It must have a buggy implementation of its cpuid emulation, then.
Is it possible for you to insert this:
@@ -848,6 +858,11 @@ func (c *CPUInfo) cacheSize() {
if typ == 0 {
return
}
+ fmt.Printf("EAX: 0x%08x, EBX: 0x%08x, ECX: 0x%08x; ", eax, ebx, ecx)
+ fmt.Println("type", typ, "size:", size)
+ if i > 100 {
+ return
+ }
switch level {
case 1:
I need a secondary break condition.
The docs specify that EAX low 4==0 bits indicates that there are no more (page 33).

ok, this is buggy, unless you have endless level 1 data cache :)
Seems like it just ignores ECX value given, which should return different cache levels.

Great, thanks. Yes, I don't think I have an infinite cache unfortunately :)

Thanks for the help.
You can try the cpuid of the latest release: https://github.com/klauspost/cpuid/releases/tag/v2.0.14 - should catch your case.
I will upstream if you can confirm it works.
