| wertigon | But might need a reconfigure of that; not sure | 09:19 |
| wertigon | Oh, and using thud | 09:19 |
| wertigon | What are we supposed to use instead of meta-toolchain to build a toolchain? populate_sdk? | 09:19 |
| letothe2nd | yep, the recommended way these days is building the sdk | 09:20 |
| wertigon | Ok :) | 09:20 |
| wertigon | Planning to do that anyway, just want to get the toolchain to work first. I can populate_sdk without mingw. | 09:21 |
| *** frsc <frsc!~frsc@i4DF677E4.static.tripleplugandplay.com> has quit IRC | 09:21 | |
| letothe2nd | i think thats the wrong approach. meta-toolchain might be broken where the sdk isn't | 09:22 |
| wertigon | Will try populate_sdk then | 09:27 |
| wertigon | But not too hopeful | 09:27 |
| letothe2nd | and really, that stack is big. start small, iterate. find out where things stop working | 09:28 |
| wertigon | letothe2nd: Everything but mingw compiles | 09:31 |
| wertigon | Already tried it | 09:31 |
| letothe2nd | no, i don't think so. what you probably tried is "what compiles for non-mingw" | 09:32 |
| letothe2nd | this doesn't mean that things that compile this way still compile for mingw | 09:32 |

| wertigon | So, I get meta-openembedded from that repo | 09:49 |
| wertigon | Not openembedded-core | 09:49 |
| rburton | the mingw layer back in thud was very limited | 09:50 |
| rburton | maybe you're hitting the edge of its support | 09:51 |
| rburton | so i've just fired a meta-toolchain for mingw here on thud to see what happens, but i also have pilates now so i'll be gone for a bit | 09:52 |
| wertigon | rburton: It is quite possible, yes | 09:53 |
| wertigon | rburton: We are following ti release cycle, so thud will soon become next layer. I'll try to include openembedded-core as it's separate layer and report back if it works. | 09:53 |
| rburton | that said meta-toolchain is what i expected to work. | 09:54 |
| rburton | no, you must have oe-core from somewhere else already | 09:54 |
| wertigon | Ok | 09:54 |
| rburton | you literally can't build without it | 09:54 |
| wertigon | I see :) | 09:54 |

| letothe2nd | GeneralStupid: depends on what you mean by "configuration" | 10:22 |
| letothe2nd | but often, "yes" | 10:22 |
| wertigon | Another thing to note; each git pull creates it's own mirror, it is possible to clone a new repository from your machine over ssh for instance | 10:23 |
| wertigon | So you could in theory only clone all repositories. Of course, they will need to be updated manually from time to time | 10:24 |

