Previously, `acpi_wmi_notify_handler()` and `wmi_get_event_data()` shared more or less the exact same code to query the data for a particular event. Introduce a function to get rid of the duplication, and use it from `acpi_wmi_notify_handler()` and `wmi_get_event_data()`. Signed-off-by:

Introduce helper function to determine the appropriate ACPI type for the input parameter. This also fixes the following checkpatch warning: "braces {} are not necessary for any arm of this statement". Signed-off-by: -
Barnabás Pőcze authored
Instead of "manually" constructing the ACPI method name and hard-coding sizes in WMI functions, introduce a helper method which generates the method name for an arbitrary WMI block. Furthermore, save the appropriate buffer size into a macro. Signed-off-by:

Introduce a helper function which wraps the appropriate `container_of()` macro invocation to convert a `struct device_driver` to `struct wmi_driver`. Signed-off-by:

The current code carries out the following ACPI status mapping: AE_NOT_FOUND -> AE_OK AE_OK -> AE_OK AE_$X -> AE_$X That is, everything is mapped to itself, except AE_NOT_FOUND. The current code does not do it in the most straighforward way. Simplify the logic. Signed-off-by:

Previously, `__query_block()` would fail if the second WCxx method call failed. However, the WQxx method might have succeeded, and potentially allocated memory for the result. Instead of throwing away the result and potentially leaking memory, ignore the result of the second WCxx call. Signed-off-by:

Move some variables in order to keep them in the narrowest possible scope. Signed-off-by:

The `block` variable is assigned and only used once, the code shorter and probably clearer without it; so remove it. Signed-off-by:

As per the coding style guide, the preferred way to pass the size of objects to allocator functions is `sizeof(*p)`. Use that. Signed-off-by:
-
Barnabás Pőcze authored
Other parts of the code use the `!p` idiom to check for NULL pointers, convert `find_guid_context()` to do the same. Signed-off-by:

Instead of `sprintf()` use the new `sysfs_emit()` function. Signed-off-by:

The `guid_block` struct is overlaid onto a buffer coming from the _WDG ACPI object of the device. For this reason mark the struct packed and add assertions about sizes. Signed-off-by:

Instead of hard-coding a 16 long byte array, use the available `guid_t` type and related methods. Signed-off-by:
-
Barnabás Pőcze authored
The `bool` type is more expressive for a yes/no kind of value, so use that as the type of the `enable` parameter of `wmi_method_enable()`. Signed-off-by:

Instead of manually creating the bit masks, use the `BIT()` macro to do it. Signed-off-by:
-
Barnabás Pőcze authored
The `find_guid_context()` is only called from one place, and `wblock` and `wdriver` cannot be NULL there. So remove the currently redundant checks. Signed-off-by:
-
Barnabás Pőcze authored
Remove an empty line after the last statement in `acpi_wmi_notify_handler()` which serves no purpose. Signed-off-by:

Void pointers are implictly cast to arbitrary pointer types, so remove superfluous casts. Signed-off-by:
-
Barnabás Pőcze authored
The GUID block is available for `wmi_create_device()` through `wblock->gblock`. Use that consistently in the function instead of using a mix of `gblock` and `wblock->gblock`. Signed-off-by:

The `status` variable was assigned at the end, and then immediately returned. Remove it altogether, and return the previously assigned value directly. Signed-off-by:

Some pointers are initialized when they are defined, but they are almost immediately reassigned in the following lines. Remove these superfluous assignments. Signed-off-by:

Barnabás Pőcze authored
The empty initializer `{ }` is enough to properly initialize the terminating acpi_device_id entry in the device table, so use that. Signed-off-by: -

A number of upcoming notebook computer designs drive the internal display panel's backlight PWM through the Embedded Controller (EC). This EC-based backlight control can be plumbed through to an ACPI "WMAA" method interface, which in turn can be wrapped by WMI with the GUID handle 603E9613-EF25-4338-A3D0-C46177516DB7. Add a new driver, aliased to the WMAA WMI GUID, to expose a sysfs backlight class driver to control backlight levels on systems with EC-driven backlights. Signed-off-by:

This patch adds support for HP Omen laptops. It adds support for most things that can be controlled via the Windows Omen Command Center application. - Fan speed monitoring through hwmon - Platform Profile support (cool, balanced, performance) - Max fan speed function toggle Also exposes the existing HDD temperature through hwmon since this driver didn't use hwmon before this patch. This patch has been tested on a 2020 HP Omen 15 (AMD) 15-en0023dx. - V1 Initial Patch - V2 Use standard hwmon ABI attributes Add existing non-standard "hddtemp" to hwmon - V3 Fix overflow issue in "hp_wmi_get_fan_speed" Map max fan speed value back to hwmon values on read Code style fixes Fix issue with returning values from "hp_wmi_hwmon_read", the value to return should be written to val and not just returned from the function - V4 Use DMI Board names to detect if a device should use the omen specific thermal profile method. Select HWMON instead of depending on it. Code style fixes. Replace some error codes with more specific/meaningful ones. Remove the HDD temperature from HWMON since we don't know what unit it's expressed in. Handle error from hp_wmi_hwmon_init - V5 Handle possible NULL from dmi_get_system_info() Use match_string function instead of manually checking Directly use is_omen_thermal_profile() without the static variable.

There have been reports of approximately a 0.9%-1.7% failure rate in SMU communication timeouts with s0i3 entry on some OEM designs. Currently the design in amd-pmc is to try every 100us for up to 20ms. However the GPU driver which also communicates with the SMU using a mailbox register which the driver polls every 1us for up to 2000ms. In the GPU driver this was increased by commit 05516264 ("drm/amd/pm: increase time out value when sending msg to SMU") Increase the maximum timeout used by amd-pmc to 2000ms to match this behavior. This has been shown to improve the stability for machines that randomly have failures. Cc: stable@kernel.org Reported-by:

Add info for getting the firmware directly from the UEFI for the Chuwi Hi10 Plus (CWI527), so that the user does not need to manually install the firmware in /lib/firmware/silead. This change will make the touchscreen on these devices work OOTB, without requiring any manual setup. Also tweak the min and width/height values a bit for more accurate position reporting.

ACPI_PTR() is more harmful than helpful. For example, in this case if CONFIG_ACPI=n, the ID table left unused which is not what we want. Instead of adding ifdeffery here and there, drop ACPI_PTR() and unused acpi.h. Fixes: fdca4f16 ("platform:x86: add Intel P-Unit mailbox IPC driver") Reported-by:

It resolves a build issue that many people were hitting with your current tree, and Kees and others felt would be good to get merged before -rc1 comes out, to prevent them from having to constantly hit it as many development trees restart on -rc1, not older -rc releases.
