Detailed Description
Implements various ARM DPM operations using architectural debug registers.
These routines layer over core-specific communication methods to cope with implementation differences between cores like ARM1136 and Cortex-A8.
The "Debug Programmers' Model" (DPM) for ARMv6 and ARMv7 is defined by Part C (Debug Architecture) of the ARM Architecture Reference Manual, ARMv7-A and ARMv7-R edition (ARM DDI 0406B). In OpenOCD, DPM operations are abstracted through internal programming interfaces to share code and to minimize needless differences in debug behavior between cores.

◆ armv8_dpm_read_current_registers()
| int armv8_dpm_read_current_registers | ( | struct arm_dpm * | dpm | ) |
Read basic registers of the current context: R0 to R15, and CPSR in AArch32 state or R0 to R31, PC and CPSR in AArch64 state; sets the core mode (such as USR or IRQ) and state (such as ARM or Thumb).
In normal operation this is called on entry to halting debug state, possibly after some other operations supporting restore of debug state or making sure the CPU is fully idle (drain write buffer, etc).
