when QEMU is started like:
qemu-system-x86_64 -smp 2 -machine hmat=on \
-m 2G \
-object memory-backend-ram,size=1G,id=m0 \
-object memory-backend-ram,size=1G,id=m1 \
-numa node,nodeid=0,memdev=m0 \
-numa node,nodeid=1,memdev=m1,initiator=0 \
-numa cpu,node-id=0,socket-id=0 \
-numa cpu,node-id=0,socket-id=1 \
-numa hmat-lb,initiator=0,target=0,hierarchy=memory,data-type=access-latency,latency=5 \
-numa hmat-lb,initiator=0,target=0,hierarchy=memory,data-type=access-bandwidth,bandwidth=200M \
-numa hmat-lb,initiator=0,target=1,hierarchy=memory,data-type=access-latency,latency=10 \
-numa hmat-lb,initiator=0,target=1,hierarchy=memory,data-type=access-bandwidth,bandwidth=100M \
-numa hmat-cache,node-id=0,size=8K,level=1,associativity=direct,policy=write-back,line=5 \
-numa hmat-cache,node-id=0,size=16K,level=2,associativity=direct,policy=write-back,line=5
it errors out with:
-numa hmat-cache,node-id=0,size=16K,level=2,associativity=direct,policy=write-back,line=5:
Invalid size=16384, the size of level=2 should be less than the size(8192) of level=1
which doesn't look right as one would expect that L1 < L2 < L3 ...
Fix it by sawpping relevant size checks.
