This comment does not seem accurate, given that DG1 is barely out, and
ADL is not out yet. How about:
"Disabling GuC on untested platforms"?
Just because something is not in the shops yet does not mean it is new.
Technology is always obsolete by the time it goes on sale.
That is a very good reason to not use terminology like "new", "old",
"current", "modern" etc. at all.
End users like me definitely do not share your interpretation of "old".
Yep, old and new is relative. In the end, what matters is the validation
effort, which is why I was proposing "untested platforms".
Also, remember that you are not writing these messages for Intel
engineers, but instead are writing for Linux *users*.
It's drm_dbg. Users don't read this stuff, at least not users with no
clue what the driver does and stuff like that.
If I had a problem, I would read it, and I have no clue what anything
of that is.
Exactly.
This level of defense for what is clearly a bad *debug* message (at the
very least, the grammar) makes no sense at all!
I don't want to hear arguments like "Not my patch" from a developer
literally sending the patch to the ML and who added his SoB to the
patch, playing with words, or minimizing the problem of having such a
message.
All of the above are just clear signals for the community to get off
your playground, which is frankly unacceptable. Your email address does
not matter.
In the spirit of collaboration, your response should have been "Good
catch, how about XXXX or YYYY?". This would not have wasted everyone's
time in an attempt to just have it your way.
My level of confidence in this GuC transition was already low, but you
guys are working hard to shoot yourself in the foot. Trust should be earned!
