in rev.1.30 (just before FreeBSD-1.1R) to almost match corresponding
breakage in FreeBSD-1.x's diskerr(). FreeBSD-2.x's diskerr() never
had the breakage.
in target mode, but we are not completing the command.
Use a template of allowed bus arbitration phases to selectively and
dynamically enable/disable initiator or target (re)selection.
Properly handle timeouts for target role transactions - just go to the
bus free state and report the error to the peripheral driver.
Checkpoint support for the XPT_ABORT_CCB function code. This currently
handles the accept tio and immediate notify ccb types, but does not
handle the continue target I/O or SCSI I/O ccb types. This is enough
to handle dynamic target enable/disable events.
Clean up the SCSI reset code so that we perform at most 1 SCSI bus
reset at initialization, the reset requested by the XPT layer.
level so they can be reclaimed before attempting to disable our lun.
Correctly free descriptors. Add periph locking and spl protection
around open and close.
pointed this out, but I've not seen a manifestation of this.
o Check against 0x00 as well as 0xff for geometry register, as some clone
cards don't return 0xff. Vadim Mikhailov pointed this out in PR
8743 for his Dell SCSI Array controller working in AHA-1540
emulation mode. Note that this test is likely to go away in the
future in favor of a better one Justin has recommended.
update their systems from prior versions of FreeBSD. It is only for
November 18, 1998 and newer systems. If you have an older system, you
are on your own.
I'll update this from time to time, and if it shows signs of bitrot
I'll kill it.
memory address space rather than IO space.. reflect this when looking for the
interface revision register.
If this is not true for them all then we probably need some smarter code.
to see if there's anything to do, schedule the next alarm
based on the next required timeout.
This decreases the load when there are lots of relatively
idle ppp processes.
While I'm in there, handle the possibility that a timeout
makes the timer element go out of scope by grabbing the
enext pointer before executing the timer function.
bug, but set it to 0 anyway to get rid of warning.
Get rid of uninitialized warning for local variable 'line' as well as
make a minor change to its scope. Again, no bug.
