Hi all, there has been quite some activity regarding shared host-wide tag support for legacy HBAs, with several proposals floating around, but so far no consensus has been reached. Additionally some hardware (like megaraid or mpt3sas) have an internal queue split between 'normal' and 'high-priority' queues, which have no direct equivalent in blk-mq. I would like to discuss the best way forward for the shared tags implementation, and also if the 'blk_poll' interface to support io_uring can be mapped on the 'high-priority' queues existing in this hardware. Required participants: I would like to invite Ming Lei and John Garry, seeing that they contributed to this effort. Also hardware developers from Broadcom for the megaraid and mpt3sas drivers would be helpful as they could add some insights into the hardware.
