Polling of i/o devices on host initiated communication transports

A computer readable storage medium to store kernel driver instructions, which when executed by a processor, cause the processor to:

• detect a read request, from an application program, to read data from an input/output (I/O) device;
• maintain an interrupt pipe between the data processing system and the I/O device in a disabled state;
• issue a start command responsive to detecting a sideband interrupt indicating that read data associated with the read request is available;
• and
• enable the interrupt pipe and poll the I/O device for the data responsive to the start command.

A computing platform, comprising:

• a processor;
• a computer readable storage medium, accessible to the processor, to store kernel driver instructions, which when executed by the processor cause the processor to perform operations comprising:
• detecting a read request, initiated by an application program, to read data from an input/output (I/O) device, wherein the I/O device comprises a touchpad;
• pending the read request and maintaining an interrupt pipe between the data processing system and the I/O device in a disabled state;
• responsive to detecting a sideband interrupt indicating that read data associated with the read request is available, issuing a start command;
• and
• responsive to the start command, enabling the interrupt pipe and polling the I/O device for the data;
• a touchscreen;
• and
• a touchscreen controller to communicate touchscreen data to the processor, wherein the touchscreen data is indicative of a touchscreen coordinate in proximity to a touchscreen contact point by a user.
