>From my point of view, SA_SHIRQ should be ok for the 3 modules. Modules IRQ handler can get the current OTG controller mode.
For example, in Host IRQ handler, it will get the mode. If the mode is Host, the handler should deal with the Host mode IRQ event. If the mode is Device, the handler should return IRQ_NONE and let the UDC module IRQ handler to deal with the IRQ event. And the IRQ handler can read the IRQ status to determine the interrupt source.

If SA_SHIRQ is used, isn't it the responsibility of ISR to mask the interrupts at the starting, service the received interrupt and unmask the interrupts before returning? Or were you using SA_SHIRQ | SA_INTERRUPT? If that is the case, Linux would do the masking, rt? -suj On 27/04/06, Li Yang-r58472 <[EMAIL PROTECTED]> wrote: > Actually we had done a driver for ARC OTG controller, which is still not very stable.
