Kernel tests
by Jon Stanley 11 Aug '14

So I have to admit that I saw that Fedora badges were now being awarded for kernel testing, so I went ahead and submitted my results. In the process, I made a few observations (both on the process and on the tests themselves): First from the process standpoint, has it been thought about to make the process easier for testers than going to a webpage and uploading results manually? Could we make it even easier by somehow asking for a FAS identity and then uploading it? As for the test content itself, the test header has no information as to what hardware it is running on, which for performance tests matters, and possibly for some functionality tests as well (vendors with buggy firmware, etc). I'm not sure what format patches are preferred in, but there's a branch hw-info of git://githuib.com/jds2001/kernel-tests that has this. A log header now looks like: Date: Mon Aug 11 16:39:26 EDT 2014 Test set: default Kernel: 3.16.0-1.fc22.x86_64 Release: Fedora release 20 (Heisenbug) Result: PASS Failed Tests: None System Manufaturer: Hewlett-Packard System Product Name: h8-1070t BIOS Version: 7.05 BIOS Release Date: 05/18/2011 Processor: Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz gcc version: gcc-4.8.3-1.fc20.x86_64 glibc version: glibc-2.18-12.fc20.x86_64 Virtualization: none ============================================================ There might be other useful things to include as well, these are some things that I can think of from a "possible to provide in a singe line" output. Note that since some users might be concerned about giving out lots of (potentially sensitive - think things like serial number/asset tag), I didn't include a full dump of dmidecode, though that really would be the holy grail of information that I'd want (and lspci, lsmod, etc). Another test that would be worthwhile that I don't think I'm smart enough to write on my own is whether AutoNUMA is working as intended. This would of course require NUMA hardware (or booting a system with fake NUMA).

3.16.0 building
by Josh Boyer 04 Aug '14

04 Aug '14

Hi All, The final 3.16.0 release is building in koji now for both F21 and rawhide. I'll leave both on this kernel version for most of the week due to Flock. Next week, rawhide will move on to the 3.17 merge window. Fedora 21 may or may not wind up with 3.17 for release. We're going to keep an eye on how that release is shaping up in rawhide and how the development schedules align. As always, if you have questions please let me know. josh
