Context Actual Invalidation Granularity (CAIG)
Hardware reports the granularity at which an invalidation request
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 this field:
00 = Reserved.
01 = Global Invalidation performed. This could be in response to
The following are the encodings for this 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.

Function Mask (FM)
Software may use the Function Mask to perform device-selective
Software may use the Function Mask to perform device-selective
invalidations on behalf of devices supporting PCI Express
Phantom Functions.
This field specifies which bits of the function number portion
This field specifies which bits of the function number portion
(least significant three bits) of the SID field to mask when
performing device-selective invalidations. The following
encodings are defined for this field:
00 = No bits in the SID field masked.
01 = Mask most significant bit of function number in the SID
00 = No bits in the SID field masked.
01 = Mask most significant bit of function number in the SID
field.
10 = Mask two most significant bit of function number in the SID
field.
11 = Mask all three bits of function number in the SID field.
The context-entries corresponding to all the source-ids specified
The context-entries corresponding to all the source-ids specified
through the FM and SID fields must have to the domain-id
specified in the DID field.

This field indicates the source-id of the device whose
corresponding context-entry needs to be selectively invalidated.
This field along with the FM field must be programmed by
software for device-selective invalidation requests.

Domain-ID (DID)

This field indicates the id of the domain whose context-entries
need to be selectively invalidated. This field must be
programmed by software for both domain-selective and device-
selective invalidation requests.
The Capability register reports the domain-id width supported by
The Capability register reports the domain-id width supported by
hardware. Software must ensure that the value written to this
field is within this limit. Hardware may ignore and not implement
bits15:N, where N is the supported domain-id width reported in
the Capability register.
