* add support for "physical devices" on skinny controllers.dlg2012-08-171-14/+183
| | | | | | | | | | | these controllers let you specify disks that should be accessed directly rather than be part of logical volumes. apparently you can plug in things like tape drives too. anyway, physical devices are exposed via a separate scsibus attached to mfi. ok mikeb@
* fix mfi_poll by having it do delays between loops, and breaking ondlg2012-08-161-35/+47
| | | | | | | timeouts. how embarrassment. implement mfi_exec for doing sync executions of commands in process contexts and cut mfi_mgmt over to it.
* rework mfi_poll so it will do all the completions on a ccb includingdlg2012-08-161-47/+45
| | | | | | | calling the done handler. this makes it consistently complete scsi io with all the proper error checking.
* stop passing mfi_softc around as a member of the ccb, consistently give itdlg2012-08-161-36/+30
| | | | as the first argument to functions. like mfii.
* scrub ccbs when we're about to use them, not when we put them backdlg2012-08-161-8/+16
| | | | | on the free list. ccbs can be reused, so we dont want old state screwing up new commands.
* move the dma syncs for the ccb data into ccb_done, so we can do it oncedlg2012-08-161-24/+10
| | | | rather than put the code everywhere.
* fix up the dma sync for the command frame in mfi_done.dlg2012-08-161-2/+3

* use scsi_get_link to find out the name of a child device for bioctl ratherdlg2012-08-141-12/+10
| | | | | | than snoop scsi commands and copy it in an io path. no functional change, but the code has one less XXX now.
* expose the max number of logical volumes the hardware supports as the widthdlg2012-08-141-12/+7
| | | | | | | | | | | | | | of its scsibus. only advertise 1 lun on logical volumes instead of letting the midlayer fix it up to 8. give every target on the bus max_cmds openings. iopools means they will properly share access to them. this in particular is useful on skinny controllers which only advertise 31 command slots. if you have 16 volumes, theyll only get 1 opening each with the old maths. this way round the ones that are busy will share the slots. tested on a perc5 with two volumes and hard workloads.
* print the boards name (eg, perc 5/i) according to the firmware like mfii.dlg2012-08-141-6/+6

* get rid of the last foo_lo and foo_hi bits i could find in the hardwaredlg2012-08-131-14/+6
| | | | | | | | | | structures and use htole64 instead of htole32(addr >> 32); htole32(addr); gets rid of "handy" stack variables to get the dva to 64bits. sprinkle some more byte swaps for things that should have it. tested on a perc5 (xscale)
* do appropriate bus_dmamapy_syncs around the pcq/completion ring.dlg2012-08-131-3/+14
| | | | tested on a perc5 (xscale)
* replace uint32_ts for hi and lo addresses in the mfi_init_ hardwaredlg2012-08-131-32/+16
| | | | | | | | | descriptors with single uint64_ts. theyre not some weird middle endian thing. this makes the code more readable. add some missing htole32s to the code while here. tested on a perc5 (xscale).
* the producer/consumer values are used by the device, which is littledlg2012-08-111-4/+4

* cut mfi over to using iopools.dlg2010-12-301-49/+42
| | | | | | | | | | | | this gets rid of NO_CCB, provides better scheduling of io between busy logical volumes on the same controller, and makes the ioctl and sensor paths more reliable. this is the least intrusive version of this change i could come up with. it only took 4 or 5 goes... ok marco@ deraadt@ says this is a good time for this change.

| | | | | | | | | | back from the chip on a command then the command completely failed. MFI_STAT_SCSI_DONE_WITH_ERROR really means the command completed fine, but there's some sense data too. this tweaks the handling to be more appropriate, as per the linux and solaris drivers. timed out waiting for beck@ putting this in cos its obviously more correct than the current code.

| | | | | | | | | | | | | void. Use XS_NO_CCB error in the scsi command (xs) to report the NO_CCB condition. Eliminates all SUCCESSFULLY_QUEUED and COMPLETE confusion and untangles the midlayer from the adapter a bit more. Eyes and some fixes by miod@ There may be some compile issues on little used (i.e. I don't have any) drivers but the change is mechanical and thus easy to remedy. ok dlg@

* scrub more fields in the ccb when returning them to the free list afterdlg2009-04-041-2/+6
| | | | | | | | | | theyve been used, in particular the mfi header flags which has a bit that specifies if a command should be completed via the interrupt path. if we use a ccb during boot we set that bit, but it isnt necessarily cleared by things that use it later on. this means a ccb we expected to complete via an interrupt never actually generates an interrupt or appears in the reply queue. this obviously stalls the io.

| | | | | | the sleep waiting for the completion. it is possible to get the interrupt completing the command just before the tsleep, which will never get a wakeup because the interrupt with the wakeup has already happened.
* Extend the scsi_adapter minphys() callback to take a struct scsi_link *miod2009-02-161-3/+3
