Hi, Sudeep,
Please see this call-graph:
static int detect_cache_attributes(unsigned int cpu)
ret = populate_cache_leaves(cpu);
ret = cache_shared_cpu_map_setup(cpu); -->
cache_setup_of_node() --> cache_of_set_props() -->
cache_size()/cache_nr_sets
Hi, Sudeep,
Please see this call-graph:
static int detect_cache_attributes(unsigned int cpu)
ret = populate_cache_leaves(cpu);
ret = cache_shared_cpu_map_setup(cpu); -->
cache_setup_of_node() --> cache_of_set_props() -->
cache_size()/cache_nr_sets

Commit 448a5a552f336bd7b847b1951 ("drivers: base: cacheinfo: use OF
property_read_u32 instead of get_property,read_number") makes cache
size and number_of_sets be 0 if DT doesn't provide there values. I
think this is unreasonable so make them keep the old values, which is
the same as old kernels.
