The remoteproc core creates certain standard debugfs entries, that does not give a whole lot of useful information for the PRUs. The PRU remoteproc driver is enhanced to add additional debugfs entries for PRU. These will be auto-cleaned up when the parent rproc debug directory is removed. The enhanced debugfs support adds two new entries: 'regs' and 'single_step'. The 'regs' dumps out the useful CTRL sub-module registers as well as each of the 32 GPREGs and CT_REGs registers. The GPREGs and CT_REGs though are printed only when the PRU is halted and accessible as per the IP design. The 'single_step' utilizes the single-step execution of the PRU cores. Writing a non-zero value performs a single step, and a zero value restores the PRU to execute in the same mode as the mode before the first single step. (note: if the PRU is halted because of a halt instruction, then no change occurs). Logic for setting the PC and jumping over a halt instruction shall be added in the future.
