Hi. I rewrote the patch according to the comments. I adopted generating in-place code because it looks the quickest way. The point Eddie wanted to discuss is how to generate code and its ABI. i.e. in-place generating v.s. direct jump v.s. indirect function call Indirect function call doesn't make sense because ivt.S is compiled multi times. And it is up to pv instances to choose in-place

Hi. The patch I send before was too large so that it was dropped from the maling list. I'm sending again with smaller size. This patch set is the xen paravirtualization of hand written assenbly code. And I expect that much clean up is necessary before merge. We really need the feed back before starting actual clean up as Eddie already said before. Eddie discussed how to clean up and suggested

All, So far I've tried LLVM on amd64, i386, ia64 and powerpc under FreeBSD and aside for ia64, things look pretty good for a first try. There are 2 unexpected failures for PowerPC, which appear to be caused by uninitialized memory. I'm still working on a fix for that (need to brush up on my C++ skills). [sidenote: In FreeBSD -current, the memory allocator initializes memory with 0xa5

This patch set is intended for the next merge window. They are just enhancements of the already merged patches or ia64 porting from x86 paravirt techniques and that their quality is enough for merge. This patch set is for binary patch optimization for paravirt_ops. The binary patch optimization is important on native case because the paravirt_ops overhead can be reduced by converting indirect

Hi. This patchset implements xen/ia64 domU support. Qing He and Eddie Dong also has been woring on pv_ops so that I want to discuss before going further and avoid duplicated work. I suppose that Eddie will also post his own patch. So reviewing both patches, we can reach to better pv_ops interface. - I didn't changed the ia64 intrinsic paravirtulization abi from the last post. Presumably it

This patch set is for binary patch optimization for paravirt_ops. The binary patch optimization is important on native case because the paravirt_ops overhead can be reduced by converting indirect call into in-place execution or direct call. The first patch imports helper functions which themselves doesn't interesting things. The second patch replaces the indirect function calls with a

Hi. Thank you for comments on asm code paravirtualization. Its direction is getting clear. Although it hasn't been finished yet, I'd like to start discussion on ia64 intrinsics paravirtualization. This patch set is just for discussion so that it is a subset of xen Linux/ia64 domU paravirtualization, not self complete. You can get the full patched tree by typing git clone
