Using last commit, you will need to add the Experimental argument when loading the driver.
insmod corefreqk.ko Experimental=1
Temperature is a raw value without decimal adjustment.
May crash, save you files.

6 years ago With the latest commit and insmod corefreqk.ko Experimental=1 I get non-zero temperature values, but they are static and don't seem to make sense:
Also, for both the latest and previous commits:
nmi_watchdog=0 kernel parameter.$ cat /proc/cmdline

*/ p-state ratios enumeration differs from previous screenshot. Max was 41 and now 30 => reason of segfault. Max ratio can be obtained during driver startup (insmod corefreqk.ko) if full load is applied simultaneously or governor set to performance.
*/ temp is so far a raw debug value. I need now to apply offsets. Do you have any Celsius reference (BIOS or other value) I can compare with ? (sampled at the same period)
adatum
commented
6 years ago You're welcome. Thanks for the quick development.
Does insmod corefreqk.ko have to be done at the time of max expected ratio? Is a fix or workaround possible/likely? Max ratio can go above 41, depending on the number of cores stressed, boosting algorithms, and potentially manual overclocking.
There is a CPU temp readout from sensors/psensor (lm-sensors doesn't find any sensors):
$ sensors
asus-isa-0000
Adapter: ISA adapter
cpu_fan: 0 RPM
nouveau-pci-0900
Adapter: PCI adapter
temp1: +44.0°C (high = +95.0°C, hyst = +3.0°C)
(crit = +105.0°C, hyst = +5.0°C)
(emerg = +135.0°C, hyst = +5.0°C)
k10temp-pci-00c3
Adapter: PCI adapter
temp1: +52.0°C (high = +70.0°C)
It's certainly not perfect (no fan rpm) but it's the only way I have found so far to get a CPU temp reading in linux. At least kernel 4.16.6 fixed the offset (previously off by 49C or 59C).

6 years ago I commit a change of the sensor register. Can you please post the value.
Remark: it is a debug value, not meaningful yet.
adatum
commented
6 years ago The Min/TMP/Max values are back to 0.
cyring
commented
6 years ago Ok, let's try now with the index register commit
adatum
commented
6 years ago Now the TMP value fluctuates. Max/Min are fixed. Sometimes the TMP value reads 0. The digits of the values have different colors depending on the column position, possibly for denoting decimals? Some shifting and truncation can change meanings between eg. 10(27), 102(77) in the images below:
cyring
commented
6 years ago The purpose of this new change is to:
Based on BKDG Family 16h, I need for Family 17h , Ryzen(s), the confirmation of the Reported Temperature Control register specification to conditionally select the right constant offset (49) according to the RangeUnajusted bit.
adatum
commented
6 years ago There is a reading for only 1 core now. Max seems to behave as expected. Min is still 0. TMP seems to be off by 10-11C compared to psensor. Is there anything you would like me to check specifically?
Maybe these links have useful info?
Ryzen 2700X has a temperature offset of 10 degrees C. If bit 19 of the Temperature Control register is set, there is an additional offset of 49 degrees C.

6 years ago Thermal adjustment added.
There is only one sensor for all cores in those processors, but what about Threadripper: 2 registers ?
adatum
commented
6 years ago Now TMP matches sensors/psensorand Min/Max behave as expected. Reporting is still for one core only.
I started using the it87 kernel driver for sensors and it looks like CoreFreq is matching temp1 rather than k10temp. Is there a way to check?

k10temp-pci-00c3

temp1: +52.2°C (high = +70.0°C)Nice to see we have the expected results. CoreFreq employs the same register than k10temp.
2 sensors exist in this AMD PCI space : die and hardware temperatures.
As states previously, the sensor is unique for all cores. In your screenshot, the temperature is queried by the cpu #6 which is the current CoreFreq driver service cpu ; I called it the service processor on which some driver handler, daemon threads and UI are bound to, for atomic synchronization reasons. The service processor may change at startup or if the associated cpu is disable, but in any case the temperature query will migrate to the new service cpu number.
With Intel we get one sensor per physical core.

