CPUID ALL in ASM

[michaeled314]

Code: Select all

CPUName.s = Space(12)
pCPUName.l = @CPUName
FPU.l
VME.l


!XOR eax,eax
!CPUID
MOV eax,pCPUName
MOV [eax],ebx
MOV [eax+4],edx
MOV [eax+8],ecx
MOV CPUName,eax

MOV eax,1
!CPUID

BT eax,0
ADC FPU,0
BT eax,1
ADC VME,0

Nice work.

Thanks for passing it on.

Well I tried to make it work but somethings wrong with it:

Code: Select all

CPUName.s = Space(12)
pCPUName.l = @CPUName
FPU.l
VME.l

!XOR eax,eax
!CPUID

!MOV eax,[v_pCPUName]
!MOV [eax],ebx
!MOV [eax+4],edx
!MOV [eax+8],ecx
!MOV [v_CPUName],eax

!MOV eax,1
!CPUID

!BT eax,0
!ADC [v_FPU],0
!BT eax,1
!ADC [v_VME],0

Debug CPUName
Debug FPU
Debug VME

Debug GetCPUName()

I cant remember where the hell I came accross this bit of code.... maybe purearea? Either way, does the job.

[superadnim]

yep thanks, although it looks quite messy to be frank with you

[LuCiFeR[SD]]

LOL, yeah, it is a little messy. Lets see what can be done about that

[Thunder93]

Nice...!

Though using LuCiFeR[SD] code, the CPU Specification retrieved and not the actual CPU name.

[breeze4me]

LuCiFeR[SD]'s code will be OK on AMD machines, not Intel.

yes, the actual x86 reference manual hosts a whopping 29 pages dedicated to this instruction only... I got lost at the second one
