If the application has requested reset notification, then
dri2_convert_glx_attribs will initialize this to the correct value.
Otherwise, it's supposed to initialize this to NO_NOTIFICATION, but
doesn't when num_attribs == 0. (The consensus seems to be that we
should make it do so, but that's more invasive, so I'm pushing this for
now.)

This removes the CS stall on Ivybridge.
On Sandybridge, the depth stall needs to be preceded by a non-zero
post-sync op, which requires a CS stall, which needs a stall at
scoreboard. Emit the full workaround.

I don't know if it was possible to trigger this bug -- we don't merge
saturates into the math instruction because we're bad at coalescing currently,
and there's nothing generating these with predicates. Still, let's avoid
future bugs when we do smarter codegen.
Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
This was ridiculous. We were ignoring the inst->header.saturate flag in the
case of math and only math. On gen4, we would leave inst->header.saturate in
place if it happened to be set, which would end up being applied to the
implicit mov and thus trash the first argument. On gen6, we would overwrite
inst->header.saturate with the saturate flag from the argument, which was not
set appropriately in brw_vec4_emit.cpp, and was only not a bug due to our
incompetence at coalescing saturate moves.
By ripping the argument out and making saturate work just like all the other
brw_eu_emit.c code generation, we can avoid both these classes of bugs.
Fixes piglit fog-modes, and the new specific fs-saturate-exp2 case.

There was a chance for brw_wm_emit.c to screw up and pass (1 << 4) instead of
1, which would get converted to 0 when stored. Instead, use stdbool which
converts nonzero to true/1 like we want.
Otherwise, conditional rendering always takes the fallthrough "render it
anyway" case unless the application had itself done a check or wait on the
query.

These are largely based on the src/mapi/glapi/tests. However,
shared-glapi provides less external visibility into the dispatch table,
so there is less to test. Also, shared-glapi does not implement
_glapi_get_proc_name, so that test was removed.
Signed-off-by: Ian Romanick <ian.d.romanick@intel.com>
When --enable-shared-glapi is used, all non-ABI entries in the table are
lies. Avoiding the use of glapitable.h avoids the lies. The only
entries used in this code are entries that are ABI. For these, the ABI
offset can be used directly.
Since this code is in src/glx, it can't use src/mesa/main/dispatch.h to
get the pretty names for these offsets.

When --enable-shared-glapi is used, all non-ABI entries in the table are
lies. There are two completely separate code generation paths used to
assign dispatch offset. Neither has any clue about the other.
Unsurprisingly, the can't agree on what offsets to assign.
This adds a bunch of overhead to __glXNewIndirectAPI, but this function
is called at most once.
The test ExtensionNopDispatch was removed. There was just no way to
make this test work with the information provided in shared-glapi.
Since indirect_glx.c uses _glapi_get_proc_offset now, it was also
impossible to make the tests work without shared-glapi. So much pain.
This fixes indirect rendering with shared-glapi.

PIPE_CONTROL has variable length, depending upon generation and whether
we want to do 32-bit or 64-bit data writes. Make it explicit, rather
than hiding a length of 4 in the #define for _3DSTATE_PIPE_CONTROL.
Generated by s/3DSTATE_PIPE_CONTROL/3DSTATE_PIPE_CONTROL | (4 - 2)/g.
This is equivalent since the #define used to have | 2 in it. A grep
through the sources shows that all instances have been converted, so
it's safe to remove the | 2 from the #define.

I wanted to add the surface index as a variable value for UBO support,

row, each of which would produce an oword block read of the same
block).

In between glGenBuffers() and glBindBuffer(), the buffer object points to this
dummy buffer with a name of 0, and a glBindBufferBase() would point to that.
It seems pretty clear, given that glBindBufferBase() only cares about the
current size of the buffer at render time, that it should bind up the buffer
that you passed in instead of pointing it at this useless dummy buffer.
However, what should glBindBufferRange() do? As of this patch, it will
promote the genned buffer to a proper buffer like it had been
glBindBuffer()ed, and then detect that the size is greater than the buffer's
current size of 0 and throw INVALID_VALUE. It seems like the most reasonable
answer here.
Note that this also changes the behavior of these two on non-glGenBuffers() bo
names. We haven't yet set up the error throwing for glBindBuffers() on gl
3.1+, and my assumption is that these two functions should inherit their
behavior on un-genned names from glBindBuffers().
