[Atom/Gemini Lake] `modprobe corefreqk` fails with system stall, Segmentation fault and trace in kernel log/ `dmesg`.

Problem description

Trying to insert the module corefreqk fails with sime call traces in the kernel log, a few seconds system stall and a subsequent segmentation fault of modprobe:

modprobe corefreqk:
[few seconds system stall]

Segmentation fault

Not reproducible without reboots since subsequent invocations of modprobe corefreqk just seem to not terminate without system stall and without other noticeable effects.

Relevant parts in dmesg:

Addendum: corefreqk is loaded afterwards according to lsmod, and cannot be unloaded ("Module corefreqk is in use").

Addendum 2 (the edit functionality here on github does not work for me, so I have to add posts):

corefreqd start up afterwards without complaining;

Sorry for this issue. First time I have a report from Gemini Lake
Bug has to be found on the Gemini Lake call flow starting at: https://github.com/cyring/CoreFreq/blob/39953f71d2ed5cde1ec80c72c642f7f2c74d60ab/corefreqk.h#L6430
Probably one/some registers are not available or wrongly used.
To debug, could you start the driver with the most generic architecture identifier: https://github.com/cyring/CoreFreq/blob/39953f71d2ed5cde1ec80c72c642f7f2c74d60ab/corefreqk.h#L5311

Start the driver, directly from the build directory, like:
```
insmod corefreqk.ko ArchID=11
```
If no issue dump into kernel log, proceed with Daemon and Client

Hey,

Thanks for that instructions!

Though, I cannot do it right now, because I will not reboot my machine for some time. I need it for productivity, and reboot (instead of suspend to disk) would impact that. And without reboot I cannot reload the module.

So this has to wait some time.

Regards!

floor

Looking at the RCX register = 0x395 is the Uncore fixed performance counter which exists since SandyBridge but not for Gemini Lake.

https://github.com/cyring/CoreFreq/blob/39953f71d2ed5cde1ec80c72c642f7f2c74d60ab/intelmsr.h#L113

Back tracing the call flow, MSR error may happen at this line:

https://github.com/cyring/CoreFreq/blob/39953f71d2ed5cde1ec80c72c642f7f2c74d60ab/corefreqk.c#L9357

That faulty MSR call has to be commented in corefreqk.c

#define PKG_Counters_Haswell_ULT(Core, T)               \
({                                  \
    RDTSCP_COUNTERx7(PUBLIC(RO(Proc))->Counter[T].PTSC,         \
        MSR_PKG_C2_RESIDENCY, PUBLIC(RO(Proc))->Counter[T].PC02,\
        MSR_PKG_C3_RESIDENCY, PUBLIC(RO(Proc))->Counter[T].PC03,\
        MSR_PKG_C6_RESIDENCY, PUBLIC(RO(Proc))->Counter[T].PC06,\
        MSR_PKG_C7_RESIDENCY, PUBLIC(RO(Proc))->Counter[T].PC07,\
        MSR_PKG_C8_RESIDENCY, PUBLIC(RO(Proc))->Counter[T].PC08,\
        MSR_PKG_C9_RESIDENCY, PUBLIC(RO(Proc))->Counter[T].PC09,\
        MSR_PKG_C10_RESIDENCY,PUBLIC(RO(Proc))->Counter[T].PC10);\
                                    \
/*  RDCOUNTER   (PUBLIC(RO(Proc))->Counter[T].Uncore.FC0,   \
            MSR_SNB_UNCORE_PERF_FIXED_CTR0 );*/     \
})

Once above change applied, fully rebuild/force-unload/reload the driver:
```
rmmod -f corefreqk
make clean all
insmod corefreqk.ko
```
Oftenly, a wrong register call may leave Processor in a bad state. Force unloading the driver won't help and system has to be rebooted

Sure, whenever you can and w/o Production running.

First, for safety reasons I strongly recommend that the module fails to load on non-tested architectures unless some force-load module parameter is given.

Attached a .patch which applies that changes,

Once above change applied,

'make clean make insmod corefreqk.ko` (on a freshly rebooted machine):

Works.

./corefreq-cli seems to show useful stuff; I haven't looked into everything; voltage and power readings for example stay empty.

-- Machen ist wie wollen, nur krasser.

According to the Intel SDM: 2021-04-05-225612_866x145_scrot

So I'm now routing all Gemini Lake entries to Silvermont.

Can you please try the new version 1.84.4 of CoreFreq in the develop branch ?

I understand it's a lot asking to try again and risk another crash, but it will help the project if you can run the develop branch in which I have made that Gemini Lake as a basic Silvermont because they are sharing the same registers, according to the SDM specs.

Can you tell me how I get this branch? I don't know git more than git clone and git pull.

Github: delete any previous downloaded directories of CoreFreq , next clone again from the development branch
```
git clone [url] --branch [branch] --single-branch
```
where [url] is replaced by https://github.com/cyring/CoreFreq and [branch] is develop
Build and start CoreFreq the ordinary way (no driver parameter) for automatic processor architecture detection.

(Smartphone edit)

Can you please try the new version 1.84.4 of CoreFreq in the develop branch ?

git clone https://github.com/cyring/CoreFreq --branch develop cd CoreFreq make insmod ./corefreqk.ko

MSR_FSB_FREQ (0xcd) is the error. GDM Plus: only registers from tables 2.6, 2.12, 2.13 and probably other IA and compatible MSR. Tremont may also crashed. I need to access and develop directly on these architectures.

Hello, I'm refactoring Goldmont and subsequent architectures (Gemini Lake) Can you please get the latest commit from develop and try again ?

git pull

make clean all
insmod corefreqk.ko
## if no error happened then proceed with daemon and client
./corefreqd -d
./corefreq-cli -s -m -R -c 1 -i 1 -g 1 -C 1

Sorry, I do have no capacities anymore to do frequent testing & communication.

If you have done major work, than I can test for you.

Regards!

-- Vernunft, der Erfahrung wie des Nachdenkens soll man nur mündlich verhandeln. Das ausgesprochene Wort ist sogleich tot, wenn es nicht durch ein folgendes, dem Hörer gemäßes, am Leben erhalten wird. Man merke nur auf ein geselliges Gespräch! Gelangt das Wort nicht schon tot zu dem Hörer, so ermordet er es alsogleich durch Widerspruch, Bestimmen, Bedingen, Ablenken, Abspringen und wie die tausendfältigen Unarten des Unterhaltens auch heißen mögen. Mit dem Geschriebenen ist es noch schlimmer. Niemand mag lesen als das, woran er schon einigermaßen gewöhnt ist; das Bekannte, das Gewohnte verlangt er unter veränderter Form. Doch hat das Geschriebene den Vorteil, dass es dauert und die Zeit abwarten kann, wo ihm zu wirken gegönnt ist. -- Goethe, Maximen und Reflektionen, Nr. 583

Great! Apparently no more crash. Other things could be improved but that will claim a lot of your time with testings. Feel free to close the issue.

Feel free to close the issue.
