szlin#topic Software update09:14
sangorrinI am designing the architecture, but recently this was released09:15
sangorrinI want to investigate mbed Linux OS architecture well, maybe we can join efforts there09:15
sangorrinI find it interesting that they use runC for running applications in isolation09:16
sangorrinand I also like the fact that you can discover and manage the devices..09:16
sangorrinnothing else from my side09:17
sangorrinTODO: create report from survey09:17
sangorrinTODO: create architecture draft09:17
szlinsangorrin: mbed is designed for Arm devices, but I assumed the mechanism should be fine with x8609:18
sangorrinyes, I suppose it is not dependent on the architecture09:19
szlinsangorrin: thanks.09:19

*** vidda has quit IRC09:34
wagiszlin: somewhat. also in the conf call :(09:41
wagiszlin: I discussed the plans with Jan K. about -rt for 4.19-cip. I'll start working on this, so that we will have a -rt version for the upcoming 4.19-cip kernel soonnish09:42
szlinwagi: you got me09:43
szlinwagi: that's the question I want to ask :D09:43
wagiI somehow expected it. I don't expect a real problem but let's see09:43
wagi4.19-rt is still in the stabiization phase09:44
wagiso there might be some shake outs09:44
wagibut this is some which can be address upstream directly09:44
szlinwagi: thanks, do you have release schedule?09:45
wagi(English is hard, especially after the x-mas party)09:45
patersoncStill easier than German ;)09:45
wagiszlin: I start working tomorrow and I expect to have something beginning of January09:45
wagipatersonc: bah :)09:46
szlinwagi: awesome!09:46
wagiIt is mostly testing and make sure I dind't screw up the merging of the -rt patches09:48
wagibtw, I started to setup also my local lava instance09:48
wagiand I got access to patersonc setup, so I can make use of a bunch of test boards09:49
wagiI plan to work on some test cases too, so that we can integrage them into lava tests09:50
wagiThat should make poeple happy, I supoose09:51
wagiThe Linutronix test farm is working again:
wagiI worked with Linutronix's engineers together to get back to working09:53
szlinwagi: do you plan to add some test tools/ cases for -rt?09:53
wagibtw, the link is for the 4.4-rt not cip09:53
wagiszlin: my main goal is to get a baseline of reasonable testing expressed in scripts09:54
wagicurrently many tests are done by hand or encoded into some shell scripts which are living one many github accounts09:55
wagiMy pplan is to consilidate the tests and have them in lava and get them used by other -rtmaintainers09:56
wagiI've already done a similiar thing with the scripting around maintaining a release09:56
wagiWe have now a python script for maintaining -rt releases (supports also cip-rt)09:57
wagiwhich is used by all -rt maintaienrs09:57
wagimeanwhile I also working on a reimplemtation of cyclictest09:58
wagicalled jitterdebugger09:58
wagicyclictest is kind of hard to fix :)09:59
szlinwagi: ah, Despicable Me.09:59
wagiszlin: :D09:59
szlinwagi: How about rt-tests test suite?
wagiThe -rt stable maintainers have agreed to improve the tests in rt-tests10:01
wagijitterdebugger is supposed to replace cyclictest10:01
wagior at least this is my plan10:01
wagiThe main problem with cyclictest, it is hard to use10:02
wagijitterdebugger should give you correct results withouth a lot of command line options10:02
wagifurthermore, we (Wolfgang Mauerer) is planing to do some time series analysis10:03
wagiSo not just historgrams10:03
wagiThat is a great step forward regarding getting a better confidence on the -rt performance10:04
wagiWell, I need to defer to Wolfgang here. He is the real stastic pro10:04
szlinwagi: do you have release schedule for version 1.0?10:07
wagijust a sec10:07
wagiback, phone call irq10:21
wagiszlin: so far no schedule. I am workong on this topic only in my idle time10:21
wagiworking (!!)10:22
wagithe good thing is that I have a couple of contributors for jitterdebugger10:22
