; TCO 6.1.1342 - Add UNEXI and NU.CXI.
; UPD ID= 1423, SNARK:<6.1.MONITOR>NIPAR.MAC.7, 29-Jan-85 14:36:05 by GROSSMAN
; TCO 6.1.1162 - Add state UNS.RR - Reload Requested. Also, ensure proper
; mapping between UNS.xx states and .EISxx states defined in MONSYM.
; UPD ID= 1185, SNARK:<6.1.MONITOR>NIPAR.MAC.6, 11-Dec-84 14:40:00 by GROSSMAN
; TCO 6.1.1080 - Define bits for send/receive failure bit masks.
; UPD ID= 1049, SNARK:<6.1.MONITOR>NIPAR.MAC.5, 13-Nov-84 00:22:18 by GROSSMAN
; TCO 6.1.1048 - Decrease all state symbols by 1 so that they match up with
; NI% state symbols in MONSYM. Also, make all definitions in this module
; be global. Redefine TABBEG,TABENT and friends so that they can accept
; arguments that expand into multiple lines of macro.
; UPD ID= 754, SNARK:<6.1.MONITOR>NIPAR.MAC.3, 24-Aug-84 11:37:26 by GROSSMAN
; Add UNICS%.
; UPD ID= 693, SNARK:<6.1.MONITOR>NIPAR.MAC.2, 18-Jul-84 10:13:30 by GROSSMAN
; Add missing transmit error codes.

SUBTTL LLMOP PSI queue
COMMENT $
Nota bene - Once upon a time, LLMOP did some nasty things. It called
PSIRQ at interrupt level. This caused GLFNF BUGHLTs, SUMNR1 BUGCHKs,
and UNBFNF BUGCHKs. This is not good. So now, there is a queue for
LLMOP to queue up PSI requests. It looks something like this:
LLMPSQ/ ENTRY1 ------>+
|
+----> ENTRY1+.FLPSI/ Pointer to next entry ---...
ENTRY1+.CHNFK/ channel,,fork
LLMOP PSI queue entry
+--------------------------------------------------+
.FLPSI | Forward pointer to the next entry in the queue |
+--------------------------------------------------+
.CHNFK | Channel number for PSI | Fork number to get PSI |
+--------------------------------------------------+
