Context Invalidation Request Granularity (CIRG)
Software provides the requested invalidation granularity
through this field when setting the ICC field.
Following are the encodings for the CIRG field:
00: Reserved.
01: Global Invalidation request.
10: Domain-selective invalidation request. The target
domain-id must be specified in the DID field.
11: Device-selective invalidation request. The target
source-id(s) must be specified through the SID and FM
fields, and the domain-id (that was programmed in the
context-entry for these device(s)) must be provided in the
DID field.
Hardware implementations may process an invalidation
request by performing invalidation at a coarser granularity
than requested. Hardware indicates completion of the
invalidation request by clearing the ICC field. At this time,
hardware also indicates the granularity at which the actual
invalidation was performed through the CAIG field.
Context Actual Invalidation Granularity (CAIG)
Hardware reports the granularity at which an invalidation
request was processed through the CAIG field at the time
of reporting invalidation completion (by clearing the ICC
field).
The following are the encodings for the CAIG field:
00: Reserved.
01: Global Invalidation performed. This could be in
response to a global, domain-selective or device-selective
invalidation request.
10: Domain-selective invalidation performed using the
domain-id specified by software in the DID field. This could
be in response to a domain-selective or device-selective
invalidation request.
11: Device-selective invalidation performed using the
source-id and domain-id specified by software in the SID
and FM fields. This can only be in response to a device-
selective invalidation request.
