Fix to the messages output under CAM_DEBUG_CCB: the summary sense
information (error bits and sense key) is in the error field, not
in the result field, of struct ata_request. No other functional change.
This commit puts the relevant code snippets under #ifdef GONE_IN_5
(rather than #ifndef BURN_BRIDGES) thereby disabling the code now.
The code wil be entirely removed before 5.2 unless we find reasons
why this would be a bad idea.
Approach suggested by: imp
For the floppy driver, use fdcontrol to manipulate density selection.
For the CD drivers, the 'a' and 'c' suffix is without actual effect and
any applications insisting on it can be satisfied with a symlink:
ln -s /dev/cd0 /dev/cd0a
Ongoing discussion may result in these pieces of code being removed before
the 5-stable branch as opposed to after.
This will get rid of the warnings issued at shutdown (that seems to
worry alot of users), but will also no flush cache on lots of
devices that can, but doesn't set the right support bits...
Restructure the way ATA/ATAPI commands are processed, use a common
ata_request structure for both. This centralises the way requests
are handled so locking is much easier to handle.
The driver is now layered much more cleanly to seperate the lowlevel
HW access so it can be tailored to specific controllers without touching
the upper layers. This is needed to support some of the newer
semi-intelligent ATA controllers showing up.
The top level drivers (disk, ATAPI devices) are more or less still
the same with just corrections to use the new interface.
Pull ATA out from under Gaint now that locking can be done in a sane way.

receive 6 byte commands. Add a check for this flag to da(4) and cd(4) so
that they honor it. This is a quick workaround for many devices (especially
USB) that require da(4) quirks to operate. The more complete approach is
to finish the new transport code which will be aware of the SCSI version a
transport implements.

Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg.
Lockfunc allows a driver to provide a function for managing its locking
semantics while using busdma. At the moment, this is used for the
asynchronous busdma_swi and callback mechanism. Two lockfunc implementations
are provided: busdma_lock_mutex() performs standard mutex operations on the
mutex that is specified from lockfuncarg. dftl_lock() is a panic
implementation and is defaulted to when NULL, NULL are passed to
bus_dma_tag_create(). The only time that NULL, NULL should ever be used is
when the driver ensures that bus_dmamap_load() will not be deferred.
Drivers that do not provide their own locking can pass
busdma_lock_mutex,&Giant args in order to preserve the former behaviour.
sparc64 and powerpc do not provide real busdma_swi functions, so this is
largely a noop on those platforms. The busdma_swi on is64 is not properly
locked yet, so warnings will be emitted on this platform when busdma
callback deferrals happen.
If anyone gets panics or warnings from dflt_lock() being called, please
let me know right away.

succeeds. There is a difference between how OLDCARD and NEWCARD deal
with their resources, and this code exposes that difference. I'm not
sure which behavior is correct, and will need to look into that in
more detail. However, it appears that we go ahead and allocate the
right thing in both cases that I have access to (CF cards, CDROM, and
external ata enclosures), so go ahead and ignore the failure to get
the resource for the other rid. There's already another check to make
sure that the actual allocation works correctly, and that should be
sufficient to catch cases that don't work.

Retire the "d_dump_t" and use the "dumper_t" type instead.
Dumper_t takes a void * as first arg which is more general than the
dev_t taken by d_dump_t. (Remember: we could have net-dumpers if
somebody wrote us one!)
Define the convention for GEOM controlled disk devices to be that the
first argument to the dumper function is the struct disk pointer.
Change device drivers accordingly.
Change the argument to disk_destroy() to be the same struct disk * as
disk_create() takes.
This enables drivers to ignore the (now) bogus dev_t which disk_create()
returns.
a number of related problems along the way.
- Automatically detect CDROM drives that can't handle 6 byte mode
sense and mode select, and adjust our command size accordingly.
We have to handle this in the cd(4) driver (where the buffers are
allocated), since the parameter list length is different for the
6 and 10 byte mode sense commands.
- Remove MODE_SENSE and MODE_SELECT translation removed in ATAPICAM
and in the umass(4) driver, since there's no way for that to work
properly.
- Add a quirk entry for CDROM drives that just hang when they get a 6
byte mode sense or mode select. The reason for the quirk must be
documented in a PR, and all quirks must be approved by
ken@FreeBSD.org. This is to make sure that we fully understand why
each quirk is needed. Once the CAM_NEW_TRAN_CODE is finished, we
should be able to remove any such quirks, since we'll know what
protocol the drive speaks (SCSI, ATAPI, etc.) and therefore whether
we should use 6 or 10 byte mode sense/select commands.
- Change the way the da(4) handles the no_6_byte sysctl. There is
now a per-drive sysctl to set the minimum command size for that
particular disk. (Since you could have multiple disks with
multiple requirements in one system.)
- Loader tunable support for all the sysctls in the da(4) and cd(4)
drivers.
- Add a CDIOCCLOSE ioctl for cd(4) (bde pointed this out a long
time ago).
- Add a media validation routine (cdcheckmedia()) to the cd(4)
driver, to fix some problems bde pointed out a long time ago. We
now allow open() to succeed no matter what, but if we don't detect
valid media, the user can only issue CDIOCCLOSE or CDIOCEJECT
ioctls.
- The media validation routine also reads the table of contents off
the drive. We use the table of contents to implement the
CDIOCPLAYTRACKS ioctl using the PLAY AUDIO MSF command. The
PLAY AUDIO TRACK INDEX command that we previously used was
deprecated after SCSI-2. It works in every SCSI CDROM I've tried,
but doesn't seem to work on ATAPI CDROM drives. We still use the
play audio track index command if we don't have a valid TOC, but
I suppose it'll fail anyway in that case.
- Add _len() versions of scsi_mode_sense() and scsi_mode_select() so
that we can specify the minimum command length.
- Fix a couple of formatting problems in the sense printing code.