| kpo | i'm not sure if I understood you correctly | 10:57 |

| GeneralStupid | Ok, i created my own layer and i used the bbappend. Ist there a way to modify and not override SRC_URI? | 12:56 |
| GeneralStupid | (and not only append ;) ) | 12:57 |
| wertigon | rburton: Can I build a simple test image that omits most of my code? E.g. is it possible to build poky-minimal -c populate_sdk? | 12:58 |
| rburton | you can build any image for populate_sdk | 12:58 |
| rburton | start with meta-toolchain though, that works here | 12:58 |
| wertigon | Yeah, meta-toolchain fails :P | 12:58 |
| rburton | where does that fail | 12:58 |
| wertigon | Somewhere in mingw, exact place I cannot say more than the packages given above | 12:59 |
| wertigon | But I have not omitted any layers right now - if I omit everything but meta-openembedded stuff and mingw, it should work yes? | 13:00 |
| rburton | well ncurses isn't part of meta-toolchain | 13:00 |
| rburton | neither is openssl | 13:00 |
| rburton | so what one precisely is failing | 13:00 |
| kpo | paulbarker: wee, the way I linked to on stackoverflow worked :) thank you for help! Now, I have to merge it with update system, rauc :) | 13:01 |
| wertigon | https://pastebin.com/yJUnZHej | 13:01 |
| wertigon | rburton: Those are the error messages I got last time I tried, right now I did a populate_sdk -k and waiting for that to finish | 13:03 |
| rburton | wertigon: looks like something in your distro is adding those to meta-toolchain then | 13:03 |
| rburton | as they're not in mine | 13:03 |
| rburton | maybe meta-arago is breaking things | 13:04 |
| rburton | relatively easy test is to do just poky thud + meta-mingw thud, build the toolchain | 13:04 |
| wertigon | Hmm, yeah | 13:04 |
| rburton | assuming that works - which it should as it works here - then you've at least isolated it to something in your config | 13:04 |
| rburton | add meta-arago and see if that breaks | 13:05 |
| wertigon | Ok, so I basically strip all layers but poky, openembedded and meta-mingw for a starter? | 13:05 |
| wertigon | Once my current failbuild is complete that is :P | 13:06 |
| letothe2nd | 09:17 < letothe2nd> other than that, i can only say, start with poky only, try, add layers one after the other. that stack is rather big after all, hard to say where things go wrong | 13:06 |
| letothe2nd | literally 4 hours ago | 13:06 |
| wertigon | Yeah, I know | 13:06 |
| rburton | yeah what letothe2nd said :) | 13:06 |
| rburton | start from scratch, poky + meta-mingw, new build dir | 13:06 |
| letothe2nd | thanks for not listeing. | 13:06 |
| rburton | point at your DL_DIR etc | 13:06 |
| rburton | set machine to qemuarm, sdk to mingw. | 13:07 |
| wertigon | letothe2nd: Sorry, thought I was only missing a host package or somesuch, but turned out I was wrong | 13:07 |
| rburton | fwiw i'm in two chats simultanously moaning about arago :) | 13:07 |
| wertigon | Yeah, it isn't the best that yocto provides, this is very true. :) | 13:08 |

| wertigon | rburton: In meta-arago-distro/conf/layer.conf remove linaro-toolchain and meta-optee from LAYERDEPENDS_meta_arago_distro | 14:29 |
| wertigon | rburton: And in meta-arago-extras/conf/layer.conf remove linaro-toolchain from LAYERDEPENDS_meta-arago-extras | 14:30 |

| Crofton|work | denix, common problem :) | 17:09 |
| denix | Crofton|work: that open cl stuff is quite old, based on llvm version that was never in oe-core. it's being worked on to update it to a recent llvm from oe-core - that would allow it to be detached from arago and be in meta-ti bsp only | 17:10 |

