| mntmn | yeah | 00:02 |

| swivel | mntmn: oh, my mistake, i just did a quick ddg for imx8m and saw 14nm in the results | 00:26 |
| Kooda | Quick question, in case anyone knows offhand: can the M4 core access the whole memory and external devices? | 01:30 |
| mntmn | Kooda: i don't know... yet | 01:36 |
| mntmn | > The Cortex-M4 processor has a modified 32-bit Harvard bus architecture | 01:39 |
| mntmn | > sing a 32-bit | 01:39 |
| mntmn | address space, low-order addresses (0x0000_0000 through 0x1FFF_FFFF) use the Processor Code (PC) bus, and high-order addresses (0x2000_0000 through 0xFFFF_FFFF) use the Processor System (PS) bus. | 01:39 |
| mntmn | haha there's a "Backdoor port" going via CCM to a crossbar switch... | 01:40 |
| mntmn | > SRAM controller requests from all other bus masters on the backdoor port | 01:40 |
| mntmn | it has 256kB tightly coupled sram | 01:42 |
| Kooda | Hehe well, at least the intent is clear… I guess it has to, for the “trusted computing” things | 01:42 |
| Kooda | s/things/use cases/ | 01:42 |
| Kooda | My initial question was asked because I’m wondering what this core could do by itself, for example when the system is “off”, to keep some simple things running (of course not programs from the main system). | 01:48 |
| Kooda | Maybe things like staying active as a wifi access point to share files locally while the Reform stays in a bag ^^ | 01:49 |
| mntmn | yeah, interesting questions. not sure if PCIe etc can be mapped into its address space though | 01:51 |

| lastebil | mntmn: so I'm attempting to build the userland2 parts on the reform2 in void; | 12:17 |
| lastebil | is there any reason you have not made your own local repo for mesa and applied the patches there? | 12:17 |
| mntmn | lastebil: neat! | 12:18 |
| lastebil | (I've broken the parts into individual build scripts now, for simplicity and also because each package is having slightly different issues, so I'm doing a lot of "no, I don't want to patch again. no. no I don't want to patch again. NO. NO I DO NOT WANT TO PATCH AGAIN" (: | 12:18 |
| lastebil | I have drm built, and mesa, but having issues with wlroots as there is no egl binary; somehow I think it _should_ exist after the mesa build step? | 12:19 |
| mntmn | lastebil: no egl binary? | 12:56 |
| mntmn | lastebil: ah maybe ldconfig /usr/local/lib | 12:56 |
| lastebil | yeah. no egl binary. does it come from mesa-utils on debian or is it actually built in the mesa step? | 13:01 |
| lastebil | I'm going to try re-running the mesa build with a fresh git pull, and have it redo the patches, and all in one step, and look for errors again | 13:03 |
| mntmn | lastebil: i have no idea what an egl binary is. do you have exact error messages? | 13:30 |
| Kooda | mntmn: I suspect they are talking about eglinfo, es2gears, etc | 13:32 |
| Kooda | Though that would be weird hm… | 13:32 |
| mntmn | Kooda: why should wlroots need those? | 13:34 |
| Kooda | I don’t know, that’s why it’s weird | 13:38 |
| mntmn | my guess is that it could be about egl _libraries_ and that is something that falls out of the mesa build process, but after install it might need to be registered once by ldconfig | 13:49 |
| mntmn | lastebil: i would recommend to check where ninja install puts the mesa libraries at the end of the mesa build and then ldconfig /that/directory | 13:50 |

