HW_REGs are (were!) kind of awful. If the file was HW_REG, you had to
look at different fields for type, abs, negate, writemask, swizzle, and
a second file. They also caused annoying problems like immediate sources
being considered scheduling barriers (commit 6148e94e2) and other such
nonsense.

Instead use ARF/FIXED_GRF/MRF for fixed registers in those files.

After a sufficient amount of time has passed since "GRF" was used, we
can rename FIXED_GRF -> GRF, but doing so now would make rebasing awful.

i965/fs: Set stride correctly for immediates in fs_reg(brw_reg).

The fs_reg() constructors for immediates set stride to 0, except for
vector-immediates, which set stride to 1.  This patch makes the fs_reg
constructor that takes a brw_reg do likewise, so that stride is set
correctly for cases such as fs_reg(brw_imm_v(...)).

The generator asserts that this is true (and presumably it's useful in
some optimization passes?) and the VF fs_reg constructors did this (by
virtue of the fact that it doesn't override what init() does).

In the next commit, calling this constructor with brw_imm_* will generate
an IMM file register rather than a HW_REG, making this change necessary
to avoid breakage with existing uses of brw_imm_v().

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.

glsl: Add precision information to ir_variable

We will need this later on when we implement proper support for
precision qualifiers in the drivers and also to do link time checks for
uniforms as indicated by the spec.

This patch also adds compile-time checks for variables without precision
information (currently, Mesa only checks that a default precision is set
for floats in fragment shaders).

As indicated by Ian, the addition of the precision information to
ir_variable has been done using a bitfield and pahole to identify an
available hole so that memory requirements for ir_variable stay the
same.

v2 (Ian):
  - Avoid if-ladders by defining arrays of supported sampler names and
    indexing
    into them with type->sampler_array + 2 * type->sampler_shadow
  - Make the code that selects the precision qualifier to use an utility
    function
  - Fix a typo

v3 (Tapani):
  - rebased
  - squashed in "Precision qualifiers are not allowed on structs"
  - fixed select_gles_precision for sampler arrays
  - fixed precision_qualifier_allowed for arrays of structs

v4 (Tapani):
  - add atomic_uint handling
  - do not allow precision qualifier on images
  (issues reported by Marta)

v5 (Tapani):
  - support precision qualifier on image types

9 years agoglsl: Add user-defined default precision qualifiers to the symbol table

glsl: Add user-defined default precision qualifiers to the symbol table

Notice that the spec requires that a default precision has been set for every
type used by a shader that can use a precision qualifier and does not have a
predefined precision, however, at the moment, Mesa only checks this for floats
in the fragment shader. This is probably because the GLSL ES 1.0 specs mentions
this case specifically, but GLSL ES 3.0 clarifies that the same applies to
other types:

"The fragment language has no default precision qualifier for floating point
 types. Hence for float, floating point vector and matrix variable
 declarations, either the declaration must include a precision qualifier or
 the default float precision must have been previously declared. Similarly,
 there is no default precision qualifier for the following sampler types in
 either the vertex or fragment language:

 sampler3D;
 samplerCubeShadow;
 sampler2DShadow;
 sampler2DArray;
 sampler2DArrayShadow;
 isampler2D;
 isampler3D;
 isamplerCube;
 isampler2DArray;

 usampler3D;
