My Kernel have all features from my Hardware?

Candelabrus · 05-01-2015, 06:46 PM

Hi guys,

I always had doubts whether the config I use to compile my kernel is taking advantage of all my hardware. So I created this topic to see if you help me.

My setup:
i5 4670k @ 4.5GHz
Asus Z97-Pro
2x4GB Corsair DDR3-2100mhz @ 2.400mhz
Nvidia Gigabyte G1 970GTX
Logitech G700 Wireless

Here my config kernel:
http://pastebin.com/wS5ca3yE

And here download config
https://www.dropbox.com/s/3iqjp82y9r862r4/.config?dl=0

So with this data you can help me improve my kernel configuration to better enjoy my hardware?

Set the processor type to 'Core 2/Newer Xeon'.

Unless this is a media server or low latency system, I recommend 'Voluntary Kernel Preemption'.

For better power saving and heat management, I recommend the 'ondemand' cpu frequency governor.

You are probably going to want the proprietary nvidia driver for that graphics card for maximum performance.

This CPU has turbo boost, you can check it with:

Code:

cat /sys/devices/system/cpu/cpufreq/boost

and turn it on with:

Code:

echo 1 > /sys/devices/system/cpu/cpufreq/boost

Some possibly useful info:
http://docs.slackware.com/howtos:sla...git_repository
http://docs.slackware.com/howtos:har...quency_scaling

P.S. You may also want to check the BIOS settings and if you want even more performance there may be an XMP profile for the RAM. Enable it and you will get faster RAM. Sometimes you have to plug in the frequencies and CL timings yourself, they should be written on the RAM sticks or the box they came in, but only put correct values or your system will not boot.

Here i do not have this patch /sys/devices/system/cpu/cpufreq/boost
Only /sys/devices/system/cpu/cpu0/cpufreq/

Code:

affected_cpus          scaling_cur_freq
cpuinfo_cur_freq             scaling_driver
cpuinfo_max_freq             scaling_governor
cpuinfo_min_freq             scaling_max_freq
cpuinfo_transition_latency   scaling_min_freq
related_cpus                 scaling_setspeed
scaling_available_governors

with Intel Pstate Controller i can not use the ondemand only if i switch to ACPI State Controller
Recommends you change? I chose this combination based on reading some articles of phoronix.com

That part is already well set up, I use overclocked a few years already.

Any tips for the part sensors? When I type sensors in the console appears only that. When I see my share of Windows by the sensors appears over and over temperature readings

Code:

temp1:        +27.8C  (crit = +105.0C)
temp2:        +29.8C  (crit = +105.0C)

Thanks for reply

metaschima · 05-02-2015, 12:42 PM

You should use the 'ACPI Processor P-States driver' (CONFIG_X86_ACPI_CPUFREQ), as this has more features. This and the Core2/Newer Xeon should add the boost option.

In your config

Code:

# CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND is not set

enable it and you will be able to use ondemand.

Run:

Code:

sensors-detect

as root and it will detect more sensors if there are some. Then do what is says as to the commands you need to run such as modprobing drivers.

See the articles for other possible performance improvements.

Candelabrus · 05-02-2015, 02:19 PM

Thanks again.

I understood now about /boost and ondemand i will try

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): yes

metaschima · 05-02-2015, 03:03 PM

You need to enable '/dev/cpu/*/cpuid - CPU information support' in the Processor section 'CONFIG_X86_CPUID'.

Candelabrus · 05-02-2015, 05:27 PM

Ok, i enabled cpuid module and...

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): YES

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): YES
Probing for `IPMI BMC KCS' at 0xca0...                      No
Probing for `IPMI BMC SMIC' at 0xca8...                     No

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): YES
Probing for `National Semiconductor LM78' at 0x290...       No
Probing for `National Semiconductor LM79' at 0x290...       No

Probing for `Winbond W83782D' at 0x290...                   No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): YES
Found unknown SMBus adapter 8086:8ca2 at 0000:00:1f.3.
Sorry, no supported PCI bus adapters found.

