> This series adds new devcmd2 support. The first two patches are code > refactoring. > > devcmd is an interface for driver to communicate with fw/adaptor. It > involves writing data to hardware registers and waiting for the result. > This mechanism does not scale well. The queuing of "no wait" devcmds is > done in firmware memory rather than on the host. Firmware memory is a > rather more scarce and valuable resource than host memory. A devcmd storm > from one vf can disrupt the service on other pf/vf. The lack of flow > control allows for possible denial of server from one VM to another. > Devcmd2 uses work queue to post the devcmds, just like tx work queue. This > allows better flow control.
