 Posted: Sat Nov 06, 2004 4:57 pm Post subject: Kein DMA: hdparm -Tt /dev/hda => 1,7 MB/s |
 |
|
Hallo,
Ich hab heute mal hdparm emerged und damit meine Platte getestet. Es kommen dabei Werte zwischen 1,7 bis 5 MB/s heraus.
Als erstes ist DMA nicht aktiviert... doch dass kann ich auch nicht ändern:
| Code: | bash-2.05b# hdparm -d 1 /dev/hda
/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off) |
Ich verwende die gentoo-dev-sources, "linux-2.6.9-gentoo-r1"
Ich habe einen AMD Chipsatz, (AMD 761, ich glaub das war die genaue Bezeichnung) und habe desshalb zu erst die Unterstützung für diesen Chipsatz unter "Device Drivers ---> ATA/ATAPI/MFM/RLL support ---> AMD and nVidia IDE support" aktiviert.
"Generic PCI bus-master DMA support" hatte ich schon aktiviert. "Intel PIIXn chipsets support " war auch schon standardmäßig aktiviert. Auch "Use PCI DMA by default when available" ist aktiviert.
Und jetzt weiß ich nicht mehr weiter.
Kann mir jemand Helfen  ? |

what did you do to make timing like you wrote?
i've got same hda like you, but my timings are (kernel-2.6.7):
| Code: | # hdparm -Tt /dev/hda
/dev/hda:
Timing cached reads: 772 MB in 2.00 seconds = 385.87 MB/sec
Timing buffered disk reads: 50 MB in 3.07 seconds = 16.31 MB/sec |
if I remember good, on kernel 2.4.x my timings were just like yours now, so I wonder what you did to make your hd run properly..
ps. please in english |

my settings are:
| Code: | /dev/hda:
multcount = 16 (on)
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 65535/16/63, sectors = 61492838400, start = 0 |
I don't really know much about hdparm... these where the default settings with my installation. I hope this will help you.
My kernel is "linux-2.6.9-gentoo-r1" |
