The primary contributor to the stack # usage seems to be openvswitch, which is used by OVN-Kubernetes (based on # OVN (Open Virtual Network)), but NFS also contributes in some stack # traces. # # There may be some opportunities to reduce stack usage in the openvswitch # code, but doing so potentially require tradeoffs vs performance, and # also requires testing across architectures. # # Looking at stack usage across the kernel (using -fstack-usage), shows # that ppc64le stack frames are on average 50-100% larger than the # equivalent function built for x86-64. Which is not surprising given the # minimum stack frame size is 32 bytes on ppc64le vs 16 bytes on x86-64. # # So increase the default stack size to 32KB for the modern 64-bit Book3S # platforms, ie. pseries (virtualised) and powernv (bare metal). That # leaves the older systems like G5s, and the AmigaOne (pasemi) with a 16KB # stack which should be sufficient on those machines. # # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Signed-off-by: Aneesh Kumar K.V (IBM) <aneesh.kumar@kernel.org> # Link: https://msgid.link/20231215124449.317597-1-mpe@ellerman.id.au # < /opt/cross/kisskb/korg/gcc-12.2.0-nolibc/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-12.2.0-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 18f14afe281648e31ed35c9ad2fcb724c4838ad9 # make -s -j 40 ARCH=s390 O=/kisskb/build/powerpc-fixes_defconfig_s390x-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/s390-linux/bin/s390-linux- defconfig # Added to kconfig CONFIG_DEBUG_INFO_BTF=n # Added to kconfig # < make -s -j 40 ARCH=s390 O=/kisskb/build/powerpc-fixes_defconfig_s390x-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/s390-linux/bin/s390-linux- help # make -s -j 40 ARCH=s390 O=/kisskb/build/powerpc-fixes_defconfig_s390x-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/s390-linux/bin/s390-linux- olddefconfig .config:3757:warning: override: reassigning to symbol DEBUG_INFO_BTF # make -s -j 40 ARCH=s390 O=/kisskb/build/powerpc-fixes_defconfig_s390x-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/s390-linux/bin/s390-linux- Completed OK # rm -rf /kisskb/build/powerpc-fixes_defconfig_s390x-gcc12 # Build took: 0:02:56.730685
