Hi, I got a problem when I am trying to insert a call function with pointer arguments. The function C proto-type is the following, void stat_func(char *); >ConstantArray *Cstr = dyn_cast<ConstantArray>(gI->getInitializer()); ...... >Function *exFunc = M->getOrInsertFunction("stat_func", Type::VoidTy, PointerType::get(Type::SByteTy),0); >std::vector<Value*> Args(1); >Args[0] = constantArray::get(Cstr-&...

The current QEMU live migration implementation mark the all the guest's RAM pages as dirtied in the ram bulk stage, all these pages will be processed and that takes quit a lot of CPU cycles. >From guest's point of view, it doesn't care about the content in free pages. We can make use of this fact and skip processing the free pages in the ram bulk stage, it can save a lot CPU cycles

Hi, This series targets automatic boot menu generation, but most of it is the Lua upgrade, because I got tired reading deprecated API docs. It's mostly a straightforward forward port of the earlier Syslinux specific changes to Lua 5.1, except that: * I chose the add a stub getenv() implementation to the COM32 API instead of #ifdefing out all the references in Lua, and * I kept oslib
