If you are enabling the cache, you must perform a - global invalidate. If you are disabling the cache, you must - flush the cache contents first. This routine takes care of - doing these things. When first enabling the cache, make sure - you pass in the L2CR you want, as well as passing in the - global invalidate bit set. A global invalidate will only be - performed if the L2I bit is set in applyThis. When enabling - the cache, you should also set the L2E bit in applyThis. If - you want to modify the L2CR contents after the cache has been - enabled, the recommended procedure is to first call - __setL2CR(0) to disable the cache and then call it again with - the new values for L2CR. Examples: - - _setL2CR(0) - disables the cache - _setL2CR(0xB3A04000) - enables my G3 upgrade card: - - L2E set to turn on the cache - - L2SIZ set to 1MB - - L2CLK set to 1:1 - - L2RAM set to pipelined synchronous late-write - - L2I set to perform a global invalidation - - L2OH set to 0.5 nS - - L2DF set because this upgrade card - requires it - - A similar call should work for your card. You need to know - the correct setting for your card and then place them in the - fields I have outlined above. Other fields support optional - features, such as L2DO which caches only data, or L2TS which - causes cache pushes from the L1 cache to go to the L2 cache - instead of to main memory. - -IMPORTANT: - Starting with the 7450, the bits in this register have moved - or behave differently.
