ctx->last_fence isn't such a terribly clever idea, if batches can be

created before the batch is flushed (useful for next patch), that later
gets populated after the batch is actually flushed.

broadcom/vc4: Use a single-entry cached last_hindex value.

Since almost all BOs will be in one CL at a time, this cache will almost
always hit except for the first usage of the BO in each CL.

This didn't show up as statistically significant on the minetest trace
(n=340), but if I lop off the throttled lobe of the bimodal distribution,
it very clearly does (0.74731% +/- 0.162093%, n=269).

broadcom/vc4: Decompose single QUADs to a TRIANGLE_FAN.

No significant difference in the minetest replay, but it should reduce
overhead by not requiring that we write quad indices to index buffers that
we repeatedly re-upload (and making the draw packet smaller, as well).

Over the course of the series the actual game seems to be up by 1-2 fps.

broadcom/vc4: Use the new enum functionality of the XML to decode better.

broadcom/vc4: Skip emitting redundant VC4_PACKET_GEM_HANDLES.

Now that there's only one user of it, it's pretty obvious how to avoid
emitting redundant ones.  This should save a bunch of kernel validation
overhead.

No statistically sigificant difference on the minetest trace I was looking
at (n=169), but the maximum FPS is up by .3%

broadcom/vc4: Simplify the relocation handling for index buffers.

Originally there was CL code for handling various relocations back when I
had relocs for the TSDA/TA buffers.  Now that the kernel handles those
entirely on its own, I can inline that code into the one place using it.

broadcom/vc4: Fix handling of GFXH-515 workaround with a start vertex count.

We failed to take the start into account for how many vertices to draw in
this round, so we would end up decrementing count below 0, which as an
unsigned number meant we would loop until the CLs soon ran out of space.

When I wrote the code I was thinking about how to use the previously
emitted shader state (no index bias baked into the elements) by emitting
up to 65535 and then only re-emitting with bias for the second wround, but
that doesn't work if the start is over 65535.  Instead, just delay
emitting shader state until we get into the drawarrays GFXH-515 loop and
always bake the bias in when we're doing the workaround.

broadcom/vc4: Fix the scaling factor for the GFXH-515 workaround.

For triangle strips, we step by max_verts - 2.

i965/vec4: use a temp register to compute offsets for pull loads

64-bit pull loads are implemented by emitting 2 separate
32-bit pull load messages, where the second message loads from
an offset at +16B.

That addition of 16B to the original offset should not alter the

though, since the compiler might use that same offset register in other

that take that same offset as reference).

If the pull load is 32-bit then we only need to emit one message and
we don't need to do offset calculations, but in that case the optimizer
should be able to drop the redundant MOV.

etnaviv: GC7000: Factor out state based texture functionality

Prepare for two texture handling paths, the descriptor-based
path will be added in a future commit. These are structured
so that the texture implementation handles its own state
emission.

etnaviv: Use only DRAW_INSTANCED on GC3000+

The blob does this, as DRAW_INSTANCED can replace fully all the other
draw commands. It is also required to handle integer vertex formats.
The other path is only there for compatibility and might go away (or at
least rot to become buggy due to dis-use) in newer hardware.

As a by-effect this changes the behavior for GC3000-, by no longer using
the index offset for DRAW_INDEXED but instead adding it to INDEX_ADDR.
This should make no difference.

i965: Reorganize batch/state BO fields into a 'brw_growing_bo' struct.

We're about to add more of them, and need to pass the whole lot of them
around together when growing them.  Putting them in a struct makes this
much easier.

brw->batch.batch.bo is a bit of a mouthful, but it's nice to have things
labeled 'batch' and 'state' now that we have multiple buffers.

i965: Don't grow batch/state buffer on every emit after an overflow.

Once we reach the intended size of the buffer (BATCH_SZ or STATE_SZ), we
try and flush.  If we're not allowed to flush, we resort to growing the
buffer so that there's space for the data we need to emit.

We accidentally got the threshold wrong.  The first non-wrappable call
beyond (e.g.) STATE_SZ would grow the buffer to floor(1.5 * STATE_SZ),
The next call would see we were beyond STATE_SZ and think we needed to
grow a second time - when the buffer was already large enough.

We still want to flush when we hit STATE_SZ, but for growing, we should
use the actual size of the buffer as the threshold.  This way, we only
grow when actually necessary.

i965: Use old_bo->align when growing batch/state buffer instead of 4096.

The intention here is make the new BO use the same alignment as the old
BO.  This isn't strictly necessary, but we would have to update the
'alignment' field in the validation list when swapping it out, and we
don't bother today.

The batch and state buffers use an alignment of 4096, so this should be
equivalent - it's just clearer than cut and pasting a magic constant.

i965: Program the dynamic state heap size to MAX_STATE_SIZE.

STATE_BASE_ADDRESS specifies a maximum size of the dynamic state
section, beyond which data supposedly reads back as 0.  On Gen8+,
we were programming it to the size of the buffer.  This worked fine
until we started growing the state buffer in commit 2dfc119f22f25708.
When the state buffer grows, the value in STATE_BASE_ADDRESS becomes
too small, and our state beyond STATE_SZ bytes would read back as 0.

To avoid having to update the value, we program it to MAX_STATE_SIZE.
We used to program the upper bound to the maximum on older hardware
anyway, so programming it too large isn't a big deal.

Bogus SURFACE_STATE can easily lead to GPU hangs and misrendering.
DiRT Rally was hitting the statebuffer growth path, and suffered from
bad texture corruption and GPU hangs (usually around the same time).

This patch fixes both issues.
