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

inspection or hardware simulation.

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

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

Move disklabel_acorn.h to <sys/disklabel_acorn.h>, much like we did

No need for <machine/rtc.h> here.

Remove __BUS_SPACE_HAS_STREAM_METHODS

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.

Clean up evbarm interrupt support a little:
* Define an ARM_INTR_IMPL option, which specifies a header file
describing the interrupt implementation for the platform. Use
this instead of the list of EVBARM_BOARDTYPE checks.
* Make the s3c2xx0 interrupt dispatch code a bit more generic, and move
it to a generic location so that other platforms can use it.

This eliminates all uses of the EVBARM_BOARDTYPE stuff, so delete it.

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.

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,

they #include <nbinclude/sys/disklabel.h>, <nbinclude/machine/disklabel.h>,

Some interrupt controllers can select polarity of interrupt signals.
add IST_LEVEL_{LOW,HIGH} and IST_EDGE_{FALLING,RISING,BOTH} for them.

Clean up evbarm interrupt support a little:
* Define an ARM_INTR_IMPL option, which specifies a header file
describing the interrupt implementation for the platform. Use
this instead of the list of EVBARM_BOARDTYPE checks.
* Make the s3c2xx0 interrupt dispatch code a bit more generic, and move
it to a generic location so that other platforms can use it.

This eliminates all uses of the EVBARM_BOARDTYPE stuff, so delete it.

fix root detection on evbarm when raid is involved

there are several problems solved in this change:
- lots of work was re-done when we already have determined the
device booted from, so several new early returns introduced
if booted_device has been set
- due to the lack of cpu_bootconf(), raidframe softroot would
override "root=xxx" on the boot command line (note that
platforms that use eg, device_register() to detect the boot
device are not affected by this issue as they find the
boot device much earlier.)
- in the new cpu_bootconf(), switch the order of the platform
boot-config with the set_root_device() call. this avoids a
problem where "root=xxx" is checked after automated methods,
and is thus ignored.
- in fdt_detect_root_device(), remove the code to add "root=xxx""
string to the boot_args[] that would be later parsed by the
set_root_device() call, and simply set booted_device and, for
mbr installs, booted_partition directly. also, for any
successful call, perform an early return.
- define __HAVE_CPU_BOOTCONF so early boot calls cpu_bootconf().


tested on:
- rockpro64 booting from emmc, sata (big, and little endian)
- rockpro64 loading kernel from msdos partition
- rockpro64 booting from network (fails to auto-detect, with or
without this change)
- quartz64 booting from nvme
- lx2k booting from nvme

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.

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.

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

Add initial support for ARMv8 (AARCH64) (by nisimura@ and ryo@)

- sys/arch/evbarm64 is gone and integrated into sys/arch/evbarm. (by skrll@)
- add support fdt. evbarm/conf/GENERIC64 fdt (bcm2837,sunxi,tegra) based generic 64bit kernel config. (by skrll@, jmcneill@)

FDTise RapberryPI support. Thanks for jmcneill for a lot of help with this.

The kernel image that the RPI firmware boots is now netbsd.img in the
kernel build directory.

XXX fdtbus_get_reg needs reworking

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

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

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 KERNEL_TEXT_BASE, et al, if ARM32_NEW_VM_LAYOUT is defined.

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.

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

* Add support for running the IQ80310 kernel where KERNEL_BASE !=
physical memory start. Garbage-collect some cruft while here.
* Move the kernel up to 0xc0000000, giving a 1G/3G kernel/user split.
* Adjust the Integrator startup code accordingly.

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.

branches: 1.7.2;
Correct KERNEL_TEXT_BASE.

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: 1.3.2;
Pull in common 32-bit ARM VM parameters.

Fix a comment. EV boards don't always use a Footbridge.
