I have a question. I want to measure a number of Write Combined Transactions on my Core 2 Duo using VTune but I don't know what the name of this event.
I found in the VTune help that event BUS_TRANS_BURST counts the sum of all burst transactions such as: burst read, RFO, explicit writeback and Write Combined Transactions.
I.e. BUS_TRANS_BURST = Burst reads + RFOs + explicit writebacks + Write Combine Transactions.
I know that Burst reads in this formula are counted by BUS_TRANS_BRD, RFO are counted by BUS_TRANS_RFO, explicit writebacks are counted by BUS_TRANS_WB. But what event counts Write Combined Transactions?
I understand that Write Combine Transactions can be calculated as following: Write Combine Transactions = BUS_TRANS_BURST - (Burst reads + RFOs + explicit writebacks). But is there a particular event for Write Combined?
