Hi all, This series only support linux-user emulation. More about LoongArch at: https://github.com/loongson/
The latest kernel: * https://github.com/loongson/linux/tree/loongarch-next Patches need review: * 0002-target-loongarch-Add-core-definition.patch * 0016-target-loongarch-Add-disassembler.patch * 0017-linux-user-Add-LoongArch-generic-header-files.patch * 0018-linux-user-Add-LoongArch-specific-structures.patch * 0019-linux-user-Add-LoongArch-signal-support.patch * 0020-linux-user-Add-LoongArch-elf-support.patch * 0021-linux-user-Add-LoongArch-syscall-support.patch * 0022-linux-user-Add-LoongArch-cpu_loop-support.patch * 0023-linux-user-Add-host-dependency-for-LoongArch-64-bit.patch * 0028-accel-tcg-user-exec-Implement-CPU-specific-signal-ha.patch * 0029-linux-user-Add-safe-syscall-handling-for-loongarch64.patch Changes for v8: * Use the FIELD functions to define cpucfg[i]. * Re-use the decodetree to disassembler description. * Split v7 patch(0017-LoongArch-Linux-User-Emulation.patch). Changes for v7: * scripts/gensyscalls.sh support loongarch64 if we use gensyscalls.sh, we need disable __BITS_PER_LONG at arch/loongarch/include/uapi/asm/bitsperlong.h 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].
