- clear_blocks_dcbz32_ppc will not work properly
- on PowerPC processors with a cache line size
- not equal to 32 bytes.
- Fortunately all processor used by Apple up to
- at least the 7450 (aka second generation G4)
- use 32 bytes cache line.
- This is due to the use of the 'dcbz' instruction.
- It simply clear to zero a single cache line,
- so you need to know the cache line size to use it !
- It's absurd, but it's fast...
-
- update 24/06/2003 : Apple released yesterday the G5,
- with a PPC970. cache line size : 128 bytes. Oups.
- The semantic of dcbz was changed, it always clear
- 32 bytes. so the function below will work, but will
- be slow. So I fixed check_dcbz_effect to use dcbzl,
- which is defined to clear a cache line (as dcbz before).
- So we still can distinguish, and use dcbz (32 bytes)
- or dcbzl (one cache line) as required.
-
