It looks like `BASE` is a keyword in the .def file specification. https://github.com/bminor/binutils-gdb/blob/master/ld/deffilep.y#L241-L268 For several keywords, I could replicate the syntax error from ld.exe when the keyword was listed in EXPORTS in the .def file. As far as I can tell, the dllname-win.def file is a must in this case making sure none of the keywords get exported there. Also: https://access.redhat.com/document...

Hello everyone, This RFC implements packed ring support for virtio driver. The code was tested with DPDK vhost (testpmd/vhost-PMD) implemented by Jens at http://dpdk.org/ml/archives/dev/2018-January/089417.html Minor changes are needed for the vhost code, e.g. to kick the guest. TODO: - Refinements and bug fixes; - Split into small patches; - Test indirect descriptor support; - Test/fix event