| lastebil | there is definately no egl binary on the system after the mesa build pass | 16:08 |
| - amelia_ (QUIT: Quit: Leaving) (~amelia@unaffiliated/amelia/x-6378434) | 16:09 | |
| Kooda | That’s indeed the library then | 16:13 |
| Kooda | Did you build Mesa with the right configuration? | 16:13 |
| lastebil | I built mesa with the script inside of mkuserland2.sh | 16:15 |
| lastebil | that is to say: I have extracted the git command, the patches, meson, and ninja commands into their own script, and run it. | 16:15 |
| lastebil | that is NOT to say that all the libraries / items required for building were there: as this is void, not debian; I am looking for which packages are needed to be installed prior. | 16:16 |
| lastebil | it _builds_ now, but there may be a misisng prerequisite, I have just decided to try installing libglvnd-devel - as that MAY have a file needed (apparently it is part of the build process on fedora) | 16:17 |
| mntmn | wait wait | 16:17 |
| lastebil | not that void is any more like fedora than it is like debian, just that it may contain missing headers. | 16:17 |
| mntmn | lastebil: egl is not a binary. | 16:18 |
| lastebil | right, it's a run-time dependency. it's also missing (: | 16:18 |
| mntmn | lastebil: it's the egl library. something that mesa should provide. | 16:19 |
| lastebil | post-build, there are only 2 places "egl" appears on the filesystem: both within /src directories in the mesa build subdirectory | 16:19 |
| mntmn | egl is just the pkgconfig name, i think the actual libs have a slightly different name | 16:20 |
| mntmn | one moment | 16:20 |
| lastebil | right, like egl.o or egl.a or similar? | 16:20 |
| mntmn | i think more like EGL | 16:20 |
| lastebil | ok let's check for that while it rebuilds | 16:20 |
| mntmn | lastebil: libEGL.so | 16:21 |
| lastebil | hmm, didn't notice this before | 16:21 |
| lastebil | expat: YES | 16:21 |
| lastebil | llvm: NO Subproject directory not found and llvm.wrap file not found | 16:21 |
| lastebil | perhaps that is the issue (: | 16:21 |
| mntmn | lastebil: but your mesa build process completes, right? | 16:21 |
| lastebil | yes. also, those are sitting in both /usr/local/lib and /usr/lib post-mesa-build completion | 16:22 |
| mntmn | lastebil: did you do ldconfig /usr/local/lib ? | 16:22 |
| mntmn | before trying to build wlroots | 16:22 |
| lastebil | I did, and your script is also doing the generic 'ldconfig' before, and I have included that also at the start | 16:22 |
| lastebil | but let's try one more time (: | 16:23 |
| mntmn | lastebil: ok. what is the output of: pkg-config --libs egl | 16:23 |
| mntmn | (for me that's -L/usr/local/lib -lEGL) | 16:23 |
| mntmn | when the meson config process for wlroots chokes with a "egl" dependency error, it means that it called pkg-config --somethingsomething egl and that failed | 16:24 |
| lastebil | now it finds it. hmm. interesting. | 16:24 |
| mntmn | lastebil: maybe /usr/local/lib needs to be added to /etc/ld.so.conf | 16:24 |
| mntmn | very possibly so | 16:25 |
| lastebil | it does hit another issue but I can solve that one I believe. | 16:25 |
| lastebil | yeah I'm betting it does. let's add that. | 16:25 |
| mntmn | i also have /usr/local/lib/dri in /etc/ld.so.conf | 16:25 |
| lastebil | bbiab | 16:25 |
| mntmn | (not 100% sure if required, but in case of further problems...) | 16:25 |
| erlehmann | lastebil, in case you are using shell scripts too, consider redo style (it is a small tool to have dependencies for shell scripts) to rebuild faster | 16:27 |
| + amelia_ (~amelia@unaffiliated/amelia/x-6378434) | 16:33 | |
| erlehmann | mntmn, sorry i do not want to lead you astray, better finish your stuff before you listen to anything i have to say | 16:42 |
| lastebil | yeah planning on doing some changes to them after. (like applying the patches to the local git repo (: ) | 16:59 |
| lastebil | just had a large older TV dropped off so had to go deal with that (: | 17:00 |
| erlehmann | lastebil, is it by any chance a 42" braun tube? | 17:36 |
| lastebil | sadly, no. | 17:40 |
| erlehmann | do you ♥ CRT? | 17:42 |
| lastebil | they are very good for certain things, such as older videogame systems (: | 17:47 |
| lastebil | not sure why, but the ldconfig is ignoring things in /usr/local/lib/ldconfig - and I can't figure out why. even when that directory is explicitly given on the command line, it ignores it. | 17:48 |
| lastebil | I'm hacking through it by putting the files it can't find (such as wlroots) in /usr/lib/ldconfig - but this is something I will need to fix. | 17:49 |
