similar to: vm live migration memory copy

Hi everyone, I am using libvirt 2.5.0. I'd like to enable the "perf events" to monitoring my vm performance such as l3 cache. But it failed with "error: argument unsupported: unable to enable host cpu perf event for cmt". 1. Could you please give some hints on how to check if my host CPU supports cmt,mbm, is it displayed in /proc/cpuinfo? 2. Does the kernel version matters

Hello, I'm seeking the solution to live storage migration using blockcopy. Previously, the "virsh undefine" is required before blockcopy. https://www.redhat.com/archives/libvirt-users/2015-October/msg00027.html QEMU has "block-dirty-bitmap-*" operations now, are there steps for the live storage migration using blockcopy without undefine? By the way, why's the purpose

Hi, I'm running into weird problems after switching from tdbsam to ldapsam user backend. I have transferred all local unix and samba groups with the sambaldap-tools scripts. The 'net groupmap list' command prints all group mappings correctly, and I also can use all the groups present in LDAP for setting local file ownerships. However these groups don't appear in the windows

Hello, I found some source code using llvm 2.5 that has a call to Module::getTypeName(Type*), which I can't find it anymore in llvm newer than 3.3, so how can I get the name of a type(e.g a user-defined structure) if we have Type* of that ? Besides, I checked that old llvm maintains a TypeSymbolTable that enabled type name look-up, so what's the replacement and mechanism of it in the

Hi, I wonder if the function "density" outputs the gaussian mixture formula that is estimated from the input data, assuming a gaussian model is used at each data point ? I want to take the derivative of the finally estimated gaussian mixture formula for further analysis. Thanks in advance for any help that you can offer me! Hui

> ​It looks like clang++ is complaining about the thrust library comes with cuda, The Thrust library that comes with CUDA is indeed not compatible with clang. We made a number of changes to Thrust to make it work with clang (it was relying on what we considered to be bugs in nvcc), but they're only available in the upstream Thrust: https://github.com/thrust/thrust. No promises that one

Hi, I was using a density estimation function as follows: > est <- KernSmooth::bkde(x3, bandwidth=10) When setting bandwidth less than 5, I got the error "longer object length, is not a multiple of shorter object length in: kappa * gcounts ". I wonder if there is anybody who can explain the error for me? Thanks! Hui

Hello, I'm a little confused by the definition of metadata node: does it have to contain different types of data ? And does a named metadata have to have a string name ? I know the named metadata can only contain metadatas e.g. !3=metadata !{metadata !1, metadata !2} Does it belong to NamedMDNode or MDNode ? Thanks! -- Best regards Hui Zhang -------------- next part -------------- An

Hello, Do you know where I can find the correct metadata layout in the source code package (which file)? I found a source code that used llvm 2.5 following a slightly different metadata layout as what I read on http://llvm.org/docs/SourceLevelDebugging.html#debugger-intrinsic-functions, which should be compatible with the latest 3.6 version, so where can I check the detailed difference in each

Hello, I'm having this assertion fail when I was using DIBuilder to create the debug information: Expected no forward declarations! !719 The assertion condition is: !isa<MDNodeFwdDecl> (MD) So My questions are: 1. What is exactly the MDNodeFwdDecl ? I saw it's in the latest release 3.6.1, but I also found this link

Hello, I don't know if anyone gets familiar with the llvm Chapel front end, it's version 3.3 and comes within Chapel source package. I'm trying to parse the .bc code generated from a simple helloworld chapel program. Just run a basic Hello pass on the code (default one in the llvm source code) that prints out all the function names in the module. However, it prints a bunch of

Hello, I found a function call Function::isDeclaration() in llvm 2.5 (I know that's ancient...), which is useful to me, but I can't find it in the later version 3.3, nor the latest 3.7.....Therefore, is there an alternative way to check whether the function is just a declaration or a definition ? PS: I read the source code of llvm 2.5, and found isDeclaration is simply to check if the

Hello, For some reason, I have to stick on llvm 3.3 for a language compiler, I find that the location debug info is attached to each instruction using !dbg, however, I found some of that information is mis-attched and need to be changed, so I want to *know what functions(I checked all funcs in DIBuilder.h but didn't find a appropriate one) are used to attach those !dbg nodes to each
