Hi, I ran into a problem when running DSA on Linux kernel (the Kernel version I used is 2.4.31). The analysis was aborted when it tried to do DSNode::mergeTypeInfo on some data structure in the kernel. I have filed a bug report at http://llvm.org/bugs/show_bug.cgi?id=1656. My question is what version of Linux kernel LLVM has been tested on successfully? To run DSA analysis, should I use the

I want to know any difference between writing, reading and shadow page table (for example performance). I am thankful for any help or resource for that. -- Best Regards Mohamad Taghi Mir Mohamad Rezaie Iran University of Science and Technology Department of Computer Science & Engineering System Software Group _______________________________________________ Xen-devel mailing list

A following question about how to install "poolalloc". I checked out poolalloc from svn. But I had a problem of installing it. When I tried to run "configure" with options "--with-llvmsrc" and "--with--llvmobj" pointing to where the source of my llvm and objs dir are (/home/usr/Tools/llvm, e.g.), "configure" complained error message

In order to be meaningful and usable together with other measuring methods, their use in my opinion should impose as little overhead as possible. With that, I wonder why per-cpu counters use atomic operations.

Hi, I am curious about if the current LLVM implementation can handle Linux kernel (or any particular version of Linux kernel). The first question I have is that, how to create LLVM bytecode of Linux kernel using LLVM gcc frontend. What changes should I make to the compiling process Linux kernel? Secondly, is it possible to compile the assembly code in Linux kernel into LLVM bytecode? I noticed

okay. I guess I figured it out. It seems "poolalloc" needs to be put in llvm/projects/ directory.

hi. trying to understand the idea behind _notify in #define RING_PUSH_REQUESTS_AND_CHECK_NOTIFY(_r, _notify) do { \ RING_IDX __old = (_r)->sring->req_prod; \ RING_IDX __new = (_r)->req_prod_pvt; \ wmb(); /* back sees requests /before/ updated producer index */ \ (_r)->sring->req_prod = __new;

Hi, I implemented my own Hypercall in xen. Now I wish my application under dom0 could talk to Xen via my hypercall. Currently, I make a stub in dom0''s kernel, which works as a proxy to forward the request. So, my application first makes a system call to dom0, which then makes hypercall to xen. Is this design necessary? May I call hypercalls from user application under dom0 directly?

LLVM3.8 version. https://bugs.llvm.org//show_bug.cgi?id=24233. The example can catch exception. But I use my own code for testing, CustomEHMemoryManager allocated memory address is very large, allocateCodeSection, allocateDataSection assigned address (more than 32 bit address space) is getting smaller and smaller. Cause registerEHFrames to fail. 3.9.1 or 4.0.0 version has been supported on win

hi, all: i want to add a function in xen. in the function i need to call the "printk" to display the values of some variables. i found the definition of printk() in file "xen-3.1.0-src\xen\include\xen\lib.h ": extern void printk(const char *format, ...) __attribute__ ((format (printf, 1, 2))); who can tell me the location of printk()? thanks in advance. 2008-04-26

Hi, I''m trying to use the SYSCALL/SYSRET opcodes with a minios kernel without much success. Going by the manuals (and linux sources) I first have to setup the STAR and LSTAR registers to define the segment and instruction pointer to be used for SYSCALL: /* * LSTAR and STAR live in a bit strange symbiosis. * They both write to the same internal register. STAR allows

Hi I have a doubt regarding Mini-OS and Xen. If it is true that Xen reserves in the virtual address space the top 64MB on 32bit systems and 168MB in PAE systems, doesn''t it exist with a Mini-OS kernel which has only 32MB in size i.e. going by its default config file? Obviously I''m missing something. Regards, Bhaskar. _______________________________________________ Xen-devel

I was following an email chain in the xen mailing list on HVM hypercalls on grant tables and the email chain link is below http://lists.xensource.com/archives/html/xen-devel/2007-03/msg00688.html This link says that we need not required hypercalls to share memory b/w HVM''s. But as far as my understanding of sharing memory is concerned, I think the memory is shared using grant table

For help: Llvm generated instruction calls a function (extern), the function will have a SEH exception (EXCEPTION_ACCESS_VIOLATION), But JIT can not capture the exception of the EXCEPTION_ACCESS_VIOLATION. I saw Bug 24233. EXCEPTION_ACCESS_VIOLATION exception cannot be captured after modification. How to catch EXCEPTION_ACCESS_VIOLATION exceptions on win64 ? haifeng.qin at wellintech.com

Get blktap2 running on pvops. This mainly adds eventfd support to the userland code. Based on some prior cleanup to tapdisk-queue and the server object. We had most of that in XenServer for a while, so I kept it stacked. 1. Clean up IPC and AIO init in tapdisk-server. [I think tapdisk-ipc in blktap2 is basically obsolete. Pending a later patch to remove it?] 2. Split tapdisk-queue into

Hi, Maybe it''s a dumb question, but I''m actually trying to understand how the memory allocation works within Xen. I try to give 128MB to a domU and see if it increases for example when I "nano" a 500mb file, but the process just get killed when it reachs the 128MB memory limit. How do I configure the guests so they can ask for more memory until a limit is reached

Hi, Sometimes when I mount a disk image, unmount it, and then try to create a domU using the disk image I get the following error: Error: Device 2049 (vbd) could not be connected. Backend device not found. Im using a FC4 image. Here is the config file: kernel = "/boot/vmlinuz-2.6.16-rc3-xenU" memory=256 name=Domain1 vif = [''bridge=xenbr0''] disk = [
