minutejosch: yes, if there was output it would be much better @ usability00:18
minuteartfwo: sweet!00:19
joschminute: packages are allowed to put configuration into /etc/dkms/framework.conf.d/*.conf in case you'd like to have verbose=1 shipped by reform-tools00:20
minutejosch: nice00:45
minutebtw i tested the qcacld package auto update post install script method locally on my laptop (just out of curiosity), and it works. but the script file needs to be executable.00:47
minutefor testing i logged the output to a file, it repeats 3 times "Waiting for cache lock: Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 27555 (apt)..." and then starts installing00:48
joschgood to know!00:49
joschi think for debian stable (on reform.d.n) i'll go the ezurio-qcacld-2.0-dkms route as that will allow installing the dkms modules for arbitrary kernels (stable, stable backports, ...) and not just the kernels for which mntre.com built the binaries00:52
minutejosch: btw i'm sorry that somehow i didn't understand you were so disappointed with this solution (.ko in a .deb). i wish it had occured to me that this might have been solvable with the dkms binary mechanism back then, but i really have a hard time understanding the dkms documentation00:52
minutejosch: yes, i think that's fine00:52
minutewhen i was looking for dkms on the web and found the Dell repo a few hours ago, i thought this must be some different DKMS project00:53
minutebut it is actually a dell project00:53
joschyup00:53
joschi wish i were more of a dkms expert, then i could actually be more constructive rather than saying why things might not work XD00:53
minutei guess there are not super many packages using dkms (which is a good thing)00:54
joschthat and that it's just a big bash project00:56
joschthe dkms files are essentially bash scripts that get sourced00:56
joschand docs are lacking00:56
josch(as you also experienced)00:57
joschit took me reading the dkms source to figure out that i had to use BUILD_EXCLUSIVE_ARCH="^(aarch64|x86_64|riscv64)$" to limit qcacld to 64bit architectures00:57
minuteoof00:58
joschnowhere does it say that this is a regex00:58
joschor what kind of architecture names those are (it's the uname -m output)00:58

minutejosch: thanks for taking care of it! i can test it today and record the time ^^10:48
joschon the Debian CI systems, building it takes 3:40 minutes but those are *very* fast machines and even with as little as 3 minutes i'd like at least some progress indicator to know that the system doesn't hang but is still doing something10:50

minutejosch: btw one of the worst things in terms of UX is update-initramfs12:56
minutealways takes a very long time and doesn't output any progress, and outputs an error about zsts12:56
joschyes, i wish that one had quite a bit more verbosity as well12:58
joschand the zstd warning is super confusing12:58
minuteyeah :/12:58
minutealso i have doubts that the performance is optimal12:58
joschyou called it an error (which it is not) but most people i talked to (yes, this is so annoying that this is a conversation topic) also interpret it as an error12:59
minuteyeah12:59
minutebtw the postinst hook i made last night works, i reran the build_qcacld and reprepro steps of the last pipeline of reform-debian-packages and the auto-install on kernel upgrade works on device13:00
josch\o/13:00
minutethere are of course edge cases, i.e. if you went offline exactly after the upgrade, it wouldn't work13:01
joschi should've taked to ben last week about update-initramfs XD13:04
josch*talked13:04
minuteohh yeah :D13:05
minuteneed to benchmark what is so slow there... maybe the compression?13:07
minutewe already installed around 140 more devices with the older version of system image and qcacld2 package... updating the packages would take a long time due to update-initramfs13:13
minuteso we should probably put a note in the box that people should run apt update && apt upgrade after connecting to the network13:13
minutewe could also put that in the next CS update post13:13
joschi have good news and bad news13:15
joschgood news: it's not the compression that makes mkinitramfs slow13:15
joschbad news: it's tons and tons of lines of shell and modinfo calls13:16
joschminute: this is how verbose update-initramfs output would look like: https://termbin.com/qdw913:22

minutejosch: that looks better than being quiet though13:24
minutejosch: is it adding those files one-by-one or collecting them into a list and then adding them at-once? somehow it is really hard for me to imagine that making an archive/fs image that is only 10s of MB should take this long on a modern computer13:25

joschminute: in case the mkinitramfs situation interests you, i have dug a bit into it19:06
joschof the 40 seconds that it takes over here on a311d, only 5 seconds are spent on the actual zstd compression19:06
joschanother 4 seconds are spent on running the hooks19:07
joschbut all of the rest is just slow because a) shell and b) 824 calls to modinfo -k, 465 calls to cp and 174 calls to mkdir19:07
joschfixing this would likely be a rewrite19:08
Twodisbetteryo yo yo, what up folks? Have any of you heard of Bluefin OS? Had a chance to take it for a spin? I wonder if something like that could one day be considered on the Reform? I ask because imutable nature of the OS is great, in that things just don't break anything in updates either. I'm trying it on the Framework 13 now, but just wondering if anyone here has kicked the tires with it?19:25

minutejosch: sounds like an interesting candidate for rewriting in a faster language20:09
minutejosch: also those modinfo calls sound expensive20:10
joschthe modinfo calls are for figuring out which kernel module requires firmware20:10

reform3633Hi, i delete the partitions of the emmc and now i try restore. the pocket has been booted by sd ... hope its okay to ask here20:35
erlealso, shell scripts aren't necessarily slow, but invoking subshells is, definitely. every pipe and $([…]) or `[…]` might be a speed bump.20:39

erlejosch i have identified a few places where the hook-functions can be made marginally faster already with the same functionailty (like preventing path lookups and using case instead of if because it is faster), but without stracing the thing i would not know if that has an actual impact – because it has a LOT of subshell invocations.23:27
erlei am not going to do that right now – but if you want to refactor those functions, i'd be glad to assist. it's certainly possible to make this faster, i just don't know how much.23:29
