[PATCH 0/7] hw/misc/empty_slot: Spring cleaning
Posted by Philippe Mathieu-Daudé 3 years, 12 months ago 
New Spring, new opportunity to clean this device :)
(v1 was in 2018, v2 in 2019).

- lower device priority
- follow qdev model and use properties
- convert to trace events
- describe with slot name
- move under hw/misc/ and cover in MAINTAINERS

Peter, I hope you are OK adding it wit UNIMP device,
as both are very similar, and don't have much activity.

Only MIPS/SPARC32 targets use this device.

v2: https://www.mail-archive.com/qemu-devel@nongnu.org/msg626498.html
v1: https://www.mail-archive.com/qemu-devel@nongnu.org/msg564060.html

I agree with all of your patches, they absolutely make sense to me,
but I would like to know Peter's opinion on such treatment of empty
slots.

I am going to give r-bs and integrate mips patches as soon as Peter
OKs the general approach. So, Peter, is Philippe's approach to empty
slots fine?

Thanks Aleksandar for looking at this series.

I expect a neutral opinion from Peter.

What would be helpful is feedback from Artyom, since it authored this
device.

Artyom, do you mind Acking the series?

Thanks,

Phil.

Yes. In particular I cannot be the bottleneck for all design
choices in QEMU: that doesn't scale. Mostly you can assume
that if I have a strong opinion then I'll provide it, and
otherwise I prefer it if the people who care enough to
maintain code and write patches to tidy it up make the choices.

(Empty slots seemed a bit odd to me last time I looked at them,
but if they work for mips and sparc that's fine with me.)

thanks

Thanks for asking and sorry for the delay. My mailer played a bad trick on me.
The patches definitely make sense:

Thanks - except the MAINTAINERS change (merging empty_slot with
unimp device) which Peter did not ack - series applied to for
the next (temporary) sparc-next pull request.
