[Xen-devel] __vmap multiple times same mfn

[Oleksandr Andrushchenko <andr2000@xxxxxxxxx>]

Hi, all!

I have a use-case when I may need to call __vmap for kernel provided 
IPAs (read MFNs)
which may not be PAGE_SIZE aligned etc.

The question is if it is safe to call __vmap multiple times for 
different IPAs
sharing the same page (mfn), e.g. map something like 6ca00 0080 and 
6ca00 00a0?
Thank you,

Oleksandr
