Hi
while debugging, I observed this:
1- a HardPf address is issued (0xbc000) in dcache
2- it is checked in L2
3- L2 misses
4- The block is inserted in L2.
So I want to know, why it doesn't go back to dcache?
1254053000: system.cpu.dcache-pf: Requesting a hw_pf to issue
1254053000: system.cpu.dcache-pf: returning 0xbc000
1254053000: system.l2: ReadReq bc000 miss
1254094000: system.l2: replacement: replacing 124000 with bc000: clean
1254094000: system.l2: blk bc000 inserted to cache
Why is it necessary for the prefetched data to be brought in to dcache?
May be the code has been written so that the data gets prefetched in to
the L2 cache.
