[Intel-gfx] [RFC 0/6] 3 display pipes combination system support

[Intel-gfx] [RFC 0/6] 3 display pipes combination system support

[Anshuman Gupta]

This is a proposed RFC solution for 3 display pipes combination
system support.

Anshuman Gupta (6):
  drm/i915: Iterate over pipe and skip the disabled one
  drm/i915: Remove (pipe == crtc->index) asummption
  drm/i915: Fix wrongly populated plane possible_crtcs bit mask
  drm/i915: Get right max plane stride
  drm/i915: Add WARN_ON in intel_get_crtc_for_pipe()
  drm/i915: Enable 3 display pipes support

[Intel-gfx] [RFC 1/6] drm/i915: Iterate over pipe and skip the disabled one

[Anshuman Gupta]

It should not be assumed that a disabled display pipe will be
always last the pipe.
for_each_pipe() should iterate over I915_MAX_PIPES and check
for the disabled pipe and skip that pipe so that it should not
initialize the intel crtc for any disabled pipes.

Few compilation error needed to handle accordingly due to
change in for_each_pipe() macro.

Originally I was envisioning using for_each_set_bit() from bitops.h for
this. It's probably more efficient, however I'm not sure if efficiency
matters much here. The ugly part is that for_each_set_bit() requires an
explicit cast to unsigned long *.

Perhaps this is just as well, it's not wrong, and can always be updated
later.

Are the brace changes really needed? This is what the for_each_if hack
is supposed to tackle.

It is dangling-else warning at couple of places.

IMHO it was dangling-else compilation, warning that requires braces.
please correct me if i am wrong.

Right, I suppose this is caused by the nesting of the for loops with
if-else.

Perhaps the right course of action is to *not* reuse for_each_pipe() in
for_each_pipe_masked(). Just combine the conditions into one.

This is not caused by for_each_pipe_masked, this is caused by for_each_pipe itself,
if (foo)
	/*for_each_pipe()*/
	for(;;)

[Intel-gfx] [RFC 2/6] drm/i915: Remove (pipe == crtc->index) asummption

[Anshuman Gupta]

we can't have (pipe == crtc->index) assumption in
driver in order to support 3 non-contiguous
display pipe system.

The first and second hunks don't really have anything to do with
each other. Also the WARN_ON() should not be removed until all the
assumptions are fixed.

True there can be other assumptions as well, there are few, i have come to know
drm_handle_vblank(&dev_priv->drm, pipe) in gen8_de_irq_handler()
drm_wait_one_vblank(&dev_priv->drm, pipe) in intel_wait_for_vblank(),
i will fix these assumptions is next update, are there any other similar kind of
assumption on which u can throw some light to look for?
I am not sure how does above WARN_ON helps to know all such kind of 
assumptions, but it make sense to have it with FIXME.
Thanks,
Anshuman Gupta.

In fact it's in all irq handlers.

Good catch. Totally forgot about these.

It doesn't help finding them, what it does is make people realize
that they're running a driver which is known to be broken.

Just remembered another borked thing: trans_offsets[]. Some places use
that to check if the transcoder is present, and we don't take fusing
into account when filling that. Though looks like
intel_display_capture_error_state() is the only place where can
actually do the wrong thing (assuming EDP/DSI transcoders are never
fused off).

[Intel-gfx] [RFC 3/6] drm/i915: Fix wrongly populated plane possible_crtcs bit mask

[Anshuman Gupta]

As a disabled pipe in pipe_mask is not having a valid intel crtc,
driver wrongly populates the possible_crtcs mask while initializing
the plane for a CRTC. Fixing up the plane possible_crtc mask.

I don't undestand what you're trying to do here. Looks totally
pointless.

Rather ugly abuse of possible_crtcs. I would remove the current
possible_crtcs assignments totally, and just do something simple like

for_each_intel_plane() {
	crtc = crtc_for_pipe(plane->pipe);
	plane->possible_crtcs = crtc_mask(&crtc->base);
}

I'd probably just add a small helper for this. Eg.:

intel_get_first_crtc()
{
	return to_intel_crtc(drm_crtc_from_index(0))
}

Sure. Might help catch accidents where the caller does a NULL check and
thus doesn't oops.
