e32e2836a3 nv50: make sure to clear _all_ layers of all attachments
Unfortunately there's only one RT_ARRAY_MODE setting for all

of layers any attachment had. Instead set the RT_ARRAY_MODE to 512 (the

5437d38fac vdpau: flush the context before exporting the surface v2
Bugzilla (bug needs XBMC changes as well):
https://bugs.freedesktop.org/show_bug.cgi?id=73191

When VL uploads vertex buffers, it uses PIPE_TRANSFER_DONTBLOCK, which always
flushes the context in the winsys if the buffer being mapped is busy. Since
I added handling of DISCARD_RANGE, DONTBLOCK has had no effect when combined
with DISCARD_RANGE and I think the context isn't flushed anywhere else,
so no commands are submitted to the GPU until the IB is full, which takes
a lot of frames.

Using DISCARD_RANGE is not the only way to trigger this bug. The other way
is to reallocate the vertex buffer before every upload.

BTW, I'm not sure if this is the right place for flushing, but it does fix
the bug.

v2 (chk): move the flush to the right place.

7cb4dea765 i965: Create a hardware context before initializing state module.
brw_init_state() calls brw_upload_initial_gpu_state().  If hardware
contexts are enabled (brw->hw_ctx != NULL), this will upload some
initial invariant state for the GPU.  Without hardware contexts, we
rely on this state being uploaded via atoms that subscribe to the
BRW_NEW_CONTEXT bit.

Commit 46d3c2bf4d accidentally moved
the call to brw_init_state() before creating a hardware context.
This meant brw_upload_initial_gpu_state would always early return.
Except on Gen6+, we stopped uploading the initial GPU state via
state atoms, so it never happened.

Fixes a regression since 46d3c2bf4d.

b498fb9586 glsl: Only warn for macro names containing __
From page 14 (page 20 of the PDF) of the GLSL 1.10 spec:

    "In addition, all identifiers containing two consecutive underscores
     (__) are reserved as possible future keywords."

The intention is that names containing __ are reserved for internal use
by the implementation, and names prefixed with GL_ are reserved for use
by Khronos.  Names simply containing __ are dangerous to use, but should
be allowed.

Per the Khronos bug mentioned below, a future version of the GLSL
specification will clarify this.

3731a4fae4 glcpp: Only warn for macro names containing __
Section 3.3 (Preprocessor) of the GLSL 1.30 spec (and later) and the
GLSL ES spec (all versions) say:

    "All macro names containing two consecutive underscores ( __ ) are
    reserved for future use as predefined macro names. All macro names
    prefixed with "GL_" ("GL" followed by a single underscore) are also
    reserved."

The intention is that names containing __ are reserved for internal use
by the implementation, and names prefixed with GL_ are reserved for use
by Khronos.  Since every extension adds a name prefixed with GL_ (i.e.,
the name of the extension), that should be an error.  Names simply
containing __ are dangerous to use, but should be allowed.  In similar
cases, the C++ preprocessor specification says, "no diagnostic is
required."

Per the Khronos bug mentioned below, a future version of the GLSL
specification will clarify this.

d623eeb37a glsl: Fix condition to generate shader link error
GL_ARB_ES2_compatibility doesn't say anything about shader linking
when one of the shaders (vertex or fragment shader) is absent. So,
the extension shouldn't change the behavior specified in GLSL

Tested the behavior on proprietary linux drivers of NVIDIA and AMD.
Both of them allow linking a version 100 shader program in OpenGL
context, when one of the shaders is absent.

20eb466999 r600g,radeonsi: Consolidate logic for short-circuiting flushes
Fixes radeonsi emitting command streams to the kernel even when there
have been no draw calls before a flush, potentially powering up the GPU
needlessly.

Incidentally, this also cuts the runtime of piglit gpu.py in about half
on my Kaveri system, probably because an X11 client going away no longer
always results in a command stream being submitted to the kernel via
glamor.

a889b8e9aa main: Avoid double-free of shader Label
As documented, the _mesa_free_shader_program_data function:

	"Frees all the data that hangs off a shader program object, but not
	the object itself."

This means that this function may be called multiple times on the same object,
(and has been observed to). Meanwhile, the shProg->Label field was not being
set to NULL after its free(). This led to a second call to free() of the same
address on the second call to this function.

Fix this by setting this field to NULL after free(), (just as with all other
calls to free() in this function).

69bd4ed017 glsl: Add locking to builtin_builder singleton
Consider a multithreaded program with two contexts A and B, and the
following scenario:

1. Context A calls initialize(), which allocates mem_ctx and starts
   building built-ins.
2. Context B calls initialize(), which sees mem_ctx != NULL and assumes
   everything is already set up.  It returns.
3. Context B calls find(), which fails to find the built-in since it
   hasn't been created yet.
4. Context A finally finishes initializing the built-ins.

This will break at step 3.  Adding a lock ensures that subsequent
callers of initialize() will wait until initialization is actually
complete.

