Hi Steve,
Since a few weeks I'm working with the sampler object. For some test I
would like to do, I need to keep the caches warm while fast forwarding.
I thought this could simply be realized by creating a single data and
instruction cache (level 1) and pointing the SimpleCPU and DetailedCPU
to the same caches. I thought this would not form a major problem
because the two cpu's are never active at the same time. Unfortunately
this idea was too naive and I got the message:
warn: Entering event queue. Starting simulation...
0: Event_8a1c8a0: New switch event curTick=0 when=10000
m5.debug: m5/mem/cache/tags/cache_tags_impl.hh:336: typename
CacheTags<Tags, Compression>::BlkType* CacheTags<Tags,
Compression>::handleFill(typename Tags::BlkType*, MSHR*, unsigned int,
MemReqList&) [with Tags = LRU, Compression = NullCompression]:
Assertion `target->offset + target->size <= blkSize' failed.
Program aborted at cycle 127
Geannuleerd (core dumped)
I would like to fix the problem, but I don't know were to start. Do you
have an idea what the problem might be? Do you see a quick and easy
solution?
Configuration file:
root = Root()
root.hier = HierParams(do_data=True, do_events=True)
root.icache = L1Cache(out_bus=Parent.toL2Bus)
root.dcache = L1Cache(out_bus=Parent.toL2Bus)
root.toL2Bus = ToL2Bus()
root.l2 = L2(in_bus=Parent.toL2Bus, out_bus=Parent.toMemBus)
root.toMemBus = Bus(width=16, clock=1*Parent.clock.period)
root.dram = BaseMemory(in_bus=Parent.toMemBus,
latency=100*Parent.clock.period,
uncacheable_latency=1000*Parent.clock.period)
root.Last1 = Benchmarks.Crafty()
root.cpu = [ SimpleCPU( icache = Parent.icache, dcache = Parent.dcache,
width = 1), DetailedCPU( icache = Parent.icache, dcache =
Parent.dcache) ]
root.cpu[0].workload = Parent.Last1
root.cpu[1].workload = Parent.Last1
phase0_cpus = [ root.cpu[0] ]
phase1_cpus = [ root.cpu[1] ]
root.sampler = [ Sampler(periods = [1e4, 1e3], phase0_cpus=phase0_cpus,
phase1_cpus = phase1_cpus ) ]
BaseCPU.max_insts_any_thread = 1e7
