| | | | | | one bad case of use-after-free after a hell lot of heavy I/O creeping in again in this driver. This doesn't fix it but will hopefully help me diagnose once it occurs again.

* Change the scsi_cmd function member of scsi_adapter from int tokrw2010-03-231-10/+9
| | | | | | | | | | | | | 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@

* Make sure the scsi_xfer timeout is triggered while the command is still alive.miod2009-03-031-5/+11
| | | | | | | | | | With the current code, a fast command could complete between splx and the timeout being triggered, we'd then happily return COMPLETE, reuse the scsi_xfer, schedule the timeout again, causing a nice cycle in the timeout wheels. (I know, I know, I have to inspect all other scsi drivers now, but I'm really tired after spending three hours on this)
* Extend the scsi_adapter minphys() callback to take a struct scsi_link *miod2009-02-161-5/+3

* Better recovery when osiop goes nuts and spitsmiod2007-06-201-2/+9
| | | | | | | osiop0: osiop_select while connected? in loops. Before returning from the interrupt handler, whack the chip. Unfortunately, this causes the few i/o which were queued to time out, but this is better than spinning and eventually panicing.

* The first thing done when XXX_scsi_cmd() returns TRY_AGAIN_LATER iskrw2005-12-031-2/+1
| | | | | | | | to set xs->error to XS_BUSY. So it is pointless and misleading to set xs->error to XS_TIMEOUT, XS_DRIVER_STUFFUP or XS_BUSY just before returning TRY_AGAIN_LATER. No functional change.

| | | | | | | | | First, the only way to get there was if the timeout fired, in which case timeout_del() is a noop. Second, it will be called in osiop_scsidone() for every active command when osiop_reset() is called in osiop_timeout(). From mickey@

First cut at osiop driver (LSI Logic/Symbios/NCR 53C710). For hppa only at the moment. Functional for the most part, but there are known problems: 1) SCSI_CHECK/REQUEST_SENSE not handled at all - simply returns a zero'ed scsi_sense_data buffer. As a result all osiop sc_link's are created with the ADEV_NODOORLOCK quirk to suppress PREVENT_ALLOW commands from being issued (and failing) during probe. 2) Sync negotiation (wide is not supported on this chip) needs to be validated due to some ominous comments in the source about being valid only for the 33Mhz Zeus board. 3) Probe message needs fixing/completion to issue useful info. See 2). 4) Timeout/hangs occur under heavy load, e.g. make builds. From NetBSD. ok mickey@
