The vme driver provides access to the VMEbus. On MVME141 boards, it operates the VMEbus part of the ofobio(4) device. On MVME147 boards, it operates the VMEchip ASIC connected to the PCCchip local bus controller. On MVME165 boards, it operates the VMEbus part of the lrc(4) local resource controller. On MVME162 and MVME172 boards, it operates the VMEchip2 ASIC connectod to the MCchip local bus controller. On MVME166, MVME167, MVME176 and MVME177 boards, it operates the VMEchip2 ASIC connected to the pcctwo(4) PCCchip2 local bus controller.

The vme driver exposes the D16 and D32 access spaces through the vmes and vmel drivers, respectively.

The currently supported VMEbus drivers are:

MVME376 AMD LANCE Ethernet device
MVME328, MVME328S and MVME328XT high performance SCSI controller
MVME327A SCSI and floppy controller
