[PATCH v4 11/11] pnv/xive2: Dump more END state with 'info pic'
Posted by Michael Kowal 1 year, 6 months ago 
From: Frederic Barrat <fbarrat@linux.ibm.com>

Additional END state 'info pic' information as added.  The 'ignore',
'crowd' and 'precluded escalation control' bits of an Event Notification
Descriptor are all used when delivering an interrupt targeting a VP-group
or crowd.
