This was ridiculous. We were ignoring the inst->header.saturate flag in the
case of math and only math. On gen4, we would leave inst->header.saturate in
place if it happened to be set, which would end up being applied to the
implicit mov and thus trash the first argument. On gen6, we would overwrite
inst->header.saturate with the saturate flag from the argument, which was not
set appropriately in brw_vec4_emit.cpp, and was only not a bug due to our
incompetence at coalescing saturate moves.
By ripping the argument out and making saturate work just like all the other
brw_eu_emit.c code generation, we can avoid both these classes of bugs.

On Gen4+, brw_finish_batch() calls brw_emit_query_end(), which emits
some extra PIPE_CONTROLs to capture the current occlusion query data.
Unfortunately, it was being called *after* _intel_batchbuffer_flush
added the MI_BATCH_BUFFER_END, meaning those PIPE_CONTROLs didn't get
inside the batch.
Not only does this likely cause bogus occlusion query values, it can
also cause crashes: with the recent change to use 64-bit depth count
writes on Gen6+, we started emitting an odd-length PIPE_CONTROL, which
happened after the MI_NOOP padding. This resulted in an odd-length
batch buffer, which resulted in execbuf2 returning -EINVAL and the
application dying with an intel_do_flush_locked failure.
On older generations, finish_batch() doesn't emit any state, so this
change shouldn't have any effect.

This patch depends on some other patches that were not picked over. As
a result, this patch causes a bunch of piglit regressions on SNB.
This reverts commit 55d23cfc56.
Prior to commit afaf5b59e, emit_fb_writes() looped from 0 to 3, writing
all four components of a vec4 color output. However, that broke for
smaller output types (float, vec2, or vec3). To fix that, I introduced
a new variable (output_components[]) containing the size of the output
type for each render target.
Unfortunately, I forgot to actually initialize it in the constructor,
which meant that unless a shader wrote to gl_FragColor, or the specific
output for each render target, output_components would contain a garbage
value, and we'd loop for a completely non-deterministic amount of time.
Not actually emitting any color writes seems like the right approach.
We may still need to emit a render target write (to terminate the
thread), but don't have to put in any sensible values (the shader didn't
write anything, after all).
Fixes a regression since afaf5b59e4.

(cherry picked from commit 5e310e9f83)
On i965, dFdx() and dFdy() are computed by taking advantage of the
fact that each consecutive set of 4 pixels dispatched to the fragment
shader always constitutes a contiguous 2x2 block of pixels in a fixed
arrangement known as a "sub-span". So we calculate dFdx() by taking
the difference between the values computed for the left and right
halves of the sub-span, and we calculate dFdy() by taking the
difference between the values computed for the top and bottom halves
of the sub-span.
However, there's a subtlety when FBOs are in use: since FBOs use a
coordinate system where the origin is at the upper left, and window
system framebuffers use a coordinate system where the origin is at the
lower left, the computation of dFdy() needs to be negated for FBOs.
This patch modifies the fragment shader back-ends to negate the value
of dFdy() when an FBO is in use. It also modifies the code that
populates the program key (brw_wm_populate_key() and
brw_fs_precompile()) so that they always record in the program key
whether we are rendering to an FBO or to a window system framebuffer;
this ensures that the fragment shader will get recompiled when

This will result in unnecessary recompiles of fragment shaders that

Function calls may have side effects that alter variables used inside
the loop. In the fragment shader, they may even terminate the shader.
This means our analysis about loop-constant or induction variables may
be completely wrong.
In general it's impossible to determine whether they actually do or not
(due to the halting problem), so we'd need to perform conservative
static analysis. For now, it's not worth the complexity: most functions
will be inlined, at which point we can unroll them successfully.

(cherry picked from commit 3603fdcebf)
OpenGL allows you to declare user-defined fragment shader outputs with
less than four components:
out ivec2 color;
This makes sense if you're rendering to an RG format render target.
Previously, we assumed that all color outputs had four components (like
the built-in gl_FragColor/gl_FragData variables). This caused us to
call emit_color_write for invalid indices, incrementing the output
virtual GRF's reg_offset beyond the size of the register.
This caused cascading failures: split_virtual_grfs would allocate new
size-1 registers based on the virtual GRF size, but then proceed to
rewrite the out-of-bounds accesses assuming that it had allocated enough
new (contiguously numbered) registers. This resulted in instructions
that accessed size-1 GRFs which register numbers beyond
virtual_grf_next (i.e. registers that were never allocated).
Finally, this manifested as live variable analysis and instruction
scheduling accessing their temporary array with an out of bounds index
(as they're all sized based on virtual_grf_next), and the program would
segfault.
It looks like the hardware's Render Target Write message requires you to
send four components, even for RT formats such as RG or RGB. This patch
continues to use all four MRFs, but doesn't bother to fill any data for
the last few, which should be unused.

