[linux-dvb] Latency ?

[Lauri Tischler <lauri.tischler@efore.fi>]

I tweaked the saa7146_core.c to set latency to 128,
mainly to see if I could get my NOVA-T (the DVB 3) to work
properly, without artefacts, (I have this crappy VIA based
uATX Motherboard)
Picture breaks and glitches whenewer there is a write to disk
and NOVA-T is in use.

Board 1 is NEXUS-T, Board 2 is NEXUS-S and Board 3 is NOVA-T

Could somebody explain to me what does the 'Max.Lat =38' mean,
does that mean that even if I set the latency to 128,
it will not take, the list below is from 'cat /proc/pci'

  Bus  0, device   8, function  0:
    Multimedia controller: Philips Semiconductors SAA7146 (rev 1).
      IRQ 5.
      Master Capable.  Latency=128.  Min Gnt=15.Max Lat=38.
