| garga | Hey! I need to create a custom kernel based on focal hwe-5.13 adding one extra builtin item to support a new hardware and I'm failing to get it done. IS there any documentation with needed steps to get it done? | 11:47 |
|---|---|---|
| garga | I managed to create the new release and build it but I'm getting a "disagrees about version of symbol module_layout" error when I try to load modules. I already updated debian.netgate-5.13/abi/amd64/generic file with new ABI information but error persists | 11:47 |
| xnox | garga: does it have to be built-in? and can you not instead modify initramfs-tools configuration to include and load extra driver? | 12:40 |
| xnox | garga: you can build with skipmodule=true skipabi=true options to skip abi checks, or commit .ignore files to skip those. but this may lead to other problems. | 12:41 |
| xnox | garga: what config option in particular? | 12:41 |
| xnox | garga: if it makes sense to have something built-in, maybe we can fix that? | 12:41 |
| garga | xnox: it's mandatory to be builtin to have console working on new Phantom Lake hardware. This change was accepted on jammy mainline kernel (CONFIG_SERIAL_8250_MID=y) | 12:50 |
| garga | but I need to build a hwe kernel for focal because our product is based on focal yet | 12:50 |
| garga | When hwe-5.15 is released for focal it will already have this change in place an my custom kernel will be discarded | 12:51 |
| xnox | garga: linux-hwe-5.15 is already available for focal, as an edge kernel. You can already install it with `sudo apt install linux-generic-hwe-20.04-edge` | 13:03 |
| xnox | why not do that? and switch to `linux-generic-hwe-20.04` once v5.15 is rolled to standard flavour. | 13:03 |
| garga | xnox: the version available on focal still don't have that change | 13:57 |

| xnox | sadness and despair | 14:50 |
| garga | xnox: I found my mistake here and managed to build a kernel that works | 17:27 |
| garga | Now I just need to figure out how to build a initrd with casper bits in order to build a custom ISO with this kernel | 17:27 |
| garga | any hints would be much appreciated | 17:27 |
| Courtland | Anyone have thoughts on this kernel bug in 22.04 LTS? Since it was fixed in mainline 5.15.36, I am trying to understand if it "should" already be fixed in `5.15.0-39` or if not, when to expect it to appear in any of the jammy master-* branches. Sorry if this is a stupid question, I'm still learning about the ubuntu kernel maintenance process. | 19:11 |
