The 970GX definition was added in 2007 and it made sense then but this version has never been released to the markets and it does not exist in the real world so there is no point in emulating it.

|
PowerPC core emulation status
|
|
|
|
INSN: instruction set.
|
|
OK => all instructions are emulated
|
|
KO => some insns are missing or some should be removed
|
|
? => unchecked
|
|
SPR: special purpose registers set
|
|
OK => all SPR registered (but some may be fake)
|
|
KO => some SPR are missing or should be removed
|
|
? => unchecked
|
|
MSR: MSR bits definitions
|
|
OK => all MSR bits properly defined
|
|
KO => MSR definition is incorrect
|
|
? => unchecked
|
|
IRQ: input signals definitions (mostly interrupts)
|
|
OK => input signals are properly defined
|
|
KO => input signals are not implemented (system emulation does not work)
|
|
? => input signals definitions may be incorrect
|
|
MMU: MMU model implementation
|
|
OK => MMU model is implemented and Linux is able to boot
|
|
KO => MMU model not implemented or bugged
|
|
? => MMU model not tested
|
|
EXCP: exceptions model implementation
|
|
OK => exception model is implemented and Linux is able to boot
|
|
KO => exception model not implemented or known to be buggy
|
|
? => exception model may be incorrect or is untested
