Hello Jim,

Could you perhaps test this series:
https://lore.kernel.org/linux-pci/20251127170908.14850-1-18255117159@xxxxxxx/


Since the series above only defaults by setting MPS to MPSS for the
Root Port (and no other devices), for kernels with PCIE_BUS_SAFE=y
pcie_bus_configure_settings() will still be called for each downstream
device, so it should not affect your CM product.

But, it would be nice if you could test the series anyway, just to
verify.


Kind regards,
Niklas
