convert a user virtual address to its
corresponding physical address.
I know that if the virtual address is from kernel,
we could use virt_to_phys.
Is there a similar helper function
to convert user virtual address.?
Hi Fredrick,
Please elaborate the purpose,
User-space application allowed to have virtual address upto 3GB, assuming 1:3 address space split.
And its not mandatory for all user-space address to be valid and to have all user-space address to have a valid physical address mapping.
Thanks,
Chetan
