Hi,
Is there a way to map a non-page aligned kernel physical address to user virtual address? remap_pfn_range and vm_insert_page operate only on page-aligned physical addresses.
If there is no such support, would it be too complicated to try out writing something on my own to map non-page aligned addresses (the data size is under my control - so I can make that a multiple of page size)?
Any suggestions appreciated.
Thanks -- Vira
