[Xen-devel] built-in log mechanism for pending messages

[Kerti Csaba <csocskos@xxxxxxxxxxx>]

Dear Developer mail-list members!
 
I like to interest, that is there any built-in log mechanism which is contains 
how many pending messages has each domain (including dom0)?
(I like to reach this information from the do_schedule() method from the 
scheduler)


 
Actually I’m reading “The Definition Guide to the Xen Hypervisor” book, and I 
found the following information there:
“The evtchn_pending of the shared_info_t is 8 machine words long and contains a 
bit-field which event channels have events waiting.”

If I calculate that, how many bits sets to 1 on the evtchn_pending field, then 
I get the number of pending messages for a domain? Is this also works for 
dom0(incoming/outgoing pending massages)?
 
Thank you in advance
Csaba
