Does anyone have a pointer for a MOST (Media Oriented Systems Transport) driver?
http://en.wikipedia.org/wiki/Media_Oriented_Systems_Transport
I have seen announcements of Linux systems that support MOST:
http://linuxdevices.com/news/NS2586090082.html
But I have not seen the driver architecture, or the protocol that people are running on them...
Any pointers?

Many - all automotive embedded - If you drive a recent car - from Audi, Aston Martin, Ford, BMW, Honda, Hyundai/Kia, DaimlerChrysler, Jaguar, Land Rover, Nissan, Porsche, Toyota, Volvo, or VW - you may be using it today. > Specifically, any applications worth caring about? Again - depends on who you are. If you are one of the above - yes, you care allot. If you are a enthusiast you wants low level access to entertainment system in your car - then you care too. It is like asking if I should care about applications using 100Base-T - as a user - I just want it to work and I only care when it doesn't work; as a driver developer - I care alot, but am agnostic to the application. I found a spec that says MOST runs IP - http://www.mostcooperation.com/downloads/Specifications/MOST%20Specifications/MAMAC%20Specification but thought I would ask if anyone else has any public work about the non-IP protocols. For those that might care, full spec is at: http://www.mostcooperation.com/downloads/Specifications/MOST%20Specifications/MOSTSpecification.pdf -Robin ^ permalink raw reply [flat|nested] 12+ messages in thread

Quite interesting that you found it. It was released yesterday, and I wanted to write an announcement in a few days, at least at the Xenomai lists. Anyway ... > This might be what you are looking for: > > http://most4linux.sourceforge.net/ Yes, that's a MOST driver for a OS 8604 PCI interface that I wrote as Diploma Thesis at Siemens. It was relased as OpenSource just now. It only supports synchronous data transfer. The Most NetServices are in userspace. There's a OpenSource demonstration available, but no full NetServices implementation. You can buy a license from SMC or use the specification to re-write an OSS implementation. However, that's all userspace, so no GPL problem here. :) I must say that it was more a demonstration how a Linux driver could be ported to real-time Linux extension than a real productive working MOST driver for Linux. Well, but of course, it works. At least it did in my environement (i386/single-CPU). You can find more information on the homepage ...

Interesting, because it was addressed to my gmx address in CC, Mutt automatically choosed my gmx address, and it seems that everybody can post to linux-kernel, even unsubscribed users.

Ok, that's perhaps the point for me to step in. I supervised the thesis of Bernhard within our Embedded Linux group at Siemens CT SE 2. Unfortunately, we currently don't plan doing further enhancements to this driver like porting it to other hardware. It was more or less an unplanned result of a thesis to show ways how to port drivers to a realtime extension - and as it was indeed a very good and usable result (thanks to Bernhard again!), we decided to open source it in the hope it might be useful. However, if a real user community forms around the project, we might rethink this decision. However I can't promise anything... > > It only supports synchronous data transfer.

You can make basic usage of the package without NetServices (we provide small examples which don't need NetServices), but for real-world product usage you might still need to buy a NetServices license from SMSC. -- Bye, Gernot Hillier Siemens AG CT SE 2 ^ permalink raw reply [flat|nested] 12+ messages in thread

It definitively works with 2.6.17. I just fixed it a few days ago to compile on 2.6.21 (ALSA was changed a bit ;)).

BTW: There _are_ patents on MOST, I think mostly NetServices, so it might be difficult. :( But IANAL.
