.Sh BUGS
|
||||
Data loss is possible on busy systems with baud rates greater than 300.
|
||||
The
|
||||
.Nm com
|
||||
driver is slow, buggy, and not properly tested.
|
||||
.Pp
|
||||
The name of this driver and the constants which define the locations
|

of the various seiral ports are holdovers from

|
||||
As usual, you get what you pay for; cheap NS16550 clones
|
||||
generally don't work.

the parallel port controller will not cause an interrupt, and

therefore must poll the controller.

|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm npx
|
||||
driver enables the use of the system's Numeric Processing Extension
|
||||
coprocessor,
|
||||
if one is present. Numeric processing extensions are present in
|
||||
systems with
|
||||
.Nm 486DX
|
||||
CPUs and in systems with
|
||||
.Nm 387
|
||||
or
|
||||
.Nm 487SX
|
||||
coprocessors. The
|
||||
.Nm npx
|
||||
driver is required for proper system functioning regardless
|
||||
of whether or not a NPX is present.
|
||||
.Pp
|
||||
If there is no NPX present in the system, the "MATH_EMULATE"
|
||||
option must be defined in the kernel configuration file.
|
||||
It will provide support for the instructions normally executed
|
||||
by the NPX. If there is no NPX in the system and the kernel
|
||||
is not built with math emulation, the system will not boot.
|
||||
.Sh CAVEATS
|
||||
The emulator is much slower than the NPX coprocessor.
|
||||
This will result in poor floating-point math performance
|
||||
if the emulator must be used.
|
||||
.Sh BUGS
|
||||
There are lots of them, especially on cheap motherboards. In particular,
|
||||
some motherboards do not have the interrupt lines from the NPX to
|
||||
the CPU wired properly. If this is the case, the emulator must be used
|
||||
if consistent system operation is desired.
|
||||
.Pp
|
||||
Emulation of the transcendental functions instructions is incorrect.
|
||||
Emulation of other instructions is suspect.
