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.

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.

Initial commit of the splitting off of arch/acorn32 from arch/arm32.

The IOMD/VIDC combination is now moved to arch/arm/iomd together. These
files still need a lot of cleaning up :( .... esp. the RC7500 support that
is still dormant in it; this needs either to be removed or split out for
RC7500's ``VIDC'' video/audio variant.

Apart from the RC7500 support wich is still in arch/arm32 the
iomd,vidc,riscpc and podulebus subdirectories of arch/arm32 can be removed.

This split still uses some small parts of arch/arm32 .... those are the MI

up any fallout before 5.0.

Remove LKMs and switch to the module framework, pass 1.

Proposed on tech-kern@.

It is not appropriate to call pmf_system_shutdown(9) from
doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9)
expect to be called with interrupts disabled, but shutdown hooks
registered with pmf_device_register1(9) expect to be called with
interrupts enabled. So I have made two changes:

1 Do not call pmf_system_shutdown() from doshutdownhooks(). Instead,
change every call to doshutdownhooks() to a call to doshutdownhooks()
followed by a call to pmf_system_shutdown(). No functional change
is intended by this change.

2 Make i386 re-enable interrupts briefly while it calls
pmf_system_shutdown(). I leave it to others either to fix the
other ports, or to factor out some MI shutdown code, as joerg@
suggests, and fix that. Note that a functional change *is* intended
by this change.

I hope that this patch will stop us from flip-flopping between
calling doshutdownhooks() and pmf_system_shutdown() sometimes with
and sometimes without interrupts enabled.

Further tweaks to Kinetic support. All memory in ths sytem is now used.
Non-Kinetic memory is placed into a seperate freelist so preference is
given to the kinetic memory.

Add support to support code for Kinetic card. The kernel is loaded into
the Processor local memory, so that should provide a speed up.

Currently DMA won't work, as we only tell the kernel about the kinetic
memory, and exclude the motherboard memory. I'll look at fixing this over
the weekend.

Add support for kernels > 4MiB. The -current INSTALL kernel has now hit
25KiB over 4MiB and we were only adding L1 mappings for 4MiB.

Also added lots of tracing which I used to work out what boot32 was doing,
and so what the kernel was meant to be doing. This is disabled by default.

Out of paranoia also become a client of all domains before setting the ttb,
just in case RISC-OS ever decides to use domains.

All of this has been tested on my Kinetic Risc-PC. I've carried out a full
install onto it, and hope to use it for testing out the interrupt work I've
been doing.

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

Fully switch acorn32 to the new pmap; it has been confirmed to work.

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.

Reduce differences between ARM32_NEW_VM_LAYOUT and not; always pass
the start and end of the kernel managed virtual address space to
pmap_bootstrap() in the new pmap.

Eliminate PTE_BASE and the PT-PT completely in the ARM32_PMAP_NEW case.
Also in the ARM32_PMAP_NEW case, reclaim the USPACE-bytes of wasted space
at the top of the user address that hasn't been needed for a very very
long time.

Add support for ARM32_PMAP_NEW. Note that due to changes to how the l1
table is handled the podulebus mappings are now done at initarm, rather
than in the podulebus code. While I'm not happy with this it does work,
perhaps there's a better way to do it?

Not enableing by default I've not got enough cards to check the podulebus
change hasn't broken something (works with my rapide and with my network
podule)

Typo and comments

Update the NetBSD part for the bootloader change. Mostly the changes in
bootconfig.h needs reflection

ANSIfy. Un-__P().

KNF -- this file was making my eyes hurt.

No functional change.

Found the issue with the kinetic bootloader.

Seems that we assume that the dram blocks are sorted, and that the first/lowest address is also where the kernel is.

If the above is not true, then we're on a kinetic (probably should make a better way to indicate this) So search for all dram blocks < with starting addr lower than the first block and remove them.

Currently there's minimal performance gain (which is odd as the SDRAM is meant to be faster, I'm wondering if we need to prod some hidden registers to set timing information.

Note that I still get 16MB/s compared with 7MB/s on RiscStation and 93MB/s on my cats. I'm thinking that something else is seriously nasty on acorn32.

Enable caching on kernel and user page tables. This saves having
to do uncached memory access during VM operations (which can be
quite expensive on some CPUs).

We currently write-back PTEs as soon as they're modified; there is
some room for optimization (to write them back in larger chunks).
For PTEs in the APTE space (i.e. PTEs for pmaps that describe another
process's address space), PTEs must also be evicted from the cache
complete (PTEs in PTE space will be evicted durint a context switch).

