Author: Srikar Dronamraju <srikar@linux.vnet.ibm.com> # Date: Mon Aug 13 12:55:50 2018 +0530 # # powerpc/topology: Get topology for shared processors at boot # # On a shared lpar, Phyp will not update the cpu associativity at boot # time. Just after the boot system does recognize itself as a shared lpar and # trigger a request for correct cpu associativity. But by then the scheduler # would have already created/destroyed its sched domains. # # This causes: # - Broken load balance across Nodes causing islands of cores. # - Performance degradation esp if the system is lightly loaded # - dmesg to wrongly report all CPUs to be in Node 0. # - Messages in dmesg saying borken topology. # - With commit 051f3ca02e46 ("sched/topology: Introduce NUMA identity # node sched domain"), can cause rcu stalls at boot up. # # The sched_domains_numa_masks table which is used to generate cpumasks # is only created at boot time just before creating sched domains and # never updated. Hence, its better to get the topology correct before # the sched domains are created. # # For example on 64 core Power 8 shared lpar, dmesg reports: # # Brought up 512 CPUs # Node 0 CPUs: 0-511 # Node 1 CPUs: # Node 2 CPUs: # Node 3 CPUs: # Node 4 CPUs: # Node 5 CPUs: # Node 6 CPUs: # Node 7 CPUs: # Node 8 CPUs: # Node 9 CPUs: # Node 10 CPUs: # Node 11 CPUs: # ... # BUG: arch topology borken # the DIE domain not a subset of the NUMA domain # BUG: arch topology borken # the DIE domain not a subset of the NUMA domain # ... # # numactl/lscpu output will still be correct with cores spreading across # all nodes. # # Socket(s): 64 # NUMA node(s): 12 # Model: 2.0 (pvr 004d 0200) # Model name: POWER8 (architected), altivec supported # Hypervisor vendor: pHyp # Virtualization type: para # L1d cache: 64K # L1i cache: 32K # NUMA node0 CPU(s): 0-7,32-39,64-71,96-103,176-183,272-279,368-375,464-471 # NUMA node1 CPU(s): 8-15,40-47,72-79,104-111,184-191,280-287,376-383,472-479 # NUMA node2 CPU(s): 16-23,48-55,80-87,112-119,192-199,288-295,384-391,480-487 # NUMA node3 CPU(s): 24-31,56-63,88-95,120-127,200-207,296-303,392-399,488-495 # NUMA node4 CPU(s): 208-215,304-311,400-407,496-503 # NUMA node5 CPU(s): 168-175,264-271,360-367,456-463 # NUMA node6 CPU(s): 128-135,224-231,320-327,416-423 # NUMA node7 CPU(s): 136-143,232-239,328-335,424-431 # NUMA node8 CPU(s): 216-223,312-319,408-415,504-511 # NUMA node9 CPU(s): 144-151,240-247,336-343,432-439 # NUMA node10 CPU(s): 152-159,248-255,344-351,440-447 # NUMA node11 CPU(s): 160-167,256-263,352-359,448-455 # # Currently on this LPAR, the scheduler detects 2 levels of NUMA and # created NUMA sched domains for all CPUs, but it finds a single DIE # domain consisting of all CPUs.
