[16:57:20] <seb_kuzminsky> ah, that makes sense then, seems like a good feature rather than a bug
[16:57:42] <seb_kuzminsky> do you know about debian/configure and dpkg-checkbuilddeps? those help you install everything needed for a full build
[16:59:33] <dgarr> like anyone cares about xemc for joints_axes ?
[17:01:33] <jepler> do we have a better low-graphics GUI than xemc?
[17:01:40] <jepler> I guess tkemc is just about as low-resource
[17:01:47] <jepler> I don't care to maintain xemc personally
[17:02:43] <jepler> before scheduling xemc for removal better drop an e-mail to the developer list though
[17:07:07] <jepler> on further thought, no harm in disabling it in ja if it's broken, so as not to stop package building while waiting for a purely hypothetical developer who would like to fix it

[18:05:47] <seb_kuzminsky> dgarr: hmm, my armhf buildslave disconnected from the buildmaster, and has not reconnected
[18:05:55] <seb_kuzminsky> rerunning the build will not do anything until the buildslave reconnects
[18:06:20] <seb_kuzminsky> (and i think the buildmaster will automatically rerun the interrupted build when the slave reconnects)
[18:07:32] <seb_kuzminsky> the armhf buildslave does not respond to ping, and i'm at work so i can't get to it to inspect it any closer
[18:07:41] <seb_kuzminsky> i'll look at it tonight, sorry for the outage

[19:55:14] <andypugh> I have just been told that I am wrong to say that LinuxCNC doesn’t work with Xenomai. Have I been labouring under a misapprehension?
[19:55:22] <andypugh> https://forum.linuxcnc.org/forum/9-installing-linuxcnc/29867-ubuntu-14-04-1-linuxcnc-help?start=20#65400
[20:03:52] <jepler> those links include a whole linuxcnc.tar.gz

[20:04:06] -!- the_wench has quit [Ping timeout: 240 seconds]
[20:04:07] <jepler> pretty sure the 2.7 and master branches from linuxcnc.org doesn't support xenomai
[20:04:36] <jepler> if tjmarch wants to contribute xenomai patches to linuxcnc.org I'll cast my eyes over them. but it has to be a patch not a whole .tar.gz file!
[20:04:36] <micges> some docs and scripts in there
[20:04:59] -!- archivist has quit [Ping timeout: 264 seconds]
[20:09:32] <andypugh> The readme says to use —with-uspace (or whatever it actually is) to build for Xenomai.
[20:10:37] <andypugh> I was too lazy to go into any more detail, I have other projects.
[20:10:49] <jepler> don't I know how that is!

[20:55:21] <andypugh> Is is possible that LinuxCNC on a Xenomai kernel would use POSIX threads? (And does that mean that Xenomai is used, or ignored?)
[21:00:02] <jepler> in 2.7 and master branch uspace, a number of things are checked to find out if the kernel is realtime capable
[21:00:11] <jepler> one is looking in the uname for "PREEMPT RT" as a substring
[21:00:26] <jepler> this test will not pass on xenomai afaik
[21:00:37] <jepler> that's why I assume that guy is posting a linuxcnc.tar.gz
[21:00:44] <jepler> he has some random patches that may or may not be good ones
[21:01:16] <jepler> .. look at static int detect_realtime in src/rtapi/uspace_common.h
[21:01:29] -!- justanotheruser has quit [Read error: Connection reset by peer]
[21:17:38] <andypugh> The .tar.gz isn’t LinuxCNC, it’s a set of user guides (Ubuntun, Mint) and inkscape extensions.
[21:22:35] <jepler> oh well I dunno then
[21:23:03] <andypugh> posix threads default?
[21:23:15] <andypugh> How do you tell?
[21:23:35] <jepler> static int harden_rt()
[21:23:35] <jepler> {
[21:23:35] <jepler> if(!rtapi_is_realtime()) return -EINVAL;
[21:23:52] <jepler> if rtapi_is_realtime() returns false, then it doesn't do the "harden realtime" steps
[21:24:04] <jepler> if(harden_rt() < 0)
[21:24:04] <jepler> {
[21:24:04] <jepler> rtapi_print_msg(RTAPI_MSG_ERR, "Note: Using POSIX non-realtime\n");
[21:24:07] <jepler> return new Posix(SCHED_OTHER);
[21:24:09] <jepler> } else {
[21:24:12] <jepler> rtapi_print_msg(RTAPI_MSG_ERR, "Note: Using POSIX realtime\n");
[21:24:14] <jepler> return new Posix(SCHED_FIFO);
[21:24:17] <jepler> }
[21:24:20] <jepler> and it doesn't create SCHED_FIFO realtime threads
[21:24:37] -!- Balestrino has quit []
[21:25:40] <jepler> so if this poster is really saying that unmodified linuxcnc uspace runs with realtime under xenomai, I guess you'd have to say I am surprised and would like to know why.
[21:26:08] <jepler> s/if.*unmodified/if unmodified/
[21:28:26] <jepler> and if that's not the case it would be good to correct misinformation
[21:44:29] <seb_kuzminsky> i'm sure linuxcnc will run under xenomai, but like jepler i think it will not have realtime performance that's much/any better than with a vanilla kernel
[21:44:39] -!- Tecan has quit [Changing host]
[21:45:37] <jepler> right
[21:45:45] <jepler> I don't think linuxcnc *uses* xenomai realtime effectively
