However this can cause CPU to be made # part of the wrong node, (most likely to be node 0). This is because # VPHN is not enabled on KVM guests. # # With 2ea6263 ("powerpc/topology: Get topology for shared processors at # boot"), associativity is used to set to the wrong node. Hence KVM # guest topology is broken. # # For example : A 4 node KVM guest before would have reported. # # [root@localhost ~]# numactl -H # available: 4 nodes (0-3) # node 0 cpus: 0 1 2 3 # node 0 size: 1746 MB # node 0 free: 1604 MB # node 1 cpus: 4 5 6 7 # node 1 size: 2044 MB # node 1 free: 1765 MB # node 2 cpus: 8 9 10 11 # node 2 size: 2044 MB # node 2 free: 1837 MB # node 3 cpus: 12 13 14 15 # node 3 size: 2044 MB # node 3 free: 1903 MB # node distances: # node 0 1 2 3 # 0: 10 40 40 40 # 1: 40 10 40 40 # 2: 40 40 10 40 # 3: 40 40 40 10 # # Would now report: # # [root@localhost ~]# numactl -H # available: 4 nodes (0-3) # node 0 cpus: 0 2 3 4 5 6 7 8 9 10 11 12 13 14 15 # node 0 size: 1746 MB # node 0 free: 1244 MB # node 1 cpus: # node 1 size: 2044 MB # node 1 free: 2032 MB # node 2 cpus: 1 # node 2 size: 2044 MB # node 2 free: 2028 MB # node 3 cpus: # node 3 size: 2044 MB # node 3 free: 2032 MB # node distances: # node 0 1 2 3 # 0: 10 40 40 40 # 1: 40 10 40 40 # 2: 40 40 10 40 # 3: 40 40 40 10 # # Fix this by skipping associativity lookup if the VPHN hcall failed. # # Fixes: 2ea626306810 ("powerpc/topology: Get topology for shared processors at boot") # Signed-off-by: Srikar Dronamraju <srikar@linux.vnet.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 2483ef056f6e42f61cd266452e2841165dfe1b5c # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-randconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig KCONFIG_SEED=0xE1EDCEB8 # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_LD_HEAD_STUB_CATCH=y # Added to kconfig # yes \n | make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-randconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_powerpc-randconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/scripts/unifdef.c: In function 'Mpass': /kisskb/src/scripts/unifdef.c:453:28: warning: 'strncpy' output truncated before terminating nul copying 4 bytes from a string of the same length [-Wstringop-truncation] static void Mpass (void) { strncpy(keyword, "if ", 4); Pelif(); } ^~~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/powerpc/kernel/eeh.c:1752:12: warning: 'proc_eeh_show' defined but not used [-Wunused-function] static int proc_eeh_show(struct seq_file *m, void *v) ^ /kisskb/src/drivers/gpu/drm/amd/amdgpu/soc15.c: In function 'soc15_set_ip_blocks': /kisskb/src/drivers/gpu/drm/amd/amdgpu/soc15.c:532:3: warning: #warning "Enable CONFIG_DRM_AMD_DC for display support on SOC15."
