Hi all!
I am porting PLX driver for PEX 8619 to a power8 machine with CentOS-7.3.
The PEX 8619 is used as an NTB (Non-Transparent Bridge).
First, two DMA buffer are allocated with dma_alloc_coherent() and the
physical address are:
src: 0x 00000000_60600000
dst: 0x 00000000_60800000
Then, a DMA transfer is started and an EEH is reported in dmesg.
This DMA test is OK at an x86_64 platform.
Here are the details. Any suggestion is appreciated!

Please check if memory physical address (instead of DMA address) is used
in the driver. The EEH error is caused by DMA address 0x60600000 and it's
not having a corresponding TCE entry.
Thanks,
Gavin

Thanks for your replay.
I fixed my test according your suggestion. The CPU physical addresses (0x
1f9e400000 and 0x 1f82c00000) converted with virt_to_phys() are used ,
instead of DMA addresses, or BUS physical addresses (0x 60a00000 and 0x
60c00000). However, EEH still reports error.

That's incorrect. The system has an IOMMU, only addressed properly
mapped/translated by the IOMMU can be used for DMA. That is addresses
returned by things like dma_map_single/sg, dma_alloc_coherent, etc...
You also need to ensure you configure a proper dma mask.
Using virt_to_phys() is NEVER correct on *any* architecture.
Cheers,
Ben.

Ben is correct that PCI device needs to use DMA address instead of
memory address. I was suggesting to ensure that in the driver's code
and was misunderstood. It seems the driver has used the DMA address,
which is correct. But it seems the TCE entry for the DMA address isn't
built correctly. Could you please share the kernel log with original
driver code? I am not sure if I can find somethere there, but worthy
to check.
Thanks,
Gavin

I did another test:
- Call dma_set_mask_and_coherent(&pPciDev->dev, DMA_BIT_MASK(32)) in probe;
- Use DMA address or BUS address in DMA
But EHH error remains.
All sources are based on PLX SDK 7.25.
Note: Sample test is in user space. It allocates memory and starts DMA
through PLX API.
The original sample NT_DmaTest does DMA between BARx and Host memory.
I change this for simple: Allocate two host memory buffers and try to do DMA
between them.

We need to dig out the details of the EEH error. It will tell us
more precisely what is happening.
Note also that if your device can do 64-bit addresses, you should use
a 64-bit mask, it will result in more efficient transfers. However, we
should first investigate the problem with 32-bit because it seems to
indicate that you might be DMA'ing beyond your buffer.
Another possibility would be if the requests from the PLX have a
different initiator ID on the bus than the device you are setting up
the DMA for.

Is there a way to check out the initiator ID in the driver? I'd like to make
sure of this.

If you are running bare metal (ie, not under any hypervisor, aka
"powernv" platform), the EEH error log will contain a register dump. If
you paste that to us, we might be able to decode it, it will tell us
more data about the cause of the failure, including possibly the
initiator of the failing transaction.
The initiator ID (aka RID, aka bus/device/fn) of the DMA packets must
match the ones of the struct pci_dev you are using to establish the
mapping.
Cheers,
Ben.

Here is the problem, I think.
There are three PEX 8619 devices given in lspci, and there are
supported by two different modules:
