hi all, I'm having a spot of problem trying to get the local/remote dram counters working on the NUMA sandybridge and ivybridge systems here.
Things work fine using intel-pcm, but those same counters don't work with hwpmc. Sandybridge - there's apparently an MSR that needs to be fiddled if the counters are active. Ivybridge - the v1 and v2 chips have different local/remote dram counters, and on my v2 setup there's actually /two/ LOCAL_DRAM: adrian@testbox1:~/git/github/erikarn/freebsd/sys/dev/hwpmc % pmccontrol -L | grep DRAM MEM_LOAD_UOPS_LLC_MISS_RETIRED.LOCAL_DRAM MEM_LOAD_UOPS_LLC_MISS_RETIRED.LOCAL_DRAM MEM_LOAD_UOPS_LLC_MISS_RETIRED.REMOTE_DRAM Now, i may be able to get to figuring this out at some point in the distant future, but I'd really appreciate any help I can get now. I'm now at the point with the NUMA affinity API stuff where I'm now chasing down when things are correctly working with local/remote RAM, and I'd really like to use hwpmc in sampling mode to work on it. Thanks for any help! -adrian _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