Next adapter: NVIDIA i2c adapter 0 at 1:00.0 (i2c-0)
Do you want to scan it? (yes/NO/selectively): yes

Next adapter: NVIDIA i2c adapter 2 at 1:00.0 (i2c-1)
Do you want to scan it? (yes/NO/selectively): yes

Next adapter: NVIDIA i2c adapter 6 at 1:00.0 (i2c-2)
Do you want to scan it? (yes/NO/selectively): yes

Next adapter: NVIDIA i2c adapter 7 at 1:00.0 (i2c-3)
Do you want to scan it? (yes/NO/selectively): yes

Next adapter: NVIDIA i2c adapter 8 at 1:00.0 (i2c-4)
Do you want to scan it? (yes/NO/selectively): yes

Next adapter: NVIDIA i2c adapter 9 at 1:00.0 (i2c-5)
Do you want to scan it? (yes/NO/selectively): yes

Now follows a summary of the probes I have just done.
Just press ENTER to continue: 

Driver `coretemp':
  * Chip `Intel digital thermal sensor' (confidence: 9)

Do you want to generate /etc/sysconfig/lm_sensors? (yes/NO): yes
Copy prog/init/lm_sensors.init to /etc/init.d/lm_sensors
for initialization at boot time.
You should now start the lm_sensors service to load the required
kernel modules.

Unloading cpuid... OK

Run

Code:

modprobe coretemp

as root. Check '/etc/init.d/lm_sensors' for any other modules that need to be loaded.

It will work if you have the 'SENSORS_CORETEMP' module enabled in the kernel, which I see that you do not, so enable it first. In fact I recommend enabling all the hardware monitoring modules there.

I needed to enable this option in the kernel before running. thank you

Core 3:         +25.0C  (high = +80.0C, crit = +100.0C)

How can I make this automatic?

And other temperatures as motherboard, memory, hard disk?
I installed HARDiNFO program but on the sensors shows nothing.

Edit:
Another thing, I did what you said, I moved to ACPI Processor P-States driver (X86_ACPI_CPUFREQ) and put Ondemand.

It happened what you said, appeared to boost option in / sys / devices / system / cpu / cpufreq / boost and was already 1 but monitoring the frequency I realized that is just 3.4GHz or the boost is not working. But using the Intel P States with powersave or performace frequency arrives at 4.5GHz as I determined by the motherboard.

Here one picture

How to fix this?

metaschima · 05-02-2015, 08:49 PM

See the output of 'cpufreq-info'.

Also read about turbo boost:
https://en.wikipedia.org/wiki/Intel_Turbo_Boost

You can add

Code:

modprobe coretemp

and whatever other modules are in the file 'sensors-detect' generated to '/etc/rc.d/rc.local' and they will be loaded every boot.

The HDD usually has the temperature as part of the SMART system. Run 'smartctl -a /dev/sda'.

If you want more sensors, enable all the hardware monitoring modules and run 'sensors-detect' again. Say no when it says to 'generate /etc/sysconfig/lm_sensors', instead it will output the modules you need to modprobe to the terminal, add these to '/etc/rc.d/rc.local'.

The nvidia card usually has a sensor too, but sometimes it can only be accessed from within 'nvidia-settings' or other nvidia sensors program.

Candelabrus · 05-02-2015, 10:36 PM

Thanks again @metaschima i learned to much with you.

Dont have a program that shows all temperatures from my computer? Like HWMonitor?

Let me then make a summary of what could and missing
OK: I got the temperature of processors with sensors (I enabled in the kernel)
OK: I got the temperature of my vga with nvidia-settings
OK: I got the temperature of my HD's with smartctl -a /dev/sdx

OFF: Lack the temperature of my Memory RAM and my motherboard.

Code:

acpitz-virtual-0
Adapter: Virtual device
temp1:        +27.8C  (crit = +105.0C)
temp2:        +29.8C  (crit = +105.0C)

This temperature measuring is who?

metaschima · 05-03-2015, 08:27 AM

Here is your processor info:
http://ark.intel.com/products/75048/...up-to-3_80-GHz
This means that acpi-cpufreq actually uses the correct frequency (3.4 Ghz), unless you are overclocking. With boost it will go to 3.8 GHz temporarily. Did you overclock it to 4.5 Ghz ?

Check the BIOS as it usually has a list of temperatures and what these temperatures are measuring. It is likely they are mobo temperatures.

You may be able to get voltages on the mobo if you enable the voltage monitoring modules, but I have not heard of RAM temperature monitoring.

Also try:

Yes. My stock frequency is 3.4ghz with boost 3.8ghz, but i use so for some time @ 4.5ghz i have one Corsair Hydro Series H110 to keep low temperatures

I will try to compile this program psensor

Oh, ok, I guess you have to use the the Intel P states driver if you are going to be overclocking.
