[08:40:55] <skunkworks__> 2 days at 2khz
[12:44:07] <Connor> skunkworks__: 2 days at 2khz ??
[12:45:01] <skunkworks__> testing a 7i80 (Ethernet connected mesa card) running the servo loop at 2khz
[12:45:18] <Connor> Ah
[12:46:03] <skunkworks__> realtime control loop over Ethernet is just cool!
[12:50:17] <Connor> Sounds like it.
[12:50:35] <Connor> Just now converting my machine from pport to MESA 5i25 / 7i76
[12:58:01] <skunkworks__> nice
[16:59:12] <PCW> well g3258 looks pretty decent RTAI wise ~6 usec base and ~4 usec servo running youtube flash and a bunch of glxgears
[16:59:35] <PCW> no bios changes from default yet
[18:02:19] <CaptHindsight> one thing that memleak spent some time on with the newer RTAI branch is getting <25uS latency for RTAI along with smooth video rendering and playback
[18:04:40] <CaptHindsight> it looks like some video drivers access hardware directly and violate anything RTAI does to schedule threads
[18:05:53] <CaptHindsight> I think he traced something back to X that didn't care what RTAI was doing
[18:10:09] <PCW> The G3258 gets about 21 usec latency on preemt-RT
[18:11:47] <PCW> and seems to run hm2_eth easily at 2.5 KHz
[18:12:56] <CaptHindsight> PCW: any launch date for the ethernet fpga boards?
[18:14:16] <PCW> they are all available now (well except 7I92) we have not been saying much until we are really sure they work well for linuxcnc
[18:14:41] <CaptHindsight> yeah I meant the 7i92
[18:15:16] <PCW> middle of this month I hope
[19:25:29] <CaptHindsight> camview works in Wheezy with Axis
[21:54:58] <skunkworks> CaptHindsight: was it painful?
[22:01:27] <CaptHindsight> still is
[22:02:09] <CaptHindsight> getting mplayer in a tab is pretty simple
