Rework how KERNOBJDIR functions; now it's always determined with
cd ${KERNSRCDIR}/${KERNARCHDIR}/compile && ${PRINTOBJDIR}
This is far simpler than the previous system, and more robust with
objdirs built via BSDOBJDIR.

The previous method of finding KERNOBJDIR when using BSDOBJDIR by
referencing _SRC_TOP_OBJ_ from another directory was extremely
fragile due to the depth first tree walk by <bsd.subdir.mk>, and
the caching of _SRC_TOP_OBJ_ (with MAKEOVERRIDES) which would be
empty on the *first* pass to create fresh objdirs.

This change requires adding sys/arch/*/compile/Makefile to create
the objdir in that directory, and descending into arch/*/compile
from arch/*/Makefile. Remove the now-unnecessary .keep_me files
whilst here.

Per lengthy discussion with Andrew Brown.

Reorganize installation if include files. Nuke some from atari/include as
they make no sense out of the kernel add some from atari/dev (ioctl's).

Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

Make these closer to working.

Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW

adaptions to config_search() change, and minor autoconf fixes, mostly from Havard Eidnes

Add use of __UNCONST() when passing a constant string to some of the
general autoconf functions which typically take a "void*". There may
be reason to revisit this later if the signature for the autoconf
functions can be adapted, but for now this gets the code building.

for drivers that support only one instance, use a global variable to ensure
that only one instance is configured rather than requiring that its
unit number be zero.

Remove what appears to be a spurious brace.

Extra bug fix on the config changes as implemented by Aymeric on the Amiga:
fake up a dv_cfdriver entry before calling config_search(). config_search()
does not do the lookup for us anymore.

Use aprint_normal() for cfprint routines.

Make things work with the new autoconf stuff:
- The pcibus is now called 'pcib' and the isabus 'isab'. Their attributes are
'pcibus' and 'isabus' respectively. This makes the underlying busses
attach again.
- Initialize the parent structure in the config_console() function.
Otherwise we end up without a console.

Overhaul the way cfattach structures are looked up. The cfdata entry
now carries the name of the attachment (e.g. "tlp_pci" or "audio"),
and cfattach structures are registered at boot time on a per-driver
basis. The cfdriver and cfattach pointers are cached in the device
structure when attached.

Use CFATTACH_DECL().

Add a config_init() function to initialize the config data structures.
Normally this is called by configure(), but some ports (amiga, atari,
x68k) need to do this early because of how they find the console.

Declare all cfattach structures const.

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to

- 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.

Move config_console() out of the grf-layer. This allows for more than just
grf-type consoles (wscons). Config_console() is now called from consinit(),
just after setting up the kernel msgbuf, so debugging is easy(er).
To further facilitate this move, the pcibus now allows for early-console
attaches by allocating static bus_space_tags (no mallocs possible at this
point).

printf -> kprintf, sprintf -> ksprintf

Second arg to print function is now 'const char *'

change cfprint_t type definition to take a const char *, rather than
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).

Yet more prototyping and -Wall fixes.

update for the fact that config_found() and config_rootfound() now
return pointers. (Check vs. NULL, rather than just boolean tests.)

Another bit of prototyping...

New device attachment scheme:

- split softc size and match/attach out from cfdriver into
a new struct cfattach.

- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.

Switch to the mi ramdisk driver.

First bunch of changes due to stricter prototype checking.

Add an nvram-driver. This driver makes it possible to read/write the
configuration info stored in the nvram on the mc146818.

Change the pmap_extract() interface to:

This makes it possible for the pmap to map physical address 0.

bus_dmamem_map() maps DMA safe memory, which is usually one or more
managed pages, into KVA space. Since the pages are managed, we should
use pmap_enter(), not pmap_kenter_pa().

Also, when entering the mappings, enter with an access_type of
VM_PROT_READ | VM_PROT_WRITE. We do this for a couple of reasons:

(1) On systems that have H/W mod/ref attributes, the hardware
may not be able to track mod/ref done by a bus master.

(2) On systems that have to do mod/ref emulation, this prevents
a mod/ref page fault from potentially happening while in an
interrupt context, which can be problematic.

This latter change is fairly important if we ever want to be able to
transfer DMA-safe memory pages to anonymous memory objects; we will need
to know that the pages are modified, or else data could be lost!

