Hi, I am really confused about NPT walks for guest page table , and eager to know the details about it. It is treated as data writes even if the access itself is a code read in AMD NPT.I just want to know : is it the same in EPT? Could anyone help me? I would like to know that very much Thank you in advance Bo Ma _____________...

The problem I am seeing is with any optimization higher than -O0 on the following code: void uxa_check_poly_lines(DrawablePtr pDrawable, GCPtr pGC, int mode, int npt, DDXPointPtr ppt) { ScreenPtr screen = pDrawable->pScreen; UXA_FALLBACK(("to %p (%c), width %d, mode %d, count %d\n", pDrawable, uxa_drawable_location(pDrawable), pGC->lineWidth, mode, npt)); if (pGC->lineWidth == 0) { if (uxa_prepare_access(pDrawable, UXA_...

Hi, guys Recently I have been doing some research & I''ve got in trouble. I have altered the kernel of domU and put the code section and data section of selinux security server which locate ~/security/selinux/ss into two seperate sections in the final vmlinux image(see below) objdump -h vmlinux vmlinux: file format elf32-i386 Sections: Idx Name Size VMA

Using R 2.0.1 on Windows XP, I am getting an error msg: Error in .Fortran("conic", nxy = nxy, npt = npt, CP = cp, EP1 = ep1, EP2 = ep2, : Fortran function name not in load table I am wondering if there is a way to see what function names are in the load table?

Okay, sounds great. I added it to the page with a note to that effect: http://llvm.cs.uiuc.edu/testresults/ Thanks a lot for volenteering to run it. Also, if you notice any big regressions or any...

There has been some progress, but still no joy. Definitely not intended for inclusion at this point. Tim, Wei, I added a Xen command line toggle to disable IOMMU and P2M table sharing. Tim, I verified that changes to p2m-pt.c don''t break shadow mode (64bit hypervisor and Win 7 guest). Hongkaixing, I incorporated your suggestion in patch 2, so I should add your Signed-off-by eventually.
