e9e0512210 Remove five now unused fields from struct cdevsw. They should never
have been there in the first place.  A GENERIC kernel shrinks almost 1k.

a2c68c62db This patch clears the way for removing a number of tty related
fields in struct cdevsw:

        d_stop          moved to struct tty.
        d_reset         already unused.
        d_devtotty      linkage now provided by dev_t->si_tty.

These fields will be removed from struct cdevsw together with
d_params and d_maxio Real Soon Now.

The changes in this patch consist of:

        initialize dev->si_tty in *_open()
        initialize tty->t_stop
        remove devtotty functions
        rename ttpoll to ttypoll
        a few adjustments to these changes in the generic code

d612df1de6 Remove NBPF conditionality of bpf calls in most of our network drivers.
This means that we will not have to have a bpf and a non-bpf version
of our driver modules.

This does not open any security hole, because the bpf core isn't loadable

The drivers left unchanged are the "cross platform" drivers where the respective
maintainers are urged to DTRT, whatever that may be.

Add a couple of missing FreeBSD tags.

2817a59f50 Back out a portion of the last commit. DFLTPHYS and MAXPHYS cannot
be set by a kernel conf option due to the struct buf structural
    dependancy (sizing of b_pages[]) creating a conflict with modules
    (which are not compiled with kernel config options overrides).

    We'll be able to sysctl these two later on when the buffer subsystem
    is revamped.

e8761b4e05 Fix bug in pipe code relating to writes of mmap'd but illegal address
spaces which cross a segment boundry in the page table.  pmap_kextract()
    is not designed for access to the user space portion of the page
    table and cannot handle the null-page-directory-entry case.

    The fix is to have vm_fault_quick() return a success or failure which
    is then used to avoid calling pmap_kextract().

6dd370e71b Pull in the core bus drivers based on the machine type rather than
requiring the user to figure it out.  So, if you comment out all but the
machine type you are using, you automatically get the bus code just for
your system.  (eg DEC_EB164 implies cia, etc).  Multiple machine types
still pulls in the appropriate busses.  This means, take things like
'controller cia0' out of your config.

d963135a0b This commit adds driver support for PCI fast ethernet NICs based on
the Davicom DM9100 and DM9102 chipsets, including the Jaton Corporation
XPressNet. Datasheet is available from www.davicom8.com.

The DM910x chips are still more tulip clones. The API is reproduced
pretty faithfully, unfortunately the performance is pretty bad. The
transmitter seems to have a lot of problems DMAing multi-fragment
packets. The only way to make it work reliably is to coalesce transmitted
packets into a single contiguous buffer. The Linux driver (written by
Davicom) actually does something similar to this. I can't recomment this
NIC as anything more than a "connectivity solution."

This driver uses newbus and miibus and is supported on both i386
and alpha platforms.

3489469f10 This commit adds driver support for the Silicon Integrated Systems
SiS 900 and SiS 7016 PCI fast ethernet chipsets. Full manuals for the
SiS chips can be found at www.sis.com.tw.

This is a fairly simple chipset. The receiver uses a 128-bit multicast
hash table and single perfect entry for the station address. Transmit and
receive DMA and FIFO thresholds are easily tuneable. Documentation is
pretty decent and performance is not bad, even on my crufty 486. This
driver uses newbus and miibus and is supported on both the i386 and
alpha architectures.

than looking for a non-zero value in a4, as *BSD & OSF/1 do.

db4fdbd041 This commit adds device driver support for the Sundance Technologies ST201
PCI fast ethernet controller. Currently, the only card I know that uses
this chip is the D-Link DFE-550TX. (Don't ask me where to buy these: the
only cards I have are samples sent to me by D-Link.)

This driver is the first to make use of the miibus code once I'm sure
it all works together nicely, I'll start converting the other drivers.

The Sundance chip is a clone of the 3Com 3c90x Etherlink XL design
only with its own register layout. Support is provided for ifmedia,
hardware multicast filtering, bridging and promiscuous mode.

c1329f8c5d Major rewrite.
The first reason for this rewrite is KNF conformance.

The second reason is to avoid redundancy. Each function printed the same
string, with only the syscall name being different. The actual printing is now
performed by a single function, which gets the syscall name as an argument.

The third reason is that of convenience. It's now very easy to add a new
dummy implementation. Just add ``DUMMY(foo);'' to the file. It's also a lot
easier now to see if a syscall has a dummy implementation or not.

