This would be evident in "lspci -vvv" I think? osstest doesn't collect

I thought I could figure it out from the serial logs of dom0 booting,
but I'm not seeing it. I'll see if I can borrow the machine and get back
to you.

BTW, I just noticed a shed load of

Here we go. The device in question is:

There are 64-bit bars but they don't have addresses >4G so I think they

Any idea where I can find the DMA mask?

Full lspci below.

If a device only has 32-bit BARs it's generally not capable of handling
64-bit DMA addresses and we can point and laugh at the card.

mptsas is a driver that uses dma_get_required_mask() to determine a
"suitable" DMA mask -- but under Xen dma_get_required_mask() may return
the wrong mask since it only gets the physical RAM range and not machine
addresses.

Is this the smoking gun then? Do we have any idea what to do about it?

This is still failing with zillions of this message
  Mar 27 12:25:48.036598 [  850.054546] mptsas 0000:03:00.0: swiotlb buffer is full

Are we any closer to figuring out how to get a fix for this past the
x86 maintainers ?

Does the Linux kernel not have a "no regressions" policy ?  This is a
regression, after all...

Thanks,
Ian.

Another week has gone by and Linux tip still fails this test.

Yes, You've not fixed it yet.

My understanding from private emails is that the problem is mostly
political rather than technical.

I'm not familiar with the Linux kernel's VM system.  However, if
someone would write a patch which provides an arch override for this
(which from the private emails seems like is what required and would
not be too hard for someone who knew what they were doing), then I can
try to do the political work of negotiating with the Linux community.

For this specific problem with the mptsas driver, yes.  But there other
problems with swiotlb usage such as by skbs using compound pages.

We (XenServer) plan to fix all these by making use of the IOMMU. See
Malcolm's recent design doc.  This is still quite a ways off though.

This fix doesn't require any particular knowledge of the VM subsystem
and there's already some infrastructure for providing an arch specific
implementation of dma_get_required_mask().
