Well, in my case that returns 4 stanza's of this:
processor : 3
vendor_id : AuthenticAMD
cpu family : 16
model : 2
model name : AMD Phenom(tm) 9550 Quad-Core Processor
stepping : 3
cpu MHz : 2210.462
cache size : 512 KB
physical id : 0
siblings : 4
core id : 3
cpu cores : 4
apicid : 3
initial apicid : 3
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 5
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov
pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb
rdtscp lm 3dnowext 3dnow constant_tsc nonstop_tsc extd_apicid pni monitor
cx16 popcnt lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse
3dnowprefetch osvw ibs
bogomips : 4420.70
clflush size : 64
cache_alignment : 64
address sizes : 48 bits physical, 48 bits virtual
power management: ts ttp tm stc 100mhzsteps hwpstate
And I don't see anything there that looks like a 'patch level'.
The ucode obviously can, which is what counts in this game of horseshoes.
Perhaps something in that very long 'flags' string?
Thanks Borislav.
Cheers, Gene
