Xilinx likely doesn't won't respond and might delete this post.

If you want to help get the compilation infrastructure and help on my fork, i will gladly review. An example is show to test qdma for different kernel versions

I have tested your xvsec patch on Linux v6.3 with firesim on Xilinx VCU118 Board, but I have some issues.

Although it was compiled successfully, the system stops responding when I use firesim infrasetup, which uses xvsecctl to replace the bitstream. If I restart the system (without power cycle FPGA) this time, it stops at BIOS. But when I switch to Kernel v5.4 or v5.15, it works normally.
