https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=235181 --- Comment #7 from Michael Osipov <michaelo@FreeBSD.org> --- I did some code digging: mrsas_cam.c sets by default "ccb->cpi.base_transfer_speed = 150000", in my case camcontrol.c says that the transport is SPI (parallel SCSI) (Why not SAS?) In XPI mode the transfer speed is calculated with a sync rate and bus width. Both are never set. So I guess the lowest possible value is assumed. mfiutil/mrsasutil does not display the value at all. I bet that Broadcom's closed source util can display this piece of information. I searched drivers for those bitrate fields, most don't set it. I assume that this displayed value is totally useless at least for mrsas(4) and deceiving. I'd be happy if someone could prove or revoke my analysis. -- You are receiving this mail because: You are the assignee for the bug.home | help
