Re: Fwd: Compiling latest kernel (from kernel.org, linux-omap git version) in n800
Guillerm, thanks for your reply. So, about the use of --force-vermagic with busybox modprobe... What should I have to do to make busybox modprobe support --force-vermagic? get modprobe source code, and...? How about to use n770? The WLAN interface driver source code is available or it is like n800? Thank you, Leandro.

There is slightly quicker/easier but more hackish and definitely wrong way which may or may not work. You can set kernel version in main kernel Makefile to be what you want (i.e. the older one, see /proc/version on device) and then recompile kernel. Modules will load without changing insmod/modprobe but some may crash. Those that will crash need recompiling. The proprietary umac could works since in theory it should not use kernel API. The WLAN interface driver source code is available or it is like n800? Hopefully yes, in Maemo garage. So if this one will crash you could recompile it.

Sometimes silicon suppliers don't want to disclosure any source code cause major part of their offering is dependant on a software device driver. Shifting more low-level functionality to run as software device driver loads the CPU and memory heavily. Moreover, someone can wonder about the real value that is behind supplier's silicon solution.

False Nokia's tables exist today because people kept those GPL moral obligations. True but the opposite may be also true i.e. there would be no Nokia tablet if they could not use proprietary parts. Let's hope things will improve in future and we will have more completely open devices from other manufacturers. Or even from Nokia :-) Frantisek ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

Nokia's tables exist today because people kept those GPL moral obligations. Release functional source code of umac.ko please. Creating a device like Internet Tablet is not just writing software, it's a lot more. For example, one has to consider hardware design, costs, manufacturing, schedules and other issues. And when all these aspects are combined, the solution isn't always optimal. Just like the case is right now, as you have pointed out. I do understand the frustration of not having umac.ko sources available. I personally believe that having an open driver would improve the quality and make my job a lot easier. But that's just not possible currently and this is something we have to live with.
