Package: itop Version: 0.1-4 Followup-For: Bug #443798 I'm seeing the same behaviour on a (obviously quad-core) Intel Q9550 running Ubuntu. Also here on an Athlon64 X2 3800+.
It does indeed look like a case of very naive parsing of /proc/interrupts. itop -a output: INT NAME RATE MAX 0 [PIC-edge time] 0 Ints/s (max: 0) 1 [PIC-edge i804] 0 Ints/s (max: 0) 7 [ PIC-edge ] 0 Ints/s (max: 0) 8 [PIC-edge rtc0] 0 Ints/s (max: 0) 9 [PIC-fasteoi acpi] 0 Ints/s (max: 0) 14 [PIC-edge pata] 0 Ints/s (max: 0) 15 [PIC-edge pata] 0 Ints/s (max: 1) 19 [PIC-fasteoi fire] 0 Ints/s (max: 0) 20 [PIC-fasteoi sata] 0 Ints/s (max: 1) 21 [PIC-fasteoi eth0] 0 Ints/s (max: 1) 22 [PIC-fasteoi ehci] 0 Ints/s (max: 0) 23 [PIC-fasteoi ohci] 0 Ints/s (max: 0) 43 [MSI-edge rade] 1 Ints/s (max: 1) ^C The actual total interrupt rate is 40/sec (or 4000/sec when including LOC and SPU etc), and not 4 as reported above. :P /proc/interrupts contents: CPU0 CPU1 0: 87 28568 IO-APIC-edge timer 1: 58 14986 IO-APIC-edge i8042 7: 1 0 IO-APIC-edge 8: 1 50 IO-APIC-edge rtc0 9: 0 0 IO-APIC-fasteoi acpi 14: 0 0 IO-APIC-edge pata_amd 15: 241440 26512525 IO-APIC-edge pata_amd 19: 122 76686 IO-APIC-fasteoi firewire_ohci 20: 5774147 96634485 IO-APIC-fasteoi sata_nv 21: 314647 192677803 IO-APIC-fasteoi eth0 22: 6308 1192611 IO-APIC-fasteoi ehci_hcd:usb1, snd_hda_intel 23: 3644034 64562884 IO-APIC-fasteoi ohci_hcd:usb2, sata_nv 43: 51914 39311373 PCI-MSI-edge radeon NMI: 61220 63276 Non-maskable interrupts LOC: 2901076610 2755528381 Local timer interrupts SPU: 0 0 Spurious interrupts PMI: 61220 63276 Performance monitoring interrupts IWI: 0 0 IRQ work interrupts RES: 1593261302 1639629791 Rescheduling interrupts CAL: 20684 2163048 Function call interrupts TLB: 129984013 123515432 TLB shootdowns TRM: 0 0 Thermal event interrupts THR: 0 0 Threshold APIC interrupts MCE: 0 0 Machine check exceptions MCP: 16386 16386 Machine check polls ERR: 1 MIS: 0 It would not surprise me if #549404 was also due to the same mis-parsing bug. -- System Information: Debian Release: wheezy/sid APT prefers testing APT policy: (500, 'testing'), (500, 'stable'), (470, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.2.0-3-amd64 (SMP w/2 CPU cores) Locale: LANG=en_AU.UTF-8, LC_CTYPE=en_AU.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages itop depends on: ii libc6 2.13-35 itop recommends no packages. itop suggests no packages. -- no debconf information -MD -- ------------------------------------------------------------------------------- Michael Deegan Hugaholic http://www.deegan.id.au/ ------------------------- Jung, zr jbeel? ----------------------------------- -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
