installboot(8): formatting improvements

Use Ar foo instead of <foo>; this is mdoc.

Other formatting tweaks.
installboot(8): fix up markup

Don't overuse .Sy - when everything is highlighted, nothing is.  Use
.Ic for options &c to get correct PostScript output (both are bold in
plain text).

Use Aq Ar inside .Pa, as both Pa and Ar are rendered as underscored
text in plain text output, and the distinction is lost.

Don't set examples in bold, but give them .Pp space around - they are
much easier to read this way.

Use consistent -width in FILES.
document how to use installboot on netbsd/vax.

PR/57909: Jan-Benedict Glaw: Don't include (build) timestamp when doing a
reproducible build
fix usage string, improve error handling.
add missing chunk for repro-build. fix gcc warnings.
avoid stringop truncation, fix copyright string to prevent assembler warnings.

Fix build as a tool (Jan-Benedict Glaw)

Fix integer overflow of strtol(3) for "loadpoint" address on ILP32 hosts.

This strtol(3) was introduced in rev 1.12 for PR/57909 after netbsd-10,
but it returns LONG_MAX (0x7FFFFFFF) for 0xFFF00000 on ILP32 hosts and
the wrong loadpoint causes "NOT ENOUGH MEMORY" error by the BOOTROMs
on loading uboot.lif on (at least) my 9000/360 and 9000/425t.

Misc cosmetic changes for mostly readability.
- KNF and add some newlines per blocks
- define and use proper bintobcd() macro
- make local functions and variables static

The same uboot.lif binaries are generated.

Rename ${PROGAOUT} -> ${PROGELF} to reflect reality.
Use proper signedness for the LIF file system data structures.

Ancient 4.3BSD used short and int for location, file size, file type,
and addresses etc. but all of them should be unsigned.

Also rename several variables and add comments for readability.
The LIF file system info can be found in "The HPDir Project" page:
https://www.hp9845.net/9845/projects/hpdir/
The same uboot.lif binaries are generated.

Add a preliminary CD boot support to uboot for preparation of PR/54455.
Briefly tested on mame, but not enalbed yet.

Recognize SCSI CD-ROM devices as a booted device properly.

Necessary for PR port-hp300/54455, to boot an md root root RAMDISK

kernel from CD-ROM without "WARNING: can't find match for bootdev:"
prompt.

Sync with src/sys/arch/hp300/stand/mkboot/volhdr.h rev 1.6.
https://mail-index.netbsd.org/source-changes/2024/05/07/msg151195.html

Use proper signedness for the LIF file system data structures.
mkboot should use this MI <sys/bootblock.h> and volhdr.h should
be removed soon.

Use MI <sys/bootblock.h> to refer LIF filesystem structures.
This should have been done when LIF definitions were initially added
to <sys/bootblock.h> for MI installboot(8).

Enable SUPPORT_CD on uboot.

Make cd9660_util.c usable in userland tools like installboot(8).

This was partially done for src/distrib/cdrom/macppc_installboot,
but more strict prototypes are necessary for native binary builds.

Install cd9660 related system headers for tools installboot(8) builds.

Reorder function prototypes per source files.

Add cd9660 support to search a bootloader file in the target file system.

Also add CD boot support for hp300, using a bootloader file in cd9660 fs.
This is a tool's part to close PR/54455.

HP 9000/300 machines read LIF directory entry allocated after
the LIF volume header at the top of the boot disk during bootstrap,
and a bootstrap file must be contiguously allocated on the disk
due to limitation of the LIF specification.

Current NetBSD/hp300's bootloader is larger than ~80KB so we have
to prepare a special 'boot' partition for FFS (that has only 8KB (ffsv1)
or 32KB (ffsv2) spaces) disks to put such a large bootloader.

On the other hand, on ISO9660 fs all files are allocated contiguously
so we can specify a bootloader file in the target ISO9660 directly
in the LIF directory entry.

Note we can simply use the existing "append" option to create bootable
CD ISO for hp300, but it looks some emulators (at leaset MAME) reject
such non-standard ISO files, i.e. with an appended bootloader file at
the end of the image.

Put a RAMDISK kernel and SYS_UBOOT into hp300 installcd to make it bootable.

