"generic_ti" is more like 232 and "ipi 76" is more = like 111. The others at the right are normally blank (other than total). Lots of bcm283x_dw interrupts if around 24k is correct. As the numbers = do not change scale when the systat refresh interval is explicitly = scaled, I assume that the figures are per second (or per some other time = unit, possibly just for the most recent unit instead of mean). I'm not sure it will be readable but the below is a capture of a systat = -vmstat display. > 2 users Load 0.01 0.02 0.00 Dec 26 20:33 >=20 > Mem:KB REAL VIRTUAL VN PAGER = SWAP PAGER > Tot Share Tot Share Free in out = in out > Act 29944 6384 199516 7404 27876 count > All 34164 8100 225364 26156 pages =20 > Proc: = Interrupts > r p d s w Csw Trp Sys Int Sof Flt ioflt 24461 = total > 23 502 6 36 24k 100 cow = mbox0 1 > zfod = vchiq0 2 > 0.1%Sys 0.0%Intr 0.0%User 0.0%Nice 99.8%Idle ozfod 24118 = bcm283x_dw > | | | | | | | | | | %ozfod = bcm_dma0 > daefr = uart0 65 > 8 dtbuf prcfr = sdhci_bcm0 > Namei Name-cache Dir-cache 64790 desvn totfr 232 = generic_ti > Calls hits % hits % 64150 numvn react 111 = ipi 76 > 3 3 100 38416 frevn pdwak > 1 pdpgs > Disks mmcsd md0 da0 intrn > KB/t 0.00 0.00 0.00 195896 wire > tps 0 0 0 2620 act > MB/s 0.00 0.00 0.00 711648 inact > %busy 0 0 0 cache > 27876 free > 88292 buf =3D=3D=3D Mark Millard markmi at dsl-only.net
