void ICFreeze ( void );

None.

Return Values

None.

Description

Locks the current contents of the L1 instruction cache so they cannot be invalidated. Hits are still serviced but misses go straight to the L2 instruction cache or 60x bus.

In PowerPC architecture jargon, this feature is referred to as locking the instruction cache. We use the word "freeze" for the Wii to distinguish between the locked cache and DMA features.
