    [ALSA] pcm-midlevel: Add more strict buffer position checks based on jiffies · bbf6ad13
    Jaroslav Kysela authored Apr 10, 2009
    
    
    Some drivers like Intel8x0 or Intel HDA are broken for some hardware variants.
    This patch adds more strict buffer position checks based on jiffies when
    internal hw_ptr is updated. Enable xrun_debug to see mangling of wrong
    positions.
    
    As a side effect, the hw_ptr interrupt update routine might do slightly better
    job when many interrupts are lost.
