* Prepare for future integration between CAM and newbus. xpt_bus_registerScott Long2007-06-171-1/+1
| | | | | | | | | | now takes a device_t to be the parent of the bus that is being created. Most SIMs have been updated with a reasonable argument, but a few exceptions just pass NULL for now. This argument isn't used yet and the newbus integration likely won't be ready until after 7.0-RELEASE. Notes: svn path=/head/; revision=170872
* Add in a couple of things:Doug Ambrisko2007-06-042-19/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - In the ioctl path let command get queued up and return when complete _without_ blocking the driving waiting for the response. This way the driver doesn't "lock up" for ~30s during a flash command. Submitted by scottl. - Add a guard so that if a DCMD of 0 is sent down the ioctl path don't send it to the controller. Return with a status of OK. This is a little strange since MegaCli doesn't seem to like something and will issue some DCMD of 0. This doesn't happen under Linux. So the emulation needs to be improved but I'm not sure what. Another strange thing is that when a DCMD of 0 gets issued under i386 the controller returns OK but in amd64 the context is messed up. - Add a guard so the context has to be with-in the legal limit so we get a reasonable error assertion versus random panic. It's going to be a challenge to figure out why MegaCli is not totally happy and then sends some bogus commands. This means that flashing firmware via the Linux tool won't work since it generates a DCMD of 0 when it should be opening the firmware for a flash update. Without this problem flashing works fine. This means there is no publicly available tool to upgrade the RAID firmware under FreeBSD right now. I plan to MFC all of the mfi changes to 6.X shortly. This might not include the SCSI pass-through changes. Submitted by: scottl Reviewed by: scottl MFC after: 3 days Notes: svn path=/head/; revision=170284

* Some relatively minor changes and bug fixes:Doug Ambrisko2006-12-143-65/+54
| | | | | | | | | | | | | | | | | | | | 1) s/mi/mfi/ in FreeBSD ioctl path 2) add in "\n" on various failure messages 3) cap the length of time to abort an AEN command 4) fix passing sense data back to user to make Dell's Linux firmware upgrade tool happy. 5) bump the MFI_POLL_TIMEOUT_SECS from 10s to 50s since the firmware flash command can take ~40s to return. This is some clean-up and enables RAID firmware to updated via Dell's tool. Note Dell's tool requires the updates to the Linux emulator that has been done in -current with TLS etc. I need to discuss with scottl how to better submit mfi commands to the firmware via the ioctl path so we don't do it in polled mode. Notes: svn path=/head/; revision=165225
* Change the internal API for polled commands. Calling mfi_polled_commandScott Long2006-11-181-83/+39
| | | | | | | | | | | | after calling mfi_mapcmd is no longer needed, so long as the MFI_CMD_POLLED flag is set. This change eliminates the possibility of a polled command getting posted twice to the driver. This is turn fixes panics on shutdown when INVARIANTS is set.

* Add in a bunch of things to the mfi driver:Doug Ambrisko2006-05-187-32/+1132
| | | | | | | | | | | | | | | | | | | | | | - Linux ioctl support, with the other Linux changes MegaCli will run if you mount linprocfs & linsysfs then set sysctl compat.linux.osrelease=2.6.12 or similar. This works on i386. It should work on amd64 but not well tested yet. StoreLib may or may not work. Remember to kldload mfi_linux. - Add in AEN (Async Event Notification) support so we can get messages from the firmware when something happens. Not all messages are in defined in event detail. Use event_log to try to figure out what happened. - Try to implement something like SIGIO for StoreLib. Since mrmonitor doesn't work right I can't fully test it. StoreLib works best with the rh9 base. In theory mrmonitor isn't needed due to native driver support of AEN :-) Now we can configure and monitor the RAID better. Submitted by: IronPort Systems.
