faketty_hijackled standalone kernel patch available

[James v. Z. <ja...@dv...>]

Hi all.

I have created a standalone faketty0.05_hijackled patch downloadable
from my homepage; initially against 2.6.16.9, but it should apply
broadly.

I have been getting excellent results with realtime multimedia on a 3Ghz
P4 - I am hoping to get realtime multi-console happenning, but there are
some catches. While it works fine for most applications, indeed, it's
overall latencies are down considerably, PCI video kills the mix; a
multi-console machine will be good for realtime audio only if one uses
the AGP console only, logging out all other consoles and leaving them
alone.

Any PCI console activity causes audible audio glitches. Bear in mind
that we are recording 32bit audio files from 24bit sources at 96Khz, so
there is a significantly higher load than using 16bit audio. over 4x.

I am investigating ways to drastic lower the realtime performance impact
from PCI video cards.
Is anyone aware of methods, kernel tweaks or tools that may assist in
altering the PCI performance of the PCI video?

We effectively don't care about video performance on pci consoles. If it
means they're noticably slower but audio operates in realtime, that's
great.

Does anyone have any info on how a USB console might load the system?

I will be posting realtime kernels with faketty included soon,  followed
by a more 'vanilla' kernel sometime over the next week or tso.

Apart from the audio glitches that you may not see or care about outside
of pro-audio usage, the realtime kernels provide excellent desktop
interactivity.
