apwNotreDev (N,BFTL), well the config change sounds fine, but if you are on anything recent using -lowlatency makes much more sense07:51

marvin24AFAIK, CMA is only a problem on x86(_64), while for e.g. ARM may require it09:30

apwmarvin24, indeed thanks11:03

bjfzyga, is the cert. testing of precise SRU kernels going to get finished up today?15:26
zygabjf: hey15:28
zygabjf: I wanted to talk to you about that15:28
zygabjf: we got tests done but some results are concerning15:28
zygabjf: I'm waiting for the taipei team to get back to the office and run some fwts tests15:28
zygabjf: to see if that was a fluke or is it a regression 15:29
zygabjf: I'll keep you updated as this happens15:29
bjfzyga, ok, thanks15:29
cmaginai submitted a couple pull requests for trusty sru, but it appears there are some issues with gmail. the requests are in the kernel-team archive however: https://lists.ubuntu.com/archives/kernel-team/2014-August/048025.html and https://lists.ubuntu.com/archives/kernel-team/2014-August/048026.html15:30
bjfcmagina, ack15:32
cmaginabjf: thanks15:39
datahi, i am trying to rebuild this kernel: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.16.1-utopic/ Where to I find the ubuntu sources for this? I need to enable the openvswitch plugin in the kernel, as I need both 3.16.1 and openvswitch16:00
bjfrtg, i've reviewed the patches that cmagina mentions above ^ and they look good to me16:28
cmaginabjf: much thanks16:29
=== DarkPlayer_ is now known as DarkPlayer
argesdata: the sources are just the mainline stable v3.16.1 sources plus a few patches for the debian packaging which are in that directory. openvswitch is already present in the 3.16 kernel, what do you mean by enable?16:50
dataarges: I mean compile the module. Doesn't seem to be the case in the standard ubuntu kernel16:59
argesdata: ok, openvswitch is in the mainline/ubuntu kernels. which version of the openvswitch module are you trying to use/compile?17:04
=== Mikee_C is now known as Mikee_C_afk
dataWell, we are sharing our machines for experiments. Previously, we just used the openvswitch-datapath-dkms package. I even recreated it with the new 2.3.0 release of openvswitch, but that doesn't support anythign above 3.14. Problem now is that our colleague needs 3.16, so I figured we could use the in-kernel-version of openvswitch instead of the out-of-tree version17:09
argesdata: ok on my utopic/3.16 and trusty/3.13 machines I just typed 'sudo modprobe openvswitch', and the module seems to be loaded just fine.17:11
apwdata, as arges says you should be able to start from linus/stable commit indicated in the COMMIT file in that directory, apply the 3 patches also in that directory, and have what we used to build the binaries in that directory17:14
apwdata, though our default kernels in the distro also have that enabled17:14
datahmm, if it is enabled, something else may be wrong17:16
datalet me17:16
datacheck17:16
datasorry for the confusion... My colleague apparently installed a kernel build by hand (after I had updated it to the ubuntu version) and added a custom entry to grub. As this is a remote machine, I didn't notice it was booting the wrong kernel. So all is well. Your help was much appreciated.17:17
argesdata: no problem! good luck17:19
databut good to know that it's just the few patches in that directory. Might come in handy at another time.17:19

JoeIsenberganyone here have experience with Ubuntu guests on HyperV? I'm looking for the userland daemon for the key-value transfer for the trusty kernel backported to 12.0420:03
JoeIsenbergin precise it was in the linux-tools package. They moved it to the linux-cloud-tools package but that isn't available for precise20:04
JoeIsenbergI have the source in the kernel code, but I can't seem to build that20:06
