thorpej | Change the kqueue filterops::f_isfd field to filterops::f_flags, and
define a flag FILTEROP_ISFD that has the meaning of the prior f_isfd.
Field and flag name aligned with OpenBSD.
This does not constitute a functional or ABI change, as the field location
and size, and the value placed in that field, are the same as the previous
code, but we're bumping __NetBSD_Version__ so 3rd-party module source code
can adapt, as needed.

mlelstv | Make scsipi framework MPSAFE.
Data structures are now protected by a per-adapter mutex at IPL_BIO
that is created by the scsibus or atapibus instance when the adapter
is configured.
The enable reference counter and the channel freeze counter which are
currently used by HBA code before the adapter is configured, are made
atomic.
The target drivers are now all tagged as D_MPSAFE.
Almost all HBA drivers still require the kernel lock to present,
so all callbacks into HBA code are still protected by kernel lock
unless the driver is tagged as SCSIPI_ADAPT_MPSAFE.
TODO: refactor sd and cd to use dksubr.

- Some simplification in threading and sleepq subsystems.
- Eliminates pmap_collect() and, as a side note, allows pmap optimisations.
- Eliminates XS_CTL_DATA_ONSTACK in scsipi code.
- Avoids few scans on LWP list and thus potentially long holds of proc_lock.
- Cuts ~1.5k lines of code. Reduces amd64 kernel size by ~4k.
- Removes __SWAP_BROKEN cases.

bouyer | Make the xxstart() functions reentrant again, as some drivers HBA can call
scsipi_done() from their scsipi_request().
For this, add a struct scsipi_xfer * argument to scsipi_command().
If not NULL scsipi_command() will use this to enqueue this xfer, otherwise
it'll try to allocate a new one. This scsipi_xfer has to be allocated
and initialised by scsipi_make_xs() or equivalent.
In xxstart(), allocate a scsipi_xfer using scsipi_make_xs(), and if not NULL,
dequeue the buffer before calling scsipi_command(). This makes sure that
scsipi_command() will not fail, and also makes sure that xxstart() won't
be called again between the BUFQ_PEEK() and BUFQ_GET().
Fix "dequeued wrong buf" panics reported by Juergen Hannken-Illjes in
private mail and Andreas Wrede on current-users@.
Thanks to Jason Thorpe and Chuck Silver for review, and Andreas Wrede for

gehenna | Merge the gehenna-devsw branch into the trunk.
This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

bouyer | Pull up the thorpej_scsipi branch to main branch.
This is a completely rewritten scsipi_xfer execution engine, and the
associated changes to HBA drivers. Overview of changes & features:
- All xfers are queued in the mid-layer, rather than doing so in an
ad-hoc fashion in individual adapter drivers.
- Adapter/channel resource management in the mid-layer, avoids even trying
to start running an xfer if the adapter/channel doesn't have the resources.
- Better communication between the mid-layer and the adapters.
- Asynchronous event notification mechanism from adapter to mid-layer and
peripherals.
- Better peripheral queue management: freeze/thaw, sorted requeueing during
recovery, etc.
- Clean separation of peripherals, adapters, and adapter channels (no more
scsipi_link).
- Kernel thread for each scsipi_channel makes error recovery much easier
(no more dealing with interrupt context when recovering from an error).
- Mid-layer support for tagged queueing: commands can have the tag type
set explicitly, tag IDs are allocated in the mid-layer (thus eliminating
the need to use buggy tag ID allocation schemes in many adapter drivers).
- support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command
will be requeued, or a REQUEST SENSE will be sent as appropriate.

oops, bad patch
|
| 1.41 |
| 04-Jan-2000 |
mjacob | - If the user application issues an INITIALIZE ELEMENT STATUS which
succeeds, note that we now are valid.
- Don't attempt to try and run initialize element status from interrupt level-
we don't really support that yet. Also, key more correctly off of ASC/ASCQ
instead of just the sense key.
- Make the practice of doing an INITIALIZE ELEMENT STATUS automatically when
we get params (from chopen time even) a policy decision that is not the
default for now- this can be a dangerous practice as well as time consuming.
It's dangerous in that you can have a hung open when all you really want
to do is do a read of parameters- and parameters, including slot status,
are perfectly fine to read even before an INITIALIZE ELEMENT STATUS is
done- all the elements whos status your read are going to be marked with
an exception- so leave it up to the application to decide how important
this is.

thorpej | branches: 1.40.2;
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.

thorpej | Rework the changer driver a bit:
- Take note of magazine changes, and enqueue "Element Status Changed" events
that user processes can read or select on.
- Normalize some structure names.
- Report back more status about changer elements:
* Volume tags (e.g. barcode labels on the backs of your tapes)
* External device names (for drive units in a changer)
* Last element a unit of media was moved from
* Sense information for SCSI changer elements in EXCEPT condition
* Vendor-specific data if the user requests it.
- Add support for setting volume tags.

| 03-Jul-1998 |
mjacob | kern/5514: take the submitter's advice, at least partially. The time it
takes to do IELEM can be proportional to the number of elements, but is
also affected by wierd things like how readable the barcodes on the
media are. There are worst case scenarios I've seen where there are
white labels on the back of tapes with pencilled in labels which is
*just* close enough to being a bar code that an Exabyte 120 would
peer at them myopically and long enough for a *really* long time to
pass in inventorying the jukebox.
I've upped the limit to be proportional to 5 minutes per element. That
is long enough that someone I'm sure will complain about "you wait
to long and should time out" for broken h/w.
As is also noted in the PR, there are a lot of other issues here. It's
really also a question as to whether to update this driver or go
with CAM's driver. This one doesn't have switching between block
descriptors and not, doesn't support volume tag setting, and so on.
Time is limited. This PR should have been closed and fixed right away,
tho.

