zygaogasawara: hey! :)14:17
zygaogasawara: I have an idea I wanted to ask you about14:17
zygaogasawara: so someone showed me the snapcraft tree for the core kernel snaps: https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux-snap/+git/xenial/tree/snapcraft.yaml?h=pc14:17
zygaogasawara: and since we recently moved gadget snaps to github (through a launchpad mirror and auto-build pipeline) to github.com/snapcore/snapd I was wondering if we could to the same to the kernel snap so that people can find the snap definition more easily and it's all under one hood14:18
ogasawarazyga: let me chat up bjf and team about it14:19
zygaogasawara: thanks!14:20
zygaogasawara: I wrote a small blog post about what's happened to gadget snaps http://www.zygoon.pl/2016/12/ubuntu-core-gadget-snaps.html -- there are plenty of links from that post to repositories both on github and launchpad14:21
ogasawarazyga: ack, thanks.14:21
* ogasawara will go read14:21
hallynanyone have a absolute-minimal-working kernel config sitting around for bisect purposes?16:16
smbhallyn, the mainline builds do come with config patches (http://kernel.ubuntu.com/~kernel-ppa/mainline/). Would those work for you? (down the page in a certain version directory)16:53
hallynsmb: maybe - my guess would be those are for full fledged kernels :)  i just want quick builds, don't need most filesystems etc.16:57
hallyn(just enough to boot)16:58
hallyni'll just make my own again - thx16:58
smbhallyn, ok. sorry would not have any minimal configs aywhere17:06
hallynmake localmodconfig is new to me18:00

hallynanyone still using ccache these days for kernel builds?  20:23
rtghallyn, I found that ccache took longer, at least on the servers that I build on20:31
rtgtoo many files and an inefficient hash algorithm methinks20:31
hallynhm, makes sense20:32
hallyn(haven't used it in like 10 years)20:32
hallynthanks20:32
keeswhat is "linux-hwe-edge" ?21:18
keeslooks like for "latest supported kernel on Xenial" I should install linux-image-generic-hwe-16.04-edge linux-headers-generic-hwe-16.04-edge ?21:21
rtgkees, there is an email about it on the ubuntu-announce list21:32
keesrtg: ah, thanks!21:33
rtgsubject "16.04.2 - Rolling HWE Kernel"21:33
keesLooks like https://lists.ubuntu.com/archives/ubuntu-announce/2016-November/000215.html21:34
rtgyup21:34
keesoh, and remember our chat about intel iommu? finally tested on a non-modern machine and any graphics access broke the system. "intel_iommu=on,igfx_off" seems to fix it, though. I still don't think it's sane enough for even that to be the default, based on things like the audio stack failure bug reports. :(21:36
rtgkees, I'll leave it off then for sure.21:37
keesyeah :(21:38
keesin related news, I need to send a quirk for my chipset so I won't need the igfx_off in the future. ;)21:38
rtggood luck21:39
keeshehe21:39
* rtg has to run21:39
keescya21:39
hallynhm, why do all of the 3.x kernels, when built with make deb-pkg, hang at loading initrd?22:48
hallyn(on a xenial host)22:49
hallynsome systemd thing?  maybe i should install upstart?22:49
hallynguess i'll try upstart22:50
