Hi, I'd like to participate in LSF/MM and would like to present/discuss ideas for introducing I/O scheduling support to blk-mq. Motiviation for this is to be able use scsi-mq even on systems that have slow (spinning) devices attached to the SCSI stack. I think the presentation/discussion should consist of the following (1) short overview how blk-mq currently performs with spinning devices (in comparison to CFQ) (2) information about my attempt to introduce per sw queue time-slice to blk-mq to mitigate the performance degradation with spinning devices (in comparison to CFQ) (3) hopefully I can share information about working code for another approach to introduce I/O scheduling for blk-mq (which I am currently looking into) (4) other ideas (e.g. toggle blk-mq per host and/or why we won't look into it) Thanks, Andreas -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
