i965: Separate miptree creation from auxiliary buffer setup

Currently the logic allocating and setting up miptrees is closely
combined with decision making when to re-allocate buffers in
X-tiled layout and when to associate colors with auxiliary buffers.

These auxiliary buffers are in turn also represented as miptrees
and are created by the same miptree creation logic calling itself
recursively. This means considering in vain if the auxiliary buffers
should be represented in X-tiled layout or if they should be
associated with auxiliary buffers again.
While this is somewhat unnecessary, this doesn't impose any problems
currently. Miptrees for auxiliary buffers are created as simgle-sampled
fusing the consideration for multi-sampled compression auxiliary
buffers. The format in turn is such that is not applicable for
single-sampled fast clears (that would require accompaning auxiliary
buffer).
But once the driver starts to support lossless compression of color
buffers the auxiliary buffer will have a format that would itself
be applicable for lossless compression. This would be rather
difficult and ugly to detect in the current miptree creation logic,
and therefore this patch seeks to separate the association logic
from the general allocation and setup steps.

v2 (Ben):
   - Do not reconsider for X-tiling in intel_miptree_create()
     as it was just forced to Y-tiling in miptree_create().
   - Do not drop checks for allocation failures.

8 years agoi965: Restore vbo after color resolve during brw_try_draw_prims()
Topi Pohjolainen [Wed, 27 Jan 2016 11:08:03 +0000 (13:08 +0200)]
i965: Restore vbo after color resolve during brw_try_draw_prims()

Part of brw_try_draw_prims() is a check to validate textures
(brw_validate_textures()). In case of textures that currently have
only level zero but are marked for mipmap generation, i965 driver
will decide to replace the underlying buffer with a larger one
capable of holding also the additional levels. This results into
blit from the original buffer to the newly allocated (see
intel_miptree_copy_teximage()). This blit is currently handled with
blitter engine and hence it won't effect the ongoing draw operation.
However, this blit in turn may trigger color resolve on the source
buffer. In principle, this should be possible with fast cleared
buffers but I only started hitting it when I enabled lossless
compression (that reguires similar resolve to fast cleared buffers).

Now, the color resolve is a meta operation and uses the same drawing
path we are already in middle of. After quite a bit of debugging I
realized that the resolve will modify the current vbo setup but it
won't restore it afterwards resulting in the original draw call
using wrong vertex data.
When brw_try_draw_prims() gets called, the vbo logic in the Mesa
core (see vbo_draw_arrays()) has just bound the vbo (see
vbo_bind_arrays() and recalculate_input_bindings()). Color resolve
operation will overwrite the vbo setup by calling vbo_bind_arrays()
against the resolve rectangle (see brw_draw_rectlist()). Once the
color resolve is done the vbo setup is left to the resolve rectangle
state and the original drawing call yields bogus results.

This patch aims to restore the original state after the color
resolve by calling vbo_bind_arrays() yet again after the vertex
array state in the core context have been restored.

Now having said all this, I'd also like to state that I'm quite
uncomfortable with the nested meta operations. Ths original draw
call in this case is in fact a meta operation itself. It is a blit
from level zero to level one when generating the additional mipmap
levels (see _mesa_meta_GenerateMipmap()). Imagine the complexity
if the blit in the middle from buffer to another would go to meta
path also instead of blitter.

I would very tempted to try to move all the resolves to happen
before a meta operation is started.
Additionally I still feel that work I did earlier in the spring/
summer time moving meta operations to use direct state upload
bypassing the core context would make sense.

v2: Force input recalculation by setting the flag explicitly

v3: Do not attempt to restore vbo for opengles1 which doesn't
    support vertex buffer objects.

nir: Remove the const_offset from nir_tex_instr

When NIR was originally drafted, there was no easy way to determine if
something was constant or not.  The result was that we had lots of
special-casing for constant values such as this.  Now that load_const
instructions are SSA-only, it's really easy to find constants and this
isn't really needed anymore.

Second, in the case where we are doing a self-mov of a register, we delete
those channels that are moved to themselves from the write-mask.  This

i965: Make sure we blit a full compressed block

This fixes an assertion failure in [at least] one of the Unreal Engine Linux
demo/games that uses DXT1 compression. Specifically, the "Vehicle Game".

At some point, the game ends up trying to blit mip level whose size is 2x2,
which is smaller than a DXT1 block. As a result, the assertion in the blit path
is triggered. It should be safe to simply make sure we align the width and
height, which is sadly an example of compression being less efficient.

i965: Apply VS attribute workarounds in NIR.

Instead of emitting shader code in the vec4 backend, we now simply
call a NIR pass to emit the necessary code.

This simplifies the vec4 backend.  Beyond deleting code, it removes
the primary use of ATTR as a destination.  It also eliminates the
requirement that the vec4 VS backend express the ATTR file in terms
of VERT_ATTRIB_* locations, giving us a bit more flexibility.

This approach is a little different: rather than munging the attributes
at the top, we emit code to fix them up when they're accessed.  However,
we run the optimizer afterwards, so CSE should eliminate the redundant
math.  It may even be able to fuse it with other calculations based on
the input value.

shader-db does not handle non-default NOS settings, so I have no
statistics about this patch.

Note that the scalar backend does not implement VS attribute
workarounds, as they are unnecessary on hardware which allows SIMD8 VS.

mesa/readpix: Clip ReadPixels() area to the ReadBuffer's

the specified area to a valid one. Rather than clip in various
corner-cases, perform this operation in the API validation stage.

The bug in intel_readpixels_tiled_memcpy() showed itself when the winsys
ReadBuffer's height was smaller than the one specified by ReadPixels().
yoffset became negative, which was an invalid input for tiled_to_linear().

and leaves the sampler deref alone as it did before and nir_lower_samplers
assumes this.  Backends can still assume that they are combined and only
look at only at the texture index.  Or, if they wish, they can assume that
they are separate because nir_lower_samplers, tgsi_to_nir, and prog_to_nir
all set both texture and sampler index whenever a sampler is required (the
two indices are the same in this case).

i965: Explicitly write the "TR DS Cache Disable" bit at TCS EOT.

Bit 0 of the Patch Header is "TR DS Cache Disable".  Setting that bit
disables the DS Cache for tessellator-output topologies resulting in
stitch-transition regions (but leaves it enabled for other cases).

We probably shouldn't leave this to chance - the URB could contain
garbage - which could result in the cache randomly being turned on
or off.

This patch makes the final EOT write 0 to the first DWord (which
only contains this one bit).  This ensures the cache is always on.
