0b7ed341e1 Change the disk(9) API in order to make device removal more robust.
Previously the "struct disk" were owned by the device driver and this
gave us problems when the device disappared and the users of that device
were not immediately disappearing.

Now the struct disk is allocate with a new call, disk_alloc() and owned
by geom_disk and just abandonned by the device driver when disk_create()
is called.

Unfortunately, this results in a ton of "s/\./->/" changes to device
drivers.

Since I'm doing the sweep anyway, a couple of other API improvements
have been carried out at the same time:

The Giant awareness flag has been flipped from DISKFLAG_NOGIANT to
DISKFLAG_NEEDSGIANT

A version number have been added to disk_create() so that we can detect,
report and ignore binary drivers with old ABI in the future.

Manual page update to follow shortly.

6e9e1e9753 Dont re-arm the timeout twice on a timeout error.
The problem with the first timeout still exsists though, but not
it doesn't enter a groundbound spin loop :)

aad970f1fe Use __FBSDID().
Also some minor style cleanups.

38d8c9940b Prefer new location of pci include files (which have only been in the
tree for two or more years now), except in a few places where there's
code to be compatible with older versions of FreeBSD.

b539f9d523 Instead of not grapping a request binfinish(ENOMEM) it if malloc fails. 2003-04-02 11:36:43 +00:00

891619a66d Use bioq_flush() to drain a bio queue with a specific error code.
Retain the mistake of not updating the devstat API for now.

Spell bioq_disksort() consistently with the remaining bioq_*().

#include <geom/geom_disk.h> where this is more appropriate.

60794e0478 Centralize the devstat handling for all GEOM disk device drivers
in geom_disk.c.

As a side effect this makes a lot of #include <sys/devicestat.h>
lines not needed and some biofinish() calls can be reduced to
biodone() again.

5cd0cc885f NO_GEOM cleanup:
Move to "struct disk *" centric API.
Add NULL check to a malloc(9) return value.

595ecc67ab Fix so it compiles with the new disklabel stuff. 2002-09-27 21:56:35 +00:00

7812d86f03 (This commit touches about 15 disk device drivers in a very consistent
and predictable way, and I apologize if I have gotten it wrong anywhere,
getting prior review on a patch like this is not feasible, considering
the number of people involved and hardware availability etc.)

If struct disklabel is the messenger: kill the messenger.

Inside struct disk we had a struct disklabel which disk drivers used to
communicate certain metrics to the disklayer above (GEOM or the disk
mini-layer).  This commit changes this communication to use four
explicit fields instead.

Amongst the benefits is that the fields do not get overwritten by
wrong or bogus on-disk disklabels.

Once that is clear, <sys/disk.h> which is included in the drivers
no longer need to pull <sys/disklabel.h> and <sys/diskslice.h> in,
the few places that needs them, have gotten explicit #includes for
them.

The disklabel inside struct disk is now only for internal use in
the disk mini-layer, so instead of embedding it, we malloc it as
we need it.

This concludes (modulus any mistakes) the series of disklabel related
commits.

I belive it all amounts to a NOP for all the rest of you :-)

27da7e6f24 Finally first shot at a driver for the Promise SuperTrak SX6000 ATA RAID
controller. Some testing has already been done, but its still greenish.
RAID's has to be setup via the BIOS on the SuperTrak, but all RAID
types are supported by the driver. The SuperTrak rebuilds failed arrays
on the fly and supports spare disks etc etc...

Add "device	pst" to your config file to use.

As usual bugsreports, suggestions etc are welcome...
