Detecting Haswell #71

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
Step 1. What steps will reproduce the problem?

Running i7z gives this info:
i7z DEBUG: i7z version: svn-r77-(20-Nov-2011)
i7z DEBUG: Found Intel Processor
i7z DEBUG:    Stepping 3
i7z DEBUG:    Model c
i7z DEBUG:    Family 6
i7z DEBUG:    Processor Type 0
i7z DEBUG:    Extended Model 3
i7z DEBUG: msr = Model Specific Register
i7z DEBUG: detected a newer model of ivy bridge processor
i7z DEBUG: my coder doesn't know about it, can you send the following info to 
him?
i7z DEBUG: model c, extended model 3, proc_family 6
i7z DEBUG: msr device files exist /dev/cpu/*/msr
i7z DEBUG: You have write permissions to msr device files
(...)
i7z DEBUG: Single Socket Detected
i7z DEBUG: In i7z Single_Socket()
i7z DEBUG: guessing Nehalem

Step 2. What version of the product are you using (the download version or
the svn
version and which one)?
One from Arch Linux repository, it says svn-r77-(20-Nov-2011)

Step 3. If this is an enhancement or suggestion, skip this step (except if
its related to a particular OS or architecture). On what operating system?
BTW is it a 32-bit or a 64-bit OS/Kernel?

Step 4. Do provide information if bug/enhancement is related to a
particular OS/Processor. Please provide any additional information below
(helpful will be platform
information like number and types of cpus, motherboard and a copy of
/proc/cpuinfo)
It's Core i7 Haswell, specifically 4770, on B85M-G43 motherboard

Step 5. If the program crashes. Can you also paste the
output of ls -lt /dev/cpu/*/msr?

Step 6. If the program crashed OR if this is for a new i7 chip. Can you
also run the following commands? They read various registers
and if those registers cannot be read the tool fails ungracefully. You will
have to sudo
each commmand and probably also do sudo modprobe msr (before running the
programs)

rdmsr 0x19c
rdmsr 0x1a2
rdmsr 0x38d
rdmsr 778
rdmsr 779
rdmsr 1020
rdmsr 1021
