The blend state is different and the resolve single-sample buffer must have
FMASK and CMASK enabled. I decided to have one CMASK and one FMASK
per context instead of per resource.
There are new FMASK and CMASK allocation helpers and a new buffer_create
helper for that.
The color resolve on r6xx needs PT_RECTLIST. Using conventional primitive
types (triangles and quads) produces an ugly line between two diagonally
opposite corners. I guess a rectangular point sprite would work too.

Prior to commit 2f1869822, 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 2f18698220.

It is possible to force S3TC extensions to be enabled. This is
generally done to support applications that will only supply
pre-compressed textures. This accounts for the vast majority of
applications.
However, there is still the possibility of an application asking for
on-line compression. In that case, generate a warning and substitute a
generic compressed format. The driver will either pick an uncompressed
format or a compressed format that Mesa can handle on-line (e.g., FXT1).
This should only cause problems for applications that request on-line
compression and read the compressed texture back. This is likely an
infinitesimal subset of an already infinitesimal subset.

Precompiling the shader at link time often allows us to avoid compiling
it at the first use. This moves the expensive compilation and
optimization process to game or level load time, rather than at draw
time, where we really can't avoid any cycles and don't want to risk
stalling the GPU.
The downside is that we have to guess the non-orthagonal state the
program will have set when it draws with the shader. Previously, we
guessed wrong for nearly every shader, so it wasn't useful. With the
recent SamplerUnits rework and this series, we've either eliminated
state or made smarter guesses, and usually get it right now.
In the L4D2 time demo, I now have 39 fragment shader recompiles and no

When assigning uniform locations, the linker assigns each sampler
uniform a sequential numerical ID. gl_shader_program::SamplerUnits maps
these sampler variable IDs to the actual texture units they reference
(specified via glUniform1i).
Previously, we encoded this mapping in the SEND instruction encoding:
the "sampler" was the texture unit number, and the binding table index
was SURF_INDEX_TEXTURE(the texture unit number). This unfortunately
meant that whenever the application changed the value of a sampler
uniform, we had to recompile the shader to change the SEND instructions.
This was horrible for the game Cogs, which repeatedly switches between
using texture unit 0 and 1. It also made fragment shader precompiles
useless: we'd do the precompile at glLinkShader() time, before the
application called glUniform1i to set the sampler values. As soon as
it did that, we'd have to recompile, wasting time and space in the
program cache.
This patch encodes the SamplerUnits indirection in the binding table,
sampler state, and sampler default color tables. Instead of baking the
texture unit number into the shader, we bake in the sampler variable ID
assigned by the linker. Since those never change, we don't need to
recompile programs on uniform changes.
This does mean that the tables now depend on the linked shader program
being used for rendering, rather than simply representing all available
texture units. This could cause an increase in state emission.
Another plus is that the sampler state and sampler default color tables
are now compact: we only emit as many entries as there are sampler
uniforms, with no holes in the table since the new sampler IDs are
sequential. Previously we had to emit a full 16 entries every time,
since the tables tracked the state of all active texture units.

There are three possible resolve map states for each (level, layer) of
a depth miptree: "needs HiZ resolve", "needs depth resolve", and
"needs neither". When HiZ was first implemented on i965, any attempt
to directly transition between "needs HiZ resolve" and "needs depth
resolve" without passing through the "needs neither" state would have
been a bug indicating that a necessary resolve hadn't been performed.
Accordingly, intel_resolve_map_set() contained an assertion to verify
that no such direct transition happened.
However, now that we support fast depth clears, there is a valid
transition from the "needs HiZ resolve" to the "needs depth resolve"
state. When doing a fast depth clear, the old state of the buffer is
irrelevant, since we are completely replacing it with the clear value,
so it is not necessary to do any resolves before clearing--we can
transition, if necessary, directly from the "needs HiZ resolve" state
to the "needs depth resolve" state.

For cube maps, _mesa_generate_mipmap() calls this with
GL_TEXTURE_CUBE_MAP (the gl_texture_object's Target) rather than one
of the faces. This caused _mesa_max_texture_levels() to return 0, which
resulted in maxLevels == -1 and the next line's assertion to fail.
This function is called from seven places:
- fbobject.c: framebuffer_texture()
- mipmap.c: _mesa_generate_mipmap()
- texgetimage.c:
- getteximage_error_check()
- getcompressedteximage_error_check()
- texparam.c: _mesa_GetTexLevelParameteriv()
- texstorage.c: tex_storage_error_check()
All of these (or their callers) now explicitly check for invalid targets
already, so this shouldn't cause invalid targets to slip through.
(Technically _mesa_generate_mipmap() doesn't check for invalid targets,
but the API-facing _mesa_GenerateMipmapEXT() function does.)

