Hi, I want to know about how to flush dirty datas to the Memory at XiangShan.
Are there some specific instructions or registers?

Thanks.

Currently, XiangShan does not have a way to flush dirty data to memory directly.

RISC-V provides ISA extensions such as Zicbom, Zicbop, Zicboz to manage cache, but XiangShan does not yet support these extensions. Please check RISC-V Base Cache Management Operation ISA Extensions or RISC-V CMO TG for more information.
