Hi, PCI-E atomics don't work for me with a Thunderbolt 3 bridge. I see the following message from my Thunderbolt 3 eGPU in dmesg: kfd: skipped device 1002:67df, PCI rejects atomics Hardware is a Dell XPS 13 9370 (with i7-8550U CPU) connected to a Zotac AMP mini, with an AMD RX 570 graphics card. Due to this, I cannot use the GPU for OpenCL, because the compute stack requires PCI-E atomics support [1]. What could be the problem? Is this a hardware limitation or a missing feature in the Linux TB driver? [1] https://github.com/RadeonOpenCompute/ROCm/issues/157 Best regards, Tim ps.
