2024-04-01Unify VM code Rishiyur S. Nikhil2-0/+1146
Old vmem code had much 'cut-and-paste' replication for RV32 (Sv32) and (#408) RV64 (Sv39, Sv48), and was scattered over several files. New code unifies them into single set of parameterized functions that works for RV32/RV64 and Sv32/Sv39/Sv48 (and is ready for Sv57). Deleted old files: riscv_vmem_rv32.sail riscv_vmem_rv64.sail riscv_vmem_sv32.sail riscv_vmem_sv39.sail riscv_vmem_sv48.sail riscv_pte.sail riscv_ptw.sail Current files: all named riscv_vmem_* riscv_vmem.sail (root file for vmem) riscv_vmem_common.sail riscv_vmem_pte.sail riscv_vmem_ptw.sail riscv_vmem_tlb.sail riscv_vmem_types.sail Modified top-level Makefile accordingly. Added documentation on new vmem code: doc/notes_Virtual_Memory.adoc
2023-06-15Run the pre-commit hook on all filesAlex Richardson2-2/+2
This strips trailing whitespace and fixes line endings. I had to add the *.dump files to the exclude list to avoid excessive changes, but ideally these would not be part of the repository since they can just be generated by running objdump manually.
