2008-06-25 13:30:29     driver as a module development taking more memory

Hi,

 

We created loadable module for WLAN. We observed that  when we do "INSMOD" WLAN it took around 8 MB of available memory where as when it is built in with the kernel it took around 2 MB.

 

Why module way of driver developing taking more memory?

 

Best Regards,Sreedhar.

how are you measuring memory usage ?  ELF sections will take up the same amount of space regardless (ignoring alignment/page padding).
