| oere | Dear all, I followed the steps described at https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel but I was not able to modify it so the generated kernel debs have an append local version extension ... I'm using pdebuild --use-pdebuild-internal and used 'dch --local +test' before building it ... is there any other usable documentation ... the background is to patch the kernel to support Beignet on Haswell (https://01.org/zh/beignet/download | 10:55 |

| arges | infinity: so for bug 1454687, the nx 842 module needs to be loaded in the initramfs to enable usage with zswap. If modules=most doesn't set that in initramfs-tools, is there an 'ubuntu' way to append to that anywhere? | 17:51 |
| ubot5 | bug 1454687 in linux (Ubuntu Vivid) "add NX 842 hw compression patches" [Medium,In progress] https://launchpad.net/bugs/1454687 | 17:51 |
| infinity | arges: Except that we enable zswap after we pivot, not in the initramfs. | 17:53 |
| infinity | arges: This is another case of "bug submitter doesn't use Ubuntu, and assumed we do it the same way as RedHat". | 17:53 |
| arges | infinity: yea. i got that part when I saw dracut | 17:53 |
| arges | : ) | 17:53 |
| infinity | arges: We do have an initramfs zswap hook but, confusingly, we only use it in the installer. And I've been meaning to consolidate it with zram-config. | 17:54 |
| infinity | arges: But if these need to be loaded pre-zswap (but otherwise, not necessarily loaded at all), they belong conditionally in zram-config. | 17:55 |
| arges | infinity: ok | 17:56 |
| infinity | arges: Err, assuming zram and zswap are the same thing. Maybe they're not. | 17:57 |
| arges | infinity: the other thing is the bug commenter said he's working on patch to make it change it requireing to be done at boot time | 17:58 |
| arges | so maybe wait for those patches | 17:58 |
| infinity | arges: Ahh, zswap != zram. How confusing. | 18:00 |
| infinity | arges: Okay, so, maybe the compressors do need to be in the initrd for this, much like lz4 is. | 18:02 |
| infinity | arges: So, I'd grep initramfs-tools for lz4, and add these in the same spot. | 18:02 |
| arges | infinity: ok i'll target that package too | 18:02 |
| infinity | Which, of course, is being pulled in as a dep, so isn't mentioned at all in the source. :P | 18:03 |
| infinity | arges: Anyhow, it'd be the auto_add_modules function. | 18:04 |
| arges | infinity: ok i see it | 18:05 |
| infinity | arges: Don't worry about arch-restricting, it ignores modules that don't exist, IIRC. | 18:06 |
| infinity | arges: Though, easy to test my assertion on an x86 machine. | 18:06 |
| arges | infinity: yup. was going to ask. | 18:07 |
| arges | infinity: does this seem reasonable? http://paste.ubuntu.com/11775115/ | 19:01 |
| infinity | arges: Probably. You'll need to do some testing to make sure that (a) it's needed, and (b) it actually does something. | 19:15 |
| infinity | arges: I, however, might sleep. I've been up since yesterday morning. | 19:16 |
| arges | infinity: ok | 20:08 |
