Have you settled on a #define for configuring in PAE code, eg. CONFIG_X86_PAE like linux. Are you adding this or something else to asm-x86/config.h Have you determined if the PAE code is going into the files under xen/arch/x86/x86_32, using #ifdef's for PAE, or are you planning to add a parallel directory to x86_32 and x86_64 under xen/arch? Same question for headers. Are you adding the 3-level page tables to the existing include/asm-x86/x86_32/page.h using #ifdef's or adding a new directory parallel to x86_32 and x86_64 which would have a new page.h, etc? > There are a few things that need to be sorted to get PAE to work: > * add 3-level type checking to Xen (this should be easy as it already > supports 2 and 4 level) Is this adding the 3-level page tables to the header files? Not sure what you mean by type checking. If not, what do you mean by this? > > * add 3-level support to Linux arch Xen (this should be easy as the > there are very few modifications to the mm system these days) > Thanks, Karen ------------------------------------------------------- This SF.net email is sponsored by: 2005 Windows Mobile Application Contest Submit applications for Windows Mobile(tm)-based Pocket PCs or Smartphones for the chance to win $25,000 and application distribution.