The dummies are ordered on syscall number. Please maintain this when adding
new dummies (there're 32 candidates at the time of writing :-)

Provide bus_print_child_header() and bus_print_child_footer()

These functions should be used whenever possible (unless you can
just use bus_generic_print_child())

The BUS_PRINT_CHILD method now returns int instead of void.

Modify everything else that defines or uses a BUS_PRINT_CHILD
method to comply with the above changes.

	- Devices are 'on' a bus, not 'at' it.
	- If a custom BUS_PRINT_CHILD method does the same thing

97307ab479 This commit adds device driver support for Adaptec Duralink PCI fast
ethernet controllers based on the AIC-6915 "Starfire" controller chip.
There are single port, dual port and quad port cards, plus one 100baseFX
card. All are 64-bit PCI devices, except one single port model.

The Starfire would be a very nice chip were it not for the fact that
receive buffers have to be longword aligned. This requires buffer
copying in order to achieve proper payload alignment on the alpha.
Payload alignment is enforced on both the alpha and x86 platforms.
The Starfire has several different DMA descriptor formats and transfer
mechanisms. This driver uses frame descriptors for transmission which
can address up to 14 packet fragments, and a single fragment descriptor
for receive. It also uses the producer/consumer model and completion
queues for both transmit and receive. The transmit ring has 128
descriptors and the receive ring has 256.

This driver supports both FreeBSD/i386 and FreeBSD/alpha, and uses newbus
so that it can be compiled as a loadable kernel module. Support for BPF
and hardware multicast filtering is included.

subsequent use causes a failure.

The fix is (1) to clear p_vmspace early, to stop pmap_growkernel
from stomping on memory, and (2) to defer part of the initialization
of new page directories until p_vmspace is initialized.

52ea4270f3 These changes appear to give us benefits with both small (32MB) and
large (1G) memory machine configurations.  I was able to run 'dbench 32'
on a 32MB system without bring the machine to a grinding halt.

    * buffer cache hash table now dynamically allocated.  This will
      have no effect on memory consumption for smaller systems and
      will help scale the buffer cache for larger systems.

    * minor enhancement to pmap_clearbit().  I noticed that
      all the calls to it used constant arguments.  Making
      it an inline allows the constants to propogate to
      deeper inlines and should produce better code.

    * removal of inherent vfs_ioopt support through the emplacement
      of appropriate #ifdef's, with John's permission.  If we do not
      find a use for it by the end of the year we will remove it entirely.

    * removal of getnewbufloops* counters & sysctl's - no longer
      necessary for debugging, getnewbuf() is now optimal.

    * buffer hash table functions removed from sys/buf.h and localized
      to vfs_bio.c

    * VFS_BIO_NEED_DIRTYFLUSH flag and support code added
      ( bwillwrite() ), allowing processes to block when too many dirty
      buffers are present in the system.

    * removal of a softdep test in bdwrite() that is no longer necessary
      now that bdwrite() no longer attempts to flush dirty buffers.

    * slight optimization added to bqrelse() - there is no reason
      to test for available buffer space on B_DELWRI buffers.

    * addition of reverse-scanning code to vfs_bio_awrite().
      vfs_bio_awrite() will attempt to locate clusterable areas
      in both the forward and reverse direction relative to the
      offset of the buffer passed to it.  This will probably not
      make much of a difference now, but I believe we will start
      to rely on it heavily in the future if we decide to shift
      some of the burden of the clustering closer to the actual
      I/O initiation.

    * Removal of the newbufcnt and lastnewbuf counters that Kirk
      added.  They do not fix any race conditions that haven't already
      been fixed by the gbincore() test done after the only call
      to getnewbuf().  getnewbuf() is a static, so there is no chance
      of it being misused by other modules.  ( Unless Kirk can think
      of a specific thing that this code fixes.  I went through it
      very carefully and didn't see anything ).

    * removal of VOP_ISLOCKED() check in flushbufqueues().  I do not
      think this check is necessary, the buffer should flush properly
      whether the vnode is locked or not. ( yes? ).

    * removal of extra arguments passed to getnewbuf() that are not
      necessary.

    * missed cluster_wbuild() that had to be a cluster_wbuild_wb() in
      vfs_cluster.c

    * vn_write() now calls bwillwrite() *PRIOR* to locking the vnode,
      which should greatly aid flushing operations in heavy load
      situations - both the pageout and update daemons will be able
      to operate more efficiently.

