According to the crash:
[ 619.939065] RIP: 0010:BaseClock_Core+0xe/0x90 [corefreqk]

... MSR_FSB_FREQ (0x00000000000000cd)
appears to be not supported on Goldmont Plus
Can you check its support as bellow ?
rdmsr -ax 0xcd
Can you also provide me the CPUID from /proc/cpuinfo
?
I just need cpu family
model
stepping
model name
from first CPU
Unfortunately it is not supported: rdmsr: CPU 0 cannot read MSR 0x000000cd

I need the first crash log.
Can you please run again without ArchID
. I mean just a basic insmod corefreqk.ko
then post the kernel log from RIP
to </TASK>
.
I couldn't recover an actual log since the kernel panicked, but here is a picture of my screen when I ran insmod
on tty3:
Oh MSR_TURBO_ACTIVATION_RATIO
is not available on GDM+
Can you try:
rdmsr -ax 0x64C
It cannot read that register.
In function PerCore_Goldmont_Query()
of corefreqk.c
file, please comment Intel_Turbo_Activation_Ratio
https://github.com/cyring/CoreFreq/blob/5a84d5fc8d7dce149e547349c7971d7af5c49128/corefreqk.c#L12017
static void PerCore_Goldmont_Query(void *arg)
{
/*
Intel_Turbo_Activation_Ratio(Core);
*/
}
Save, rebuild, try
make clean all
insmod corefreqk.ko
That resolved the issue! insmod
worked immediately and CoreFreq is now working!

I believe it's the first time seeing CoreFreq with your architecture because this MSR is mentioned compatible since Goldmont (non Plus)
Do you have any option in BIOS which prevents from using it ?
I don't believe so. Intel TurboBoost is enabled.
I don't believe so. Intel TurboBoost is enabled.
OK, I'm programming a specific entry for GDM Plus...
Cool!
For your testings you can now pull the develop
branch to get the fix.
Could you fulfill a Wiki support of your processor ?
You can take as an example one of those intel-laptops entries.
At least corefreq-cli -s -n -m -n -M -n -C 1 -n -c 1 -n -g 1
Latest commit is working as expected, thanks! Also, here is my gist for the wiki page: https://gist.github.com/N0tACyb0rg/c34b592adb6507c0fb51b430f56d8627
I should had tell you about the gist page:
Thank you
Remaining issues observed in the output
Can you read this register in two cases: Idle CPU next Loaded CPU
## IA32_PERF_STATUS
rdmsr -ax 0x198
Then simply read C-States BAR
## MSR_PMG_IO_CAPTURE_BASE
rdmsr -ax 0x000000e4
In [Geminilake]
section, change the voltage formula:
https://github.com/cyring/CoreFreq/blob/9e80cbf9828aac23f977a1e650e91213472e9d31/corefreqk.h#L8745
With:
.voltageFormula = VOLTAGE_FORMULA_INTEL_SNB,
Using your dump VID of 6512
, you will get a Vcore about 0.7949V
Stress processor and check if the Vcore is matching specs.
For your testings, all pending changes are inside this archive: Be prepared for a crash, save your files before loading the driver.
Alright, I downloaded the provided archive and got it all set up. Everything worked immediately. The only thing I noticed was that the VID value is only displayed on one CPU core (001 to be precise). The vcore is around 0.7949 though. All the voltage stuff is only being listed for one core though (001 again).
Now with the registers, both return values. rdmsr -ax 0x198
returns 268f00001a00
for all cores, and rdmsr -ax 0x000000e4
returns 0 for all cores.

Latest Gemini Lake
changes are now committed into the develop
branch.
Based on MSR IA32_PERF_STATUS[48-32]
and formula Vcore = VID / 8192
VID | Vcore (V) |
---|---|
6512 |
0.7949 |
9871 |
1.2049 |
You can change, as will, the Voltage scope in the Settings
window,
next from Menu or shortcut V
, switch to the Voltage
view:
Usually the VID is common for the whole Processor package but if your observations reveal discrete voltage per Core or per Thread (SMT) then let me know, I'll make it as a default.
Could you also post here a full output as bellow:
corefreq-cli -s -n -m -n -M -n -C 1 -n -c 1 -n -g 1 -B -n -k
and screenshot the main Frequency
view next Sensors > Power
view while Processor is idled then stressed.

The memory controller output is quite confusing to me. Here is a table of the specifications I was able to find from Dell (the maker of my laptop):
I have the 8 GB configuration.

You mean the Vcore always remains at 0.7999V

If not, can you please show me when it reaches its max value. I would like some screenshots of the Voltage view, like those:

Programming an IMC decoder will be a long road... First we need the Gemini Lake - Goldmont Plus - Pentium N series datasheet volume 2 with all IMC registers.
Would this work? Potential Datasheet
I found items about the memory controller on page 71 of that PDF.

It's encouraging: MCHBAR
can be remap like I did with Skylake
But some primary timings were not found. Ex: tCL
?
Based on datasheet, I've a bunch of Host Bridge Registers I need them to be dump: are you available for this ?
Yes I am.
Yes I am.

I'm reviewing the code to dump but I don't find what's wrong.
This new archive, the function is called DumpMemoryBAR
in corefreqk.c
file.
Remark: I've removed the IOMMU from the dump. Does not make a difference.
For example, I'm dumping from an Ivy Bridge processor which follows the same rule to remap in kernel space the MCHBAR
happening in function Router
Here's the dump:

Major difference is IVB has MCHBAR
offsets starting at 0x4000
.
Remark: in this example, I'm stopping at 0x4010
; max of two possible IMC channels; displacement between channels is 0x400
In Gemini Lake datasheet volume 2, the offsets are specified at 0x1000
, displacement is 0x200
, I see four channel spaces: 2 for LPDDR4 or 2 for DDR4
So I don't understand why the N5000 dump is full of 0xffffffff

System Info:
I compiled from the develop branch with the provided make command for Intel systems:
make MSR_CORE_PERF_UC=MSR_CORE_PERF_FIXED_CTR1 MSR_CORE_PERF_URC=MSR_CORE_PERF_FIXED_CTR2
. I then attempted to insertcorefreqk.ko
usingsudo insmod corefreqk.ko
and got a kernel panic. I tried testing it by inserting it using the suggestion in #227,sudo insmod corefreqk.ko ArchID=11
and got a segmentation fault instead of a kernel panic. Here's the log for that from dmesg: pastebin.
