The times are with respect to the time stamp taken at the beginning of
handle_irq(). 2.7us is to the start of serial8250_interrupt(), 4.5us is to
the start of serial8250_handle_irq() and so on.
arch/x86/kernel/irq_32.c handle_irq() 0us
drivers/tty/serial/8250/8250.c serial8250_interrupt() 2.7us
drivers/tty/serial/8250/8250.c serial8250_handle_irq() 4.5us
drivers/tty/serial/8250/8250.c serial8250_modem_status() 7.4us
drivers/tty/serial/serial_core.c uart_handle_dcd_change() 7.8us
include/linux/pps_kernel.h inline pps_get_ts()
What processor and what speed is this being run on, please? I'm trying
to get a handle on whether this is a recent PC, an Intel Atom, or an old
mobile phone! (OK, I do see the X86!).
