ACPICA: Debugger: Cleanup debugging outputs to dump name path without trailing underscores
ACPICA commit 51a49c2fb4a73f302a6df2b8ddc1350dd261684d It is better to use unified ASL path name to interact with the developers. There are following acpi_ns_build_normalized_pathname() users invoking it for debugging purposes (acpiexec test results are attached): 1. acpi_ut_display_init_pathname (acpi_ns_handle_to_pathname): --------------------------------------------- Initializing Region \_SB.H_EC.ECF2 --------------------------------------------- 2. acpi_ns_print_node_pathname (acpi_ns_handle_to_pathname): --------------------------------------------- - ex \_SB.H_EC._STA Evaluating \_SB.H_EC._STA --------------------------------------------- 3. acpi_ds_print_node_pathname (acpi_ns_handle_to_pathname): --------------------------------------------- - level 211b console - execute \M1 ... **** Exception AE_AML_UNINITIALIZED_ARG during execution of method [\M1] (Node 009CB6B8) --------------------------------------------- 4. acpi_ex_dump_reference_obj (acpi_ns_handle_to_pathname): --------------------------------------------- - dump \_TZ.FAN4._PR0 ... [00] 00835E98 [Object Reference] Type [Named Object] 05 00828878 \_TZ.FN04 --------------------------------------------- 5. acpi_db_bus_walk (acpi_ns_handle_to_pathname): --------------------------------------------- - businfo \_SB.PCI0 Type 6 ... --------------------------------------------- 6. acpi_db_walk_and_match_name (acpi_ns_handle_to_pathname): --------------------------------------------- - find _PR0 \_TZ.FAN4._PR0 Package 002D8DF8 01 Elements 01 --------------------------------------------- 7. acpi_db_walk_for_specific_objects (acpi_ns_handle_to_pathname): --------------------------------------------- - methods ... \_SB.PCI0._PRT Method 0026D918 01 Args 0 Len 0005 Aml 0026B199 ... --------------------------------------------- 8. acpi_db_decode_and_dispaly_object (acpi_get_name): --------------------------------------------- - gpes Block 0 - Info 003AC7B0 device_node 003A0E08 [\_GPE] - FADT-defined GPE block ... --------------------------------------------- 9. acpi_db_display_gpes (acpi_get_name): --------------------------------------------- - dump \_GPE Object (003A0E08) Pathname: \_GPE --------------------------------------------- 10.ae_miscellaneous_tests (acpi_get_name): No output available This patch cleans up all of the above usages. ACPICA BZ 1178, Lv Zheng. Linux kernel's ACPICA debugging messages may also be changed.
