| kata-irc-bot | <manabu.sugimoto> The guest kernel uses `-O2` (`CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE`) by default as well as the upstream kernel. You can use `export KCFLAGS=-O3` if you want to, but `-O3` has a long history of generating worse code than `-O2` as mentioned in https://lore.kernel.org/lkml/CA+55aFz2sNBbZyg-_i8_Ldr2e8o9dfvdSfHHuRzVtP2VMAUWPg@mail.gmail.com/. | 02:04 |
