A common use case for transform feedback is to perform one draw
operation that writes transform feedback output to a buffer, followed
by a second draw operation that consumes that buffer as vertex input.
Since vertex input is consumed at an earlier pipeline stage than
writing transform feedback output, we need to flush the pipeline to
ensure that the transform feedback output is completely written before

Previous to this patch, the function intel_batchbuffer_emit_mi_flush()
was a bit of a misnomer.  On Gen4+, when not using the blit engine, it
didn't actually flush the pipeline--it simply generated a PIPE_CONTROL
command with the necessary bits set to flush GPU caches.  This was
usually sufficient, since in most situations where
intel_batchbuffer_emit_mi_flush() was called, all we really care about
was ensuring cache coherency.

However, with the advent of OpenGL 3.0, there are two cases in which
data output by one stage of the pipeline might be consumed, in a later
draw operation, by an earlier stage of the pipeline:

(a) When using textures in the vertex shader.

(b) When using drawing with a vertex buffer that was previously
    generated using transform feedback.

This patch addresses case (a) by changing
intel_batchbuffer_emit_mi_flush() so that on Gen6+, it sets the
PIPE_CONTROL_CS_STALL bit (this forces the pipeline to actually
flush).  (Case (b) will be addressed by the next patch in the series).

This is not an ideal solution--in a perfect world, the driver would
have some buffer dependency tracking so that we would only have to
flush the pipeline in the two cases above.  Until that dependency
tracking is implemented, however, it seems prudent to have
intel_batchbuffer_emit_mi_flush() actually flush the pipeline, so that
we get correct rendering, at the expense of a (hopefully small)
performance hit.

The change is only applied to Gen6+, since at the moment only Gen6+
supports the OpenGL 3.0 features that make a full pipeline flush
necessary.

i965 gen6: Initial implementation of transform feedback.

This patch adds basic transform feedback capability for Gen6 hardware.
This consists of several related pieces of functionality:

(1) In gen6_sol.c, we set up binding table entries for use by
transform feedback.  We use one binding table entry per transform
feedback varying (this allows us to avoid doing pointer arithmetic in
the shader, since we can set up the binding table entries with the
appropriate offsets and surface pitches to place each varying at the
correct address).

(2) In brw_context.c, we advertise the hardware capabilities, which
are as follows:

   MAX_TRANSFORM_FEEDBACK_INTERLEAVED_COMPONENTS 64
   MAX_TRANSFORM_FEEDBACK_SEPARATE_ATTRIBS        4
   MAX_TRANSFORM_FEEDBACK_SEPARATE_COMPONENTS    16

OpenGL 3.0 requires these values to be at least 64, 4, and 4,
respectively.  The reason we advertise a larger value than required
for MAX_TRANSFORM_FEEDBACK_SEPARATE_COMPONENTS is that we have already
set aside 64 binding table entries, so we might as well make them all
available in both separate attribs and interleaved modes.

(3) We set aside a single SVBI ("streamed vertex buffer index") for
use by transform feedback.  The hardware supports four independent
SVBI's, but we only need one, since vertices are added to all
transform feedback buffers at the same rate.  Note: at the moment this
index is reset to 0 only when the driver is initialized.  It needs to
be reset to 0 whenever BeginTransformFeedback() is called, and
otherwise preserved.

(4) In brw_gs_emit.c and brw_gs.c, we modify the geometry shader
program to output transform feedback data as a side effect.

(5) In gen6_gs_state.c, we configure the geometry shader stage to
handle the SVBI pointer correctly.

Note: ordering of vertices is not yet correct for triangle strips
(alternate triangles are improperly oriented).  This will be addressed
in a future patch.

mesa: Record transform feedback strides/offsets in linker output.

This patch adds two new fields to the gl_transform_feedback_info
struct:

- BufferStride records the total number of components (per vertex)
  that transform feedback is being instructed to store in each buffer.

- Outputs[i].DstOffset records the offset within the interleaved
  structure of each transform feedback output.

These values are needed by the i965 gen6 and r600g back-ends, so it
seems better to have the linker provide them rather than force each
back-end to compute them independently.

Also, DstOffset helps pave the way for supporting
ARB_transform_feedback3, which allows the transform feedback output to
contain holes between attributes by specifying
gl_SkipComponents{1,2,3,4} as the varying name.

Send the DestroyContext protocol immediately when glXDestroyContext is
called, and never call it when glXFreeContextEXT is called.  In both
cases, either destroy the client-side structures or, if the context is
current, set xid to None so that the client-side structures will be
destroyed later.

I believe this restores the behavior of the original SGI code.  See
src/glx/x11 around commit 5df82c8.  The spec doesn't say anything
about glXDestroyContext not really destroying imported contexts (it
acts like glXFreeContextEXT instead), but that's what the original
code did.  Note that glXFreeContextEXT on a non-imported context does
not destroy it either.

Fixes the piglit test glx-free-context.

12 years agoglx: Don't create a shared context if the other context isn't the same kind
Ian Romanick [Tue, 6 Dec 2011 20:19:39 +0000 (12:19 -0800)]
glx: Don't create a shared context if the other context isn't the same kind

Each of the DRI, DRI2, and DRISW backends contain code like the
following in their create-context routine:

   if (shareList) {
      pcp_shared = (struct dri2_context *) shareList;
      shared = pcp_shared->driContext;
   }

This assumes that the glx_context *shareList is actually the correct
derived type.  However, if shareList was created as an
indirect-rendering context, it will not be the expected type.  As a
result, shared will contain garbage.  This garbage will be passed to
the driver, and the driver will probably segfault.  This can be
observed with the following GLX code:

    ctx0 = glXCreateContext(dpy, visinfo, NULL, False);
    ctx1 = glXCreateContext(dpy, visinfo, ctx0, True);

Create-context is the only case where this occurs.  All other cases
where a context is passed to the backend, it is the 'this' pointer
(i.e., we got to the backend by call something from ctx->vtable).

To work around this, check that the shareList->vtable->destroy method
is the same as the destroy method of the expected type.  We could also
check that shareList->vtable matches the vtable or by adding a "tag"
to glx_context to identify the derived type.
