kernel source for 6000

As it was already mentioned on the other thread, Sharp has released it @ http://developer.ezaurus.com/sl_j/source/source_dl.htm

Interesting thing, unless I\'m completely blind, I can\'t find sources for either bluetooth module or wi-fi in 6000\'s kernel tree

Look for CONFIG_BLUEETOOTH_SL  in the patch. There\'s some bluetooth there. Dunno about wireless

WiFi driver is a prism2_usb binary in root_fs tarball. There is no bluetooth driver though...

That brings more questions than answers... So they have a binary compiled, but no source code? Did they compile it out of the kernel tree?

Since it resides on usb bus, there must be a usb hub inside sl-6000?

Well, true, they have a kernel configuration option for that. But I don\'t see any specific code in the kernel source they released yesterday.

drivers/char/serial_pxa200.c seems to contain the low level code.

I think the marketing materials said that the 6000 was capable of being usb host. As far as Wireless goes, the driver looks to be the wlan-ng usb prism driver. The source code for it does exist, but there is no telling whether or not sharp has modified it for their device. The easiest way to find out is  to compile a new copy and see if it works.

Ahh, my bad... obviously overlooked it, sorry.

Do we know which (if any) drivers are compiled into the kernel?

I don\'t think there is a bluetooth driver at all. The kernel config is not set to build bluetooth driver and I can\'t see a binary...

OK, I should probably remain silent and be thought a fool, but I\'ll open my mouth and remove all doubt:  Where did you find the configuration info that the kernel was built with?  I don\'t see a .config file in the source directory...

Only Kernel 2.6.x has the ability to reconstruct the .config out of a running system, but Anton probably refers to arch/arm/def-configs/tosa-j

Note that this not necessarily is the config the Sharp folks used to build the kernel.

Now that we have the source, are the deficiencies of the default kernel irrelevant?  What are the other hurdles to building custom kernels that address the issues of missing/incompatible drivers?

Yes, that\'s where I looked into