    * removal of b_usecount.  We may add it back in later but for now
      it is useless.  Prior implementations of the buffer cache never
      had enough buffers for it to be useful, and current implementations
      which make more buffers available might not benefit relative to
      the amount of sophistication required to implement a b_usecount.
      Straight LRU should work just as well, especially when most things
      are VMIO backed.  I expect that (even though John will not like
      this assumption) directories will become VMIO backed some point soon.

If machine/bus.h is included, but neither bus_memio.h nor bus_pio.h

This won't change existing drivers, all of which include one or more
of bus_{p,mem}io.h, but will allow drivers from other systems to come
over with fewer changes.  I freely admit that this might not be
optimal for some drivers, but those drivers can be optimized for
FreeBSD after the initial bringup happens.

Without the change, there is a bug that preclude drivers from
compiling with strange warning/errors.

I've been running this here for a while now w/o ill effects.

6cb5fe6c6b Slight reorganization of kernel thread/process creation. Instead of using
SYSINIT_KT() etc (which is a static, compile-time procedure), use a
NetBSD-style kthread_create() interface.  kproc_start is still available
as a SYSINIT() hook.  This allowed simplification of chunks of the
sysinit code in the process.  This kthread_create() is our old kproc_start
internals, with the SYSINIT_KT fork hooks grafted in and tweaked to work
the same as the NetBSD one.

One thing I'd like to do shortly is get rid of nfsiod as a user initiated
process.  It makes sense for the nfs client code to create them on the
fly as needed up to a user settable limit.  This means that nfsiod
doesn't need to be in /sbin and is always "available".  This is a fair bit
easier to do outside of the SYSINIT_KT() framework.

4f4eb0cfe5 The second phase of syscons reorganization.
- Split syscons source code into manageable chunks and reorganize
  some of complicated functions.

- Many static variables are moved to the softc structure.

- Added a new key function, PREV.  When this key is pressed, the vty
  immediately before the current vty will become foreground.  Analogue
  to PREV, which is usually assigned to the PrntScrn key.
  PR: kern/10113
  Submitted by: Christian Weisgerber <naddy@mips.rhein-neckar.de>

- Modified the kernel console input function sccngetc() so that it
  handles function keys properly.

- Reorganized the screen update routine.

- VT switching code is reorganized.  It now should be slightly more
  robust than before.

- Added the DEVICE_RESUME function so that syscons no longer hooks the
  APM resume event directly.

- New kernel configuration options: SC_NO_CUTPASTE, SC_NO_FONT_LOADING,
  SC_NO_HISTORY and SC_NO_SYSMOUSE.
  Various parts of syscons can be omitted so that the kernel size is
  reduced.

  SC_PIXEL_MODE
  Made the VESA 800x600 mode an option, rather than a standard part of
  syscons.

  SC_DISABLE_DDBKEY
  Disables the `debug' key combination.

  SC_ALT_MOUSE_IMAGE

  console, rather than drawing an arrow on the screen.

  14-line and 8-line font data will be compiled in.  This option replaces

- The VGA driver is split into /sys/dev/fb/vga.c and /sys/isa/vga_isa.c.

- The video driver provides a set of ioctl commands to manipulate the
  frame buffer.

- New kernel configuration option: VGA_WIDTH90
  Enables 90 column modes: 90x25, 90x30, 90x43, 90x50, 90x60.  These
  modes are mot always supported by the video card.

  split into sys/fbio.h, sys/kbio.h (a new file) and sys/consio.h
  (another new file).  machine/console.h is still maintained for
  compatibility reasons.

- Kernel console selection/installation routines are fixed and
  slightly rebumped so that it should now be possible to switch between
  the interanl kernel console (sc or vt) and a remote kernel console
  (sio) again, as it was in 2.x, 3.0 and 3.1.

- Screen savers and splash screen decoders

  savers and splash screen decoders are slightly modified.  After this
  update, /sys/modules/syscons/saver.h is no longer necessary and is
  removed.

3f78b53e89 I'm sick of the automatic rename of /kernel to /kernel.old while doing
development that leads to lots of crashes during boot.

I have made a 'reinstall' target (like in ports, and reinstall.debug)
This is most useful if you want to keep /kernel.old as a known bootable
kernel.  If you test a new kernel and have to reboot for a fix, a
'make reinstall' will install the new kernel over the top of the old
non-viable one, leaving the old one untouched.  This is mainly meant
for development, not general users.

087d4857e5 Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition.  eisa, isapnp and pccard* are
not yet using the new resource manager.  Once fully converted, all drivers
will be loadable, including PCI and ISA.

