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-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-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_mpc85xx_defconfig+KVM_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc85xx_defconfig Using /kisskb/src/arch/powerpc/configs/mpc85xx_base.config as base Merging /kisskb/src/arch/powerpc/configs/85xx-32bit.config Merging /kisskb/src/arch/powerpc/configs/85xx-hw.config Merging /kisskb/src/arch/powerpc/configs/fsl-emb-nonhw.config # # merged configuration written to .config (needs make) # # Added to kconfig CONFIG_PPC_E500MC=y # Added to kconfig CONFIG_VIRTUALIZATION=y # Added to kconfig CONFIG_KVM_E500MC=y # Added to kconfig # < make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc85xx_defconfig+KVM_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc85xx_defconfig+KVM_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4597:warning: override: reassigning to symbol PPC_E500MC .config:4598:warning: override: reassigning to symbol VIRTUALIZATION # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc85xx_defconfig+KVM_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/include/linux/build_bug.h:5, from /kisskb/src/include/linux/container_of.h:5, from /kisskb/src/include/linux/list.h:5, from /kisskb/src/include/linux/module.h:12, from /kisskb/src/drivers/net/ethernet/freescale/fs_enet/mac-scc.c:15: /kisskb/src/drivers/net/ethernet/freescale/fs_enet/mac-scc.c: In function 'allocate_bd': /kisskb/src/include/linux/err.h:28:49: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] 28 | #define IS_ERR_VALUE(x) unlikely((unsigned long)(void *)(x) >= (unsigned long)-MAX_ERRNO) | ^ /kisskb/src/include/linux/compiler.h:77:45: note: in definition of macro 'unlikely' 77 | # define unlikely(x) __builtin_expect(!!(x), 0) | ^ /kisskb/src/drivers/net/ethernet/freescale/fs_enet/mac-scc.c:138:13: note: in expansion of macro 'IS_ERR_VALUE' 138 | if (IS_ERR_VALUE(fep->ring_mem_addr)) | ^~~~~~~~~~~~ /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8544ds.dtsi:154.11-204.6: Warning (interrupt_provider): /pcie@e000b000/pcie@0/uli1575@0/isa@1e: '#interrupt-cells' found, but node is not an interrupt provider arch/powerpc/boot/dts/fsl/mpc8544ds.dtb: Warning (interrupt_map): Failed prerequisite 'interrupt_provider' /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8572ds.dtsi:375.11-425.6: Warning (interrupt_provider): /pcie@ffe08000/pcie@0/uli1575@0/isa@1e: '#interrupt-cells' found, but node is not an interrupt provider arch/powerpc/boot/dts/fsl/mpc8572ds.dtb: Warning (interrupt_map): Failed prerequisite 'interrupt_provider' Completed OK # rm -rf /kisskb/build/powerpc-next_mpc85xx_defconfig+KVM_powerpc-gcc13 # Build took: 0:03:02.132074
