Ubuntu 12.04 3.2 Kernel showing incorrect "cache size" in cpuinfo?
- by Tom G
2x Xeon E5620 .
16 Cores altogether.
/proc/cpuinfo shows cache is only @ 4096kb
According to intel this should have 12MB of "smart cache".
Doing searched for E5620 and CPUinfo shows the correct number:
cache size : 12288 KB
However mine shows this:
processor : 15
v endor_id : GenuineIntel
cpu family : 6
model : 44
model name : Intel(R) Xeon(R) CPU E5620 @ 2.40GHz
stepping : 2
microcode : 0x1
cpu MHz : 2400.104
cache size : 4096 KB
fpu : yes
fpu_exception : yes
cpuid level : 11
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush mmx
bogomips : 4800.20
clflush size : 64
cache_alignment : 64
address sizes : 40 bits physical, 48 bits virtual
Any idea on why it shows like it's missing 8MB in CPU cache?
