| dannf | rtg: we have people wanting to play with xgene/utopic - mainly our linaro folks wanting to test out new arm64/kernel features - problem is they don't have luxuries like nic drivers, reboot support (still iterating in review upstream). question is, are you ok w/ carrying temporary versions of these drivers that we trade out w/ accepted versions later, or should i maintain a tree/ppa for them? | 14:33 |
|---|---|---|
| dannf | and is the answer different now vs. when we're nearing freeze? | 14:34 |
| rtg | dannf, you're talking about utopic ? | 14:34 |
| dannf | rtg: yes | 14:34 |
| rtg | dannf, you've got a few weeks yet that I can be flexible. As we get closer to freeze I'll clamp down on changes. | 14:35 |
| dannf | rtg: flexible meaning willing to take not-yet-upstream stuff, and clamp-down meaning no-more-swaps? | 14:36 |
| rtg | dannf, yup | 14:36 |
| dannf | rtg: ack | 14:37 |
| rtg | dannf, so, around Oct 1 I'll start to get more conservative. that said, the arm64 APM patches are quite testable. | 14:37 |
| dannf | rtg: do you know when you'll move to a 3.16-rc? after rc1? | 14:39 |
| rtg | dannf, it kindof depends on how stable it is. usually I'm not too comfortable inflicting a new kernel release on the real world until -rc2 or 3 | 14:39 |
| rtg | -rc2 at the earliest for sure | 14:40 |
| dannf | ok. then we may ask for a few more cherry-picks for 3.15 in the meantime if that's ok. i'm also not sure what the best way to ask on-list for a cherry-pick is - if its a clean cherry-pick, do i need to attach patches, etc? | 14:40 |
| rtg | dannf, if they are clean then just the list of commits is fine. a pull request is best. | 14:41 |
| rtg | a pull request is _easiest_ for me to consume, regardless if they are clean cherry picks, etc. | 14:42 |
| dannf | rtg: ok | 14:42 |
| dannf | wfm | 14:42 |
| rtg | smb, could you check to see if Utopic still needs aabdb7729a2da806e60bf2d956f126e2cc3a0d85 (UBUNTU: SAUCE: kvm: Force preempt folding in kvm on i386) from Trusty ? | 17:02 |
| smb | rtg, I can. Gut feeling would be no, as there was a better but more invasive changeset mentioned, leading to the smal stable request | 17:04 |
| rtg | smb, cool, I'll ignore it for now | 17:04 |
| smb | Just have to figure out when those changes were in. ok, yeah | 17:05 |
| smb | rtg, ok, you can continue to ignore it for utopic as the four patches are in there. Only 3.13 and 3.14 were needing the other patch | 17:08 |
| rtg | smb, ack | 17:09 |
| rtg | dannf, does Utopic still need 'UBUNTU: [Config] CONFIG_TRANSPARENT_HUGEPAGE=n for arm64' ? | 17:44 |
| dannf | rtg: TBD. that's on my list to verify | 17:55 |
| dannf | the patches i was monitoring that were supposed to fix it never landed, but i saw another bug fix go in that might be the real problem | 17:56 |
| rtg | dannf, then I'll leave it out until further notice. just remember it if things get weird. | 17:56 |
| dannf | yep, will do. | 17:56 |

| dmsmr_ | I'm working on a kernel module and it triggers a BUG() as follows | 21:07 |
| dmsmr_ | [ 1077.052029] kernel BUG at /build/buildd/linux-3.13.0/include/linux/scatterlist.h:65! | 21:07 |
| dmsmr_ | How can I find out the code that triggers it? | 21:07 |
| dmsmr_ | I've downloaded the kernel source but want to be sure about the line. | 21:08 |
| dmsmr_ | Also, how can I find out my current kernel .config? | 21:09 |
| dmsmr_ | Okay, config is under /boot | 21:10 |
