Fixing the broken CC: list, it's "netdev" not "linux-netdev".

x86-64, intel P965...
Can you provide "dmesg" output, please?
I wonder what additional side effect did the patch cause. Streaming
allocs on such x86 should already be coherent, no?
Perhaps you have more than 2 GB RAM (or so) and swiotlb has to provide
buffering? I think of something like:
- the driver does "sync for CPU" and examines status
- the descriptor is tested to be still empty
- meanwhile e100 chip changes the status in the descriptor
- the driver does "sync for device" (it's what the patch added)
- at this point swiotlb doesn't know the descriptor is clean and writes
it out, thus dropping the change done by the e100 chip.
Does the above seem plausible? I admit I'm not swiotlb expert, it's
a pure guess that it simply and blindly moves data in and out.
If that's the case, I don't really know how could it work without the
patch in question. Perhaps the timings were just right?
What can we do with it? Rewriting to use consistent allocs, of course.
Temporarily adding #ifdef CONFIG_ARM around the
pci_dma_sync_single_for_device()? Not sure if other archs were affected.
The root problem is that the driver shouldn't use streaming allocations
for its descriptors (they are written from both sides simultaneously).
Only skb->data can be streaming.

skb->data is where e100 puts it's descriptors. :-)
But you know that.

Right. I will try to change that soon.

Hi Krzystof,
dmesg is attached. This box does have >2GB Ram (6GB total). The dmesg will show e100 init'd 3 times since the first is the stock modprobe, 2nd was forced with use_io and the 3rd modprobe was after reverting the patch.

You most probably can't test without swiotlb (RAM has to be limited to
2 GB or so), can you? That would (dis)prove my theory. Alternatively (or
better), a test on IOMMU-equipped system would do.
Since swiotlb is x86-only thing (though other 64-bit archs may have
something similar), I think the correct work around is to enable the
"for_device" handoff on !X86.
Something like maybe:

I'm not willing to apply something like this.
swiotlb emulates what hardware does, so if it can go wrong with
swiotlb it can go wrong with hardware to.
Figure out what the exact bug is.

I think I already have.
The exact bug is using streaming allocations for the descriptor.
It can't work consistently on all platforms, period. Streaming
allocation can only have one owner (either CPU or device) at a time, and
e100 driver wants access (for examining desc status) simultaneously with
the hardware (which may alter desc status at any time).
On ARM with the previous patch applied it can work because the CPU cache
has the "dirty" bits (e100 driver only reads from the descriptors).
On x86 without swiotlb it can work because streaming allocations are
already coherent.
On x86 with swiotlb it can't really work reliably (and if does, it does
by pure luck) because (I guess) swiotlb has no "dirty" flag and can't
know when it doesn't need to flush.
There is no other fix than to convert the desc rings to coherent
allocs. I'm going to do precisely that in few days, but we're stuck with
the existing code in 2.6.31 (and 2.6.30.x etc).

Would something like passing a mem=xx cmdline on x86_64 be sufficient to test this?

I think so, though I admit I don't remember using this personally since
the introduction of e820 RAM mapping support.
Dmesg will show if the memory is limited. For the swiotlb to effectively
disable no RAM > 0x100000000 may be used.
But this test isn't IMHO terribly important at this point - the driver
makes invalid use of the DMA API and it has to change. The test could
only explain _how_ exactly does it fail, we already know _why_ it does.

Just got a chance to test this for confirmation. When limiting the RAM to 2GB, the patched driver appears to work OK.

Why do you use PCI_DMA_BIDIRECTIONAL? From what i get, the device writes and the
cpu reads - so the direction should be PCI_DMA_FROMDEVICE. Maybe just maybe the
