Comment suggests it's a remapping thing, and I've seen some idr allocator
thing in vmwgfx before, i.e. it allocates remapping ids for bo, instead of
remapping space. So I think this is all ok, and no need for the TODO here.
With that:

Yeah and exactly because of this I think that allocating a TT structure
doesn't make much sense.
Why should I need an pages array and backing page if I just want to
allocate a number from an idr?
My best guess is that we don't leak memory and because of this nobody
has ever noticed this.

Hm yeah, I guess that's a question for vmwgfx folks to answer then. Feel
free to leave the todo in there.

Hm what's the motivation here? I do agree that the init_mem_type callback
is rather midlayer-y (having a per-type cast in a callback is a very clear
signal something with the layering is all busted). So removing this sounds
like a good idea, but not really following why just for radeon? Or simply
wip?

Crap I missed that. Problem is that I wanted to remove the possibility
to init the system domain with different caching attributes.
I don't see how vmwgfx is every going to use this? Thomas do you have
any idea what this was good for?

I interpret that like vmwgfx can't handle any other caching attribute
than 'cached'. But I can't see anyone feeding vmwgfx system memory
buffers with other caching attributes. In that case, those would be
ignored.

On the first try only the first 3 mails made it to the list and then my
internet connection crashed.
I've send out the full set a minute later once more.

There's little use in copying to zero.

Maybe rather pass old_man->use_tt directly and leave a comment why that
makes sense.

* [PATCH 2/9] drm/ttm: remove TTM_MEMTYPE_FLAG_FIXED
2020-07-23 15:17 More TTM cleanups Christian König

From: Christian König @ 2020-07-23 15:17 UTC (permalink / raw)
To: dri-devel
Instead use a boolean field in the memory manager structure.
Also invert the meaning of the field since the use of a TT
structure is the special case here.
