Hi,
I followed the documentation but failed to enable SGX NUMA:
https://qemu.readthedocs.io/en/latest/system/i386/sgx.html
Run:
# qemu-system-x86_64 -m 4G,maxmem=20G -smp sockets=2,cores=2
-cpu host,+sgx-provisionkey -object
memory-backend-ram,size=2G,host-nodes=0,policy=bind,id=node0 -object
memory-backend-epc,id=mem0,size=64M,prealloc=on,host-nodes=0,policy=bind
-numa node,nodeid=0,cpus=0-1,memdev=node0 -object
memory-backend-ram,size=2G,host-nodes=1,policy=bind,id=node1 -object
memory-backend-epc,id=mem1,size=28M,prealloc=on,host-nodes=1,policy=bind
-numa node,nodeid=1,cpus=2-3,memdev=node1 -M
sgx-epc.0.memdev=mem0,sgx-epc.0.node=0,sgx-epc.1.memdev=mem1,sgx-epc.1.node=1
qemu-system-x86_64: cannot bind memory to host NUMA nodes: Invalid argument
Is something wrong in the documentation or the code has been changed w/o update
the document? Thanks.
regards
Shawn
