Oh I can drop those. I had plans to expose some sysfs stuff, but I
don't think I'll bother. Thanks.

To: dri-devel; +Cc: intel-gfx, rob.clark
To properly support the various plane formats supported by different
hardware, the kernel must know the pixel format of a framebuffer object.
So add a new ioctl taking a format argument corresponding to a fourcc
name from videodev2.h.

To: dri-devel; +Cc: intel-gfx, rob.clark

handle scaling as well. So add support for them using the new DRM core
sprite support functions.

SNB register block and it's usage looks good.

That XBRG is a bit misleading, because the X here means extended range as
opposed to the usual gl meaning of unused. It sounds like a format with
shared exponent, gl seems to use E for that, i.e E2BGR101010.

Gamma regs are a bit funky, especially on SNB. I assume you'll add all the
necessary defines when set_gamma support shows up.

Actually, this is wrong. Before the fb gets destroyed we call
drm_framebuffer_cleanup which takes care of this problem. The fact that
- currently drivers call this instead of the drm core
- it's a ducttape solution instead of refcounting
doesn't really make it nice, but it works.
Aside: The insane refcoungting dance in page_flip because the drm core
doesn't know that we still need the to-be-flipped-out fb, it forgets about
it right away. Maybe that's the reason for the above confusion.

Is that required or just paranoia? I haven't found anything in bspec

Ok, how does this tie in with dpms handling? This here feels like a major
cludge ... I suspect we want a dpms function on the plane that gets called
by the common dpms helper before switching of the crtc and after switching
it on. Or at least some driver-hack like I've done for the overlay.

Allowing the crtc dest rect to extend beyond that of the crtc and then refusing to
properly adjust tiling is a bit inconsistent. I call design-by-committee
on this one ;-)
If the goal is that this plane stuff is somewhat generically useable, I
think this needs to be fixed. If the goal is simply to keep the bubble
intact, I don't mind this as-is, because I don't care ;-)

Afaics the hw supports untiled buffers (you need to frob the linear offset
register instead of the x/y register for tiled surfaces). Does that not
work?

Passing obj instead of start would also make untiled sprite easier ...

Minor locking nitpick: You only need to hold around pin and unpin, not
over the vblank. Stopping gem for 20 msec just to show a sprite is not so
great. I know, our locking isn't really great in general and there are
many other places where we stall in similarly bad ways, still ...

Again, move the vblank_wait which is inside the disable_plane outside of
the struct_mutex lock. We really need some generic infrastructure to run
something after the next vblank in a workqueu. Would clean up pageflip,
the legacy overlay and kill the vblank here ...

Oops, that comment went fubar while transferring from brainwaves to bits.
Instead of "adjust tiling" it should be "adjust the source rectangle to
the restricted crtc dest".

Ah I see, yeah there are 2 30 bit formats, one with XR bias... I
should probably drop that since we don't know the actual bit layout.

Yeah we may need some new ioctls to control the different colorspace
correction and gamma stuff the latest hw supports. I think we can
correct at various places in the pipeline as well...

That would be a bit invasive... and may not be what every driver
wants. Does it belong in set_config? Or do we just forcibly disable
the planes everywhere?

Not sure I understand what you mean about drm_framebuffer_cleanup
taking care of the problem. The refcounting and fb handling may not be
ideal, but taking refs on the underlying objects is what we need to do
today.
I don't want to change that as part of this series, but did want to
explain why we take a private ref for the plane object here.

The scaling disable was just to avoid surprises (in fact now that I look
I need to mask it off in the update function).
The surf write is definitely needed, since it triggers the double
buffered reg update.

The primary goal here is to keep the plane from breaking if a crtc rect
that includes an offscreen portion is passed in.
Moving the source rect would involve potential scaling. I can do that,
but was trying to avoid it. We can also change it when we see what the
embedded folks had in mind (I think Rob was the one who wanted signed
crtc position to make some things easy).

Yes it does, and I see the regs on IVB now. I'll implement support for
them to make it easier to display surfaces from misc. sources without
copying.

Yeah, that would be nice. Blocking userspace on the vblank is also not
nice.

Slavish emulation of some other teardown code paths. If we ever do
flipping on the sprites, I think we'll want it.

Core drm code currently does not call fb_helper_restore, that's the
drivers job atm (yeah, somewhere on my todo). And i915 is currently the
only one with sprite support. And I don't think we want the last video
frame to occlude the OOPS when X died. So yes, this imo belongs into the
fb_helper.

Well, I think we don't need to take refs. set_base gets away with it, too:
- the pin/unpin ensures that the buffer doesn't move.
- the drm core holds onto both the old and the new fb for the duration of
the update_plane, so we also have a reference on that. And that
reference won't disappear without a disable_plane thanks to the addition to

Yeah, cleanup up our fb handling will be a bit messy.

Ok, missed that in bspec review. Maybe add a comment for dummies
somewhere?

I think when we do flipping on sprites, we should try MI_LOAD_REG to latch
the double-buffered regs in the command stream. That way it'd work like
the pageflip paths.

Add new ioctls for getting and setting the current destination color
key. This allows for simple overlay display control by matching a color
key value in the primary plane before blending the overlay on top.

A few comments below and a snide-y one here: If the goal is simply to keep
the bubble intact, this is fine by me. If we want something that has the
chance to be useable by a generic driver I think we want a drm interface
for plane/crtc properties (you could wire up set_gamma on planes in the
same series ... ;-) Again, I don't really care ...
Cheers, Daniel

"Just grab the lock in case" is nice and all, but totally unnecessary
here. You already grab the mode_config.mutex in the intel ioctl interface
function.

Frankly I'd prefer the driver code to simply keep track of the destkey
instead of interogating the hw with the ->get_destkey call.

Even further off topic, the panel scaler support should ideally be a
property of crtcs/planes rather than a connector property. However,
that would be a bit of pain to implement and keep backwards
compatibility.

I think we could just internally route the output pannel-fitter prop to
the crtc one. After all if the hw has the fitter really on the crtc,
moving it also logically to the crtc won't make anything previously
possibel impossible ...

I'm ok with having generic properties for these. But I don't want to
go through the same 8 month process of getting buy-in from other
chipsets and people before the code is pushed as I've done with the
core DRM bits.
And since I know nothing of the color key support details for other
chipsets, I've simply made this one device specific. We'll have more
in the future too; current hardware can do source keying, and future
hardware will be able to blend 3 planes per pipe together using alpha
blending.
If some other hardware has similar features and someone steps up to do
the code, I'd be happy to work with them to get some generic interfaces
in. In the meantime though, I'd like to see some i915 interfaces so we
can actually use this stuff before the world ends in 2012.

To save power when the sprite is full screen, we can disable the primary
plane on the same pipe. Track the sprite status and enable/disable the
primary opportunistically.

Planes are a bit like half-CRTCs. They have a location and fb, but
don't drive outputs directly. Add support for handling them to the core
KMS code.

Accidentally left out the ->destroy hook in this one. The drm-overlays
branch at git://people.freedesktop.org/~jbarnes/linux has a fixed
version, along with a couple of fixes for issues Chris and Dan pointed
out.

Below is the updated patch with ->destroy in case this series passes
muster and Dave is ready to apply.

Subject: [PATCH 1/4] drm: add plane support
Planes are a bit like half-CRTCs. They have a location and fb, but
don't drive outputs directly. Add support for handling them to the core
KMS code.

...and now fixed to include a disable call if an active fb is destroyed
while being used in a plane.

Subject: [PATCH 1/5] drm: add plane support
Planes are a bit like half-CRTCs. They have a location and fb, but
don't drive outputs directly. Add support for handling them to the core
KMS code.

Ok, with the drm_framebuffer_cleanup fixed up, this looks code. I've also
played around a bit with the legacy i8xx overlay, and the existing code
would nicely fit into ->update_plane and ->disable_plane.

Where are crtc and fb of struct drm_plane assigned?
First, i did it in device specific update_plane, but can do in
drm_mode_setplane?
