04:10 AM Tom_L: morning
04:45 AM JT-Cave: morning
05:20 AM Deejay: moin
06:51 AM lcnc-relay: <Travis Farmer> Morning
07:22 AM Tom_L: rain
07:46 AM lcnc-relay: <Travis Farmer> sun, much much sun... 96F+ predicted
07:58 AM lcnc-relay: <vibram> same here in france, though day
08:58 AM JT-Cave: 15 miles this morning
10:20 AM lcnc-relay: <roguish> JT-Cave: outstanding..... how are the gears ???
10:28 AM JT-Shop: 34-26 is too far, I have another one coming with a 34-28
10:31 AM JT-Shop: it's really a jump when down shifting as a hill gets steeper
12:11 PM Gardenweazel: Question regarding QTDragon_hd. Once the UI is loaded there is a DRO section. What does the REFX, REFY and REFZ button do?
12:30 PM lcnc-relay: <skunkworks8841> I would guess homing?
12:35 PM lcnc-relay: <roguish> Gardenweazel: I believe it zeroes the particular G5x you are in.
12:36 PM lcnc-relay: <roguish> there is a drop down that you can use to select the G5x, or you can set it via MDI command
12:36 PM lcnc-relay: <roguish> try it and see....
12:47 PM Tom_L: mesaflash epp thing solved
12:51 PM Tom_L: pcw--home, changing the board name fixed the mesaflash issue
12:51 PM Tom_L: no need to test
12:53 PM Tom_L: i thought with newer mesaflash versions there was a way to list the board names...
12:57 PM JT-Shop: list the board that is found?
12:57 PM Tom_L: if you misspell one i thought there was a way to get a board list
12:58 PM Tom_L: box in a box arrived
12:58 PM Tom_L: so from 3.4.3 forward all the new board names are effective
12:59 PM JT-Shop: https://github.com/jethornton/mesact/blob/master/mesact/src/libmesact/flash.py#L68
12:59 PM Tom_L: i knew 7i80 changed to 7i80HD-16 or -25
12:59 PM Tom_L: but didn't think about it on the 7i90
12:59 PM * JT-Shop heads out to find a fire extinguisher for the C8
12:59 PM Tom_L: it's not ethernet
01:00 PM JT-Shop: I think you can specify other types
01:00 PM JT-Shop: might try man mesaflash
01:00 PM Tom_L: i was looking at the --help
01:00 PM Tom_L: no man available
01:11 PM pcw--home: I'll take a look, There was an issue with the 7I80 that was patched in near top level code that seems to have affected the 7I90
01:12 PM pcw--home: I think using bare "7I90" should print the list of cards (and the list should show "7I90HD")
01:13 PM Tom_L: i was able to read the 7i90 using 7i90HD just fine on versions 3.4.3 and the very latest version
01:13 PM Tom_L: the name changed around 3.4.2 & 3.4.3
01:13 PM Tom_L: it just returns 'no 7i90 board found' or something to that effect
01:14 PM CaptHindsight: pcw--home: are parts getting easier to find? Did you ever get parts that you tried to order from back on '20 or '21?
01:14 PM CaptHindsight: i recall the 2 year lead times for some devices
01:15 PM pcw--home: Yes, much easier now
01:15 PM Tom_L: it would be handy if it did list them
01:16 PM Tom_L: i'm guessing the names changed to acomodate names for the new fpga chips
01:16 PM pcw--home: Well it does but it lists the wrong name
01:16 PM Tom_L: what's the command for that? i've tried several
01:17 PM pcw--home: Yes needed to change the name munging to not have collisions
01:18 PM pcw--home: there's no command but "mesaflash --device biff" will work
01:18 PM Tom_L: i knew i'd seen that but forgot how to do it
01:29 PM Tom_L: well at least my local copy prints it right now :)
01:35 PM lcnc-relay: <Travis Farmer> 101F in my workshop right now...
