devf-generic question

Hi all,

I’m pretty much lame with QNX - sorry…

I’m using a 206MHz PPC405 based board with qnx 6.2 and the flash is accessed trough the generic fs
(devf-generic). So my question is:

Is it a compressed filesystem?
Is it a journaling fs?
If yes - how heavy is the CPU load for compression/joyrnaling?
Can this be a performance problem on the 206MHz power pc?
Where can I find some more detailed info on the qnx and flash filesystems coming with the neutrino
kernel?

Best Regards,
