Test Group 5502
Device Processor
This group tests the processor or processors. The tests confirm the correct operation of both the base, or core, behaviour and the various instruction set extensions supported such as SSE.
The tests are designed to look for anomalous behaviour while processing test sequences and data that are assembled on the fly. The testing approach ensures availability of all register and instruction combinations using a large volume of test data against a model for the expected behaviour. There are tests for the integer and floating point instructions, plus tests for vector instructions.
The group also includes tests for symmetric behaviour, such as ensuring cores execute at similar speeds or that local cache content can remain synchronised during heavy loading from all cores.
Note: Each device identified by this group represents a physical processor package (socket).
Note: Each set of tests when selected are executed on every applicable processor core / hardware thread (SMT).
Test Number 401
Test Name Core Instruction Set
This test performs certain CPU operations and checks the results against expected results. The CPU Test is made up of the following categories:
General: Loads registers with patterns, performs operations that affect certain flags, and then checks to see that everything is operating correctly.
Arithmetic: Performs various addition, subtraction, multiplication, and division operations and verifies against expected results.
Logic: Tests shift and rotate instructions.
PARAM1: Test bootstrap processor only
Test only the bootstrap CPU thread.
ERRORCODES & TROUBLESHOOTING
