The slightly less mechanical change of converting the emit_reloc calls
will follow.

|
This will help in bufmgr debugging and aub dumping.
|
|
We could potentially do this on G45 as well, though the units are
different. On 965, the timestamp is tied to hclk, which would make
supporting it harder.

We should be able to do 16, but are limited by Mesa's static buffer
allocations.
|
|
If you used all 4 color targets we currently support, we would see 0
and end up just writing the first output. Give enough bits that we
can do the maximum of 16.
Fixes piglit fbo-drawbuffers-maxtargets.

The idea would be that you could have multiple send messages going on
if nothing depended on the previous message's results and you used a
different send message. The problem is that the later send requires
the VUE handle returned by the first send's allocate anyway.

This basically restores the previous state, where a vertex result slot
is set up for the texcoord to be replaced with point coord. Fixes
piglit point-sprite test.

This is trying to follow the spirit of the invariance rules, though
they're not specific on this point. Fixes quad-invariance piglit test
while retaining the 22s -> 18s win on glean blendFunc.
This was a regression in c67d9d84f501f145f841c0b981caff6f4dfd936f.

GL doesn't actually let you begin an OQ while one is active, so the
extra work was pointless.

Bug #24470: glean clipFlat test.
|
|
|
|
|
|
The RGBX version isn't supported as a vertex input type, but since we
force the last channel's value anyway, this should be fine. The only
potential risk I see is in the limiter on VBO reads past the end of
the buffer forcing the whole vertex to 0 when the A channel lands past
the end.
Fixes piglit draw-vertices-half-float.

This is similar to the GL_QUAD_STRIP -> TRIANGLE_STRIP optimization --
the GS usage to split the quads into tris is a huge bottleneck, so a
quick check improves glean blendFunc time massively (width * height of
the window of single-pixel GL_QUADS, many many times). This may also
end up helping with cairo performance, which sometimes ends up drawing
a single quad.

Rename old IGDNG to Ironlake, and set 'gen' number for
Ironlake as 5, so tracking the features with generation num
instead of special is_ironlake flag.

Most of the failure from using uninlined function calls ends up being
just bad rendering, but nested function calls in the VS currently hang
the GPU, so reject them and explain why.
|
|
We were doubling up the offsets for the mipmap levels for CPU access.
Instead of reimplementing i945_miptree_layout_2d with 6 cube images
separated by qpitch, share that function and provide the level offsets
later.
Fixes piglit cubemap and fbo-cubemap.

This should be functionally equivalent, with the possible exception of
NaN handling.

|
We could use this to reduce constant register pressure, but for now it
makes the resulting program assembly much more readable.

|
This struct is used to generate a hash, ignoring the entry boundaries.

Fixes assertion failure in fbo-generatemipmap-npot.

We would run into trouble due to the hardware using inclusive numbers
and the subtraction to handle that producing negative (meaning large
positive) coordinates.

Rejecting all doesn't seem to be helping get the pipeline lit up.
|
|
|
|
|
|
It appears that the thing that was killing VS threads was the
gratuitous NOP that replaced the gratuitous jump from OPCODE_END to
the nearby OPCODE_END implementation. With that gone, we can move on
to the rest of the pipeline.
|
|
Just emit the URB write at END time. Subroutine code that sits after
OPCODE_END won't be executed since we've ended the thread at the point
that the URB write is done.
|
|
Otherwise, we may not get the FFTID set up which would break freeing
of resources.
|
|
The hope is to later take advantage of the reduced constant usage to
free up regs. This only covers the GLSL path at the moment, because
the brw_wm_emit path doesn't get the information as to whether a float
value is a constant or a uniform.
|
|
I keep finding the desire to force this path to debug it instead of
cooking up goofy-looking testcases to do so.
|
|
Tested with piglit glsl-fs-sqrt-branch, fp-cmp.vpfp.
|
|
The pitch is not really an inherent part of the miptree, since it's
not part of any of the layout calculations, and it's dictated by the
libdrm-allocated region pitch now.
