We're using qemu 8.1.0. Whilst I will get us updated to 8.1.2 and see if that helps, I think those commits are in 8.1.0:
$ git show cb62bd15e14e304617d250158b77d0deb032f03 commit cb62bd15e14e304617d250158b77d0deb032f032 Author: Richard Henderson <richard.henderson@linaro.org> Date: Thu Jul 6 08:45:13 2023 +0100
accel/tcg: Split out cpu_exec_longjmp_cleanup [...] $ git tag --contains cb62bd15e14e304617d250158b77d0deb032f03 v8.1.0 v8.1.0-rc0 v8.1.0-rc1 v8.1.0-rc2 v8.1.0-rc3 v8.1.0-rc4 v8.1.1 v8.1.2
Similarly for:
commit deba78709ae8ce103e2248413857747f804cd1ef Author: Richard Henderson <richard.henderson@linaro.org> Date: Thu Jul 6 17:55:48 2023 +0100
accel/tcg: Always lock pages before translation
and
commit ad17868eb162a5466d8ad43e5ccb428776403308 Author: Richard Henderson <richard.henderson@linaro.org> Date: Wed Jul 26 12:58:08 2023 -0700
accel/tcg: Clear tcg_ctx->gen_tb on buffer overflow [...] Fixes: deba78709ae8 ("accel/tcg: Always lock pages before translation")
Both of which are also in 8.1.0.
Is there any other patch related to those we might be missing?
Cheers,
Richard
