building and using yocto 1.1
|
Xianghua Xiao <xiaoxianghua@...>
when I built 1.0 out of the box, it took 7 hours.
on the same machine/network, yocto 1.1 took a full 12 hours, not sure what happened to cause this nearly doubled build time. after the default build(bitbake core-image-sato), I run 'runqemu qemux86', click on 'tasks', try to add a new task, however my input is shown non-english, or garbage on screen, which I have seen the same issue on yocto1.0 release as well. this is a 10.04 ubuntu 64bit machine. don't know what to say about it, just my OOB(out-of-box) experience xianghua |

What machine are you using (amount of ram, disk space, and cpu cores)?

What configuration did you set for parallel builds? I can build 1.1 on an 8 core i7 system w/ 8 GB of ram, set with parallel settings of 8 thread and 8 parallel make jobs, in about 100 minutes (or less). --Mark On 10/28/11 9:20 AM, Xianghua Xiao wrote:

Xu, Jiajun <jiajun.xu@...>
We also test 1.1 on a 4-core Core i7 machine with 4GB memory. The build time is about 120 minutes. The detailed test result and configuration is on https://wiki.yoctoproject.org/wiki/Performance_Test. Maybe you could follow the page and retry the build.

1 thread 1 parallel due to past experience I had from the past(parallel make did not work well reliably) thanks, xianghua On Fri, Oct 28, 2011 at 9:45 AM, Mark Hatle <mark.hatle@...> wrote:

sorry for the typo in my previous email.

guess I need get a i7 and start to use parallel build again. is there a way that, when a release is made, all the related source tarballs can be download as a whole? the separate download slows build a lot for the out-of-box test as well. thanks, xianghua On Fri, Oct 28, 2011 at 11:13 AM, Xianghua Xiao <xiaoxianghua@...> wrote:

Enable parallel builds and your performance will be significantly better. If you have hyperthreading enabled, and setup a 4/4 parallel build. I would expect about a 4-5 hour build time. (May be faster) --Mark thanks, |

1.1 is 12 hours while 1.0 was 8 hours, using the same machine on the same network, not sure why. input under sato does not work, it's showing some non-English letters while i type. xianghua On Fri, Oct 28, 2011 at 11:23 AM, Mark Hatle <mark.hatle@...> wrote:

I do want to point out that:The build time issue is known, we're doing more work (building more things) in 1.1 - however, reducing build time is a primary goal and I expect there to be a reduction in build time by the time 1.2 is released. Could you file a bug for your input issue? That way it's more likely that someone with the appropriate skill set will be made aware of it. http://bugzilla.yoctoproject.org Thanks, Joshua -- Joshua Lock Yocto Project "Johannes factotum" Intel Open Source Technology Centre |
