platform/x86: wmi: add WMI support to MODULE_DEVICE_TABLE()

2019-03-07T16:46:29Z

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: Pali Rohár Signed-off-by: Mattias Jacobsson <2pi@mok.nu> Acked-by: Masahiro Yamada Signed-off-by: Darren Hart (VMware)

platform/x86: wmi: move struct wmi_device_id to mod_devicetable.h

2019-03-07T16:46:07Z

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.

modpost: file2alias: define size of alias

2019-03-07T07:12:34Z

The size of the variable alias provided to do_entry functions are currently not readily available. Thus hindering do_entry functions to perform bounds checking. Define the macro ALIAS_SIZE containing the size of the variable alias. Signed-off-by: Mattias Jacobsson <2pi@mok.nu> Acked-by: Masahiro Yamada Signed-off-by: Darren Hart (VMware)

tee: add bus driver framework for TEE based devices

2019-02-01T14:12:46Z

Introduce a generic TEE bus driver concept for TEE based kernel drivers which would like to communicate with TEE based devices/services. Also add support in module device table for these new TEE based devices. In this TEE bus concept, devices/services are identified via Universally Unique Identifier (UUID) and drivers register a table of device UUIDs which they can support. So this TEE bus framework registers following apis: - match(): Iterates over the driver UUID table to find a corresponding match for device UUID. If a match is found, then this particular device is probed via corresponding probe api registered by the driver. This process happens whenever a device or a driver is registered with TEE bus. - uevent(): Notifies user-space (udev) whenever a new device is registered on this bus for auto-loading of modularized drivers. Also this framework allows for device enumeration to be specific to corresponding TEE implementation like OP-TEE etc. Signed-off-by: Sumit Garg Reviewed-by: Daniel Thompson Reviewed-by: Bhupesh Sharma Signed-off-by: Jens Wiklander

modpost: file2alias: go back to simple devtable lookup

2018-12-01T13:21:57Z

Commit e49ce14150c6 ("modpost: use linker section to generate table.") was not so cool as we had expected first; it ended up with ugly section hacks when commit dd2a3acaecd7 ("mod/file2alias: make modpost compile on darwin again") came in. Given a certain degree of unknowledge about the link stage of host programs, I really want to see simple, stupid table lookup so that this works in the same way regardless of the underlying executable format.

modpost: Create macro to avoid variable shadowing

2018-10-28T15:41:41Z

Create DEF_FIELD_ADDR_VAR as a more generic version of the DEF_FIELD_ADD macro, allowing usage of a variable name other than the struct element name. Also, sets DEF_FIELD_ADDR as a specific usage of DEF_FILD_ADDR_VAR in which the var name is the same as the struct element name. Then, makes use of DEF_FIELD_ADDR_VAR to create a variable of another name, in order to avoid variable shadowing. Signed-off-by: Leonardo Bras Signed-off-by: Masahiro Yamada

modpost: remove leftover symbol prefix handling for module device table

2018-10-19T00:47:44Z

Blackfin and metag were the only architectures that prefix symbols with an underscore. They were removed by commit 4ba66a976072 ("arch: remove blackfin port"), commit bb6fb6dfcc17 ("metag: Remove arch/metag/"), respectively. It is no longer necessary to handle part of module device table symbols. Signed-off-by: Masahiro Yamada
