Many of the ST system-on-chip devices have multiple CPUs, where a
|
||
|
|
master CPU running Linux has control over a number of slave CPUs,
|
||
|
|
which are usually used to run dedicated algorithms.
|
||
|
|
Enabling this option will add support to the Linux kernel to
|
||
|
|
control these slave CPUs, reserve memory for them, and thus allow
|
||
|
|
code to be downloaded onto them and executed.
|
||
|
|
Adding in the command line the following string:
|
||
|
|
coprocessor_mem=[offset]:size0[,size1][,size2]...
|
||
|
|
where:
|
||
|
|
offset defines where the co-processors region starts.
|
||
|
|
It's an offset from ST40 RAM start.
|
||
|
|
size{n} defines the region size for the n.th slave core (max 16M).
|
||
|
