Hi all, I have a question regarding the configuration of vector lengths for the RISC-V V extension in Gem5. I know that for ARM SVE, Gem5 provides options such as 'system.sve_vl' and 'system.cpu[:].isa[:].sve_vl_se' to set the vector length. However, I am curious if there are any analogous settings available for customizing the vector length of the RISC-V V extension. I would greatly appreciate any help. Best regards, Xiaokang

Hi Xiaokang, You can set the vlen parameter of the RiscvISA object to change the vector length. https://github.com/gem5/gem5/blob/stable/src/arch/riscv/RiscvISA.py#L101 Regards, Hoa Nguyen On Wed, Mar 27, 2024, 21:47 Xiaokang Fan via gem5-users <gem5-users@gem5.org> wrote: > Hi all, > > I have a question regarding the configuration of vector lengths for the > RISC-V V extension in Gem5. > > > I know that for ARM SVE, Gem5 provides options such as 'system.sve_vl' and > 'system.cpu[:].isa[:].sve_vl_se' to set the vector length.

Hi Hoa I tried the 'vlen' option, it worked. Thanks a lot!
