All SKL SKUs except the lowest one which has half the L3 size actually have 384K

For once, I can explain how this mistake was made and how it was missed in
review...  Historically when we enable a platform and put the production sizes,
you can simply look at the "smallest" SKU and see what its URB size is (and we
assumed it was the 1 slice variant). Since on newer platforms the URB sizes are
scaled automatically by HW, this was sufficient. On SKL, this is a bit different
as the lowest SKU actually has half of the L3 fused off. GT2 is the 1 slice (not
GT1) variant and it has 384K.

There are no Jenkins tests fixed (or regressions) and we don't expect any fixes
here because you can always run with less URB size.

i965: Turn BRW_MAX_MRF into a macro that accepts a hardware generation

There are some bug reports about shaders failing to compile in gen6
because MRF 14 is used when we need to spill. For example:
https://bugs.freedesktop.org/show_bug.cgi?id=86469
https://bugs.freedesktop.org/show_bug.cgi?id=90631

Discussion in bugzilla pointed to the fact that gen6 might actually have
24 MRF registers available instead of 16, so we could use other MRF
registers and avoid these conflicts (we still need to investigate why
some shaders need up to MRF 14 anyway, since this is not expected).

Notice that the hardware docs are not clear about this fact:

SNB PRM Vol4 Part2's "Table 5-4. MRF Registers Available in Device
Hardware" says "Number per Thread" - "24 registers"

However, SNB PRM Vol4 Part1, 1.6.1 Message Register File (MRF) says:

"Normal threads should construct their messages in m1..m15. (...)
Regardless of actual hardware implementation, the thread should
not assume th at MRF addresses above m15 wrap to legal MRF registers."

Therefore experimentation was necessary to evaluate if we had these extra
MRF registers available or not. This was tested in gen6 using MRF
registers 21..23 for spilling and doing a full piglit run (all.py) forcing
spilling of everything on the FS backend. It was also tested by doing
spilling of everything on both the FS and the VS backends with a piglit run
of shader.py. In both cases no regressions were observed. In fact, many of
these tests where helped in the cases where we forced spilling, since that
triggered the same underlying problem described in the bug reports. Here are
some results using INTEL_DEBUG=spill_fs,spill_vec4 for a shader.py run on
gen6 hardware:

Using MRFs 13..15 for spilling:
crash: 2, fail: 113, pass: 6621, skip: 5461

Using MRFs 21..23 for spilling:
crash: 2, fail: 12, pass: 6722, skip: 5461

using MRF registers 21..23 in gen6.

we have the hardware generation available.

Ken suggested to add the asserts to brw_set_src0 and brw_set_dest since that
would make sure that we catch all uses of MRF registers, even those coming

i965: Maximum allowed size of SEND messages is 15 (4 bits)

Until now we only used MRFs 1..15 for regular SEND messages, so the
message length could not possibly exceed the maximum size. Soon we'll
allow to use MRF registers 1..23 in gen6, so we need to be careful
not to build messages that can go beyond the limit. That could occur,
specifically, when building URB write messages, which we may need to
split in chunks due to their size. Previously we would simply go and
create a new message when we reached MRF 13 (since 13..15 were
reserved for spilling), now we also want to check the size of the
message explicitly.

Besides adding that condition to split URB write messages properly,
this patch also adds asserts in the generator. Notice that
brw_inst_set_mlen already asserts for this, but asserting in the
generators is easy and can make debugging easier in some cases.

9 years agoglsl: order indices for samplers inside a struct array

glsl: order indices for samplers inside a struct array

This allows the correct offset to be easily calculated for indirect
indexing when a struct array contains multiple samplers, or any crazy
nesting.

The indices for the folling struct will now look like this:
Sampler index: 0 Name: s[0].tex
Sampler index: 1 Name: s[1].tex
Sampler index: 2 Name: s[0].si.tex
Sampler index: 3 Name: s[1].si.tex
Sampler index: 4 Name: s[0].si.tex2
Sampler index: 5 Name: s[1].si.tex2

Before this change it looked like this:
Sampler index: 0 Name: s[0].tex
Sampler index: 3 Name: s[1].tex
Sampler index: 1 Name: s[0].si.tex
Sampler index: 4 Name: s[1].si.tex
Sampler index: 2 Name: s[0].si.tex2
Sampler index: 5 Name: s[1].si.tex2

   sampler2D tex;
   sampler2D tex2;

   sampler2D tex;
   S_inner si;

uniform S s[2];
