This leads to error reported cacheinfo: Unable to detect cache hierarchy for CPU 0 Way to fix this provided in commit fac51482577d ("drivers: base: cacheinfo: fix x86 with CONFIG_OF enabled") Utilize same mechanism to report that cacheinfo set by architecture specific function Signed-off-by: Vladimir Kondratiev Signed-off-by: Paul Burton Cc: Ralf Baechle Cc: James Hogan Cc: linux-mips@vger.kernel.org Cc: linux-kernel@vger.kernel.org Signed-off-by: Sasha Levin --- arch/mips/kernel/cacheinfo.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/mips/kernel/cacheinfo.c b/arch/mips/kernel/cacheinfo.c index 97d5239ca47ba..428ef21892039 100644 --- a/arch/mips/kernel/cacheinfo.c +++ b/arch/mips/kernel/cacheinfo.c @@ -80,6 +80,8 @@ static int __populate_cache_leaves(unsigned int cpu) if (c->tcache.waysize) populate_cache(tcache, this_leaf, 3, CACHE_TYPE_UNIFIED); + this_cpu_ci->cpu_map_populated = true; + return 0; }
