ERROR:../qemu-7.0.0/accel/tcg/cpu-exec.c:933:cpu_exec: assertion failed: (cpu == current_cpu)`. Looking at the code, that code is wrapped in a gcc/clang ifdef.

Commands such as `ls` work fine, while `apt-get` will immediately crash with the error listed above. - -Note that this happens running Asahi Linux on the bare metal of an M1-based Macbook Pro. This same issue does *not* occur running the *same* binaries with the *same* x86_64 Ubuntu image on an Arch or Ubuntu VM under macOS on the same machine - regardless of if the QEMU binaries were built in a VM or in Asahi. - -These are big.LITTLE chips. Using taskset/affinity to limit the target process to a single specific core does not help. The Asahi kernel has a 16K page-size, which is known to cause trouble for some programs. qemu-arm(-static) however works without any issues (the M1 cannot run 32-bit ARM code natively, only 64-bit).""" -reproduce = "n/a" -additional = "n/a" diff --git a/gitlab/issues/target_missing/host_arm/accel_TCG/1714.toml b/gitlab/issues/target_missing/host_arm/accel_TCG/1714.toml deleted file mode 100644 index 9c70f80a0..000000000 --- a/gitlab/issues/target_missing/host_arm/accel_TCG/1714.toml +++ /dev/null @@ -1,39 +0,0 @@ -id = 1714 -title = "QEMU crashes on ARMv7 since at least commit 493c9b19" -state = "closed" -created_at = "2023-06-18T16:06:16.540Z" -closed_at = "2024-02-14T15:45:11.632Z" -labels = ["Closed::Fixed", "accel: TCG", "host: arm"] -url = "https://gitlab.com/qemu-project/qemu/-/issues/1714" -host-os = "Android" -host-arch = "ARMv7a" -qemu-version = "7.2.50 .. 8.0.0 .. 8.0.2 .. master" -guest-os = "TinyCore Linux 12" -guest-arch = "x86" -description = """I'm trying to build QEMU for Android, Arm64 versions work well, but **Armv7** builds began to crash nearly since this series of commits (QEMU 7.2.50), related to 'TCG_TARGET_HAS_direct_jump' removal by @rth7680. -More precisely, this commit still works: - -https://gitlab.com/qemu-project/qemu/-/commit/82df11e78d0baef7ffb7e7933c6fb830ffed087c - -and this one crashes: - -https://gitlab.com/qemu-project/qemu/-/commit/493c9b19a7fb7f387c4fcf57d3836504d5242bf5 - -(I tracked commits of 'tcg' subfolder and didn't bisect finer, but it's possible if needed). - -Both qemu-system-x86_64 and qemu-system-i386 emulators crash. - -**The crash is related to translation buffer size** : if I don't specify "-accel tcg,thread=single **,tb-size=256** ", the machine works. - -The problem is that I can not run debugger on a phone, and crash dump does not show any useful information, just "segfault" reason ("Fatal signal 11 (SIGSEGV), code 2 (SEGV_ACCERR), fault addr 0xe19b8000"). - -Even more, the Linux starts and runs, but it crashes only when I'm trying to run the GIMP, between splash screen and main interface appearance. - -I know that 1) Android is not officially supported and 2) 32-bit hosts were considered deprecated recently, but maybe it's possible to do something with these crashes? - -Recent master (https://gitlab.com/qemu-project/qemu/-/commit/5692a39f329413a00020a61fff95aff6b9884a73) doesn't work as well. -All 8.0.x Arm64 builds are runnable. - -Thanks in advance.""" -reproduce = "n/a" -additional = "n/a" diff --git a/gitlab/issues/target_missing/host_arm/accel_TCG/2295.toml b/gitlab/issues/target_missing/host_arm/accel_TCG/2295.toml deleted file mode 100644 index 8823c2251..000000000 --- a/gitlab/issues/target_missing/host_arm/accel_TCG/2295.toml +++ /dev/null @@ -1,16 +0,0 @@ -id = 2295 -title = "Support Apple Silicon acceleration for x86 / x86_64 guests" -state = "closed" -created_at = "2024-04-20T09:43:57.794Z" -closed_at = "2024-04-29T12:44:12.132Z" -labels = ["accel: TCG", "host: arm", "hostos: macOS", "kind::Feature Request"] -url = "https://gitlab.com/qemu-project/qemu/-/issues/2295" -host-os = "n/a" -host-arch = "n/a" -qemu-version = "n/a" -guest-os = "n/a" -guest-arch = "n/a" -description = "n/a" -reproduce = "n/a" -additional = """* [Top-level discussion on UTM downstream](https://github.com/utmapp/UTM/issues/5460) -* [Discussion on memory access instructions on UTM downstream](https://github.com/utmapp/UTM/issues/2366)""" |
