Shenoy <ego@linux.vnet.ibm.com> # Date: Thu Dec 10 16:08:59 2020 +0530 # # powerpc/cacheinfo: Print correct cache-sibling map/list for L2 cache # # On POWER platforms where only some groups of threads within a core # share the L2-cache (indicated by the ibm,thread-groups device-tree # property), we currently print the incorrect shared_cpu_map/list for # L2-cache in the sysfs. # # This patch reports the correct shared_cpu_map/list on such platforms. # # Example: # On a platform with "ibm,thread-groups" set to # 00000001 00000002 00000004 00000000 # 00000002 00000004 00000006 00000001 # 00000003 00000005 00000007 00000002 # 00000002 00000004 00000000 00000002 # 00000004 00000006 00000001 00000003 # 00000005 00000007 # # This indicates that threads {0,2,4,6} in the core share the L2-cache # and threads {1,3,5,7} in the core share the L2 cache. # # However, without the patch, the shared_cpu_map/list for L2 for CPUs 0, # 1 is reported in the sysfs as follows: # # /sys/devices/system/cpu/cpu0/cache/index2/shared_cpu_list:0-7 # /sys/devices/system/cpu/cpu0/cache/index2/shared_cpu_map:000000,000000ff # # /sys/devices/system/cpu/cpu1/cache/index2/shared_cpu_list:0-7 # /sys/devices/system/cpu/cpu1/cache/index2/shared_cpu_map:000000,000000ff # # With the patch, the shared_cpu_map/list for L2 cache for CPUs 0, 1 is # correctly reported as follows: # # /sys/devices/system/cpu/cpu0/cache/index2/shared_cpu_list:0,2,4,6 # /sys/devices/system/cpu/cpu0/cache/index2/shared_cpu_map:000000,00000055 # # /sys/devices/system/cpu/cpu1/cache/index2/shared_cpu_list:1,3,5,7 # /sys/devices/system/cpu/cpu1/cache/index2/shared_cpu_map:000000,000000aa # # This patch also defines cpu_l2_cache_mask() for !CONFIG_SMP case. # # Signed-off-by: Gautham R.
