Boost states dont works with Bulldozer #21

The enable disable boost states dont works with Bulldozer.
I need to use the program PSCheck from AMD to handle the boost states.

when i said Bulldozer, i wanted to said the 8150 processor 8-core Bulldozer 
family processor.

Thx in advance

Thanks for the report.

Unfortunately, I don't have an FX CPU I can test with so I'll need a bit of your
help.

Can you tell me what command lines were you using and what results you've got?
Also, which version of TPC are you using?

Boost manipulation works fine on Opteron 15h CPUs here so I think we can get it
working on the FX series as well.

ok, the bulldozer processor comes with two bosst states. By default the first 
is switched automatically when a core reach the pstate 0. Then i have tried to 
enable an disable boost states without success. Also i wanted to see a way to 
change the boost state 1 by the 0.

 - Boost state 0 = 4200 Mhz
 - Boost state 1 = 3900 Mhz (used by default by the cpu if we use an adaptive mode)

thx in advance

Can you show me exact tpc command lines you used to enable/disable p-states?

Also, can you elaborate a bit on this comment, please?
"Also i wanted to see a way to change the boost state 1 by the 0."
I'm not sure what you have in mind...

Thank you :)

ok, i have used the follow commands to try to enable and disable the two boots 
states that have the bulldozer.

turionpowercontrol -boostenable
turionpowercontrol -boostdisable

The bulldozer has two boost states defined on it by default:

- b0 = 4200 Mhz
- b1 = 3900 Mhz

If i set an adaptive power scheme, i can see how the processor switches 
automatically to boost state 1 when a core pstate reach the pstate 0, that is 
3600 Mhz.

So i expected to be able to disable the boost states, and to change to the 
boost state 0. In fact i did it with the use of AMD program PSCheck. But at the 
moment TPC, for some reasson and with these commands, doesnt works.

greetings

My experience shows that forcing HW P-state 0 (SW P-state Pb0) does not work on
Family 15h CPUs (though I only played with server CPUs).

Can you tell me exact sequence of commands (step-by-step) in the PSCheck utility
that works with your 8150 chip? (with few screenshots)

Also, after you perform the procedure with PSCheck, can you run 
TurionPowerControl.r184 -CM for 60 seconds and then take a screenshot of that 
as well?
