Bus fabric performance event select for PERFCTR2
| PERFSEL2 | Select an event for PERFCTR2. For each downstream port of the main crossbar, four events are available: ACCESS, an access took place; ACCESS_CONTESTED, an access took place that previously stalled due to contention from other masters; STALL_DOWNSTREAM, count cycles where any master stalled due to a stall on the downstream bus; STALL_UPSTREAM, count cycles where any master stalled for any reason, including contention from other masters. 0 (siob_proc1_stall_upstream): undefined 1 (siob_proc1_stall_downstream): undefined 2 (siob_proc1_access_contested): undefined 3 (siob_proc1_access): undefined 4 (siob_proc0_stall_upstream): undefined 5 (siob_proc0_stall_downstream): undefined 6 (siob_proc0_access_contested): undefined 7 (siob_proc0_access): undefined 8 (apb_stall_upstream): undefined 9 (apb_stall_downstream): undefined 10 (apb_access_contested): undefined 11 (apb_access): undefined 12 (fastperi_stall_upstream): undefined 13 (fastperi_stall_downstream): undefined 14 (fastperi_access_contested): undefined 15 (fastperi_access): undefined 16 (sram9_stall_upstream): undefined 17 (sram9_stall_downstream): undefined 18 (sram9_access_contested): undefined 19 (sram9_access): undefined 20 (sram8_stall_upstream): undefined 21 (sram8_stall_downstream): undefined 22 (sram8_access_contested): undefined 23 (sram8_access): undefined 24 (sram7_stall_upstream): undefined 25 (sram7_stall_downstream): undefined 26 (sram7_access_contested): undefined 27 (sram7_access): undefined 28 (sram6_stall_upstream): undefined 29 (sram6_stall_downstream): undefined 30 (sram6_access_contested): undefined 31 (sram6_access): undefined 32 (sram5_stall_upstream): undefined 33 (sram5_stall_downstream): undefined 34 (sram5_access_contested): undefined 35 (sram5_access): undefined 36 (sram4_stall_upstream): undefined 37 (sram4_stall_downstream): undefined 38 (sram4_access_contested): undefined 39 (sram4_access): undefined 40 (sram3_stall_upstream): undefined 41 (sram3_stall_downstream): undefined 42 (sram3_access_contested): undefined 43 (sram3_access): undefined 44 (sram2_stall_upstream): undefined 45 (sram2_stall_downstream): undefined 46 (sram2_access_contested): undefined 47 (sram2_access): undefined 48 (sram1_stall_upstream): undefined 49 (sram1_stall_downstream): undefined 50 (sram1_access_contested): undefined 51 (sram1_access): undefined 52 (sram0_stall_upstream): undefined 53 (sram0_stall_downstream): undefined 54 (sram0_access_contested): undefined 55 (sram0_access): undefined 56 (xip_main1_stall_upstream): undefined 57 (xip_main1_stall_downstream): undefined 58 (xip_main1_access_contested): undefined 59 (xip_main1_access): undefined 60 (xip_main0_stall_upstream): undefined 61 (xip_main0_stall_downstream): undefined 62 (xip_main0_access_contested): undefined 63 (xip_main0_access): undefined 64 (rom_stall_upstream): undefined 65 (rom_stall_downstream): undefined 66 (rom_access_contested): undefined 67 (rom_access): undefined |
