CPU family 6, model 60 indicates the Haswell family, which did have AVX support. But additionally this is the Intel Pentium CPU G3220 which did not support AVX and AVX2.
I can repro the SIGILL using qemu: $ qemu-x86_64 -cpu Haswell,-avx,-avx2 /usr/bin/ghostty +version qemu-x86_64: warning: TCG doesn't support requested feature: CPUID[eax=07h,ecx=00h].EBX.hle [bit 4] qemu-x86_64: warning: TCG doesn't support requested feature: CPUID[eax=07h,ecx=00h].EBX.rtm [bit 11] qemu: uncaught target signal 4 (Illegal instruction) - core dumped Illegal instruction (core dumped) qemu-x86_64 -cpu Haswell,-avx,-avx2 /usr/bin/ghostty +version OTOH, zig does not fail: $ qemu-x86_64 -cpu Haswell,-avx,-avx2 /usr/bin/zig version qemu-x86_64: warning: TCG doesn't support requested feature: CPUID[eax=07h,ecx=00h].EBX.hle [bit 4] qemu-x86_64: warning: TCG doesn't support requested feature: CPUID[eax=07h,ecx=00h].EBX.rtm [bit 11] 0.15.2 This is probably because we use -DZIG_TARGET_MCPU=baseline while building zig. We should try to add -mcpu baseline while building Ghostty. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2148769 Title: ghosty does not start: Illegal instruction To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ghostty/+bug/2148769/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
