| 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. |
