mfn_x() in Xen

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,

I couldn't find anything related to mfn_x through googling.
Moroever i was unable to find a definition for mfn_x.

it looks like an opaque data type but i doubt as genrally in Xen all
such hiding is done behind *_t typedefs mostly.

This leaves me with few options
Either it is a macro or an inline function.Which sadly i am unable to find :-(.

Only thing i can notice is it is used mostly when we are mapping a
pseudo physical page from a foreign guest domain to get the its actual
mfn.

Does this means it is used to convert between the shadow table's entry
which the guest sees and the actual mfn ?

Another query, pretty stupid though, what is the use of a monitor
table? Is it used for this conversion between shadow table's entry
which guest sees as a mfn and the actual mfn?

I am going through Xen-3.0.3 source.

Can anybody help me with my doubts?

Thank you
