This mega-commit pulls most of the i965-specific bits of blorp into the
brw_blorp.c/h files which now contain nothing but i965 wrappers around
"core blorp" calls. The "core blorp" api is moved into blorp.h and the
internal blorp data structures are moved into blorp_priv.h. The new file
blorp.c is created to house "core blorp" internals which are pulled from
the old brw_blorp.c

The helpers are completely miptree-unaware and each fairly cleanly do a
single thing. This does come at the downside of not doing proper debug
reporting on whether or not we're doing replicated clears.

This pulls the mcs allocation into the if statement where we initially
determine that we are doing a fast clear and moves the programming of
wm_inputs and figuring out the fast clear rect into it's own if statement.
The next commit will put code inbetween the two.

The blorp_surface_info_init call above should set the format for us and

We already have an inlined version of the function slightly higher up in
do_single_blorp_clear and all calling it does is stomp the values with the
same thing. We might as well just get rid of it.

Now that we have the brw_blorp_surf struct, we can start to make bits of
blorp completely miptree-unaware. To start things off, we split the guts
of brw_blorp_blit_miptrees into a brw_blorp_blit function which knows
nothing about miptrees.

At the moment, this seems to make all of the interfaces messier rather than
clener. However, it does provide a representation of a surface that
simultaneously contains everything and is completely unaware of miptrees.

The isl_surf munging doesn't happen until fairly late in the blorp_blit

This keeps all of the nastyness of gen6 stencil on the i965 side of the API
line and lets us delete that nasty hand-rolled ISL-based offset path that

This commit also adds support for an offset for aux surfaces. In GL, this
only gets used for HiZ on SNB at the moment. However, in Vulkan, all aux
surfaces are at a non-zero offset and that is likely to happen in GL
eventually.

This commit movies us from a miptree model to a surf+bo+offset model. In
the GL driver, miptrees are almost always at the start of the bo so the
offset is zero but we don't want to always make that assumption. In the
sort term, gen6 stencil and HiZ will be at an offset but, in the long term,
any Vulkan surface is liable to be at a non-zero offset.

The previous HiZ support was bogus because all of get_aux_isl_surf looked
at mt->mcs_mt directly. For HiZ buffers, you need to look at either
mt->hiz_buf or mt->hiz_buf->mt.

Otherwise, the clear color will get ignored. This prevents assertion

In order for the calculations of things such as fast clear rectangles to
work, we need more details of the auxiliary surface to be correct. In
particular, we need to be able to trust the width and height fields.
(These are not necessarily what you want coming out of the miptree.) The
only values state setup really cares about are the row and array pitch and
those we can safely stomp from the miptree.

Since the dawn of time, blorp has used offsets directly to get at different
mip levels and array slices of surfaces. This isn't really necessary since
we can just use the base level/layer provided in the surface state. While
it may have simplified blorp's original design, we haven't been using the
blorp path for surface state on gen8 thanks to render compression and
there's really no good need for it most of the time. This commit restricts
such surface munging to the cases of fake W-tiling and fake interleaved
multisampling.

At the moment, the minify operation does nothing because
params.depth.view.base_level is always zero. However, as soon as we start
using actual base miplevels and array slices, we are going to need the
minification. Also, we only need to align the surface dimensions in the
case where we are operating on miplevel 0. Previously, it didn't matter
because it aligned on miplevel 0 and, for all other miplevels, the miptree
code guaranteed that the level was already aligned.

The sampling hardware can handle them ok. It just looks at the tiling to
determine whether it's the new gen9 1-D layout or the old one. The render
hardware isn't so smart.
