SubjectRe: IDE tape and SMP

Find an poke this in as an initial test...........

I find that this works on 2/4 chipsets that I have to test with under SMP.
PDC20246 appears to stablize but no DMA transefers are allowed.
HPT343 (unreleased chipset specific) appears to stablize with Fast-ATA
enabled, but no DMA transefers are allowed.

Both Intel and AEC6210 still have troubles, IMHO.

I just grabbed a Colorado 8GB Drive over the weekend for home use.
Something to backup and test with, also.........

Note that using the native software under MSDos 6.22, it flys at about
34MB/minute uncompressed on the Intel-chipset.

static void idetape_setup (ide_drive_t *drive, idetape_tape_t *tape, int minor)
{

drive->ready_stat = 0; /* An ATAPI device ignores DRDY */
- drive->dsc_overlap = 1;
+ drive->dsc_overlap = (drive->id->capability & 0x20) ? 1 : 0;
+
+#if IDETAPE_DEBUG_LOG
+ printk (KERN_INFO "ATAPI overlap : %sabled.\n",
+ drive->dsc_overlap ? "en" : "dis");
+#endif /* IDETAPE_DEBUG_LOG */