(Some other changes appear to have snuck in, including a port of Soren's
 ATA driver to the Alpha.  Soren, back this out if you need to.)

This is a checkpoint of work-in-progress, but is quite functional.

23a589f45b 1. Modify config to issue different code for debugging.
2.  Config complains if you use -g:

    Debugging is enabled by default, there is no ned to specify the -g option

3.  Config warns you if you don't use -s:

    Building kernel with full debugging symbols.  Do
    "config -s BSD" for historic partial symbolic support.
    To install the debugging kernel, do make install.debug

    (BSD was the name of the config file I used; I print out the same

fa78fd775b Make the xl and pn drivers work on FreeBSD/alpha and add them to
sys/alpha/conf/GENERIC.

Note: the PNIC ignores the lower few bits of the RX buffer DMA address,
which means we have to add yet another kludge to make it happy. Since
we can't offset the packet data, we copy the first few bytes of the
received data into a separate mbuf with proper alignment. This puts
the IP header where it needs to be to prevent unaligned accesses.

Also modified the PNIC driver to use a non-interrupt driven TX
strategy. This improves performance somewhat on x86/SMP systems where
interrupt delivery doesn't seem to be as fast with an SMP kernel as
with a UP kernel.

1c67fa8f3d Keyboard driver update in preparation for the USB keyboard driver.
- Refined internal interface in keyboard drivers so that:
  1. the side effect of device probe is kept minimal,
  2. polling mode function is added,
  3. and new ioctl and configuration options are added (see below).

- Added new ioctl: KDSETREPEAT
  Set keyboard typematic rate.  There has existed an ioctl command,
  KDSETRAD, for the same purpose.  However, KDSETRAD is dependent on
  the AT keyboard.  KDSETREPEAT provides more generic interface.
  KDSETRAD will still be supported in the atkbd driver.

  (There has been undocumented options, DKKEYMAP, UKKEYMAP, GRKEYMAP,
  SWKEYMAP, RUKEYMAP, ESKEYMAP, and ISKEYMAP to set the default keymap.

It is now clear that the timestamp is always valid in fork_trampoline()

can only happen if there are multiple cpus, so don't check or set

b7a0b99c31 Rip out PQ_ZERO queue. PQ_ZERO functionality is now combined in with
PQ_FREE.  There is little operational difference other then the kernel
    being a few kilobytes smaller and the code being more readable.

    * vm_page_select_free() has been *greatly* simplified.
    * The PQ_ZERO page queue and supporting structures have been removed
    * vm_page_zero_idle() revamped (see below)

    PG_ZERO setting and clearing has been migrated from vm_page_alloc()
    to vm_page_free[_zero]() and will eventually be guarenteed to remain
    tracked throughout a page's life ( if it isn't already ).

    When a page is freed, PG_ZERO pages are appended to the appropriate
    tailq in the PQ_FREE queue while non-PG_ZERO pages are prepended.
    When locating a new free page, PG_ZERO selection operates from within
    vm_page_list_find() ( get page from end of queue instead of beginning
    of queue ) and then only occurs in the nominal critical path case.  If
    the nominal case misses, both normal and zero-page allocation devolves
    into the same _vm_page_list_find() select code without any specific
    zero-page optimizations.

    Additionally, vm_page_zero_idle() has been revamped.  Hysteresis has been
    added and zero-page tracking adjusted to conform with the other changes.
    Currently hysteresis is set at 1/3 (lo) and 1/2 (hi) the number of free
    pages.  We may wish to increase both parameters as time permits.  The
    hysteresis is designed to avoid silly zeroing in borderline allocation/free
    situations.

bbafa43d0d Change the load address of the ELF dynamic linker from "2L*MAXDSIZ"
to an architecture-specific value defined in <machine/elf.h>.  This
solves problems on large-memory systems that have a high value for
MAXDSIZ.

The load address is controlled by a new macro ELF_RTLD_ADDR(vmspace).
On the i386 it is hard-wired to 0x08000000, which is the standard
SVR4 location for the dynamic linker.

On the Alpha, the dynamic linker is loaded MAXDSIZ bytes beyond
the start of the program's data segment.  This is the same place
a userland mmap(0, ...) call would put it, so it ends up just below
all the shared libraries.  The rationale behind the calculation is
that it allows room for the data segment to grow to its maximum
possible size.

