Hi Mike,
I don' think EXPORT_SYMS works right.
EXPORT_SYMS= fw_asybusy \
fw_asyreq \
fw_bindadd \
getcsrdata \
fw_xfer_alloc \
fw_xfer_free \
By this configuration, /sys/conf/kmod.mk generates space separated
list to export_syms like this:
fw_asybusy fw_asyreq fw_bindadd getcsrdata fw_xfer_alloc fw_xfer_free
But /sys/conf/kmod_syms.awk expects 'line break' separated list.
And we cannot export any symbols.
For example,
Remove ppbus/plip/lpt/ppi/ppc from you kernel config.
Can you load ppbus and it's childen by kldload?
Even if this problem is fixed, I suppose another problem there.
Even if I set EXPORT_SYMS=YES, I cannot resolv module symbols.
e.g.
kldload module1
kldload module2
module2 cannnot resolv symbols in module1.
-stable doesn't have this problem.
