- This is a first attempt to create an `improved' driver for the Mitsumi drives.
- It is able to "live together" with mcd.c, if you have at least two Mitsumi
- drives: each driver can use its own drive.
- To allow this "coexistence" as long as mcdx.c is not a superset of mcd.c,
- this driver has to use its own device files. We use MAJOR 20 for it. So,
- you have to do
- # mknod /dev/mcdx0 b 20 0
- # mknod /dev/mcdx1 b 20 1
- and so on, one entry for each drive to support, once.
- If you are using the driver as a module, you can specify your ports and IRQs
- like
- # insmod mcdx.o mcdx=0x300,11,0x304,5
- and so on ("address,IRQ" pairs).
- This will override the configuration in mcdx.h.
- This driver:
- o handles XA and (hopefully) multi session CDs as well as
- ordinary CDs;
- o supports up to 5 drives (of course, you'll need free
- IRQs, i/o ports and slots);
- o uses much less kernel memory than the standard mcd driver
- (no extra driver internal buffers!).
- o plays audio (like the `old' driver, I hope)
- This version doesn't support yet:
- o shared IRQs (but it seems to be possible - I've successfully
- connected two drives to the same irq. So it's `only' a
- problem of the driver.)
- This driver never will:
- o Read digital audio (i.e. copy directly), due to missing
- hardware features.
