This patch set is a v5 of the previous versions submitted here: [v4]: http://lwn.net/Articles/568988/ [v3]: https://lkml.org/lkml/2013/2/5/228 [v2]: http://lwn.net/Articles/531720/ [v1]: https://lkml.org/lkml/2012/12/18/108 [RFC]:https://patchwork.kernel.org/patch/1758921/ This patch set is based on Rui's -next tree, on top of commit 'c698a4492f01127ca90fc28cd5157f3d616fe4ff' This is tested on a Core-i5 running ubuntu 12.04. Changes since v4: * Cleaned up the thermal_release function; Now all kfree's are done in _unregister functions. * Kconfig option to selectively enable and use this new version of thermal_core.c * According to a previous comment from Rui, moved all new API's into a file named thermal_core_new.c Changes since v3: * Added a patch to conditionally do kfree(cdev) in thermal_release function. * Reworked all sysfs attributes to have one value per file This includes sensor_trip_* and map_weight* attributes. * Added 'lock' variable in thermal_zone structure to protect its members. * Added Documentation to all functions in thermal_core.c * Changes all strcpy() to strlcpy() * Used devm_kzalloc() in places where applicable * Address some buffer overflow conditions and contentions in tz->sensors and tz->cdevs. Changes since v2: * Reworked the map sysfs attributes in patch [5/8] * Dropped configuration for maximum sensors and cooling devices, through Kconfig. * Added __remove_trip_attr method * Renamed __clean_map_entry to __remove_map_entry for consistency in naming. Changes Since v1: * Removed kobject creation for thermal_trip and thermal_map nodes as per Greg-KH's comments. * Added ABI Documentation under 'testing'. * Modified the GET_INDEX macro to be more linux-like, thanks to Joe Perches. * Added get_[sensor/cdev]_by_name APIs to thermal.h This series contains 10 patches: Patch 1/10: Remove code from thermal_release function. Do kfree in _unregister functions. Patch 2/10: Creates new sensor level APIs Patch 3/10: Adds new cooling device APIs Patch 4/10: Creates new zone level APIs. The existing tzd structure is kept as such for clarity and compatibility purposes. Patch 5/10: Creates functions to add/remove a cdev to/from a zone. The existing tcd structure need not be modified. Patch 6/10: Adds sensorX_trip_[active/passive/hot/critical] sysfs nodes, under /sys/class/thermal/zoneY/. This exposes various trip points for sensorX present in zoneY. Patch 7/10: Adds mapY_* sysfs node. These attributes represent the relationship between various sensors and cooling devices in a thermal zone. Patch 8/10: Creates Documentation for the new APIs. A new file is created for clarity. Final goal is to merge with the existing file or refactor the files, as whatever seems appropriate. Patch 9/10: Add ABI documentation for sysfs interfaces introduced in this patch. Patch 10/10: A dummy driver that can be used for testing. This is not for merge. Thanks to Rui for helping me in resolving some Kconfig issues, related to this series.
