Asus chromebook CX550 crashes during boot on v5.17-rc1 kernel.
The root cause is null pointer defeference of bi_next
in tgl_get_bw_info() in drivers/gpu/drm/i915/display/intel_bw.c.

BTW this code makes me rather suspicious overall. num_planes==0 means
no planes can be enabled at all. Is that even correct? IIRC the icl
code did not have qgv points that had num_planes==0.
Also IIRC I added that 'num_planes = ... + 1' to the icl code
ot make it actually sensible. The icl sample code didn't have
that +1 and instead it used '>' as opposed to '>=' in the
comparison to the actual number of enabled planes thus
implying the +1. But now here in the tgl+ code we have the
+1 for in one branch of the if, but the other branch just has
a 0 (so no +1).
And it doesn't help that the code is doing this weird [i] + [i+1]
stuff inside the single loop. Would be a lot more legible if we
just did two loops I think. Though I see the same awkward construct
is used in spec sample code as well.

(Some email path may be clogged; Nathan Chancellor has also sent email,
but I wanted to comment too.)
This patch solves https://github.com/ClangBuiltLinux/linux/issues/1626
And it's actually fixing a wild write as well: for folks where
"i < num_groups - 1" is false and they don't get "lucky" with a NULL
deref, this is writing to some address left over on the stack. :|

Was this patch ever applied or was the issue fixed in a different way?
If CONFIG_INIT_STACK_ALL_ZERO is enabled (it is on by default when the
compiler supports it), bi_next will be deterministically initialized to
NULL, which means 'bi_next->num_planes = 0' will crash when the first if
statement is not taken (i.e. 'i > num_groups - 1'). This was reported to
us at [1] so it impacts real users (and I have been applying this change
locally for six months). I see some discussion in this thread, was it
ever resolved?

The patch was not accepted by upstream. I gave up after sending two reminders
that the issue is still present which resulted in no upstream reaction.
I have been also applying that patch locally for a few months.
Thanks for bringing it up to upstream attention again.

Apologies for us dropping the ball here. There were objections to the
code from Ville [1] but nobody stepped up to clean it up. I think this
was really more about the commit being fixed c64a9a7c05be ("drm/i915:
Update memory bandwidth formulae") than about the patch at hand.
In any case, I've gone ahead and pushed this patch to drm-intel-next
now. With the Fixes tag it should eventually find its way to stable
v5.17+. Thank you for the patch, review - and nagging. ;)
What still remains is cleaning up the code. But that should never have
stalled the fix for months. Sorry again.
BR,
Jani.

Apologies for us dropping the ball here. There were objections to the
code from Ville [1] but nobody stepped up to clean it up. I think this
was really more about the commit being fixed c64a9a7c05be ("drm/i915:
Update memory bandwidth formulae") than about the patch at hand.
In any case, I've gone ahead and pushed this patch to drm-intel-next
now. With the Fixes tag it should eventually find its way to stable
v5.17+. Thank you for the patch, review - and nagging. ;)
What still remains is cleaning up the code. But that should never have
stalled the fix for months. Sorry again.
BR,
Jani.

No worries, better late than never :) Thanks for applying the change!
