similar to: [PATCH][SVM] remove FFXSR CPUID bit for AMD-V HVM guests

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),

I recently realized that the original way of dealing with the DebugCtl MSR on VMX failed to make use of the dedicated guest VMCS field. This is being fixed with this patch. What is puzzling me to a certain degree is that while there is a guest VMCS field for this MSR, there''s no equivalent host load field, but there''s also no indication that the MSR would be cleared during a

Svm patch to add 32bit msr support (combined both 32bit with 64bit functions) and enable vlapic for 64bit. Applies cleanly to 9023. Please apply.

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

x86:x2apic: Disable x2apic on x86-32 permanently x2apic initialization on x86_32 uses vcpu pointer before it is initialized. As x2apic is unlikely to be used on x86_32, this patch disables x2apic permanently on x86_32. It also asserts the sanity of vcpu pointer before dereference to prevent further misuse.

Implement tsc adjust feature IA32_TSC_ADJUST MSR is maintained separately for each logical processor. A logical processor maintains and uses the IA32_TSC_ADJUST MSR as follows: 1). On RESET, the value of the IA32_TSC_ADJUST MSR is 0; 2). If an execution of WRMSR to the IA32_TIME_STAMP_COUNTER MSR adds (or subtracts) value X from the TSC, the logical processor also adds (or subtracts) value X

Keir, The following 3 patches allow HVM (SVM and VT) guests to be passively profiled using the very latest patches from Renato. These patches apply to 11470. Renato''s patches: http://xenoprof/sourceforge.net oprofile-0.9.1-xen-r2.patch And also a patch not posted FAIK (oprofile-0.9.1-fix-hvm-addr-overlap.patch) which is in the attached tar.bz2 file. hvm_xenoprofile_1.patch - The first

Is it intentional that - under SVM, 32-bit guests can freely set EFER.LME - under VMX, 32-bit guests can''t access EFER at all? Thanks, Jan _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Keir, below/attached patch is necessary to allow SVM partitions to boot unmodified guests with xen-unstable.hg c/s 8961. c/s 8822 and 8828 (some necessary evtchn modifications) cause SVM partitions to fail with "lost interrupt" hda error during boot. We currently do not understand why these modifications are necessary and in fact, a race occurs with one part of the patch (added

Attached simple patch modifies the rombios and hvmloader Makefiles to default to an 8-way bochs bios for the hvmloader. Is there a reason to not define the mp config table by default for >1 processors (8), in the repository? Seems like using the hvm guest config file can the methodolody to describe a UP guest regardless of the mptables. Defaulting the rombios to MP would allow users to

Patch 2/2 - Add flag to indicate that an exception event needs injecting, and to delay the ext interrupt injection. Remove unnecessary check of RFLAGS.IF for ExtInt injection. Applies cleanly to xen-unstable c/s 11831. Please apply to xen-unstable.hg. We would also want this patch to be in a 3.0.3-1 base whenever that is branched.
