Hello All, I am sure that the TDM bus driver model/framework will make us put a lot more programming effort without any assurance of the code being accepted by the Linux community, especially as there are many Telephony/VoIP stack implementations in Linux such as the Sangoma WANPIPE Kernel suite which have their own Zaptel TDM (channelized zero-copy) interface layer. There are other High Speed serial (HSS) API interfaces, again supporting channelized and/or prioritized API interfaces. All these implementations are proprietary and have their own tightly coupled upper layers and hardware abstraction layers. It is difficult to predict that these stacks will move towards a generic TDM bus driver interface. Therefore, i think we can have our own tightly coupled interface with our VoIP framework and let us the keep the driver as it is, i.e., as a misc driver.

I'm wondering if we need a TDM framework in the kernel. I guess if Poonam could possibly describe how this driver is actually used that would be helpful. I see we have 8315 with a discrete TDM block and I'm guessing 82xx/85xx based CPM parts of some form of TDM as well. - k -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
