Steve, you make it sound like very many different PowerPC chips: You said you did the Power 4, Power 5 , Power 6 and now Power 7 routines. And there are the 970 and the Cell. While this sounds like 7 different PPC chips. But aren't this actually only 2 main families? Wouldn't it be possible to create two main routine to cover all? One type that performs good on the family of Power4/5 and 7. And one that performs good on the family of P6 and Cell? How are the Linux hackers handling this? Maybe there is room for consolidating?