01:36 PM pcw--home: Well I Fixed it but now have somehow broken my git login... sigh
01:37 PM Tom_L: and i can't because i don't have rights :)
01:39 PM pcw--home: git push used to always ask for my password but I accidentally changed something and it no longer asks
01:39 PM Tom_L: if you have your git credentials on the local pc it won't ask
01:40 PM Tom_L: and the ssh keys
01:42 PM pcw--home: It has the keys but not the password but I clicked a checkbox on the popup tha used to ask for the password and it no longer asks (and always fails)
01:42 PM Tom_L: git config --global user.name git config --global user.email
01:42 PM Tom_L: that's what i do anyway
01:43 PM Tom_L: on any pc you want git access to
01:51 PM pcw--home: Still can't figure out what I changed...
02:07 PM lcnc-relay: <TurBoss> do "ssh git@github.com" work?
02:08 PM pcw--home: same error
02:09 PM pcw--home: I didn't do anything with my keys but it used to ask for my password and no longer does
02:10 PM lcnc-relay: <TurBoss> check this link 🙂 https://docs.github.com/en/authentication/connecting-to-github-with-ssh/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent#adding-your-ssh-key-to-the-ssh-agent
02:11 PM xxcoder: lol ouch burn https://x.com/Jbanklestankle1/status/1803038951906693301
02:12 PM xxcoder: (on boeing)
02:13 PM pcw--home: Yeah I had done all that a few years ago and was hoping not to have to repeat it
02:28 PM pcw-home: Tom_L: 7I90 issue should be fixed in 3.5.9
02:51 PM roycroft: so there were two "workbenches" in the shop
02:51 PM roycroft: both kind of wonky, to be generous
02:51 PM roycroft: i demo'ed one of them at lunch today
02:51 PM roycroft: the benchtop was nice - two slabs of old growth fir 4x12, bolted firmly together
02:52 PM roycroft: it was pretty beat up, but it's thick enough that i can resurface it, so i saved it intact, which turned out to be a lot of work, especially with my only having one arm still
02:52 PM roycroft: but pulleys/come-alongs/etc helped
02:53 PM roycroft: the "base", though, was just some 1x2s and 2x2s nailed together sloppily
02:53 PM roycroft: it's a wonder the benchtop never collapsed before i knocked it down today
02:53 PM roycroft: it was attached to the wall, kind of
02:54 PM roycroft: i get the concept of making do with what one has, but this was ridiculous
02:59 PM Tom_L: pcw-home, thanks
02:59 PM pcw-home: It should print the valid card list if you --device 7I90
03:00 PM Tom_L: i'll be building up a test pc later today
03:01 PM Tom_L: mostly to run flexgui live
03:01 PM pcw-home: I've got some other mesaflash changes but my knowledge of C variables and scope is lacking (and mesaflash is pretty layered)
03:02 PM Tom_L: what c i did know i forgot
03:02 PM Tom_L: most of that was imbedded
03:02 PM pcw-home: Yeah
03:04 PM pcw-home: Trying to get the inmux scan size reported in the pin description but the printout/xml is in the highest layer and the gathering data is in the lowest
03:06 PM Tom_L: any of the other boards in the --device list need a name fix?
03:07 PM Tom_L: none i can see
03:08 PM pcw-home: I think it just missed that the 7I90 would be affected by the name munging change
03:08 PM Tom_L: alot of those old cards probably won't be reproduced and if they are it will be quite a while
03:09 PM Tom_L: ie 50 pin header
03:09 PM pcw-home: (and not many people are updating 7I90 firmware at this point, though we are making a few more)
03:10 PM Tom_L: i've had one in the mill for ages and have a spare otherwise i'd be rewiring for a 7i96s
04:08 PM lcnc-relay: <skunkworks8841> Well.. we have 3/4 inch black pipe buried to the top of the hill.. comes up out of the ground around every 100ft or more.. I just used a vacuum and was able to pull twine the whole distance
04:08 PM lcnc-relay: <skunkworks8841> So - that is what I will run the fiber down
04:09 PM lcnc-relay: <skunkworks8841> Used a corner of a sandwich bag as a 'parachute'
04:10 PM Tom_L: not rusted out?
