Antigravity ssh remote failed

ssh 到 raspberry pi 都會失敗，但是連到 GB10 是 OK的。
到 pi 的 ~/.antigravity 去看 log: 在 data/logs/20260104T124620/remoteagent.log 有 SIGILL

Language server killed with signal SIGILL

找到一個很像 language server 的 : ./bin/94...af/extensions/antigravity/bin/language_server_linux_arm
run run 看真的 fail

~/.antigravity-server $ ./bin/94f...6af/extensions/antigravity/bin/language_server_linux_arm --version
Illegal instruction

所以用 gdb 來看，用這些參數：

   * `-ex "run"`: Tells GDB to start the program immediately.
   * `-ex "x/i \$pc"`: This is the most important part.
       * x = Examine memory.
       * /i = Format the output as a CPU instruction.
       * $pc = Look at the Program Counter (the exact address where the CPU stopped because of the error).
   * `-ex "bt"`: Generates a Backtrace to show the function call stack leading up to the crash.
   * `--batch`: Runs GDB in non-interactive mode and exits once the commands are finished.
   * `--args`: Allows you to pass the binary path and any flags it needs (like --version).

結果

~/.antigravity-server $gdb -ex "run" -ex "x/i \$pc" -ex "bt" --batch --args ./bin/94...6af/extensions/antigravity/bin/language_server_linux_arm --version

Program received signal SIGILL, Illegal instruction.
0x000000555d5426ac in ?? ()

#2  0x0000007ff7fd83a0 in ?? () from /lib/ld-linux-aarch64.so.1

所以是 ldaddal
查這個 instruction 要ARMv8.1 LSE, raspberry pi 4 是 ARMv8.0，所以沒辦法。
另外用 VSCode 測試，ssh 到 raspberry pi 是 OK 的，髓以猜是language server 重新 compile for armv8.0 應該就可以....
然後 .vscode 沒有 language_server... 這個東西，連 bin 都沒有...
