With this design, if any PCI/IO device is found # to be attached to a numa-node which is not online then the numa-node # id of the corresponding PCI/IO device is set to NUMA_NO_NODE(-1). This # design may negatively impact the performance of PCIe device if the # numa-node assigned to PCIe device is -1 because in such case we may not # be able to accurately calculate the distance between two nodes. # # The multi-controller NVMe PCIe disk has an issue with calculating the # node distance if the PCIe NVMe controller is attached to a PCI host # bridge which has numa-node id value set to NUMA_NO_NODE. This patch # helps fix this ensuring that a cpu/memory less numa node is made online # if it's attached to PCI host bridge. # # Signed-off-by: Nilay Shroff # Reviewed-by: Srikar Dronamraju # Signed-off-by: Michael Ellerman # Link: https://msgid.link/20240517142531.3273464-3-nilay@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 df2b174d5990bc236f9793831b5286940a015a74 # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc866_ads_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc866_ads_defconfig # < make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc866_ads_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc866_ads_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc866_ads_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/powerpc-next_mpc866_ads_defconfig_powerpc-gcc5 # Build took: 0:02:22.026066
