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

Remove unused extended attributes kernel options

As Masao Uebayashi pointed to me, UFS_EXTATTR_AUTOSTART, LFS_EXTATTR_AUTOSTART
and UFS_EXTATTR_AUTOCREATE are not used anywhere in the code. Remove them
as they have been obsolete for a long time:
UFS_EXTATTR_AUTOSTART was replaced by mount -o extattr
LFS_EXTATTR_AUTOSTART was created to match obsolete UFS_EXTATTR_AUTOSTART
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)

Systematize (and in many cases, fix) the comments on options COMPAT_NN.

There are quite a few configs that are missing some COMPAT_NN options

Reorganize symbol table embedding. The existing option SYMTAB_SPACE is
replaced by the make option COPY_SYMTAB set to any value. The copy of
the symbol table is no longer put into a buffer in kern_ksyms.o, but a

the kernel is linked to compute the real dimension of the symbol table
buffer. After that, the helper object is rebuild and the kernel linked
again.

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

Checkin new interrupt handling code for the footbridge.
This is based upon Jason's work on xscale.

Most of the interrupt handling code is now written in C using an asm stub to
call into the C code.

spl* now only updates a software mask, and does not update the hardware,
this should be much faster.

The new code works well on cats, it's untested on netwinder, but should work.

The code implements generic soft interrupts.

More work is still required to bring the isa interrupt handling code upto
scratch currently all isa interrupts are handled at IPL_BIO on the footbridge.
This may cause isa interrupts to be handled later than they should be.
I plan to fix this in the near future.

called pckbc(4), and the new abstraction layer is "pckbport", so the
child devices have moved from sys/dev/pckbc to sys/dev/pckbport, which
also contains some code shared between all host controllers. To avoid
incompatibility, pckbdreg.h is still installed in
/usr/include/dev/pckbc.

In theory, this shouldn't cause any behavioural changes in the drivers
concerned. Thy just use rather more function pointers than before. Tested
on i386 and (with a new host driver) acorn32. Compiled on several other
affected architectures.

cleanup old lpt(4) attachment, and glue ppbus in so that they can coexist:
* lpt device is defined in MI place (dev/ppbus/files.ppbus), dev/ic/lpt.c
is included there too; dev/ic/lpt.c is not included if ppbus is
configured or if there is alternative platform lpt (like for pc532)
* g/c MD lpt definitions and custom puc/upc attachments,
glue moved to conf/files and dev/pci/files.pci respectively; remove
device lpt definition from dev/isa/files.isa
* add ppbus parport attribute, atppc device attachments, adjust plip and lpt
glue

Rename dsrtc to ds1687rtc to avoid conflicting with the MI i2c
ds1307 driver.

Hi Jason.

pciide_machdep.c depends on pciide_common, not pciide.
Pointed out and fix tested by Marc Recht.

branches: 1.28.6;
Checkin new interrupt handling code for the footbridge.
This is based upon Jason's work on xscale.

Most of the interrupt handling code is now written in C using an asm stub to
call into the C code.

spl* now only updates a software mask, and does not update the hardware,
this should be much faster.

The new code works well on cats, it's untested on netwinder, but should work.

The code implements generic soft interrupts.

More work is still required to bring the isa interrupt handling code upto
scratch currently all isa interrupts are handled at IPL_BIO on the footbridge.
This may cause isa interrupts to be handled later than they should be.
I plan to fix this in the near future.

now that mem_no is emitted by config(8), there is no reason to keep
copy of more or less identical iskmemdev() for every arch; move the function
to spec_vnop.c, and g/c machine-dependant copies

Merge isa_machdep.c from netwinder and cats into footbridge/isa (where it
joins other machdep files)
Saves maintaining multiple copies of the same thing, the only differences
were:
IRQ line used on the footbridge (made that a define in include/isa_machdep.h)
name of a dma_ranges variable contained arch name, so just made it generic.

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.

branches: 1.24.2;
* Move the mii_bitbang attribute into dev/mii/files.mii
* Pull in dev/mii/files.mii from conf/files, rather than playing
the magic "files include order" dance in N machine-dependent
configuration definitions.

Remove obsolete tests of "netwinder" and "footbridge".

Remove options NETWINDER and FOOTBRIDGE; nothing tests for them.

Update for death of arm32.

Reduce the massive code duplication regarding joy(4). Split it into
MI and MD parts, and make ISA/ISAPNP/PCI joy(4) attachments MI.

- convert usage of "defopt" to "defflag" where the relevant option does
not support a value (e.g., it's to be used as "options FOO" instead of
"options FOO=xxx"). options that take a value were converted to
defparam recently.
- minor whitespace & formatting cleanups

Move the interrupt-related file declarations into port-specific
config descriptions so that each port choose whether or not to
use it.

The ARM, Ltd. floating point emulator has moved to arch/arm.

cleanup:

Merge arm32/dev/bus_space_notimpl.S and hpcarm/hpcarm/bus_space_notimpl.S
into arm/arm/bus_space_notimpl.S. They were identical anyway.

This file has no excuse for being in assembler, but I'll leave that for another
day.

Move netwinder_machdep.c to files.netwinder. Eliminate opt_netwinder.h and
use #ifdef netwinder insead. XXX ebsa285_machdep.c should move to the cats
directory and files.cats

Move defopt FOOTBRIDGE to where it really should be in files.footbridge, which is where I should have left it.

Defopt FOOTBRIDGE.

Move towards common Makefile.arm
Add a netwinder/autoconf.c

Move blockio.S from sys/arch/arm32/arm32 to sys/arch/arm/arm, since I want to
start using it on arm26.

hpcarm gets to keep its own version, since it's not identical and I haven't
got an hpcarm box to test.

Add a files.footbridge for inclusion by cats and netwinder. This is to make moving of the footbridge dir easier (when it eventually moves from arm32)

Also remove EBSA285 defopt from the netwinder file as the netwinder isn't an eval board.

The arch/arm32/kshell code was removed three years ago. Kill references to it.

Move "defopt PMAP_DEBUG" into files.arm, since it's used by code in arch/arm.

Move cpufunc stuff from arm32/arm32 to arm/arm. The only change involved is
to add recognition of the SA-1100 and SA-1110 for compatibility with hpcarm
(which is now using this code as well).

branches: 1.2.2;

netwinder: kern.ldscript - preserve the .text section alignment

This change from evbarm was omitted in previous, but older binutils in
netbsd-10 seem to need it.

netwinder: fix base, minimize kern.ldscript diff with evbarm

New binutils align to 0x10000, not 0x8000 (which makes sense), so
adjust the base to be 0x10000 so that we are loaded at a page boundary
and (I guess) don't smash the firmware in the first page. While here,
sync with ldscript.evbarm.

Makes my netwinder boot again.

* Use a linker script to set the VMA/LMA appropriately for each section.
* Fix kernel page table allocation and mapping of kernel text/data/bss.

...and now that kernel images > 2MB work:
* Add SYMTAB_SPACE to the GENERIC kernel so that we have DDB symbols.
* Use dbsym to load the kernel's DDB symbol area.

netwinder: specify kernel make variables in the makefile

There's not much sense to specify makeoptions in std.netwinder for
config(1) to move them to the generated makefile, when there's already
Makefile.netwinder.inc where these variables can be specified directly.

Move ENTRYPOINT. Do NOT move LOADADDRESS - we don't want to use it as
it is kinda wrong and it will override the ld script. Instead
explicitly set LINKTEXT to be empty to avoid the common kernel
makefile to supply the unwanted -Ttext option.

Centralize ARM CPU configuration information by adding a new header
file, <arm/cpuconf.h>, which pulls in "opt_cputypes.h" and then defines
the following:
* CPU_NTYPES -- now many CPU types are configured into the kernel. What
you really want to know is "== 1" or "> 1".
* Defines ARM_ARCH_2, ARM_ARCH_3, ARM_ARCH_4, ARM_ARCH_5, depending
on which ARM architecture versions are configured (based on CPU_*
options). Also defines ARM_NARCH to determins how many architecture
versions are configured.
* Defines ARM_MMU_MEMC, ARM_MMU_GENERIC, ARM_MMU_XSCALE depending on
which classes of ARM MMUs are configured into the kernel, and ARM_NMMUS
to determine how many MMU classes are configured.

good.

* Removes the PMC code of ARM XSCALE.

* Removes all the pmc.h files. They were all empty, except for ARM XSCALE.

* Reorders the x86 PMC code not to rely on the legacy pmc.h file. The
definitions are put in sysarch.h.

* Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control
and sys_pmc_get_info syscalls. They are marked as OBSOL in kern,

Checkin new interrupt handling code for the footbridge.
This is based upon Jason's work on xscale.

Most of the interrupt handling code is now written in C using an asm stub to
call into the C code.

spl* now only updates a software mask, and does not update the hardware,
this should be much faster.

The new code works well on cats, it's untested on netwinder, but should work.

The code implements generic soft interrupts.

More work is still required to bring the isa interrupt handling code upto
scratch currently all isa interrupts are handled at IPL_BIO on the footbridge.
This may cause isa interrupts to be handled later than they should be.
I plan to fix this in the near future.

and to other ports which have common MACHINE_ARCH code, such as MIPS,
m68k, powerpc).

Verified to complete a full "make build" on cats, dnard, evbarm,
and netwinder.

Nuke include files which are just <arm/foo.h>. Adjust Makefile accordingly.

branches: 1.1.2;
Populate the netwinder include directory.

ISA exists on more that just shark. Fix a comment about this.

Use default PAGER_MAP_DEFAULT_SIZE for ARM and PowerPC, exception
acorn26. This bumps the KVA reservation from 4MB to 16MB and avoids
long hangs on my Cubietruck under IO. acorn26 is kept as it does have a
ridiculous low 32MB KVA limit.

Move KERNEL_VM_SIZE into the C files where its used.

Use virtual_avail and virtual_end to compute the size of the available
kernel VM space for VM_MAX_KERNEL_BUF, and move the definition into
generic ARM code.

Move KERNEL_VM_BASE inside where it is used (it won't be there for long).

Don't expose KERNEL_TEXT_BASE outside of board-specific code. This gives
individual board start-up code more flexibility about where the kernel
starts in the kernel address space.

Remove old pmap support for platforms which have fully switched over.

Don't define APTE_BASE if ARM32_PMAP_NEW is defined; the new pmap
doesn't use it.

Use PAGE_SIZE rather than NBPG.

Back out previous; it breaks binary compatibility between platforms
in the same MACHINE_ARCH.

Move some #defines out of _KERNEL.

* Change all uses of KERNEL_SPACE_START to KERNEL_BASE.
* Delete now unused KERNEL_SPACE_START.

Define KERNEL_TEXT_BASE, APTE_BASE, and KERNEL_VM_BASE in terms of
KERNEL_BASE.

* Rename PROCESS_PAGE_TBLS_BASE -> PTE_BASE
* Rename ALT_PAGE_TBLS_BASE -> APTE_BASE
* Garbage-collect PAGE_TABLE_SPACE_START

Implement pmap_growkernel for arm32 based ports.
Note that this has been compiled on some systems, cats, IQ80310, IPAQ, netwinder and shark (note that shark's build is currently broken due to other reasons), but only actually run on cats.
Shark doesn't make use of the functionality as I believe there has to be a correlation between OFW and the kernel tables so that calls into OFW work.

Move even more constants into the shared 32-bit vmparam.h header.
Cleanup elsewhere will have to be done before we can sanitize this
header any further.

- Move more contents of various <machine/vmparam.h> files into
<arm/arm32/vmparam.h> (mostly the stuff that's tied to the pmap
implementation).
- Since the MMU definitions in pte.h are specific to ARM processors
that support 32-bit mode, move pte.h to <arm/arm32/pte.h>.
- Make the Netwinder startup file build again (use PT_B|PT_C, rather
than PT_CACHEABLE, since the latter expands to a variable these days).

MAXSLP is defined to be a machine-independent scheduling parameter,
so move it into sys/param.h.

Checking a whole host of pmap changes:
Improved locking (not that we actually use it on a uniprocessor, but one day :)
Removed unneeded splvm's
tweaked pmap_clean_page code to only flush the cache if the page is mapped in the current pmap (based on diff from richard E)
Adopted pv entry allocation mechanism from i386.
Laid framework for returning ptp's when we've finished with them rather than holding onto them till the process exits.
ptp's are now allocated with a uvm object for the pmap, means that we can walk a list to free them off in pmap_release, until they get freed off by pmap_remove.

Also implemented a page zeroing function when the processor is idling. Note that hpcarm may wish to disable this.

I believe this code to be stable, if anyone has any problems please shout up.

branches: 1.3.2;
Per discussion w/ chuck and chuck, restructure the md page stuff
to use a structure called "vm_page_md", and use __HAVE_VM_PAGE_MD
and __HAVE_PMAP_PHYSSEG.

Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for
each vm_page structure. Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM. These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.

This deprecates struct pmap_physseg. As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.

Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now). Changes to other pmap
modules will follow.

Populate the netwinder include directory.

Factor out W{CHAR,INT}_{MAX,MIN} into their own header file.

Remove unnecessary <sys/malloc.h>.

split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.

branches: 1.11.2;
Do not call setroot() from MD code and from MI code, which has
unwanted sideeffects in the RB_ASKNAME case. This fixes PR/46732.

No longer wrap MD cpu_rootconf(), as hp300 port stores reboot information
as a side effect. Instead call MI rootconf() from MD code which makes
rootconf() now a wrapper to setroot().

Adjust several MD routines to set the global booted_device,booted_partition
variables instead of passing partial information to setroot().

Make cpu_rootconf(9) describe the calling order.

Interrupt handling changes, in discussion since February:

- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.

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.

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