Hi,
current definition of vcpu_match_tr_entry is:
#define vcpu_match_tr_entry(_trp,_ifa,_rid) \
((_trp->p && (_trp->rid==_rid) && (_ifa >= _trp->vadr) && \
(_ifa < (_trp->vadr + (1L<< _trp->ps)) - 1)))
^^
Why -1 ?
I suppose it is either <= (vadr + ps -1) or < (vadr + ps - 1) ?
Thank you for any comment.
Tristan.
