Sync a list of HP-IB disk IDs with kernel's one.
Now bootloader can boot from 2202A, 7908A, 7911A, and 7941A.
Tested on 425t and HPDisk.

Make local variables static and read only ones const.

Use common macro for numbers of cylinders and blocks for HP-IB disks.
No binary changes.

Fix "rd(4) at punits not configured on HPDisk are misprobed" problem.
- check not only stat value returned by C_QSTAT command against
  each punit but also desc.d_name returned by C_DESC command
  because it looks HPDisk responds to commands against punits supported
  but not-configured punits at 1-3
- prepare rdreset_unit() function to manage reset punit ops during
  probe without valid softc

The stragety is taken from OpenBSD with several modification.
Tested on 425t with real 9122D and HPDisk emulating two 7937H drives.
Should be pulled up to netbsd-9.

Remove now unused buffer members from softc prepared only for rdreset().

Use proper integer types for HP-IB xfer parameters.
No visible regression on 425t and HPDisk.

Sync with rdreg.h integer type changes.

Remove unnecessary declarations.

Check bounds of RAW_PART by bounds_check_with_mediasize() as other drivers.
With this check, dd(1) without a count value against a raw partition
is terminated properly at the end of media.  Tested on 425t and HPDisk.
Should be pulled up to netbsd-9.

Check bounds of each partition by MI bounds_check_with_label(9).
The previous implementation was committed in rev 1.26 about 26 years ago
and it looks there is no quirk to use the old MD one.

Pass a correct dev_t arg to disk_ioctl().
Probably harmless.

Remove a duplicated static function declaration.

Set disk_geom parameters required by DIOCGPARTINFO in disk_ioctl().
With this change raid(4) no longer complains before mountroot:
RAIDframe: can't get disk size for dev rd0 (22)
Should be pulled up to netbsd-9.

Use proper RAW_PART macro rather than a magic number.

Remove more duplicated static function declarations.

Misc KNF and cosmetics.

Add empty DIOCCACHESYNC ioctl(2) for rd(4).
Without this raid(4) always complains on various raidctl(8) ops:
raid0: cache flush[0] to component 0 failed (22)
RAID1 configured by raid(4) just works HP-IB disks on hp300.

Explicitly include <sys/kernel.h> for hz(9) as man pages says.

Pull HP-IB probe fixes from OpenBSD/hp300.
https://marc.info/?l=openbsd-cvs&m=113217630426615&w=2

Overhaul the way HP-IB devices are probed. We will now do an exhaustive
probe of the (slave, punit) tuple space, since this is the only way we
can get a dual disk or dual tape enclosure to attach two devices of the
same kind.

This allows using multiple rd(4) disk images on the same slave emulated
by HPDisk (and probably the real 9122D with dual floppy disk drives).

Thanks to Miod Vallat for suggesting this fix.

Move attach messages from common rdident() to explicit rdattach().

https://marc.info/?l=openbsd-cvs&m=113227249626888&w=2

Define the CS/80 identify structure only once and correctly, instead of
duplicating it in every CS/80 driver and using an hardcoded number for
its size.
No functional change.

We have three sets of DTYPE_ constants in the kernel:
	altq		Drop 		Type
	disklabel	Disk 		Type
	file		Descriptor	Type
(not to mention constants that contain the string DTYPE).
Let's make them two, by changing the disklabel one to be DisK TYPE since the
other disklabel constants seem to do that. Not many userland programs use
these constants (and the ones that they do are mostly in ifdefs). They will
be fixed shortly.

make more drivers use disk_ioctl, and add a dev parameter to it so that
we can merge the "easy" disklabel ioctls to it. Ultimately all this will
go do dk_ioctl once all the drivers have been converted.

Be a little more clear and consistent about harvesting entropy from devices:

1) deprecate RND_FLAG_NO_ESTIMATE

2) define RND_FLAG_COLLECT_TIME, RND_FLAG_COLLECT_VALUE

3) define RND_FLAG_ESTIMATE_TIME, RND_FLAG_ESTIMATE_VALUE

4) define RND_FLAG_DEFAULT: RND_FLAG_COLLECT_TIME|
   RND_FLAG_COLLECT_VALUE|RND_FLAG_ESTIMATE_TIME

5) Make entropy harvesting from environmental sensors a little more generic
   and remove it from individual sensor drivers.

6) Remove individual open-coded delta-estimators for values from a few
   places in the tree (uvm, environmental drivers).

7) 0 -> RND_FLAG_DEFAULT, actually gather entropy from various drivers
   that had stubbed out code, other minor cleanups.

- remove unused
- use cpu_{g,s}etmodel

Change (mostly mechanically) every cdevsw/bdevsw I can find to use
designated initializers.

I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.

Don't pass NULL struct dkdriver to disk_init.  That's seriously bogus.

Entropy-pool implementation move and cleanup.

1) Move core entropy-pool code and source/sink/sample management code
   to sys/kern from sys/dev.

