Hi. This is Song Gao's v20 [1], with patch 2 extensively rewritten so that it handles lock_user properly. It compiles, but I need to update the docker image we produced last year so that I can properly test this.
In the meantime, Song, can you please test this? r~ [1] https://lore.kernel.org/qemu-devel/20220624031049.1716097-1-gaos...@loongson.cn/ Song Gao (13): linux-user: Add LoongArch generic header files linux-user: Add LoongArch signal support linux-user: Add LoongArch elf support linux-user: Add LoongArch syscall support linux-user: Add LoongArch cpu_loop support scripts: add loongarch64 binfmt config target/loongarch: remove badaddr from CPULoongArch target/loongarch: Fix missing update CSR_BADV target/loongarch: Fix helper_asrtle_d/asrtgt_d raise wrong exception target/loongarch: remove unused include hw/loader.h target/loongarch: Adjust functions and structure to support user-mode default-configs: Add loongarch linux-user support target/loongarch: Update README configs/targets/loongarch64-linux-user.mak | 3 + linux-user/loongarch64/sockbits.h | 11 + linux-user/loongarch64/syscall_nr.h | 312 ++++++++++++++++ linux-user/loongarch64/target_cpu.h | 34 ++ linux-user/loongarch64/target_elf.h | 12 + linux-user/loongarch64/target_errno_defs.h | 12 + linux-user/loongarch64/target_fcntl.h | 11 + linux-user/loongarch64/target_prctl.h | 1 + linux-user/loongarch64/target_resource.h | 11 + linux-user/loongarch64/target_signal.h | 13 + linux-user/loongarch64/target_structs.h | 11 + linux-user/loongarch64/target_syscall.h | 48 +++ linux-user/loongarch64/termbits.h | 11 + linux-user/syscall_defs.h | 6 +- target/loongarch/cpu.h | 8 +- target/loongarch/helper.h | 2 + target/loongarch/internals.h | 2 + linux-user/elfload.c | 91 +++++ linux-user/loongarch64/cpu_loop.c | 96 +++++ linux-user/loongarch64/signal.c | 335 ++++++++++++++++++ target/loongarch/cpu.c | 34 +- target/loongarch/gdbstub.c | 2 +- target/loongarch/op_helper.c | 10 +- .../insn_trans/trans_privileged.c.inc | 36 ++ scripts/gensyscalls.sh | 2 + scripts/qemu-binfmt-conf.sh | 6 +- target/loongarch/README | 39 +- 27 files changed, 1144 insertions(+), 15 deletions(-) create mode 100644 configs/targets/loongarch64-linux-user.mak create mode 100644 linux-user/loongarch64/sockbits.h create mode 100644 linux-user/loongarch64/syscall_nr.h create mode 100644 linux-user/loongarch64/target_cpu.h create mode 100644 linux-user/loongarch64/target_elf.h create mode 100644 linux-user/loongarch64/target_errno_defs.h create mode 100644 linux-user/loongarch64/target_fcntl.h create mode 100644 linux-user/loongarch64/target_prctl.h create mode 100644 linux-user/loongarch64/target_resource.h create mode 100644 linux-user/loongarch64/target_signal.h create mode 100644 linux-user/loongarch64/target_structs.h create mode 100644 linux-user/loongarch64/target_syscall.h create mode 100644 linux-user/loongarch64/termbits.h create mode 100644 linux-user/loongarch64/cpu_loop.c create mode 100644 linux-user/loongarch64/signal.c -- 2.34.1
