[01:48:35] <jepler> hm not a lot of skylake-generation motherboards have the good old 33MHz PCI sot
[01:49:01] <Tom_itx> what's a good modern mb to get?
[01:49:55] <jepler> no idea, I haven't bought desktop PC hardware in a few years myself
[01:50:01] <Tom_itx> me either
[01:51:58] <jepler> it's amazing how BAD hardware can be that makes it to market. One particular MB I looked at got 40% 1-star ratings on newegg and 70% 1-star ratings on amazon. "stopped booting after a week" "powers off after 30 seconds without displaying anything" etc
[01:52:19] <jepler> and you can get a 3-star review for "under windows, continuously plays the headphone insertion sound but is OK other than that"
[01:52:25] <jepler> plays the sound continuously, that is
[01:52:36] <Tom_itx> last ones i got were those as rock 1900 boards
[01:53:01] <Tom_itx> kinda slow for a cad pc
[01:53:18] <Tom_itx> the ssd i just got did help
[01:54:13] <Tom_itx> those have sure come down in price
[01:55:15] <jepler> yeah, that is nice
[01:55:34] <jepler> not quite cheap enough to store 15 years of digital photos yet
[01:56:26] <Tom_itx> i didn't think 500G for ~150 was bad

[02:01:12] <jepler> the system I'm shopping for is for gaming first, building software like linuxcnc second. but if I don't get a traditional PCI slot, I can't test on the mesa 5i20 anymore, which is the only example I have of a card that needs a firmware loaded when linuxcnc starts.
[02:01:59] <Tom_itx> i'm not even sure what's out there nowdays.. too far outta the loop
[02:02:28] <jepler> my initial thought was that I could do worse than selecting Intel's current gen CPU, which is Skylake
[02:03:00] <jepler> and that for building software, the 4 core / 8 thread i7-series would be worth the price jump (vs the 4 core / 4 thread i5-series)
[02:04:03] <jepler> but then I started motherboard shopping. and there are just so many bad reviews of the skylake-compatible motherboards which seem to just barely work...
[02:08:22] <Tom_itx> is AMD worth looking at anymore?
[02:08:27] <jepler> e.g., this one:
http://www.amazon.com/-/dp/B012AQGKXC/ (oh it's only 67% 1-star reviews, not 70% as I had claimed)
[02:09:50] <Tom_itx> http://www.tomshardware.com/reviews/best-intel-amd-motherboard,3902.html
[02:09:54] <Tom_itx> i was looking at that a bit
[02:10:00] <jepler> I haven't been looking at AMD this time around. My general impression is that their CPUs are fine for "value" segment but not "performance" segment. and while I hear people like pcw and skunksleep having good luck with intel chips for realtime, I don't hear much about AMDs. but that doesn't mean they aren't OK..
[02:10:28] <jepler> Yeah, that amazon link is to the second one on tom's list
[02:12:09] <Tom_itx> these last couple boards i got were fanless which is nice but i suppose when you get into the perfomance boards it's a requirement
[02:13:14] <jepler> there will be fans
[02:19:51] <skunkworks> it has been a while since I have tested amd motherboards
[02:20:08] <skunkworks> though that is what is running the k&t..

[14:17:16] <CaptHindsight> jepler: all of memleaks RTAI work over the past few years was done on AMD
[14:18:23] <CaptHindsight> it was the only x86 silicon that allowed you to have your own firmware until last year
[14:20:15] <CaptHindsight> Intel has had a few binaries in the BIOS that are used for backdoor, phone home, remote control etc that operates completely out of band...
[14:21:00] <CaptHindsight> I wonder how it might effect real time when it's accessed

[15:28:59] <jepler> apparently debian stable (kernel & graphics) doesn't work too well with skylake, maybe I should go Broadwell instead...
[15:33:05] <pcw_home> Also supposedly you want a 4.4 or later kernel

[15:33:56] <jepler> 10:33:47 up 6 days, 22:11, 34 users, load average: 0.48, 0.58, 0.58
[15:34:13] <jepler> it's OK on my laptop though I don't actually run linuxcnc much
[15:34:20] <jepler> but for desktop stuff it's stable
[15:34:28] <pcw_home> I either had terrible latency or crashes
[15:35:39] <pcw_home> (with 4.4.4-rt9+)
[15:40:09] <pcw_home> this is on my clunky old core-duo
[15:40:10] <pcw_home> currently running 4.1.15-rt18-rc1 which runs hm2-eth at 4 KHz reliably with
[15:40:11] <Tom_itx> which is broadwell?

