Hi absurdfatalism,
The Prefetchable attribute of any of the PCI BAR in AWS F1 cannot be modified by the software.
AWS F1 support the BARs and their attributes listed in the link below
https://github.com/aws/aws-fpga/blob/master/hdk/docs/AWS_Fpga_Pcie_Memory_Map.md
The setting MAX_EXTRA_ADJ under sdk/linux_kernel_drivers/xdma/libxdma.h is unrelared to the BAR prefetchable attribute.
Thanks,
Sunil.
