Boostisbetter | well we are on wake number 21 on the Reform using the 5.12 kernel. | 14:18 |

eery | So I've been thinking about hibernation support on linux -- how has this been supported in the past? It seems like whatever hibernates from userland also has to modify the kernel cmdline each time, then change it back upon resume | 15:03 |
Boostisbetter | Yeah I don't really understand why Linux as a whole has kind of forgotten about hibernation, and they don't really seem to give it much attention, but it works and is a great tool. | 15:08 |
minute | eery: do you really need to change the cmdline back? | 15:13 |
eery | wouldn't you have to remove it to prevent the kernel from trying to resume again? It's not clear from the kernel's documentation | 15:15 |
eery | it kind of makes it sound like you're supposed to change it every time you trigger hibernation | 15:16 |
eery | Boostisbetter: probably because of how it's implemented, it looks ... treacherous when you use an initrd | 15:22 |
eery | if you accidentally touch the filesystem before resuming, bad things happen lol | 15:23 |
Boostisbetter | Systemd 4 life yo. | 15:32 |
Boostisbetter | Haha just kidding. | 15:32 |
eery | not actually relevant here, since systemd is loaded after the initrd does its thing | 15:33 |
eery | I'm always amused at how configurable linux is -- the fact you can disable support for unix domain sockets is pretty crazy, for instance | 15:43 |
eery | makes me wonder how small you could make a toy kernel | 15:44 |

+ bkeys (~Thunderbi@205.185.110.104) | 17:13 | |
minute | eery: i thought that as it is a swapfile, it would just not resume if it doesn't have some hibernation info in it, but ignore it (?) | 17:17 |
eery | It might -- I'll test it later, I'm curious | 17:18 |
eery | gotta make full backups first though :P | 17:18 |
bkeys | minute: How is the prototype cm4 adapter working? I saw it on mastodon | 17:23 |
minute | bkeys: i'm just finishing the layout of rev3! | 17:23 |
bkeys | Any loose estimate of when it will be available for preorder? | 17:24 |
bkeys | I saw you had the banana pi, does the soquarts or raspberry pi work? | 17:30 |
minute | bkeys: it worked pretty well with bpi cm4! just waiting for a patch from neil armstrong | 17:32 |
minute | bkeys: rpi works, too, soquartz was too boring for me to investigate further | 17:32 |
bkeys | What about the Raxda SoM? | 17:32 |
minute | bkeys: it does not exist | 17:33 |
minute | (you probably mean the cm5?) | 17:33 |
minute | but i will start with t-firefly rk3588 adapter also today | 17:33 |
bkeys | https://www.okdo.com/p/okdo-rock-3-compute-module-cm3-4gb-32gb-with-wifi-bluetooth/ | 17:33 |
bkeys | t-firefly rk3588 will be OP | 17:33 |
minute | rk3566... not very interesting i think | 17:34 |
minute | the a311d in bpi is much more powerful | 17:34 |
minute | (hexacore, 4 of which are a73) | 17:34 |
bkeys | Yeah having good CPU isn't as nice when there isn't RAM to back it up | 17:34 |
bkeys | On the current imx8 in this Reform I'm swapping all the time | 17:35 |
minute | well, for my personal usecases it's good for now | 17:35 |
minute | you running gnome? | 17:35 |
bkeys | No, KDE | 17:36 |
bkeys | But Eclipse is also my programming environment of choice and it's RAM hungry too | 17:36 |
minute | ah well, understandable | 17:39 |
minute | how well does kde work atm on reform? | 17:39 |
bkeys | It works just fine, I usually don't have any performance issues unless I have a memory issue | 17:40 |
bkeys | A graphical display manager would be nice to have. Are you able to boot mainline kernels on cm4? | 17:42 |
bkeys | Fedora is my distro of choice and it has official support for the cm4 now; so I'd love to have that | 17:42 |
minute | yes, there is only little customization necessary, like an overlay for audio and rtc, and toggling usb hub reset | 17:58 |
minute | haha i started rcm4 originally in 2021-11-22 | 18:16 |
minute | very slow moving project | 18:16 |
bkeys | minute: What requires little customization? | 18:24 |
minute | running cm4 in reform | 18:26 |
minute | vs the stock pi image, you would need to load an overlay for the above mentioned things | 18:27 |
minute | device tree overlay | 18:27 |
Boostisbetter | minute: so with the cm4 you can run piOS? | 18:28 |
minute | isn't it armbian nowadays? not sure | 18:32 |
minute | one could run any OS supported by the rpi 4 | 18:32 |
Boostisbetter | that's cool. I would run Ubuntu I think | 18:56 |

minute | if this worked i would totally switch to that chip in my personal reform for a while | 22:45 |
bluerise | minute: that's already pretty awesome | 22:56 |
minute | without colorbars there's just flicker though... so something off with the mipi frames | 22:56 |
