[Mesa-dev] [PATCH 00/15] Add ARB_vertex_attrib_64bit for i965 scalar (gen8+)

[Antia Puentes]

Hello,

the following series adds the implementation for the ARB_vertex_attrib_64bit
extension on the i965 scalar backend (gen8+). It is the result of working on
https://bugs.freedesktop.org/show_bug.cgi?id=94442.

As this work depends on the ARB_gpu_shader_fp64 i965 functionality [1],
which is work in progress, the aim of sending the series now is to get
early feedback and parallelise the review process.

The series applies on top of the current version of the
https://github.com/Igalia/mesa/tree/i965-fp64 branch,
which contains the last fp64 work for gen8.

A frozen version of the fp64 branch + the series is available in our repo:
$ git clone -b i965-attrib64-v1 https://github.com/Igalia/mesa.git

  i965: get the proper vertex surface type for doubles on gen8+
  i965: passthru formats cannot be used width edge flag enabled
  i965/fs: half exec_size when dealing with 64 bits attributes
  i965: Enable ARB_vertex_attrib_64bit for gen8+

  i965: Configure how to store *64*PASSTHRU vertex components

Juan A. Suarez Romero (8):
  i965/fs: shuffle 32bits into 64bits for doubles
  nir: add double input bitmap
  i965: take care of doubles when remapping VS attributes
  i965/vec4: use attribute slots to calculate URB read length
  i965/fs: calculate first non-payload GRF using attrib slots
  i965: take care of doubles when lowering VS inputs
  i965: abort linking if we exhaust the registers
  i965: abort linking if URB read length greater than 15