A lot of code, such as lower_jumps, allocates new loop jumps without

This patch removes ARB_framebuffer_object from the GLES1 and GLES2
extension lists in intel_extensions_es.c.
Fixes a crash in the Android browser on Ice Cream Sandwich.
The Android browser crashed because it did the following, which is legal
in GLES2 but not in ARB_framebuffer_object.
glGenFramebuffers(1, &fb);
glBindFramebuffer(GL_FRAMEBUFFER, fb);
// render render render...
glDeleteFramebuffers(1, &fb);
// go do other stuff...
glBindFramebuffer(GL_FRAMEBUFFER, fb);
// This bind unexpectedly failed, and the app panics.
The semantics of glBindFramebuffer specified by ARB_framebuffer_object (a
desktop GL extension) and GLES2 specs are incompatible. The ideal solution
to fix this is to create separate API entry points for glBindFramebuffer,
one for GL and the other for GLES2. But, until that work is complete,
disabling ARB_framebuffer_object in GLES2 contexts safely fixes the problem.
Likewise, the semantics of glBindFramebuffer in ARB_framebuffer_object and
of glBindFramebufferOES in OES_framebuffer_object (a GLES1 extension) are
incompatible. Even though the functions have different names, the semantic
difference still results in a bug because both API calls are implemented
by a single function, _mesa_BindFramebufferEXT, which handles the semantic
difference incorrectly. Again, disabling ARB_framebuffer_object in GLES1
contexts safely fixes this problem.
According to the ARB_framebuffer_object spec, the extension is an
amalgamation of
EXT_framebuffer_object
EXT_framebuffer_blit
EXT_packed_depth_stencil
EXT_framebuffer_multisample
By disabling this extension, however, no functionality is removed from
GLES1 and GLES2 contexts because 1) the first three extensions are
explicitly enabled in Intel's ES extension lists and 2) no functionality
of the last extension is exposed in an ES context.

The application supplied [start, end] range is merely a conservative
hint of the ranges of index values inside the index buffer. There is no
requirement that all vertices in the range [start, end] be referenced.
Passing an 'end' value larger than the maximum legal index is perfectly
acceptible; applications can legally pass 0xffffffff when they don't
have a tighter bound readily available.
Thus, the warning doesn't indicate a correctness issue; it could only
indicate a performance issue. However, it does not even do that.
glDrawRangeElements is designed to optimize non-VBO vertex data uploads
by providing an upper bound on the size of buffers a driver would need
to allocate. With VBOs, the data is already in an uploaded buffer, so
the range doesn't help.
The clincher is: we only know _MaxElement for VBOs. For user-space
arrays, we just set it to 2,000,000,000 (see mesa/main/varray.h:63.)
So we can only check this in the case where it is not useful.
Many applications, including the Unigine demos, currently trigger this
warning, which suggests the applications are buggy when they're actually
fine. Eliminating the warning should confuse users less while not
actually losing any benefit to application developers.

There's a serious trap for drivers: RenderTexture() does not indicate
that the texture is currently bound to the draw buffer, despite
FinishRenderTexture() signaling that the texture is just now being
unbound from the draw buffer.
We were acting as if RenderTexture() *was* the start of rendering and
that we could make texturing incoherent with the current contents of
the renderbuffer. This caused intel oglconform sRGB
Mipmap.1D_textures to fail, because we got a call to TexImage() and
thus RenderTexture() on a texture bound to a framebuffer that wasn't
the draw buffer, so we skipped validating the new image into the
texture object used for rendering.
We can't (easily) make RenderTexture() indicate the start of drawing,
because both our driver and gallium are using it as the moment to set
up the renderbuffer wrapper used for things like MapRenderbuffer().
Instead, postpone the setup of the workaround render target miptree
until update_renderbuffer time, so that we no longer need to skip
validation of miptrees used as render targets. As a bonus, this
should make GL_NV_texture_barrier possible.
(This also fixes a regression in the gen4 small-mipmap rendering since
3b38b33c16, which switched
set_draw_offset from image->mt to irb->mt but didn't move the irb->mt
replacement up before set_draw_offset).

exits the shader, and subsequent implicit or explicit derivatives
are undefined when this control flow is non-uniform (meaning
different fragments within the primitive take different control
paths).

