As I told people in [1] we really should not be confusing enum plane
as a per-pipe plane identifier. Looks like that happened nonetheless, so
let's fix it up by splitting the two into two enums.
We'll also want something we just directly pass to various register
offset macros and whatnot on SKL+. So let's make this new thing work for that.
Currently we pass intel_plane->plane for the "sprites" and just a
hardcoded zero for the "primary" planes. We want to get rid of that
hardocoding so that we can share the same code for all planes (apart
from the legacy cursor of course).

Add a mask of which planes are available for each pipe. This doesn't
quite work for old platforms with dynamic plane<->pipe assignment, but
as we don't support that sort of stuff (yet) we can get away with it.
The main use I have for this is the for_each_plane_id_on_crtc() macro
for iterating over all possible planes on the crtc. I suppose we could
not add the mask, and instead iterate by comparing intel_plane->pipe
but then we'd need a local intel_plane variable which is just
unnecessary clutter in some cases. But I'm not hung up on this, so if
people prefer the other option I could be convinced to use it.
v2: Use BIT() in the iterator macro too (Paulo)

Nuke skl_wm_plane_id() and just use the new intel_plane->id.
v2: Convert skl_write_plane_wm() as well
v3: Convert skl_pipe_wm_get_hw_state() correctly
v4: Rebase due to changes in the wm code
Drop the cursor FIXME from the total data rate calc (Paulo)
Use the "[PLANE:%d:%s]" format in debug print (Paulo)

Replace the intel_plane->plane and hardcoded 0 usage in the SKL plane
code with intel_plane->id.
This should make the SKL "primary" and "sprite" code virtually
identical, so the next logical step would likely be dropping one
of the copies.

Use intel_plane->id to derive the VLV/CHV sprite register offsets
instead of abusing plane->plane which is really meant to for
primary planes only.
v2: Convert assert_sprites_disabled() over as well
v3: Rename the reg macro parameter to 'plane_id' as well (Paulo)

Let's try not to abuse plane->plane for sprites on VLV/CHV and instead
use plane->id. Since out watermark structures aren't entirely plane type
agnostic (for now) and start indexing sprites from 0 we'll add a small
helper to convert between the two bases.

Rename the SKL plane register define 'plane' parameter to 'plane_id' to
reflect the fact that you're supposed to pass in the enum plane_id
rather than enum plane.
Do the same for the scaler plane selector bits.

With plane->plane now purely reserved for the primary planes, let's
not even populate it for cursors and sprites. Let's switch the type
to enum plane as well since it's no longer being abused for anything
else.

Since it's a primary plane thing, I think it makes more sense to just
leave it at struct intel_crtc instead of having a field that's unused
and doesn't make sense in some cases. The crtc struct already includes
some fields that are specific to primary planes, so I think it's a good
place. Or we could create a new class: struct intel_primary_plane {
struct intel_plane base; enum plane legacy_plane };
Following is a patch suggestion (probably impossible to apply due to my
editor breaking long lines). Any arguments against it?

Primary plane aren't really primary planes on old platforms though.
That's just a software concept that has no bearing on the hardware.

Please explain more since that's not my understanding. I just opened
the gen 2 and 3 spec docs and they do contain tons of "primary plane"
references. I know that the hardware is a little more flexible there,
but as far as I understand we don't even implement that. Besides, both
our driver and our API do have the concept of a primary plane, so it
makes sense for the code to be organized that way, IMHO. Besides, I
think our code organizations should always better fit the new hardware,
since otherwise we'll make i915.ko development even harder than it is
for new contributors/employees.
(And when I see those specs and realize how different the HW was, then
I remember that in order to explain to the new people why some things
are the way they are in our code I have to explain how the HW was 10
years ago, I start thinking again that maybe we should just have i915-
old.ko and i915-new.ko, since either we make our abstractions/design
fit one thing or we make it fit another...)

Not at the moment. But I have plans...

A plane is a plane, a pipe is a pipe. IMO you're trying to make it
more confusing by mixing up the two.

If you don't mix planes and pipes there can't be any confusion.

From the register POV hw was almost identical up to BDW at least. It's
just a few bits (the pipe selector) that vanished from the registers.
SKL+ is a little more different but still the registers even live in the
same address.
Also given what recent history has shown us, I wouldn't be at all
surprised if we would go back to a flexible plane<->pipe assignment
in the hardware at some point in the future. A lot of the other
features that were present in old hardware has been making a comeback
in recent years.

I think that goes against your original argument to remove the plane-
>plane assignment for everything except for primary planes.
Anyway, your argumentation is very short and dismissive, it's hard to
understand what exactly you are thinking and try to move the discussion
forward.
I suppose we'll just have to agree to disagree here. In one solution we
create an inconsistency where the plane struct has a field that's only
applicable and can only be used to some specific planes (even though
"every plane is a plane"). In the other solution we create the
inconsistency where the crtc<->plane connection is assigned in the way
not chosen by the hardware and this may be a problem if we ever get to
implement the plane assignment flexibility that's allowed by the
hardware. Maybe having a 3rd opinion here would help.

I find the two plane fields in struct intel_plane a bit confusing, but I don't
think the right solution is to leave that in intel_crtc. If I understand
correctly, we have a problem of uniquely identifying a plane, since that takes
different forms in different platforms. Neither of the generically named enums,
enum plane and enum plane_id, is sufficiently generic.
Would it make sense to turn things up-side down? Now we are trying to make a
crtc be able to find the proper registers for a plane. Instead we could just not
do it and define everything in terms of functions that take planes. Then we
could hide the details of mapping some bit of information in intel_plane to the
appropriate registers in platform-dependent vfuncs. And perhaps give those enums
a platform-dependent name, i.e., enum i8xx_plane_id, enum skl_plane_id, etc.
Anyway, I haven't looked much into it, so just ignore me if I'm way off.

I'm not even sure where to find bspecs for the really old
platforms...how flexible were those primary planes? Can we drive both
"primary" planes at the same time on a single CRTC if we're not using
the second pipe? If not, is there some other benefit we get from not
enforcing a fixed pipe-plane association?

There are three "primary" planes, two cursors, and one video overlay.
Any one can be assigned to either pipe more or less freely (some
restrctions do apply). The planes aren't uniform (not even the
"primary" planes) and instead have different capabilities between them.

Now we've rename the local plane id variable as 'plane_id' everywhere
except the pre-SKL primary plane code. Let's do the rename there as well
so that we'll free up the name 'plane' for use with struct intel_plane*.
