I am attempting to port the Broadcom tg3 NetXtreme linux driver to rtnet. The Broadcom driver internally utilizes spin_lock_bh/spin_unlock_bh to disable/enable software interrupts. There is no rtdm lock equivalent. I believe that software interrupts are used by the driver for the following reasons: 1. To allow for simultaneous DMA read write operations 2. To use shared local variables in a critical section of the driver. 3. To receive changes to settings variables in realtime from the userpace Nextreme utilities. (not sure about this one).
What RTDM lock functions should I use to substitute for spin_lock_bh/spin_unlock_bh? Should I substitute rtdm_lock_get_irqsave/rtdm_lock_put_irqrestore? Or does rtdm need to ne extended for softirqs used internally by the driver? I looked through the other device drivers and could not detect the correct substitute. RSVP. Thanks.

Does it make network security easier or more difficult to achieve? Read this whitepaper to separate the two and get a better understanding. http://p.sf.net/sfu/hp-phase2-d2d _______________________________________________ RTnet-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/rtnet-developers
