From the OpenGL 4.5 specification, Section 17.4.1 "Selecting Buffers

 "An INVALID_ENUM error is generated if any value in bufs is FRONT,

  the de- fault framebuffer and framebuffer objects, and exists
  because these constants may themselves refer to multiple buffers, as
  shown in table 17.4."

And on page 492 (page 514 of the PDF):
 "If the default framebuffer is affected, then each of the constants

Kenneth Graunke [Tue, 29 Nov 2016 00:59:45 +0000 (16:59 -0800)]
i965: Fix number of slots in SSO mode when there are no user varyings.

We want vue_map->num_slots to be one more than the final slot.

When assigning fixed slots, built-in slots, and non-SSO user varyings,
we do slot++.  This leaves "slot" as one past the most recently assigned
slot.  But for SSO user varyings, we computed slot based on the varying
location value...and left it at that slot value.

To work around this inconsistency, I made num_slots be "slot + 1" if
separate and "slot" otherwise.  The problem is...if there are no user
varyings in SSO mode...then we would have done slot++ when assigning
built-ins, so it would be off by one.  This resulted in loops from 0
to vue_map->num_slots hitting a bonus BRW_VARYING_SLOT_PAD at the end.

This used to break the SIMD8 VS/TES backends, but I fixed that in
commit 480d6c1653713dcae617ac523b2ca5deee01c845.  It's probably safe
at this point, but we should fix it anyway.

To fix this, do slot++ in all cases.  For SSO mode, we overwrite slot
for every varying, so this increment only matters on the last varying.
Because we process varyings in order, this will set slot to 1 more
than the highest assigned slot.

7 years agonir/i965: use two slots from inputs_read for dvec3/dvec4 vertex input attributes
Juan A. Suarez Romero [Fri, 16 Dec 2016 09:24:43 +0000 (10:24 +0100)]
nir/i965: use two slots from inputs_read for dvec3/dvec4 vertex input attributes

So far, input_reads was a bitmap tracking which vertex input locations
were being used.

In OpenGL, an attribute bigger than a vec4 (like a dvec3 or dvec4)
consumes just one location, any other small attribute. So we mark the
proper bit in inputs_read, and also the same bit in double_inputs_read
if the attribute is a dvec3/dvec4.

But in Vulkan, this is slightly different: a dvec3/dvec4 attribute
consumes two locations, not just one. And hence two bits would be marked
in inputs_read for the same vertex input attribute.

To avoid handling two different situations in NIR, we just choose the
latest one: in OpenGL, when creating NIR from GLSL/IR, any dvec3/dvec4
vertex input attribute is marked with two bits in the inputs_read bitmap
(and also in the double_inputs_read), and following attributes are
adjusted accordingly.

As example, if in our GLSL/IR shader we have three attributes:

layout(location = 0) vec3  attr0;
layout(location = 1) dvec4 attr1;
layout(location = 2) dvec3 attr2;

then in our NIR shader we put attr0 in location 0, attr1 in locations 1
and 2, and attr2 in location 3 and 4.

Checking carefully, basically we are using slots rather than locations
in NIR.

When emitting the vertices, we do a inverse map to know the
corresponding location for each slot.

v2 (Jason):
- use two slots from inputs_read for dvec3/dvec4 NIR from GLSL/IR.

v3 (Jason):
- Fix commit log error.
- Use ladder ifs and fix braces.
- elements_double is divisible by 2, don't need DIV_ROUND_UP().
- Use if ladder instead of a switch.
- Add comment about hardware restriction in 64bit vertex attributes.

isl: fix VA64 support for double and dvecN vertex attributes

to avoid conversions. From the BDW PRM, Volume 2d, page 586
(VERTEX_ELEMENT_STATE):

     "When SourceElementFormat is set to one of the *64*_PASSTHRU
     formats, 64-bit components are stored in the URB without any
     conversion. In this case, vertex elements must be written as 128
     or 256 bits, with VFCOMP_STORE_0 being used to pad the output
     as required. E.g., if R64_PASSTHRU is used to copy a 64-bit Red
     component into the URB, Component 1 must be specified as
     VFCOMP_STORE_0 (with Components 2,3 set to VFCOMP_NOSTORE)
     in order to output a 128-bit vertex element, or Components 1-3 must
     be specified as VFCOMP_STORE_0 in order to output a 256-bit vertex
     element. Likewise, use of R64G64B64_PASSTHRU requires Component 3
     to be specified as VFCOMP_STORE_0 in order to output a 256-bit vertex
     element."