2) Remove use of NRND as test for presence of entropy-pool code throughout
   source tree.

3) Remove use of RND_ENABLED in device drivers as microoptimization to
   avoid expensive operations on disabled entropy sources; make the
   rnd_add calls do this directly so all callers benefit.

4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might
   have lead to slight entropy overestimation for some sources.

5) Add new source types for environmental sensors, power sensors, VM
   system events, and skew between clocks, with a sample implementation
   for each.

pullup (widespread #ifdef removal and moved files).  Tested with release

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in

interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

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.

sleep() -> tsleep()

A foolish consistency; most parts of the kernel use bp->b_data, so
change these from bp->b_un.b_addr to bp->b_data, as well.  This also
allows us more flexibility to experiment with other data buffer types
hung off of struct buf.

New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

Runs on i386, needs work on other arch's. Main kernel routines should be
fine, but a number of the stand programs need help.

cd, fd, ccd, wd, and sd have been updated. sd has been tested with non-512
byte block devices. vnd, raidframe, and lfs need work.

Non 2**n block support is automatic for LKM's and conditional for kernels
on "options NON_PO2_BLOCKS".

Update for changes to config.

Update marc-pcmcia branch from trunk.

Copyright assigned to The NetBSD Foundation.

Remove old *_UNK style default defines, use standard names from locators.h.
Missed in "locators.h" cleanup; reported by Thorsten Frueauf in PR 3906.

Remove misplaced/unnecessary VM #include cruft; from Thorsten Frueauf
<frueauf@ira.uka.de> in PR port-hp300/3851.

foosize()'s return value is in DEV_BSIZE units; adjust the size obtained
from the disklabel accordingly.

Update for USELEDS changes.

Use the %x printf format where appropriate

Fix printf() and other warnings when compiled with DEBUG defined.

Add prototypes, and make this compile with -Wall.  Remove register
modifier from all declarations.

Convert to new-style autoconfiguration; old-style config is no longer
supported.

Bring some sanity into my frazzled existence:
- Always ensure that RAW_PART ("c") can be opened.
- Disallow unused or non-existent partitions from being opened.
- Don't do bounds checking or partition translation on RAW_PART.
This is consistent with other disk drivers in the NetBSD source tree,
and fixes a condition where the user could not fix a corrupted disklabel
due to a bogus offset for partition "c".

Set the device class on non-dull devices.  This is a transitional thing.

backout previous kprintf changes

printf -> kprintf, sprintf -> ksprintf

Fix kernel crash dumps.  Still uses the old format for now.

Update from trunk:

Remove old-style disk instrumentation support.  Nothing uses it
anymore.

Remove the old-style disk instrumentation support.  Nothing uses it
anymore.

All interrupt routines (except the HIL; don't ask) now take a pointer
to a softc, rather than a unit number.  Add a "dq_softc" member
to struct devqueue; this is a temporary measure until the
dma/controller/device callback spaghetti is untangled.

YAY!  No more need for dcafastservice!

HIL: squish instances of "(void) splhil()" and "(void) spl0();".

Remove bogus "return (0);" in rdmatch() that wiggled its way in uninvited.

Kludge around a case where a flaky HP-IB disk might be slow to respond
to the identification request in rdmatch().  Similar in spirit to a
patch from Jason Downs (written eons ago), but limited to the broken
device we're trying to reach.  My patch tested (and fixed :-) by
Herb Peyerl.

New generic disk framework.  Highlights:

	- New metrics handling.  Metrics are now kept in the new
	  `struct disk'.  Busy time is now stored as a timeval, and
	  transfer count in bytes.

	- Storage for disklabels is now dynamically allocated, so that
	  the size of the disk structure is not machine-dependent.

	- Several new functions for attaching and detaching disks, and
	  handling metrics calculation.

Old-style instrumentation is still supported in drivers that did it before.
However, old-style instrumentation is being deprecated, and will go away
once the userland utilities are updated for the new framework.

For usage and architectural details, see the forthcoming disk(9) manual
page.

Pass the correct number of arguments to readdisklabel().

Use a "match/attach" rather than "init" scheme for probing devices.
This is a step towards getting the drivers ready for new config.

Re-arrange things such that we can print out disk geometry regardless of
COMPAT_NOLABEL.

XXX One day when the world doesn't assume DEV_BSIZE bytes/sector, we'll be
able to actually use the stuff sensed from the drive, rather than a table.

Pass correct number of arguments to hpibgo().

Update for conf.h changes.

kernel_pmap --> pmap_kernel()

new RCS ID format.

Bug fixes from Mike Hibler.

Merge with 4.4-Lite.

Get rid of private *read() and *write() functions.

Most of the changes needed to make this continue to run.

Add arg to ioctl functions.  Clean up #includes.

*strategy functions return void.

Add RCS identifiers (this time on the correct side of the branch), and
incorporate recent changes in netbsd-0-9 branch.

add rcsids to everything and clean up headers

add hp300 kernel files.  generic kernel files might need some help...
