Subject: [dpdk-dev] RTE_REGISTER_BUS does not work on Windows
Date: Thu, 23 Sep 2021 10:47:42 -0700 [thread overview]
Message-ID: <CALDO+SYy5Gsfz+8kKD80h5KXjwNJobTE4fL+5GPwbT3qOsAc6g@mail.gmail.com> (raw)
Hi,
I'm trying to run OVS-DPDK on Windows (building OVS binaries and
statically link DPDK windows library), and it doesn't work due to
rte_bus_scan() find no available devices. (However, when using
dpdk-testpmd.exe, it finds the device successfully)
I realized that the PCI bus driver calls RTE_REGISTER_BUS to
register itself, and it's a macro creating the businitfn_pci, and calls
rte_bus_register. But somehow on my system, it does not invoke
so actually the 'rte_bus_list' is empty. And I guess this is due to
"constructor" function not working correctly when I static link DPDK.
When linking DPDK using gcc, OVS passes the linker option '--whole-archive'.
https://github.com/openvswitch/ovs/blob/master/acinclude.m4#L509
I tried adding -Wl,-force_load, or -Wl,/WHOLEARCHIVE at libdpdk.pc.
So far I still couldn't get it to work. Any suggestions or comments are welcome!
Thank you
William