04:11 PM lcnc-relay: <skunkworks8841> I think there was a bit of dirt/nuts as I had to kinda pull back a foot and let it go again
04:11 PM lcnc-relay: <skunkworks8841> Black plastic
04:12 PM Tom_L: ahh i thought you mean like gas pipe opposed to galv
04:12 PM lcnc-relay: <skunkworks8841> No.. burriable water pipe
04:12 PM Tom_L: right
04:14 PM Tom_L: string should go right thru that
04:15 PM lcnc-relay: <skunkworks8841> Dad had used those garden plastic tool thing to cover the holes . They have fallen apart..
04:15 PM lcnc-relay: <skunkworks8841> Have to figure out what to do with it..
04:16 PM lcnc-relay: <skunkworks8841> (two 4 inch pipes and the two water pipes
04:16 PM Tom_L: to cap the ends?
04:17 PM lcnc-relay: <skunkworks8841> Yes
04:17 PM Tom_L: or to gain access to them
04:17 PM Tom_L: sprinkler box would be an option for that
04:18 PM lcnc-relay: <skunkworks8841> To be able to keep them covered and have access
04:18 PM Tom_L: ^^
04:19 PM Tom_L: https://www.homedepot.com/p/Orbit-12-in-Standard-Valve-Box-53212/202206749?source=shoppingads&locale=en-US
04:19 PM Tom_L: how deep are they burried?
04:20 PM Tom_L: i covered a couple valves with some gallon jugs with the top cut out
04:24 PM lcnc-relay: <skunkworks8841> That might work.. they just come out of the ground a foot or so
04:24 PM Tom_L: the jugs? maybe... tie them on so they don't get knocked off
04:25 PM Tom_L: i used them on the valves cause i was too lazy to get a bigger box when i added a couple stations
04:26 PM Tom_L: buried next to the box and marked
04:28 PM Tom_L: i have a whole collection of windsheld washer fluid jugs... you'd be surprised what you can do with em...
04:29 PM Tom_L: seems as soon as i get some, the boys take em
04:32 PM Gardenweazel: Yep, thanks! I was just thinking about renaming some of the buttons for noob's like me or adding a more descriptive hover. LOL
06:23 PM -!- #linuxcnc mode set to +v by ChanServ
06:55 PM rdtsc_away is now known as rdtsc
07:26 PM lcnc-relay: <skunkworks8841> Tom_l:
07:27 PM lcnc-relay: <skunkworks8841> https://jauriarts.org/_matrix/media/v3/download/jauriarts.org/DCbCjdyrnRXropBpwNjRtQAF/PXL_20240619_232448664.MP.jpg
07:28 PM lcnc-relay: <skunkworks8841> I put an outlet in there now - which I didn't know the 10-3 came up there.. This is about 20ft from where we are going to build a tree house.. s
07:28 PM lcnc-relay: <skunkworks8841> so that worked out great!
07:28 PM lcnc-relay: <skunkworks8841> I need to come up with a frame and box to keep the tubes out of the weather (and mount the outlet box on something
07:29 PM Tom_L: cool
07:29 PM xxcoder: nice
07:29 PM lcnc-relay: <skunkworks8841> (you can see the twine out of the one hose - just have to do that 2 more times)
07:30 PM Tom_L: yup
07:30 PM Tom_L: i'd partially bury one of those sprinkler boxes or use the 1gal jugs to cover them
07:31 PM lcnc-relay: <skunkworks8841> I will have to look at those... - that might be what I do..
07:31 PM Tom_L: the boxes aren't water tight though
07:31 PM Tom_L: you can get all shapes and sizes
07:31 PM lcnc-relay: <skunkworks8841> well - nether were the other garden boxes
07:31 PM Tom_L: keeping the tubes above grade is a good idea though
07:31 PM Tom_L: for runoff
07:31 PM lcnc-relay: <skunkworks8841> yes
07:32 PM Tom_L: swapping motherboards
07:32 PM lcnc-relay: <skunkworks8841> it is pretty steep - so any water that got in would only be at the bottom few feet.
07:32 PM lcnc-relay: <skunkworks8841> the 3/4 pipe had a little water it it at the bottom - the vacuum cleaner sucked it out
07:32 PM Tom_L: 2 identical ones one both with i5, one is 2.x ghz the other is 3.x ghz
07:32 PM lcnc-relay: <skunkworks8841> want more speed?
07:32 PM Tom_L: the 2.x ghz chip has far better latency
07:33 PM lcnc-relay: <skunkworks8841> ah
07:33 PM Tom_L: i don't mind what i have in my main pc
07:33 PM Tom_L: i have an i7 in a box i might try if this doesn't work out
07:34 PM Tom_L: had the new box all set up, ran a test, now swapping both out again
07:34 PM lcnc-relay: <skunkworks8841> I splurged a few months ago and bought a 7900x3d..
07:34 PM Tom_L: one is back up
07:34 PM lcnc-relay: <skunkworks8841> it games really nice.. but I don't game much.
07:35 PM Tom_L: now the latency looks better on the bad one... wtf
07:36 PM lcnc-relay: <skunkworks8841> lol
07:36 PM Tom_L: identical monitors & graphics
07:36 PM lcnc-relay: <skunkworks8841> what latency are you seeing?
07:36 PM Tom_L: i'll take a pic after it runs a bit
07:36 PM xxcoder: you sure its not doing something like disk indexing
07:37 PM lcnc-relay: <skunkworks8841> lol - on linux? does it do that?
07:37 PM xxcoder: yeah
07:37 PM lcnc-relay: <skunkworks8841> huh
07:37 PM xxcoder: its for searches etc
07:37 PM Tom_L: how often does it do that?
07:37 PM xxcoder: not all distros do have it but yeah
07:37 PM xxcoder: not sure
07:38 PM Tom_L: i've run it for quite some time on the bench so if it was gonna, it shoulda
07:38 PM Tom_L: well, either way i'm not swapping back again
07:40 PM Tom_L: surely 2x the ram wouldn't do that would it?
07:40 PM lcnc-relay: <skunkworks8841> I have not seen that..
07:41 PM xxcoder: I know that ram does require some stuff but my knowledge is very old
07:41 PM lcnc-relay: <skunkworks8841> well - is it 2 sticks vs 1? then hyes
07:41 PM lcnc-relay: <skunkworks8841> yes
07:41 PM lcnc-relay: <skunkworks8841> if you have a motherboard that supports dual data rate ram? 2 sticks will perform better than 1
07:41 PM lcnc-relay: <skunkworks8841> I have seen that.
07:41 PM lcnc-relay: <skunkworks8841> (I don't know if that is the term)
07:44 PM xxcoder: ram refreshing. dont know
07:44 PM xxcoder: I know years ago it takes small percentage of cpu time but like I said my knowledge is quite obselete
07:46 PM Tom_L: i could swap memory if need be
07:46 PM Tom_L: 4 sticks vs 2
07:46 PM xxcoder: do they even sell static ram nowdays?
07:46 PM xxcoder: rather than dynimatic
07:47 PM Tom_L: sure
07:47 PM xxcoder: interesting
07:47 PM Tom_L: it must be the ram or something because the problem just swapped PCs
07:48 PM Tom_L: getting good latency on the main pc now and crap on the test pc
07:51 PM xxcoder: interesting indeed
07:52 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/latency_main_pc.png
07:52 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/latecncy_test_pc.png
07:52 PM Tom_L: it's not the cpu
07:52 PM Tom_L: i'll swap ram and see what that does
07:55 PM lcnc-relay: <skunkworks8841> wow - that is bad..
07:55 PM lcnc-relay: <skunkworks8841> so not symetrical..
07:56 PM xxcoder: yeah
07:59 PM Tom_L: swapping ram didn't seem to do much
07:59 PM Tom_L: no clue
08:00 PM Tom_L: i've swapped cpu mb and ram
08:01 PM Tom_L: both histograms still look about the same
08:01 PM Tom_L: it's a smaller psu?
08:05 PM Tom_L: same bios version
08:06 PM xxcoder: ram latency settings?
08:09 PM Tom_L: those all look the same
08:10 PM rdtsc is now known as rdtsc_away
08:14 PM xxcoder: drat not sure then
08:29 PM Tom_L: heh swapping psu did nothing
08:30 PM xxcoder: kinda doubted it but good to know
08:34 PM lcnc-relay: <skunkworks8841> but swaping out cases is the only thing?
