In the GLSL 1.30 spec, section 4.3.6 ("Outputs") says:
"If a vertex output is a signed or unsigned integer or integer
vector, then it must be qualified with the interpolation qualifier
flat."
The GLSL ES 3.00 spec further clarifies, in section 4.3.6 ("Output
Variables"):
"Vertex shader outputs that are, *or contain*, signed or unsigned
integers or integer vectors must be qualified with the
interpolation qualifier flat."
(Emphasis mine.)
The language in the GLSL ES 3.00 spec is clearly correct and should be
applied to all shading language versions, since varyings that contain
ints can't be interpolated, regardless of which shading language
version is in use.
(Note that in GLSL 1.50 the restriction is changed to apply to
fragment shader inputs rather than vertex shader outputs, to
accommodate the fact that in the presence of geometry shaders, vertex
shader outputs are not necessarily interpolated. That will be
addressed by a future patch).

GLSL ES 1.00 has similar language. GLSL 1.30 doesn't allow precision

the intention of including these in GLSL 1.30 is to allow

Since transform feedback needs to be able to access individual fields

Instead, we build up a hashtable which records information about each

match up the arguments to glTransformFeedbackVaryings() with the

Populating the hashtable uses the program_resource_visitor

Currently, Blorp requires the source and destination formats to be

For ARGB -> XRGB, nothing needs to occur: the missing alpha is already

channel to 1.0 when writing the destination colors. This is fairly
straightforward with blending.

The BLT engine has many limitations. Currently, it can only blit
X-tiled buffers (since we don't have a kernel API to whack the BLT
tiling mode register), which means all depth/stencil operations get
punted to meta code, which can be very CPU-intensive.
Even if we used the BLT engine, it can't blit between buffers with
different tiling modes, such as an X-tiled non-MSAA ARGB8888 texture
and a Y-tiled CMS ARGB8888 renderbuffer. This is a fundamental
limitation, and the only way around that is to use BLORP.
Previously, BLORP only handled BlitFramebuffer. This patch adds an
additional frontend for doing CopyTexSubImage. It also makes it the
default. This is partly to increase testing and avoid hiding bugs,
and partly because the BLORP path can already handle more cases. With
trivial extensions, it should be able to handle everything the BLT can.
This helps PlaneShift massively, which tries to CopyTexSubImage2D
between depth buffers whenever a player casts a spell. Since these
are Y-tiled, we hit meta and software ReadPixels paths, eating 99% CPU
while delivering ~1 FPS. This is particularly bad in an MMO setting
because people cast spells all the time.
It also helps Xonotic in 4X MSAA mode. At default power management
settings, I measured a 6.35138% +/- 0.672548% performance boost (n=5).

already tells us how much VUE data exists, we didn't bother worrying
about restriction (a); we just did the easy thing and programmed the
read length to satisfy restriction (b).
However, we didn't notice this erratum in the hardware docs: "[errata]
Corruption/Hang possible if length programmed larger than recommended".
Judging by the context surrounding this erratum, it's pretty clear that
it means "URB read length must be exactly the size necessary to read all
the VUE data that the SF needs, and no larger". Which means that we
can't program the read length based on restriction (b)--we have to
program it based on restriction (a).
The URB read size needs to precisely match the amount of data that the
SF consumes; it doesn't work to simply base it on the size of the VUE.
Thankfully, the PRM contains the precise formula the hardware expects.
Fixes random UI corruption in Steam's "Big Picture Mode", random terrain
corruption in PlaneShift, and Piglit's fbo-5-varyings test.
NOTE: This is a candidate for all stable branches.

(cherry picked from commit 9add4e8038)
In the documentation for BindBufferRange, OpenGL specs from 3.0
through 4.1 contain this language:
"The error INVALID_VALUE is generated if size is less than or
equal to zero or if offset + size is greater than the value of
BUFFER_SIZE."
This text was dropped from OpenGL 4.2, and it does not appear in the
GLES 3.0 spec.
Presumably the reason for the change is because come clients change
the size of the buffer after calling BindBufferRange. We don't want
to generate an error at the time of the BindBufferRange call just
because the old size of the buffer was too small, when the buffer is
about to be resized.
Since this is a deliberate relaxation of error conditions in order to
allow clients to work, it seems sensible to apply it to all versions
of GL, not just GL 4.2 and above.
(Note that there is no danger of this change allowing a client to
access data beyond the end of a buffer. We already have code to
ensure that that doesn't happen in the case where the client shrinks
the buffer after calling BindBufferRange).
Eliminates a spurious error message in the gles3 conformance test
"transform_feedback_offset_size".

We are now seing cs that can go over the vram+gtt size to avoid
failing flush early cs that goes over 70% (gtt+vram) usage. 70%
is use to allow some fragmentation.
The idea is to compute a gross estimate of memory requirement of
each draw call. After each draw call, memory will be precisely
accounted. So the uncertainty is only on the current draw call.
In practice this gave very good estimate (+/- 10% of the target
memory limit).
v2: Remove left over from testing version, remove useless NULL
checking. Improve commit message.
v3: Add comment to code on memory accounting precision
