Sorry for the confusion!  My driver sets up our device for a DMA (address
and length) and then gives the command
for the DMA to start.  Once the device has completed the transfer, it
asserts its interrupt, the driver clears it and proceeds to set up the next
data transfer.  It runs for awhile, but then eventually hangs (I don't get
interrupts and neither does anything else - keyboard, ethernet, etc).  I
simply added debug to do_IRQ in the kernel to track the desired IRQ.  I also
added a routine to read the 8259 Interrupt Controller Registers when
requested.  Then I had a user app and driver which simply called this new
new routine in the kernel to return the status of the 8259 and the debug
counters I added to do_IRQ.  Once the system failed, this debug information
showed that not only was Linux NOT receiving the interrupt, but neither was
the 8259.  When I changed my driver to poll the device for DMA completion
instead of rely on an interrupt, it still locked up.

>memtest is usually suggested, when it is not sure that

I tried it for kicks.  It ran for a couple of hours and produced NO errors.

. . . Meanwhile, I made another discovery on the internet that indicates
that DMA is not supported with an ICH4 controller (which is what this system
has) until Linux version 2.5.12 (we're using 2.4.20-8).  See:
http://64.143.3.64/downloads/drivers/845/perform/linux/udma.htm.  I posted a
question concerning this to linux-kernel.  See thread:  DMA not supported
with Intel ICH4 I/O controller?  Unfortunately, I have not received any
response that supports or refutes this.  Any thoughts?

Thanks,
Kathy

I understand this is your device doing DMA (= access) - i.e. your
PCI card is transfering to/from system RAM? This has nothing to do with
any UDMA and it works with any Linux kernel and system hardware which
support PCI.

Are you using some standard PCI bridge by chance? Are you sure it isn't
a hardware (design or manufacturing) problem with the device (bridge)?
How do you check interrupt request state?

We are using the ASUS P4PE MoBo - Uses Intel 845PE chipset.  The message
file indicates:

Transparant bridge - Intel Corp. 82801BA/CA/DB PCI bridge

>How do you check interrupt request state?
I assume you are referring to the kernel debug stuff that I added?  The
routine I added simply read the Interrupt Mask Register (IMR), Interrupt
Request Register (IRR) and the Interrupt Service Register (ISR).  The IMR
shows that our IRQ is not masked off.  The IRR shows that there is currently
no interrupt pending for our IRQ.  The ISR shows that we are not currently
servicing our IRQ.

Kathy

Actually I was thinking about an IC on your card, something like
PLX PCI9080 chip - i.e. the chip connected to the PCI bus and doing
the DMA transfers (many specialized controllers have built-in PCI
bridge, though).

Could you please state if you are using bus mastering PCI DMA, or
if it is IDE DMA (an IDE hard disk etc) thing?

We have an Altera EPLD on our device which is PCI 2.2 compliant.

bus master DMA.

This same board works in an Sun Ultra 5 under Solaris and also works on
slower PCs using Linux Red Hat 8.0 and 9.0.  (i.e., all my stress testing
was done on a MoBo with an Intel 815E Chipset using an ICH2 I/O Controller
Hub.  It worked beautifully there!)

We are attached to some industrial equipment.  Yes, DMA busmaster.  Yes, the
device asserts it's interrupt.  At some point things get totally hosed and
that interrupt never gets through.  We then have to reset the machine . . .

Thanks.  A couple of others have responded similarly.

Nope, we don't use the IDE interface.

We are using the ASUS P4PE MoBo (chipsets:  Intel 82845PE MCH and Intel

Below you'll find additional info on the system.  Please let me know what

Looks like malfunction of your card or driver. Is it a new design or
is it already working with, say, Windows or something?

Does the above list include your card? Which one is it? Could you show
lspci -vv output for that device?

Is is your driver?

Have you tried running the box (with your card) without any unnecessary
devices (plugged/loaded)?

That would appear to be the case. But as I said, it appears to be a nasty
side affect from something that has gone wrong during a DMA transfer.  BTW,

Why?  The device is _still_ a DMA device.  In this particular test I told it
to initiate the DMA, but I did not enable it's ability to interrupt me when
it was finished with the DMA.  I poll to watch for it's completion.

I haven't ruled that out.

. . . Meanwhile, I made another discovery on the internet that indicates
that DMA is not supported with an ICH4 controller (which is what this system
has) until Linux version 2.5.12 (we're using 2.4.20-8).  See:
http://64.143.3.64/downloads/drivers/845/perform/linux/udma.htm.  I posted a
question concerning this to linux-kernel.  See thread:  DMA not supported
with Intel ICH4 I/O controller?  Unfortunately, I have not received any
response that supports or refutes this.  Any thoughts?

Thanks,
Kathy

Problems related to DMA or DDR memory on Intel 845 chipset?

[Kathy Frazier]

Hello all,

I posted a message a few weeks back concerning a problem I was having with
our device not receiving interrupts.  Our system will run for awhile and
then "hang".  I had discovered that upon this failure, the logic analyzer
shows that our device is asserting the interrupt.  However, I also found (by
adding my own debug to the kernel) that the 8259 Programmable Interrupt
Controller never received the interrupt (it's bit was not set in the
Interrupt Request Register, nor did I ever reach my ISR to clear the
interrupt on the device).  At this point of failure, no other IRQs are
getting through, so the system appears to be completely hard hung even
though various software components are still running.  We are operating in a
system with an ASUS P4PE motherboard (uses the Intel 845PE chipset and
employs the DDR memory technology) running Linux 2.4.20-8.   Further testing
has shown that "not receiving an interrupt" is just a nasty side affect from
something that has gone wrong during a DMA transfer by our device.  This was
discovered when I changed the driver to poll for a DMA completion rather
than have it interrupt me.  Our system still hung.  We are have tried
tweaking various BIOS settings (set memory freq, DDR reference voltage, PCI
latency amoung others) but have not had any luck.  We also tried some slower
DDR memory without luck.  Another thing worth mentioning:  When I built a
debug version of the kernel, I turned on several of the kernel hacking
features and added some of my own debug in the do_IRQ routine.  I had a user
application query a new home grown debug routine in the kernel (via another
driver) to see what the status was with respect to the interrupt I was
watching and the state of the 8259.  All of this changed the timing enough
that the system would complete a 3 hour test instead of the usual case in
which it dies in minutes under a non-debug kernel.  Also, our device and
software work fine in a Pentium III system (using Intel 815E chipset with
133/100 MHz SDRAM) with the same (non-debug) version of Linux.  So it seems
that this problem is sensitive to timing/speed.

In posting this, I'm hoping that someone may be able to lend some advice on
the situation.  I have seen some past threads on this mailing list dealing
with issues of IDE DMA problems with Intel 845 chipset in version 2.4.19 of
the kernel.  There were evidently some patches to this version (-ac1
through -ac3) which address these problems.  Did these changes make it to
2.4.20?  Or could the problem be due to the faster DDR memory?  I have seen
some references to the memtest86 tool, but I'm not sure if that would shed
any light on this problem.  I've downloaded, but have not tried it yet.  Any
advice is welcome.  Please let me know if I can provide you with any
additional information.

Thanks in advance for your help.
