Hi, The 'o32' code has been deleted at the latest kernel [1]. This series only support linux-user emulation. More about LoongArch at: https://github.com/loongson/ [1] https://github.com/loongson/linux/tree/loongarch-next Missing review: * 0001-target-loongarch-Add-README.patch * 0002-target-loongarch-Add-core-definition.patch * 0017-LoongArch-Linux-User-Emulation.patch Changes for v6: * Resolve patch10 and patch6 code issues. Changes for v5: * Follow Richard's code review comments [1]. * Use force_sig_fault(). * Implement setup_sigtramp. [1]: https://patchew.org/QEMU/1630586467-22463-1-git-send-email-gaos...@loongson.cn/ Changes for v4: * Update README，add LoongArch linux-user emulation Introduction. * Add 'make check-tcg' support(patch 20). * Add binfmt config(patch 21). * Fix bugs when running loongarch basic commands. Changes for v3: * Split trans.inc.c. * Remove csr registers. * Delete patchs 2, 4, 5. * Follow Richard's code review comments [1]. * Follow Richard's riscv patches [2].