08:34 PM Tom_L: so far
08:34 PM lcnc-relay: <skunkworks8841> that is very weird
08:34 PM Tom_L: hah
08:34 PM xxcoder: any heat issues?
08:34 PM Tom_L: you're tellin me
08:34 PM Tom_L: no
08:34 PM xxcoder: it would trottle
08:34 PM Tom_L: i swapped mb...
08:35 PM lcnc-relay: <skunkworks8841> onboard video?
08:35 PM xxcoder: yeah not sure whats happening there
08:35 PM Tom_L: if the chip fan wasn't seated it would follow
08:35 PM Tom_L: both using onboard video
08:35 PM Tom_L: identical mb
08:36 PM Tom_L: oddly enough the one with 4 sata devices plugged in has the best latency
08:36 PM Tom_L: the test pc only has 1
08:36 PM lcnc-relay: <skunkworks8841> smart test the hard drive?
08:36 PM Tom_L: wait.. the main one only has 3 actually plugged in
08:36 PM Tom_L: it
08:36 PM Tom_L: it's a new ssd
08:36 PM lcnc-relay: <skunkworks8841> ok
08:37 PM xxcoder: my pc is slow on heavy disk accesses because hd is dying, didnt realize it till I briefly had new hard drive and it was a lot faster
08:37 PM Tom_L: i did a ls -lF /dev/disk/by-id to list them
08:37 PM lcnc-relay: <skunkworks8841> (I have had a hd going bad cause bad latency)
08:38 PM xxcoder: too bad new drive cooked itself :( its on way back
08:38 PM xxcoder: voice coil area got very hot
08:38 PM Tom_L: the goal is to test flexgui on hardware... i doubt i run any parts. maybe it'll behave long enough to run a few tests
08:38 PM pcw-home: what hardware changed between the two plots?
08:39 PM pcw-home: (other than the CPU)
08:39 PM Tom_L: ssd are different but same brand and era
08:39 PM Tom_L: the new one is an evo860 the old one is an evo850
08:39 PM Tom_L: samsung
08:39 PM xxcoder: uh isnt those have bad ded drive run
08:39 PM Tom_L: i have an evo870 around here somewhere
08:40 PM Tom_L: tried swapping ram psu etc etc
08:40 PM Tom_L: it must just like sitting under the desk
08:40 PM pcw-home: same MB?
08:40 PM Tom_L: both are the same with the same bios version
08:41 PM pcw-home: same BIOS settings?
08:41 PM Tom_L: the cpu is i5 but different speed
08:41 PM Tom_L: yes
08:41 PM xxcoder: wonder if you used live usb on both with no ssd, would there be any difference
08:41 PM Tom_L: but i've gotten good latency with both cpu in the main pc box
08:41 PM Tom_L: very odd
08:41 PM Tom_L: and it was good sitting on the desk with no box
08:43 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/temp/Test_pc.jpg
08:43 PM Tom_L: got great latency like that
08:43 PM Tom_L: :)
08:44 PM xxcoder: nice cardboard case ;)
08:44 PM xxcoder: man cant wait to get my new nvme
08:45 PM Tom_L: i'll try swapping ssd tomorrow and see what that does
08:45 PM Tom_L: that's about the only thing i haven't swapped
08:46 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/RTAI_TEST/RTAI_I5_Histogram.png
08:47 PM Tom_L: that was this board running RTAI but flexgui won't run under RTAI
08:47 PM Tom_L: and neither will ethernet mesa boards
08:48 PM Tom_L: where and how do you set isolcpus?
08:48 PM Tom_L: in the kernel?
08:48 PM Tom_L: or is that a debian setup setting?
08:49 PM lcnc-relay: <skunkworks8841> Tom_L: I think those valve boxes will do just fine..
