@jani, @timojyrinki, this is how I've now sorted out my earlier rant. No idea what I'm doing but I don't neither care that much ;-)

I don’t really understand the cause and effect here but I finally got rid of “GPU HANG” issue with #i915, i.e.

Jul 02 21:20:50 suppilovahvero kernel: i915 0000:03:00.0: [drm] GPU HANG: ecode 12:1:84dfd7f7, in ChaosGate.exe >
Jul 02 21:20:50 suppilovahvero kernel: i915 0000:03:00.0: [drm] ChaosGate.exe[40919] context reset due to GPU ha>

I did the following:

1. Teared my machine into parts.
2. Cleaned up everything
3. Put some new cooling paste.
4. Bought and switched a new PSU.
5. Created /etc/modprobe.d/i915.conf and run sudo dracut --force (in Fedora).

The contents of /etc/modprobe.d/i915.conf are the following:

options i915 enable_guc=3
options i915 enable_fbc=1

I put these there because I found multiple forum posts etc. where this was the suggested solution but obviously I have zero idea what they’re doing 🤷 I’ve played Chaos Gate as a test without hangs, and it used to hang within just few minutes.

It is still a bit weird that #Fedora 40 with its default settings gives such crap results on Intel Arc A770.

@kernellogger Yep, thank you, coming from the Holiday to fix this ;-)

I released v3. The previous version was already fully working and confirmed by Stefan (on the basis that he got the expected log message).

https://lore.kernel.org/linux-integrity/20240704085708.661142-1-jarkko@kernel.org/T/#t

This version I'm likely going to put to a pull request for -rc7 today even without reviewed/tested-by tags because null deference needs to be addressed, there's no excuses not to do it. I'll hold for some hours but then I'll put the PR out.

On the other hand, we can wait "forever" for tpm_ibmvtpm have the feature fully enabled. That endangers the stability of total zero systems in the wild.

@kernellogger v2 with baseline fixed into mainline tip: https://lore.kernel.org/linux-integrity/20240703182453.1580888-1-jarkko@kernel.org/T/#t

@kernellogger I.e. the symptom was correct but the proposed fix was not, and this is the correct way to fix the actual bug.

@kernellogger directly related to https://lore.kernel.org/linux-integrity/55e8331d-4682-40df-9a1b-8a08dc5f6409@leemhuis.info/

Critical fixes for TPM2 authenticated sessions, which I still hope landing to 6.10:

I like to start a bug fix by:

$ git commit -a -s --allow-empty -m "Fixes: 1085b8276bb4 (\"tpm: Add the rest of the session HMAC API\")"
[auth-null d5d3411b52f7] Fixes: 1085b8276bb4 ("tpm: Add the rest of the session HMAC API")

$ git show
commit d5d3411b52f741cb16cfb7180d24f454e97b4570 (HEAD -> auth-null)
Author: Jarkko Sakkinen <jarkko@kernel.org>

    Fixes: 1085b8276bb4 ("tpm: Add the rest of the session HMAC API")
    
    Signed-off-by: Jarkko Sakkinen <jarkko@kernel.org>

So that I get the fixes-line backed up fast :-) Then I just amend the meat.

For generating the fixes line I have:

git-fixes() {
  git --no-pager log --format='Fixes: %h ("%s")' --abbrev=12 -1 $1;
}

#git #linux #kernel

Sometimes while I'm digging around the bowels of PLs, I find websites straight out of the 90s for seemingly active projects:

It’s quite short but does pretty much what I would ever want from a text editor:

$ wc -l .vimrc 
42 .vimrc

Couple more OS/2 screenshots - one in which IBM is explaining us how an office works (or should/could work). See image captions for transcript.
We're in 1994 or thereabouts, if I'm not mistaken. That's 30-ish years ago. I still miss it.

The OpenAI ChatGPT app on macOS is not sandboxed and stores all the conversations in **plain-text** in a non-protected location:

~/Library/Application\ Support/com.openai.chat/conversations-{uuid}/

So basically any other running app / process / malware can read all your ChatGPT conversations without any permission prompt:

@AndrewRadev @realestninja IPC and client-server decoupling = ridiculously overrated and zero gain for the end user

@AndrewRadev @realestninja IPC and client-server decoupling = ridiculously overrated and zero gain for the end user

@AndrewRadev @realestninja and both expect real-time feedback when the data is stimulated by the user 😅 so essentially same piece of software

@AndrewRadev @realestninja what works in digital audio workstations can be claimed to be work also in text editors because both are model data editors for different type of artifacts.

@AndrewRadev @realestninja And a C lib could be then provided for ”LSP host” which would be trivial to integrate to any text editor.

@AndrewRadev @realestninja IMHO plugin based system similar to VST3 and CLAP in audio could be much more ideal architecture. Editor can eg then decide how to organize threads and can have a clock and scheduler which can orchestrate dynamic or even real-time behavior.

Generally speaking, C is pretty straightforward. It takes about 20 days to learn 80% of it, and then no more than 20 years to cover the remaining 20%
