Host Bus Adapter (HBA) drivers

Host Bus Adapter (HBA) drivers

A Host Bus Adapter (HBA) driver handles the low-level details of programming a hardware controller to act upon commands issued by target drivers, and responds to interrupts generated by the commands sent to the controller. HBA interaction with the controller includes input and output of data to the registers, and the transfer of data through either DMA or programmed I/O. See ``DMA'' and ``Programmed I/O (PIO)''.

Detailed information about developing HBA drivers will be provided in a future release of the HDK.
