| hggdh | phillw: this is, indeed, the current kernel for yakkety. Why the version string, though, I do not know | 00:08 |
|---|---|---|
| phillw | hggdh: thank you, sir. I'll *carry on testing* :) | 00:09 |
| hggdh | :-) | 00:10 |

| bjf | phillw, from the changelog the odd abi number is to avoid namespace clash with xenial kernels while yakkety ist still a 4.4 kernel (which hopefully isn't for much longer) | 02:52 |
| phillw | bjf: thankyou for the clarification :) | 09:19 |
| xnox | phillw, hggdh: the version string is correct. | 09:33 |
| xnox | all other kernels in 4.4 series were built for xenial and copied into yakkety. | 09:33 |
| xnox | this one was built in yakkety with sources different from xenial. | 09:33 |
| xnox | hence the probably-will-never-class-with-xenial version number. | 09:34 |
| xnox | in theory this would not be required at all, as by now, one usually has a new kernel series in the development release - e.g. v4.6/v4.7/v4.8 but we are not there yet. | 09:34 |
| xnox | phillw, also see #ubuntu-release backlog from last week. | 09:34 |
| phillw | xnox: I'm on the mailing lists, but missed this one.. Would it be possible to put out a mail to clarify for any others who are testing and scratching their heads? :) | 09:35 |
| xnox | phillw, #ubuntu-release is IRC channel. | 09:36 |
| xnox | phillw, there is nothing to clarify and nobody is scratching their heads =) | 09:36 |
| phillw | xnox: okies, just me being dumb, in that case :) | 09:36 |
| xnox | version strings really do not matter at all, and encode ABI | 09:36 |
| xnox | phillw, to be honest we could be using ephemeral key hash in the package names, to encode the ABI. | 09:37 |
| xnox | just to make sure the abi tag is meaningless fingerprint like string. | 09:37 |
| phillw | that is something else you've just taught me! I was under the false impression that grub always chose the highest number for the default kernel :) | 09:37 |
| xnox | nope. | 09:38 |
| xnox | it picks last configured kernel. | 09:38 |
| xnox | ubuntu -> vmlinuz -> symlink to last kernel image that dpkg postinst was called on. | 09:38 |
| xnox | that has always been the case. | 09:38 |
| phillw | thanks, I'll leave you good people in peace!! On the plus side, if I do get asked I can reply... saves another person landing here asking!!! | 09:41 |

| xnox | Your kernel's Performance Events Subsystem does not support your processor type. | 13:30 |
| xnox | horum, but ibm say it should be.... | 13:30 |
| chrisccoulson | does the kernel in yakkety support MADV_FREE? | 13:31 |
| apw | chrisccoulson, that is documented as 4.5+ so we will, and currently don't | 13:33 |
| chrisccoulson | apw, ah thanks. See bug 1613258 for context - the new glibc defines MADV_FREE | 13:34 |
| ubot5 | bug 1613258 in glibc (Ubuntu) "signal 4 ILL_ILLOPN in webbrowser-app tests (glibc upgrade?)" [Critical,Triaged] https://launchpad.net/bugs/1613258 | 13:34 |
| apw | chrisccoulson, that may have been built with the 4.6 which was in -proposed for a time (glibc) | 13:35 |
| apw | that said, i am supprised that glibc is assuming it can use it | 13:35 |
| apw | infinity, ^ | 13:35 |
| apw | chrisccoulson, oh but it is likely the seccomp bits right? so just a profile change ? | 13:39 |
| apw | chrisccoulson, in the sense it is resonable for glibc to define it, and the kernel to return EINVAL or indeed work, but we need the seccomp profile to reflect that possibility | 13:41 |
| chrisccoulson | apw, we'll probably end up doing the same as http://code.qt.io/cgit/qt/qtwebengine-chromium.git/commit/?h=49-based&id=b12ffcd411d4776f7120ccecb3be34344d930d2b | 13:43 |
| apw | chrisccoulson, wouldn't it make more sense to try MADV_FREE and if it fails ENOSUPPORT or whatever dropback to whatever it does when it doesn't have _FREE ? | 13:45 |
| apw | so one uses it in 4.5 and not before that all shiney and automatically | 13:45 |
| chrisccoulson | apw, we could probably do that | 13:45 |
| apw | i assume it uses like _DONTNEED or similar instead | 13:46 |
