| 3 | According to the "The RISC-V Instruction Set Manual Volume I: Unprivileged | 3 | I improve compatibility with RV32 and RV64 by adjusting the FIELD definition |
| 4 | Architecture" Version 20240411, Section 31.3.4 "Vector type register, vtype", | 4 | of vtype.vill. |
| 5 | and Table 40 "vtype register layout", this patch adds the definition for the | ||
| 6 | vill field of the vtype register. The bit position for vill is [63]. | ||
| 7 | 5 | ||
| 8 | This change ensures that our implementation remains in line with the latest | 6 | PATCH v1: |
| 9 | RISC-V specifications, thereby maintaining compatibility and correctness. | 7 | https://lore.kernel.org/qemu-devel/cover.1733922709.git.lc00631@tecorigin.com/T |
