WMI drivers can if they have specified an array of struct wmi_device_id use the MODULE_DEVICE_TABLE() macro to automatically generate the appropriate MODULE_ALIAS() output. Thus avoiding to keep both the array of struct wmi_device_id and the MODULE_ALIAS() declaration(s) in sync. Change driver to use MODULE_DEVICE_TABLE() instead of MODULE_ALIAS(). Signed-off-by:

The kernel provides the macro MODULE_DEVICE_TABLE() where driver authors can specify their device type and their array of device_ids and thereby trigger the generation of the appropriate MODULE_ALIAS() output. This is opposed to having to specify one MODULE_ALIAS() for each device. The WMI device type is currently not supported. While using MODULE_DEVICE_TABLE() does increase the complexity as well as spreading out the implementation across the kernel, it does come with some benefits too; * It makes different drivers look more similar; if you can specify the array of device_ids any device type specific input to MODULE_ALIAS() will automatically be generated for you. * It helps each driver avoid keeping multiple versions of the same information in sync. That is, both the array of device_ids and the potential multitude of MODULE_ALIAS()'s. Add WMI support to MODULE_DEVICE_TABLE() by adding info about struct wmi_device_id in devicetable-offsets.c and add a WMI entry point in file2alias.c. The type argument for MODULE_DEVICE_TABLE(type, name) is wmi. Suggested-by:

In preparation for adding WMI support to MODULE_DEVICE_TABLE() move the definition of struct wmi_device_id to mod_devicetable.h and inline guid_string in the struct. Changing guid_string to an inline char array changes the loop conditions when looping over an array of struct wmi_device_id. Therefore update wmi_dev_match()'s loop to check for an empty guid_string instead of a NULL pointer. Signed-off-by:

On some platforms such as HP Elite-x2-1013-g3, the platform BIOS enforces XTAL to remain off before S0ix state can be achieved. This may not be optimum when we want to enable use cases like Low Power Audio, Wake on Voice etc which always need 24mhz clock. This introduces a new quirk to allow S0ix entry when all other conditions except for XTAL clock are good on a given platform. The extra power consumed by XTAL clock is about 2mw but it saves much more platform power compared to the system that remains in just PC10.

This patch introduces a new debugfs entry to read current Package cstate residency counters. A similar variant of this patch was discussed earlier "https://patchwork.kernel.org/patch/9908563/" but didn't make it into mainline for various reasons. Current version only adds debugfs entry which is quite useful for S0ix debug but excludes the exported API that was there in initial version. Though there are tools like turbostat and socwatch which can also show this info but sometimes its more practical to have it here as it's hard to switch between various tools for S0ix debug when pmc_core driver is the primary debug tool. Internal and external customers have requested for this patch to be included in the PMC driver on many occasions and Google Chrome OS team has already included it in their builds. This becomes handy when requesting logs from external customers who may not always have above mentioned tools in their integrated kernel builds. Package cstate residency MSRs provide useful debug information about system idle states. In idle states system must enter deeper Package cstates. Package cstates depend not only on Core cstates but also on various IP block's power gating status and LTR values. For Intel Core SoCs Package C10 entry is a must for deeper sleep states such as S0ix. "Suspend-to-idle" should ideally take this path: PC0 -> PC10 -> S0ix. For S0ix debug, its logical to check for Package C10 residency first if for some reason system fails to enter S0ix. Please refer to this link for MSR details: https://software.intel.com/sites/default/files/managed/22/0d/335592-sdm-vol-4.pdf Usage: cat /sys/kernel/debug/pmc_core/package_cstate_show Package C2 : 0xec2e21735f Package C3 : 0xc30113ba4 Package C6 : 0x9ef4be15c5 Package C7 : 0x1e011904 Package C8 : 0x3c5653cfe5a Package C9 : 0x0 Package C10 : 0x16fff4289 Cc: Arjan van de Ven <arjan@linux.intel.com> Cc: "David E.

The register (SLP_S0_RES) at offset slp_s0_offset is a 32 bit register. The pmc_core_adjust_slp_s0_step() could overflow the u32 value while returning it after adjusting the step.

Add support for capability register in order to distinct between the systems with minor LED configuration differences. It reduces the amount of code describing systems' LED configuration. For example one system can be equipped with six LED, while the other with only four. Reading this information from the capability registers allows to use the same LED structure for such systems and set the relevant configuration dynamically based on capability register content.

