memtest
The memtest command tests a memory range.
Format
memtest [iterations [start_address [end_address [increment [mcheck [stop_drivers]]]]]]
Parameters
iterations
Specifies the number of times the memory range test will run. The default iteration
is 1.
start_address
Specifies the address at which to start the memory test. The default is the current
address.
end_address
Specifies the address at which to end the memory test.
increment
Defines the step size. The default is longword access (4).
mcheck
Specifies the machine check state as defined by the mcheck command (see the
mcheck command). The mcheck state is specified during the start of the memory
test. Possible selections are: on, off, cpu, and system. The default is on.
stop_drivers
Specifies if device drivers should be stopped before the start of the memory test. A
nonzero value stops all device drivers. A zero value specifies that drivers should not
be stopped. The default is stopped.
Description
The memtest command performs a set of memory tests on the specified address
range. This test uses longword accesses to memory. The tests include walking 1s and
walking 0s as well as alternating 1s and 0s.
