Until now there has been only one type of color buffer that needs
to resolved - namely single sampled fast clear. As even the
sampler engine in GPU doesn't understand the associated meta data,
the color values need to be always resolved prior to reading them.
From SKL onwards there is new scheme supported called the lossless
compression of single sampled color buffers. This is something that
is understood by the sampling engine and therefore resolving of
these types of buffers is not necessary before sampling.
This patch adds means to make the distinction when considering if
resolve is needed.

In addition to simply calling miptree_create() the higher level
call intel_miptree_create() also considers if the buffer should
be associated with an auxiliary buffer based on the given format.
Here we are allocating an auxiliary buffer which in turn has such
format that would mislead intel_miptree_create_layout() later on
to try to associate the auxiliary buffer with an auxiliary buffer.
To prevent this the actual buffer creation logic was split out
into its own function. Lets invoke that instead.

The L3 partitioning code tries to look at all programs - both render
programs (VS/TCS/TES/GS/FS) and compute (CS).
After calling brw_clear_cache, all prog_data pointers are invalid and
point to freed data. The intention was that flagging the dirty bits for
all programs would cause the next draw call to re-run the atoms for each
program stage, uploading new programs and installing new, valid pointers.
However, this doesn't quite work in our new multi-pipeline world. When
drawing or dispatching a compute workload, we only consider the programs
for the appropriate pipeline: drawing sets up VS/TCS/TES/GS/FS, but not
CS, and vice versa. This leaves pointers dangling a bit longer than
intended.
The L3 configuration code tries to inspect the prog_data for all shader
stages, so that we avoid having to reconfigure it when swapping back and
forth between render and compute workloads. So we can't have dangling
pointers.
The fix is simple: have brw_clear_cache NULL out stale prog_data
pointers, making it safe to inspect. The next L3 configuration pass
will see either the render shaders or compute shader as missing for
one go around, but will pick them up when both pipelines have run.
In other words, we'll simply reconfigure L3 twice, which is safe,
if a tiny bit wasteful - but then again, we just threw every compiled
shader we had on the floor and started recompiling the from scratch,
which is massively more wasteful, so it's not much of a concern.

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.

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.

Validation may kick off copies and subsequently color resolves.

Setting brw->ctx.NewDriverState and brw->ctx.NewGLState affects
the dirty bits for the current pipeline. But, we need to flag
everything dirty on *both* pipelines, so that when we switch
back, we'll realize our programs are stale and re-upload them.
To accomplish this, flag the saved state for both pipelines.
Only one of them should matter, but this way we don't have to
check which we need to set. It's harmless to set the other.
