Hi, I''ve a quad-core x86_64 machine (Intel Xeon), with sse/mmx support. However, I want to disable sse/mmx support from HVM guests. How can I do this? Also, is it reasonable to expect illegal instruction fault in non-root VMX mode if a guest VM runs an application with sse/mmx instructions? Thanks, Ashish _______________________________________________ Xen-devel mailing list

...ns the result will *actually work*. The LLVM IR generated by llvm-gcc is very architecture dependent. Theoretically you could make a C compiler that was mostly C compliant and produced architecture independent LLVM IR. llvm-gcc is not this compiler, however.

...tatus .... Now, If the build systems generates .so files, then it will be difficult o actually generate fully arch-independent kernel code, isn't it? thanks, ashish On Sat, Sep 27, 2008 at 8:16 PM, Dale Johannesen <dalej at apple.com> wrote: > > On Sep 27, 2008, at 4:34 PM, Ashish Bijlani wrote: > >> Thanks for the help.

Hi, I'm trying to compile linux-2.6.23.16 with llvm-2.3. Is it at all possible? I get "Not an ELF" error. I pass "-emit-llvm" option to spit LLVM IR, which can be JITed at runtime $ make CROSS_COMPILE=llvm- CFLAGS="-O2 -emit-llvm" Error: not ELF make[2]: *** [scripts/mod/elfconfig.h] Error 1 make[1]: *** [scripts/mod] Error 2 make: *** [scripts] Error 2 using

...-array initializer Note that I use "-emit-llvm" option with llvm-gcc. Is this correct of am I missing something? How can I fix this error?

Hi, I'm trying to compile linux kernel with llvm to generate llvm ir (bitcode). It seems like llvm-ld doesn't accept any linker scripts. How do I deal with vmlinux.lds in such a case? How did people who have compiled linux kernel with llvm deal with this in the past? Thanks, Ashish

...test LLVM release version 2.3. This was indeed a bug in LLVM that I've. I fixed it using the patch you specified. Thanks!! There are no recursive loops anymore.

lustre-1.8 has OSD structures in place, what do I need to add in to make it work with OSD T10 standard? could anybody point me to some docs mentioning lustre internals - OSTs, OSSs, OBDs, and control flow when a read/write call is invoked by a client. thanks. -------------- next part -------------- An HTML attachment was scrubbed...
