[dpdk-dev] [RFC][PATCH] bbdev: add raw operation support for additional offloads

[dpdk-dev] [RFC][PATCH] bbdev: add raw operation support for additional offloads

[Hemant Agrawal]

The exisiting bbdev APIs are limited for the lookaside FEC offload only.

The modem/FPGA can do much more than just the FEC offload. This patch
extend the operation to userdefined raw parameters, where they can
offload more than just the FEC offload processing. e.g. some of the
devices are capable of offloading large part of ORAN High-phy processing
as well.

Re: [dpdk-dev] [RFC][PATCH] bbdev: add raw operation support for additional offloads

[Chautru, Nicolas]

Initial question from a quick look, If you need a raw driver, cannot this be done by existing rawdev driver? Why should that fall under bbdev then?
