    [S390] irq: have detailed statistics for interrupt types · 052ff461
    Heiko Carstens authored
    Up to now /proc/interrupts only has statistics for external and i/o
    interrupts but doesn't split up them any further.
    This patch adds a line for every single interrupt source so that it
    is possible to easier tell what the machine is/was doing.
    Part of the output now looks like this;
    
               CPU0       CPU2       CPU4
    EXT:       3898       4232       2305
    I/O:        782        315        245
    CLK:       1029       1964        727   [EXT] Clock Comparator
    IPI:       2868       2267       1577   [EXT] Signal Processor
    TMR:          0          0          0   [EXT] CPU Timer
    TAL:          0          0          0   [EXT] Timing Alert
    PFL:          0          0          0   [EXT] Pseudo Page Fault
    [...]