A little analysis shows that the worst-case value for "nr" is 17:
- base_mrf = 2 ... 2
- header present (say gen == 5) ... 4
- aa_dest_stencil_reg (stencil test) ... 5
- SIMD16 mode: += 4 * reg_width ... 13
- source_depth_to_render_target ... 15
- dest_depth_reg ... 17
This resulted in us setting base_mrf to 2 and mlen to 15. In other
words, we'd try to use m2..m16. But m16 doesn't exist pre-Gen6. Also,
the instruction scheduler data structures use arrays of size 16, so this
would cause us to access them out of bounds.
While the debugger system routine may need m0 and m1, we don't use it
today, so the simplest solution is just to move base_mrf back to 1.
That way, our worst case message fits in m1..m15, which is legal.
An alternative would be to fail on SIMD16 in this case, but that seems
a bit unfortunate if there's no real need to reserve m0 and m1.

This patch add the support of gl_PointCoord gl builtin variable for
platform gen4 and gen5(ILK).
Unlike gen6+, we don't have a hardware support of gl_PointCoord, means
hardware will not calculate the interpolation coefficient for you.
Instead, you should handle it yourself in sf shader stage.
But badly, gl_PointCoord is a FS instead of VS builtin variable, thus
it's not included in c.vue_map generated in VS stage. Thus the current
code doesn't aware of this attribute. And to handle it correctly, we
need add it to c.vue_map manually to let SF shader generate the needed
interpolation coefficient for FS shader. SF stage has it's own copy of
vue_map, thus I think it's safe to do it manually.
Since handling gl_PointCoord for gen4 and gen5 platforms is somehow a
little special, I added a lot of comments and hope I didn't overdo it ;)

Mesa has a fast path for the generic fallback when using glReadPixels

hit this case because it would not be used if any transferOps are

types (so any of the common types) would force enabling clamping so
the fast path could not be used. This patch makes it ignore clamping
when determining whether to use the fast path if the data type of the
buffer is an unsigned normalized type because in that case clamping
will not have any effect anyway.

Commit dc7f449d1a introduced a new method
for avoiding MOVs: try to rewrite the destination of the instruction
that produced the RHS so it writes into the LHS.
Unfortunately, this is not safe for swizzled texturing operations, as
they return a set of four contiguous registers. Consider the following:
(assign (x)
(var_ref vec_ctor_x)
(swiz x (tex vec4 (var_ref m_sampY) (var_ref m_cordY) 0 1 ())))
In this case, the source and destination registers are equal, since
reg_offset is 0 for both. Yet, this is only a partial move: the texture
operation generates four registers, and the LHS only covers one.

This is a combination of 4 commits. The first commit rewrites the HiZ op,
and remaining three fix bugs introduced by the rewrite.
======== commit 1 ========
i965: Rewrite the HiZ op
The HiZ op was implemented as a meta-op. This patch reimplements it by
emitting a special HiZ batch. This fixes several known bugs, and likely
a lot of undiscovered ones too.
==== Why the HiZ meta-op needed to die ====
The HiZ op was implemented as a meta-op, which caused lots of trouble. All
other meta-ops occur as a result of some GL call (for example, glClear and
glGenerateMipmap), but the HiZ meta-op was special. It was called in
places that Mesa (in particular, the vbo and swrast modules) did not
expect---and were not prepared for---state changes to occur (for example:
glDraw; glCallList; within glBegin/End blocks; and within
swrast_prepare_render as a result of intel_miptree_map).
In an attempt to work around these unexpected state changes, I added two
hooks in i965:
- A hook for glDraw, located in brw_predraw_resolve_buffers (which is
called in the glDraw path). This hook detected if a predraw resolve
meta-op had occurred, and would hackishly repropagate some GL state
if necessary. This ensured that the meta-op state changes would not
intefere with the vbo module's subsequent execution of glDraw.
- A hook for glBegin, implemented by brwPrepareExecBegin. This hook
resolved all buffers before entering
a glBegin/End block, thus preventing an infinitely recurring call to
vbo_exec_FlushVertices. The vbo module calls vbo_exec_FlushVertices to
flush its vertex queue in response to GL state changes.
Unfortunately, these hooks were not sufficient. The meta-op state changes
still interacted badly with glPopAttrib (as discovered in bug 44927) and
with swrast rendering (as discovered by debugging gen6's swrast fallback
for glBitmap). I expect there are more undiscovered bugs. Rather than play
whack-a-mole in a minefield, the sane approach is to replace the HiZ
meta-op with something safer.
==== How it was killed ====
This patch consists of several logical components:
1. Rewrite the HiZ op by replacing function gen6_resolve_slice with
gen6_hiz_exec and gen7_hiz_exec. The new functions do not call
a meta-op, but instead manually construct and emit a batch to "draw"
the HiZ op's rectangle primitive. The new functions alter no GL
state.
2. Add fields to brw_context::hiz for the new HiZ op.
3. Emit a workaround flush when toggling 3DSTATE_VS.VsFunctionEnable.
4. Kill all dead HiZ code:
- the function gen6_resolve_slice
- the dirty flag BRW_NEW_HIZ
- the dead fields in brw_context::hiz
- the state packet manipulation triggered by the now removed
brw_context::hiz::op
- the meta-op workaround in brw_predraw_resolve_buffers (discussed
above)
- the meta-op workaround brwPrepareExecBegin (discussed above)

