The port is available here: https://github.com/plctlab/plct-qemu/tree/plct-pm-fix-v7 v2: * drop some error patchs * Add patch 2 and 3 to fix the new problems * Add patch 4 and 5 to use PC-relative translation for pointer mask for instruction fetch v3: * use target_pc temp instead of cpu_pc to store into badaddr in patch 3 * use dest_gpr instead of tcg_temp_new() for succ_pc in patch 4 * enable CF_PCREL for system mode in seperate patch 5 v4： * Fix wrong pc_save value for conditional jump in patch 4 * Fix tcg_cflags overwrite problem to make CF_PCREL really work in new patch 5 * Fix tb mis-matched problem in new patch 6 v5: * use gen_get_target_pc to compute target address of auipc and successor address of jalr in patch 4. * separate tcg related fix patches(5, 6) from this patchset v6: * rename gen_get_target_pc as g in patch 3 and patch 4 * use gen_pc_plus_diff to compute successor address of jal in patch 4 * mov comments for patch 5 to patch 4 v7: * separate support for PC-relative translation and pointer mask for instruction fetch (patch 3~6) out of this patchset Weiwei Li (2): target/riscv: Fix pointer mask transformation for vector address target/riscv: Update cur_pmmask/base when xl changes target/riscv/csr.c | 9 ++++++++- target/riscv/vector_helper.c | 2 +- 2 files changed, 9 insertions(+), 2 deletions(-)