For some odd reason dell_rbu actually seems to want the physical and not a bus address for the allocated buffer. Lets assume that actually is correct given that it is BIOS-related and that is a good source of insanity. In that case we should not use dma_alloc_coherent with a NULL device to allocate memory, but use GFP_DMA32 to stay under the 32-bit BIOS limit. Signed-off-by:

hid-asus depends on asus-wmi through the asus_wmi_evaluate_method. Before this commit asus-wmi, and thus hid-asus, could not be loaded on non-Asus systems. This breaks using Asus bluetooth keyboards such as the Asus T100CHI keyboard with non Asus systems. This commit fixes this by allowing asus-wmi to load on systems without the Asus Management GUID. This is safe to do since all asus-wmi sub drivers use asus_wmi_register_driver which also checks for the GUID. This commit also improves the error messages in asus_wmi_register_driver to include "ASUS" in their description to make them more clear. This is important since we now rely on those errors when loaded on systems without the Asus Management GUID. Signed-off-by:

Recently introduced commit "platform/x86: intel_pmc_core: Show Latency Tolerance info <51337cd94d18184601ac0fb4cf1a02b8bbabc3d7> skipped the LTR from a reserved IP. Though this doesn't cause any functional issue but it is needed for the consumers of "ltr_ignore" as the index printing for "ltr_show" is missing. For example, w/o this change, a user that wants to ignore LTR from ME would do something like echo 5 > ltr_ignore but the index for ME is 6. Printing a reserved IP helps to properly calculate LTR ignore offsets. Cc: "David E. Box" <david.e.box@intel.com> Cc: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by:

A previous commit "platform/x86: intel_pmc_core: Make the driver PCH family agnostic <c977b98b>" provided better abstraction to this driver but has some fundamental issues. e.g. the following condition for (index = 0; index < pmcdev->map->ppfear_buckets && index < PPFEAR_MAX_NUM_ENTRIES; index++, iter++) is wrong because for CNL, PPFEAR_MAX_NUM_ENTRIES is hardcoded as 5 which is _wrong_ and even though ppfear_buckets is 8, the loop fails to read all eight registers needed for CNL PCH i.e. PPFEAR0 and PPFEAR1. This patch refactors the pfear show logic to correctly read PCH IP power gating status for Cannonlake and beyond. Cc: "David E. Box" <david.e.box@intel.com> Cc: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Fixes: c977b98b ("platform/x86: intel_pmc_core: Make the driver PCH family agnostic") Signed-off-by:

Only Coffeelake should use Cannonlake regmap other than Cannonlake platform. This allows Coffeelake special handling only when there is no matching PCI device and default reg map selected as per CPUID is for Sunrisepoint PCH. This change is needed to enable support for newer SoCs such as Icelake. Cc: "David E.

Commit c3b8e884 ("platform/x86: intel_int0002_vgpio: Implement irq_set_wake"), was written to fix some wakeup issues on Bay Trail (BYT) devices. We've received a bug report that this causes a suspend regression on some Cherry Trail (CHT) based devices. To fix the issues this causes on CHT devices, this commit modifies the irq_set_wake support so that we only implement irq_set_wake on BYT devices, Fixes: c3b8e884 ("platform/x86: intel_int0002_vgpio: ... irq_set_wake") Reported-and-tested-by:

There's a new wmi event generated by dell-wmi when pressing keyboard backlight hotkey: [ 3285.474172] dell_wmi: Unknown key with type 0x0010 and code 0x003f pressed This event is for notification purpose, let's ignore it. The keyboard backlight hotkey uses another event so it still works without event 0x3f. Signed-off-by:

The Point of View TAB-P1006W-232-3G tablet has an ACPI firmware node with a HID of BSG2150 describing the 2 Bosch sensors used in the device a BMC150 compatible accelerometer and a BMC150 compatible magnetometer. The ACPI firmware node actually contains 3 I2cSerialBusV2 resources, but this seems to be a copy and paste job from the BSG1160 firmware node on other devices, since there is no i2c-client listening to the 0x68 address listed in the third resource and the 0x68 address is identical to the address of the third resource in the BSG1160 nodes, where as the other 2 addresses are different. Add the ID to the I2C multi instantiate list, so that the i2c-multi-instantiate.c driver can handle it; And add the necessary info to the i2c-multi-instantiate.c driver to enumerate all I2C slaves correctly. To avoid triggering the: if (i < multi->num_clients) { dev_err(dev, "Error finding driver, idx %d\n", i); Error this commit lists the 3th device in the i2c_inst_data with a type of "bsg2150_dummy_dev".

Provide support for the fan capability registers for the next generation systems of types MQM87xx, MSN34xx, MSN37xx. These new registers provide configuration for tachometers and fan drawers connectivity. Use these registers for next generation led, fan and hotplug structures in order to distinguish between the systems which have minor configuration differences. This reduces the amount of code used to describe such systems. Signed-off-by:

Power button suspend for some Dell models was added in: commit 821b8536 ("platform/x86: intel-hid: Power button suspend on Dell Latitude 7275") by checking against the power button press notification (0xCE) to report the power button press event. The corresponding power button release notification (0xCF) was caught and ignored to stop it from being reported as an "unknown event" in the logs. The missing button release event is creating issues on Android-x86, as reported on the project mailing list for a Dell Latitude 5175 model, since the events are expected in down/up pairs. Report the power button release event to fix this issue. Link: https://groups.google.com/forum/#!topic/android-x86/aSwZK9Nf9RoTested-by:
