This change arm, armeb, earm, earmeb, earmhf, earmhfeb so all builds that
share a MACHINE_ARCH for userland so that except for etc, will produce
identical sets.

usr/include/machine now points to usr/include/arm

Don't install fp.h anymore

branches: 1.24.2; 1.24.12;
On ARM-ish ports having PCI support, use new-style <sys/bus.h>. Do not
install <machine/bus.h>. Remove various <machine/bus.h> sources.

Retire varargs.h support. Move machine/stdarg.h logic into MI
sys/stdarg.h and expect compiler to provide proper builtins, defaulting
to the GCC interface. lint still has a special fallback.
Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.

Remove arm support for IPKDB.

It hasn't worked since arm was broken out from arm32 in Jan 2001, and
no-one has noticed or cared to fix it.

Remove KDIR=, since SYS_INCLUDE=symlinks and KDIR are not supported any more.

cats and netwinder can share a common footbridge_intr.h file, so install and
share a common file.

Add byte_swap.h for cats, this creates the /usr/include/machine/byte_swap.h

Implement pmc(9) -- An interface to hardware performance monitoring
counters. These counters do not exist on all CPUs, but where they
do exist, can be used for counting events such as dcache misses that
would otherwise be difficult or impossible to instrument by code
inspection or hardware simulation.

pmc(9) is meant to be a general interface. Initially, the Intel XScale
counters are the only ones supported.

branches: 1.12.8;
Delete <machine/psl.h> from the ARM ports. It's not a header that
we need to provide to MI code or to userland, and it's also not a
header that generic ARM code should be including directly.

Move disklabel_acorn.h to <sys/disklabel_acorn.h>, much like we did
with disklabel_mbr.h. More cleanup yet to come.

End the "new ARM includes strategy" experiment. The new strategy
broke too many assumptions makde by other parts of the source tree,

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.

Remove kerndebug.h from non-Shark code (it's a Shark-specific header
file, and probably should be done away with anyway).

Kill <machine/katelib.h>. Any place that still uses it should just
reference <arm/arm32/katelib.h> until such time as all use of this
file has been purged from the face of the earth.

branches: 1.7.6;
Add a merged <pcb.h> for arm26/arm32.

Use new shared arm/arm32/conf.c

Make <sysarch.h> valid for all arm platforms. Adjust/remove port-specific
includes as required.

branches: 1.4.2;
Add <arm/endian.h> and remove the cats, dnard and netwinder versions, since
they're all the same (a redirect to <sys/endian.h>).

Move <arm/arm32/bus.h> to <arm/bus.h>, since it looks like it's going to be
necessary on arm26 as well.

Per discussion at
<http://mail-index.netbsd.org/tech-kern/2010/04/02/msg007941.html>,
divide each machine's bus.h into bus_defs.h (constants & data types)
and bus_funcs.h (macro implementations of bus_space(9) routines and MD
prototypes).

Note that some bus_space(9) routines' implementation will move to .c
files from inline subroutines or macros in .h files.

I've only made the split for machine architectures where there is PCI.
All of the non-PCI-having architectures will require a similar split.

These #include files are not referenced by any (committed) Makefiles or
header files, yet. Changes to Makefiles, to <sys/bus.h>, and to some
more machine-dependent files will dribble in before I throw the switch.

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.

Make all ports use a common disklabel.h with MAXPARTITIONS set to 16.

Add getlabelusesmbr(), as proposed in
http://mail-index.netbsd.org/tech-userlevel/2011/08/25/msg005404.html
This is used by disk tools such as disklabel(8) to dynamically decide is
the undelyling platform uses a disklabel-in-mbr-partition or not
(instead of using a compile-time list of ports).
getlabelusesmbr() reads the sysctl kern.labelusesmbr, takes its value from the
machdep #define LABELUSESMBR.
For evbmips, make LABELUSESMBR 1 if the platform uses pmon
as bootloader, and 0 (the previous value) otherwise.

merge ktrace-lwp.

Make disklabel(8) and fdisk(8) into "host tools " last step: build
and install ${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-disklabel,
${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-fdisk by "reaching over" to
the sources in ${NETBSDSRCDIR}/sbin/{disklabel fdisk}/.

To avoid clashes with a build-host's header files, especially on
*BSD, the host-tools versions of fdisk and disklabel search for
#includes such as disklabel.h, disklabel_acorn.h, disklabel_gpt.h,
and bootinfo.h in a new #includes namespace, nbinclude/. That is,
they #include <nbinclude/sys/disklabel.h>, <nbinclude/machine/disklabel.h>,
<nbinclude/sparc64/disklabel.h>, instead of <sys/disklabel.h> and

cats and netwinder can share a common footbridge_intr.h file, so install and

Enable the use of a seperate statclock.

Currently statclock runs at 64hz, maybe it should be faster or slower, I did
try it being the same as hz, but that just made it look like we spent 10% of
time handling interrupts, rather than the 3% that this gives.

Also fix the IPL_LEVELS for netwinder.

netwinder and cats can share irqhandler.h, so move (and rename) into the
footbridge dir, and share it.

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.

Remove the needless inclusion of "opt_cputypes.h" in several places.
Convert remaining users to <arm/cpuconf.h>.

Remove a whole load of non-CATS stuff.

* Share a common vector page between arm26 and arm32.

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.

Finish up the changes to get LOOSE_PROTOTYPES working for cats.
Note that this leaves a few inconsistencies (no more than we already had though) eg initarm is now prototyped in arm32/machdep.h, however only cats currently makes use of that header.

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,
netbsd32 and rump.

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.

End the "new ARM includes strategy" experiment. The new strategy
broke too many assumptions makde by other parts of the source tree,
and the strategy and how it was supposed to work was never discussed
on tech-userlevel, nor was it applied consistently (to all ARM ports
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.

branches: 1.2.2; 1.2.8;
Eliminate all files that are just #include <arm.foo.h>. Update Makefile
to refer to cats, not netwinder.

Finish off the cats arch dir by creating an include dir and populating it from
arm32/include.
Make use of std.cats in the kernel config.

Fixup files.cats so it actually works.

- expose vmparams to userland on arm, like other archs do.
- remove unneeded includes

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.

branches: 1.28.2; 1.28.16;
expose more for kmemuser/fix include protection

Remove incomplete, never worked dynamic run-time memory registration
(uvm_page_physload(9)). This functionality will be re-added later.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

branches: 1.23.2;
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.

Back out last change, following jason's advice, it's lsof that's actually
broken not the headers.

Allow userland to see machine/vmparam.h. This allows ntop to compile, as it uses the struct uvm from uvm.h, which need the VM_NFREELIST definition.

Of course this does mean that ntop could potentially be platform specific, ie different versions for cats, acorn32 etc as struct uvm maybe a different size, but running on the same cpu architecture.

branches: 1.12.2;
cats has enough kvm space to use the default pager_map size.

* 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.

branches: 1.4.2;
Pull in common 32-bit ARM VM parameters.

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: 1.2.2;
Update vmparam.h to just have the cats value for KERNEL_VM_SIZE.

As noted by Robert Swindells.

Finish off the cats arch dir by creating an include dir and populating it from
arm32/include.
Make use of std.cats in the kernel config.

Fixup files.cats so it actually works.

merge ktrace-lwp.

branches: 1.1.2;
Factor out W{CHAR,INT}_{MAX,MIN} into their own header file.