| Crofton|work | and that is the gap the developers need to be working on bridging | 18:35 |
| JPEW | denix: IIRC, you can put multiconfig files in layers now | 18:35 |
| JPEW | So, I think you can stuff the pre-canned DSP multiconfig and ancilliary processors in your layer for others to use | 18:36 |
| denix | JPEW: ok, that would be great, need to experiment again with mc - it's been a while since last time | 18:37 |
| JPEW | denix: It's gotten a lot better | 18:37 |
| denix | JPEW: what about the glue config? having all separate processor configs available is useless, if they are not automatically and properly bound together by BSP layer config... | 18:39 |
| JPEW | denix: Sorry, not quite sure I follow, can you clarify? | 18:40 |
| fray | If you are treating the DSP as something the YP can build for (vs just include this firmare blob and driver into your image).. then a hetergeneous (multiconfig) may make sense | 18:40 |
| fray | Something I'm currently working on trying to define after OEDEM.. just havn't had time to put the thoughts together and sent it to the oe-architecture mailing list yet | 18:41 |
| denix | JPEW: say, I got all separate configs for DSPs, MCUs and GP cores, how do I now bind them all together into a single SOC machine? | 18:41 |
| denix | fray: yeah, discussing multicore specifically for this - to build pieces of hetergeneous SOC | 18:42 |
| fray | What I'm looking at suggesting is effectively: | 18:43 |
| JPEW | denix: You can define dependencies between multiconfigs using "mcdepends"... effectively is allows a given task in a recipe from one multiconfig depend on a recipe/task in another multiconfig | 18:43 |
| fray | System (or board) is the local.conf | 18:43 |
| fray | then there are one or more 'multiconfig' .confs for each thing the yocto project can target.. linux, freertos, etc.. | 18:43 |
| fray | the system/board can then (via dependencies) control what is built, and call wic (or other tooling) to assemble the final image for deployment via whatever mechanism.. | 18:43 |
| fray | i.e. sd card, multiple partitions for each component | 18:44 |
| JPEW | There are lots of ways to use mcdepends; one "simple" way is to make your final image recipe mcdepend on the DSP target binary recipe/task, then shove it into the image in the proper path... but there are better ways also. | 18:44 |
| denix | fray: that's exactly my point - why is the local.conf defines the system/board? it should be conf/machine/<blah>.conf | 18:44 |
| fray | add this this the concept of a system (or board) device tree.. the primary local.conf (system machine) can use this and to define the configurations and dependecies dynamically.. | 18:44 |
| fray | local.conf: MACHINE = 'myboard.conf' | 18:45 |
| fray | multiconfig/xilinx_a15.conf | 18:45 |
| fray | multiconfig/xilinx_a72.conf | 18:45 |
| fray | each would have their own 'MACHINE defined'.. | 18:45 |
| JPEW | fray: A repository that has some multiconfig examples would be great | 18:45 |
| fray | and then local.conf uses dependencies to pull in those based on the system device tree | 18:45 |
| denix | JPEW: yeah, also looking for examples | 18:45 |
| fray | JPEW, first order of business is email to architecture list.. examples will come after we get a few things figured out.. | 18:46 |
| fray | the issue right now is nobody has standard terms for this, so just discussing it people don't understand what we're discussing | 18:46 |
| fray | If I could get over the cold I got right after Lyon, I'd construct and send the initial email to get started.. | 18:46 |
| JPEW | I gave a talk that had some multiconfig information at the platform security summit.... doesn't look like the video is up yet though. | 18:47 |
| denix | my biggest concern is that multiconfig lives in conf/ and is driven by local.conf, which is all user-owned. I want my BSP layer to define all multiconfig/ files and bind them together by a MACHINE | 18:47 |
| fray | denix, it can certainly work that | 18:47 |
| fray | I've got ideas on how, without any change to bitbake.. | 18:47 |
| fray | MACHINE is the unit of definition for "what is being built".. So a machine is one component of a heterogenous configuration.. I keep hearing them called "sub-machines" or "soc components" or... it's MACHINE.. cause that is the term we have, and we don't want to redefine it.. we just need to clarify it's usage/meaning.. | 18:48 |
| fray | we need a level 'above' machine to define a system or board.. | 18:48 |
| denix | fray: so, what I'm looking for is local.conf only sets MACHINE=soc1 and BSP layer pulls all necessary multiconfig/* files automatically for that MACHINE. then you switch MACHINE=soc2 and BSP pulls another different set of multiconfig/* files automatically | 18:48 |
| fray | that way machine can stand alone.. and the system/board does the things above it | 18:49 |
| fray | board says: I have these 'machines' on it.. and then the appropriate multiconfigs are brought in based on that.. | 18:49 |
| denix | sure, another level to define BOARD that pulls multiple MACHINE configs would also work | 18:50 |
| aehs29 | denix: yeah its gotten a lot better, after I talked with Richard, I think they can be dfined on layer.conf as well | 18:50 |