[15:41:24] <pcw_home> its a technology stepping not a specific CPU
[15:41:51] <Tom_itx> oh
[15:42:15] <pcw_home> its the 5th gen Intel Core series (Skylake is 6 Ivy bridge is 4)
[15:43:00] <Tom_itx> is skylake quite a bit better than i5?
[15:43:27] <Tom_itx> i don't quite understand cpu internals but it has more pipes
[15:43:32] <pcw_home> well there are skylake pentiums, i3s,I5s and I7s
[15:43:35] <Tom_itx> sounds bigger :)
[15:44:01] <Tom_itx> too confusin
[15:44:02] <Tom_itx> g
[15:44:18] <pcw_home> I think its mainly a bit better power consumption and faster memory (DDR4)
[15:45:58] <pcw_home> the current fastest desktop skylake I7 chip is not noticeably faster that the Ivy bridge version
[15:45:59] <pcw_home> but in general they are cooler
[15:46:34] <Tom_itx> is there just one fpga size selection on the 5i25?
[15:46:43] <pcw_home> yes

[15:49:22] <pcw_home> I should put that trick for safely testing a 5i25/7I92 bitfile in the manual
[15:53:01] * jepler hmms
[15:53:51] <jepler> this is write to the so-called "fallback" area, so that a subsequent reinitialization gets you the default area with good configuration?
[15:54:19] <jepler> I wonder if the hostmot2 driver should have a mode where it reboots into the second area at startup, and into the first area at exit
[15:54:49] <jepler> then the normal usage would be to leave the first config untouched
[15:55:04] <pcw_home> yes write to fallback and then reload from fallback
[15:56:23] <pcw_home> all current cheap cards (1 EEPROM, XC9SLX9) actually have room for 4 configs

[17:44:02] <emcPT> Hello to all. Sometime ago I made some changes on linuxcnc code that I want to share. What is the best way to share my code?
[17:44:43] <emcPT> Code is simple and tested (over one year) and it is related with tool tip direction.
[17:46:20] <jepler> (I am only here for a moment)
[17:47:03] <jepler> emcPT: if you use github, you can create a fork of linuxcnc, then submit your changes as a pull request. a fork is also a way for interested users to access your modified version even before it is added to "official" linuxcnc.
[17:47:16] <jepler> http://linuxcnc.org/docs/2.7/html/code/contributing-to-linuxcnc.html#_linuxcnc_on_github (the whole document is good to read)
[17:47:19] <jepler> bye
[18:00:18] <emcPT> Well I must say that I try before to use git (about one year ago when the changes were done), but I was not able to. What I did: pulled and changed the source code under a directory named linuxcnc-dev. I also have sure that it builds.
[18:00:56] <emcPT> Should I now use git add filename1 filename2 ... ?
[18:05:21] -!- tinkerer [tinkerer!~tinkerer@mail.play-pla.net] has joined #linuxcnc-devel
[18:05:33] <mozmck> emcPT: yes, git add will add the files, then you have to commit them.
[18:08:56] -!- joem_ has quit [Quit: Leaving]
[18:10:56] <emcPT> Ok, I will try. For now one question: I have made changes both on ioControl_v2.cc and ioControl.cc
[18:11:02] <emcPT> Both files are identical.
[18:11:31] <emcPT> Are both files used, or only the v2 version, that I suppose is newer ?

[21:16:24] <mozmck> emcPT: Although jepler mentioned using github, it may be easier to send a patch to the mailing list. I think "git format-patch HEAD~" (without the quotes) will make a file with a patch of your last commit.
[21:25:30] <emcPT> Ok regarding the mailing list. Thank you for that info. If git hub was to be used, now that I made the commit, I must do anything else? This is something that is already online for revision or it is only on my PC?
