PowerPC 64-bit Kernel Internals
This presentation describes the internals of the new PowerPC 64-bit
Linux kernel. The new 64-bit PowerPC kernel is based on the preexisting
PowerPC 32-bit kernel, with major enhancements to the memory management
system including a new memory map, support for discontiguous physical
memory and a new mechanism for maintaining the coherency between the
hardware hashed page table and the Linux software page table. We'll
also describe the syscall design which includes a 32-bit syscall
interface which allows for execution of unmodified PowerPC 32-bit
binaries.
