Libbpf releases are only loosely synchronized with kernel releases,
and it's only due to current convention we established within
community. There is nothing preventing multiple releases of libbpf
between two releases of kernel. So having Linux distributions use
Github's release tags ensures that all of them are building from
exactly the same source code version.

It is mostly a direct mirror, with some extra Github-specific stuff
beside (like Travis CI testing, etc). All the libbpf source code fixes
do go through bpf-next tree, though.

But the point here was that libbpf itself is not built with any
particular kernel version in mind. It is by design possible to use the
very latest libbpf against a pretty old kernel version and this will
work: libbpf will degrade some of the features (e.g, BTF type info
associations), but everything will keep working otherwise (unless user
requests feature that requires latest kernel version, of course: in
that case BPF program will fail to load and libbpf will return
corresponding error code).

Not sure what you mean by this. We can't have Travis CI integration w/
bpf-next source tree. But we can and we have it for Github mirror,
which runs tests and static analysis for every sync pull request. We
already have and are enhancing at the moment our testing set up to
test multiple kernels in multiple environments.

Hi the task_structure is defined on :
ksoftirqd file kernel/softirq.c
current file arch/x86/include/asm/current.h
curr->rq on rq structure and others

When you need to ensure as task is running need to read alls these variable and
is fortune if task is running , fortune when this  variables is actualised
correct, on conclusion bib, big mistake.

If checking if the regression was introduced in a version earlier than
5.4.8-1 sounds interesting or fun, or if you'd like to test your
hypothesis, then packages from the following may be useful for
coarse-grained bisecting:

  https://snapshot.debian.org/package/linux/

I'd start here:

Some people are complaining on the Internet but there is no explanation about 
this.
A priori, deactivating TPM could do the trick but I'm not sure it's a good 
idea...

Any thought about it please? :)

I've just upgraded my kernel 4.19.0-6-amd64 to backports longterm 
5.4.0-0.bpo.2-amd64 because I had issues with light-docker.
The aforementioned journalctl entries have been reassigned from crit/2 to 
warning/4!
Maybe it's not so serious? ^^

Re: Recurrent alerts "Package temperature above threshold, cpu clock throttled"

Hi Nicholas, all,

Thank you very much for your answer and sorry for my delay...

I've just deactivated hyperthreading in my UEFI.
Still the same warnings in journalctl :(

At least, Internet resources indicate that's it's safer this way with HT 
deactivated (regarding MDS attacks) but I don't know (and really not anyone as 
it really depends on current CPU tasks) how my performances are impacted now...
In your case, it seems to be a benefit but surely it's not always the case...
Maybe I can just continue like this and restore HT if this is impossible to 
live with ;)

I've seen at least 2 ways to deactivate turbo boost:
1) echo "1" to /sys/devices/system/cpu/intel_pstate/no_turbo
Visibly, as sysctl only works with /proc/sys (and not /sys), this needs to be 
set permanently via a systemd service. What do you think about this procedure: 
https://blog.christophersmart.com/2017/02/08/manage-intel-turbo-boost-with-systemd/?
2) modify MSR registers via wrmsr (https://askubuntu.com/a/619881). I don't 
know if there is persistance here...

Do you use any of these? Something else?

PS: My CPU is Intel(R) Core(TM) i7-8565U CPU @ 1.80GHz.
PPS: Even if it works, I don't know if I'm not gonna lose some more 
performances...

Actually my main questions are: 

i) Are those temperature warnings legitimate?
I mean maybe those warnings have been wrongly triggered because probes are not 
accurate? I'm not speaking about HW failure (my laptop is brand new) but maybe 
I just don't have the right driver somewhere...
Indeed, it would be too bad to decrease all my performances with HT/turbo-boost 
disabled (security apart) whereas the journalctl warnings are wrong 
initially... ;)

PS: I have installed intel-microcode 3.20191115.2~deb10u1. Still the same 
issues.
I don't know if it's an issue but microcode module is blacklisted in 
/etc/modprobe.d/intel-microcode-blacklist.conf (it seems to be a precaution 
regarding unsafe updates).

ii) Is it risky to do nothing about these temperature warnings?
I have no idea what EC means (Embedded Controller?) but you said EC eventually 
shutdowns the laptop if need be. I presume it's not really beneficial from the 
user point of view as the current tasks will be shutdowned and some work/data 
might be lost during the process.

Thanks again & Best regards :)

Bug#926794: linux-image-4.19.0.0-bpo.4-amd64: Please enable FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER in kernel config

I just stumbled over this and became curious.

Since i currently just directly boot the kernel via EFI stub i followed 
https://wiki.debian.org/BuildADebianKernelPackage and did give it a try.
I was quite satisfied with the result.

Are there any situations where this makes something worse?
( I see Ben tested this:

It's a bit depressing to see bugs hidden under the carpet instead of
solved.  But whatever.  If you prefer adding a bug in mkinitramfs
instead of fixing the problem, then I guess that's your decision.

If anyone is interested in solving the kmod bug, then that is as simple
as deleting a Debian patch,  Which BTW seems to have been added in for
the exact same reason:  To hide another bug.

Nice work
