Remove uscanner(4) driver

This exists for compatibility with a Linux interface which was apparently
deprecated in Linux 2.6. There are various mailing list threads going
back to 2004 where the usefulness of this driver is discussed, but
the conclusion is that scanner software has all moved to using ugen(4)
instead, and enabling this driver will not help you scan things.

Remove uyap, USB YAP phone firmware loader.

And the associated ezload EZ-USB code, which is only used by uyap.
It could theoretically be used by other drivers, but none of them are

Enable modules

remove urio(4), a driver for the Rio500 MP3 player.

At this point it is highly unlikely this 1999 device still has users,
but it still comes up in the context of maxv's USB-fuzzing (and any device
could pretend to be a urio(4)), so it's best to get rid of it.

Renamed all major entries to obsolete, as was done in previous removals.

This still requires an update to sanitizers, but they're located in
"external", perhaps it should be first committed upstream?

Proposed on tech-kern a month ago.

Retire "le* at pci?" from the shipped kernel configs:
- If the config had both an le@pci and a pcn, simply remove le@pci
(pcn would match at a higher priority anyway).
- If the config had le@pci enabled, but no pcn, change le@pci to pcn.
- If the config had le@pci commented out, but no pcn, change le@pci
to pcn and leave it commented out.

The pcn driver supports more chips than le@pci and does DMA directly
to/from mbufs rather than memory copies.

Remove FDDI support.

Remove HIPPI support and the esh(4) driver that uses it. There have not
been any users of HIPPI for some time, and it is unlikely to be resurrected.

UFS_EXTATTR_AUTOSTART was replaced by mount -o extattr

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)

Missing midi attachment.

Catch up with "Refactor in_cksum/in4_cksum/in6_cksum implementations".

Hi Joerg.

Refactor in_cksum/in4_cksum/in6_cksum implementations:
- All three functions are included in the kernel by default.
They call a backend function cpu_in_cksum after possibly
computing the checksum of the pseudo header.
- cpu_in_cksum is the core to implement the one-complement sum.
The default implementation is moderate fast on most platforms
and provides a 32bit accumulator with 16bit addends for L32 platforms
and a 64bit accumulator with 32bit addends for L64 platforms.
It handles edge cases like very large mbuf chains (could happen with
native IPv6 in the future) and provides a good base for new native
implementations.
- Modify i386 and amd64 assembly to use the new interface.

This disables the MD implementations on !x86 until the conversion is
done. For Alpha, the portable version is faster.

Remove COMPAT_HPUX.

Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark

Simplify and make extensible the config_search() / config_found() /

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an

Revert changes from previous that have nothing to do with STI PCI ROM
grovelling.

Fixes the build.

move the STI PCI ROM grovelling code into sti_pci_machdep.c instead of each
driver having its own copy

drop unnecessary wait and register write when moving the cursor sprite

drop the rectfill workaround here as well

set things up even if we're not the console

gftfb(4): Nix trailing whitespace.

more magic number reduction, the way colour map and cursor bitmap acess works
should be obvious now

magic number reduction, consistently use buffer 0

fix tpyo, now we can actually map registers from userland

use HW to draw bitmap fonts

use wrappers for bus_space_*() - makes things shorter, less annoying to read
and reduces unnecessary differences to hyperfb

as suspected the Visualize EG's rectangle fill function works exactly the same
as HCRX's, so apply the same trick to draw less than 32 pixel wide rectangles
and get rid of the workaround

properly return status info in ioctl(WSDISPLAYIO_GVIDEO)

allow mapping of blitter registers

make gftfb_restore_palette() grab the default colour map from rasops instead
of just writing the driver's map into the hardware ( which may have been
modified by the likes of wsfb )
With this we get a readable console even when exiting X in a less than
graceful manner.

