And use this (and the code for r11g11b10 packed float to float conversion)
in the soa texturing code (the generated code looks quite good).
Should be an order of magnitude faster probably than using the fallback
(not measured).
Tested with piglit texwrap GL_EXT_packed_float and
GL_EXT_texture_shared_exponent respectively (didn't find much else using
it).

Initial version contributed by: Martin Andersson <[email protected]>
This is only used if the memcpy path cannot be used and if no transfer ops
are needed. It's pretty similar to our TexImage and GetTexImage
implementations.
The motivation behind this is to be able to use ReadPixels every frame and
still have at least 20 fps (or 60 fps with a powerful GPU and CPU)
instead of 0.5 fps.

I'll need the _mesa_readpixels_needs_slow_path function for the blit-based
version, but it's also useful to have this memcpy-based path in one place
and not scattered across several functions.

I'll need both new functions for later. For now, it consolidates the code
for determining what the transfer ops should be and makes it a little bit

New conversion code to handle conversion from/to r11g11b10 AoS to/from
SoA floats, and also add code for conversion from rgb9e5 AoS to float SoA
(which works pretty much the same as r11g11b10 except for the packing).
(This code should also be used for texture sampling instead of
relying on u_format conversion but it's not yet, so rgb9e5 is unused.)
Unfortunately a crazy amount of hacks is necessary to get the conversion
code running in llvmpipe's generate_unswizzled_blend, which isn't well
suited for formats where the storage representation has nothing to do
with what's needed for blending (moreover, the conversion will convert
from packed AoS values, which is the storage format, to float SoA values,
because this is much more natural for the conversion, and likewise from
SoA values to packed AoS values - but the "blend" (which includes
trivial things like partial mask) works on AoS values, so incoming fs
values will go SoA->AoS, values from destination will go packed
AoS->SoA->AoS, then do blend, then AoS->SoA->packed AoS which probably
isn't the most efficient way though the shuffles are probably bearable).
Passes piglit fbo-blending-formats (with GL_EXT_packed_float parameter),
still need to verify Inf/NaNs (where most of the complexity in the
conversion comes from actually).
v2: drop the (very bogus) rgb9e5 part, and do component extraction
in the helper code for r11g11b10 to float conversion, making the code
slightly more compact (suggested by Jose), now that there are no other
callers left this works quite well. (Could do the same for the
opposite way but it's less than ideal there, final part of packing
needs to be done in caller anyway and there'd be another conditional.)
v3: minor style and comment fixes. Also fix a potential issue with
negative zero being potentially returned by max(src, zero) as we
don't have well-defined min/max behavior (fortunately no additonal cost).

Normally when submitting the first batch buffer after a flush, we
check whether the GPU has completed processing of the first batch
buffer of the previous frame. If it hasn't, we wait for it to finish
before submitting any more batches. This prevents GPU-heavy and
CPU-light applications from racing too far ahead of the current frame,
but at the expense of possibly lower frame rates. Sometimes when
benchmarking we want to disable this mechanism.
This patch adds the driconf option "disable_throttling" to disable the
throttling mechanism.

Commit 33599433c7 began setting the texture swizzle mode to XYZ1 for
RED, RG, and RGB textures in order to force alpha to 1.0 in case we
actually stored the texture as RGBA.
This had a unforseen performance implication: the shader precompile
assumes that the texture swizzle mode will be XYZW for non-shadow
sampler types. By setting it to XYZ1, this means every shader used with
a RED, RG, or RGB texture has to be recompiled. This is a very common
case.
Unfortunately, there's no way to improve the precompile, since RGBA
textures still need XYZW, and there's no way to know by looking at
the shader source what texture formats might be used.
However, we only need to smash alpha to 1.0 if the texture's memory
format actually has alpha bits. If not, the sampler already returns 1.0
for us without any special swizzling. XRGB8888, for example, is a very
common case where this occurs.
This partially fixes a performance regression since commit 33599433c7.
More work is required to fully fix it in all cases. This at least helps
Warsow.

