memtest
If you issue a Ctrl/C or the kill command with a PID in the middle of testing,
the process might not abort right away. To increase speed of execution,
memtest
check for a Ctrl/C or kill command done outside of any test loops. If this is not
satisfactory, you can run concurrent
shorter lengths within the target range.
Syntax
memtest [-sa start_address ] [-ea end_address ] [-l length ]
[-bs block_size ] [-i address_inc ] [-p pass_count ]
[-d data_pattern ] [-rs random_seed ] [-rb]
[-f] [-m] [-z] [-h] [-mb] [-t] [-g] [-se]
Options
-sa start_address
Specifies the starting address for the test. The default is the first free space in
the memory zone.
-ea end_address
Specifies the ending address for the test. The default is start_address plus length.
-l length
Specifies the length of the section to test in bytes. The default is BLOCK_SIZE,
except with the -rb option,which uses the zone size. The -l option has precedence
over the -ea option.
-bs block_size
Specifies the block size (hexadecimal) in bytes. The default is 8192 bytes. This
is only used for the random block test. For all other tests, the block size equals
length.
-i address_inc
This value is used to increment through the memory to be tested. Default = 0
(no increment). This is only implemented for the graycode test. The increment
value is in quadwords (that is, increment of 1 tests every other quadword). The
-z option must be specified to test an unaligned starting address. This option is
useful for multiple CPUs testing the same physical memory.
-d data_pattern
This pattern is used as a test pattern. The default is 5s.
-p pass_count
Specifies the number of times to execute the test. If you specify 0, the command
runs forever or until you enter Ctrl/C. The default is 1.
