TDA4VE-Q1: PCIe Switch causes nvme timeouts

Philipp S.
Prodigy 10 points

Part Number: TDA4VE-Q1
Other Parts Discussed in Thread: TDA4VM

My setup is the Phytec Izar Development Board with a TI Jacinto TDA4VE SoC (Arm Cortex A72 cores): phyBOARD-Izar | PHYTEC

I connected a Microchip PCI1005 Switch to the board with the goal to connect more than one ssd.

On the SoC we run embedded linux, Kernel Version 6.12. 

We experience the following behaviour:

  • TDA4VM Eval Board: up to 3 SSD work fine, the 4th produces a nvme timeout during boot
  • TDA4VE Izar Board: with the switch no SSD works fine, also 1 produces a nvme timeout
  • TDA4VE Izar Board and one SSD directly to the Board works fine
  • TDA4VE Izar Board with switch and network cards works fine

The nvme timeouts are blocking the processor for approximatly 10mins. After that the ssd is listed under lspci, but is not accessible.

log.txt 

The problem seems to be pcie switch + nvme SSDs.

In the TRM i found Address Translation Services (ATS)  under not supported features for the TDA4VE; the TDA4VM supports it. Could this be a reason?

Does anyone has other ideas?

Thank you for your support.

    Hi Philipp,

    Before I comment about the ATS suspicion, can I get the output from "lspci -vvv"?

    Otherwise, for TDA4VM, there is a known issue with PCIe switches. TDA4VE, there are no known issue, as a silicon errata that affected TDA4VM has been fixed for TDA4VE. For reference, errata for TDA4VM mentioned in this FAQ if you would like details:  [FAQ] J721EXSOMXEVM: How to work around errata i2086 for PCIe switches and multifunction devices for J721E/TDA4VM/DRA829?  

    Regards,

    Hi Takuma, 

    attached is the lspci log.

    log_lspci.txt

    I stumbled across the TDA4VM errata when I first tested some switches with it. 

    Regards,

    Philipp

    Hi Philipp,

    Thanks for the logs. It looks like ATS capabilities are not advertised for the NVMe as well as the PCIe switch, and the ATS capabilities of the SoC is disabled. So, I don't expect ATS to be causing an issue.

    Instead, it looks like ErrorSrc for the uncorrectable error is 0220 (bus 2, device 4) which corresponds to one of the PCIe switch device, and that particular PCIe switch instance has a HeaderLog from bus 5, which corresponds to the NVMe device. And the error that is flagged at the PCIe switch is a "UnsupReq+", so this is being propagated up to the PCIe controller. 

    So, this issue looks similar to the errata i2086 for TDA4VM, but different in the sense that it is not triggering a bus error. Which means the workaround in the FAQ will probably not have much effect. However, since the error is being flagged as part of the AER, perhaps we can ignore this error trigger. As a side note, the Unsupported Request is common when probing the PCIe bus to see which addresses are populated when a PCIe switch is connected, but what is not common is for it to be flagged as an uncorrectable error. 

    • As an experiment, could you try adding "pci=noaer" in Linux kernel commandline?

    Regards,

    Takuma

    Hi Takuma,

    thank you for the detailed explanation. I tried setting pci=noaer but i think it did not have any effect, log is attached.

Welcome to Buildroot

    Do you have other ideas to solve the issue? Perhaps ignoring the error via a kernel patch?

    Regards,

    Hi Philipp,

    Can you also post the "lspci -vvv" output again with the "pci=noaer" in place?

    Regards,

    Hi Takuma, 

    log is attached.

    Hi Philipp,

    Thanks for the logs. Looking through them, it looks like at the PCIe controller level, the errors look clean (that is, errors are not propagated), but the error still happens at the switch and NVMe level. Although ATS is not available for J721S2, perhaps the issue is still related to some address translation.

    As an experiment, can you try also putting the "iommu.passthrough=1" in kernel argument as well?

    Additionally, do you have other NVMe devices that you could test to see if this is an issue with the specific NVMe device from Swissbit, or an issue with other NVMe devices as well (preferably a NVMe card from a different vendor)?

    Regards,

    Takuma
