| <title>Introduction</title> |
| <para> |
| The MCA bus functions provide a generalised interface to find MCA |
| bus cards, to claim them for a driver, and to read and manipulate POS |
| registers without being aware of the motherboard internals or |
| certain deep magic specific to onboard devices. |
| </para> |
| <para> |
| The basic interface to the MCA bus devices is the slot. Each slot |
| is numbered and virtual slot numbers are assigned to the internal |
| devices. Using a pci_dev as other busses do does not really make |
| sense in the MCA context as the MCA bus resources require card |
| specific interpretation. |
| </para> |
| <para> |
| Finally the MCA bus functions provide a parallel set of DMA |
| functions mimicing the ISA bus DMA functions as closely as possible, |
| although also supporting the additional DMA functionality on the |
| MCA bus controllers. |
