-rs random_seed
Specifies the random seed. Use this option only with the -rb option. The default
is 0.
-rb
Specifies to randomly allocate and test all of the specified memory address range.
Allocations are done of block_size.
-f
Specifies fast mode. If you specify -f, the data comparison is omitted. Only ECC
/EDC errors are detected.
-m
Specifies that the memory test is to be timed. At the end of the test, the elapsed
time is displayed. By default, the timer is off.
-z
Specifies that the test is to use the specified memory address without an
allocation. This bypasses all checking, but allows testing in addresses outside of
the main memory heap. It also allows unaligned testing.
This flag permits testing and corrupting any memory!
-h
Allocates test memory from the firmware heap.
-mb
Uses memory barriers after each memory access. Use this option only in the -f
graycode test. When this flag is specified, an Alpha MB instruction is executed
after every memory access, which guarantees serial access to memory.
-t
Specifies the tests to run. By default, all the tests in the selected group are run.
The individual tests are as follows:
1 Graycode test
2 March test
3 Random test
4 Victim eject test
