The following sections provide some additional details on three of the events.
Dword
Matcher
Dword Matcher is a dword pattern matcher that presents match and mask fields and a
K-Code Mask field. K-Codes are control characters that are always used in the first byte
of a four-byte primitive. Of the K-Code masks listed in the menu, D-D-D-D is used for
data bytes, and K-D-D-D is used for all primitives.
When you create a dword match, keep the following in mind:
•
The pattern can be inside or outside of frames (it does not matter if the pattern
is inside a frame or not)
•
Because the pattern can be inside or outside of frames, there is no offset.
•
You can make user-defined primitives. (This is the reason this feature was
created.)
•
You can use any K/D pattern.
SAS Data
Pattern
When you create a SAS data pattern, keep the following in mind:
•
The pattern must be defined inside a frame that starts with a SOF or SOAF.
•
The pattern must be data only (no K-codes/primitives).
•
The pattern must be defined at a specific offset in the frame.
•
The pattern and mask must be specified in the same format as specified in
the SAS standard.
•
0x12345678 (hex), where "1" is the first digit on the cable and is the MSB as
given in the SAS Standard.
For example, for an SMP Request:
Pattern: 0x40000000
Mask: 0xFF000000
Offset: 0
SOF Type: SOF
SATA Data
Pattern
When you create a SATA data pattern, keep the following in mind:
•
The pattern must be defined inside a frame that starts with a SATA_SOF
•
Must be data only (no K-codes/primitives)
•
Must be defined at a specific offset in the frame
• The pattern and mask must be specified in the same format as specified in
the SATA Standard.
For example, for Register H -> D FIS:
Pattern: 0x00000027
Mask: 0x000000FF
Offset: 0
SOF Type: SATA_SOF
