Hi all,
I'm trying to use UDMA66 in my computer but haven't suceeded
until now.
Configuration:
Epox EP-MVP3G2 with VIA MVP3 AGPset, K6-3D 450Mhz
hda: Seagate ST313021A, ATA66 capable. hdparm -iI /dev/hda says:
/dev/hda:
Model=ST313021A, FwRev=3.03, SerialNo=3CT0A95K
Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs RotSpdTol>.5% }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=4
BuffType=0(?), BuffSize=512kB, MaxMultSect=32, MultSect=off
DblWordIO=no, OldPIO=2, DMA=yes, OldDMA=2
CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=25434228
tDMA={min:120,rec:120}, DMA modes: mword0 mword1 mword2
IORDY=on/off, tPIO={min:240,w/IORDY:120}, PIO modes: mode3 mode4
UDMA modes: mode0 mode1 mode2 mode3 *mode4
Model=TS130312 A, FwRev=.330, SerialNo=C30T9AK5
Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs RotSpdTol>.5% }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=4
BuffType=0(?), BuffSize=512kB, MaxMultSect=32, MultSect=?32?
DblWordIO=no, OldPIO=2, DMA=yes, OldDMA=2
CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=25434228
tDMA={min:120,rec:120}, DMA modes: mword0 mword1 mword2
IORDY=on/off, tPIO={min:240,w/IORDY:120}, PIO modes: mode3 mode4
UDMA modes: mode0 mode1 mode2 mode3 *mode4
I use Debian GNU/Linux 2.2, kernel 2.2.17-ide with Andre Hedrick's IDE
patches applied.
kernel at boot time says:
Uniform Multi-Platform E-IDE driver Revision: 6.30
ide: Assuming 33MHz system bus speed for PIO modes; override with
idebus=xx
VP_IDE: IDE controller on PCI bus 00 dev 39
VP_IDE: not 100% native mode: will probe irqs later
VT 82C597 Apollo VP3
Chipset Core ATA-33
Split FIFO Configuration: 8 Primary buffers, threshold = 1/2
8 Second. buffers, threshold = 1/2
ide0: BM-DMA at 0xe000-0xe007, BIOS settings: hda:DMA, hdb:DMA
ide0: VIA Bus-Master (U)DMA Timing Config Success
ide1: BM-DMA at 0xe008-0xe00f, BIOS settings: hdc:DMA, hdd:DMA
ide1: VIA Bus-Master (U)DMA Timing Config Success
hda: ST313021A, ATA DISK drive
hdb: ST1144AT, ATA DISK drive
hdc: CD-ROM 48X/AKU, ATAPI CDROM drive
hdd: IOMEGA ZIP 100 ATAPI Floppy, ATAPI FLOPPY drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
hda: ST313021A, 12419MB w/512kB Cache, CHS=1583/255/63
hdb: ST1144AT, 124MB w/16kB Cache, CHS=1001/15/17
hdc: ATAPI 48X CD-ROM drive, 128kB Cache
In this preconfigured kernel CONFIG_IDEDMA_AUTO is disabled so
DMA is disabled at boot time.
I've a secondary HD which is an old IDE drive. hdparm -iI /dev/hdb says:
/dev/hdb:
Model=ST1144AT, FwRev=rev 5.50, SerialNo=00KA8945150000000000
Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>5Mbs RotSpdTol>.5% }
RawCHS=1001/15/17, TrkSize=9792, SectSize=576, ECCbytes=7
BuffType=3(DualPortCache), BuffSize=16kB, MaxMultSect=0
DblWordIO=yes, OldPIO=0, DMA=yes, OldDMA=0
(maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0
Model=TS1144TA, FwRev=er v.505, SerialNo=00AK9854510000000000
Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>5Mbs RotSpdTol>.5% }
RawCHS=1001/15/17, TrkSize=9792, SectSize=576, ECCbytes=7
BuffType=3(DualPortCache), BuffSize=16kB, MaxMultSect=0
DblWordIO=yes, OldPIO=0, DMA=yes, OldDMA=0
(maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0
Questions:
1.- If I execute hdparm -d1 -X34 (DMA mode 2), the kernel starts
panicking
and halts. Why? (after that, I haven't even tried -X68 (UDMA66))
2.- How come the kernel recognizes 'VT 82C597 Apollo VP3' instead of the
more
logical 'VT 82C598 Apollo MVP3'?
3.- I guess that since beginning with kernel 2.2, CONFIG_IDEDMA_AUTO is
disabled by default, there must be some faulty HD/IDE controller combos
out there when working in U/DMA mode. Whose fault is it? ST313021A works
perfectly in UDMA33 with ALI15X3 chipset.
4.- Would you recommend to put the old IDE drive as slave? does it slow
down the access to the ATA66 one?
Please, CC to my e-adress.
cheers

Hi!
No chance getting this to work on 2.2 now, try 2.4.0, it should work.
I hope to fix 2.2 later ...