These changes have been tested on the i386 for several months
without problems.  They have been tested on the Alpha as well,
though not for nearly as long.  I would like to merge the changes
into 3.1 within a week if no problems have surfaced as a result of
them.

4b7738dba1 Mostly remove the VM_STACK OPTION.
This changes the definitions of a few items so that structures are the
same whether or not the option itself is enabled. This allows
people to enable and disable the option without recompilng the world.

As the author says:

|I ran into a problem pulling out the VM_STACK option.  I was aware of this
|when I first did the work, but then forgot about it.  The VM_STACK stuff
|has some code changes in the i386 branch.  There need to be corresponding
|changes in the alpha branch before it can come out completely.

what is done:
|
|1) Pull the VM_STACK option out of the header files it appears in.  This
|really shouldn't affect anything that executes with or without the rest
|of the VM_STACK patches.  The vm_map_entry will then always have one
|extra element (avail_ssize).  It just won't be used if the VM_STACK
|option is not turned on.
|
|I've also pulled the option out of vm_map.c.  This shouldn't harm anything,
|since the routines that are enabled as a result are not called unless
|the VM_STACK option is enabled elsewhere.
|
|2) Add what appears to be appropriate code the the alpha branch, still
|protected behind the VM_STACK switch.  I don't have an alpha machine,
|so we would need to get some testers with alpha machines to try it out.
|
|Once there is some testing, we can consider making the change permanent
|for both i386 and alpha.
|
[..]
|
|Once the alpha code is adequately tested, we can pull VM_STACK out
|everywhere.

f6d935dae9 Reserve a major number for use by the Iprobe device driver.
Iprobe is an alpha-only system profiling suite which I'm porting from
Linux/alpha to FreeBSD.

Iprobe works by using the hardware profiling support built into
alpha cpus.  In a nutshell,  what Iprobe does is to setup the alpha
performance counters to sample the pc at a fairly high rate & dumps
those pc samples out to user space.  Then some code runs to map the
sampled PCs to functions.  You get a bit more than that (like the PSL
word, so you can tell if you're in the kernel or userland, what the
ipl is, etc).

8f01fff32f Implement 'software completion' for floating point arithmetic. On the
alpha, operations involving non-finite numbers or denormalised numbers
or operations which should generate such numbers will cause an arithmetic
exception.  For programs which follow some strict code generation rules,
the kernel trap handler can then 'complete' the operation by emulating
the faulting instruction.

To use software completion, a program must be compiled with the arguments
'-mtrap-precision=i' and '-mfp-trap-mode=su' or '-mfp-trap-mode=sui'.
Programs compiled in this way can use non-finite and denormalised numbers
at the expense of slightly less efficient code generation of floating
point instructions.  Programs not compiled with these options will receive
a SIGFPE signal when non-finite or denormalised numbers are used or
generated.

truncated to 32 bits.
* Change the calling convention of the device mmap entry point to

  devices with a larger memory map than (1<<32) to be supported
  on the alpha (/dev/mem is one such).

These changes are required to allow the X server to mmap the various
I/O regions used for device port and memory access on the alpha.

a6df719969 Initial attempt to update the Alpha loader and kernel to use the machine
independent elf loader and have access to kld modules.  Jordan and I were
not sure how to create boot floppies, and the things we tried just made
SRM laugh in our faces - but it was upset at boot1 which was not touched
by these changes.  Essentially this has been untested. :-(

What this does is to steal the last three slots from the nine spare longs
in the bootinfo_v1 struct to pass the module base pointer through.

The startup code now to set up and fills in the module and environment
structures, hopefully close enough to the i386 layout to be able to use
the same kernel code.  We now pass though the updated end of the kernel
space used, rather than _end. (like the i386).

If this does not work, it needs to be beaten into shape pronto.  Otherwise
it should be backed out before 3.0.

saver and splash screen can all work properly with syscons.  Note that
the splash screen option (SC_SPLASH_SCREEN) does not work yet, as it
requires additional code from msmith.

- Reorganized the splash screen code to match the latest development
  in this area.
- Delay screen switch in `switch_scr()' until the screen saver is
  stopped, if one is running,
- Start the screen saver immediately, if any, when the `saver' key is
  pressed. (There will be another commit for `kbdcontrol' to support
  this keyword in the keymap file.)
- Do not always stop the screen saver when mouse-related ioctls
  are called.  Stop it only if the mouse is moved or buttons are
  clicked; don't stop it if any other mouse ioctls are called.

2. Added provision to write userland screen savers.  (Contact me if you
are interested in writing one.)

- Added CONS_IDLE, CONS_SAVERMODE, and CONS_SAVERSTART ioctls to
  support userland screen savers.

    The patch supports using the X10 Mouse Remote in both stand-alone and
pass-through configurations, so you can plug your mouse and remote into the
same serial port, use the mouse for X, and use the remote for other apps
like Fxtv. For instance, we can now control fxtv via the remote control
just like a TV : change channels, mute, increase volume, zoom video,
freeze frame 8)

     The mouse events are channeled through the syscons/sysmouse I/F like
normal, and the remote buttons are "syphoned off" to a UNIX-domain stream
socket (defined as _PATH_MOUSEREMOTE in <machine/mouse.h>) for a
remote-aware app to grab and use.

For further info on the X10 Mouse Remote see:

037452c745 [Add missing files from previous commit]
Major changes to the generic device framework for FreeBSD/alpha:

* Eliminate bus_t and make it possible for all devices to have
  attached children.

* Support dynamically extendable interfaces for drivers to replace
  both the function pointers in driver_t and bus_ops_t (which has been
  removed entirely.  Two system defined interfaces have been defined,
  'device' which is mandatory for all devices and 'bus' which is
  recommended for all devices which support attached children.

* In addition, the alpha port defines two simple interfaces 'clock'
  for attaching various real time clocks to the system and 'mcclock'
  for the many different variations of mc146818 clocks which can be
  attached to different alpha platforms.  This eliminates two more
  function pointer tables in favour of the generic method dispatch
  system provided by the device framework.

Future device interfaces may include:

* cdev and bdev interfaces for devfs to use in replacement for specfs
  and the fixed interfaces bdevsw and cdevsw.

* scsi interface to replace struct scsi_adapter (not sure how this
  works in CAM but I imagine there is something similar there).

* various tailored interfaces for different bus types such as pci,
  isa, pccard etc.

3ed12c01d2 Added accent (dead) key support to syscons and kbdcontrol.
With a keymap with accent key definitions loaded to syscons, you press
an accent key followed by a regular letter key to produce an accented
letter.  Press an accent key followed by the space bar to get the
accent letter itself.

Code is based on the ideas and work by jmrueda@diatel.upm.es and
totii@est.is.

PR: i386/4016

console.h
- Defined structures and constants for accent (dead) keys.

syscons.c, kbdtables.h
- When an accent key is pressed, set the corresponding index to
  `accents'.  If the next key is the space key, produce the accent char
  itself.  Otherwise search the accent key map entry, indexed by
  `accents', for a matching pair of a regular char and an accented char.
- Added ioctl functions to set and get the accent key map (PIO_DEADKEYMAP
  and GIO_DEADKEYMAP).

14e5988fe7 - Add support for the following mice to psm/moused/sysmouse:
MS IntelliMouse, Kensington Thinking Mouse, Genius NetScroll,
  Genius NetMouse, Genius NetMouse Pro, ALPS GlidePoint, ASCII
  MieMouse, Logitech MouseMan+, FirstMouse+

- The `psm' driver is made to recognize various models of PS/2 mice
and enable their extra features so that their additional buttons and
wheel/roller are recognized. The name of the detected model will be
printed at boot time.

- A set of new ioctl functions are added to the `psm', `mse' and
`sysmouse' drivers so that the userland program (such as the X server)
can query device information and change driver settings.

- The wheel/roller movement is handled as the `Z' axis movement by the
mouse drivers and the moused daemon. The Z axis movement may be mapped
to another axis movement or buttons.

- The mouse drivers support a new, standard mouse data format,
MOUSE_PROTO_SYSMOUSE format which can encode x, y, and x axis movement
and up to 10 buttons.

/sys/i386/include/mouse.h
- Added some fields to `mousestatus_t' to store Z axis movement
  and flag bits.
- Added the field `model' to `mousehw_t' to store mouse model code.
  Defined model codes.
- Extended `mousemode_t'.
- Added new protocols and some constants for them.
- Added new ioctl functions and structures.
- Removed obsolete ioctl definitions.

/sys/i386/include/console.h
- Added `dz' field to the structure `mouse_data' to pass Z axis movement
  to `syscons/sysmouse'.
- Removed LEFT_BUTTON, MIDDLE_BUTTON and RIGHT_BUTTON.  Use button bits
  defined in `mouse.h' instead.

