Since the information exposed by this # attribute cannot be cached it is better to ward off access to this # attribute from users who don't need to access to these performance # statistics. # # Hence update the access mode of 'perf_stats' attribute to be only # readable by root users. # # Fixes: 2d02bf835e57 ("powerpc/papr_scm: Fetch nvdimm performance stats from PHYP") # Reported-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> # Signed-off-by: Vaibhav Jain <vaibhav@linux.ibm.com> # Reviewed-by: Ira Weiny <ira.weiny@intel.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20200907110540.21349-1-vaibhav@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 0460534b532e5518c657c7d6492b9337d975eaa3 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-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 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4125:warning: override: reassigning to symbol PPC_E500MC .config:4126:warning: override: reassigning to symbol VIRTUALIZATION # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/include/linux/kernel.h:11, from /kisskb/src/include/linux/list.h:9, 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:78:42: 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:139:6: note: in expansion of macro 'IS_ERR_VALUE' 139 \| if (IS_ERR_VALUE(fep->ring_mem_addr)) \| ^~~~~~~~~~~~ cc1: fatal error: opening output file arch/powerpc/boot/dts/fsl/.mpc8540ads.dtb.dts.tmp: No such file or directory compilation terminated. make[2]: [scripts/Makefile.lib:326: arch/powerpc/boot/dts/fsl/mpc8540ads.dtb] Error 1 make[2]: * Waiting for unfinished jobs.... make[1]: * [arch/powerpc/Makefile:295: zImage] Error 2 make[1]: * Waiting for unfinished jobs.... make: *** [Makefile:185: __sub-make] Error 2 Command 'make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-9.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc9 # Build took: 0:02:23.150690