With the old context creation mechanism, an application asked the GL to
give it a context. Failing to produce a context was a fatal error.
Now, with GLX_ARB_create_context, the application can request a specific
version. If it's higher than the maximum version we support, context
creation will fail. But this is a normal error that applications
recover from.
In particular, the new glxinfo tries to create OpenGL 4.3, 4.2, 4.1,
4.0, 3.3, and 3.2 contexts before finally succeeding at creating a 3.1
context. This led to it printing the following message 6 times:
"brwCreateContext: failed to init intel context"
There's no need to alarm users (and developers) with such a message.

On an INTEL_DEBUG=perf piglit run on IVB, reduces the instances of "HW
workaround: blit" (the printouts from the misaligned-depth workaround
blits) from 725 to 675.
It doesn't totally eliminate the workaround blit, because we still have
problems with Y offsets that we can't fix (since texturing can only align
miplevels up to 2 or 4, not 8).
No regressions on piglit/es3conform on IVB.

Previous to this patch, when using fixed function fragment shading,
bit VARYING_BIT_POS of brw_wm_prog_key::proj_attrib_mask was being set
differently during precompiles and normal usage. During precompiles
it was being set only if the fragment shader reads from window
position (which it never does), so it was always being set to 0.
During normal usage it was being set if the vertex shader writes to
all 4 components of gl_Position (which it usually does), so it was
usually being set to 1. As a result, we were almost always doing an
extra recompile for the fixed function fragment shader.
The recompile was totally unnecessary, though, because
brw_wm_prog_key::proj_attrib_mask is only consulted for
fs_visitor::emit_general_interpolation(), which isn't used for
VARYING_SLOT_POS.
This patch avoids the unnecessary recompile by always setting bit
VARYING_BIT_POS of brw_wm_prog_key::proj_attrib_mask to 1.

Previously, right after calling _mesa_glsl_link_shader(), the fixed
function fragment shader code made several calls with the ostensible
purpose of setting up uniforms for the fragment shader it just
created.
These calls are unnecessary, since _mesa_glsl_link_shader() calls
driver->LinkShader(), which takes care of calling these functions (or
their equivalent). Also, they are dangerous to call after
_mesa_glsl_link_shader() has returned, because on back-ends such as
i965 which do precompilation, _mesa_glsl_link_shader() may have
already cached pointers to the existing uniform structures; attempting
to set up the uniforms again invalidates those cached pointers.
It was only by sheer coincidence that this wasn't manifesting itself
as a bug. It turns out that i965's precompile mechanism was always
setting bit 0 of brw_wm_prog_key::proj_attrib_mask to 0 for fixed
function fragment shaders, but during normal usage this bit usually
gets set to 1. As a result, the precompiled shader (with its invalid
uniform pointers) was not being used.
I'm about to introduce some changes that cause bit 0 of
proj_attrib_mask to be set consistently between precompilation and
normal usage, so to avoid regressions I need to get rid of the
dangerous duplicate uniform setup code first.

Since apps typically begin rendering with a call to glClear(), it is
likely that when brw_workaround_depthstencil_alignment() moves a
miplevel to a temporary buffer, it can avoid doing a blit, since the
contents of the miplevel are about to be erased.
This patch adds the necessary plumbing to determine when
brw_workaround_depthstencil_alignment() is being called as a
consequence of glClear(), and avoids the unnecessary blit when it is
safe to do so.

If we're in some conditional or loop we must not return, or the code
after the condition is never executed.
(v2): And, we also can't just continue as nothing happened, since the
mask update code would later check if we actually have a mask, so we
need to remember that there was a return in main where we didn't exit
(to illustrate this, a ret in a if clause would cause a mask update
which is still ok as we're in a conditional, but after the endif the
mask update code would drop the mask hence bringing execution back to
pixels which should have their execution mask set to zero by the ret).
Thanks to Christoph Bumiller for figuring this out.