/sys/i386/isa/psm.c
- Added a set of functions to detect various mice which have additional
  features (wheel and buttons) unavailable in the standard PS/2 mouse.
- Refined existing ioctl functions and added new ones.  Most important
  of all is MOUSE_SETLEVEL which manipulates the output level of the driver.
  While the output level remains zero, the output from the `psm' driver is
  in the standard PS/2 mouse format (three bytes long).  When the level
  is set to one, the `psm' driver will send data in the extended format.
  At the level two the driver uses the format which is native to the
  connected mouse is used. (Meaning that the output from the device is
  passed to the caller as is, unmodified.)  The `psm'  driver will pass
  such extended data format as is to the caller if the output level is
  two, but emulates the standard format if the output level is zero.
- Added kernel configuration flags to set initial resolution
  (PSM_CONFIG_RESOLUTION) and acceleration (PSM_CONFIG_ACCEL).
- Removed the compile options PSM_ACCEL, PSM_CHECKSYNC and PSM_EMULATION.
  Acceleration ratio is now specified by the kernel configuration flags
  stated above.  Sync check logic is refined and now standard.
  The sync check can be turned off by the new kernel configuration flags
  PSM_CONFIG_NOCHECKSYNC (0x100).  PSM_EMULATION has been of little use.
- Summer clean up :-)  Removed unused code and obsolete comments.

/sys/i386/isa/mse.c
- Created mseioctl() to deal with ioctl functions MOUSE_XXXX.
  Most importantly, the MOUSE_SETLEVEL ioctl will change the
  output format from the 5 byte format to the new, extended format
  so that the caller can take advantage of Z axis movement and additional
  buttons.
- Use constants defined in `mouse.h' rather than magic numbers.

/sys/i386/isa/syscons.c
- Changed scioctl() to reflect the new `console.h' and some of the new
  ioctls defined in `mouse.h'.  Most importantly, the MOUSE_SETLEVEL
  ioctl will change the `sysmouse' output format from the MouseSystems
  5 byte format to the new, extended format so that the caller can
  take advantage of Z axis movement and additional buttons.
- Added support for double/triple click actions of the left button and
  single click action of the right button in the virtual console.  The
  left button double click will select a word under the mouse pointer.
  The triple click will select a line and the single click of the right
  button will extend the selected region to the current position of
  the mouse pointer.  This will make the cut/paste support more compatible
  with xterm.

/sys/i386/isa/kbdio.h
- Added PSM_INTELLI_ID.

0a8ebf33fc Alot of fixes from kazu:
1. All the suggestions earlier made by Bruce: renaming some symbols,
stricter error checking, removing redundant code, etc.

2. The `psm' driver preserves the default counter resolution and
report rate, whatever they are after reset. (Based on reports and
suggestion from Nate and Rob Bolin).

3. The `psm' driver now does not check the so-called sync. bit in the
first byte of the data packet by default, so that the tapping feature
of ALPUS GlidePoint works (based on reports from Louis Mamakos). I
tested the code with ALPUS Desktop GlidePoint (M/N GP101) and found
no problem; tapping worked. It appears ALPUS produces several models
of GlidePoint. I hope the other models are OK too.

The check code can still be activated by defining the PSM_CHECKSYNC
option in the config file. (The bit checking slightly reduces, if not
completely eliminates, weird mouse behavior cased by unsynchronized
mouse data packets. It also helps us to detect if the mouse interrupt
can ever be lost. But, well, if there are devices which cannot be
supported this way...)

4. The `psm' driver does not include the protocol emulation code by
default. The code can still be compiled in if the PSM_EMULATION option
is specified in the config file. Louis Mamakos suggests the emulation
code is putting too much in the kernel, and `moused' works well.
I will think about this later and decide if the entire emulation
code should be removed.

5. And, of course, the fix in `scprobe()' from Bruce to cure the
UserConfig problem. My code in `kbdio.c' is slightly different from
his patch, but has the same effect. There still is a possibility that
`scprobe()' gets confused, if, for whatever reasons, the user holds
down a key for very long time during the boot process. But we cannot
cope with everything, can we?

  duplicates) for compiling LINT.
- include <sys/types.h> if and only it is necessary to make the header
  almost self-sufficient (some ioctl headers still need structs from
  elsewhere).

7d151a09c3 First attempt at FreeBSD & Linux ELF support.
Compile and link a new kernel, that will give native ELF support, and
provide the hooks for other ELF interpreters as well.

To make native ELF binaries use John Polstras elf-kit-1.0.1..
For the time being also use his ld-elf.so.1 and put it in
/usr/libexec.

