workqueue question

[Darran Hunt <dnh%snark.us@localhost>]

Hi,

I've been working on porting a driver for a crypto-acceleration card  
to NetBSD current (4.99.54), and I'm not quite sure that I understand  
workqueues in NetBSD.

Basically I've got an interrupt handler that fires when the requests  
on the card complete, and I want to schedule a job to run outside of  
the handler to deal with finishing the request.  The workqueue looks  
like an easy way to do this, but it only seems to allow one job to be  
scheduled.  To schedule more than one I'd have to manage a queue of  
work descriptors and hand one off per job - which makes the workqueue  
a lot less attractive as a solution.

Have I got that wrong?  Should I be able to queue multiple jobs  
without supplying each one with a unique work structure?

Or is there a more appropriate mechanism that I should be using instead?

Cheers,
Darran.
