>Description:
Intel Turbo Boost Technology not working, re-released Intel Hyper-Threading Technology demonstrates performance drop.

sysctl -a output attached

Not possible to see CPU P0-state/C3-state usage, required to enable Turbo Boost Technology, see http://www.intel.com/technology/turboboost/
>How-To-Repeat:
1. Disabled both Turbo Boost and Hyper-Threading.
2. take some benchmarking (both single threaded and 8-16 threaded)
3. Enabled Turbo Boost (only)
4. take some benchmarking - same results (1-2% difference)
5. Enabled both Turbo Boost and Hyper-Threading.
6. take some benchmarking - 10-15% performance drop
>Fix:
Not use Hyper-Threading, but still no Turbo Boost benefits

State-Changed-From-To: closed->open  
State-Changed-By: brucec 
State-Changed-When: Sun Sep 12 10:35:23 UTC 2010 
State-Changed-Why:  
This does appear to be a bug, but only in the ACPI code: Hyperthreading  
isn't guaranteed to give a performance increase for every workload, and  
TurboBoost is only seen once lower Cx states are enabled. 


Responsible-Changed-From-To: brucec->freebsd-acpi  
Responsible-Changed-By: brucec 
Responsible-Changed-When: Sun Sep 12 10:35:23 UTC 2010 
Responsible-Changed-Why:  
Over to the acpi list. 
This appears to be a problem with ACPI on the machine, because C2 and C3  
states should probably be available.

 First of all, the PR was created improperly - sysctl -a output is in "Fix"
 section for some reason.  Please don't do that in the future.
 
 Second, it's impossible to tell if "C2 and C3 states should probably be
 available" unless we see acpidump -dt output and dmesg with ACPI debugging
 enabled (ACPI_PROCESSOR x ACPI_DB_INFO):
 http://www.freebsd.org/doc/handbook/acpi-debug.html
 
 P.S.
 That is, generally we expect to see C2 and C3 levels, but not universally.
 BIOS or BIOS configuration, motherboard peculiarities and OS supported features
 are among the thing that affect C2+ availability.

 So you do have the levels reported in cx_supported?
 This is not what you attached to the PR.  And this is not what I tried to debug.
 I am not sure what changed in your environment, but you should have said that you
 have the those levels reported and not wasted my time on this.
 
 Please ask the above on questions@.

 Great!  That was a wise decision on your part.
 But you should have told us/me that (e.g. followed up to your own PR).
 OK, now you can enable use of lower Cx states via hw.acpi.cpu.cx_lowest sysctl and
 the PR can be closed.

 And now there is this code in acpi_cpu.c:
 
     /* Find the lowest state that has small enough latency. */
     cx_next_idx = 0;
     for (i = sc->cpu_cx_lowest; i >= 0; i--) {
         if (sc->cpu_cx_states[i].trans_lat * 3 <= sc->cpu_prev_sleep) {
             cx_next_idx = i;
             break;
         }
     }
 
 205 * 3 and 245 * 3 are both greater than 500, so this is the reason why they are
 never entered.
 
 Perhaps Alexander can give some advice here.

 The only way to enter C-states with so high latency is significantly
 increase CPUs' continuous sleep time. Sleep time of 500ms there is
 artificial and calculated as 1000000/(2*hz). 8.1 was unable yet to
 measure real sleep time in C1. But 2*hz is quite realistic estimation
 for idle system.
 
 Recently I have committed to 9-CURRENT large set of patches, making idle
 CPUs to not wake up on timer interrupts when it is not needed. It allows
 idle CPUs sleep up to as much as 100000us, making any C-states available
 now effectively usable. I can acknowledge that TurboBoost on my Core i7
 870 gives about 10% benefit when only one physical core is used:
 http://docs.freebsd.org/cgi/mid.cgi?4C959830.3060808
 
 I have requests and wish to merge these changes into 8-STABLE, but most
 likely it won't happen in nearest few months, as code is very new and
 requires more testing.
 
 Until that time I recommend you to follow this guide:
 http://wiki.freebsd.org/TuningPowerConsumption
 It was actually oriented on laptops, but effective usage of C2/C3 states
  was one of it's goals. Also on my Core i7 870 LAPIC dies in C2/C3
 states, so consider migration to i8254 timer, as also described in this
 guide.

 Ok, I am able to activate C3 state after loader.conf tweaks. According 
 to http://www.intel.com/technology/turboboost/
 
 Intel Turbo Boost Technology is activated when the Operating System (OS) 
 requests the highest processor performance state (P0).
 
 I have no clue about P0 state activation on FreeBSD.

 P0 is just a highest available CPU frequency. If you are not using
 powerd - it should be set all the time. If you are using powerd - it
 will set it in part of second after load appear.

 This CPU has only 266MHz TurboBoost speedup. And some part of it
 (probably half) could be enabled all the time. This benefit still could
 be overweighted by C-states latencies penalty. It could be interesting
 to test some other workloads, like compilation with different number of
 threads.

 Intel writes that BIOS may report additional P-state with 1MHz
 difference, to allow OS to control TurboBoost. It's just cpufreq
 subsystem behavior/limitation to drop very close frequencies. Actually I
 am not sure how this additional P-state could be used, except for testing.

 Disk performance fix is reasonable. Some recent improvements in
 9-CURRENT should improve it even more. What's about ubench - try some
 different load.

 Actually tested 8.1-RELEASE with both TurboBoost options in BIOS:
 
 TurboBoost OFF
 Ubench Single CPU:   451935 (0.40s)
 Ubench Single CPU:   450927 (0.40s)
 Ubench Single CPU:   450486 (0.40s)
 
 TurboBoost ON
 Ubench Single CPU:   450890 (0.40s)
 Ubench Single CPU:   450890 (0.40s)
 Ubench Single CPU:   449926 (0.40s)
 
 C-states latencies penalty is reasonable idea. But looks like P0-state 
 not activated at all.
 What about too high %% for C3 state during heavy load:
 dev.cpu.0.cx_usage: 0.17% 0.06% 99.75% last 7560us

 Can you suggest other CPU only benchmark?
 
 make -j 16 buildworld
 can't load all cores, can't see less than 11% idle

 Try to kill powerd and manually set highest CPU frequency. 0.40s test
 time looks a bit suspicious, as powerd may just not react in time to set
 P0 state.

 It's not really strange. These numbers count number of enters into each
 state. So when CPU is completely bust - they won't be updated. Main case
 when C1 state should be actively used/counted is loads with high
 interrupt rate or heavy context switching, such as disk I/O or network load.

 I think it's not the main goal to completely load all CPUs. But this
 test is realistic and has really usable result.

 powerd does not enabled. Where/how set highest CPU frequency?

 dev.cpu.0.freq: 3334

 1000/20000 800/16000 600/12000 400/8000 200/4000
 
 So its already max freq.

 Is it possible to stick running threads to same CPU core for longer time 
 to avoid C-states latencies penalty?

State-Changed-Why:  
The issue as described in this PR is not present in stable/8. 
ACPI in stable/7 is not going to be updated. 
In stable/8 C3 is reported but is never used in default 
configuration, because processor never sleeps long enough 
to C3 state with that long enter/exit delay. 
The reporter is tuning his system for optimal performance.

 Its static assignment, requires scheduling all tasks by hand.
 
 cpuset -l 7 ubench -cs
 Ubench Single CPU:   453051 (0.40s)
 less than 1% boost.
