While looking in kgdb patch source, I found frequent use of registers db0, db1... and dr6, dr7 etc in inline assembly code. Which are these registers? I know registers eax, ebx etc but never heard of these. Are these same registers? If yes, then what is mapping? Regards Mohanlal -- Kernelnewbies: Help each other learn about the Linux kernel.
