Wed, 26 Mar 2025 13:42:07 +0100

Merge branch 'for-6.15/amd_sfh' into for-linusFrom: Mario Limonciello Some platforms include a human presence detection (HPD) sensor. Whenenabled and a user is detected a wake event will be emitted from thesensor fusion hub that software can react to.Example use cases are "wake from suspend on approach" or to "lockwhen leaving".This is currently enabled by default on supported systems, but userscan't control it. This essentially means that wake on approach isenabled which is a really surprising behavior to users that don'texpect it.Instead of defaulting to enabled add a sysfs knob that users canuse to enable the feature if desirable and set it to disabled bydefault.

936cf61c3ef5d6dad714d6c01a85704027dddeb9 - gendwarfksyms: Add support for kABI rules

Fri, 03 Jan 2025 21:45:35 +0100

gendwarfksyms: Add support for kABI rulesDistributions that want to maintain a stable kABI need the abilityto make ABI compatible changes to kernel without affecting symbolversions, either because of LTS updates or backports.With genksyms, developers would typically hide these changes fromversion calculation with #ifndef __GENKSYMS__, which would resultin the symbol version not changing even though the actual type haschanged. When we process precompiled object files, this isn't anoption.To support this use case, add a --stable command line flag thatgates kABI stability features that are not needed in mainlinekernels, but can be useful for distributions, and add support forkABI rules, which can be used to restrict gendwarfksyms output.The rules are specified as a set of null-terminated strings storedin the .discard.gendwarfksyms.kabi_rules section. Each rule consistsof four strings as follows: "version\0type\0target\0value"The version string ensures the structure can be changed in abackwards compatible way. The type string indicates the type of therule, and target and value strings contain rule-specific data.Initially support two simple rules: 1. Declaration-only types A type declaration can change into a full definition when additional includes are pulled in to the TU, which changes the versions of any symbol that references the type. Add support for defining declaration-only types whose definition is not expanded during versioning. 2. Ignored enumerators It's possible to add new enum fields without changing the ABI, but as the fields are included in symbol versioning, this would change the versions. Add support for ignoring specific fields. 3. Overridden enumerator values Add support for overriding enumerator values when calculating versions. This may be needed when the last field of the enum is used as a sentinel and new fields must be added before it.Add examples for using the rules under the examples/ directory.Signed-off-by: Sami Tolvanen Signed-off-by: Masahiro Yamada List of files: /linux/scripts/gendwarfksyms/Makefile

ab4439981f8549b013f4ea0b274b7c77c88ab4bc - gendwarfksyms: Add symtypes output

Fri, 03 Jan 2025 21:45:33 +0100

gendwarfksyms: Add symtypes outputAdd support for producing genksyms-style symtypes files. Processdie_map to find the longest expansions for each type, and use symtypesreferences in type definitions. The basic file format is similar togenksyms, with two notable exceptions: 1. Type names with spaces (common with Rust) in references are wrapped in single quotes. E.g.: s#'core::result::Result' 2. The actual type definition is the simple parsed DWARF format we output with --dump-dies, not the preprocessed C-style format genksyms produces.Signed-off-by: Sami Tolvanen Reviewed-by: Petr Pavlu Signed-off-by: Masahiro Yamada List of files: /linux/scripts/gendwarfksyms/Makefile

Fri, 03 Jan 2025 21:45:31 +0100

gendwarfksyms: Limit structure expansionExpand each structure type only once per exported symbol. Thisis necessary to support self-referential structures, which wouldotherwise result in infinite recursion, and it's sufficient forcatching ABI changes.Types defined in .c files are opaque to external users and thuscannot affect the ABI. Consider type definitions in .c files tobe declarations to prevent opaque types from changing symbolversions.Signed-off-by: Sami Tolvanen Reviewed-by: Petr Pavlu Signed-off-by: Masahiro Yamada List of files: /linux/scripts/gendwarfksyms/Makefile
