It doesn't seem QEMU supports ISA 2.05 for any 32bit PowerPC (only POWER7 and above, that are 64bit processors). ** Tags removed: linux-user -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1926202 Title: qemu-user can't run some ppc binaries Status in QEMU: New Bug description: qemu-user v6.0.0-rc5, built in static mode, will crash for certain ppc binaries. It seems to have something to do with glibc for some Centos versions. The problem is easiest to see with statically-linked binaries. The attached Dockerfile shows how to produce a ppc binary that will crash qemu-user. Here is how to reproduce the problem: $ uname -m x86_64 $ docker run --rm --privileged multiarch/qemu-user-static --reset -p yes $ docker build -t qemu-bug:centos -f Dockerfile.centos . $ docker run --rm -it -v$PWD:$PWD -w$PWD qemu-bug:centos cp /helloworld-centos.static.ppc . $ qemu-ppc-static --version qemu-ppc version 5.2.95 (v6.0.0-rc5) Copyright (c) 2003-2021 Fabrice Bellard and the QEMU Project developers $ qemu-ppc-static ./helloworld-centos.static.ppc emu: uncaught target signal 4 (Illegal instruction) - core dumped [1] 16678 illegal hardware instruction (core dumped) qemu-ppc-static ./helloworld-centos.static.ppc To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1926202/+subscriptions
