Raw Normal View History

Update the hwpmc driver to have the new type HASWELL_XEON. Also go back through HASWELL, IVY_BRIDGE, IVY_BRIDGE_XEON and SANDY_BRIDGE to straighten out all the missing PMCs. We also add a new pmc tool pmcstudy, this allows one to run the various formulas from the documents "Using Intel Vtune Amplifier XE on XXX Generation platforms" for IB/SB and Haswell. The tool also allows one to postulate your own formulas with any of the various PMC's. At some point I will enahance this to work with Brendan Gregg's flame-graphs so we can flamegraph various PMC interactions. Note the manual page also needs some work (lots of work) but gnn has committed to help me with that ;-) Reviewed by: gnn MFC after:1 month Sponsored by: Netflix Inc.

Update the hwpmc driver to have the new type HASWELL_XEON. Also go back through HASWELL, IVY_BRIDGE, IVY_BRIDGE_XEON and SANDY_BRIDGE to straighten out all the missing PMCs. We also add a new pmc tool pmcstudy, this allows one to run the various formulas from the documents "Using Intel Vtune Amplifier XE on XXX Generation platforms" for IB/SB and Haswell. The tool also allows one to postulate your own formulas with any of the various PMC's. At some point I will enahance this to work with Brendan Gregg's flame-graphs so we can flamegraph various PMC interactions. Note the manual page also needs some work (lots of work) but gnn has committed to help me with that ;-) Reviewed by: gnn MFC after:1 month Sponsored by: Netflix Inc.

Update the hwpmc driver to have the new type HASWELL_XEON. Also go back through HASWELL, IVY_BRIDGE, IVY_BRIDGE_XEON and SANDY_BRIDGE to straighten out all the missing PMCs. We also add a new pmc tool pmcstudy, this allows one to run the various formulas from the documents "Using Intel Vtune Amplifier XE on XXX Generation platforms" for IB/SB and Haswell. The tool also allows one to postulate your own formulas with any of the various PMC's. At some point I will enahance this to work with Brendan Gregg's flame-graphs so we can flamegraph various PMC interactions.

Update the manual page to be a bit more sane. It still may need some work, but at least now it will read properly. (gnn you are still on the hook to help out with this like you committed). Sponsored by: Netflix.
