Hi, I've been trying to benchmark two similar programs, one running in the NW and another running in the SW of a i.MX53 QSB. I've adapted the tz_vmm example to run the SW program and the NW program is running on top of Linux.
I compiled my NW program with the -O3 optimization flag and I'm wondering if the code in tz_vmm can also be compiled with this flag in order to have the same optimization flag in both scenarios.
If it's possible, what do I have to change in order to achieve this?
Thanks in advance! Tiago
You can try compiling it by modifying CC_OLEVEL in your <build_dir>/etc/tools.conf (by the default, this file doesn't exist, so you would have to create it):
CC_OLEVEL = -O3
You can verify if it is applied by adding VERBOSE= to your make call:
VERBOSE= make <target>
Cheers, Martin

As supplement: this will change the optimization flag for all Genode components including the kernel. If you want to change it for a component only, add above line into its target.mk file instead of the global <build_dir>/etc/tools.conf file.
