.Nd Mitsumi CD-ROM driver
|
|
.Sh SYNOPSIS
|
|
.Cd "device mcd 1"
|
|
.Pp
|
|
In
|
|
.Pa /boot/device.hints :
|
|
.Cd hint.mcd.0.at="isa"
|
|
.Cd hint.mcd.0.port="0x300"
|
|
.Cd hint.mcd.0.irq="10"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides a data and audio interface to the Mitsumi-brand CD-ROM
|
|
player.
|
|
The CD-ROM player must be interfaced to the ISA bus through
|
|
one of the Mitsumi proprietary controller boards.
|
|
The controller
|
|
boards supported are the LU002S, LU005S, the FX001 and the quite
|
|
common FX001D.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver responds to disk-specific
|
|
.Fn ioctl
|
|
commands, namely the
|
|
.Dv DIOCGDINFO ,
|
|
.Dv DIOCGPART ,
|
|
.Dv DIOCWDINFO ,
|
|
and
|
|
.Dv DIOCSDINFO ,
|
|
commands.
|
|
Other disk-specific
|
|
.Fn ioctl
|
|
commands will return an error.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver also responds to special CD-ROM
|
|
.Fn ioctl
|
|
commands.
|
|
These commands
|
|
control the CD-ROM player's audio features.
|
|
The commands are:
|
|
.Pp
|
|
.Bl -tag -width CDIOCREADSUBCHANNEL -compact -offset indent
|
|
.It CDIOCREADSUBCHANNEL
|
|
get sub-channel information on current status of disc playing
|
|
.It CDIOCREADTOCHEADER
|
|
get table of contents header
|
|
.It CDIOCREADTOCENTRYS
|
|
gets all of the table of contents
|
|
.It CDIOCPLAYTRACKS
|
|
begins audio playing at location specified
|
|
.It CDIOCPLAYBLOCKS
|
|
fails with error
|
|
.Er EINVAL
|
|
.It CDIOCPLAYMSF
|
|
begins audio playing at location specified
|
|
.It CDIOCRESUME
|
|
resumes playing a previously paused disc
|
|
.It CDIOCPAUSE
|
|
pauses a playing disc
|
|
.It CDIOCSTART
|
|
begins playing a disc
|
|
.It CDIOCSTOP
|
|
stops a previously playing disc
|
|
.It CDIOCEJECT
|
|
opens the disc tray (there is no support for a corresponding un-eject
|
|
command).
|
|
.It CDIOCRESET
|
|
stops any play and resets the Mitsumi controller board
|
|
.It CDIOCSETDEBUG
|
|
cause the kernel to print debug messages to the console about the
|
|
.Nm
|
|
driver
|
|
.It CDIOCCLRDEBUG
|
|
cause the kernel to quit printing debug messages about the
|
|
.Nm
|
|
driver
|
|
.El
|
|
.Pp
|
|
The
|
|
.Fn ioctl
|
|
commands defined above are the only ones that the
|
|
.Nm
|
|
driver supports.
|
|
There are other CD-ROM related
|
|
.Fn ioctl
|
|
commands (such as
|
|
.Dv CDIOCSETVOL
|
|
and
|
|
.Dv CDIOCSETSTERIO )
|
|
which are available
|
|
and may be supported by future versions of the driver.
|
|
.Sh FILES
|
|
.Bl -tag -width /dev/(r)mcd0a -compact
|
|
.It Pa /dev/(r)mcd0a
|
|
accesses
|
|
.Bx
|
|
partition on the disc.
|
|
Normally, there is only
|
|
one file system on a CD-ROM disc.
|
|
.It Pa /dev/(r)mcd0c
|
|
accesses raw device.
|
|
.El
|
|
.Sh NOTES
|
|
The character-mode devices for the
|
|
.Nm
|
|
driver should only be used for accessing the audio features of the
|
|
CD-ROM player as the performance on data is abysmal.
|
|
.Pp
|
|
The current version of the driver uses neither the DMA or IRQ
|
|
features of the interface board, although it has an interrupt handler
|
|
for any IRQ requests that are generated.
|
|
Until the DMA features are
|
|
supported, the only interrupts that the board generates are those that
|
|
aren't supported by the driver anyway.
