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

Remove the do_nmi() call from the vmexit logic, as the NMI is held pending and will be handled in the context of the host when the STGI instruction is executed. This patch only modifies AMD-V code. This patch is required even without the other Xenoprofile patches applied. Applies cleanly to c/s 11831. Please apply to xen-unstable.hg regardless of the other patches. We also want these patches

Third patch (VT) for hvm xenoprofile support. Applies cleanly to 11470. Signed-off-by: Tom Woller <thomas.woller@amd.com> Please apply to xen-unstable.hg. hvm_xenoprofile_3.patch - The third patch adds the actual xenoprofile fixes for VT: I checked (verified by Renato), that the VT traces look ok also. There is some code that I am unsure about in the vmx_oprofile_get_eip(): i.e using the

Add xenoprofile function to oprofile to obtain the mode, adding check for hvm guest. Applies cleanly to xen-unstable c/s 11831. Please apply to xen-unstable.hg. We also want these patches to be in a 3.0.3-1 base whenever that is branched.

Renato, If one creates an HVM domain (say domain 1) and then does echo 1 > /dev/oprofile/passive_domains one then gets the following on the Xen serial console: (XEN) xenoprof.c:143:d0 xenoprof/x86 with autotranslated mode enabledisn''t supported yet (XEN) xenoprof.c:143:d0 xenoprof/x86 with autotranslated mode enabledisn''t supported yet (XEN) xenoprof.c:143:d0

Correct compile time compare of CONFIG_PAGING_LEVELS for 64bit and 32bit PAE guests. This code affects accesses to the CR4 register by the SVM guest. Applies cleanly to 10729 + posted NMI/STGI SVM patch. Please apply to xen-unstable.hg.

.. for both 32-bit apps in 64-bit pv guests and 32on64. This patch depends on more than just guest_context saved/restored as guest state during save/restore/migrate (namely the new fields holding callback addresses). Since the 32-bit kernel doesn''t make use of syscall (it would be possible to do so now, when running on a 64-bit hv), the compat mode guest code path for syscall

This adds support for core and core2 chips. Tested on Woodcrest processors. Requires Oprofile 0.9.2. -Andrew Signed-off-by: Andrew Theurer <habanero@us.ibm.com> _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi, I want to get the performance data like documents <<Xenoprofoverview&Networking Performance Analysis>> (http://www.xensource.com/files/xs0106_xenoprof.pdf ). But how can I get the modules'' profile in kernel? Now I use command: Opcontrol --no-vmlinux --separate=kernel,cpu --start-daemon ...run benchmark Opcontrol --sutdown Opreport >list The report shows: CPU:

Basic infrastructure for Xen S3 support with a common CPU context save/restore logic for both 32bit and 64bit. Wakeup code is split into two parts: - the first locates after trampoline code, to share all the tricks on the latter, like relocation base and identy mapping - the 2nd part locates in xen code segment, to do the actual CPU context restore Signed-off-by Ke Yu

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.

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

SVM patch to add a host save area per core for the hypervisor and also for the microcode. The microcode area is not guaranteed to be compatible with the vmcb layout, therefore will require it''s own "scratch pad". Consolidate the per core areas into a single structure. Applies cleanly to 10002. Please apply to xen-unstable.hg. Please apply to xen-3.0-testing.hg.

AMD-V does not require the delaying of interrupt injection if the guest IF_FLAG disallows interrupts. Remove the code in svm_intr_assist() that was checking the guest IF in eflags. This patch fixes the problem with HVM Windows guests, with observing a very slow timer countdown on the initial boot menu, when there is more than one boot option. Kbd response in this same Windows boot menu is also
