10:27 AM jepler: seb_kuzminsky: just noticed this about devscripts compat level 7:
10:28 AM jepler: - dh_clean will read debian/clean and delete files listed there.
10:28 AM jepler: re mesaflash and -dfsg tarball probs

10:29 AM jepler: <jepler> seb_kuzminsky: wheezy-rtpeempt-i386 is still offline
02:57 PM skunkworks: what was the command to figure out what cache is connected/shared with what cores?
02:59 PM skunkworks: lscpu maybe
03:03 PM skunkworks: hmmm that doesn't have the cool text layout - atleast as far as I can tel
03:17 PM skunkworks: wow - on this j1900 - isolcpus=2,3 and idle=poll - I am getting 5us latency
03:17 PM skunkworks: with the livecd
03:23 PM skunkworks: still 5us
03:24 PM skunkworks: that is amazing. Maybe uspace could be used for stepping machines with some tweeking (isolating cores and such)
03:25 PM skunkworks: There was presentation where the rt-preempt group showed that their latency was just as good as rtai...
03:37 PM skunkworks: http://electronicsam.com/images/KandT/testing/user-04Jul2017-1172.png
03:47 PM skunkworks: still 5us ;)
04:06 PM jepler: skunkworks: wow
04:09 PM skunkworks: it has gone up... 5.3us ;)
04:56 PM andypugh: If I wanted all the good stuff from master merged into the andypugh/multispindle branch, what would be the best way to do it?
04:56 PM andypugh: Someone is hassling me because he wants multispindle.
04:57 PM andypugh: Or should I just tell him to bugger off, and pretend that the feature branch doesn’t exist?
05:02 PM jepler: origin/andypugh/JA14_multispindle ? If it's based off a numbered JA branch, then it's going to be tricky, because JA was rebased before it was merged. That means git doesn't really understand how the commits on master branch and your branch are related.
05:04 PM jepler: it looks like there's just a single commit, but it doesn't look like it readily adapts to the tip of the master branch
05:04 PM jepler: $ git cherry-pick origin/joints_axes14..origin/andypugh/JA14_multispindle
05:04 PM jepler: this is the command I tried, but it leaves many files with conflicts to be resolved
05:07 PM skunkworks: andypugh, rt_preeempt.. http://electronicsam.com/images/KandT/testing/user-04Jul2017-1172.png
05:15 PM andypugh: jepler: This is the problem that my interlocutor found.
05:16 PM andypugh: But I don’t really fancy comitting to the work needed to hand-merge the work at this time.
05:17 PM andypugh: On the subject of multispindle, what do you think of using the “$” symbol to specify a spindle. It’s unused at the moment, so very littlle chance of any conflicts…
05:35 PM JT-Shop: Tom_itx: did you try Stretch?
05:39 PM Tom_itx: i did a latency on the D525 and it did rather poorly
05:39 PM Tom_itx: the asrock pc did much better
05:39 PM Tom_itx: haven't tried anything else
05:39 PM JT-Shop: did you do master or 2.7?
05:40 PM Tom_itx: 2.7
05:40 PM Tom_itx: the iso
05:40 PM Tom_itx: the D525's aren't gonna do well with it i think
05:40 PM JT-Shop: I tried seb_kuzminsky suggestion to replace wheezy with stretch for master and it failed
05:40 PM Tom_itx: i'll go back to wheezy on the mill
05:40 PM JT-Shop: the 525 would do better with ubuntu 8 or 10
05:40 PM Tom_itx: i'm still recovering data from the failed hdd though
05:41 PM JT-Shop: hows that going?
05:41 PM Tom_itx: been running for ~4 days
05:41 PM Tom_itx: i just shut it off and will look at the img later
05:41 PM Tom_itx: i think i have configs somewhere but wanna make sure i have the latest ones
05:42 PM JT-Shop: I hear ya
05:42 PM Tom_itx: i think i have a good copy on the server
05:43 PM Tom_itx: what were you testing on?
05:44 PM JT-Shop: I never did get linuxcnc to load, apt-get update can't find it lol
05:44 PM Tom_itx: you're trying to build it then
05:44 PM Tom_itx: i just used the iso
05:49 PM JT-Shop: yea I want the Mate desktop and master
05:50 PM Tom_itx: i managed to get mate on wheezy
05:50 PM Tom_itx: didn't try on stretch
05:51 PM JT-Shop: you added it after the fact?
05:51 PM Tom_itx: yeah
05:51 PM JT-Shop: I may go that route after a while of failing
05:52 PM Tom_itx: jepler said it's a 1 line change to put it in the iso but then everybody would have their favorite request
05:53 PM JT-Shop: nice
05:53 PM Tom_itx: i bet somebody could twist his arm...
05:58 PM JT-Shop: give it a try
11:16 PM Tom_itx is now known as Tom_L