This should finally close PR/54455.

Fix tools build errors on Cygwin.

Appease warnings on building tools/installboot on Cygwin.

Largely unify the <machine/cpu.h> headers on the m68k platforms.

Consistently use "intr_depth" as the name of the interrupt depth counter
on m68k platforms.

Switch hp300 over to the common interrupt dispatch code.

XXX There are still some things to fix up here, but it's no worse
than it was before (the problems date back to when we flattened
the device interrupt levels into IPL_VM).

Switch hp300 over to the common m68k vector table.

Remove duplicated / slightly-tweaked loadustp() (load user segment table)
routines from all of the m68k ports using the shared pmap.  Instead, in
pmap_init(), set up a function pointer to the appropriate mmu_load_urp*()
function in mmu_subr.s.

TAB/space cleanup.

cpu_need_resched():

- Remove all code that should be MI, leaving the bare minimum under arch/.
- Make the required actions very explicit.
- Pass in LWP pointer for convenience.
- When a trap is required on another CPU, have the IPI set it locally.
- Expunge cpu_did_resched().

Refactor the 68040 writeback() from each m68k port's trap handler into a
shared copy: m68040_writeback().  It is essentially a copy of the Atari
version, with some minor cosmetic tweaks and one small performance optimization
from the mvme68k port.

Tested by rjs@ on a Quadra 950.  (Thanks!)

  - Remove unused *_NAMES macros for sysctl.
  - Remove unused *_MAXID for sysctls.
- Move CTL_MACHDEP sysctl definitions for m68k into m68k/include/cpu.h and
  use them on all m68k machines.

MAXADDR used for PA == VA mapping should be page size dependent.

Remove uarea swap-out functionality:

- Addresses the issue described in PR/38828.
- Some simplification in threading and sleepq subsystems.
- Eliminates pmap_collect() and, as a side note, allows pmap optimisations.
- Eliminates XS_CTL_DATA_ONSTACK in scsipi code.
- Avoids few scans on LWP list and thus potentially long holds of proc_lock.
- Cuts ~1.5k lines of code.  Reduces amd64 kernel size by ~4k.
- Removes __SWAP_BROKEN cases.

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

Rearrange process exit path to avoid need to free resources from different
process context ('reaper').

From within the exiting process context:
* deactivate pmap and free vmspace while we can still block
* introduce MD cpu_lwp_free() - this cleans all MD-specific context (such
  as FPU state), and is the last potentially blocking operation;
  all of cpu_wait(), and most of cpu_exit(), is now folded into cpu_lwp_free()
* process is now immediatelly marked as zombie and made available for pickup
  by parent; the remaining last lwp continues the exit as fully detached
* MI (rather than MD) code bumps uvmexp.swtch, cpu_exit() is now same
  for both 'process' and 'lwp' exit

uvm_lwp_exit() is modified to never block; the u-area memory is now
always just linked to the list of available u-areas. Introduce (blocking)
uvm_uarea_drain(), which is called to release the excessive u-area memory;
this is called by parent within wait4(), or by pagedaemon on memory shortage.
uvm_uarea_free() is now private function within uvm_glue.c.

MD process/lwp exit code now always calls lwp_exit2() immediatelly after
switching away from the exiting lwp.

g/c now unneeded routines and variables, including the reaper kernel thread

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

finish conversion to the common m68k cacheops:
add support for machine-specific flavors of the ops for off-chip caches.
many thanks to Izumi Tsutsui for his help with this.

merge the 12 copies of vm_machdep.c on the m68k platforms.
clean up some other stuff along the way, including:
 - use m68k/cacheops.*, remove duplicates from cpu.h.
 - centralize a few declarations in (all the copies of) cpu.h.
 - define M68K_VAC on platforms which have a VAC.
 - switch the sun platforms to the (now common) proc_trampoline().
 - do the phys_map thang on the sun platforms too, no reason not to.

Add a cpu_proc_fork(), called from uvm_proc_fork(), which takes care
of machine-dependent handling a fork() time (this is different from
forking the actual context in an LWP world).  #define it away on
platforms which do not need it.