Note that while the pages are unowned (i.e. "just DMA-safe memory pages"),
they won't consume any swap resources, as the mappings are wired, and
the pages aren't on the active or inactive queues.

branches: 1.13.4;
Changes for modified pmap_enter() API:
* Map the message buffer with access_type = VM_PROT_READ|VM_PROT_WRITE `just

* Map the file system buffers with access_type = VM_PROT_READ|VM_PROT_WRITE to
avoid possible problems with pagemove().
* Do not use VM_PROT_EXEC with either of the above.
* Map pages for /dev/mem with access_type = prot. Also, DO NOT use
pmap_kenter() for this, as we DO NOT want to lose modification information.
* Map pages in dumpsys() with VM_PROT_READ.
* Map pages in m68k mappedcopyin()/mappedcopyout() and writeback() with
access_type = prot.
* For now, bus_dma*(), pmap_map(), vmapbuf(), and similar functions still use
access_type = 0. This should probably be revisited.

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.

- add dev_noimpl(xxx,yyy) macro to replace "(dev_type_xxx((*))) yyy",

- create more helper macros:
. cdev__xyz_init(c,n), such as cdev__ocri_init() for
/* open, close, read, ioctl */, etc.
. cdev__xRy_init(c,n), where nullop is used instead of enodev to dummy out
method `R' and the comments now read /* xxx (read) yyy */ instead
. cdev__xyz_t_init(c,n,t) - as per cdev__xyz_init, but sets d_type = t
as well

- use seltrue instead of dev_noimpl(poll,*), as (IIRC) cdevsw.d_poll should
always DTRT WRT returning a valid result. (a few devices previously
incorrectly returned ENODEV)

- use dev_noimpl(stop,enodev) instead of dev_noimpl(stop,nullop) if tty
== 0, because it doesn't matter if dev_type_stop isn't implemented in that
case, and it allows the use of the cdev__xyz_init macros. certain ports
(sparc,sparc64,x68k) used the nullop method for dev_type_stop in a few
drivers, whereas everything else uses enodev

Merge the ppcoea-renovation branch to HEAD.

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
every tree. Additionally there is a new PIC system that unifies the
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.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

pmppc was removed as an arch, and moved to a evbppc target.

Replace the myriad copies of bounds_check_with_label() with a single MI
version.

Add disk_blocksize(9) so that disk drivers can record the physical
block size of a disk if it is different to DEV_BSIZE. Right now this
simply initialises dk_blkshift and dk_byteshift according to the
supplied block size. This information is used in the MI version of
bounds_check_with_label().

rationalize the use of b_flags for geteblk() buffers.
rather than assigning to the whole field, set or clear individual flags,
which implies that the B_BUSY and B_INVAL flags will remain set.
this allows us to make the assertion in brelse() that B_BUSY is set,
which is the purpose of all this.

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.

TODO: revisit interaction between native compat and emul compat usage.

Don't clear the 'd_partitions' before starting to read the disklabel. Some
filesystems (iso9660) depend on the info they had already setup there.

Make this compile again.

Changes to bounds_check_with_label:
- Take care of the case where d_secsize < DEV_BSIZE (From Waldi Ravens)
- Don't check if an unsigned value <= 0. This was the cause of various
panics when savecore(1) was reading at bogus offsets because the crash
dump format was changed. Thanks to Jason for unintently revealing the
bug ;-)

Grok the broken ICD partition format. This should be part of the 1.2 patches.

Make dk_establish() a void function.

Corrections for removed <sys/cpu.h> and some more prototypes.

Correct #ifdef that survived the after-debug cleanup (Thanks Chris).

Another bit of prototyping...

First bunch of changes due to stricter prototype checking.

New disklabel handling code (Waldi Ravens).
These are the final (?) modifications to the layout of the NetBSD/Atari
bootblock. The bootblock handling can be made backwards compatible using
the right config options (COMPAT_11 + DISKLABEL_AHDI).

G/C the PTE/STE bits definitions from genassym.cf; they're not used by
assembly code, with the exception of PG_FRAME, which is not actually
used with PTEs but rather to truncate regular virtual addresses. As
such, provide an independent definition for it derived from PGOFSET,
decoupling it from PTE bits. XXX Should rename it to PGFRAME eventually.

Remove duplicated / slightly-tweaked loadustp() (load user segment table)
routines from all of the m68k ports using the shared pmap. Instead, in
pmap_init(), set up a function pointer to the appropriate mmu_load_urp*()
function in mmu_subr.s.

Re-factor the 680x0 Function Code definitions into their own
separate file (as was done on the sun2/sun3 ports ages ago)
and switch everyone to the common header.

Stop using magic numbers for the MMU root pointer attributes and the
Translation Control register, and also get rid of "#if PGSHIFT == ..."
where those magic numbers are used.

Instead, define new macros: MMU51_SRP_BITS, MMU51_CRP_BITS, MMU51_TCR_BITS,
and MMU40_TCR_BITS, in terms of the definitions in mmu_{40,51}.h. These
automagically adapt to 8K and 4K pages based on the machine-specific value
of PGSHIFT.
