x86/debug: Dump family, model, stepping of the boot CPU When acting on a user bug report, we find ourselves constantly asking for /proc/cpuinfo in order to know the exact family, model, stepping of the CPU in question. Instead of having to ask this, add this to dmesg so that it is visible and no ambiguities can ensue from looking at the official name string of the CPU coming from CPUID and trying to map it to f/m/s. Output then looks like this: [ 0.146041] smpboot: CPU0: AMD FX(tm)-8100 Eight-Core Processor (fam: 15, model: 01, stepping: 02) Signed-off-by: Borislav Petkov <[email protected]> Cc: Andreas Herrmann <[email protected]> Link: http://lkml.kernel.org/r/[email protected] [ tweaked it minimally to add commas. ] Signed-off-by: Ingo Molnar <[email protected]> --- arch/x86/kernel/cpu/common.c | 8 +++++--- 1 files changed, 5 insertions(+), 3 deletions(-) diff --git a/arch/x86/kernel/cpu/common.c b/arch/x86/kernel/cpu/common.c index a5fbc3c..1cc48ff 100644 --- a/arch/x86/kernel/cpu/common.c +++ b/arch/x86/kernel/cpu/common.c @@ -1023,14 +1023,16 @@ void __cpuinit print_cpu_info(struct cpuinfo_x86 *c) printk(KERN_CONT "%s ", vendor); if (c->x86_model_id[0]) - printk(KERN_CONT "%s", c->x86_model_id); + printk(KERN_CONT "%s", strim(c->x86_model_id)); else printk(KERN_CONT "%d86", c->x86); + printk(KERN_CONT " (fam: %02x, model: %02x", c->x86, c->x86_model); + if (c->x86_mask || c->cpuid_level >= 0) - printk(KERN_CONT " stepping %02x\n", c->x86_mask); + printk(KERN_CONT ", stepping: %02x)\n", c->x86_mask); else - printk(KERN_CONT "\n"); + printk(KERN_CONT ")\n"); print_cpu_msr(c); } -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
