Subject[PATCH 00/16] Convert WMI to a proper bus
From: "Darren Hart (VMware)" <>

This series is based on the original work of
Andy Lutomirski <> [1]. I have made minor edits, and in
one instance, squashed two patches in which the latter undid the former.

This series converts WMI [2] into a proper bus, adds some useful information via
sysfs, and exposes the embedded MOF [3] binary. It converts dell-wmi to use the
new WMI bus architecture.

This is the first part of an ongoing effort to enhance the WMI infrastructure
within the kernel, and eventually expose WMI to userspace for the consumption of
management utilities as it was intended.


Andy Lutomirski (15):
platform/x86: wmi: Drop "Mapper (un)loaded" messages
platform/x86: wmi: Pass the acpi_device through to parse_wdg
platform/x86: wmi: Clean up acpi_wmi_add
platform/x86: wmi: Track wmi devices per ACPI device
platform/x86: wmi: Turn WMI into a bus driver
platform/x86: wmi: Fix error handling when creating devices
platform/x86: wmi: Split devices into types and add basic sysfs attributes
platform/x86: wmi: Probe data objects for read and write capabilities
platform/x86: wmi: Instantiate all devices before adding them
platform/x86: wmi: Incorporate acpi_install_notify_handler
platform/x86: wmi: Add a new interface to read block data
platform/x86: wmi: Bind the platform device, not the ACPI node
platform/x86: wmi: Add an interface for subdrivers to access sibling devices
platform/x86: wmi-mof: New driver to expose embedded WMI MOF metadata
platform/x86: dell-wmi: Convert to the WMI bus infrastructure

Darren Hart (VMware) (1):
platform/x86: wmi: Require query for data blocks, rename writable to setable
