- Refined internal interface in keyboard drivers so that:

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

a SIGFPE signal when non-finite or denormalised numbers are used or

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).

isa, pccard etc.

- 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.

etc, are translated into singlebyte codes.

Boy, I'm glad we're not using sup anymore. This update would have been

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?
