Date: Fri, 16 Mar 2007 17:58:17 -0400 From: Veronique & Vincent <vinctre@...eotron.ca> To: linux-kernel@...r.kernel.org Subject: Fwd: Backport RSDL v0.31: Updated RSDL 0.31 backport for 2.6.18.8 & Debian etch x86_64 RSDL 0.31 kernels availability Hi all, Here is are the backported RSDL scheduler for a 2.6.18.8 kernel and now also for 2.6.19.7 kernel. This release includes the original backported 2.6.20.x RSDL 0.31 patch and also has few cleanups to remove unecessary debian make-kpkg files. This update also includes a small patch to both 2.6.18 and 2.6.19 kernels (http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.20.y.git;a=commit;h=d499ac7a3681e270074e880879d0e0a5ad0849fa). Would a new stable release of 2.6.18 and .19 including that patch be worth it? The provided kernels (only for Debian Etch x86_64) might be usefull to make load comparisons between Vanilla vs CK's RSDL scheduler. Althoug I've been able to backport properly RSDL to a 2.6.18 kernel I'm currently having a bug in the 2.6.19 backported patch. Help finding that bug would really be appreciated. 2.6.19 BUG in action picture available at http://linux-dev.qc.ec.gc.ca/kernel/debian/etch/x86_64/2.6.19/bug-2.6.19-rsdl-031.jpg Official CK RSDL patches available at: http://ck.kolivas.org/patches/staircase-deadline/ Latest CK RSDL 0.31 announcement: http://lkml.org/lkml/2007/3/16/173 Again, nice work CK! --------------------------------------------------------------------------------------------------------------------- 2.6.18.8 backport RSDL 0.31 patch (contains already Ingo's SMT scheduler fix): PATCH: http://linux-dev.qc.ec.gc.ca/kernel/rsdl/2.6.18.8-rsdl-0.31.patch CONFIG: http://linux-dev.qc.ec.gc.ca/kernel/debian/etch/x86_64/2.6.18/CONFIG-2.6.18-003 Notes: Didn't encountered any problems yet. 2.6.19.7 backport RSDL 0.31 patch (contains already Ingo's SMT scheduler fix): PATCH: http://linux-dev.qc.ec.gc.ca/kernel/rsdl/2.6.19.7-rsdl-0.31.patch CONFIG: http://linux-dev.qc.ec.gc.ca/kernel/debian/etch/x86_64/2.6.19/CONFIG-2.6.19-001 Notes: There is currently a bug in the backported 2.6.19 RSDL 0.31 kernel. I've attached a picture of the kernel BUG: call. Help to trace this bug would really be appreciated since I'm not that much a kernel hacker yet! Also note that libata PATA is not enabled and that GFS + DLM is enabled. 2.6.20.3 uses the official RSDL 0.31 from CK: CONFIG: http://linux-dev.qc.ec.gc.ca/kernel/debian/etch/x86_64/2.6.20/CONFIG-2.6.20-001 Notes: Uses the official RSDL 0.31 patch from CK. Libata PATA not enabled, GFS + DLM enabled, KVM enabled.
