  1. I don't know how much work it is... but are you able to provide additional all-in-one patches, please? This would really ease the process of testing.

    And: What patch would you recommend at first for me, when I am still glad with VRQ test1 on 4.6.3 (+BFQ +modded TuxOnIce)?

    Thank you in advance and BR,
    Manuel Krause

    1. What I do is check out whole linux-gc repo from bitbucket, then switch branch to needed one say v4.6.3-vrq2, then apply patches + configure kernel, then build the kernel directly in that branch, then git reset & clean, rinse and repeat :)
      In the VRQ branch there is VRQ + BFQ + Graysky's GCC patch, last two are optional for build, so does not interfere if You don't need, if You need, just configure them.
      Hope this helps and if this is all known and not needed for particular situation, then sorry for noise... If I'm doing smth wrong, please correct me.

      Thank you for yor reply. I don't use the "fetch-all" approach at all. I also don't like the related git things. Usually I download the vanilla base kernel source from openSUSE as .rpm and after installing, apply _all_ the patches in question. Aside from the mess of work to download Alfred's commits one by one from within the browser, this allows a closer look on his work & changes.

      @Alfred:
      Thank you for the added all-in-one VRQ2 test3 patch link. This kernel is up and running well for 8h now. Mmmh, you've really switched to the 5ms setting. :-)

      Git is very helpful when you get used to it. Thanks for you sharing here.

      @Manuel
      After compare the performance between 5ms and 6ms, I can't see huge difference, so 5ms is default now.

  2. Hi!

    I compiled test1 patch, with HZ 300 + BFQ and base config taken from Fedora, on my laptop the power consumption was rather high... 4.5.5 VRQ did not have this. Responsiveness was good, thanks.
    I suppose I'll take standard VRQ patch and give it a go.

    thanks, br

      Please test the 4.6 VRQ branch, there is unlikely the new code changes in -test branch cause power consumption regression, but if it happens, I'd try to address it.

      I recompiled test3 again, this time I used config from 4.5.5 VRQ and it seems that power consumption is back to normal levels!
      So no worries, thanks for Your work and quick reply.
