[Xen-devel] [PATCH] avoid injection of missed timer interrupts while debugging a guest

["Kamble, Nitin A" <nitin.a.kamble@xxxxxxxxx>]

Hi Keir, Ian,

Today if we stop the guest for debugging using the gdbserver and then continue with the guest execution the PIT finds that the time has gone ahead and it missed to inject so many timer ticks, and it tries to inject all of those one by one. So after the gdb continue command the guest just handles the timer interrupts for a long time before it can do anything else.

    This patch changes this PIT behavior, if it finds that the guest is being debugged then it does not try to inject missing timer ticks.

 

 Please apply or comment.

Thanks & Regards,

Nitin
