From 7db5e9e9e5e6c10d7d26f8df7f8fd8841cb15ee7 Mon Sep 17 00:00:00 2001 From: Huang Pei Date: Thu, 25 Nov 2021 18:59:49 +0800 Subject: MIPS: loongson64: fix FTLB configuration It turns out that 'decode_configs' -> 'set_ftlb_enable' is called under c->cputype unset, which leaves FTLB disabled on BOTH 3A2000 and 3A3000 Fix it by calling "decode_configs" after c->cputype is initialized Fixes: da1bd29742b1 ("MIPS: Loongson64: Probe CPU features via CPUCFG") Signed-off-by: Huang Pei Signed-off-by: Thomas Bogendoerfer --- arch/mips/kernel/cpu-probe.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'arch/mips') diff --git a/arch/mips/kernel/cpu-probe.c b/arch/mips/kernel/cpu-probe.c index ac0e2cfc6d57..24a529c6c4be 100644 --- a/arch/mips/kernel/cpu-probe.c +++ b/arch/mips/kernel/cpu-probe.c @@ -1734,8 +1734,6 @@ static inline void decode_cpucfg(struct cpuinfo_mips *c) static inline void cpu_probe_loongson(struct cpuinfo_mips *c, unsigned int cpu) { - decode_configs(c); - /* All Loongson processors covered here define ExcCode 16 as GSExc. */ c->options |= MIPS_CPU_GSEXCEX; @@ -1796,6 +1794,8 @@ static inline void cpu_probe_loongson(struct cpuinfo_mips *c, unsigned int cpu) panic("Unknown Loongson Processor ID!"); break; } + + decode_configs(c); } #else static inline void cpu_probe_loongson(struct cpuinfo_mips *c, unsigned int cpu) { } -- cgit
