ptrace(PTRACE_GETREGSET, 27642, NT_FPREGSET, 0xffcc67f0) = -1 EINVAL (Invalid argument)
NT_FPREGSET is "2", which the kernel calls NT_PRFPREG. arm64 kernels don't implement this for compat processes, they only support NT_ARM_VFP. If I understand correctly, VFP is hard float, so it seems like this is a bug in gdb: it should only ask for NT_ARM_VFP, not NT_PRFPREG. If I'm mistaken, then the kernel is missing support for compat tasks to issue NT_PRFPREG requests... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1645501 Title: corefiles not created in armhf chroot on arm64 porter To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdb/+bug/1645501/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