| fray | I think I know the 'how', but we need to define a few things first | 18:50 |
| aehs29 | and I'm working on fine tuning the multiconfig work to be more user friendly for SOCs | 18:50 |
| aehs29 | hopefully for th next release | 18:50 |
| fray | yup, that will help.. | 18:50 |
| aehs29 | I will merge the multiconfig example on meta-freertos later today btw | 18:51 |
| fray | the big thing for me, is I want it driven (how the 'machines', components of the board, are wired and shared resources to define the settings without having to implement 100 different machines for all possible configurations) | 18:51 |
| fray | thus I want the main board to be able to define the configurations for the machines.. the machines (for this) could be loosely defined, with specific definitions coming from a system/board DTB | 18:51 |
| denix | fray, aehs29: sounds promising | 18:52 |
| fray | i.e. a board has 4 cortex a72 cores.. I don't want 4 machines.. I want 4 multiconfigs to use the same 'machine' with 4 variants (in other the ways these things are wired up) | 18:52 |
| fray | ...4 variants (in only the ways...) | 18:53 |
| denix | let's move the discussion to oe-architecture list | 18:53 |
| aehs29 | I think it would definitely be something useful for heterogeneous archs, which a lot of people are using, probably the most difficult part will be on agreeing on what we'd call it, BOARD, SYSTEM?, SOC?, I'll try to get something working and send an RFC to see what people think | 18:53 |
| fray | I swear this cold is making my typing even worse then normal | 18:53 |
| fray | and with heterogenous computing, I'm leaning toward system.. because it might be multiple "boards" that all share resources.. | 18:54 |
| aehs29 | denix: sounds good | 18:54 |
| RP | denix: just to be clear, you can define multiconfigs in your layer now | 18:55 |
| aehs29 | fray: true, system just seems too generic | 18:55 |
| fray | it does, but in many ways system MIGHT be the right level.. | 18:56 |
| aehs29 | true as well | 18:56 |
| fray | but that's why we need the discussion.. it might turn out board is the right level | 18:56 |
| denix | RP: would that be layer.conf? | 18:56 |
| denix | fray, aehs29: do we need a different entity for system/board? can we re-use MACHINE to be hierarchical? | 18:57 |
| fray | re-use machine | 18:57 |
| fray | we could certainly defined say 'SYSTEM' or 'BOARD', but under the hood, it should just become machine and use the existing machine wiring in everything | 18:57 |
| fray | again, need to figure that out.. | 18:57 |
| aehs29 | denix I think you just asked the right question, I just dont want to break MACHINE functionality | 18:58 |
| denix | fray: yeah, conf/soc.conf to pull conf/a72.conf and conf/dsp.conf and conf/mcu.conf, etc | 18:58 |
| fray | exactly.. I don't want 'sub machines'.. and I don't want to break anything existing | 18:58 |
| denix | on the other hand, multiconfig specifies things like distro, libc, etc... | 18:59 |
| fray | which is exactly what we want.. like I said, heterogeneous computing.. not 'this thing has a .... and we just need Linux to load firmware onto it'.. that is traditional firmware model | 18:59 |
| fray | some cores might be FreeRTOS, some might be musl, and some might be full on glibc like stacks.. (and some might even be containers) | 19:00 |
| fray | but nothing here should prevent a developer from working on a 'piece' of the stack using the right MACHINE and associate configs.. it's the system builder that puts it together | 19:00 |
| * fray needs luck.. bbiab | 19:01 | |
| RP | denix: here is a simple example: https://paste.debian.net/1116099/ | 19:03 |
| RP | denix: in this case I've chosen to add multconfigs to a distro, where one even references another subclass. You can then do "bitbake mc:musl:bash" or "bitbake bash" | 19:04 |
| RP | it won't quite work since you need to set TMPDIR to be non-overlapping but you get the idea - its entirely contained in the distro layer | 19:05 |
| RP | denix: you could do something with machines in a BSP in much the same way | 19:05 |
| RP | with some TMPDIR values in the multiconfig, this would work | 19:05 |
| denix | RP: oh, this is nice! so, if I set TMPDIR="tmp-${DISTRO}-${LIBC}" it would separate them properly, right? | 19:07 |
| RP | denix: yes | 19:08 |

| letothe2nd | interesting what i seem to have triggered at YPS/OEDEM. i actually think of meta-ti as one of the "good" BSPs, even tried to use it as explanation vehicle during my doomed live session yesterday | 19:52 |
| *** letothe2nd is now known as LetoThe2nd | 19:52 | |

| denix | LetoThe2nd: ha, never underestimate people's ability to demean everything around! :) | 19:58 |
| LetoThe2nd | the things that really deserve a beating are like, a bsp that forces you to use a baked in distro enable the universe and everything beynod | 20:00 |
| LetoThe2nd | for the bbb i can add meta-ti and set machine. voila, i get a build inluding wic.xz | 20:00 |
| LetoThe2nd | i think we can all agree on more complex cases being more complex, but for starting out it is quite wellbehaved, IMHO. | 20:01 |
| denix | and more complex features are not yet fully or easily supported - see the above discussion on multiconfig for example... | 20:02 |
