===/proc/virtual/info===
===/proc/virtual/<xid>===
This directory contains several files which can provide valuable information on the current context state and settings.
==== /proc/virtual/<xid>/info ====
ID: 1001
Info: 83c37000
Init: 0

this shows the context id, vx_info location and init pid
==== /proc/virtual/<xid>/status ====
UseCnt: 38
Tasks: 16
Flags: 0000000000000000
BCaps: 00000000d46c04ff
CCaps: 0000000000000000
Ticks: 0

this contains the usage count (references) and task count, as well as the context flags, capability boundary and context capabilities
==== /proc/virtual/<xid>/sched ====
Token: 0
FillRate: 1
Interval: 4
TokensMin: 6
TokensMax: 50
PrioBias: 0
VaVaVoom: 0
cpu 0: 0 0 0
shows the current amount of tokens, scheduler parameters (fill rate, interval, min/max), the priority bias and the calculated vavavoom (priority bonus)

==== /proc/virtual/<xid>/cacct ====
UNSPEC: 0/0 0/0 0/0
UNIX: 35/2375 35/2375 0/0
