What is a "Software Interrupt"?

["Thippeswamy, Aravind" <AravindT@xxxxxxx>]

Hi,

        What is a “Software Interrupt”? I was going thru the LDD 3 and stumbled upon this. There is an

instance while explaining spin_lock_bh() function that the author

mentions that this only disables the "Software Interrupts"( LDD 3,page

number 119). In the immediately next paragraph, these "Software

Interrupts" are linked to "tasklets". I am not able to fully understand

this point. It would be really nice if some one elaborated on this.

 

 

 

Regards,,

Aravind.
