 |
|
Hi everyone,
I tried reading posts about the subject but none seemed to fit or help. I have a Core2 Duo system (IBM ThinkCentre 55M) with a 80GB SATA drive. Using hdparm /dev/hda I get:
| Code: | /dev/hda:
multcount = 16 (on)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 16383/255/63, sectors = 156312576, start = 0
|
and using hdparm -i /dev/hda I get:
| Code: | /dev/hda:
Model=ST3808110AS 41N3267 LEN, FwRev=3.AAK, SerialNo=9LR3LSRH
Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs RotSpdTol>.5% }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=4
BuffType=unknown, BuffSize=8192kB, MaxMultSect=16, MultSect=16
CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=156312576
IORDY=on/off, tPIO={min:240,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4
DMA modes: mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5
AdvancedPM=no WriteCache=enabled
Drive conforms to: Unspecified: ATA/ATAPI-1 ATA/ATAPI-2 ATA/ATAPI-3 ATA/ATAPI-4 ATA/ATAPI-5 ATA/ATAPI-6 ATA/ATAPI-7
* signifies the current active mode
|
If I try to run hdparm -d 1 /dev/hda I receive the error:
| Code: | /dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
|
Perhaps my kernel confuguration is not right for my hardware. Running lspci I get:

(If needed I can post my kernel configuration but it may be quite long). What should be the right kernel configuration to enable DMA? |

| hdparm/libata (for SATA drives) currently do not support setting DMA mode on SATA drives. |

but you're not using the SATA drivers in your kernel
when using sata, your HD would be known as /dev/sda instead of /dev/hda (with a recent kernel, that is)

| Hmm.. I must have omti it somehow. Then I suggest to check whether you have compiled in or as a module proper driver for your motherboard/chipset. |

Well, all the things I have in my kernel are compiled in so I don't know why it's not /dev/sda. Here is the configuration of the kernel (I removed the commented lines to make is shorter).

Did all of things here
http://gentoo-wiki.com/HARDWARE_SATA
fail?
I'll check my kernel config later when I get home, since I have ICH-8R chipset; the only difference is that I have an IDE drive connected to SATA controller by IDE slot (maybe it is somehow emulated?). |

| Thanks for the link, but there isn't much over there except for describing a working kernel configuration (which seems to match my configuration). Now that I think of it, it is strange that I get /dev/hda and not /dev/sda. Any insight will be much welcome. |

try to disable the old ATA/IDE options in your kernel
and update your kernel commandline, and your /etc/fstab to point to /dev/sda instead of /dev/hda

After removing the whole of ATA/IDE support I *do* get my drive as /dev/sda. How do I know now if I have dma on? I emerged sdparm but the output is a little cryptic:
| Code: | /dev/sda: ATA ST3808110AS 3.AA
Direct access device specific parameters: WP=0 DPOFUA=0
Read write error recovery [rw] mode page [PS=0]:

ARRE 1 Automatic read reallocation enabled

if you do a hdparm -t /dev/sda and get more than ~10 MB/s you are using DMA, and, if I suspect right, all SATA use DMA "by design", you don't need to enable it.
(when I test IDE HDs without DMA they usually mark between 2 and 8 MB/s)
