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?