In various places we're creating arrays such as
sampler_views[PIPE_SHADER_TYPES][PIPE_MAX_SAMPLERS] so we were assuming
the same number of max samplers for all shader stages anyway.
Of course, drivers are still free to advertise different numbers of max
samplers for different shaders.

the pointer earlier in the code. Now, check for result != NULL first, then

The only allowed instructions are TXQ_LZ and TXF.
TXQ_LZ is like TXQ, but without the LOD parameter (which is always zero
with MSAA textures)
The 3rd or the 4th texcoord component in TXF should contain the sample index
for a 2D_MSAA or 2D_ARRAY_MSAA texture, respectively.
The problem was that the string matching succeeded e.g. for "2D" when there
was actually "2D_MSAA" and then failed parsing "_MSAA".

Reserving a full 60 bytes seems a bit harsh, since we only need that
much if occlusion queries are actually active. Plus, 28 bytes would be
sufficient for Gen7, and 24 for Gen4-5.
We could optimize this in the future, but it doesn't seem too critical.

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.
Huge thanks to Chris Wilson for helping me figure this out.

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.

In between glGenBuffers() and glBindBuffer(), the buffer object points to this

It seems pretty clear, given that glBindBufferBase() only cares about the
current size of the buffer at render time, that it should bind up the buffer
that you passed in instead of pointing it at this useless dummy buffer.
However, what should glBindBufferRange() do? As of this patch, it will
promote the genned buffer to a proper buffer like it had been
glBindBuffer()ed, and then detect that the size is greater than the buffer's
current size of 0 and throw INVALID_VALUE. It seems like the most reasonable
answer here.
Note that this also changes the behavior of these two on non-glGenBuffers() bo
names. We haven't yet set up the error throwing for glBindBuffers() on gl

Consider a texture call such as:
textureLod(s, coordinate, log2(...))
First, we begin setting up the sampler message by loading the texture
coordinates into MRFs, starting with m2. Then, we realize we need the
LOD, and go to compute it with:
ir->lod_info.lod->accept(this);
On Gen4-5, this will generate a SEND instruction to compute log2(),
loading the operand into m2, and clobbering our texcoord.
Similar issues exist on Gen6+. For example, nested texture calls:
textureLod(s1, c1, texture(s2, c2).x)
Any texturing call where evaluating the subexpression trees for LOD or
shadow comparitor would generate SEND instructions could potentially
break. In some cases (like register spilling), we get lucky and avoid
the issue by using non-overlapping MRF regions. But we shouldn't count
on that.

EXT_framebuffer_multisample is a required subpart of
ARB_framebuffer_object, which means that we must support it even on
platforms that don't support MSAA. Fortunately
EXT_framebuffer_multisample allows for this by allowing GL_MAX_SAMPLES
to be set to 1.
This leads to a tricky quirk in the GL spec: since
GlRenderbufferStorageMultisamples() accepts any value for its
"samples" parameter up to and including GL_MAX_SAMPLES, that means
that on platforms that don't support MSAA, GL_SAMPLES is allowed to be
set to either 0 or 1. On platforms that do support MSAA, GL_SAMPLES=1
is not used; 0 means no MSAA, and 2 or higher means MSAA.
In other words, GL_SAMPLES needs to be interpreted as follows:
=0 no MSAA (possible on all platforms)
=1 no MSAA (only possible on platforms where MSAA unsupported)
>1 MSAA (only possible on platforms where MSAA supported)
This patch modifies all MSAA-related code to choose between
multisampling and single-sampling based on the condition (GL_SAMPLES >
1) instead of (GL_SAMPLES > 0) so that GL_SAMPLES=1 will be treated as
"no MSAA".
Note that since GL_SAMPLES=1 implies GL_SAMPLE_BUFFERS=1, we can no
longer use GL_SAMPLE_BUFFERS to distinguish between MSAA and non-MSAA
rendering.

