similar to: Interrrupts and IPIs?

Hi I am using oprofile 0.9.3 on xen cs 16540 on an Intel system. When I look at the top "hot" functions, I see p2m_change_type being one of the top function in xen-syms. This function is only in the svm (AMD) code and should not appear on an Intel system. I see that this function is not being clled at all when I am running my apps as I have put printk in the functions and they do

Hi, this is almost an ia64 specific patch to xenperf. It makes xenperf output more understandable. On x86, it now displays hypercalls name. Tested on xen/ia64.

This patch pretty prints the hypercall section for $xenperf -f Each hypercall count is tagged by its name.

Hi All I want to use software counters available via "xenperf". However I get this error "Error getting number of perf counters: 38 (Function not implemented)". Am I missing something? Some configuration or option which needs to be turned on before I can use these counters. Any help would be much appreciated. I am using Xen 3.1.0 x86_64 -- Jyotirmaya Tripathi Virginia Tech

Also, rename to MOVE_CLEANUP_VECTOR to be in line with the other IPI names. This requires bumping LAST_HIPRIORITY_VECTOR, but does mean that the range FIRST-LAST_HIPRIORITY_VECTORs are free once again.

What is the point of specifying "current" as the address to monitor? The memory location of interest really is irq_stat[cpu].__softirq_pending, and if that was used it would then also be possible to actually avoid sending IPIs when monitor/mwait are in use, as is being done on Linux.

A fair few things under tools link against libraries which they don''t even use. Most of this appears to come from copy-and-pasting previous Makefile

In general the semantics of IPIs are that they are are expected to continue functioning after dpm_suspend_noirq(). Specifically I have seen a deadlock between the callfunc IPI and the stop
