If they're completely independent drivers that just happen to have the same value going into request_irq(), yes ... use SA_SHIRQ. Cores using ARC's stuff have EHCI (yes?), which is already a separate driver, so that would imply you should do so. More integrated silicion wouldn't work that way; it'd be more natural to have a single IRQ, dispatching to role-specific code as appropriate. - Dave ------------------------------------------------------- Using Tomcat but need to do more?
