Multiplexing of Northbridge events does not work with the current 2.6.30
code base. I was suggesting
you keep using system-wide but instead use two separate runs.
pfmon --with-header --outfile=test1 --pin-command -u
-eDRAM_ACCESSES_PAGE:HIT,DRAM_ACCESSES_PAGE:MISS,DRAM_ACCESSES_PAGE:CONFLICT,DRAM_ACCESSES_PAGE:ALL
$PASEC_COMMAND
pfmon --with-header --outfile=test2 --pin-command -u
-eDRAM_ACCESSES_PAGE:DCT1_PAGE_HIT,DRAM_ACCESSES_PAGE:DCT1_PAGE_MISS,DRAM_ACCESSES_PAGE:DCT1_PAGE_CONFLICT,DRAM_ACCESSES_PAGE:ALL
$PASEC_COMMAND
