Hmm, couldn't get one which needs smm to be called on cpu 0. OTOH I've done various tests and added a printk() in raise_smm() and i8k_smm_func() issuing the cpu number it was called on. > Some notebooks which needs smm call to issued from cpu 0 can be found in > git commit messages of i8k, dell-laptop or dcdbas kernel drivers. > >> What would you do for testing?

I have a Dell Inspiron 8100 laptop (or I8K) with a NVidia Geforce2 Go (or NV11) with an embedded CH7007A chip, and am seeing the following after getting ch7006 kernel driver/module loaded: # dmesg |grep ch7006 -i --- Snip --- [ 21.191147] nouveau [ I2C][0000:01:00.0] detected TV encoder: ch7006 [ 21.404731] ch7006 1-0075: ch700...

...I'd probably turn these all into: if (cpu >= 0 && ret < 0) { pr_warn("Failed to pin VCPU %d to physical CPU %d: %d", smp_processor_id(), cpu, ret); disable_pinning = true; } And look at getting the user of this API to print a more useful error. "i8k: unable to call SMM BIOS on physical CPU %d: %d" Or whatever. David
