What are the differences between processors having different PVRs?

Hi,all

I want to konw the differences between processors having different PVRs.I kown PVR values contain information on both the cpu model(upper 16 bits) and on the precise revision(low 16 bits).But I want to know the exact attributes that may affect software.Like e500v2,for example.I want to emulate a e500v2 core using QEMU,the exact PVR is 0x80212051 and the QEMU doesn't support.I want to kown the attributes of the 0x80212051 to make some changes.Anyone can help me?Thank you.

I don't think we have a public document describing differences between revisions of a core. However, I do not think the differences would be relevant to QEMU -- usually they are bug fixes or things which are not software-visible. You could add it as a new PVR (CPU_POWERPC_e500v2_v51_dp would be an appropriate name) but no behavioral differences.
