    RISC-V: Show IPI stats · 8b20d2db
    Anup Patel authored
    This patch provides arch_show_interrupts() implementation to
    show IPI stats via /proc/interrupts.
    
    Now the contents of /proc/interrupts" will look like below:
               CPU0       CPU1       CPU2       CPU3
      8:         17          7          6         14  SiFive PLIC   8  virtio0
     10:         10         10          9         11  SiFive PLIC  10  ttyS0
    IPI0:       170        673        251         79  Rescheduling interrupts
    IPI1:         1         12         27          1  Function call interrupts
