Unable to use DMA transfer modes

Rounan · 02-12-2004, 04:17 PM

I just upgraded a minimal Debian (re)install to 2.6.2 - I've been through it all before, and this time the upgrade went flawlessly, except:

In trying to enable DMA transfers on my hard disks, I run into:

# hdparm -d1 /dev/hda

/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)

It worked fine with the 2.2.0-compact kernel installed by default.

Some googling revealed that this is usually due to not having included kernel support for your chipset - I'd agree, except according to:

I'm using a very standard intel PCI chipset, for which there's no kernel compile option.
I have the AGP bridge i8xx option compiled as a module - could that be my problem?

Anything I'm missing?

--Rounan

EDIT: Recompiled with AGP support and i8xx chipset in the kernel, not as modules. No effect. Somehow I thought not...

We have the same motherboard chipset(intel brookdale) and this one has a little history which may be relevant. The exact problem you describe was well known in the early 2.4 kernels with the intel brookdale chipset, i.e. could not enable dma although 2.2 kernels were fine. Later 2.4 kernels corrected this problem.
I am currently testing kernel 2.6.2 on mandrake 10-beta2 and dma is enabled. I suspect there may be some kernel support for this chipset which you may have overlooked. IIRC it was a quirk in the intel bios which caused the problem with the then new kernel. I haven't compiled the 2.6 kernel yet but you may want to research this area little more given the above history. It sounds like a kernel problem.

Rounan · 02-13-2004, 07:51 AM

The problem you described happened in the 2.4.19 kernel, was fixable by a patch (2.4.19-ac4) and was fixed in 2.4.20.
... and that's all the fix there is. obviously doesn't help 2.6.2 much.

Would you mind posting relevant sections of your kernel config? If I've missed something, it's not obvious (to me), and I'm not going to be able to find it on my own. I've been over the config with a fine-toothed comb 3 or 4 times in the past couple days.

kilgoretrout · 02-13-2004, 12:30 PM

I'm not sure what the relevant section would be but IIRC the problem was with the pci bus. You would get a resource collision error message at the beginning of the boot process with the effected 2.4 kernels. For what it's worth, here's my pci section of my .config for the mdk2.6.2 kernel:

# Bus options (PCI, PCMCIA, EISA, MCA, ISA)
#
CONFIG_PCI=y
# CONFIG_PCI_GOBIOS is not set
# CONFIG_PCI_GOMMCONFIG is not set
# CONFIG_PCI_GODIRECT is not set
CONFIG_PCI_GOANY=y
CONFIG_PCI_BIOS=y
CONFIG_PCI_DIRECT=y

# CONFIG_MCA is not set
CONFIG_SCx200=m
CONFIG_HOTPLUG=y

Rounan · 02-13-2004, 12:51 PM

Huh.... I don't have ISA cards, so I left out ISA options.
Don't have the legacy proc interface - I just use lspci.

Only differences are:
scx200 - Is this module loaded on your system?
CONFIG_PCI_MMCONFIG - I can't find a kernel option to correspond with this in menuconfig. Do you know what it is? I don't want to just stick it in my config, since we're using different versions.

This is strange...

Rounan · 02-18-2004, 10:22 AM

I still haven't got DMA working.

I upgraded to 2.6.3, hoping there'd be a fix in the new kernel - nada.
I've enabled scx200 in the PCI options, and every other "chipset support" kernel feature as a module - none of them are loading at boot, so I assume I don't need them. Don't know why I would - the IDE controller should be supported by the generic kernel code. It did in the 2.2 Woody kernel.

When I
hdparm -d1 /dev/hda
I still get:

/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)

hdparm -i /dev/hda reveals:

-------------------------------------

however, I am NOT in udma mode, as:

# hdparm /dev/hda

/dev/hda:
multcount = 0 (off)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)

readahead = 256 (on)
geometry = 65535/16/63, sectors = 78125000, start = 0

and hdparm -tT gives 2.6 MB/sec unbuffered transfer. ICK!!!!

Attached are my lspci, dmesg and kernel .config.
Please help if you have any ideas.

Here's just a wild guess; try passing the noapic option at boot. ACPI can screw up a lot of stuff even in the new kernel and you have it loading judging from your dmesg output.

Rounan · 02-19-2004, 08:16 AM

Thanks for the tip, but passing acpi=off didn't change behavior.

Relevant dmesg section now looks like this:

ACPI: Subsystem revision 20040116
ACPI: Interpreter disabled.
ACPI: ACPI tables contain no PCI IRQ routing entries
PCI: Invalid ACPI-PCI IRQ routing table
PCI: Probing PCI hardware
PCI: Probing PCI hardware (bus 00)

PCI: IRQ 0 for device 0000:00:1f.1 doesn't match PIRQ mask - try pci=usepirqmask
PCI: Found IRQ 9 for device 0000:00:1f.1
PCI: Sharing IRQ 9 with 0000:00:1d.2
PCI: Sharing IRQ 9 with 0000:02:02.0

I note it's using the PIIX IRQ router... is this OK for the chipset?
I'm going to try passing acpi=no on a kernel built without any of the "unneeded" chipset supports.

Thanks for your help thus far, kilgoretrout. Much appreciated.

Removed APIC and all extra support modules from kernel.
No change in behavior.
dmesg now looks like:

*grumbles to self about 2 MB/sec hard disk speeds*

Why would this have worked in 2.2 and not now?

Rounan · 02-19-2004, 08:58 AM

Found this buried in syslog:
Feb 19 09:37:16 Debwkstn kernel: PCI: IRQ 0 for device 0000:00:1f.1 doesn't match PIRQ mask - try pci=usepirqmask

So I did.
Now that message doesn't appear in syslog.
But it still didn't fix anything.

i had the same problem. what fixed it for me was enabling CONFIG_BLK_DEV_PIIX=y. now everything works great.

Rounan · 02-20-2004, 09:11 AM

SUCCESS!!!

Thanks so much, kilgoretrout and Altezza2k2.
Solution was to compile PIIx support directly into the kernel, not as module. ACPI is on, and working just dandy.

# hdparm -Tt /dev/hda

/dev/hda:
Timing buffer-cache reads: 1404 MB in 2.00 seconds = 700.36 MB/sec
Timing buffered disk reads: 138 MB in 3.01 seconds = 45.85 MB/sec

HURRAH!

Good one Rouan, there's gonna be a lot of relieved penguin users about. Twas becoming more and more common to see that prob on various boards, especially since the release of 2.6

Rounan · 02-20-2004, 10:25 AM

I don't know if any kernel hackers read these pages, but I'd HIGHLY recommend putting some sort of reference to Intel 84* chipsets in the kernel config help section for the PIIX option. It is FAR from obvious that this driver is needed for DMA on certain chipsets. Is this new as of 2.6?

Even if they used some non-specific term like "intel chipsets", I would have compiled it in right from the start, just to be safe. But since it seemed to apply specifically to a chipset I didn't have....

Just very unclear, is all.
