Data needed for AMD threadripper 16 core 2950x CPU
by h2-1 from LinuxQuestions.org on (#6H9XG)
Someone posted an issue about incorrect core counts for inxi CPU with AMD Threadripper 2950x 16 core CPU. But then decided not to provide the required data to debug the issue. Rather than wait, figured I'd see if anyone here can provide it.
This is one that has 2 dies, but to correct the issue I need these two files:
Code:for i in $(find /sys/devices/system/cpu/ -type f); do echo ${i}::$(cat $i 2>/dev/null);done | sort > cpu-data-sys.txt; cp -f /proc/cpuinfo cpu-data-cpuinfo.txtThat crudely produces the data in a format inxi can digest to emulate the issue. Just upload those somewhere and provide the links to the two.
Note it has to be a 16 core or greater Zen+, the Zen 2 3990x does not appear to have this issue, I've got a set of that data from a 64 core version and tested it, and it's fine. AMD clearly did a subtle change to how they report the die, because the 3990x shows only 1 die, when it should have 4, but keeping up with how these are actually made is hard.
If anyone has this CPU and can provide this data, much appreciated.
You can see if your cpu has the issue by testing with current inxi: inxi -Cxxx
and if it shows half the actual CPU core count, it does. Note it will show the proper speed per cores, 2x the actual physical cores, but will say it's 1/2 the actual physical cores, with 2 dies, or more of it's more than 16 cores.
This is corner case, but if you should happen to have this exact CPU, appreciate the data.
This is a scenario that may have slipped by in the initial big CPU refactor we did here a while back.
