Hello,
Thanks for the reply. My question is as follows
I am having multicore system with total 4GB RAM . I am running Linux on
one core and other RMIOS application on the other cores. Since Linux is using
all 4GB total physical RAM, I want to restrict this physical RAM from 4GB to 2GB,
so that Linux should use only 2GB out of 4GB so that
I can run my RMIOS application on other 2GB physical RAM
(NOTE: Linux should not interfere with other 2GB RAM which my application is using)
Please answer my query and thanks in advance.
Hemanth

Hemanth,
You can set a hard memory limit with the mem= kernel parameter.
see here:
