Hello Guys, Does memory on Dom0 also mapped to gpfn or it is mapped directly to mfn?
If mapped to gpfn, how can I access its p2m mapping? I'm trying to use the xen-mfndump but it is not working with dom0 ./xen-mfndump dump-p2m 0 xc: error: Could not map the shared info frame (MFN 0xddfe9) (3 = No such process): Internal error xc: error: Could not map domain 0 memory information: Internal error The problem that I'm wanting to solve is: Given a va in a process on dom0, I can get its physical representation (mfn or gpfn depending on how this works on PV) using /proc/pid/pagemap and with this I can access its real mfn. This works perfectly with domU but not with dom0, why? Atenciosamente, *Charles Ferreira Gonçalves *