08:49 PM lcnc-relay: <skunkworks8841> I just won't burry them flush (and find the biggest ones)
08:49 PM Tom_L: right
08:52 PM lcnc-relay: <skunkworks8841> menards has some in stock
08:52 PM lcnc-relay: <skunkworks8841> https://www.menards.com/main/outdoors/watering-irrigation/underground-sprinkler-systems/underground-sprinkler-valves-boxes/nds-reg-14-x-19-irrigation-valve-box-with-overlapping-cover/113bc/p-1444448951300-c-8670.htm?exp=false
08:53 PM Tom_L: if you had a local irrigation supply they'd probably have more for less
08:54 PM lcnc-relay: <skunkworks8841> I wonder if my leaf blower would blow out the nuts in those 4 inch tubes 😉
08:54 PM Tom_L: a magnet would
08:55 PM Tom_L: got an old hdd?
08:55 PM lcnc-relay: <skunkworks8841> um.,. hickery nuts..
08:55 PM Tom_L: oh
08:55 PM lcnc-relay: <skunkworks8841> and oak
08:55 PM Tom_L: :)
08:55 PM lcnc-relay: <skunkworks8841> took me a second..
08:55 PM Tom_L: stick a vacuum hose down em first
08:55 PM Tom_L: shop vac
08:56 PM pcw-home: Tom_L isolcpus is set in the kernel command line (with grub)
08:56 PM lcnc-relay: <skunkworks8841> they are 100 fut foot runs
08:56 PM lcnc-relay: <skunkworks8841> give or take
08:56 PM Tom_L: right but the nuts would likely be at the start of the opening
08:56 PM lcnc-relay: <skunkworks8841> oh - maybe..
08:56 PM Tom_L: alot of them
08:56 PM Tom_L: then get the leaf blower out for the remainder
08:57 PM lcnc-relay: <skunkworks8841> well - this project doesn't seem so bad now..
09:00 PM pcw-home: kernel command line on this machine:
09:00 PM pcw-home: quiet splash intel_idle.max_cstate=1 processor.max_cstate=1 idle=poll intel_idle.max_cstate=1 i915.enable_dc=0 isolcpus=3 i915.enable_rc6=0

09:01 PM pcw-home: etc/default/
09:02 PM pcw-home: so cd /etc/default

09:04 PM Tom_L: all that's there now is GRUB_CMDLINE_LINUX_DEFAULT="quiet"
09:04 PM pcw-home: edit, save, then sudo update-grub
09:04 PM Tom_L: right
09:04 PM Tom_L: a tomorrow project
09:05 PM pcw-home: of course isolcpus=3 is just for 4 core CPUs
09:05 PM Tom_L: yeah this has 4 cores iirc
09:05 PM _unreal_: ok more wiring done
09:05 PM _unreal_: My siblings have been here all day
09:05 PM _unreal_: no fighting amazlingly
09:06 PM -!- #linuxcnc mode set to +v by ChanServ
09:06 PM _unreal_: and got a good amount of stuff sorted and tossed
09:06 PM pcw-home: but your latency is so bad I expect its something else
09:06 PM Tom_dev: i've no idea what
09:06 PM pcw-home: yeah fairly mysterious
09:07 PM Tom_dev: may go blow the dust out... can't hurt
09:07 PM pcw-home: Thats what an optimist thinks...
09:08 PM _unreal_: I wish my asus tinkerboard wasnt so damn un-stable I would have loved to use it as my lcnc puter
09:08 PM pcw-home: I guess I should be an optimist, my git login issue went away when I re-booted
09:08 PM _unreal_: I had gotten it setup with lcnc. but its problems with booting. boot loop failures
09:09 PM _unreal_: pcw-home, "git"err done
09:10 PM pcw-home: I ws about to give up for the day since I did not wany to mess with gits two step login junk today
09:10 PM pcw-home: s/gits/githubs/
09:11 PM Tom_dev: gonna give it a try..
09:14 PM Tom_L: 43us so far
09:15 PM Tom_L: the pattern looks odd though
09:15 PM Tom_L: i'll take a snapshot here in a bit
09:17 PM Tom_L: pcw-home, what do you make of this? http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/grub_mod_i5.png
09:20 PM lcnc-relay: <TurBoss> is this a realtime kernel?
