IDE DMA setting not available on 2.4.23 as a module

IDE DMA setting not available on 2.4.23 as a module

[Santiago Garcia Mantinan]

Hi!

Yesterday I started to upgrade my systems to 2.4.23, some of them were
already running pre or rc versions, but when I tried my Pentium MMX wich
boots out of SCSI and on which I like to have IDE driver as a module, I
found that the DMA setting was not working, hdparm was saying:

 setting using_dma to 1 (on)
 HDIO_SET_DMA failed: Operation not permitted

So I changed the driver option to set DMA by default to ON, but nothing
changed, still the same problem, then I tried to compile the IDE driver into
the kernel instead of having it as a module and then the dma support started
to work, either having the driver enable it by default or by setting it with
hdparm.

The motherboard uses a 430TX chipset, thus with a PIIX4 IDE controller.

Is this a bug or is this a known and accepted limitation of having the IDE
driver as a module?

If you want me to test any patch to see if we can fix this, or need any more
info, don't hesitate to contact me.

Regards...

Do you have piix.o module loaded or PIIX support compiled-in?

I had it compiled in, I didn't knew it could be compiled as a module, I have
tried compiling it as a module and DMA works ok, however the module along
with ide-core are not removable as piix says it is being used.

I have compiled the kernel again with ide modular and piix compiled in, just
in case I had not done it that way before and in fact I had done it that way
and I have verified that I had done it like that, DMA doesn't work as PIIX
driver is not used, I don't see any PIIX4 messages or any BM-DMA ones when
doing it this way, that is the problem.

Hope this clarifies things a little bit.

If you need any other info/test, don't hesitate to contact.

Please send dmesg and .config for this case (built-in Intel IDE driver).

thanks,

One thing, I've seen the PIIX_TUNNING or however it was called, option still
around in several places on the kernel tree, one of them was in the help,
while this option is not on the ide driver anymore.
