of the various ad-hoc schemes.
2) When bringing in UPAGES, the pmap code needs to do another vm_page_lookup.
3) When appropriate, set the PG_A or PG_M bits a-priori to both avoid some
processor errata, and to minimize redundant processor updating of page
tables.
4) Modify pmap_protect so that it can only remove permissions (as it
originally supported.) The additional capability is not needed.
5) Streamline read-only to read-write page mappings.
6) For pmap_copy_page, don't enable write mapping for source page.
7) Correct and clean-up pmap_incore.
8) Cluster initial kern_exec pagin.
9) Removal of some minor lint from kern_malloc.
10) Correct some ioopt code.
11) Remove some dead code from the MI swapout routine.
12) Correct vm_object_deallocate (to remove backing_object ref.)
13) Fix dead object handling, that had problems under heavy memory load.
14) Add minor vm_page_lookup improvements.
15) Some pages are not in objects, and make sure that the vm_page.c can
properly support such pages.
16) Add some more page deficit handling.
17) Some minor code readability improvements.
so that it is possible for kdump and truss to include them both. Use
#defines from pcvt_ioctl.h in conflicting cases, since pcvt_ioctl.h
gives a hint about the bogus third arg to _IO(). Ifdef the common
typedefs. Export `struct key_t' from pcvt_ioctl.h so pcvt_ioctl.h is
bug for bug compatible with console.h (now both are broken in C++
mode).
1. Takeshi Ohashi <ohashi@atohasi.mickey.ai.kyutech.ac.jp> submitted
code to support bktr_read . /usr/src/share/examples/rgb24.c now works 8)
2. Flemming Jacobsen <fj@schizo.dk.tfs.com> submitted code to support
radio available with in some bt848 based cards;additionally, wrote
code to correctly recognized his bt848 card.
3. Roger Hardiman <roger@cs.strath.ac.uk> submitted various fixes to smooth
out the microcode and made all modes consistent.
4. Added supported for yuv12 so we know can capture raw streams and feed it
to mpeg_encoder . The upshot is that we can now mpeg encode more and save
nearly 100 percent of the disk requirements previously for programs such
as fxtv first save the raw video image to disk then converted to a
format suitable for mpeg_encode.
Move sigjmp_buf and jmp_buf structure definitions to machine/setjmp.h
so that i386 can continue to use int as the basic register type and
alpha can use long. Bruce was concerned about possible differing
alignment. I've left the definition of _JBLEN in machine/setjmp.h
even though Bruce's example used the number directly. I don't know if
any other code relies on _JBLEN, so I left it to avoid potential
breakage.
and int32_t -- this adds their unsigned counterparts uint8_t, uint16_t,
and uint32_t. Bruce has noted that C9x also defines these types (in a
different file), so this may have to be revisited with some ifdefs at a
later date.

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).
- A nonprofiling version of s_lock (called s_lock_np) is used
by mcount.
- When profiling is active, more registers are clobbered in
seemingly simple assembly routines. This means that some
callers needed to save/restore extra registers.
- The stack pointer must have space for a 'fake' return address
in idle, to avoid stack underflow.
noticed some major enhancements available for UP situations. The number
of UP TLB flushes is decreased much more than significantly with these
changes. Since a TLB flush appears to cost minimally approx 80 cycles,
this is a "nice" enhancement, equiv to eliminating between 40 and 160
instructions per TLB flush.
Changes include making sure that kernel threads all use the same PTD,
and eliminate unneeded PTD switches at context switch time.

- 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.
battery time. For backward compatibility with old binaries, I
assigned a new ioctl number for this call, and retained the old
one as APMIO_GETINFO_OLD. I also added eight words of padding and
a version field, so that future enhancements won't require jumping
through this hoop again.
