Preliminary

The following linux command line options are available.

This defines the mask of CPUs in hex that run Linux. Any valid mask can be given 

here and Linux will run on those CPUs. The remaining CPUS can be used for 

RMIOS applications. The default Linux CPU mask is ffffffff 

This defines the start of physical memory in KSEG0 region to use for loading KSEG0 

apps. This address must be: 

•

Greater than _end

•

Multiple of 2MB

•

Less than 0x10000000 

This defines the size of KSEG0 region in hex (no 0x prefix). The user must ensure 

that enough memory has been reserved for Linux to run while configuring memory 

size for the loader. 

The following command options and text use the term “CPU” is 

used for legacy reasons, in most circles “thread” is a more term in 

this application.

Applications cannot be launched on a core that has Linux running 

on a few threads unless the "shared_core" option is passed during 

the kernel boot. 

For example, linux_cpu_mask=0x3f, loader feature will be available 

only on 0xffffff00 CPUs.

Currently if kseg0_start and kseg0_size value are changed below 

the default values mentioned above then loader may fail to launch 

any kseg applications.
