Cryptographic Coprocessor Timing (Subtype 20)

ICSF periodically records processing times for coprocessor or accelerator operations in subtype 20. Subtype 20 contains this information:

• The device type
• The time immediately before the operation begins
• The time immediately after the operation ends
• The time immediately after the results of the operation have been communicated to the caller address space
• The number of processes waiting to submit work to the same coprocessor, domain, and reference slot used by this operation
• The function code for this operation
• The coprocessor or accelerator processor number
• The coprocessor or accelerator serial number
• The coprocessor or accelerator domain
• A reference number that identifies an internal ICSF queue element