This reverts commit 5d5af7d359.
It turns out the issue this was supposed to fix merely counter-acted
a bug in the hardware driver that I wasn't aware of.
The resource_resolve is not supposed to do sRGB conversion, period.
(This would violate the requirement that source and destination must
be of the same format).
no point in emitting aux scissor values if we
a) never enable them
b) never set the actual values
plus it is enough to have that aux scissor enable reg (which we never set to
enable) in one place not two.
There were several problems with these functions (which are a remnant
of dri1 hyperz mostly - should bring it back somehow someday).
First, it would always do a swrast clear if the buffer to clear was a fbo.
Second, for buffers we wouldn't handle the clear (I guess aux/accum?) we
would actually still have tried to clear that later even when we already
cleared it with swrast.
This addresses one issue raised in bug #51658 discovered by Eugene St Leger.
The assert is bogus since there's no problem with texture width/height being
2048 (the width/height programmed is width/height minus one).
OTOH though the programmed size for scissor rect should be width/height
minus one too otherwise bad things may happen (as it is inclusive, and there's
not enough bits for more than a value of 2047).
SI does not support 64-bit immediates natively, but llvm will generate
i64 immediates when indexing loads and stores (since SI has 64-bit
pointers). The i64 indices will always be small enough to fit into
32-bits (i.e. the high 32 bits will always be all zeros), so we can
treat these index values as 32-bits.
In tablegen, if two patterns match, the one that comes first in the file
is given preference. We want the SMRD IMM pattern to be given
preference, because it encodes the pointer offset in its immediate
field, which saves us an add instruction.

Recently more files were removed from control to be auto-generated
in the dricore library. Android build was not able to locate the
new files if they were not created beforehand.
LOCAL_SRC_FILES includes some of those files and Android.gen.mk
re-defines this variable by filtering out the auto-generated files.
Unfortunately for this variable it is not the same to have the SRCDIR
variable defined as the current directory.
By re-defining SRCDIR for the autotools build the Android build system
is happy again and the new files were actually removed from the sources
to use the auto generated versions.
Also patch d5c1801a01 was partially reverted as the files
can not be compiled to the LOCAL_PATH, instead they should live on the
intermediates folder so that a clean can wipe them out.

The sendc instruction causes the fragment shader thread to wait for
any dependent threads (i.e. threads rendering to overlapping pixels)
to complete before sending the message. We need to use sendc on the
first render target write in order to guarantee that fragment shader
outputs are written to the render target in the correct order.
Previously, we only used the "sendc" instruction when writing to
binding table index 0. This did the right thing for fragment shaders,
because our fragment shader back-ends always issue their first render
target write to binding table index 0. However, it did the wrong
thing for blorp, which performs its render target writes to binding
table index 1.
A more robust solution is to use sendc for all render target writes.
This should not produce any performance penalty, since after the first
sendc, all of the dependent threads will have completed.
For more information about sendc, see the Ivy Bridge PRM, Vol4 Part3
p218 (sendc - Conditional Send Message), and p54 (TDR Registers).

We already provided these files on 'make install', but only created a

Various applications (like the ES2 conformance suite) seem to link

When operating in persample dispatch mode, the blorp engine would
previously assume that subspan N always represented sample N (this is
correct assuming 4x MSAA and a 16-wide dispatch). In order to support
8x MSAA, we must compute which sample is associated with each subspan,
using the "Starting Sample Pair Index" field in the thread payload.

When rendering to an IMS MSAA surface on Gen7, blorp sets up the
rendering pipeline as though it were rendering to a single-sampled
surface; accordingly it must adjust the size of the primitive it sends
down the pipeline to account for the interleaving of samples in an IMS
surface.
This patch modifies the size adjustment code to properly handle 8x
MSAA, which makes room for the extra samples by using an interleaving
pattern that is twice as wide as 4x MSAA.

The steps are the same, but they are now performed in an order that

DrawBuffers support is added.

Previously, the blorp engine would fall back to swrast if the source
or destination of a blit had no associated miptree. This was
unnecessary, since _mesa_BlitFramebufferEXT() already takes care of
making the blit silently succeed if there are no buffers bound, so the
fallback paths could never actually happen in practice.
Removing these fallback paths will simplify the implementation of
correct DrawBuffers support in blorp.

glDeleteShader() is not safe.
This is particularly bad since glDeleteProgram() frees shaders: if you
first call glDeleteShader() on the shaders attached to the program (thus
decrementing the refcount), then called glDeleteProgram(), it would try
to free them again (decrementing the refcount another time), causing
a refcount > 0 assertion to fail.
