Hi, I read through previous messages which tried to support livepatching in kernel for AArch64. Following is the patch supporting mfentry: https://gcc.gnu.org/ml/gcc-patches/2016-03/msg00756.html And this is the last message about above thread: https://gcc.gnu.org/ml/gcc-patches/2016-04/msg01093.html
Here is another patch trying to support a general option, however. it was not merged either. https://gcc.gnu.org/ml/gcc-patches/2016-12/msg01791.html If I read messages correctly, kernel part is not merged (partly) because of waiting for GCC. As a result, we have to apply local patches, I am wondering if there is any future plan to support it on AArch64, or no one really uses it? I CCed patch authors as well as who joined previous discussions, please let me know if you don't want to be cced in this thread. Thanks, bin