09:20 PM Tom_L: yes
09:20 PM lcnc-relay: <TurBoss> ookay
09:20 PM Tom_L: 6.1 iirc
09:20 PM lcnc-relay: <skunkworks8841> Wow.. still.. that latency histogram is odd looking
09:20 PM Tom_L: heh leave it to me
09:20 PM pcw-home: Most of that is off screen, you might try latency-histogram -sbinsize 2000 -bbinsize 2000
09:22 PM lcnc-relay: <skunkworks8841> What does u name -a say?
09:22 PM -!- #linuxcnc mode set to +v by ChanServ
09:23 PM Tom_dev: Linux debian12 6.1.0-20-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.85-1 (2024-04-11) x86_64 GNU/Linux
09:23 PM Tom_L: wtf is dynamic??
09:23 PM lcnc-relay: <TurBoss> looks like a regular kernel
09:23 PM Tom_L: maybe i need to double check preempt-rt
09:24 PM pcw-home: Yeah missed that on your plots (it does not say "rt" on the bad plot)
09:24 PM lcnc-relay: <skunkworks8841> Formally there would be an rt in there somewhere
09:24 PM lcnc-relay: <skunkworks8841> *normally
09:25 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/grub_mod_i5.png
09:25 PM lcnc-relay: <TurBoss> if its installed may be hidden in the grub menu
09:25 PM lcnc-relay: <skunkworks8841> I missed that too..
09:25 PM Tom_L: that's with pcw-home's histogram settings
09:25 PM Tom_L: i'll go fix the kernel....

09:26 PM lcnc-relay: <TurBoss> "Linux turbostich 6.6.34-rt32-turbo-v8+ #19 SMP PREEMPT_RT Thu Jun 20 04:07:43 CEST 2024 aarch64"
09:26 PM lcnc-relay: <TurBoss> 😆
09:26 PM lcnc-relay: <skunkworks8841> See how it says 6.1.61-rt15
09:27 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/kernel_selected.png
09:27 PM Tom_L: i wonder if it booted the wrong one
09:28 PM lcnc-relay: <TurBoss> then grub has choose the default one
09:29 PM -!- #linuxcnc mode set to +v by ChanServ
09:29 PM Tom_dev: Linux debian12 6.1.0-18-rt-amd64 #1 SMP PREEMPT_RT Debian 6.1.76-1 (2024-02-01) x86_64 GNU/Linux
09:29 PM pcw-home: I think grub will choose the newest (which is not RT)
09:29 PM Tom_dev: i thought once you selected it, it stuck
09:30 PM pcw-home: not sure
09:30 PM lcnc-relay: <TurBoss> check /etc/default/grub
09:32 PM Tom_dev: ok it's looking more like it should now
09:32 PM Tom_dev: give it a few and i'll post it
09:32 PM lcnc-relay: <TurBoss> hurray!
09:32 PM Tom_dev: damn... what a day
09:36 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/preempt-rt.png
09:36 PM Tom_L: better
09:40 PM Tom_L: running the default grub settings now that i have preempt-rt right
09:43 PM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/default_grub.png
09:43 PM Tom_L: that's more like it
09:43 PM Tom_L: and that's why we run RT kernels :)
09:44 PM xxcoder: so one was rt and other preempt? or was that same thing
09:44 PM Tom_L: one wasn't rt
09:44 PM xxcoder: so it heavily affected latency eh
09:44 PM Tom_L: dunno why grub decided to boot from it since i'd selected preempt-rt previously
09:45 PM xxcoder: interesting. well problem solved! nice
09:45 PM Tom_L: i don't remove them all from grub in case i botch a kernel messin around
09:45 PM Tom_L: then i still have one to fall back on
09:45 PM Tom_L: from experience...
09:46 PM xxcoder: yep always have a fallback
09:47 PM Tom_L: solving problems that shouldn't have been problems...
09:49 PM Tom_L: still running.. max us 24
10:00 PM lcnc-relay: <skunkworks8841> Now that looks like a normal latency graph...
10:04 PM Tom_L: that's with no grub mods
10:04 PM Tom_L: tried both ways and it didn't seem to make much difference
11:10 PM lcnc-relay: <big_kevin420> those are pretty good numbers
