ACPI: bus: Add stub acpi_sleep_state_supported() in non-ACPI cases

2023-04-17T19:16:22Z

acpi_sleep_state_supported() is defined only when CONFIG_ACPI=y. The function is in acpi_bus.h, and acpi_bus.h can only be used in CONFIG_ACPI=y cases. Add the stub function to linux/acpi.h to make compilation successful for !CONFIG_ACPI cases. Signed-off-by: Saurabh Sengar Acked-by: Rafael J.

ACPI: Replace irqdomain.h include with struct declarations

2023-04-06T18:36:27Z

linux/acpi.h includes irqdomain.h which includes of.h. Break the include chain by replacing the irqdomain include with forward declarations for struct irq_domain and irq_domain_ops which is sufficient for acpi.h. of.h also includes mod_devicetable.h which many drivers implicitly depend on. As acpi.h already includes it, just move it out of the '#ifdef CONFIG_ACPI'. Reviewed-by: Jacob Keller Reviewed-by: Greg Kroah-Hartman Signed-off-by: Rob Herring Signed-off-by: Rafael J. Wysocki

Merge tag 'driver-core-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2023-02-24T20:58:55Z

Pull driver core updates from Greg KH: "Here is the large set of driver core changes for 6.3-rc1. There's a lot of changes this development cycle, most of the work falls into two different categories: - fw_devlink fixes and updates. This has gone through numerous review cycles and lots of review and testing by lots of different devices. Hopefully all should be good now, and Saravana will be keeping a watch for any potential regression on odd embedded systems. - driver core changes to work to make struct bus_type able to be moved into read-only memory (i.e. const) The recent work with Rust has pointed out a number of areas in the driver core where we are passing around and working with structures that really do not have to be dynamic at all, and they should be able to be read-only making things safer overall. This is the contuation of that work (started last release with kobject changes) in moving struct bus_type to be constant. We didn't quite make it for this release, but the remaining patches will be finished up for the release after this one, but the groundwork has been laid for this effort. Other than that we have in here: - debugfs memory leak fixes in some subsystems - error path cleanups and fixes for some never-able-to-be-hit codepaths. - cacheinfo rework and fixes - Other tiny fixes, full details are in the shortlog All of these have been in linux-next for a while with no reported problems" [ Geert Uytterhoeven points out that that last sentence isn't true, and that there's a pending report that has a fix that is queued up - Linus ] * tag 'driver-core-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (124 commits) debugfs: drop inline constant formatting for ERR_PTR(-ERROR) OPP: fix error checking in opp_migrate_dentry() debugfs: update comment of debugfs_rename() i3c: fix device.h kernel-doc warnings dma-mapping: no need to pass a bus_type into get_arch_dma_ops() driver core: class: move EXPORT_SYMBOL_GPL() lines to the correct place Revert "driver core: add error handling for devtmpfs_create_node()" Revert "devtmpfs: add debug info to handle()" Revert "devtmpfs: remove return value of devtmpfs_delete_node()" driver core: cpu: don't hand-override the uevent bus_type callback. devtmpfs: remove return value of devtmpfs_delete_node() devtmpfs: add debug info to handle() driver core: add error handling for devtmpfs_create_node() driver core: bus: update my copyright notice driver core: bus: add bus_get_dev_root() function driver core: bus: constify bus_unregister() driver core: bus: constify some internal functions driver core: bus: constify bus_get_kset() driver core: bus: constify bus_register/unregister_notifier() driver core: remove private pointer from struct bus_type ...

driver core: make struct device_type.uevent() take a const *

2023-01-27T12:45:36Z

The uevent() callback in struct device_type should not be modifying the device that is passed into it, so mark it as a const * and propagate the function signature changes out into all relevant subsystems that use this callback.

ACPI: utils: Add acpi_evaluate_dsm_typed() and acpi_check_dsm() stubs

2023-01-20T13:25:17Z

When the ACPI part of a driver is optional the methods used in it are expected to be available even if CONFIG_ACPI=n. This is not the case for _DSM related methods. Add stubs for acpi_evaluate_dsm_typed() and acpi_check_dsm() methods. Reported-by: kernel test robot Signed-off-by: Andy Shevchenko Signed-off-by: David S. Miller

ACPI: Implement a generic FFH Opregion handler

2022-11-14T18:09:07Z

This registers the FFH OpRegion handler before ACPI tables are loaded. The platform support for the same is checked via Platform-Wide OSPM Capabilities(OSC) before registering the OpRegion handler. It relies on the special context data passed to offset and the length. However the interpretation of the values is platform/architecture specific. This generic handler just passed all the information to the platform/architecture specific callback. It also implements the default callbacks which return as not supported.
