that's why ;)

also:
https://www.dictionary.com/browse/busted
"broken, fractured, or seriously damaged"

https://www.merriam-webster.com/dictionary/wedged : "shaped like a wedge" ? :)

or perhaps this: https://dictionary.cambridge.org/us/dictionary/english/wedged

"to make something stay in a particular position by using a wedge"

"to put something into a very small or narrow space, so that it cannot move easily"

that's the i915 terminology and meaning that I'm trying to avoid here...

i.e. wedged can be a temporary state like in i915 where we 'wedge' and 'unwedge'
the gpu in so many cases. That flow doesn't fit well with xe scheduler and it is
a complication that is not desired.

So I want a stronger word that makes it really clear that something went wrong
and won't easily transition back.

>  or lost

but not that strong...

it is not entirely lost... we can still open the client, otherwise we would lose
display and also get the guc logs.

If we really want to go lost and avoid the client connection then we could
simply deregister the drm card device for instance...

looks like 'off' without power...

too strong... like lost.
