Talos Set up
1) Install the Nginx web server from [1]. I choose Nginx because there is a precompiled version available. If we find that this does not work, we probably can cross-compile apache or lighttpd for testing purposes.
2) Copy talos to /media/mmc2/talos
Remember that on the n810, space is tight. You may have to uncompress the distribution somewhere off the device, then scp it to your device. Or you can just go buy a 8gb card.
3) Make sure that that configure file points to the right places. The important pieces are:
firefox: /root/fennec/fennec process_name: fennec extra_args: ""
4) As root, start nginx:
/usr/sbin/nginx
5) Create a link to the talos page set in /var/www:
ln -s /media/mmc2/talos/page_load_test/ /var/www/page_load_test
6) run talos.
python2.5 run_tests.py sample.config
Known Issues
Note that you must use the [patch https://bugzilla.mozilla.org/show_bug.cgi?id=426444]. Soon this should just be part of the standard talos install.
I have found that I needed to increase the |sleep| time to 60 in various places in the talos source. Doing a search for "sleep", you will find a few places. We need to identify which places are requirement and what the smallest value is. See [bug https://bugzilla.mozilla.org/show_bug.cgi?id=432764]
It takes a LONG time.
It might be that we are running out of entropy, especially for the startup tests. This isn't safe for users. On the device, you should do this as root:
mv /dev/random /dev/chaos ln -s /dev/urandom /dev/random
Also, we can disable the OS from regulating the CPU:
echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
