We don't have (yet?) inclusive terminology guidelines,
but the PCI hole memory is not "black", the DMA sources
don't stream to "slaves", and there isn't really a TSX
"black" list, we only check for broken fields.
As this terms can be considered offensive, and changing
them is a no-brain operation, simply do it.

Looking at commit 40e80ee4113, the term "broken" seems to be a good
replacement here.

A black hole is a well-known astronomical term, which is simply named
that way since it absorbes all light. I doubt that anybody could get
upset by this term?

Let's put some light in our address space then :)
But you right, the NASA does not consider renaming this one:
https://www.space.com/nasa-stops-racist-nicknames-cosmic-objects.html
Note than for electronic busses design, master/slave are also
well-known terms, but they might be considered offensive.
I changed this one too because I'm not sure about its offensiveness
threshold.

These changes are technically trivial but they are not from an ethical
point of view. I will add to the trivial branch only if they are acked
by their own maintainers.
Moreover, I think we should have a project level guideline before doing
that to be sure everyone agrees.

Agreed. This is a memory region that absorbs all writes and always
reads as zero, the astronomical reference is obvious.

In this particular case I think the change is the right thing to do
simply because the astronomical analogy is not adding any value in
understanding. Calling it a "memoryhole" is more descriptive in what
is actually is.

Absolutely not. A memory hole ("memoryhole" is not an English word)
would be easily confused with a hole in the memory map, which this is
not. For example on x86 systems the "PCI hole" is a hole between the
end of low RAM and the bottom of the ROM that is reserved for memory
mapped devices. The "PCI hole" is explicitly left free by board code so
that the OS can put PCI BARs in there.
These black hole MemoryRegions, instead, are present in the memory map
and their purpose is to absorbs all writes and only sends back zeros,
hiding the contents of SMRAM and TSEG from the guest. Just like a black
hole they are "something that exists".
Therefore, both "memory hole" and "hole" as in Philippe's patch are
worse than the astronomical metaphor.

From Edgar Iglesias:
Regarding streams, our stream module can be used to model a stream
channel such as AXI stream but also other similar stream protocols. We
actually don't use the AXI stream terminology [in hw/core/stream.c].
E.g, we use buf instead of DATA, EOP (end-of-packet) instead of LAST and
have a flow-control mechanism that doesn't refer to valid/ready. IMO,
since we're not matching specific protocol names, it would be fine to
switch to generic terms like Source and Sink.
Therefore,

From Edgar Iglesias:
Regarding streams, our stream module can be used to model a stream
channel such as AXI stream but also other similar stream protocols. We
actually don't use the AXI stream terminology [in hw/core/stream.c].
E.g, we use buf instead of DATA, EOP (end-of-packet) instead of LAST and
have a flow-control mechanism that doesn't refer to valid/ready. IMO,
since we're not matching specific protocol names, it would be fine to
switch to generic terms like Source and Sink.
Therefore,
