2025-01-17ACPI: platform_profile: Remove platform_profile_handler from exported symbolsKurt Borja
In order to protect the platform_profile_handler from API consumers, allocate it in platform_profile_register() and modify it's signature accordingly. Remove the platform_profile_handler from all consumer drivers and replace them with a pointer to the class device, which is now returned from platform_profile_register(). Replace *pprof with a pointer to the class device in the rest of exported symbols.

2023-02-02platform/surface: aggregator: Enforce use of target-ID enum in device ID macrosMaximilian Luz
Similar to the target category (TC), the target ID (TID) can be one value out of a small number of choices, given in enum ssam_ssh_tid. In the device ID macros, SSAM_SDEV() and SSAM_VDEV() we already use text expansion to, both, remove some textual clutter for the target category values and enforce that the value belongs to the known set. Now that we know the names for the target IDs, use the same trick for them as well. Also rename the SSAM_ANY_x macros to SSAM_SSH_x_ANY to better fit in.

2021-03-08platform/surface: aggregator: Make SSAM_DEFINE_SYNC_REQUEST_x define static ↵Maximilian Luz
functions The SSAM_DEFINE_SYNC_REQUEST_x() macros are intended to reduce boiler-plate code for SSAM request definitions by defining a wrapper function for the specified request. The client device variants of those macros, i.e. SSAM_DEFINE_SYNC_REQUEST_CL_x() in particular rely on the multi-device (MD) variants, e.g.: #define SSAM_DEFINE_SYNC_REQUEST_CL_R(name, rtype, spec...) \ SSAM_DEFINE_SYNC_REQUEST_MD_R(__raw_##name, rtype, spec) \ int name(struct ssam_device *sdev, rtype *ret) \ { \ return __raw_##name(sdev->ctrl, sdev->uid.target, \ sdev->uid.instance, ret); \ } This now creates the problem that it is not possible to declare the generated functions static via static SSAM_DEFINE_SYNC_REQUEST_CL_R(...) as this will only apply to the function defined by the multi-device macro, i.e. SSAM_DEFINE_SYNC_REQUEST_MD_R(). Thus compiling with `-Wmissing-prototypes' rightfully complains that there is a 'static' keyword missing. To solve this, make all SSAM_DEFINE_SYNC_REQUEST_x() macros define static functions. Non-client-device macros are also changed for consistency. In general, we expect those functions to be only used locally in the respective drivers for the corresponding interfaces, so having to define a wrapper function to be able to export this should be the odd case out.

2021-03-06platform/surface: Add platform profile driverMaximilian Luz
Add a driver to provide platform profile support on 5th- and later generation Microsoft Surface devices with a Surface System Aggregator Module. On those devices, the platform profile can be used to influence cooling behavior and power consumption. For example, the default 'quiet' profile limits fan noise and in turn sacrifices performance of the discrete GPU found on Surface Books. Its full performance can only be unlocked on the 'performance' profile.
