| gnarface | so, i tried to build a kernel for my pine64+ board and it just boot loops after "starting kernel..." | 16:45 |
|---|---|---|
| gnarface | the last one worked fine and as far as i can tell the only thing i did different was i used the current kernel source package and i built it on the bare metal instead of cross-building | 16:46 |
| gnarface | any ideas? | 16:46 |
| gnarface | i'm sure it's something dumb i'm forgetting but there it is | 16:46 |
| gnarface | hmmm... it's smaller than the previous kernel, not by much, but enough to be sure that's not the problem... | 17:02 |
| gnarface | i didn't upgrade u-boot, but i'm only going from kernel 5.18 to 6.1 so i didn't think that would matter | 17:18 |
| gnarface | ugh, nevermind, mabye found it... | 17:28 |
| Hurgotron | do tell | 17:30 |
| gnarface | could have sworn i marked the root filesystem as "*" not "M" but it's clearly "M" | 17:32 |
| gnarface | re-testing is gonna take some time though, these things don't exactly build a kernel fast... | 17:32 |
| gnarface | there's every possibility i missed something else important, if i missed that | 17:33 |
| gnarface | i guess we'll see | 17:33 |
| Hurgotron | :) | 17:36 |
| gnarface | Hurgotron: got any opinions on whether i should use -O2 or -Os on hardware like this? | 17:39 |
| gnarface | some have suggested that due to hardware limitations, -Os might actually run faster, but i'm not clear on real numbers | 17:39 |
| agneli | gnarface: for the -O I believe you need to check every and each aplication separately | 18:44 |
| agneli | your milleage might vary ;) | 18:45 |
| gnarface | i see | 18:55 |
| agneli | you might as well get code that is slower | 18:56 |
| agneli | and if you give sufficiently big -O your code might not actually do what it is supposed to do :) | 18:56 |
| agneli | probably a good topic to discuss on #gentoo-chat channell ;) | 18:57 |
| agneli | or whatever it is called | 18:57 |
| agneli | are you maybe fluent in gdb, please? | 18:57 |
| gnarface | no, i am not, unfortunately | 19:07 |
| gnarface | though i doubt i'd be trying something crazy like -O3 ever again anyway | 19:07 |
| gnarface | good idea on the gentoo chat though... | 19:07 |
