[Question] How do you access metadata about the Cache from a prefetcher function? about scarab HOT 2 CLOSED

To answer these kind of questions, I suggest searching the source code for examples of how that is done elsewhere in the code. For example, to find some use cases of getting cache instances, I simply searched for Cache (case sensitive, whole word) and found a few matching lines:

Cache* l1_cache = &mem->uncores[ic->proc_id].l1->cache;

Cache* dcache = &(cmp_model.dcache_stage[proc_id].dcache)

Icache_Stage* ic = &(cmp_model.icache_stage[proc_id]);
Cache* icache = &(ic->icache);

For your specific question of getting cache configuration params, it's probably easier to just read the global parameters. For example: DCACHE_SIZE, DCACHE_ASSOC, DCACHE_LINE_SIZE for Dcache.
