Re: [microblaze-uclinux] loadable module support in petalinux kernel2.6



The below was in reference to kernel loadable modules (.ko).  I don't know if .so is supported.

Hi,
does loadable module support also mean that user applications can dynamically link against .so files?
Cheers, F@lk

Can you post the full patch with the header file changes described 
below, or is it online?

Thanks for your help!

That was quick, indeed. I have just tried to compile the SMC91C111
driver as a module and was able to load the required modules, to
configure the network and to connect to the outside world.
As soon as I have more time for this I will continue testing.
        
Sounds good.

      
 * microblaze_modules.patch - the core loadable module support

 * platform_module_fixup.patch - a fixup to the handling of the 
platform_device initialisers, so that they work correctly 
          
when the 
    
associated device drivers are built as modules.  See the 
          
comment at 
    
the top of microblaze?platform/common/Makefile for details.
          
I have applied both patches to a clean petalinux-v0.20-rc3 
        
directory.
    
Your patches did not include the changes I made to 
include/asm-microblaze/elf.h and include/asm-microblaze/module.h.
Is there any special reason for this? I was not able to compile the
kernel with module support without patching those two files.
        
Ah - an omission on my part.  Will report the patches shortly, with 
your header file changes.
