*sometimes* an alias for GL_DRAW_FRAMEBUFFER (getters) and *sometimes*

Ideally this function would use DSA functions and not modify the binding
at all.  However, that would be a much more intrusive change because

i965: Introduce a MOV_INDIRECT opcode.

The geometry and tessellation control shader stages both read from
multiple URB entries (one per vertex).  The thread payload contains
several URB handles which reference these separate memory segments.

In GLSL, these inputs are represented as per-vertex arrays; the
outermost array index selects which vertex's inputs to read.  This
array index does not necessarily need to be constant.

To handle that, we need to use indirect addressing on GRFs to select
which of the thread payload registers has the appropriate URB handle.
(This is before we can even think about applying the pull model!)

This patch introduces a new opcode which performs a MOV from a
source using VxH indirect addressing (which allows each of the 8
SIMD channels to select distinct data.)

tested by Pierre Moreau and myself with some compute kernels. This is a
step towards OpenCL.

fragment programs when binding compute programs and vice versa.

nir: Allow outputs reads and add the relevant intrinsics.

variables for outputs, buffering the results and writing them all out
at the end of the program.  However, this is infeasible for tessellation
control shader outputs.

Tessellation control shaders can generate multiple output vertices, and
write per-vertex outputs.  These are arrays indexed by the vertex
number; each thread only writes one element, but can read any other
element - including those being concurrently written by other threads.
The barrier() intrinsic synchronizes between threads.

Even if we tried to shadow every output element (which is of dubious
value), we'd have to read updated values in at barrier() time, which
means we need to allow output reads.

Most stages should continue using nir_lower_outputs_to_temporaries(),

9 years agoegl/wayland: Ignore rects from SwapBuffersWithDamage
Daniel Stone [Sat, 7 Nov 2015 18:25:31 +0000 (18:25 +0000)]
egl/wayland: Ignore rects from SwapBuffersWithDamage

eglSwapBuffersWithDamage accepts damage-region rectangles to hint the
compositor that it only needs to redraw certain areas, which was passed
through the wl_surface_damage request, as designed.

Wayland also offers a buffer transformation interface, e.g. to allow
users to render pre-rotated buffers. Unfortunately, there is no way to
query buffer transforms, and the damage region was provided in surface,
rather than buffer, co-ordinate space.

Users could in theory account for this themselves, but EGL also requires
co-ordinates to be passed in GL/mathematical co-ordinate space, with an
inversion to Wayland's natural/scanout co-ordinate space, so
transformations other than a 180-degree rotation will fail as EGL
attempts to subtract the region from (its view of the) surface height.

Pending creation and acceptance of a wl_surface.buffer_damage request,
which will accept co-ordinates in buffer co-ordinate space, pessimise to
always sending full-surface damage.

bce64c6c provides the explanation for why we send maximum-range damage,
rather than the full size of the surface: in the presence of buffer
transformations, full-surface damage may not actually cover the entire
surface.