* Add PTE_SYNC() and PTE_SYNC_RANGE() macros. These don't actually do
anything yet.
* Use PTE_SYNC() and PTE_SYNC_RANGE() in some obvious places, i.e.
where vtopte() is used.

Do cached memory access to L1 tables, making sure to write-back the
cache after any L1 table modifications.

Move the calls to uvm_page_physload() out of pmap_bootstrap() and
into platform-specific initialization code, giving platform-specific
code control over which free list a given chunk of memory gets put
onto.

Changes are essentially mechanical. Test compiled for all ARM
platforms, test booted on Intel IQ80321 and Shark.

Discussed some time ago on port-arm.

Move the uvm_setpagesize() call to platform-dependent code in preparation
for other changes to pmap_bootstrap().

Reviewed by Jason Thorpe.

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>.

vm_offset_t -> vaddr_t,paddr_t

* Split pte_cache_mode into pte_l1_s_cache_mode, pte_l2_l_cache_mode,
and pte_l2_s_cache_mode. The cache-meaningful bits are different
for these descriptor types on some processor models.
* Add pte_*_cache_mask, corresponding to each above, which has a mask
of the cache-meangful bits, and define those for generic and XScale
MMU classes. Note, the L2_S_CACHE_MASK_xscale definition requires
use of the Extended Small Page L2 descriptor (the "X" bit overlaps
with AP bits otherwise).

Use abstract names for the protection and PTE type bits in
L1 and L2 descriptors. This will allow us to support different
PTE layouts that enable the use of extensions on different
processor models.

* Rewrite the 32-bit ARM pte.h based on the ARM architecture manual.
Significant cleanup, here, including better PTE bit names.
* Add XScale PTE extensions (ECC enable, write-allocate cache mode).
* Mechanical changes everywhere else to update for new pte.h. While
doing this, two bugs (as a result of typos) were fixed in

arm/arm32/bus_dma.c
evbarm/integrator/int_bus_dma.c

Clean up handling of the vector page on 32-bit ARM systems:
* Don't refer to VA 0, instead refer to a new variable: vector_page
* Delete the old zero_page_*() functions, replacing them with a new
one: vector_page_setprot().
* When manipulating vector page mappings in user pmaps, only do so if
the vector page is below KERNEL_BASE (if it's above KERNEL_BASE, the
vector page is mapped by the kernel pmap).
* Add a new function, arm32_vector_init(), which takes the virtual
address of the vector page (which MUST be valid when the function
is called) and a bitmask of vectors the kernel is going to take
over, and performs all vector page initialization, including setting
the V bit in the CPU Control register ("relocate vectors to high
address"), if necessary.

* Fix use of pmap_curmaxkvaddr.
* Use the PTP hint in the pmap.

Use vtopte() instead of pmap_pte().

* Rename PROCESS_PAGE_TBLS_BASE -> PTE_BASE
* Rename ALT_PAGE_TBLS_BASE -> APTE_BASE

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.

Fix the "va" argument to pmap_map_entry() when mapping kernel_ptpt.

Change pmap_map_entry() to work like pmap_map_chunk(): take a pointer
to the L1 table and a virtual address, and no pointer to the L2 table.
The L2 table will be looked up by pmap_map_entry(), which will panic
if the there is no L2 table for the requested VA.

NOTE: IT IS EXTREMELY IMPORTANT THAT THE CORRECT VIRTUAL ADDRESS
BE PROVIDED TO pmap_map_entry()! Notably, the code that mapped
the kernel L2 tables into the kernel PT mapping L2 table were not
passing actual virtual addresses, but rather offsets into the range
mapped by the L2 table. I have fixed up all of these call sites,
and tested the resulting kernel on both an IQ80310 and a Shark.
Other portmasters should examine their pmap_map_entry() calls if
their new kernels fail.

Keep track of which kernel PTs are available during bootstrap,
and let pmap_map_chunk() lookup the correct one to use for the
current VA. Eliminate the "l2table" argument to pmap_map_chunk().

Add a second L2 table for mapping kernel text/data/bss on the
IQ80310 (fixes booting kernels with ramdisks).

Always pass the L1 table to pmap_map_chunk(). This allows pmap_map_chunk()
to perform some error checking.

map_chunk() -> pmap_map_chunk(), and move it to pmap.c

map_pagetable() -> pmap_link_l2pt(), and move it to pmap.c

Collapse map_entry{,ro,nc}() into a single pmap_map_entry() that
takes a prot and a "cacheable" indicator.

