Hi,
Can anybody confirm what the default cache setup is supposed to for the 603/604 with respect to the chip ram area?
I discovered recently (quite by accident whilst talking to Patrik about screwy performance results) that on my system it seems to be cached (copyback too), rather than non-cacheable. For writes, this slowed it down a *lot*. Allocating chip memory with AllocVecPPC() using MEMF_WRITETRHOUGH or MEMF_CACHEOFF corrected this.
This seems odd to me as I cannot think of any reason why the chip ram should be copyback enabled.
Is my installation screwy?
