2.1.2.7. PCIe* x4 cores may report Uncorrectable Fatal Error or Malformed TLP

Description

In the R-tile Intel® FPGA IP for PCIe* , the 2nd and 3rd PCIe* x4 cores (x4core_0 and x4core_1) fail the atomic address alignment check when the Processing Hints is not 0 and the TLP Hints bit is not set. This failure is reflected as Uncorrectable Fatal Error or Malformed TLP. The PCIe* x16 core and x8 core are not affected as the Processing Hints is stripped off when TLP Hints bit is not set during an atomic address alignment check.

Impacted PCIe* Hard IP Modes

  • Endpoint
  • Root Port
  • TL Bypass

Workaround

You must not send non-zero Processing Hints when TLP Hints bit is not set.
