Subject: [PATCH v4 00/21] Add LoongArch linux-user emulation support
Date: Thu,  2 Sep 2021 20:40:46 +0800	[thread overview]
Message-ID: <1630586467-22463-1-git-send-email-gaosong@loongson.cn> (raw)

Hi,

We tested some basic system commands using LoongArch clfs system.
and supported 'make check-tcg'. Of course. this series only support linux-user emulation.
 

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].

    [2]: https://patchew.org/QEMU/20210823195529.560295-1-richard.henderson@linaro.org/


Changes for v2:
  * Patch 1, remove unnecessary introduction;
  * Patch 3, follow the ARM/AVR pattern to add new CPU features;
  * Patch 6, remove decode_lsx(); 
  * Patches 7-18, delete opcode definition, modify translation function;
  * Patches 20-22, split V1 patch20 to V2 patch20-22.

V3: https://patchew.org/QEMU/1630048494-2143-1-git-send-email-gaosong@loongson.cn/
V2: https://patchew.org/QEMU/1626861198-6133-1-git-send-email-gaosong@loongson.cn/
V1: https://patchew.org/QEMU/1624881885-31692-1-git-send-email-gaosong@loongson.cn/

Please review!

Thanks.
