bouyer 6dd47fe65f Abort transfer if b_blkno is negative. Closes PR kern/5553 by Johan Danielsson. 1999-02-10 12:29:50 +00:00
bouyer f6f9f8a965 Change DIOCEJECT to do what's needed to eject a device before the eject
command (unlock for sd and cd) if no other partitions are open, return
EBUSY otherwise. DIOCEJECT will have the old semantic if its argument is not
0. The old ioctl has been renamed to ODIOCEJECT for binary compatibility.

bouyer 12868a7d80 Return ENODEV instead of EIO when we are trying to open a device without media
in the drive. restrict "opening of empty drive" to character devices only
(reading a block device returns a short read instead of ENODEV, which can lead
to confusion).
1999-01-29 11:17:58 +00:00
bouyer f52c71b0e8 Allows the raw partition to be open()'ed, even when scsipi_start() fails
(no media or other ...) so that we can always send ioctl's to the device.

thorpej b3b533c44d Keep track if the disk has had done i/o, making it dirty. On last close,
or at shutdown, flush the cache if the disk is still dirty and it support
cache flushing.  Fixes PRs #5588 (Jim Bernard) and #5589 (Justin Gibbs).

drochner 32fce55082 Improve generation of default disklabels:
-store printable product ID in cd's and sd's softc, use it as "typename"
-for this, add a "destination buffer length" argument to scsipi_strvis()
-return ATAPI device type for ATAPI devices

SCSIVERBOSE and the new ST_ENABLE_EARLYWARN.

mjacob 66ea6cc018 Fix for kern/3835: add an sd sense handler. If we get a check condition/sense
data ASC/ASCQ of 0x04/0x01 (logical unit not ready, initialization in progress),
hang out for 5 seconds and return a RETRY THE OPERATION command. If we
get a check condition/sense data ASC/ASCQ of 0x04/0x02 (logical unit not
ready, initialization command required), send a polled/nosleep START UNIT
command and return a RETRY THE OPERATION command if that succeeds.

Don't send a START UNIT to a disk quirked as SDEV_NO_START. Don't send
a START UNIT to removable media. The reason for the latter is to not
just blindly spin up new (maybe changed) media.

I should note that I've successfully made this work with the ISP host
adapter so far. Other host adapters will need some work to be able
to manage or reasonably fail NOSLEEP/POLL commands while in this
state. Alternatively, the internal SCSI midlayer structure has got
to allow for more controlled error recovery (e.g., restart queues
controlled by the target driver).

cgd 3b207eaf83 add support for an ATAPI attachment for 'sd'.
fix 'cd' driver's NCD_SCSI bogosity (was using testing wrong macro!)
clean up in various ways:
* make common atapi_mode_{sense,select}() functions.
* put ATAPI data structures in more sensible headers, split up by
  device type.
* include headers a bit more carefully.
* pass flags to attachment-specific cd functions, and use them.
* get rid of SCSI bits in scsipi_base.h's scsipi_make_xs(), move
  them into the correct place in scsi_base.c.
* fix minor typo in struct name in scsipiconf.h (which was apparently
  never used except in a #define later in the same file).
* use __attribute__ to force 4-byte alignment for xs command store,
  so that architectures trying to bus_space_write_multi_N() (where
  N > 1) that data to a controller won't lose.
* clean up a few comments in typos, and make a few #defines easier to
  understand/maintain.
* rename cd_link.h to cdvar.h (via repository copy).  This is exactly
  what a 'var' file is supposed to be.

enami d7d845c3d2 Cosmetic changes to keep coding style consistency in this directory;
- Indent with tab of width 8.
- Use four column to indent continuation line.
- Fold long line if possible.
- Use return (xx) instead of return xx.
- Compare pointer against NULL instead of testing like boolean.
- Delete whitespace at the end of line.
- Delete whitespace in front of function call operator.
- Delete whitespace after cast.
- Dereference a pointer to function explicitly.
- Add an empty line after local variable declaration.
- Use NULL instead of (char *)0.
- Dont use block for single statement.

bouyer 6f3bab1f59 Merge scsipi branch in the mainline. This add support for ATAPI devices
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.

mycroft aca1dae3c4 Push the buffer cleanup code into scsi_done(), and split it so that biodone()
is called *after* the driver `done' routine.  This fixes disk I/O statistics
on SCSI devices.

Also, calling the `done' routine with a `complete' argument of 0 and actually
having it do anything meaningful loses in at least 3 ways, so just nuke the
argument altogether and don't call it this way.  If the driver needs to do
some error handling, that's what `err_handler' is for.

matthias c53ad1988a * At least the Teac FC-1 Shugart-SCSI bridgeboard does motor on/off
management by itself. But when it gets a start unit request, it keeps
the floppy motor running all the time. This adds code for dealing with
yet another quirk (SDEV_NOSTARTUNIT) that prevents sd.c from sending
start unit requests. A entry for the Teac FC-1 is added to the quirk
table.
