[linux-audio-dev] Re: pci gfx card / jack xruns / pci latencies
Hello Florian, Is this with kernel 2.6.x or 2.4.x? I remember there were some problems with Matrox cards, that were initially not included in the 2.4.x low-latency patch, but I thought that at some point Andrew included them. http://www.eca.cx/lad/2002/06/0076.html maarten

It seems though that this is independent of the kernel version. I booted into 2.4.22 with LL+preempt and it shows the exact same behaviour as did 2.6.7 vanilla, 2.6.7-bk10-ck5-H3 and 2.6.8-rc1-mm1... I think the card is just not good.. I'm also wondering about the weird lspci -v output which reports no latency for the matrox card [and it's not bus master like all other pci devices i have]..

Btw: i use Xfree's mga driver. i never played with DRI, should i? FLo -- Palimm Palimm! Sounds/Ware: http://affenbande.org/~tapas/

From man mga: Option PciRetry boolean Enable or disable PCI retries. Default: off. -- Paul Winkler http://www.slinkp.com

From man mga: Option PciRetry boolean Enable or disable PCI retries. Default: off. Thanks for the hint. I didn't even know man pages for the X11 drivers existed.. Cool. Didn't help though ;) Well, anyways, i'll try some other pci cards today [as i managed to talk a budy of mine into letting me have some for tests].. I'll let you guys know my findings.
