Each slot 78 is numbered and virtual slot numbers are assigned to the internal 79 devices. Using a pci_dev as other busses do does not really make 80 sense in the MCA context as the MCA bus resources require card 81 specific interpretation. 82 </para> 83 <para> 84 Finally the MCA bus functions provide a parallel set of DMA 85 functions mimicing the ISA bus DMA functions as closely as possible, 86 although also supporting the additional DMA functionality on the 87 MCA bus controllers. 88 </para> 89 </chapter> 90 <chapter id="bugs"> 91 <title>Known Bugs And Assumptions</title> 92 <para> 93 None. 94 </para> 95 </chapter> 96 97 <chapter id="pubfunctions"> 98 <title>Public Functions Provided</title> 99 !Edrivers/mca/mca-legacy.c 100 </chapter> 101 102 <chapter id="dmafunctions"> 103 <title>DMA Functions Provided</title> 104 !Iarch/x86/include/asm/mca_dma.h 105 </chapter> 106 107 </book>
