[win-pv-devel] XcGnttabMapForeignPages function fails

[Gaurav Khuntale <gauravkhuntale@xxxxxxxxx>]

Hello Folks,

For learning purpose i am trying things with event-channel and grant pages on Xen.

The problem currently i am facing is, XcGnttabMapForeignPages() function fails to map grant pages which are shared from domain 0 with error code as 31(0x1f). To share pages from domain 0, i am using xc_gntshr_share_pages() function.

When i tried to map grant pages into the windows guest domain which are shared from other windows guest domain then same function XcGnttabMapForeignPages() works perfectly.

Can anyone please help me to understand why i am observing such a behavior? Does grant page sharing not supported across the different operating system?

Thanks in advance.
