So I recompiled driver in this SMP system with CFLAG including "__SMP__".
The driver cannot be comiled due to following errors:
gcc -c -g -O -D__SMP__ -D__KERNEL__ -DMODULE -DFCLayer_TachyonTL -I../h
-I../common/h -I/usr/src/linux/include hpfc.c

make: *** [hpfc.o] Error 1
Could anyone help me on this issue please!
1, To compile a driver with SMP enabled, what flag should be defined?
2. What else do I need to make driver compiled for SMP?
Many thanks!
