[PATCH v11 00/26] Add LoongArch linux-user emulation support
Posted by Song Gao 10 months, 1 week ago
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:
  * 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

Changes for v11:
  * Clean up insns.decode.  

Changes for v10:
  * Delete format_insn(), use output_XXX.

Changes for v9:
  * Use GPL-2.0+ SPDX license identifier.
  * Move set_loongarch_cpucfg() in loongarch_3a5000_initfn().
  * target/loongarch/insn_trans/trans_xxx.c rename to
    target/loongarch/insn_trans/trans_xxx.c.inc.
  * Split host_signal_pc and host_signal_write out of user-exec.c.

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

V10:https://patchew.org/QEMU/1636700049-24381-1-git-send-email-gaosong@loongson.cn/
V9: https://patchew.org/QEMU/1636340895-5255-1-git-send-email-gaosong@loongson.cn/

V7: https://patchew.org/QEMU/1634561247-25499-1-git-send-email-gaosong@loongson.cn/

Please review!

Thanks.
