enami 5a4b9fcbbf Prevent a process being swapped out during I/O if the data buffer is
allocated on stack.  This potential problem is noticed by Noriyuki Soda
and the idea and sample code to fix is given by Jason R. Thorpe.

augustss 997c3c5b8a Add a quirk, SDEV_ONLYBIG, which implies that the device cannot handle
the 6 byte versions of READ, WRITE, and MODE_SENSE.
This greatly simplifies the UFI (USB Floppy) handling.

thorpej 463931b3ba Nuke dk_establish() from orbit except from those ports which still use
it to determine the boot device: mvme68k, pc532, macppc, ofppc.  Those
platforms should be changed to use device_register().  In the mean time,
those ports defined __BROKEN_DK_ESTABLISH.

thorpej fe551f0e64 Fix a bug in disksort_*() which caused non-optimal ordering when multiple
active partitions were on a single spindle.  Add a b_rawblkno member to
struct buf which contains the non-partition-relative block number to sort
by.

mycroft 8efdaab402 Fix the size of start_sector, end_sector and end_sector_l0. (I'm just going to
assume the Linux people will also fix this, since I reported it to them.)

mycroft e45ef6abcd Emulate the Linux DVD_* ioctls(2). This gets us 90% of the way to running the
LiViD DVD player.  (See forthcoming mail to current-users.)
XXX NOTE: We should do something to probe capabilities, rather than allowing
these ioctls on any device.

ragge 2674b15280 Don't call dk_establish() on vax either. 1999-10-17 09:44:48 +00:00
thorpej 16a9d90e17 Cleanup the scsipi_xfer flags:
- `flags' is now gone, replaced with `xs_control' and `xs_status'.
- Massive cleanup of the control flags.  Now we explicitly say that
  a job is to complete asynchronously, rather than relying on side-effects,
  and use a new flag to now that device discovery is being performed.
- Do SCSI device discovery interrupt-driven.

bouyer b87dbb8918 in cdclose(), ignore "media change" when calling scsipi_prevent(), after
a 'eject -l' some ATAPI drives report this instead of illegal request.
1999-05-27 11:19:04 +00:00
bouyer e91bdf1c67 Add SCSI_IGNORE_NOT_READY to the flags for CDIOCCLOSE: some devices will
attempt to spin up, and report an error if there's no CD. Fixes port-i386/7345.

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.

-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

cgd 10f936ff29 move the 'cd_cd' declaration back up to where it was before
the config changes were made.  Though the nature of the declaration
had to change, there wasn't a reason to change its location.

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 8178ae5997 Uses PLAY_MSF instead of PLAY for the CDIOCPLAYTRACKS ioctl. This avoid a int16
overflow in the PLAY cbd when the resquested track(s) are more than 65535
blocks long. Submitted by t-nkyma@tcp-ip.or.jp in PR kern/4092.

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.
