* Replace a plethora of historical protection options with justderaadt2014-11-161-4/+4
| | | | | | | PROT_NONE, PROT_READ, PROT_WRITE, and PROT_EXEC from mman.h. PROT_MASK is introduced as the one true way of extracting those bits. Remove UVM_ADV_* wrapper, using the standard names. ok doug guenther kettenis

| | | | | | | Bogus chunks pointed out by matthew@ and miod@. No cookies for marco@ and jasper@. ok deraadt@ miod@ matthew@ jasper@ macro@

* Remove all adapter-specific 'struct scsi_device's. They are never used. Firstkrw2010-06-281-10/+1
| | | | | | | | step in elminating 'struct scsi_device' entirely. Spotted and initial diff from matthew@. ok matthew@ dlg@ deraadt@ marco@ miod@
* Don't #include <sys/user.h> into files that don't need the stuffguenther2010-06-261-2/+1
| | | | | | | | it defines. In some cases, this means pulling in uvm.h or pcb.h instead, but most of the inclusions were just noise. Tested on alpha, amd64, armish, hppa, i386, macpcc, sgi, sparc64, and vax, mostly by krw and naddy. ok krw@
* New scsi code seems to be stable. Pluck previously identifiedkrw2010-05-201-5/+1
| | | | | | | low-hanging splbio/splx pairs that are no longer needed and see if this reveals any hidden scsi flaws. ok dlg@
* s/i386/__i386__/, no binary change.kettenis2010-04-281-2/+2

* Change the scsi_cmd function member of scsi_adapter from int tokrw2010-03-231-8/+15
| | | | | | | | | | | | | 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@
* A couple of missed ITSDONE setting before scsi_done().krw2010-01-101-2/+1
| | | | | | | seagate/trm/aha1742 were the only drivers paranoid enough to check ITSDONE on getting the xs to execute. And optimistic enough to think simply restting the flag would be a good thing. Have them chill out like everyone else, reducing ITSDONE noise some more.
* Bring last drivers fully into the NO_CCB world by replacingkrw2009-11-221-3/+2
| | | | | | | | | | | TRY_AGAIN_LATER uses with equivalent NO_CCB. Eliminates confusion between the two as was always intended. buf I/O's that can't be started get pushed back onto the front of the queue and retried. Others get sent back to originator as failures. No more epi-cycle looping inside the SCSI midlayer hoping the problem goes away. Various testers, no objection from miod@ as vs(4) was tested by nick@.
* directly calling Debugger() is bad. turn these printf();Debugger(); seriesjasper2009-08-261-21/+8
| | | | | | into panic()'s. ok deraadt@ jsing@
* Convert the waitok field of uvm_pglistalloc to "flags", more will be added soon.oga2009-04-141-5/+5
| | | | | | | | | For the possibility of sleeping, the first two flags are UVM_PLA_WAITOK and UVM_PLA_NOWAIT. It is an error not to show intention, so assert that one of the two is provided. Switch over every caller in the tree to using the appropriate flag. ok art@, ariane@
* Extend the scsi_adapter minphys() callback to take a struct scsi_link *miod2009-02-161-5/+3
| | | | | | as additional argument. This will allow intermediate layers between scsi devices such as sd and scsi host adapters to take appropriate action if necessary.
* Replace timeout_add(msecs * hz / 1000) with timeout_add_msec(msecs).grange2009-01-211-2/+2
| | | | | | No functional changes. ok krw@ miod@

* give scsi controllers a real attach args to fill in when attaching scsibus.dlg2006-11-281-2/+6
| | | | ok miod@ marco@ deraadt@
* 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.
