What is the meaning of some Themis-specific OBP variables?
A29. Details can be found in the software manual for your particular Themis product. Some common variables: vme32-slave-base – the 32-bit VME base address of the Themis VME card. A read or write cycle to this VME address will cause the Themis card to respond as slave. A mapping between this VME address and a Solaris process’s address space can be established using sample program vme_dvma, which is included with the Themis VME nexus driver. This allows a VME master to effectively write to or read from the address space of a Solaris process. vme32-slave-size – the size, in bytes, of the address window starting at vme32-slave-base. vme32-master-base – the starting 32-bit address of a VME memory window that is mapped to a corresponding PCI address window on the Themis VME card. When the UltraSPARC CPU reads or writes to that PCI window, the cycle is propagated to the VME bus as a master cycle. A mapping between a Solaris process’s address space and this VME address can be established using
