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

Changes from v1: - Define new struct hvm_trap to represent information of trap, include instruction length. - Renames hvm_inject_exception to hvm_inject_trap. Then define a couple of wrappers around that function for existing callers, so that their parameter lists actually *shrink*. This series of patches fix the mistake for debug exception(#DB), overflow exception(#OF) and INT3(#BP),

From: Yang Zhang <yang.z.zhang@Intel.com> The following patches fix the issue that fail to boot L2 guest on APIC-v available machine. The main problem is that with APIC-v, virtual interrupt inject L1 is totally through APIC-v. But if virtual interrupt is arrived when L2 is running, L1 will detect interrupt through vmexit with reason external interrupt. If this happens, we should update

This series of patches fix the mistake for debug exception(#DB), overflow exception(#OF) and INT3(#BP), INTn instruction emulation. Introduce new function vmx_inject_sw_exception() which deliver the software excetion, software interrupt and privileged software exception. Split hardware exception as a seperate function(old function vmx_inject_hw_exception()). Also Passed down intruction length
