Question wtf.. is it a i386 or x86_64


Hi Folks,

I am running crazy about the kind of processor I have here.

Here is what I got - short output:

Code:
# lspci -v

00:00.0 Host bridge: Advanced Micro Devices [AMD] RS880 Host Bridge
	Subsystem: Acer Incorporated [ALI] Device 036e
	Flags: bus master, 66MHz, medium devsel, latency 0

00:04.0 PCI bridge: Advanced Micro Devices [AMD] RS780 PCI to PCI bridge (PCIE port 0) (prog-if 00 [Normal decode])
	Capabilities: [a0] MSI: Enable+ Count=1/1 Maskable- 64bit-

00:13.0 USB Controller: ATI Technologies Inc SB7x0/SB8x0/SB9x0 USB OHCI0 Controller (prog-if 10 [OHCI])
	Subsystem: Acer Incorporated [ALI] Device 036e
	Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 18
	Memory at 92305000 (32-bit, non-prefetchable) [size=4K]
	Kernel driver in use: ohci_hcd
When I purchased this laptop, the sales person told me to have on it a 32bits AMD processor. Recently I installed a FC16 64bits and it did not complained about, and it is running smoothly. But on the other hand the ATI shows 32-bit.

So, if the it is a 64bits, why the sales person told it to be a 32bits. On the other hand, if it is a 32bits, how did it accepted installing the 64bits FC16?

All comments are highly appreciated and welcome!

Hi!

Try to look at the output of lshw, that's where the dataz of the CPU is found...

Dare I think it possible to have a 64-bit CPU with some 32-bit stuff around it?

Following this interesiting thread, thanks!

Thor

Run:
Code:
cat /proc/cpuinfo
If you see lm in the flags, it's 64-bit.

Question

Hi BrianL,

I see one kind of lm in the flags: lahf_lm .

Here is what I got as output:

Code:
[root@gold ~]# cat /proc/cpuinfo
processor	: 0
vendor_id	: AuthenticAMD
cpu family	: 16
model		: 6
model name	: AMD V120 Processor
stepping	: 3
cpu MHz		: 800.000
cache size	: 512 KB
fpu		: yes
fpu_exception	: yes
cpuid level	: 5
wp		: yes
flags		: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm 3dnowext 3dnow constant_tsc up rep_good nopl nonstop_tsc extd_apicid pni monitor cx16 popcnt lahf_lm svm extapic cr8_legacy abm sse4a 3dnowprefetch osvw ibs skinit wdt nodeid_msr npt lbrv svm_lock nrip_save
bogomips	: 4388.83
TLB size	: 1024 4K pages
clflush size	: 64
cache_alignment	: 64
address sizes	: 48 bits physical, 48 bits virtual
power management: ts ttp tm stc 100mhzsteps hwpstate
So... it is a x86_64. Right? It is a little confusing indeed. If a sales person come to you and try to sell you a i386 telling it to be a x86_64, would be a little bit snick, but on the way around really makes no sense at all.

Thanks for the feedback!

You've got lm in there, too. So you can run the x86_64 versions of any distro.
