OK, I have a new test version 3c59x.c (and an updated vortex-diag.c) that should handle this overload dynamically. I'll announce them on both driver-announce and vortex-announce in a few minutes. Please try the new driver: ________________ 3c59x.c:v0.99Xg 11/27/2002 ... Dynamically increase the RxPriorityThresh on every a Rx FIFO overrun. The default value is 4*32 bytes We increase it by 32 bytes up to 31*32 bytes. If Rx FIFO overruns continue we want on each corrupted packet! ________________ On Tue, 19 Nov 2002, Claude Pignol wrote: > Donald Becker wrote: > >Allow changing the Rx FIFO priority level with the -G <threshold-bytes> flag. > >Try setting > > -G 512 > > I try the new vortex-diag: > Registers berfore -G512 ... > Change the RX priority to 512 bytes .. > Error ratio: ( 127616 -123204)/(534880121-468076386)=.000066 > For the same period an interface with the default value has a ratio .00018 > > It seems that it goes in the right direction (there is no interface with > a ratio < .00012 with the default value). -- Donald Becker [email protected] Scyld Computing Corporation http://www.scyld.com 410 Severn Ave. Suite 210 Scyld Beowulf cluster system Annapolis MD 21403 410-990-9993 _______________________________________________ vortex mailing list [email protected] http://www.scyld.com/mailman/listinfo/vortex