The Linux emulator has been enhanced to also run ELF binaries, it
is however in its very first incarnation.
Just get some Linux ELF libs (Slackware-3.0) and put them in the
prober place (/compat/linux/...).
I've ben able to run all the Slackware-3.0 binaries I've tried
so far.
(No it won't run quake yet :)

f14a4d4e3f Add support for the old-style Linux termio (not termios) TCGETA etc.
Also, LINUX_POSIX_VDISABLE is \0, FreeBSD's is 0xff. Convert between them.

This enables some more programs to run, including the Livingston Portmaster
utilities (PMtools).

8465726bda Mega-commit for Linux emulator update.. This has been stress tested under
netscape-2.0 for Linux running all the Java stuff.  The scrollbars are now
working, at least on my machine. (whew! :-)

I'm uncomfortable with the size of this commit, but it's too
inter-dependant to easily seperate out.

The main changes:

COMPAT_LINUX is *GONE*.  Most of the code has been moved out of the i386
machine dependent section into the linux emulator itself.  The int 0x80
syscall code was almost identical to the lcall 7,0 code and a minor tweak
allows them to both be used with the same C code.  All kernels can now
just modload the lkm and it'll DTRT without having to rebuild the kernel
first.  Like IBCS2, you can statically compile it in with "options LINUX".

A pile of new syscalls implemented, including getdents(), llseek(),
readv(), writev(), msync(), personality().  The Linux-ELF libraries want
to use some of these.

linux_select() now obeys Linux semantics, ie: returns the time remaining
of the timeout value rather than leaving it the original value.

Quite a few bugs removed, including incorrect arguments being used in
syscalls..  eg:  mixups between passing the sigset as an int, vs passing
it as a pointer and doing a copyin(), missing return values, unhandled
cases, SIOC* ioctls, etc.

The build for the code has changed.  i386/conf/files now knows how
to build linux_genassym and generate linux_assym.h on the fly.

Supporting changes elsewhere in the kernel:

The user-mode signal trampoline has moved from the U area to immediately
below the top of the stack (below PS_STRINGS).  This allows the different
binary emulations to have their own signal trampoline code (which gets rid
of the hardwired syscall 103 (sigreturn on BSD, syslog on Linux)) and so
that the emulator can provide the exact "struct sigcontext *" argument to
the program's signal handlers.

The sigstack's "ss_flags" now uses SS_DISABLE and SS_ONSTACK flags, which
have the same values as the re-used SA_DISABLE and SA_ONSTACK which are
intended for sigaction only.  This enables the support of a SA_RESETHAND
flag to sigaction to implement the gross SYSV and Linux SA_ONESHOT signal
semantics where the signal handler is reset when it's triggered.

makesyscalls.sh no longer appends the struct sysentvec on the end of the
generated init_sysent.c code.  It's a lot saner to have it in a seperate
file rather than trying to update the structure inside the awk script. :-)

At exec time, the dozen bytes or so of signal trampoline code are copied
to the top of the user's stack, rather than obtaining the trampoline code
the old way by getting a clone of the parent's user area.  This allows
Linux and native binaries to freely exec each other without getting
trampolines mixed up.

f14ea10694 First incarnation of our Linux emulator or rather compatibility code.
This first shot only incorporaties so much functionality that DOOM
can run (the X version), signal handling is VERY weak, so is many
other things. But it meets my milestone number one (you guessed it
- running DOOM).

Uses /compat/linux as prefix for loading shared libs, so it won't
conflict with our own libs.

Kernel must be compiled with "options COMPAT_LINUX" for this to work.

Speed improvements (now > 5 times faster than the old syscons).
History now circular buffer, with changeable size.
History scroll by up/down line, up/down page, home and end.
Backtab proberly implemented.
Now space for 96 function keys, 63 allocated standard, default now
  SCO/SYSV compat again as in the old days.
New keyboard definition files ~share/syscons/keymaps/*
Misc fixes for old "hacks" that broke SCO/SYSV compat.

Subject: syscons-1.3
Date: Sat, 29 Jan 94 23:33:50 MET

But here is the (hopefully) final syscons-1.3....

....

I've changed sgetc so it works as the pccons parallel
(it now uses a scgetc internally).


[
There were a couple changes that Bruce Evans sent me that were applied
to this version along with some changes that S'ren didn't incorporate
into the final version.  There will be only minor changes if anything
from this version to his final release.
