On pseries, memory_add_physaddr_to_nid() finds an # appropriate nid for a given address by looking up the LMB containing the # address and then passing that LMB to of_drconf_to_nid_single() to get the # nid. In dlpar_add_lmb() we get this address from the LMB itself. # # In short, we have a pointer to an LMB and then we are searching for # that LMB *again* in order to find its nid. # # If we call of_drconf_to_nid_single() directly from dlpar_add_lmb() we # can skip the redundant lookup. The only error handling we need to # duplicate from memory_add_physaddr_to_nid() is the fallback to the # default nid when drconf_to_nid_single() returns -1 (NUMA_NO_NODE) or # an invalid nid. # # Skipping the extra lookup makes hot-add operations faster, especially # on machines with many LMBs. # # Consider an LPAR with 126976 LMBs. In one test, hot-adding 126000 # LMBs on an upatched kernel took ~3.5 hours while a patched kernel # completed the same operation in ~2 hours: # # Unpatched (12450 seconds): # Sep 9 04:06:31 ltc-brazos1 drmgr[810169]: drmgr: -c mem -a -q 126000 # Sep 9 04:06:31 ltc-brazos1 kernel: pseries-hotplug-mem: Attempting to hot-add 126000 LMB(s) # [...] # Sep 9 07:34:01 ltc-brazos1 kernel: pseries-hotplug-mem: Memory at 20000000 (drc index 80000002) was hot-added # # Patched (7065 seconds): # Sep 8 21:49:57 ltc-brazos1 drmgr[877703]: drmgr: -c mem -a -q 126000 # Sep 8 21:49:57 ltc-brazos1 kernel: pseries-hotplug-mem: Attempting to hot-add 126000 LMB(s) # [...] # Sep 8 23:27:42 ltc-brazos1 kernel: pseries-hotplug-mem: Memory at 20000000 (drc index 80000002) was hot-added # # It should be noted that the speedup grows more substantial when # hot-adding LMBs at the end of the drconf range. This is because we # are skipping a linear LMB search. # # To see the distinction, consider smaller hot-add test on the same # LPAR. A perf-stat run with 10 iterations showed that hot-adding 4096 # LMBs completed less than 1 second faster on a patched kernel: # # Unpatched: # Performance counter stats for 'drmgr -c mem -a -q 4096' (10 runs): # # 104,753.42 msec task-clock # 0.992 CPUs utilized ( +- 0.55% ) # 4,708 context-switches # 0.045 K/sec ( +- 0.69% ) # 2,444 cpu-migrations # 0.023 K/sec ( +- 1.25% ) # 394 page-faults # 0.004 K/sec ( +- 0.22% ) # 445,902,503,057 cycles # 4.257 GHz ( +- 0.55% ) (66.67%) # 8,558,376,740 stalled-cycles-frontend # 1.92% frontend cycles idle ( +- 0.88% ) (49.99%) # 300,346,181,651 stalled-cycles-backend # 67.36% backend cycles idle ( +- 0.76% ) (50.01%) # 258,091,488,691 instructions # 0.58 insn per cycle # # 1.16 stalled cycles per insn ( +- 0.22% ) (66.67%) # 70,568,169,256 branches # 673.660 M/sec ( +- 0.17% ) (50.01%) # 3,100,725,426 branch-misses # 4.39% of all branches ( +- 0.20% ) (49.99%) # # 105.583 +- 0.589 seconds time elapsed ( +- 0.56% ) # # Patched: # Performance counter stats for 'drmgr -c mem -a -q 4096' (10 runs): # # 104,055.69 msec task-clock # 0.993 CPUs utilized ( +- 0.32% ) # 4,606 context-switches # 0.044 K/sec ( +- 0.20% ) # 2,463 cpu-migrations # 0.024 K/sec ( +- 0.93% ) # 394 page-faults # 0.004 K/sec ( +- 0.25% ) # 442,951,129,921 cycles # 4.257 GHz ( +- 0.32% ) (66.66%) # 8,710,413,329 stalled-cycles-frontend # 1.97% frontend cycles idle ( +- 0.47% ) (50.06%) # 299,656,905,836 stalled-cycles-backend # 67.65% backend cycles idle ( +- 0.39% ) (50.02%) # 252,731,168,193 instructions # 0.57 insn per cycle # # 1.19 stalled cycles per insn ( +- 0.20% ) (66.66%) # 68,902,851,121 branches # 662.173 M/sec ( +- 0.13% ) (49.94%) # 3,100,242,882 branch-misses # 4.50% of all branches ( +- 0.15% ) (49.98%) # # 104.829 +- 0.325 seconds time elapsed ( +- 0.31% ) # # This is consistent.