Similarly, if any thread calls release while another thread is still
initializing, or calling find(), the mem_ctx/shader would get free'd while
from under it, leading to corruption or use-after-free crashes.

Fixes sporadic failures in Piglit's glx-multithread-shader-compile.

This patch swaps the two enum names, reversing them.  This should undo

70e8ec38b5 glx: Pass NULL DRI drawables into the DRI driver for None GLX drawables
GLX_ARB_create_context allows making a GLX context current with None
drawable and readables, but this was never implemented correctly in GLX.
We would create a __DRIdrawable for the None GLX drawable and pass that
to the DRI driver and that would somehow work.  Now it's somehow broken.

The way this should have worked is that we pass a NULL DRI drawable
to the DRI driver when the GLX user calls glXMakeContextCurrent()
with None for drawable and readables.

ecaf9259e9 glsl: Don't lose precision qualifiers when encountering "centroid".
Mesa fails to retain the precision qualifier when parsing:

   #version 300 es
   centroid in mediump vec2 v;

Consider how the parser's type_qualifier production is applied.
First, the precision_qualifier rule creates a new ast_type_qualifier:

    <precision: mediump>

Then the storage_qualifier rule creates a second one:

    <flags: in>

and calls merge_qualifier() to fold in any previous qualifications,
returning:

    <flags: in, precision: mediump>

Finally, the auxiliary_storage_qualifier creates one for "centroid":

    <flags: centroid>

it then does $$ = $1 and $$.flags |= $2.flags, resulting in:

    <flags: centroid, in>

Since precision isn't stored in the flags bitfield, it is lost.  We need
to instead call merge_qualifier to combine all the fields.

0fb761b404 st/mesa: avoid sw fallback for getting/decompressing textures
If st_GetTexImage() is to decompress the texture, avoid the fallback
path even if prefer_blit_based_texture_transfer = false.  For drivers
that returned PIPE_CAP_PREFER_BLIT_BASED_TEXTURE_TRANSFER = 0, we
were always taking the fallback path for texture decompression rather
than rendering a quad.  The later is a lot faster.

ee632e68bd glsl: Fix continue statements in do-while loops.
From the GLSL 4.40 spec, section 6.4 (Jumps):

    The continue jump is used only in loops. It skips the remainder of
    the body of the inner most loop of which it is inside. For while
    and do-while loops, this jump is to the next evaluation of the
    loop condition-expression from which the loop continues as
    previously defined.

Previously, we incorrectly treated a "continue" statement as jumping
to the top of a do-while loop.

This patch fixes the problem by replicating the loop condition when
converting the "continue" statement to IR.  (We already do a similar
thing in "for" loops, to ensure that "continue" causes the loop
expression to be executed).

Fixes piglit tests:
- glsl-fs-continue-inside-do-while.shader_test
- glsl-vs-continue-inside-do-while.shader_test
- glsl-fs-continue-in-switch-in-do-while.shader_test
- glsl-vs-continue-in-switch-in-do-while.shader_test

b5c99be4af glsl: Make condition_to_hir() callable from outside ast_iteration_statement.
In addition to making it public, we also need to change its first
argument from an ir_loop * to an exec_list *, so that it can be used
to insert the condition anywhere in the IR (rather than just in the
body of the loop).

This will be necessary in order to make continue statements work
properly in do-while loops.

165868d45e i965/blorp: do not use unnecessary hw-blending support
This is really not needed as blorp blit programs already sample
XRGB normally and get alpha channel set to 1.0 automatically by
the sampler engine. This is simply copied directly to the payload
of the render target write message and hence there is no need for
any additional blending support from the pixel processing pipeline.

The blending formula is anyway broken for color components, it
multiplies the color component with itself (blend factor is the
component itself).
Alpha blending in turn would not fix the alpha to one independent
of the source but simply used the source alpha as is instead
(1.0 * src_alpha + 0.0 * dst_alpha).

Quoting Eric:

 "If we want to actually make the no-alpha-bits-present thing work,
  we need to override the bits in the surface state or in the
  generated code.  In the normal draw path, it's done for sampling
  by the swizzling code in brw_wm_surface_state.c, and the blending
  overrides is just to fix up the alpha blending stage which
  doesn't pay attention to that for the destination surface."

If one modifies piglit test gl-3.2-layered-rendering-blit to use
color component values other than zero or one, this change will
kick in on IVB. No regressions on IVB.

This is effectively revert of c0554141a9:

    i965/blorp: Support overriding destination alpha to 1.0.

    Currently, Blorp requires the source and destination formats to be
    equal.  However, we'd really like to be able to blit between XRGB and
    ARGB formats; our BLT engine paths have supported this for a long time.

    For ARGB -> XRGB, nothing needs to occur: the missing alpha is already
    interpreted as 1.0.  For XRGB -> ARGB, we need to smash the alpha
    channel to 1.0 when writing the destination colors.  This is fairly
    straightforward with blending.

    For now, this code is never used, as the source and destination formats
    still must be equal.  The next patch will relax that restriction.

    NOTE: This is a candidate for the 9.1 branch.
