Did you overwrite your tree by mistake ? I pulled riscv-to-apply.next a few days back where this patch along with Anup's priv version fixes are there. But I can't find it anymore. I am looking at this. https://github.com/alistair23/qemu/commits/riscv-to-apply.next I wanted to rebase my sstc series on top of the riscv-to-apply.next. Let me know if I am missing something. > Alistair > > > > > target/riscv/cpu.c | 2 ++ > > target/riscv/cpu.h | 1 + > > target/riscv/insn32.decode | 7 ++++++- > > target/riscv/insn_trans/trans_rvi.c.inc | 16 ++++++++++++++++ > > 4 files changed, 25 insertions(+), 1 deletion(-) > > > > -- > > 2.25.1 > > > > > -- Regards, Atish
