 Posted: Fri Nov 03, 2006 12:29 pm Post subject: DMA Aktivierung - geht nicht |
 |
|
Hallo,
ich bekomme die DMA Aktivierung meines DVD-Laufwerkes einfach nicht an!!!
Hier zunächst ein paar Informationen:
| Quote: | hdc: MATSHITADVD-RAM UJ-841S, ATAPI CD/DVD-ROM drive
hdc: ATAPI 24X DVD-ROM DVD-R-RAM CD-R/RW drive, 2048kB Cache |
| Quote: | | 00:1f.2 IDE interface: Intel Corporation 82801FBM (ICH6M) SATA Controller (rev 03) |
Im Kernel habe ich bezüglich IDE und DMA folgendes aktiviert:
| Code: | | nano -w /usr/src/linux/.config |
| Quote: | [...]

hdparm spuckt folgendes aus:
| Quote: | /dev/hdc:
Model=MATSHITADVD-RAM UJ-841S, FwRev=1.00, SerialNo=
Config={ Fixed Removeable DTR<=5Mbs DTR>10Mbs nonMagnetic }
RawCHS=0/0/0, TrkSize=0, SectSize=0, ECCbytes=0
BuffType=unknown, BuffSize=0kB, MaxMultSect=0
(maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0
IORDY=on/off, tPIO={min:240,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4
DMA modes: sdma0 sdma1 sdma2 mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 *udma2
AdvancedPM=no
Drive conforms to: Unspecified: ATA/ATAPI-3 ATA/ATAPI-4 ATA/ATAPI-5 ATA/ATAPI-6
* signifies the current active mode |
Wenn ich nun versuich DMA zu aktivieren erhalte ich die folgende Meldung:
| Code: | | hdparm -d1 /dev/hdc |
| Quote: | /dev/hdc:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off) |
Naja vieleicht hat ja jemand von euch eine Idee.
Jedenfalls schonmal besten Dank für alle Antworten

Namd,
SATA hat doch gar kein flag dafür oder?
Jedenfalls sagt bei mir ein hdparm /dev/sda folgendes:
| Code: | /dev/sda:
IO_support = 0 (default 16-bit)
readonly = 0 (off)
readahead = 256 (on)
geometry = 19457/255/63, sectors = 312581808, start = 0

das ist etwas was ich nicht so ganz verstehe.
Da steht SATA Controler. Läuft aber dennoch als ATAPI unter /dev/hdc.
Und hdparm spuckt folgendes aus
| Quote: | IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
HDIO_GETGEO failed: Inappropriate ioctl for device |
Also doch DMA!!!
Aber wie geht es an?

Bist du sicher, dass das Laufwerk SATA ist? Sieht sehr sehr stark nach IDE aus 
Dann könnte der Grund sein, dass die der Treiber für den IDE-Controller fehlt.
Für den SATA-Controller solltest du CONFIG_SCSI_ATA_PIIX anstelle von CONFIG_BLK_DEV_PIIX benutzen.
