Hi All,
This series adds 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 patch:
0002-linux-user-Add-LoongArch-signal-support.patch
V19:
- Update signal.c, add fpu info, fpu_context and end info to
target_rt_sigframe.
V18:
- Update signal.c, add set fpu_context'magic, update parse_extcontext()
and remove some cast.
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;

Test:
make check && make check-tcg && run LoongArch bash
Thanks.
