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.

As Masao Uebayashi pointed to me, UFS_EXTATTR_AUTOSTART, LFS_EXTATTR_AUTOSTART

as they have been obsolete for a long time:
UFS_EXTATTR_AUTOSTART was replaced by mount -o extattr

UFS_EXTATTR_AUTOCREATE was replaced by sysctl vfs.ffs.extattr_autocreate

Support for UFS1 extended attributes in GENERIC and GENERIC-like kernels

This change just brings UFS1 extended attribute *support* in the kernel,
extended attributes are not enabled unless three conditions are met:
1) filesystem is UFS1 (newfs -O1)
2) .attribute/system and .attribute/user directories are created at fs root
3) filesystem is mounted with -o extattr

Some GENERIC kernels are obviously memory constrained, the extended
attributes options were not enabled for them, but just added commented out.
(kernel were considered memory constrained if QUOTA option was disabled)

Initial addition of tmpfs, an efficient memory file-system. This project
was developed as part of Google's Summer of Code 2005 program. This
change adds the kernel code, the mount_tmpfs utility, a regression test
suite and does all other related changes to integrate these.

The file-system is still *experimental*. Therefore, it is disabled by
default in all kernels. However, as typically done, a commented-out
entry is added in them to ease its setup.

Note that I haven't commited the required mountd(8) changes to be able
to export tmpfs file-systems because NFS support is still very unstable
and because, before enabling it, I'd like to do some other changes.

Comprehensive patches from Christian Limpach:
* Fix problems with the DMA and SCSI drivers.
* Make turbo machines sort of work.
Additional fixes from me:
* Determine if we're a turbo at boot time, by looking at the ROM machine type.
* Set the display size correctly (1120 pixels wide, but padded to 1152 only on
non-turbo machines).
Caveats:
* SCSI doesn't work on the turbo (or at least it blows chunks with no devices
attached).
* Media selection doesn't work on the turbo (the BMAP stuff doesn't exist on
turbo machines).
* The boot block is prone to timing out.

Change defaults for kernel compiles. Default all to USETOOLS?=no and have

simply adding USETOOLS=yes to the command line as usual.

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.

mark nsmb major obsolete

Systematize handling of removed drivers.

- Every driver that was removed and whose number hasn't already been
reused is now listed with a commented-out "obsolete" line.
- The format of these has been systematized. Future format changes can
probably be safely done with a script.
- This does not include a few cases of assignments that only lasted a
couple days, or stuff from before major reorgs. Some of these may
be included nonetheless, because there was a lot of ground to cover
and therefore not a lot of time to dig into history in detail.

Note that the obsolete listings do not mean the major numbers can
never be reused; that's up to portmasters and/or core. It does mean
that they won't be reused by accident, however, which in some cases
(depending on the driver, how widely used it was, its family of device
nodes, their default permissions, etc.) can be quite dangerous.

Note that some of the things now explicitly listed as obsolete are
really ancient history. My scan went back as far as when the majors
files were added. (But not before that.)

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.

resync bus_dma functions with current alpha versions.
added a field to a dma segment to return the actual length of that segment that

Change the pmap_extract() interface to:
boolean_t pmap_extract(pmap_t, vaddr_t, paddr_t *);
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: 1.7.4;
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.

next68k: Fix silent stall of next68k esp(4) SCSI.

next68k esp(4) driver requires nextdma(4) interrupts at ipl 6
during ncr53c9x_intr() for esp(4) at ipl 3. It worked on netbsd-5
and prior, but on netbsd-5 splbio() was changed from ipl 3 to 6
for SMP support and on netbsd-6 ncr53c9x driver was changed to
use mutex(9) instead of simple_lock(9), so nextdma interrupts
were no longer raised during ncr53c9x interrupt handler.

For now, just call mutex_exit(9) and mutex_enter(9) during
waiting nextdma(4) interrupts in MD esp_dma_intr() handler.
This could be wrong and the interrupt handler for nextdma should
be reorganized, but it just works.

Should be pulled up to netbsd-10 and netbsd-9.

Dynamically loadable bpf could probably be done fairly easily with
coordination from the stub driver and the real driver by registering
attachments in the stub before the real driver is loaded and doing
a handoff. ... and I'm not going to ponder the depths of unload
here.

DMA, not dma nor Dma.

bzero the part of the buffer used to pad the packet to
ETHER_MIN_LEN - ETHER_CRC_LEN.

Use CFATTACH_DECL().

more trailing \r cleanup; pointed out by wiz

Declare all cfattach structures const.

remove trailing \n in panic(). approved perry.

Comprehensive patches from Christian Limpach:
* Fix problems with the DMA and SCSI drivers.
* Make turbo machines sort of work.
Additional fixes from me:
* Determine if we're a turbo at boot time, by looking at the ROM machine type.
* Set the display size correctly (1120 pixels wide, but padded to 1152 only on
non-turbo machines).
Caveats:
* SCSI doesn't work on the turbo (or at least it blows chunks with no devices
attached).
* Media selection doesn't work on the turbo (the BMAP stuff doesn't exist on
turbo machines).
* The boot block is prone to timing out.

Apply patches from Christian Limpach:

- NeXT label reading support
- SCSI dma fixes
- media support for if_xe.c

Some of these need more cleanup, but at least make SCSI support usable on
the NeXT.

comment out device register structure definitions, used for reference only.
remove unnecessary BUS_SPACE_MAP_LINEAR when mapping ethernet dma registers.

branches: 1.4.4;
Make booted_device global (and booted_parition for consitency).
Eliminate it from header files and other extern definitions.

branches: 1.3.8; 1.3.16;
Continued work on esp scsi driver. Now can at least do enough i/o to create and mount
a filesystem, but is not stable enough yet for general use.
increased priority of ethernet interrupts, mostly useful to aid debugging
of scsi interrupts while using an nfs disk.
added additional debugging output in the next dma driver.
perform extranneous cache flushes/purges before dma reads/ after dma writes
to aid debugging of scsi dma.

Handle NeXT Turbo VRAM regions properly.

Info from Andreas Grabher on port-next68k@:
https://mail-index.netbsd.org/port-next68k/2023/02/06/msg000052.html

Also refactor bus_space_map(9) and fix (unused) bus_space_mmap(9).

Remove trailing spaces and TABs.

Misc KNF and cosmetics.

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
Sun OBP; any others?).

Declare all cfattach structures const.

Introduce a new routine, config_match(), which invokes the
cfattach->ca_match function in behalf of the caller. Use it
rather than invoking cfattach->ca_match directly.
