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.

  - Make the code that selects the precision qualifier to use an utility

  - Fix a typo

i965: Split nir_emit_intrinsic by stage with a general fallback.

Many intrinsics only apply to a particular stage (such as discard).
In other cases, we may want to interpret them differently based on
the stage (such as load_primitive_id or load_input).

The current method isn't that pretty - we handle all intrinsics in
one giant function.  Sometimes we assert on stage, sometimes we forget.
Different behaviors are handled via if-ladders based on stage.

This commit introduces new nir_emit_<stage>_intrinsic() functions,
and makes nir_emit_instr() call those.  In turn, those fall back to
the generic nir_emit_intrinsic() function for cases they don't want
to handle specially.

This makes it clear which intrinsics only exist in one stage, and makes
it easy to handle inputs/outputs differently for various stages.

i965/nir/opt_peephole_ffma: Bypass fusion if any operand of fadd and fmul is a const

When both fadd and fmul instructions have at least one operand that is a
constant and it is only used once, the total number of instructions can
be reduced from 3 (1 ffma + 2 load_const) to 2 (1 fmul + 1 fadd); because
the constants will be progagated as immediate operands of fmul and fadd.

This patch detects these situations and prevents fusing fmul+fadd into ffma.

Shader-db results on i965 Haswell:

total instructions in shared programs: 6235835 -> 6225895 (-0.16%)

9 years agoglsl: Use array deref for access to vector components

glsl: Use array deref for access to vector components

We've assumed that we could lower per-component vector access from

  vec[i] = scalar

to

  vec = ir_triop_vector_insert(vec, scalar, i)

but with SSBOs (and compute shader SLM and tesselation outputs) this is
no longer valid. If a vector is "externally visible", multiple threads
can write independent components simultaneously. With lowering to
ir_triop_vector_insert, each thread read the entire vector, changes one
component, then writes out the entire vector. This is racy.

Instead of generating a ir_binop_vector_extract when we see v[i], we
generate ir_dereference_array. We then add a lowering pass to lower the
ir_dereference_array to ir_binop_vector_extract for rvalues and for to
vector_insert for lvalues in a separate lowering pass.

The resulting IR is the same as before, but we now have a window between
ast->ir conversion and the lowering pass where v[i] appears in the IR as
an array deref. This lets us run lowering passes that lower the vector
access to I/O (eg for SSBO load/store) before we lower the per-component
access to full vector writes.
