- scsi prototypes.
- Add SCSI scanner support by Kenneth Stailey and Joachim Koenig-Baltes,
hacked a but. Needs more work.
ss.c:
- Truncate to the window size in ssminphys(), not ssread().
- Missed some prototyping foo.
- Minor tweak; make sure window size is 0 on close.
- Change variable name to avoid GCC warning.
- Handle EOF a little differently.
|
|
- Implement DIOCLOCK and DIOCEJECT. DIOCEJECT is limited to removable
media. Fixes PR #1975.
- scsi prototypes
|
|
|
|
|
|
|
|
- Accept DIOCEJECT as a synonym for CDIOCEJECT. Implement DIOCLOCK
separately from CDIOCALLOW and CDIOCPREVENT, even though they perform
basically the same function (with a different interface XXX).
- scsi prototypes

- scsi prototypes
- remove #ifdef notdef made unnecessary by previous changes (PR#1597)
put in missing "if (error)" that caused tape IO to always fail.
(closes PR#2086)
- Minor change.

Honor cache request and add the SCSI tape device configuration page.
Fixes PRs 807, 1201, and 1705. From John Kohl <jtk@kolvir.blrc.ma.us>.

"command aborted" status)
Handle cases like the following:
- controller calls scsi_done() with error XS_TIMEOUT
- scsi_done() calls sddone()
- sddone() calls disk_unbusy()
- scsi_done() calls controller to retry command (missing the
call to disk_busy())
- controller calls scsi_done()
- scsi_done() calls sddone()
- sddone() calls disk_busy(), which panics because of the imbalance.
Bug noticed by Leo Weppleman, who also suggested this fix; pass an additional
boolean argument ("complete") to the device's "done" routine, with a
value of `0' passed from the previous call to "done", and add an additional
call to "done" when the xfer resources are freed.

This might be a transient error. Do complain about it, though.

New generic disk framework. Highlights:
New metrics handling. Metrics are now kept in the new `struct disk'.
Busy time is now stored as a timeval, and transfer count in bytes.
Storage for disklabels is now dynamically allocated, so that the size
of the disk structure is not machine-dependent.
Several new functions for attaching and detaching disks, and handling
metrics calculation.
Old-style instrumentation is still supported in drivers that did it
before. However, old-style instrumentation is being deprecated, and
will go away once the userland utilities are updated for the new
framework.
For usage and architectural details, see the forthcoming disk(9)
manual page.

If the read or write request can fit into a 6-byte cdb, then
use a 6-byte cdb, otherwise use the 10-byte as before.
In sdattach(), make a note if the device is "ancient" (i.e.
inqbuf.version & SID_ANSII == 0).
Implement sdminphys(): if the device is "ancient", shorten the
transfer so it will fit into a 6-byte cdb.
In sdminphys(), add a comment about the semantics of the "length" field
in a 6-byte read/write cdb (namely, length == 0 really means 256), and
that we handle this conservatively by limiting the transfer to 255 blocks.
*sigh* One just never knows how a pre-scsi-1 device is going to behave.
Remove a couple of now unneeded assignments.

add a bunch of rogues
Trim NULs, in addition to spaces, in scsi_strvis().