In commit 6ecee54a9a a call to
talloc_reference was replaced with a call to talloc_steal. This was in
preparation for moving to ralloc which doesn't support reference
counting.
The justification for talloc_steal within token_list_append in that
commit is that the tokens are being copied already. But the copies are
shallow, so this does not work.
Fortunately, the lifetime of these tokens is easy to understand. A
token list for "replacements" is created and stored in a hash table
when a function-like macro is defined. This list will live until the
macro is #undefed (if ever).
Meanwhile, a shallow copy of the list is created when the macro is
used and the list expanded. This copy is short-lived, so is unsuitable
as a new parent.
So we can just let the original, longer-lived owner continue to own
the underlying objects and things will work.

To avoid using the empty program, this patch 1) defines a new function,
_swrast_use_fragment_program, which checks if the current fragment program
exists and differs from the fixed function fragment program, and, when
appropriate, 2) replaces checks of the form

FBOs differ from textures in a significant way. With textures, we can
strip the border and get correct rendering except when the application

With an FBO, the pixel at (0,0) is in the border. The
ARB_framebuffer_object spec says:
"If the attached image is a texture image, then the window
coordinates (x[w], y[w]) correspond to the texel (i, j, k), from
figure 3.10 as follows:
i = (x[w] - b)
j = (y[w] - b)
k = (layer - b)

Ever since xserver commit 531869448d07e00ae241120b59f3aaaa5709d59c,
the server no longer sends invalidate events to clients, unless they
have performed a GetBuffers request since the drawable was last
invalidated.
If the drawable gets invalidated immediately after the GetBuffers
request was processed by the X server, it's possible that Xlib
will process the invalidate event while waiting for the GetBuffers
reply. So the server, thinking the client knows that the buffers
are invalid, is waiting for another GetBuffers request before
sending any more invalidate events. The client, on the other hand,
believes the buffers to be valid, and thus is expecting to receive
another invalidate event before it has to send another GetBuffers
request. The end result is that the client never again sends
a GetBuffers request.
To avoid this problem, take a snapshot of the lastStamp before
doing GetBuffers, and retry if the snapshot and the current
lastStamp no longer match after the GetBuffers reply has been
processed.

(cherry picked from commit 6bc08ee569)
i965 processes assignments of whole structures using
vec4_visitor::emit_block_move, a recursive function which visits each
element of a structure or array (to arbitrary nesting depth) and
copies it from the source to the destination. Then it increments the
source and destination register numbers so that further recursive
invocations will copy the rest of the structure. In addition, it sets
the swizzle field for the source register to an appropriate value of
swizzle_for_size(...) for the size of each element being copied, so
that later optimization passes won't be fooled into thinking that
unused vector elements are live.
This all works fine. However, emit_block_move also contains an
assertion to verify, before setting the swizzle field for the source
register, that the source register doesn't already contain a
nontrivial swizzle. The intention is to make sure that the caller of
emit_block_move hasn't already done some swizzling of the data before
the call, which emit_block_move would then counteract when it
overwrites the swizzle field. But the assertion is at the lowest
level of nesting of emit_block_move, which means that after the first
element is copied, instead of checking the swizzle field set by the
caller, it checks the swizzle field used when moving the previous
element. That means that if the structure contains elements of
different vector sizes (which therefore require different swizzles),
the assertion will erroneously fire.
This patch moves the assertion from emit_block_move to the calling
function, vec4_visitor::visit(ir_assignment *). Since the caller is
non-recursive, the assertion will only happen once, and won't be
fooled by emit_block_move's modification of the swizzle field.
This patch also reverts commit fe006a7 (i965/vs: Fix swizzle related
assertion), which attempted to fix the bug by making the assertion
more lenient, but only worked properly for structures, arrays, and
matrices in which each constituent vector is the same size.
This fixes the problem described in comment 9 of
https://bugs.freedesktop.org/show_bug.cgi?id=40865. Unfortunately, it
doesn't fix the whole bug, since the test in question is also failing

