The SPB Framework Extension is a KMDF extension library.

WHAT DOES SPB MEAN DRIVERS

The SPB framework simplifies development of an SPB controller driver and improves the compatibility between peripheral drivers and the controller driver by providing common implementation of the "top-half" of the driver that processes I/O requests (as compared to the "bottom-half", which is driven by the top-half and controls the hardware).

WHAT DOES SPB MEAN WINDOWS

The SPB framework extension library extends the Windows Driver Framework to support SPB drivers. Some of those devices may make more sense over buses like USB rather than I☬. Modern SoCs with on-SoC sensor low power cores can implement non-I☬ solutions as needed.ĭevices on removable docks/ports should also follow the guidance around docking scenarios, also included in the WEG. I☬ is available on CS and S3 traditional power model. There are a number of device scenarios that leverage SPB for connectivity. Please contact your platform provider for drivers and support. Microsoft supports SPB on platforms running in both Connected Standby (CS) and S3 configurations. Microsoft supports SPB on ARM systems and x86/圆4 platforms (running in S3 configurations). The Windows Hardware Compatibility Program does not contain any requirements specific to SPI bus. Simple Peripheral Interface (SPI): Support for SPI is optional and up to the SoC partner. Use the Windows Hardware Lab Kit (HLK) to test devices against those requirements. Microsoft provides Windows Hardware Compatibility Program requirements for I☬. Inter Integrated Circuit (I☬): I☬ is the primary bus that is validated as part of SPB and is highly recommended on SoC systems.

WHAT DOES SPB MEAN WINDOWS 8

Windows provides support for the SPB Class Extension (spbcx.sys) in Windows 8 and beyond. Most peripherals support device signaling through a separate interrupt (often GPIO based) mechanism, and accurately mapped in ACPI. There is no in-band interrupt support for SPB. System manufacturers must ensure accurate information in ACPI to enumerate the SPB-connected peripheral devices for the Plug and Play manager, and specifies the hardware resources that are dedicated to each device. Peripheral devices typically have fixed connections to an SPB and cannot be removed. The following are some generic considerations for SPB:

WHAT DOES SPB MEAN SERIAL

Yes, using Serial Framework extension (SerCx2)Ĭustom transfer modes supported with SerCx2 Yes, using Windows Driver Foundation (WDF) Master only, "General Call" is not supported The following table summarizes the support for the Simple Peripheral Bus. Windows uses ACPI as the primary means for device identification, configuration, and control. The Windows infrastructure supports devices that share buses, buses that are multiplexed on the same line, and device configuration through ACPI. With the aid of the KMDF platform, the controller driver is used predominantly to define the hardware-specific interfaces necessary to enable controller function. In Windows, buses are supported through KMDF controller drivers. The complete device definition is defined through Advanced Configuration and Power Interface (ACPI). The architecture provides flexible device configuration topologies supporting simultaneous use of buses for control and data transactions, as well as GPIO for signaling and interrupts. Chipset vendors, OEMs, or IHVs must develop a controller driver implemented in KMDF. Controller drivers are not provided in-box. This topic covers recommendations for Simple Peripheral Bus in Windows 10.Windows includes support for low-power, simple buses, such as Inter Integrated Circuit (I☬) and (I☬) and Simple Peripheral Interface (SPI), using framework extensions of the Kernel Mode Driver Framework (KMDF) architecture.
