07:31 AM pcw_home: Yay! Preempt-RT v4.9.18-rt14 fixes the bad latency on >4.1 kernels on Core Duos (and maybe other older CPUs)
07:33 AM pcw_home: so _maybe_ a single Preempt-RT kernel will work with wide variety of machines now
07:33 AM jthornton: which os are you running that on?
07:34 AM pcw_home: This is on Ubuntu 16.04
07:34 AM pcw_home: but it should apply to all
07:35 AM jthornton: 64 bit?
07:35 AM pcw_home: this is 32, I will try on 64 bit mint on Monday
07:37 AM jthornton: hmm the default download is 64bit
07:38 AM pcw_home: before I could never get any of the newer kernels (> 4.1) to have decent latency on older machines
07:38 AM pcw_home: 4.4, 4.6, 4.8, 4.9 before this version all had terrible latency on my older test systems
07:38 AM pcw_home: (32 or 64 bit)
07:39 AM pcw_home: terrible meaning >1 ms after a few minutes
07:40 AM jthornton: when I tried ubuntu 12 I think the interface was horrible iirc
07:40 AM jthornton: everything was hidden
07:40 AM pcw_home: so the Preempt-RT people definitely fixed something
07:41 AM pcw_home: I dont mind ubuntu/unity if you turn on the title bar menus
07:41 AM pcw_home: I think Mints a little nicer though
07:42 AM jthornton: yea I like mint
07:44 AM pcw_home: I think the only reason to use 32 bit for LinuxCNC now is if you have RTAI/uspace combined
07:44 AM pcw_home: (as I have on my Wheezy test machine)
07:44 AM jthornton: I need to try and get mint 18 up and going with master uspace
07:44 AM jthornton: so 64bit for uspace is ok?
07:45 AM pcw_home: Yea its fine
07:45 AM jthornton: I'll try and build that this weekend
07:46 AM pcw_home: I have 2 test system running mint 18 64 bit uspace master 24/7
07:46 AM pcw_home: Jepler just fixed a uspace bug with master/Mint18/Ubuntu16
07:47 AM pcw_home: well a week or two ago
07:48 AM pcw_home: image2gcode is still broken on mint18/ubuntu16
07:48 AM pcw_home: there may be other subtle things busted as I mainly am testing hardware, not exotic GUIs etc
08:35 AM jthornton: I got mint 18 64bit installed but free time is over so I'll try and get rt preempt in the morning
11:36 AM JT-Shop: how do you merge this fix?
11:40 AM cradek: when you go to that url, you can see that he's put the changes on top of the master branch
11:40 AM cradek: is that where you want to merge them?
11:42 AM JT-Shop: no, they should go in 2.7
11:42 AM cradek: ok then you can't just follow the instructions it gives
11:43 AM JT-Shop: I see that it is in master now
11:43 AM cradek: also I see they're not signed off, so you would need to get him to sign off each one, or do it yourself for him
11:44 AM cradek: the same goes for moving the commits to 2.7 branch: either you have to ask him, or do it yourself
11:44 AM JT-Shop: it says I'm not authorized to merge this pull request...
11:44 AM cradek: you never do it by pushing that button
11:45 AM cradek: if the pull request is signed off and on the right branch, you CAN do it by following the "command line instructions"
11:45 AM cradek: but in this case neither will work :-/
11:46 AM JT-Shop: hmm I'm not seeing the command line instructions, is it on that page?
11:46 AM cradek: moving them to 2.7 and doing the signoff for him (which I think you could just do for typo fixes) are things you'd use git rebase for
11:46 AM cradek: yes right next to the button there's a link that makes them appear
11:48 AM JT-Shop: maybe it doesn't show up if your not authorized
11:49 AM cradek: hm are you logged in?
11:49 AM JT-Shop: yes
12:05 PM cradek: JT-Shop: I can rebase (to 2.7) and sign-off his two changes. Do you want me to just push it, or do you want to work with him to do those things so he has those skills in the future?
01:04 PM JT-Shop: looks like he made another one for 2.7, but I can't tell if he signed them off or not
02:22 PM JT-Shop: cradek: is everything in order now?
02:42 PM KGB-linuxcnc: 03Alexander Brock 052.7 3294172 06linuxcnc 10configs/apps/parport/README 10docs/src/hal/basic-hal.txt 10src/hal/components/thcud.comp Fix typos * 14http://git.linuxcnc.org/?p=linuxcnc.git;a=commitdiff;h=3294172
02:42 PM cradek: looks good
02:43 PM cradek: I added a blank line between the commit message and the Signed-off-by just to be sure it's recognized, but that's the only change I made
03:10 PM JT-Shop: cool, thanks for helping
05:26 PM Roguish_ is now known as Roguish
10:27 PM KGB-linuxcnc: 03Dewey Garrett 052.7 4c9c4b3 06linuxcnc 10nc_files/ngcgui_lib/rectangle_probe.ngc rectangle_probe.ngc fix typo for reported #<probez> * 14http://git.linuxcnc.org/?p=linuxcnc.git;a=commitdiff;h=4c9c4b3
