A. Build the AML debugger In order to build the kernel support of AML debugger, the following kconfig items should be enabled: CONFIG_ACPI_DEBUG=y CONFIG_ACPI_DEBUGGER=y CONFIG_DEBUG_FS=y CONFIG_ACPI_DEBUGGER_USER=m The userspace tool can be found at tools/power/acpi/tools/acpidbg. To build this utility, staying in tools folder and type "make acpi". B. Load the AML debugger during runtime In order to use the in-kernel AML debugger, the following command should be executed using root user: # modprobe acpi_dbg # mount -t debugfs none /sys/kernel/debug # acpidbg C. Batch mode In order to support scripts, the userspace utility also supports single command batch mode: # acpidbg -b "help" # acpidbg -b "tables" # acpidbg -b "find _LID" # acpidbg -b "execute \_SB.LID0._LID" You can find the documentation about the ACPICA debugger commands in: https://acpica.org/sites/acpica/files/acpica-reference_17.pdf (The latest document can be found at https://acpica.org/documentation) And refer to the chapter - ACPICA debugger reference to obtain the full description of the debugger commands. Note that not all commands are supported by an in-kernel AML debugger. D. Unload the AML debugger during runtime After terminating all acpidbg instances, the following command can be executed to remove the AML debugger from kernel: # rmmod acpi_dbg The following tasks are not completed: 1. .flush() support in the kernel debugger IO driver. 2. multi-commands batch mode. v2: 1. Fix a help message issue for the userspace acpidbg utility (this is a typo fix). 2. Fix a batch mode issue by adding "\n" to the prompt sequence (this was lost due to too many rebase cycles). 3. Fix kconfig dependency for an intermediate patch (this is only useful in case the latter patches are reverted). 4. Add more accurate runtime debugger stub mechanism and remove old ACPI_DEBUGGER_EXEC() stub mechanism. 5. Add x86 acpi_os_readable() support. v3: 1. Remove acpi_os_readable() support from this patchset. It's sent separately. 2. Delete some deprecated comments. v4: 1. Rebase patch 4/6 because of Kconfig changes. 2. Include acpi_os_readable() back as no objections, also test result is positive.
