image this is my result ,after installing the driver module. It seems to works fine in riscv, but the bandwidth is very slow. I write a fpga program to test the bandwidth ,this is my result on x86 and riscv.

bf53299697751171aa5f0b8abfb7b84 x86 on the left, while riscv on the right. x86 cpu is i9-12900K, riscv cpu is SOPHON SG2042. The performance gap between them is too large,what is the reason? any reason about cpu performance?