bouyer | Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
Main changes to the scsipi code itself:
- add a scsipi_channel->type to allow umass to attach to both atapibus and
scsibus. Will die when IDE is converted from ata_atapi_attach to
scsipi_channel/scsipi_adapter
- Add a chan_defquirks to scsipi_channel so that adapters can pass a default
set of quirks to be set for each device attached
- add adapt_getgeom and adapt_accesschk callbacks
|
| 1.40.2.1 |
| 19-Oct-1999 |
thorpej | Completely rewritten scsipi_xfer execution engine:
- All xfers are queued in the mid-layer, rather than doing so in an
ad-hoc fashion in individual adapter drivers.
- Adapter/channel resource management in the mid-layer, avoids even trying
to start running an xfer if the adapter/channel doesn't have the resources.
- Better communication between the mid-layer and the adapters.
- Asynchronous event notification mechanism from adapter to mid-layer and
peripherals.
- Better peripheral queue management: freeze/thaw, sorted requeueing during
recovery, etc.
- Clean separation of peripherals, adapters, and adapter channels (no more
scsipi_link).
- Kernel thread for each scsipi_channel makes error recovery much easier
(no more dealing with interrupt context when recovering from an error).
- Mid-layer support for tagged queueing: commands can have the tag type
set explicitly, tag IDs are allocated in the mid-layer (thus eliminating
the need to use buggy tag ID allocation schemes in many adapter drivers).
There is a lot more work to do, but this correctly functions for the most
part on several file servers I run.

fvdl | * add a VCLONED vnode flag that indicates a vnode representing a cloned
device.
* rename REVOKEALL to REVOKEALIAS, and add a REVOKECLONE flag, to pass
to VOP_REVOKE
* the revoke system call will revoke all aliases, as before, but not the
clones
* vdevgone is called when detaching a device, so make it use REVOKECLONE
to get rid of all clones as well
* clean up all uses of VOP_OPEN wrt. locking.
* add a few VOPS to spec_vnops that need to do something when it's a
clone vnode (access and getattr)
* add a copy of the vnode vattr structure of the original 'master' vnode
to the specinfo of a cloned vnode. could possibly redirect getattr to
the 'master' vnode, but this has issues with revoke
* add a vdev_reassignvp function that disassociates a vnode from its
original device, and reassociates it with the specified dev_t. to be
used by cloning devices only, in case a new minor is allocated.
* change all direct references in drivers to v_devcookie and v_rdev
to vdev_privdata(vp) and vdev_rdev(vp). for diagnostic purposes
when debugging race conditions that still exist wrt. locking and
revoking vnodes.
* make the locking state of a vnode consistent when passed to
d_open and d_close (unlocked). locked would be better, but has
some deadlock issues

thorpej | Commit my "devvp" changes to the thorpej-devvp branch. This
replaces the use of dev_t in most places with a struct vnode *.
This will form the basic infrastructure for real cloning device
support (besides being architecurally cleaner -- it'll be good
to get away from using numbers to represent objects).

darrenr | Apply the aborted ktrace-lwp changes to a specific branch. This is just for
others to review, I'm concerned that patch fuziness may have resulted in some
errant code being generated but I'll look at that later by comparing the diff
from the base to the branch with the file I attempt to apply to it. This will,
at the very least, put the changes in a better context for others to review
them and attempt to tinker with removing passing of 'struct lwp' through
the kernel.

he | Pull up revision 1.62 (via patch, requested by bouyer in ticket #837):
Improve handling of memory shortage, to fix problems like:
sd3(mpt0:0:1:0): unable to allocate scsipi_xfer
sd3: not queued, error 12
The theory is that other consumers of pool memory is causing
this memory shortage in certain somewhat hard to reproduce
situations.
This is done by giving scsipi_command an extra argument to
optionally pass a preallocated scsipi_xfer, and allocating a
scsipi_xfer before dequeueing a buffer in the various *start()
functions. If the allocation of a scsipi_xfer fails, schedule
a callout for delayed invocation of the start function. Also
reserve one page for scsipi_xfer structs, to ensure that we will
eventually have some available once pending commands complete.
Should fix PR#25670.
|
| 1.58.2.1 |

he | Pull up revision 1.60 (requested by seb in ticket #545):
Remove special handling of ASC/ASCQ 0x29/0x00 ("Power On,
Reset, or Bus Device Reset Occurred") when the device is
not opened. Let the default error handler deal with that
instead. This fixes the retreival of the sense page during
autoconfig.

mjf | - add "file-system DEVFS" and "pseudo-device devfsctl" to conf/std seeing
as these are always needed.
- convert many, many drivers over to the New Devfs World Order. For a
list of device drivers yet to be converted see,
http://www.netbsd.org/~mjf/devfs-todo.html.
- add a new device_unregister_all(device_t) function to remove all device
names associated with a device_t, which saves us having to construct
device names when the driver is detached.
- add a DEV_AUDIO type for devices.
