We've written a device driver in linux for a pcmcia card with usb and serial functionality. I need to test this driver on a dual core/SMP machine. We work on kernel 2.6.15.4. I have recompiled this kernel version on my dual core machine with the CONFIG_SMP flag set during menuconfig.
How do i ensure that my driver is making use of the SMP feature? Do build my driver code i have a makefile in which i use the EXTRA_CFLAGS= -D__SMP__ -DCONFIG_SMP -DLINUX. Am i using the right flags? Do these flags really have any significance in deciding whether the SMP capability will be exploited? Are there any other flags i need to use while building my driver code? What does the -jN flag mean? Should i be using it in my case.
Please guide me. I am a bit confused.
