Re: [Emc-developers] EMC2 on Ubuntu 8.04 Hardy Heron - call for tests

[Mario. <em...@gm...>]

I started downloading now, but I already have a question.

On the Live CD, and then after installing, is there a realtine
performance test script ready?

In the old (2.1 EMD2 distro) I used a file with a script like this one:

/QUOTE BELOW

#!/bin/sh

sudo mkdir /dev/rtf; sudo mknod /dev/rtf/3 c 150 3; sudo mknod
/dev/rtf3 c 150 3;
cd /usr/realtime*/testsuite/kern/latency; ./run

/QUOTE HAS ENDED


If it is not there, may you please schedule adding it right on the
desktop? It will make testing the usefulness of different platforms
much easier and faster. As for the above script, I fould in on a
Windows drive, not sure if it is the same I use on linux...

Thanks.
