This is especially true for # pmem devices. If the target node of the pmem device is not online, we # find the nearest online node to the device and associate the pmem device # with that online node. To find the nearest online node, we should have # the numa distance table updated correctly. Update the distance # information during the device probe. # # For a papr scm device on NUMA node 3 distance_lookup_table value for # distance_ref_points_depth = 2 before and after fix is below: # # Before fix: # node 3 distance depth 0 - 0 # node 3 distance depth 1 - 0 # node 4 distance depth 0 - 4 # node 4 distance depth 1 - 2 # node 5 distance depth 0 - 5 # node 5 distance depth 1 - 1 # # After fix # node 3 distance depth 0 - 3 # node 3 distance depth 1 - 1 # node 4 distance depth 0 - 4 # node 4 distance depth 1 - 2 # node 5 distance depth 0 - 5 # node 5 distance depth 1 - 1 # # Without the fix, the nearest numa node to the pmem device (NUMA node 3) # will be picked as 4. After the fix, we get the correct numa node which # is 5. # # Fixes: da1115fdbd6e ("powerpc/nvdimm: Pick nearby online node if the device node is not online") # Signed-off-by: Aneesh Kumar K.V # Signed-off-by: Michael Ellerman # Link: https://msgid.link/20230404041433.1781804-1-aneesh.kumar@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 b277fc793daf258877b4c0744b52f69d6e6ba22e # < make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc85xx_defconfig # 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 40 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4477:warning: override: reassigning to symbol PPC_E500MC .config:4478:warning: override: reassigning to symbol VIRTUALIZATION # make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-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:22:49: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] 22 | #define IS_ERR_VALUE(x) unlikely((unsigned long)(void *)(x) >= (unsigned long)-MAX_ERRNO) | ^ /kisskb/src/include/linux/compiler.h:78:45: note: in definition of macro 'unlikely' 78 | # define unlikely(x) __builtin_expect(!!(x), 0) | ^ /kisskb/src/drivers/net/ethernet/freescale/fs_enet/mac-scc.c:139:13: note: in expansion of macro 'IS_ERR_VALUE' 139 | if (IS_ERR_VALUE(fep->ring_mem_addr)) | ^~~~~~~~~~~~ /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8541cds.dts:341.15-350.5: Warning (pci_device_reg): /pci@e0008000/i8259@19000: PCI unit address format error, expected "12,0" /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8541cds.dts:330.3-21: Warning (pci_device_bus_num): /pci@e0008000/i8259@19000:bus-range: PCI bus number 1 out of range, expected (0 - 0) /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8555cds.dts:341.15-350.5: Warning (pci_device_reg): /pci@e0008000/i8259@19000: PCI unit address format error, expected "12,0" /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8555cds.dts:330.3-21: Warning (pci_device_bus_num): /pci@e0008000/i8259@19000:bus-range: PCI bus number 1 out of range, expected (0 - 0) Completed OK # rm -rf /kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc12 # Build took: 0:02:03.594835