Rename map_section() to pmap_map_section(), move it to pmap.c, and give it
an extra argument (prot - specifies protection of the mapping).

Forgot to remove the include file for the COMPAT_OLD_BOOTLOADER option i
removed.

_important_ : the old BtRiscBSD compatibility has been put to rest... this
means that kernels from now on are not bootable by !BtRiscBSD but only with
!BtNetBSD.

Big initial commit for a new cleaned up and extended bootblock style. This
patch also allows ELF symbol tables to be read when the patches on the
bootloader are commit but will work fine with the older bootloader.

An extra option `oldkernel' will be provided in the newer bootloader to
pass out old style bootconfig's thus enabling old style kernels to load and
function.

Tested on a.out and ELF (preliminary) kernels with both older and new style
bootconfig blocks.

We're not arm32 we're acorn32.

Oeps... boot_file was needed after all ... weird

Initial `machdep.booted_kernel' support as a string flag on the boot
arguments since otherwise RiscOS file names must be parsed.

Overhaul of the ARM cache code. This is mostly a simplification
pass. Rather than providing a whole slew of cache operations that
aren't ever used, distill them down to some useful primitives:

icache_sync_all Synchronize I-cache
icache_sync_range Synchronize I-cache range

dcache_wbinv_all Write-back and Invalidate D-cache
dcache_wbinv_range Write-back and Invalidate D-cache range
dcache_inv_range Invalidate D-cache range
dcache_wb_range Write-back D-cache range

idcache_wbinv_all Write-back and Invalidate D-cache,
Invalidate I-cache
idcache_wbinv_range Write-back and Invalidate D-cache,
Invalidate I-cache range

Note: This does not yet include an overhaul of the actual asm files
that implement the primitives. Instead, we've provided a safe default
for each CPU type, and the individual CPU types can now be optimized
one at a time.

Plus a handful of others that I'm familiar with. Lots of special-
purpose kernels should probably have this too but I'm not going
through all the arm, mips, and ppc evaluation board kernels to see
which ones are relevant.

Omitted from systems I know to be very small:
- sun2/GENERIC
- dreamcast/GENERIC
Feel free to remove it from others that need to be kept smaller.

Compile-tested a few of these just in case:
- alpha/GENERIC
- amd64/GENERIC
- evbmips/OCTEON
- i386/GENERIC
- riscv/GENERIC

UFS/LFS dirhash:
- Enable UFS_DIRHASH if the architecture or kernel model specific config
file can use 128MB of RAM or more.
- Remove experimental tag from UFS_DIRHASH; it's been with RUMP kernel
and by a number of NetBSD developers for years.
- Add LFS_DIRHASH if LFS was enabled.
- Be somewhat consistent with FS options order.

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)

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.

PR/34283: Gene ENonymous: Add IPFILTER_LOOKUP to the default kernel options
Also remove CCITT,NS,NIP

Now that boot32 can pass in a useful frame rate, it's reasonable to use the
standard video mode list in our example kernels, rather that a somewhat
random subset. So do that.

Finally remove the old, pre-wscons, acorn32 console code. This dated back
to RiscBSD and had been lurking in dark corners scaring people (mostly me)
for far too long. It will be missed, but not much, and I hope we can clear
up any fallout before 5.0.

While I'm in the area, also remove rpckbd(4), since pckbd(4) has
been supported on acorn32 for ages.

Xarm32VIDC has supported pckbd(4) for several releases now, so it's probably
safe to stop using rpckbd(4) in wscons configurations.

Update all kernel configs mentioning WSEMUL_* but not already including
WSDISPLAY_COMPAT_USL using the following rules:

- If INSTALL or obviously memory constrained, add WSDISPLAY_DEFAULTSCREENS=1
and commented out WSDISPLAY_COMPAT_USL
- Otherwise add WSDISPLAY_COMPAT_USL

Some of the INSTALL configs for larger memory machines are probably suitable
for adding WSDISPLAY_COMPAT_USL.

Now wsconscfg(8) should be able to switch VTs when expected.

The rnd pseudo-device is not really optional, because it is in the same
source file as the entropy-pool code itself. Move it to std. This
will be cleaned up more when I split the sources up as they should be.

This fixes build breaks on several ports. Thanks to Havard Eidnes for
pointing them out.