For some reason the drawing engine occasionally scribbles past the right
boundary when filling rectangles, especially annoying when we draw whitespaces
As a workaround we draw all rectangles less than 50 pixels wide by drawing
a 50 pixel rectangle into off-screen memory to the right of the visible fb and
then copy the portion we want. Keeps track of the colour and size of the
off-screen rectangle so we can avoid redrawing it whenever possible.

fix brainfart - only update fbi_fbsize, not the size of the visible fb...

in gftfb_ioctl():
- identify ourselves as WSDISPLAY_TYPE_STI
- return full fb geometry in WSDISPLAYIO_GET_FBINFO

if the framebuffer is wider than the visible area, use the full width for the
glyphcache

support WSDISPLAYIO_SVIDEO so X can turn the monitor off
so far I only know how to turn off video output, not sync(s). Better than
nothing though.

add hardware cursor support, mostly for X

avoid one more instance of unnecessary blitter stalling

keep track of hw settings for blitter, fill of fb access to avoid unnecessary
register writes
while there, remove some accidentially left in debug goop

play the same lazy cursor (un)draw trick as cgsix and friends
visible speedup in things like systat

enable glyph cache, anti-aliased fonts etc.

blitter time!
everything except drawing characters i now done by hardware
next step - glyphcache

crude beginning of a native driver for PCI Visualize EG cards
so far it supports:
- colour
- virtual consoles
todo:
- mmap
- hardware acceleration
- STI refactoring

use BINC writes to draw characters instead of abusing the rectangle primitive
small but measurable speedup, fewer register writes, and we demonstrate how
to use BINC

use de-obfuscated register names where possible

hppa/dev: Nix trailing whitespace.

No functional change intended.

some cleanup:
- remove code to initialize a DAC that HCRX doesn't have
- decode / explain some more magic numbers
add more comments describing what we do and why

remove glyphcache and debug goop
we're not likely to be able to use any off-screen memory on this hardware, so
don't pretend we will.

now that we can draw rectangles in exactly the size we want without abusing
the pixel mask, we no longer need to draw characters in two passes - just
disable transparency, set fore- and background, and go.
Only clear the character cell when drawing blanks.

finally figured out how to automatically mask off pixels at the right when
drawing rectangles so we can drop the workaround

set things up even if we're not the console

fix tpyo, now we can actually map registers from userland

simplify putchar() a bit, use 16bit accesses for fonts that are more than 8
pixels wide

remove sc_putchar - don't need it anymore

now that we know how, draw characters by hardware

get rid of the workarounds to draw rectangles less than 32 pixels wide
turns out the hardware applies a bit mask to all rectangle fills, and we
can turn the background transparent. With that we just mask off the pixels
we don't need in the less than 32 pixels wide case.
Next step - figure out how to abuse that to draw characters
I bet Visualize EG works exactly the same way in that regard.

properly return status info in ioctl(WSDISPLAYIO_GVIDEO)

implement ioctl(GCID)

hyperfb(4): Nix trailing whitespace.

No functional change intended.

magic number reduction, NFC

do cursor position updated the way NGLE does - poke reg 28 and wait_fifo
instead of waiting for the whole thing to go idle

fix tpyo and properly limit what we can mmap()

hyperfb(4): Nix trailing whitespace, sprinkle KNF.

No functional change intended -- just whitespace (and comments).

use the blitter to draw small rectangles as well by abusing set/clear ops
and the plane mask

hand X a 24bit framebuffer if the hardware supports it

remove a bunch of #defines that have been moved to stireg.h

add cursor sprite support

we have a blitter - use it

first shot at a native driver for HCRX cards
this will give you a fully working wsdisplay in 8bit colour living in the
overlay planes, X/wsfb will also work.
No acceleration or cursor sprite support yet.

Rename NetBSD/hp700 to NetBSD/hppa.

Unfortunately our VCS isn't very helpful here.

Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int. The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER! Some subsystems have

#define min(a, b) ((a) < (b) ? (a) : (b))
#define max(a, b) ((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX. Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate. But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all. (Who knows, maybe in some cases integer
truncation is actually intended!)

more FX5/10 support:

- expose 8bit overlay on WSDISPLAYIO_MODE_MAPPED on FX5/10
with this we can run X with wsfb in 8bit with correct colours and hw cursor

don't dump registers in the middle of setting things up...

humble beginnings of FX5/10 support. This will:
- provide a working, accelerated console at least on my FX5
- ROPs and alpha blending don't work, so we use a putchar() based cursor()
and disable alpha fonts
- X11 can use a hw cursor and 24bit framebuffer, but since we don't know how
attributes work (yet) this will give us the blue channel piped through the
8bit palette. With a linear ramp that's at least somewhat usable.
Next steps:
- provide an 8bit fb with palette so we can run X in colour
- find the FX5's equivalent of the VISFX_FATTR register so we can either force
24bit colour or use proper WIDs

hppa/summitfb(4): Nix trailing whitespace.

