1Linux ACPI Custom Control Method How To
2=======================================
3
4Written by Zhang Rui <rui.zhang@intel.com>
5
6
7Linux supports customizing ACPI control methods at runtime.
8
9Users can use this to
101. override an existing method which may not work correctly,
11 or just for debugging purposes.
122. insert a completely new method in order to create a missing
13 method such as _OFF, _ON, _STA, _INI, etc.
14For these cases, it is far simpler to dynamically install a single
15control method rather than override the entire DSDT, because kernel
16rebuild/reboot is not needed and test result can be got in minutes.
17
18Note: Only ACPI METHOD can be overridden, any other object types like
19 "Device", "OperationRegion", are not recognized.
20Note: The same ACPI control method can be overridden for many times,
21 and it's always the latest one that used by Linux/kernel.
22
231. override an existing method
24 a) get the ACPI table via ACPI sysfs I/F. e.g. to get the DSDT,
25 just run "cat /sys/firmware/acpi/tables/DSDT > /tmp/dsdt.dat"
26 b) disassemble the table by running "iasl -d dsdt.dat".
27 c) rewrite the ASL code of the method and save it in a new file,
28 d) package the new file (psr.asl) to an ACPI table format.
29 Here is an example of a customized \_SB._AC._PSR method,
30
31 DefinitionBlock ("", "SSDT", 1, "", "", 0x20080715)
32 {
33 External (ACON)
34
35 Method (\_SB_.AC._PSR, 0, NotSerialized)
36 {
37 Store ("In AC _PSR", Debug)
38 Return (ACON)
39 }
40 }
41 Note that the full pathname of the method in ACPI namespace
42 should be used.
43 And remember to use "External" to declare external objects.
44 e) assemble the file to generate the AML code of the method.
45 e.g. "iasl psr.asl" (psr.aml is generated as a result)
46 f) mount debugfs by "mount -t debugfs none /sys/kernel/debug"
47 g) override the old method via the debugfs by running
48 "cat /tmp/psr.aml > /sys/kernel/debug/acpi/custom_method"
49
502. insert a new method
51 This is easier than overriding an existing method.
52 We just need to create the ASL code of the method we want to
53 insert and then follow the step c) ~ g) in section 1.
54
553. undo your changes
56 The "undo" operation is not supported for a new inserted method
57 right now, i.e. we can not remove a method currently.
58 For an overrided method, in order to undo your changes, please
59 save a copy of the method original ASL code in step c) section 1,
60 and redo step c) ~ g) to override the method with the original one.
61
62
63Note: We can use a kernel with multiple custom ACPI method running,
64 But each individual write to debugfs can implement a SINGLE
65 method override. i.e. if we want to insert/override multiple
66 ACPI methods, we need to redo step c) ~ g) for multiple times.
