.Nm ispcvt

|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm ispcvt
|
|
utility allows the user to check whether the current video driver compiled
|
|
into the kernel is a pcvt driver. The major and minor release numbers of
|
|
the driver are also checked.
|
|
Furthermore
|
|
.Nm ispcvt
|
|
is also able to print out the values of all the
|
|
.Dq Ar PCVT_XXXXXX
|
|
compile time options, the driver in the current running kernel was
|
|
compiled with.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Fl d
|
|
Specifies a device for which the check is done.
|
|
.It Fl v
|
|
Specifies being verbose. On success the name and revision is reported, on
|
|
failure which comparison failed.
|
|
.It Fl c
|
|
This options prints out the values of all
|
|
.Dq Ar PCVT_XXXXXX
|
|
#defines which were given to the compiler at the time the currently running
|
|
kernel was compiled. Specifying
|
|
.Fl v
|
|
with the
|
|
.Fl c
|
|
option gives a verbose listing of the compile-time options.
|
|
