I tried this out just as soon as I saw the announcement! Your driver is
really coming along well. I have three basic problems with it:
1. A hard reset is necessary to get the CD-ROM drive to work with acd.
wdc0: unit 1 (atapi): <NEC CD-ROM DRIVE:285/3.04>, removable,
dma, iordy
wcd0: drive speed 2067KB/sec, 128KB cache
wcd0: supported read types: CD-R, CD-DA
wcd0: Audio: play, 16 volume levels
wcd0: Mechanism: ejectable tray
wcd0: Medium: no/blank disc inside, unlocked
2. My LS-120 still has no reliability with the driver, as reads are
corrupted extremely often.
wdc1: unit 0 (atapi): <LS-120 COSM 02 UHD Floppy/0271C09T>,
removable, iordy
wfd0: medium type unknown (no disk)
3. DMA is ineffective with file-system use. I can read from the raw
device rad0 at 4.5MB/s with a 1mb block size, but when I use iozone performance
is around 2.5MB/s. Mounting wd shouldn't affect that, should it? I used the
same device special files to mount as before, with ATA_STATIC being used,
and noticed this. Better yet, I'll try this with a corrected fstab then
report back.
