What is the best way to pin VCPUs. It looks like the implementation of affinity currently is at best only "soft". Regards, K. Y _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Btw., another question that made me wonder already when doing the original patch: why is it that x86-64 properly uses locking for mm_pin_all(), yet i386 doesn''t need to?

HI, Is it possible to specify CONFIG_PREEMPT_RT=y in the Dom0 kernel? It seems that it is forbidden as it is not a menu option in make menuconfig and gets removed if I manually add it to the .config. I want to run a sound server on Dom0 and am having problems with xruns at present, so need to be able to run a preemptive kernel. Thanks, Chris _______________________________________________

Hi, I would like to know about which threads will be preempted by which on my OpenSolaris machine. Therefore, I ran a multithreaded program "myprogram" with 32 threads on my 24-core Solaris machine. I make sure that each thread of my program has same priority (priority zero), so that we can reduce priority inversions (saving preemptions -- system overhead). However, I ran the following

1: correct LDT checks 2: add address validity check to guest_map_l1e() 3: use {rd,wr}{fs,gs}base when available 4: check for canonical address before doing page walks Signed-off-by: Jan Beulich <jbeulich@suse.com>

We have had some problems bringing up SLES10/Xen on DL360 box (dual processor). The Compaq boxes have this notion of "auto" mode for MPS/APIC to deal with buggy OSes and under this setting (which is the default setting), vanilla Linux (2.6.16) comes up on this box in UP mode since it finds the local APIC disabled in bios. However, the xen based kernel tries to come up MP and fails in a

Greg, A few days ago you applied all the outstanding patches for the Hyper-V drivers. With these patches, I have addressed all of the known review comments for the vmbus driver (and a lot of comments/issues in other drivers as well). I am still hoping I can address whatever other issues/comments there might be with the intention to get the vmbus driver out of staging in the current window.

I just took a quick look at the vmbus code, and have the following comments: - why is count_hv_channel() even a function? - your .h files need to be consolidated and renamed. You will need a single hyperv.h file for include/linux/ that will contain some of what the vmbus*.h files have in it, but not all. Please merge things together to have: - include/linux/hyperv.h What is

This is a repost of the RCU patch I have posted some time ago. The only change from the previous post, was to move it to a more recent version of xen-unstable (changeset 13386). I am planning to submit the following additional patches, after this one is accepted: 1) rename_find_domain.patch: Rename find_domain_by_id() to get_domain_by_id() 2) add_find_domain.patch: Add new

Could anyone summarize what the support status of cpu frequency changes is at present. I don''t seem to recall generic changes to the hpyervisor in that respect, but the linux tree has fairly extensive changes to the powernow-k8 driver (which would make sense to me only if all other cpufreq drivers are fully supported now, too). Thanks, Jan
