eb0e90a8 - platform/surface: aggregator: Add dedicated bus and device type

Mon, 21 Dec 2020 18:39:56 +0000

platform/surface: aggregator: Add dedicated bus and device typeThe Surface Aggregator EC provides varying functionality, depending onthe Surface device. To manage this functionality, we use dedicatedclient devices for each subsystem or virtual device of the EC. Whilesome of these clients are described as standard devices in ACPI and thecorresponding client drivers can be implemented as platform drivers inthe kernel (making use of the controller API already present), manydevices, especially on newer Surface models, cannot be found there.To simplify management of these devices, we introduce a new bus andclient device type for the Surface Aggregator subsystem. The new devicetype takes care of managing the controller reference, essentiallyguaranteeing its validity for as long as the client device exists, thusalleviating the need to manually establish device links for that purposein the client driver (as has to be done with the platform devices).Signed-off-by: Maximilian Luz Reviewed-by: Hans de Goede Link: https://lore.kernel.org/r/20201221183959.1186143-7-luzmaximilian@gmail.comSigned-off-by: Hans de Goede List of files: /linux-6.15/drivers/platform/surface/aggregator/Makefile

0d21bb85 - platform/surface: aggregator: Add trace points

Mon, 21 Dec 2020 18:39:54 +0000

platform/surface: aggregator: Add trace pointsAdd trace points to the Surface Aggregator subsystem core. These tracepoints can be used to track packets, requests, and allocations. They arefurther intended for debugging and testing/validation, specifically incombination with the error injection capabilities introduced in thesubsequent commit.Signed-off-by: Maximilian Luz Reviewed-by: Hans de Goede Acked-by: Steven Rostedt (VMware) Link: https://lore.kernel.org/r/20201221183959.1186143-5-luzmaximilian@gmail.comSigned-off-by: Hans de Goede List of files: /linux-6.15/drivers/platform/surface/aggregator/Makefile

c167b9c7 - platform/surface: Add Surface Aggregator subsystem

Mon, 21 Dec 2020 18:39:51 +0000

platform/surface: Add Surface Aggregator subsystemAdd Surface System Aggregator Module core and Surface Serial Hub driver,required for the embedded controller found on Microsoft Surface devices.The Surface System Aggregator Module (SSAM, SAM or Surface Aggregator)is an embedded controller (EC) found on 4th and later generationMicrosoft Surface devices, with the exception of the Surface Go series.This EC provides various functionality, depending on the device inquestion. This can include battery status and thermal reporting (5th andlater generations), but also HID keyboard (6th+) and touchpad input(7th+) on Surface Laptop and Surface Book 3 series devices.This patch provides the basic necessities for communication with the SAMEC on 5th and later generation devices. On these devices, the ECprovides an interface that acts as serial device, called the SurfaceSerial Hub (SSH). 4th generation devices, on which the EC interface isprovided via an HID-over-I2C device, are not supported by this patch.Specifically, this patch adds a driver for the SSH device (device HIDMSHW0084 in ACPI), as well as a controller structure and associated API.This represents the functional core of the Surface Aggregator kernelsubsystem, introduced with this patch, and will be expanded upon insubsequent commits.The SSH driver acts as the main attachment point for this subsystem andsets-up and manages the controller structure. The controller in turnprovides a basic communication interface, allowing to send requests fromhost to EC and receiving the corresponding responses, as well asmanaging and receiving events, sent from EC to host. It is structuredinto multiple layers, with the top layer presenting the API used byother kernel drivers and the lower layers modeled after the serialprotocol used for communication.Said other drivers are then responsible for providing the (Surface modelspecific) functionality accessible through the EC (e.g. battery statusreporting, thermal information, ...) via said controller structure andAPI, and will be added in future commits.Signed-off-by: Maximilian Luz Link: https://lore.kernel.org/r/20201221183959.1186143-2-luzmaximilian@gmail.comSigned-off-by: Hans de Goede List of files: /linux-6.15/drivers/platform/surface/aggregator/Makefile
