9 years agomesa: Delete VAO _MaxElement code and index buffer bounds checking.

mesa: Delete VAO _MaxElement code and index buffer bounds checking.

Fredrik's implementation of ARB_vertex_attrib_binding introduced new
gl_vertex_attrib_array and gl_vertex_buffer_binding structures, and
converted Mesa's older gl_client_array to be derived state.  Ultimately,
we'd like to drop gl_client_array and use those structures directly.

One hitch is that gl_client_array::_MaxElement doesn't correspond to
either structure (unlike every other field), so we'd have to figure out
where to store it.  The _MaxElement computation uses values from both
structures, so it doesn't really belong in either place.  We could put
it in the VAO, but we'd have to pass it around everywhere.

It turns out that it's only used when ctx->Const.CheckArrayBounds is
set, which is only set by the (rarely used) classic swrast driver.
It appears that drivers/x11 used to set it as well, which was intended
to avoid segmentation faults on out-of-bounds memory access in the X
server (probably for indirect GLX clients).  However, ajax deleted that
code in 2010 (commit 1ccef926be46dce3b6b5c76e812e2fae4e205ce7).

The bounds checking apparently doesn't actually work, either.  Non-VBO
attributes arbitrarily set _MaxElement to 2 * 1000 * 1000 * 1000.
vbo_save_draw and vbo_exec_draw remark /* ??? */ when setting it, and
the i965 code contains a comment noting that _MaxElement is often bogus.

Given that the code is complex, rarely used, and dubiously functional,
it doesn't seem worth maintaining going forward.  This patch drops it.

This will probably mean the classic swrast driver may begin crashing on
out of bounds vertex buffer access in some cases, but I believe that is
allowed by OpenGL (and probably happened for non-VBO accesses anyway).
There do not appear to be any Piglit regressions, either.

util: Add big-endian layout for a number of formats.

This patch builds on 6c8f547f66e68b495c708f8ffcb67370caa5ffe8 and
previous patches by allowing u_format.csv to specify separate big-endian
and little-endian layouts.  It then uses this to specify the correct layouts
for various depth/stencil formats.  Later patches handle other formats.

To recap, the idea is that u_format.csv lists the channels for an N-byte
value as though it were an N-byte integer.  For little-endian targets
the channels are listed starting at the least-significant bit of the
integer while for big-endian targets the channels are listed starting
at the most-significant bit.  This means that for something like
PIPE_FORMAT_B8G8R8A8_UNORM (blue in first byte of memory, alpha in last
byte of memory) the orders are the same for both endiannesses.  But for
something like PIPE_FORMAT_S8_UINT_Z24_UNORM, where the stencil is in
the least significant byte of a 32-bit integer, there need to be separate
channel definitions for each endianness.

The effect of this patch is to make the affected PIPE_FORMAT_*s have
the same layout as the associated MESA_FORMAT_*s for big-endian.
The MESA_FORMAT_*s are already handled correctly.

Fixes various piglit tests on z.  No regressions on x86_64.

llvmpipe treats PIPE_FORMAT_Z32_FLOAT_S8X24_UINT as a bit of a special case,
handling it as two 32-bit pieces rather than a single 64-bit block:

   /* 64bit d/s format is special already extracted 32 bits */
   total_bits = format_desc->block.bits > 32 ? 32 : format_desc->block.bits;

The format_desc describes the whole 64-bit block, so the z shift
will be 32 for big-endian.  But since we're accessing the z channel
as a 32-bit value rather than a 64-bit value, we need to mask the shift

glsl: Speed up constant folding for swizzles.

ir_rvalue::constant_expression_value() recursively walks down an IR
tree, attempting to reduce it to a single constant value.  This is
useful when you want to know whether a variable has a constant
expression value at all, and if so, what it is.

The constant folding optimization pass attempts to replace rvalues with
their constant expression value from the bottom up.  That way, we can
optimize subexpressions, and ideally stop as soon as we find a
non-constant subexpression.

In order to obtain the actual value of an expression, the optimization
pass calls constant_expression_value().  But it should only do so if it
knows the value can be combined into a constant.  Otherwise, at each
step of walking back up the tree, it will walk down the tree again, only
to discover what it already knew: it isn't constant.

We properly avoided this call for ir_expression nodes, but not for
ir_swizzle nodes.  This patch fixes that, drastically reducing compile
times on certain shaders where tree grafting has given us huge
expression trees.  It also fixes SuperTuxKart.

Thanks to Iago and Mike for help in tracking this down.

freedreno: "fix" problems with excessive flushes

4f338c9b introduced logic to trigger a flush rather than overflowing
cmdstream buffer.  But the threshold was too low, triggering flushes
where they were not needed.  This caused problems with games like
xonotic.

Part of the problem is that we need to mark all state dirty between
cmdstream submit ioctls, because we cannot rely on state being
preserved across ioctls.  But even with that, there are still some
problems that are still being debugged.  For now:

1) correctly mark all state dirty
2) introduce FD_MESA_DEBUG flush flag to force rendering to be flushed
between each draw, to trigger problems (so that I can debug)
3) use a more reasonable threshold so for normal usecases we don't
trigger the problems

This at least corrects the regression, but there is still more debugging
to do.