6 years ago I read somewhere that there are many CPU temperature sensors, but perhaps they are not exposed externally.
That roadmap is fantastic.
Would it be feasible to add:
Of course we can make separate issues for them.
adatum
commented
6 years ago It's easier to see the temperature difference between temp1 (dark green) and k10temp (orange) when stressing a single core:
I wanted to check which reading CoreFreq corresponds to, but it segfaults when trying to launch with single core stress tests. It launches fine when all cores are stressed.
cyring
commented
6 years ago Seg fault happens in the UI due to a buffer overflow: the histogram is going far away from the max known ratio (41) --> XFR ratio is missing.
Can you run and post result of corefreq-cli -s
You will notice that the highest ratio is 41 but this processor is able of 43 : the XFR frequency reached with a single core, I guess.
The remaing task is then to find the right register to query such ratio for all Ryzen series.
adatum
commented
6 years ago Yes, on single core it can reach 4.35GHz (or more with watercooling). Though I'm not sure of the multiplier/ratio and base/bus clock combination for that. Some OC modes on some motherboards can change the bus clock from the default 100MHz to a bit more (or less), so that's another variable.

So, the max ratio means that the first msr register MSR_AMD_PSTATE_DEF_BASE has a significant frequency id which reflects the BIOS setting.
And when XFR is enabled, this register holds the max none turbo coefficient.
40 vs 37
An XFR status bit or equivalent has to be queried.

6 years ago Glad it's useful.
The explanation is beyond my understanding, but let me know if there's anything else you need.
cyring
commented
6 years ago A stress function will loop over the current frequency to reach the XFR or the max ratio. One unit is added to the result.
1- Set BIOS frequency to auto (with XFR and Boost) 2- Load driver when system load is idle
Kernel scheduler may stall, save your files !
cyring
commented
6 years ago Could you also check the UI if TURBO is light on ? In both cases : 1- Enable in BIOS 2- Disable in BIOS
Thank you

6 years ago I get an error (not system crash) with $ sudo insmod corefreqk.ko Experimental=1: "watchdog: BUG: soft lockup - CPU#13 stuck for 22s!". (CPU # can vary) Loading the module takes several seconds and htop shows 100% cpu usage on only 1 core. Eventually the command exits and I'm able to run corefreqd and corefreq-cli.
CoreFreq hasn't crashed so far. It was started at idle.
Turbo indicator is lit. Haven't tried with CPB/PE/PBO disabled in BIOS yet.
Screenshots below at idle, single core loaded, all cores loaded. Also output of corefreq-cli -s. Turbo Boost printout for 1C/2C/3C doesn't seem right.

