spapr: add hcalls support for the XIVE exploitation interrupt mode
The different XIVE virtualization structures (sources and event queues)
are configured with a set of Hypervisor calls :
- H_INT_GET_SOURCE_INFO
used to obtain the address of the MMIO page of the Event State
Buffer (ESB) entry associated with the source.
- H_INT_SET_SOURCE_CONFIG
assigns a source to a "target".
- H_INT_GET_SOURCE_CONFIG
determines which "target" and "priority" is assigned to a source
- H_INT_GET_QUEUE_INFO
returns the address of the notification management page associated
with the specified "target" and "priority".
- H_INT_SET_QUEUE_CONFIG
sets or resets the event queue for a given "target" and "priority".
It is also used to set the notification configuration associated
with the queue, only unconditional notification is supported for
the moment. Reset is performed with a queue size of 0 and queueing
is disabled in that case.
- H_INT_GET_QUEUE_CONFIG
returns the queue settings for a given "target" and "priority".
- H_INT_RESET
resets all of the guest's internal interrupt structures to their
initial state, losing all configuration set via the hcalls
H_INT_SET_SOURCE_CONFIG and H_INT_SET_QUEUE_CONFIG.
- H_INT_SYNC
issue a synchronisation on a source to make sure all notifications
have reached their queue.
Calls that still need to be addressed :
H_INT_SET_OS_REPORTING_LINE
H_INT_GET_OS_REPORTING_LINE
See the code for more documentation on each hcall.
