(Re-sent, as I think I had the wrong mailing list address before)

I'm running Linus' latest master of today (and have seen this for a while
now). I've got an IceLake CPU (i7-1065G7 running on a Dell 7390 2-in-1, but
I'm pretty sure I've seen issue this on my HP Spectre 13 with a 9th-gen CPU).

Sometimes when I boot, I get 4 RAPL "fixed counters" and sometimes I only
get 3, and it's always the "psys" domain that's missing when it does. See
attached output from various dmesg runs (and a snippet below).

Is this a bug?
Do you know what may cause this?

If you need more info to help me help you guys with this (if it's truly an
issue), please let me know.

Thanks,

	-Kenny

Well, it didn't, but why not?

Here's the "3 counters case" (same running kernel as above):

$ sudo egrep -r . /sys/class/powercap/intel-rapl*/name
/sys/class/powercap/intel-rapl:0:0/name:core
/sys/class/powercap/intel-rapl:0:1/name:uncore
/sys/class/powercap/intel-rapl:0/name:package-0
/sys/class/powercap/intel-rapl-mmio:0/name:package-0
$

As soon as I get "4 counters" numbers I'll resend with those values.

OK, for the "3 counters" case (as per my last E-mail):

CPU 0 MSR 0x65C value: dd0000
CPU 1 MSR 0x65C value: dd0000
CPU 2 MSR 0x65C value: dd0000
CPU 3 MSR 0x65C value: dd0000
CPU 4 MSR 0x65C value: dd0000
CPU 5 MSR 0x65C value: dd0000
CPU 6 MSR 0x65C value: dd0000
CPU 7 MSR 0x65C value: dd0000

"4 counters" (i.e., with the "psys domain" being found) results coming up soon.

OK, so I rebooted after a power cycle, and here's the results with 4
fixed counters (i.e., it sees the "psys domain"):

Here's the "4 counters" case:

MSR value on CPU 1 for 0x64D is: 10793e2
MSR value on CPU 2 for 0x64D is: 1079512

OK, so here's that for the "4 counters" (with the "psys domain") case:

MSR value on CPU 0 for 0x65C is: dd0000
MSR value on CPU 1 for 0x65C is: dd0000

So I just tested a few shutdown vs. reboot cycles, and if I reboot, I only
get three counters. If I shutdown, then restart, I get 4 counters (including
the "psys domain" one).

I tried it on a few kernels, including the oldest one that comes with my
distro (5.3.0-40-generic) where all the RAPL stuff is made as modules.

So, maybe we're not "clearing" (wild guess here) the "psys" RAPL on a reboot,
something that would happen on a cold boot? (I'm afraid to say the "B-word",
as that would mean it's a Dell issue so I won't hold my breath waiting for
a fix).

When you say counters, where is this missing from:
1. /sys/class/powercap/intel-rapl/intel-rapl:1
2. /sys/bus/event_source/devices/power/events/
3. Both of the above folders

Also what do you see?
rdmsr 0x65c
rdmsr 0x64d

Thanks,
Srinivas

CC Kan.

By checking the RAPL PMU code, it is possible that rdmsr_safe fails
when reading MSR_PLATFORM_ENERGY_STATUS.
But we don't have any debug message showing the exact failure reason.

can you please apply the patch attached and see why psys probe fails?

thanks,
rui

I could reproduce this. This fails because the Psys MSR read 0. Also
the counter values are not correct as the incremental values are less
than package energy counter values.

OK, so the very night I'd asked this question, Dell put out a BIOS update
(BIOS 1.3.1 03/02/2020) that seems to have fixed this issue; I have not
had a missing "psys" domain since updating. Srinivas, can you update the
XPS 7390 you have to this BIOS version and verify this is fixed?

Thanks,

Do you mean MSR_PLATFORM_POWER_LIMIT?
It is not 0 according to previous emails.

In some platform to set the correct power settings and then control
thermal when there is an issue.

OK. I think a BIOS update from HP that just came thru yesterday seems to
have fixed this issue, BTW.

> What distro you are using?

Kubuntu 19.10 (but I build my own kernels from Linus' master since I have
an IceLake CPU).

I disabled thermald a while ago; it goes overboard and slows me down too much.

> Run this tool once on your system
> https://github.com/intel/dptfxtract

I did that a while ago (back when I was using thermald) and have a bunch of
entries in /etc/thermald/... ; but as I'm no longer using thermald is this
relevant for me? What should I look for?

You will not loose anything if you don't have psys domain. What disto
you are using? Check thermald version (Some distros star this by
default like Ubuntu)
thermald --version

Run this tool once on your system

I tried on the Dell 7390 2-in-1 and see the behavior you reported.
The problem is that the energy counter is 0 during probe (msr 0x64d is
0), which is not correct. So you rmmod intel_rapl_msr and modprobe
again, you will see psys domain.
Even the counter values are not correct. The delta between two reads of
energy_uj is less than the package domain energy_uj delta.
So psys domain is not useful on this system.

Sent again as the original email was not plain text.

Thanks,
Srinivas
