I think there is no intention to make this run by application code, the functions need to be exported because driver and bus are different libraries. If above correct, there is no point of making the function experimental, can drop the __rte_experimental tag, and update .map file to not use EXPERIMENTAL. > +/** > * Register a ifpga afu device driver. > * > * @param driver > diff --git a/drivers/bus/ifpga/rte_bus_ifpga_version.map b/drivers/bus/ifpga/rte_bus_ifpga_version.map > index a027979..247ccfe 100644 > --- a/drivers/bus/ifpga/rte_bus_ifpga_version.map > +++ b/drivers/bus/ifpga/rte_bus_ifpga_version.map > @@ -8,3 +8,9 @@ DPDK_18.05 { > > local: *; > }; > + > +EXPERIMENTAL { > + global: > + > + rte_ifpga_find_afu_by_name; > +}; > \ No newline at end of file >
