For example: gl_FbWposYTransform. This is introduced as part of
nir_lower_wpos_ytransform. On GLSL that is executed after the IR-based

SPIR-V has both VertexIndex and VertexId builtins whose meanings are
defined by the APIs.

Vulkan defines VertexIndex as being non-zero-based. In Vulkan VertexId
and InstanceId have no meaning and are pretty much just reserved for
OpenGL at this point.

GL_ARB_spirv removes VertexIndex and defines VertexId to be the same
as gl_VertexId (which is also non-zero-based).

Previously in Mesa it was treating VertexIndex as non-zero-based and
VertexId as zero-based, so it was breaking for GL. This behaviour was
apparently based on Khronos bug 14255. However that bug doesn’t seem
to have made a final decision for VertexId.

both formats.  If both are Z24X8, we continue using B8G8R8A8_UNORM to

python: Rework bytes/unicode string handling

In both Python 2 and 3, opening a file without specifying the mode will

On Python 2, the read() method of a file object opened in mode 'r' will
return byte strings, while on Python 3 it will return unicode strings.

Explicitly specifying the binary mode ('rb') then decoding the byte
string means we always handle unicode strings on both Python 2 and 3.

Which in turns means all re.match(line) will return unicode strings as
well.

If we also make expandCString return unicode strings, we don't need the
call to the unicode() constructor any more.

We were using the ugettext() method because it always returns unicode

byte strings. The ugettext() method doesn't exist on Python 3, so we
must use the right method on each version of Python.

The last hurdles are that Python 3 doesn't let us concatenate unicode
and byte strings directly, and that Python 2's stdout wants encoded byte
strings while Python 3's want unicode strings.

Python 2.4 introduced key-functions, which instead only operate on a
given item, and return a sorting key for this item.

In general, this runs faster, because the cmp-function has to get run

intel: Fix SIMD16 unaligned payload GRF reads on Gen4-5.

When the SIMD16 Gen4-5 fragment shader payload contains source depth
(g2-3), destination stencil (g4), and destination depth (g5-6), the
single register of stencil makes the destination depth unaligned.

We were generating this instruction in the RT write payload setup:

   mov(16)   m14<1>F   g5<8,8,1>F   { align1 compr };

which is illegal, instructions with a source region spanning more than
one register need to be aligned to even registers.  This is because the
hardware implicitly does (nr | 1) instead of (nr + 1) when splitting the
compressed instruction into two mov(8)'s.

I believe this would cause the hardware to load g5 twice, replicating
subspan 0-1's destination depth to subspan 2-3.  This showed up as 2x2
artifact blocks in both TIS-100 and Reicast.

Normally, we rely on the register allocator to even-align our virtual
GRFs.  But we don't control the payload, so we need to lower SIMD widths
to make it work.  To fix this, we teach lower_simd_width about the
restriction, and then call it again after lower_load_payload (which is
what generates the offending MOV).

6 years agowayland/egl: update surface size on window resize
Juan A. Suarez Romero [Wed, 6 Jun 2018 10:13:05 +0000 (10:13 +0000)]
wayland/egl: update surface size on window resize

According to EGL 1.5 spec, section 3.10.1.1 ("Native Window Resizing"):

  "If the native window corresponding to _surface_ has been resized
   prior to the swap, _surface_ must be resized to match. _surface_ will
   normally be resized by the EGL implementation at the time the native
   window is resized. If the implementation cannot do this transparently
   to the client, then *eglSwapBuffers* must detect the change and
   resize surface prior to copying its pixels to the native window."

So far, resizing a native window in Wayland/EGL was interpreted in Mesa
as a request to resize, which is not executed until the first draw call.
And hence, surface size is not updated until executing it. Thus,
querying the surface size with eglQuerySurface() after a window resize
still returns the old values.

This commit updates the surface size values as soon as the resize is
done, even when the real resize is done in the draw call. This makes the
semantics that any native window resize request take effect inmediately,
and if user calls eglQuerySurface() it will return the new resized
values.

invalid until buffers are updated (like calling glClear()).

But according to EGL 1.5 spec, section 3.5.6 ("Surface Attributes"):

  "Querying EGL_WIDTH and EGL_HEIGHT returns respectively the width and

   these values are initially equal to the width and height of the

* eglQueryContext(EGL_RENDER_BUFFER)

  The implementation of this suffered from the same issues as
  eglQuerySurface, and the solution is the same.  confidence in its
  correctness, flatten its indirect logic. For pixmap and pbuffer
  surfaces, simply return a hard-coded literal value, as the spec
  suggests. For window surfaces, simply return
  _EGLSurface::ActiveRenderBuffer.
