Can someone help me?
Usually one does not use the debug registers directlym but instead
uses one of the drivers that controls them.
for example the pmcstat program gives you access to the process
accounting registers and control 'virtual' counters per process.
gdb (via the kernel) and other debug tools use various registers, so
you want to make sure you are not interfering with them either.
