I would like to know whether all core i7 processor is of type x86_64.(as per wiki it says so)
I have a core i7 machine (from /proc/cpuinfo) where only 32bit kernel in installed on the same. Also, it has 32 bit gcc compiler installed.
If core i7 supports x86_64 kernel , I would like to install the same. I hope all the 32 bit binaries can run on x86_64 kernel , so I am not going to do anything with applications.
Now, My questions are:
whether core i7 supports x86_64?
How to install a 64 bit cross compiler in order to build a kernel (64 bit type). My machine is Fedora FC15.
I hope all 32 bit apps should work fine with this 64 bit kernel. ?
How to get 64 bit cross compiler for fedora (x86_64)?
Note, I am aware about cross compiling kernel.
