quite possibly a silly question (which has never stopped me before),
but in perusing the PCIE code in the kernel source, i was looking for
sample code to demo in a classroom setting and picked on
drivers/net/wireless/iwlwifi/pcie, which i was *assuming* was
PCIE-dependent -- specifically, i was going to demo the Advanced-N
6235 PCIE wifi card on an intel galileo board.
but i thought it was a bit strange that the pcie/ subdirectory there
doesn't seem to depend on PCIEPORTBUS. as a test, i deselected
PCIEPORTBUS in a configuration and did a rebuild, and the source in
the pcie/ directory was recompiled.
am i misunderstanding the function of the kernel config variable
PCIEPORTBUS? i notice that .../iwlwifi/Makefile includes the line:
iwlwifi-objs += pcie/drv.o pcie/rx.o pcie/tx.o pcie/trans.o
which simply compiles those files with no regard to dependency. can
someone clarify this? thanks.
