i965: Use prepare_external instead of make_shareable in setTexBuffer2
The setTexBuffer2 hook from GLX is used to implement glxBindTexImageEXT
which has tighter restrictions than just "it's shared". In particular,
it says that any rendering to the image while it is bound causes the
contents to become undefined. This means that we can do whatever aux
tracking we want between glxBindTexImageEXT and glxReleaseTexImageEXT so
long as we always transition from external in Bind and to external in
Release.
The fact that we were using make_shareable before was a problem because
it would resolve away 100% of the aux data and then throw away our
reference to the aux buffer. If the aux data was shared with some other
application (i.e. if we're using I915_FORMAT_MOD_Y_TILED_CCS) then we
would forget that the aux data even existed for the rest of eternity.
This is fine for the first frame but any subsequent calls to
glxBindTexImageEXT would bind the texture as if it has no aux
whatsoever and no resolves would happen and texturing would happen as if
there is no aux. This was causing rendering corruption in mutter when
running on top of X11 with modifiers.

i965/tex_image: Reference the renderbuffer miptree in setTexBuffer2
The old code made a new miptree that referenced the same BO as the
renderbuffer and just trusted in the memory aliasing to work. There are
only two ways in which the new miptree is liable to differ from the one
in the renderbuffer and neither of them matter:
1) It may have a different target. The only targets that we can ever
see in intelSetTexBuffer2 are GL_TEXTURE_2D and GL_TEXTURE_RECTANGLE
and the difference between the two doesn't matter as far as the
miptree is concerned; genX(update_sampler_state) only looks at the
gl_texture_object and not the miptree when determining whether or
not to use normalized coordinates.
2) It may have a very slightly different format. Again, this doesn't
matter because we've supported texture views for quite some time so
we always look at the gl_texture_object format instead of the
miptree format for hardware setup anyway.
On the other hand, because we were recreating the miptree, we were using
intel_miptree_create_for_bo which doesn't understand modifiers. We
really want this function to work without doing a resolve so long as you
have modifiers so we need to fix that.

i965: emit BRW_NEW_AUX_STATE on aux state changes
Fixes a regression introduced with
b96313c0e1289b296d7, which removed
BRW_NEW_BLORP for a bunch of SURFACE_STATE setup code, including render
targets, on the basis that blorp invalidates binding tables but not
surface states, however, at least on Broadwell, this caused a regression
in a CTS test, which Ken and Jason tracked down to the fact that we
are not uploading new render target surface states after allocating
new CCS_D surfaces for fast clears (which allocation is deferred until
an actual clear occurs).
The reason this only fails in BDW is that on SKL+ we use CCS_E which
is allocated up front so it exists in the initial surface state, the
problem can be reproduced in these platforms too if we use
INTEL_DEBUG=norcb to force the CCS_D path.
This patch, together with the ones preceding it, fixes the regression
by ensuring that we track and flag as dirty all aux state changes.

regression.

With this change, we also need to update our "are we near the end?"

these estimates by looking at the size of draw calls in the Unreal 4
Elemental Demo (using INTEL_DEBUG=flush and always_flush_batch=true).
This will significantly impact the size of our batches. I've adjusted

right, but we may need to adjust this further. I tried a 16kB batch,

Growing is fairly straightforward:
1. Allocate a new larger BO.
2. memcpy the existing contents over to the new buffer
3. Set the new BO to the same GTT offset as the old BO. When emitting
relocations, we write the presumed GTT offset of the target BO. If
we changed it, we'd have to update all the existing values (by
walking the relocation list and looking at offsets), which is more
expensive. With the old BO freed, ideally the kernel could simply
place the new BO at that offset anyway.
4. Update the validation list to contain the new BO.
5. Update the relocation list to have the GEM handle for the new BO
(which we can skip if using I915_EXEC_HANDLE_LUT).

i965: Use a separate state buffer, but avoid changing flushing behavior.
Previously, we emitted GPU commands and indirect state into the same
buffer, using a stack/heap like system where we filled in commands from
the start of the buffer, and state from the end of the buffer. We then
flushed before the two met in the middle.
Meeting in the middle is fatal, so you have to be certain that you
reserve the correct amount of space before emitting commands or state
for a draw. Currently, we will assert !no_batch_wrap and die if the
estimate is ever too small. This has been mercifully obscure, but has
happened on a number of occasions, and could in theory happen to any
application that issues a large draw at just the wrong time.
Estimating the amount of batch space required is painful - it's hard to
get right, and getting it right involves a lot of code that would burn
CPU time, and also be painful to maintain. Rolling back to a saved
state and retrying is also painful - failing to save/restore all the
required state will break things, and redoing state emission burns a
lot of CPU. memcpy'ing to a new batch and continuing is painful,
because commands we issue for a draw depend on earlier commands as well
(such as STATE_BASE_ADDRESS, or the GPU being in a pirtacular state).
The best plan is to never run out of space, which is totally doable but
pretty wasteful - a pessimal draw requires a huge amount of space, and
rarely occurs. Instead, we'd like to grow the batch buffer if we need
more space and can't safely flush.
We can't grow with a meet in the middle approach - we'd have to move the
state to the end, which would mean updating every offset from dynamic
state base address. Using separate batch and state buffers, where both
fill starting at the beginning, makes it easy to grow either as needed.
This patch separates the two concepts. We create a separate state
buffer, with a second relocation list, and use that for brw_state_batch.
However, this patch tries to retain the original flushing behavior - it
adds the amount of batch and state space together, as if they were still
co-existing in a single buffer. The hope is to flush at the same time
as before. This is necessary to avoid provoking bugs caused by broken
batch wrap handling (which we'll fix shortly). It also avoids suddenly
increasing the size of the batch (due to state not taking up space),
which could have a significant performance impact. We'll tune it later.
v2:
- Mark the statebuffer with EXEC_OBJECT_CAPTURE when supported (caught
by Chris). Unfortunately, we lose the ability to capture state data
on older kernels.
- Continue to support the malloc'd shadow buffers.