Plus some other minor whitespace/comment cleanups.

some cleanup & optimization:
- don't write the pixel mask register for operations that don't use it
- track write mode, only wait if we change it
- always sync when switching in and out of fb mode ( for X... )
- drop sc_hwmode
... about 10% speedup and no more glitches when starting X

make sure we apply the pixel mask when drawing characters so we don't scribble
outside the character cell

now that we know how, use the blitter to:
- draw characters
- scroll
- rectangle fills
no ROP support yet, so the cursor is drawn using putchar
while there get rid of some unused cargo-culted goop from gftfb
MUCH faster now

CV: ----------------------------------------------------------------------

use summitreg.h

add hardware cursor support
while there remove debug goop, fix ioctl(GCID)

hppa/summitfb(4): Fix SUMMITFB_DEBUG build.

beginnings of a driver for Visualize FX graphics cards
So far it does:
- work on my FX4
- use the 8bit overlay, in R3G3B2
- all drawing by software, clear screen by hw
- X works in 8bit with wsfb

Use vmem(9) rather than extent(9) to manage IOMMU mappings.

Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

Make copystr() a MI C function, part of libkern and shared on all
architectures.

Notes:

- On alpha and ia64 the function is kept but gets renamed locally to avoid
symbol collision. This is because on these two arches, I am not sure
whether the ASM callers do not rely on fixed registers, so I prefer to
keep the ASM body for now.
- On Vax, only the symbol is removed, because the body is used from other
functions.
- On RISC-V, this change fixes a bug: copystr() was just a wrapper around
strlcpy(), but strlcpy() makes the operation less safe (strlen on the
source beyond its size).
- The kASan, kCSan and kMSan wrappers are removed, because now that
copystr() is in C, the compiler transformations are applied to it,
without the need for manual wrappers.

Could test on amd64 only, but should be fine.

Overhaul the API used to fetch and store individual memory cells in
userspace. The old fetch(9) and store(9) APIs (fubyte(), fuword(),
subyte(), suword(), etc.) are retired and replaced with new ufetch(9)
and ustore(9) APIs that can return proper error codes, etc. and are
implemented consistently across all platforms. The interrupt-safe
variants are no longer supported (and several of the existing attempts
at fuswintr(), etc. were buggy and not actually interrupt-safe).

Also augmement the ucas(9) API, making it consistently available on
all plaforms, supporting uniprocessor and multiprocessor systems, even
those that do not have CAS or LL/SC primitives.

The size is set for all the writes, but some of the arch-specific reads

The amd64 (and i386) need variable sized fp register save areas in order

These functions are rarely called - so the extra argument won't matter.

Change the type of the 'cookie' that holds the state of the core dump file

Remove pfind() and pgfind(), fix locking in various broken uses of these.
Rename real routines to proc_find() and pgrp_find(), remove PFIND_* flags
and have consistent behaviour. Provide proc_find_raw() for special cases.
Fix memory leak in sysctl_proc_corename().

COMPAT_LINUX: rework ptrace() locking, minimise differences between
different versions per-arch.

Note: while this change adds some formal cosmetics for COMPAT_DARWIN and
COMPAT_IRIX - locking there is utterly broken (for ages).

Fixes PR/43176.

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.

Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on
acorn26 (thanks to <bjh21>).

Fix kernel profiling on HPPA.

- stop gcc emitting stuff that HPUX requires
- don't use splhigh() in MCOUNT_ENTER as a call to _mcount will be
generated at the moment. Disable interrupts in hardware instead.
- Fix _PROF_PROLOGUE to save/restore all the register args when calling
_mcount.
- Fixup LEAF_ENTRY to dtrt (I think) in the GPROF case.
- Provide LEAF_ENTRY_NOPROFILE and sprinkle its use where i) profiling
causes problems, e.g. trap handlers, and ii) where it just doesn't
make sense, e.g. start.

Some fixes for QEMU/hppa.

Don't call desidhash_l on pcxl2 as it doesn't support it. QEMU emulates
this cpu and would trap on illegal instruction for the diag in desidhash_l

Allow a FPU to be missing... more fixes are likely here.

Various #include fixes and review by matt@.

Misc KNF.

The FP regs are accessed in both physical and virtual modes. Make sure
they're allocated in directly mapped memory to avoid aliasing problems
and unnecessary cache flushing.

Fix various names and references. If we ever directly map the uarea and
pcb we can change things at that point.
