Hi All, This series add support linux-user emulation. As the LoongArch kernel had merged into 5.19-rc1, you can see the latest kernel at https://kernel.org
Need review patches: 0002-linux-user-Add-LoongArch-signal-support.patch 0007-target-loongarch-remove-badaddr-from-CPULoongArch.patch 0008-target-loongarch-Fix-missing-update-CSR_BADV.patch 0009-target-loongarch-Fix-helper_asrtle_d-asrtgt_d-raise-.patch 0010-target-loongarch-remove-unused-include-hw-loader.h.patch 0011-target-loongarch-Adjust-functions-and-structure-to-s.patch V17: - Split v16 patch7 to patch7-11, and fix some bugs for system-mode; - Update signal.c, add parse_extcontext(); - Add get_elf_hwcap(), and ELF_PLATFORM. V16: - Update signal.c; - Update helper_rdtime_d(); - Update scripts/gensyscalls.sh, fixed a warning. v15: - Rebase; - Update README; - Adjust some functions and structure to support user-mode; - Update syscall; - Update target_sigcontext; Old series: - https://patchew.org/QEMU/20220614090536.1103616-1-gaos...@loongson.cn/ Test: - user-mode: make check && make check-tcg && run LoongArch bash - system-mode make check && make check-tcg Thanks.