Need to find another way to estimate or query the highest ratio...
adatum
commented
6 years ago Thanks. Since it seems like the cores are being briefly benchmarked to establish max frequency/ratio, do you think it would be possible to rank the cores (best to worst)?
Note that I accidentally had enabled "Ai Overclock Tuner" in the Asus BIOS which caused the 100.6MHz base clock in the screenshots above. This also allowed boosting to 4.38GHz which puzzled me initially.
cyring
commented
6 years ago With BIOS combinations of CPB, XFR, Manual OC, can you report the state of TURBO (green or not) ?
I expect to read the TURBO as disable when OC is manual.
adatum
commented
6 years ago Yes, TURBO is grey and not green when CPB, PE, PBO are disabled and using manual OC.
cyring
commented
6 years ago I change for a table of Boost and XFR frequency ratios.
If "AMD Ryzen 7 2700X" is found and CPB is enable on any core then
1C = Max ratio + 6 (Boost) + 2 (XFR)
else (case of manual OC)
1C = Max ratio
adatum
commented
6 years ago Module loads quickly again, and corefreq-cli hasn't crashed so far starting from idle, stressing 1 to 16 cores, going back to idle.
Some limitations:
1C limit (seems unlikely for this CPU). Manual OC isn't affected.The good news is it works, and temperature (+min/max) match sensors
There's a discrepancy in the idle ratios/frequencies compared to watch -n1 "cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq"
cyring
commented
6 years ago Give a look at source code for all other Ryzens: https://github.com/cyring/CoreFreq/blob/b076c248e884b83132303d0b8ee0a2ab5122efba/corefreqk.c#L2559 Only additional beans are hard coded; base P0 ratio comes from the FID register (like the BIOS is doing, I guess). However if CPB is off, because user is overclocking the processor, then this algorithm does not happen and the user's ratio becomes the limit.
Driver arguments can be listed with:
modinfo corefreqk.ko
Start with SleepInterval=100 for the highest accuracy. This will have a CPU overhead b/c of a tight 100 ms loop, but it should match the values of scaling_cur_freq
adatum
commented
6 years ago Nice work. I didn't know you included values for other CPUs as well. The 2200G[E]/2400G[E] are missing though.
SleepInterval=100 gives the same values as before (refreshed much more quickly). I don't know what the lowest ratio is, but I haven't noticed much less than 18 maybe 16 in other tools, though I'm not fully confident of scaling_cur_freq either. Do you know what is the minimum frequency/ratio of the CPU?
cyring
commented
6 years ago 2200G[E]/2400G[E] but also EPYC series are missing into table: I need their exact cpuid brand string, with associated Core Coefficient and XFR ability: +50 or +100 or +200MHz or none Any help to ding those informations are welcomed.
I believe scaling_cur_freq and CoreFreq don't speak about the same subject: immediat vs relative frequency.
In the UI, look at lowest between 2C, 3C and so on
cyring
commented
6 years ago Hello, there is something I can't see in your last screenshot: what is the highest ratio (computed by the driver) ?
adatum
commented
6 years ago The highest ratio indicated in the GUI was 45 I believe.
Sorry I don't understand; what do you mean by immediate vs relative frequency? Seeing ~100MHz vs ~2GHz... they can't both be right or they are measuring different things. Since this is frequency and not a percentage I would think they should match.
cyring
commented
6 years ago BIOS P-states guide. If you have such options, it could be interested to check P1, P2 ... Pn against 2C, 3C, nC
cyring
commented
6 years ago Here is the alpha code for the power energy and the voltage core. Remark: those are per Package readings.
In the UI, go to the view [Power & Voltage] to verify: 1- the VID and the computed Vcore 2- the Package and Cores Energy and Power consumed. (no Uncore and Mermory)
Open the window [Power & Thermal] to display the Units.
Could you also check that the temperature is still showing up and print the Processor topology ?
corefreq-cli -m
Thank you.
adatum
commented
6 years ago I'll check P1.. Pn next time I'm in the BIOS.
VID and Vcore show up but remain constant. No change whether idle or full load. Energy and Power are zero. Units are displayed in [Power & Thermal] window.
Temperature still works.

rdmsr: CPU 0 cannot read MSR 0x0005a000Also, I checked the P-states:
P0: 3700, 1.21V P1: 3200, 0.99V P2: 2200, 0.81V P3: 400, 0V
Not defined for P4-P7. The 0V for P3 caught my eye. But I really know nothing about P-states.

6 years ago 1- New voltage VID reading delivered 2- About RAPL (running average power limit), I'm not sure if the Ryzen counters work like the Intel ones; cumulative or instantaneous ?
First I'd like to say I'm really impressed by this software. I've been looking for a lightweight program to monitor frequency (and hopefully temperature, vcore, etc) while I set up a new system, and CoreFreq works well and has a ton of features. Plus, I like that it runs in the terminal.
Now for the issue: there is currently no reporting of temperature, Vcore, or power on the Ryzen 2700X as can be seen in the following screenshots.
The 2700X is a new CPU so it is understandable. If you need info or want me to try something, just let me know.
Even in the current state, CoreFreq is useful to me. Again, really impressed. It deserves more publicity!
