CarlFKtumbleweed: the 2 nics end in 89:49 and 7f:7a00:18
CarlFKuplink is :7a00:18
CarlFKonboard is 4900:19
tumbleweedCarlFK: that's useless because only one of them has attempted to DHCP00:25
tumbleweedbut I have a photo :)00:25
CarlFKmoved cable, dhclient -ed00:28
mithro_florent_: When using a GPIOOut object, if I hand it a signal which has a Signal(reset=1) - as far as I can see in the code it should get a reset signal of 1 right?00:37
mithro_florent_: Don't worry, I just inverted the signal a little00:46
_florent_mithro: ok00:47
_florent_mithro: what are you doing with your GPIOOut?00:47
_florent_mithro: is your DHCP working now?00:47
mithro_florent_: No, my DHCP isn't working00:47
mithro_florent_: GPIOOut is for the fx2_reset / tofe_reset signals00:48
_florent_mithro: ok, ping me when you want to debug your DHCP00:48
_florent_mithro: it seems you only have a byte shift or something like that00:48
mithro_florent_: What are you working on at the moment?00:49
_florent_mithro: nothing, sending photos from Australia to family and friends...00:49
_florent_mithro: but if you have something to do I can :)00:49
mithro_florent_: Ahh okay, if you are taking a break for now we can start after lunch, good to do that so we don't get burnt out :-P00:49
mithro_florent_: Otherwise, I might get you to start looking at the dvisampler / phase delay timeout issue?00:50
mithrojea: Where are we at with the many build script thingy?00:50
jeamithro: I think it is working. Should be a link above (last night)00:51
_florent_mithro: for now maybe we should stop adding feature and at least make some testing00:51
mithro_florent_: Yeah, I'm about to flash a bunch of opsis00:52
_florent_mithro: I'd like to know if the misoc/migen merge into LiteX is not introducing regressions00:52
_florent_mithro: ok00:52
_florent_mithro: are you using upstream LiteX?00:52
mithro_florent_: Yes00:52
_florent_mithro: ok good00:53
_florent_mithro: you have some video output? (video output was not working on my side but I was wondering if it was my setup or not)00:53
mithrojea: Can you set things building and see if you can failures / successes on the current head? (That I just pushed)00:57
mithrojea: Or about to push00:58
jeamithro: do we have a physical machine I can use for that so it goes faster?00:58
mithrojea: Does the build take much longer in your virtual machine then on mine?00:58
mithrojea: But sure, we can set up a machine if you want?00:59
jeathe current build is taking a while, but i just realised it might have not had TARGET=video set00:59
jeaprevious builds were ~15min00:59
mithrojea: occasionaly the gateware gets confused and will never complete00:59
mithrojea: Can you put like a 45 minute timeout in your script and mark that build as a "compile fail"01:00
mithrojea: It would be awesome if we could get my turbo doing this testing -- no idea how hard that is to do01:00
mithrojea: Maybe that is something for next week01:00
mithro(The Turbo that is)01:00
jeaI can probably add a timeout in. Haven't looked up how yet01:00
jeawhat is a Turbo?01:00

micolousYeah, got it.02:14
mithro_florent_: Did you get anywhere with the color issue?02:31
_florent_mithro: no, I'd like we test first with gstreamer and reducing ranges for colors components02:33

xfxfmicolous: were you testing all of the boards?  i want to get that done before we start making up kits this evening so we know what we're putting where04:23
xfxfmithro: venue only has 42" plasma confidence monitors, most rooms are too small to put them in.  there's 2x confidence monitors in the plenary + i've asked the dude to configure it so there's a HDMI from it going back to our opsis's... so those ones will do 2x outputs, others only need to do 1x04:24
mithromicolous: went for a walk while I ate lunch04:25
xfxfmithro: the thing where I needed to connect the ethernet to load new firmware on my board - is that a known issue / going to be fixed / etc?04:27
xfxfi'd like to stick the one i pulled apart back in its case, ethernet won't fit if I do that04:27
mithroxfxf: that should already be fixed. But we need Ethernet if you want to load Chris's images04:28
xfxfmithro: i'm wondering whether we skip on that for this event (for the podium the venue video mixer has an additional video in we can plug a dedicated laptop into).  super useful feature, but we also need to code an additional script + train volunteer on switching the inputs and loading the image - can see human error occurring04:29
xfxfnone of which is hard but takes time we don't have right now04:29
xfxfplus issue with cases (ethernet not fitting unless we hack up a cable)04:30
mithroI don't think we need to train anyone? We can load from the noc?04:32
mithroThe script or written04:32

xfxfonly choice is a $42 steak08:46
xfxffuck it08:46
xfxfit better be a good steak08:46
mithro_florent_ doesn't do seafood either?08:46
xfxfseafood is pretty much the only thing i don't eat08:47
xfxfwell, apart from garbage08:47
tumbleweednext options:
mithro_florent_ is there anything at you can eat?08:47

CarlFKI like food.08:49
xfxf2 mins, gonna commit up stuff08:49
xfxfwe should get french so _florent_ can tell us how terrible australia's idea of franch food is :P08:50

xfxfit's super rough, will modify it to take arguments etc, but it works11:46

jeatumbleweed / CarlFK - what does this output on the server?11:51
jeagrep vm.max_map_count /etc/sysctl.conf11:51
tumbleweedwe aren't doing anything special there11:52
tumbleweed(the default, not specified in sysctl.conf)11:52
jeaelastic search is telling me "The vm_max_map_count kernel setting needs to be set to at least 262144 for production use"11:53
jeaI don't know if I care about production use though for this11:53
tumbleweedheh, yes second google result for max_map_count is an elastic search page11:54
jeaThinking about it, I may as well just use it as development/testing. that is all I am doing anyway!11:54
CarlFKI think we want something between enterprise and web scale11:54
jeawe should deploy CoreOS to make sure we have a good setup11:55
tumbleweedjea: I'm perfectly happy to increase it, it seems safe enough11:55
vystrela+1 LGTM11:56
* tumbleweed bumps it11:56
tumbleweedwe only have 8GB of RAM, so don't eat it all11:57
tumbleweedmicolous: where is the streaming going to run? on each mix box?11:58
* tumbleweed is now thinking that RAM may get tight11:59
jeaah, that could be an issue11:59
jeathe other things sound small, but elastic search seems large :(11:59
vystrela8GB might not be enough now that it's running software written by millennials11:59
vystrela640k doesn't quite cut it12:00
xfxfelasticsearch is frigging huge12:00
xfxfit's java too IIRC12:00
tumbleweedjava is simple, it just uses whatever you give it12:01
tumbleweedall of it12:01
tumbleweeddo we think we have more data that grep can handle? (just saying...)12:03
vystrelaan awkward amount of data12:03
vystrelaas in, an amount of data you'd use awk for12:03
