Re: Why are core_id and CurrentCpusFormat() differences?

[Nick Sanders]

CPU 0(0x80) is reported here:

https://github.com/stressapptest/stressapptest/blob/c8ce5af2c2ac12377d1c229f8be73410acdd00ff/src/worker.cc#L610

the intent is to print the CPU the thread is running on, and the cpuset it's allowed to run on. In your case, it may be that sched_getcpu isn't returning the correct result, or the API has changed since stressapptest was written.

The "bus address" is the physical address as viewed by the CPU, via https://www.kernel.org/doc/Documentation/vm/pagemap.txt, although there are a number of things that could be considered a "physical address" depending on the system.

Dear sir , 

            This is my error log .  

            I want to know why CPU 0 has 0x80 , 0x10 , 0x40  , 3 types .

            I know the core_id use gnu sched_getcpu() but why CPU 0 isn't equal 0x1 ??

            And how do i get physical address of errors  , it seems to be bus address?(uint64 paddr; // This is the bus address, if available.)

Many thanks ,

Victor
