All the physical function (PF) registers are listed in the qdma_v4_0_pf_registers.csv available in the Register Reference File.

Tip: When you generate the IP in default mode, not all registers are exposed. For example, debug registers will be missing. Refer to the qdma_v4_0_pf_registers.csv file to identify the debug registers. To expose all registers, use the following tcl command during IP generation:

set_property CONFIG.debug_mode {DEBUG_REG_ONLY} [get_ips qdma_0]
