Hello,
I'm helping to test scratch/igc branch on my local environment:
```
❯ uname -a
Linux Matrix 6.6.41 #1-NixOS SMP PREEMPT_DYNAMIC Thu Jul 18 11:21:27
UTC 2024 x86_64 GNU/Linux
```
I get the source code of scratch/igc, commit hash: 6682d0e6c96 .
And I append a new commit:
```
diff --git a/src/igc.c b/src/igc.c
index f069a2becc9..4d792da75c8 100644
--- a/src/igc.c
+++ b/src/igc.c

res = mps_chain_create (&gc->chain, gc->arena, ARRAYELTS (gens), gens);
IGC_CHECK_RES (res);
}
```
Then, I compile it by:
```
make extraclean
./autogen.sh \
&& ./configure \
--prefix=$(realpath ../emacs-build/$(git branch --show-current | sed
's/\//_/g'))\
--with-mps=yes \

--with-dbus --with-native-compilation=aot \
--with-file-notification=inotify\
&& make -j30 install
```
When I launch the emacs, editing rust files, emacs crashed. the backtrace is:
```

You can't do that without a process to debug.
(gdb)
```
What information should I provide to help investigating this crash?
Thank you

AFAIU, the above requests MPS to create a generation chain whose
capacity is 128GB. How much memory do you have on that system?

My total memory is 48GB*2 memory:
```
❯ free -h
total used free shared buff/cache
available
Mem: 93Gi 6.8Gi 75Gi 2.8Gi 12Gi 83Gi
Swap: 95Gi 1.5Gi 94Gi
```
Thank you, I should decrease `mps_gen_param_s` to use less memory.

Those numbers are in kilobytes, so that requests 640 gigabytes of memory
before it'll even start collecting in earnest. In theory, that should
work given enough RAM or swap, but I doubt anyone's tested MPS with such
extreme settings.

How much memory was it using at the time? To me it looks conceivable
the crash happened because we failed to get enough memory for a new
stack frame, but if it's reproducible or happens again after reducing
the generation sizes, we need to investigate it further.

It would be good to know whether 'object' is actually nil in this case
(in which case lisp.h:1198 is wrong) or whether the nil is wrong (and
the lisp.h:1198, possibly, correct), but I suspect the best bet is to
reduce the generation chain sizes and try again.
> What information should I provide to help investigating this crash?
Trying again with a more moderate generation size would be ideal, but
you might want to run Emacs in GDB and keep it connected after a crash
so we can investigate further.
Thanks again

Hello
After I change `mps_gen_param_s gens[] = { { 128000, 0.8 }, { 5 * 128000, 0.4 } };`
to `mps_gen_param_s gens[] = { { 12800000, 0.8 }, { 5 * 12800000, 0.4 } };`, the Emacs never crash again.
And it's RES mem is 2661M, I think it's good, I'm editing 2000 rust files in Emacs with rust-analyzer lsp server. 99% of time I don't feel GC's lag.
But, When I hit `Ctrl + right click`, I feel a very long GC lag ( > 10 seconds). It's reproducible.
So I profiler-start, then `Ctrl + right click`, then `profiler-stop`, got:

When I M-x `menu-bar-mode` to enable menu-bar, the long gc lag (> 10
seconds) happened too.
Then I try `Ctrl + right clock`, then there is no long gc lag (> 10
seconds).

What file are you visiting when this happened?
I see no lag whatsoever here, FWIW (but then I didn't change the MPS
arena parameters to such large values).

What file are you visiting when this happened?
A /home/exec/Projects/git.savannah.gnu.org/git/emacs-build/scratch_igc/share/emacs/31.0.50/lisp/files.el file.
Another information: my KDE plasma setting has a keyboard config.
I config keyboard long press repeat rate as: 100 repeats/s
If I decrease 100 repeats/s to 10 repeats/s, then I feel no gc pause on scratch/igc.
But, in master branch, even I set 100 repeats/s for long press key config. I feel no pause.

And I don't feel any pauses with the igc branch, either.

I'm not sure key repeat is a particularly good test of GC
responsiveness; it appears to be heavily influenced by non-GC factors,
and when holding C-n, redisplay stops at some point and only catches up
when the key is released.
If I set the keyboard repeat rate to 255 using 'xset', which appears to
be the maximum supported, an MPS Emacs running my production session
(some 200 buffers) ends up exhibiting this behavior when holding C-n, so
only the first, non-repeated command is displayed properly. A
newly-launched MPS Emacs does fine with xdisp.c in fundamental mode, but
in C mode it ends up scrolling for a bit, presumably until font-lock
does its work, then not scrolling until 'n' is released again.
It would be nice to change this behavior to force some redisplay even
when Emacs can't keep up with keypresses, but I don't think this is an
MPS issue at this point.
Is it true that we only redisplay once all key presses have been
handled?

I see none of this, but my auto-repeat rate is about 30/sec.

For me, the MPS build is much snappier scrolling through xdisp.c (in C
mode) than the "normal" build.

We redisplay when we get back to the main loop and there's no input
pending. Depending on the input rate and the time it takes to process
each key, it could go either way.

Where is the main loop? Could you please tell me the source code file and line number related to "getting back to the main loop"? I'm interested in the Emacs source code. Thank you.

The main loop is in keyboard.c, in the function command_loop_1.

That's still a very large size for the initial generation, in
particular. May I ask why you decided to do that? I think for
interactive use, you want to keep the initial generation reasonably
small.

Are we sure that it's GC causing this? I assume control + right click
shows a buffer menu, so it builds a list of all buffers, and you have a
lot of them...
I've played around a little creating 10,000 buffers and showing the
buffer menu, and there does appear to be some lag, but this is true both
with and without MPS. I also tried a build with --with-x-toolkit=no,
and that seemed to have less lag.

I cannot tell from this whether MPS was called once and took a very long
time to run, or was called many times and the problem lies elsewhere.
Does the problem happen with the default generation sizes?

When I living in Emacs, I like long press `j` (evil-next-line) and `k` (evil-previous-line) to move around the code.
In master build, long press `j` and `k` are very smooth.
But in mps build, long press `j` and `k` can feel frequent brief pauses.
So I tested whether increasing the number in `mps_gen_param_s` would make long-pressing `j` and `k` smoother. After the test, it did help, but I still feel pauses when long-pressing `j` and `k`.

No, I think the ctrl + right click is not related to GC.

Eval Exec, I see that you're running the scratch/igc branch in Nixos.
Do you have a nix expression or flake for building scratch/igc on Nixos,
or did you do it imperatively? I'm looking to test it too.
