No DMA with HTP370 IDE controller

No DMA with HTP370 IDE controller

[Michael Bueker]

Hello,

[please CC me upon replying - thank you]

I have a Highpoint 370 PCI IDE controller, and both my 2.6.18.2 and 
Knoppix 5's 2.6.17 display the following messages:

(hdf is naked, there's no error in partition detection)

The same messages appear when manually trying to enable DMA with hdparm. 
The hdparm reading of hde is:

> /dev/hde:
>  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     = 65535/16/63, sectors = 78165360, start = 0

hda, which is on the mainboard controller and works as hde used to as 
well, reads:

> /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 = 117231408, start = 0

In the controller's setup utility, I can choose access modes. If i 
switch it from UDMA5 to PIO0, the only difference during boot is:

> ide2: BM-DMA at 0xa000-0xa007, BIOS settings: hde:pio, hdf:pio

instead of

> ide2: BM-DMA at 0xa000-0xa007, BIOS settings: hde:DMA, hdf:DMA

Please help me getting DMA to work with this controller.

Thanks in advance,

Please try 2.6.20-rc4 and 2.6.20-rc3-mm1.

Both contain many fixes to IDE hpt driver (but -mm some more than vanilla).

I applied all of these patches, but the errors remains just the same. I 
actually did it twice to be sure, but to no avail.

    Then it's probably the same issue as here:

http://bugzilla.kernel.org/show_bug.cgi?id=7703

    What's really strange is that my HPT370 is working fine.  However, the 
chip marking says it's HPT370A despite the revision ID is 3 (which should 
correspond to HPT370)...

Unfortunately, I'm unable to compile a 2.4.18 kernel (my gcc is probably
too new) for testing.

But anyways - do you think there's hope for fixing this? If I can
provide you with any more helpful information, please tell me.

My controller is:

Does the libata driver work?

    Hope dies last. :-)
    Unfortunately, I don't have enough time to work on this, and the fact that
it's not locally reproducible also doesn't help.  I'll try to come up with
something to test but not very soon...

    Exactly what I have here but the chip marking is HPT370A. A bit puzzling...

Nope. There's no verbose error messages, but the kernel dies about where 
the controller is addressed.