"the surface pitch is ignored, the surface is treated as a

used to determine the size of the buffer for out-of-bounds
checking if using the surface state model."
Previously we were setting the pitch for pull constant buffers to the

This loosens the format validation in glBlitFramebuffer. When blitting
depth bits, don't require an exact match between the depth formats; only
require that the two formats have the same number of depth bits and the
same depth datatype (float vs uint). Ditto for stencil.
Between S8_Z24 buffers, the EXT_framebuffer_blit spec allows
glBlitFramebuffer to blit the depth and stencil bits separately. So I see
no reason to prevent blitting the depth bits between X8_Z24 and S8_Z24 or
the stencil bits between S8 and S8_Z24. However, we of course don't want
to allow blitting from Z32 to Z32_FLOAT.
Fixes Piglit fbo/fbo-blit-d24s8 on Intel drivers with separate stencil
enabled.
The problem was that, on Intel drivers with separate stencil, the default
framebuffer has separate depth and stencil buffers with formats X8_Z24 and
S8. The test attempts to blit the depth bits from a S8_Z24 buffer into the
default framebuffer.
v2: Check that depth datatypes match.

When I originally implemented the hack to use GRFs 111+ as fake MRFs, I
did so purely to avoid rewriting all the code that dealt with MRFs.
However, it turns out that a similar hack is actually required.
Newly discovered language in the BSpec indicates that SEND instructions
with EOT set "should" use g112-g127 as their source registers. Based on
assertions in the simulator, this is actually a requirement on certain
platforms.
Since we're faking MRFs already, we may as well use the officially
sanctioned range. My guess is that we avoided this issue because we
seldom use m0: URB writes in the new VS backend start at m1, and RT

The reason this wasn't noticed by Piglit tests is that the size of our
constant surfaces is always less than 2^20, therefore the off-by-one
error was causing the "depth" field of the surface to be set to all
1's. The hardware interpreted this as an extremely large surface, so
overflow checking was effectively disabled.

Previously, we were saying that everything from the starting tile to
region width+height was part of the limits of our depthbuffer, even if
the tile was near the bottom of the depthbuffer. This mean that our
range was not clipping to buffer buonds if the start tile was anything
but the start of the buffer.
In bebc91f0f3, this was changed to
saying that we're just rendering to a region of the size of the
renderbuffer. This is great -- we get a range that should actually
match what we want. However, the hardware's range checking occurs
after the X/Y offset addition, so we were clipping out rendering to
small depth mip levels when an X/Y offset was present. Just add
tile_x/y to the width in that case -- the WM won't produce negative
x/y values pre-offset, so we just need to get the left/bottom sides of
the region to cover our buffer.

<li>Mesa/Gallium master branch. This code is used to build libGL, and the direct rendering svga driver for libGL, vmwgfx_dri.so, and the X acceleration library libxatracker.so.x.x.x.
<li>VMware Linux guest kernel module. Note that this repo contains the complete DRM and TTM code. The vmware-specific driver is really only the files prefixed with vmwgfx.
<li>libdrm, A user-space library that interfaces with drm. Most distros ship with this driver. Safest bet is really to replace the system one. Optionally you can point LIBDRM_CFLAGS and LIBDRM_LIBS to the libdrm-2.4.22 package in toolchain. But here, we replace:
Note that you may have to install other packages that Mesa depends upon
if they're not installed in your system. You should be told what's missing.

<li>xf86-video-vmware: Now, once libxatracker is installed, we proceed with building and replacing the current Xorg driver. First check if your system is 32- or 64-bit. If you're building for a 32-bit system, you will not be needing the --libdir=/usr/lib64 option to autogen.
