Detailed Description

This wraps an implementation of DPM primitives.

Each interface provider supplies a structure like this, which is the glue between upper level code and the lower level hardware access.

It is a PRELIMINARY AND INCOMPLETE set of primitives, starting with support for CPU register access.

◆ bpwp_disable

int(* arm_dpm::bpwp_disable) (struct arm_dpm *dpm, unsigned index_value)

Disables one breakpoint or watchpoint by clearing its hardware control registers.

Indices are the same ones accepted by bpwp_enable().
