hdparm on FC7

[Jovan Spasojevic]

Hello,

sience FC7 i am not more able to set the (E)IDE 32-bit I/O support
and multiple sector I/O sience fedora 7
on Fedora 5 and 6 there was no problem i have write the comandos in 
rc.local (/sbin/hdparm -c3 -m16 /dev/hda) (now it /dev/sda) and works.
now on fc7 don't wokrs anymore all opts are marked as "off" only runs in 
UDMA 5 Mode. i have this options set because it have a better 
input/output Support/performance on my IDE/ATA100 HDD.

Why hdparm not works anymore. I think it is the new SATA Protocoll.

The Error that appears is:

[root@localhost jovan]# /sbin/hdparm -c3 -m16 /dev/sda

/dev/sda:
  setting 32-bit IO_support flag to 3
  HDIO_SET_32BIT failed: Invalid argument
  setting multcount to 16
  HDIO_SET_MULTCOUNT failed: Inappropriate ioctl for device
  HDIO_GET_MULTCOUNT failed: Inappropriate ioctl for device
  IO_support   =  0 (default 16-bit)


/dev/sdb:
  setting 32-bit IO_support flag to 3

  HDIO_GET_MULTCOUNT failed: Inappropriate ioctl for device
  IO_support   =  0 (default 16-bit)
[root@localhost jovan]#


This is the current output from hdparm:

/dev/sda:
  IO_support   =  0 (default 16-bit)

  * signifies the current active mode

But there is a error i have a Intel 775 Asrock Motherboard with ATA100 
and my Hardware support UDMA5 not UDMA6 (see above)

I noticed the same behavior on FC7... and a search of Google and 
fedoraforum.org didn't provide any enlightenment.

Does anyone know the explanation?

F7 uses libata for IDE too.
libata does not support this commands.

[Jovan Spasojevic]

So have anybody a workaround? Sdparm or what?

In DMA modes the 32bit I/O feature and multi-sector mode are not used. For
the moment libata also only supports 32bit PIO on some controllers and for those
it si handled automatically. Over time it may well gain 32bit support for more,
but again the goal is it will be entirely automatically done if so.

Coincidentally, I just saw an announcement for something called sdparm. 
No idea if it's relevant or not.

Ahhh, that makes sense. Thanks.
