Unlike drivers/base/cacheinfo, powerpc cacheinfo code is not exposing shared_cpu_list under /sys/devices/system/cpu/cpu<n>/cache/index<m> Add shared_cpu_list to per cpu per index directory to maintain parity with x86. Some scripts (example: mmtests https://github.com/gormanm/mmtests) seem to be looking for shared_cpu_list instead of shared_cpu_map. Before this patch: # ls /sys/devices/system/cpu0/cache/index1 coherency_line_size number_of_sets size ways_of_associativity level shared_cpu_map type # cat /sys/devices/system/cpu0/cache/index1/shared_cpu_map 00ff # After this patch: # ls /sys/devices/system/cpu0/cache/index1 coherency_line_size number_of_sets shared_cpu_map type level shared_cpu_list size ways_of_associativity # cat /sys/devices/system/cpu0/cache/index1/shared_cpu_map 00ff # cat /sys/devices/system/cpu0/cache/index1/shared_cpu_list 0-7 # Signed-off-by: Srikar Dronamraju <srikar@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/20200629103703.4538-4-srikar@linux.vnet.ibm.com |
