[opensuse-virtual] does xenpm work for opensuse kernel-xen?
hi, i'm trying to get Xen cpu scaling & power management (either =xen _or_ =dom0-kernel), to no avail. @ kenel-default, cpufreq et al. works fine. @ kernel-xen, however, i've filed a bug (https://bugzilla.novell.com/show_bug.cgi?id=527800) with details included ... digging around, however, it seems that it 'worksforsome' w/ other configs & other distros -- and leaves me wondering if the problem is local or systemic :-/ can _anyone_ here report success with enabling xenpm under openSUSE's kernel-xen? thanks! -- To unsubscribe, e-mail: opensuse-virtual+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-virtual+help@opensuse.org
I have not done anything with xenpm. However, I know that Intel did pretty extensive testing of the xen power management features for SLES 11 (at least where their hardware was concerned). Have you tried this same stuff on SLES 11 XEN? It is newer and better tested than openSUSE 11.1 XEN. Sorry I can't provide more info. Jason

SLES 11 Xen is *newer* that openSUSE 11.1 Xen? (stunned silence! digging furiously ... ) Xen version in current SLES 11 is ... ? -- To unsubscribe, e-mail: opensuse-virtual+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-virtual+help@opensuse.org

(stunned silence! digging furiously ... )
Xen version in current SLES 11 is ... ?
They are both technically XEN 3.3.1, but SLES 11 is based on a newer changeset, and had about 2 months of additional hardening and testing. Plus all of the hardware partners tested only SLES XEN, and most of their fixes went in during the last two months of SLES development, so they missed openSUSE 11.1. BTW, for XEN, the SLES version is always newer than the previous openSUSE version. The only exception to this is the fact that they didn't allow us to upgrade xen in SLES 10 SP3 because they wanted people to move to the SLES 11 code base. Here's the timeline as an example: SUSE Linux 10.1 XEN 3.0.1 SLES 10 XEN 3.0.2 openSUSE 10.2 XEN 3.0.3 SLES 10 SP1 XEN 3.0.4 openSUSE 10.3 XEN 3.1.0 SLES 10 SP2 XEN 3.2.0 openSUSE 11.0 XEN 3.2.1 openSUSE 11.1 XEN 3.3.1 (changeset 18494_03) SLES 11 XEN 3.3.1 (changeset 18546_12) SLES 10 SP3 XEN 3.2.3 (anomaly) openSUSE 11.2 XEN 3.4.0 or 3.4.1 SLES 11 SP1 XEN 3.4.2 or 3.5 (likely) Also, as I mentioned before, SLES is always better tested than the openSUSE releases. Really only a minimum amount of testing gets done for most of the openSUSE releases, so the quality is an unknown. It's unfortunate that more time isn't spent on openSUSE, but that's the reality of things from a XEN perspective at least.

SLES 11 XEN 3.3.1 (changeset 18546_12)
that's the info i needed. now to figure out if that ^^^ is new enough to address/fix this: https://bugzilla.novell.com/show_bug.cgi?id=527800 thanks! -- To unsubscribe, e-mail: opensuse-virtual+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-virtual+help@opensuse.org
