Kenneth Graunke [Fri, 6 Sep 2013 23:59:31 +0000 (16:59 -0700)]
i965: Implement glDrawTransformFeedback().

Implementing the GetTransformFeedbackVertexCount() driver hook allows
the VBO module to call us with the right number of vertices.

The hardware doesn't directly count the number of vertices written by
SOL, so we instead use the SO_NUM_PRIMS_WRITTEN(n) counters and multiply
by the number of vertices per primitive.

Unfortunately, counting the number of primitives generated is tricky:
a program might pause a transform feedback operation, start a second one
with a different object, then switch back and resume.  Both transform
feedback operations share the SO_NUM_PRIMS_WRITTEN counters.

To work around this, we save the counter values at Begin, Pause, Resume,
and End.  This "bookends" each section where transform feedback is
active for the current object.  Adding up differences of pairs gives
us the number of primitives generated.  (This is similar to what we
do for occlusion queries on platforms without hardware contexts.)

v2: Fix missing parenthesis in assertion (caught by Eric Anholt).
v3: Reuse prim_count_bo rather than freeing it and immediately
    allocating a new one (suggested by Topi Pohjolainen).

10 years agomesa: Add a new GetTransformFeedbackVertexCount() driver hook.
Kenneth Graunke [Mon, 27 May 2013 18:27:18 +0000 (11:27 -0700)]
mesa: Add a new GetTransformFeedbackVertexCount() driver hook.

DrawTransformFeedback() needs to obtain the number of vertices written
to a particular stream during the last Begin/EndTransformFeedback block.
The new driver hook returns exactly that information.

Gallium drivers already implement this by passing the transform feedback
object to the drawing function, counting the number of vertices written
on the GPU, and using draw indirect.  This is efficient, but doesn't
always work:

If vertex data comes from user arrays, then the VBO module needs to
know how many vertices to upload, so we need to synchronously count.
Gallium drivers are currently broken in this case.

It also doesn't work if primitive restart is done in software.  For
normal drawing, vbo_draw_arrays() performs software primitive restart,
splitting the draw call in two.  vbo_draw_transform_feedback() currently
doesn't because it has no idea how many vertices need to be drawn.

The new driver hook gives it that information, allowing us to reuse
the existing vbo_draw_arrays() code to do everything right.

On Intel hardware (at least Ivybridge), using the draw indirect approach
is difficult since the hardware counts primitives, rather than vertices,
which requires doing some simple math.  So we always use this hook.

Gallium drivers will likely want to use this hook in some cases, but
want to use the existing draw indirect approach where possible.  Hence,
I've added a flag to allow drivers to opt-in to this call.

v2: Make it possible to implement this hook but only use this path
    when necessary (suggested by Marek).

i965: Implement Pause/ResumeTransformfeedback driver hooks on Gen7+.

The ARB_transform_feedback2 extension introduces the ability to pause

at a time, it's possible to switch between multiple transform feedback
objects while paused.

In order to facilitate this, we need to save/restore the SO_WRITE_OFFSET
registers so that after resuming, the GPU continues writing where it
left off.

This functionality also exists in ES 3.0, but somehow we completely

llvmpipe: fix bogus layer clamping in setup

The layer coming from GS needs to be clamped (not sure if that's actually
the correct error behavior but we need something) as the number can be higher
than the amount of layers in the fb. However, this code was using the layer
calculation from the scene, and this was actually calculated in
lp_scene_begin_rasterization() hence too late (so setup was using the value
from the _previous_ scene or just zero if it was the first scene).
Since the value is used in both rasterization and setup, move calculation up
to lp_scene_begin_binning() though it's a bit more inconvenient to calculate
there. (Theoretically could move _all_ code which was in
lp_scene_begin_rasterization() to there, because ever since we got rid of
swizzled render/depth buffers our "map" functions preparing the fb data for
render don't actually change the data in there at all, but it feels like
it would be a hack.)