Unification of the m68k syscall() function.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Make need_resched() take a "struct cpu_info *" argument.  This
causes gives a primitive form of processor affinity.  Its use in
roundrobin() still needs some work.

Sync w/ netbsd-1-5-base.

Add missing semicolon.

First sweep at scheduler state cleanup.  Collect MI scheduler
state into global and per-CPU scheduler state:

	- Global state: sched_qs (run queues), sched_whichqs (bitmap
	  of non-empty run queues), sched_slpque (sleep queues).
	  NOTE: These may collectively move into a struct schedstate
	  at some point in the future.

	- Per-CPU state, struct schedstate_percpu: spc_runtime
	  (time process on this CPU started running), spc_flags
	  (replaces struct proc's p_schedflags), and
	  spc_curpriority (usrpri of processes on this CPU).

	- Every platform must now supply a struct cpu_info and
	  a curcpu() macro.  Simplify existing cpu_info declarations
	  where appropriate.

	- All references to per-CPU scheduler state now made through
	  curcpu().  NOTE: this will likely be adjusted in the future
	  after further changes to struct proc are made.

Tested on i386 and Alpha.  Changes are mostly mechanical, but apologies
in advance if it doesn't compile on a particular platform.

Define cpu_number() as discussed on tech-smp.

synchronize types, and s/curproc/p/ in one forgotten place

mac68k part of pr 6152 fix, and missing bits for the others

Changes to support fork_kthread():
- cpu_set_kpc() now takes void *arg third argument, passed to the
  entry point.
- cpu_fork() allows parent to be non-curproc iff parent is proc0.
  When forking non-curproc, assume its state has already been saved.
- Adjust various pieces of machine-dependent code to account of all of this.

vm_offset_t -> {paddr_t,vaddr_t}, vm_size_t -> vsize_t

Avoid declaring the "astpending" and "want_resched" globals in cpu.h,
as this breaks C++ code that happens to indirectly include this header.
Both Matthias Scheler and I noticed this, independently.

This problem notably does not affect the atari and sun3/sun3x ports,
which have already implemented a similar solution.

Make these compile after m68k/m68k.h 1.4->1.5.

Update marc-pcmcia branch from trunk.

Move the prototype of hp300_calibrate_delay() to cpu.h

- Move a bunch of hp300 SPU-specific stuff out of cpu.h, and place it
  in new hp300spu.h file.  This includes the code that associates
  model number with cpu/mmu/cache combinations.
- Define "mmuid" constants for several models, derived from code
  provided by Mike Smith.

Rearrange the interrupt code slightly:
- place all interrupt-related macros, prototypes, etc. into <machine/intr.h>,
  like other ports.
- rename isrlink/isrunlink/isrinit, etc. intr_establish/intr_disestablish/
  intr_init, etc., and move to intr.c for naming consistency.
- don't call intr_init() twice.

regdump() is prototyped in m68k/cpu.h now.

Add prototypes as appropriate.

Prototypes for functions in locore.s and machdep.c (oops, forgot to
check this in the other day...)

Use <m68k/cpu.h>.

remove the now unused MHz constants, add a declaration for vectab[],
and document some globals.

doboot() takes no arguments (from Thorsten Frueauf)

Prototype doboot() and give it the __noreturn__ attribute, so that
machdep.c will compile.

Remove deprecated cpu_setstack().

Rather than using individual HP300 model names, map those model names to
properties such as "M68040" and "M68K_MMU_MOTOROLA", used to conditionally
compile code.  This is more in-line with now the other m68k ports do it,
and makes it much easier to find "common ground" among them.

In locore.s, use the MMU-type constants defined my <machine/cpu.h> rather
than "expanded" values.

Because HP300-model names are mapped to CPU/MMU combinations in
<machine/cpu.h>, no change to kernel configuration will be necessary.

remove unused cpu_exec() definitions.  moved "broken swap" markers, for
ports that still need it, to types.h.

Eliminate the double mapping of the kernel stack.  Enable swapping.

define BROKEN_SWAP and/or cpu_swapout as appropriate.

- added sunos_machdep.c for sun3, atari, amiga and mac68k.
- changed machdep.c and trap.c to use struct emul.
- remove ep_setup references.
- added struct emul to all emulations.
