[Mesa-dev] [PATCH v2 00/15] Add ARB_vertex_attrib_64bit for i965 scalar (gen8+)

[Antia Puentes]

Hello,

the following series is a resend of the implementation for the
ARB_vertex_attrib_64bit extension on the i965 scalar backend (gen8+).

This resend includes all the feedback received to v1 plus:

 * Minor changes after rebasing the series against the updated version
    of the arb_gpu_shader_fp64 extension, that is being reviewed on the
       list too right now. Those changes were basically adapt our function
          calls after changes on their signatures, and a retype of the dest
             register when shufling (patch 05)

 * Two new patches, to handle properly the linking, as agreed with
    Kenneth Graunke on this email [1]. Those two are the only ones
       totally unreviewed right now:

     [PATCH 11/15] glsl/linker: dvec3/dvec4 may consume twice input vertex attributes
          [PATCH 12/15] dri/i965: dvec3/dvec4 consume twice input vertex attributes

Again, as this work depends on the ARB_gpu_shader_fp64 i965
functionality [2], 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 branch containing the fp64 patches + the
series is available in our repo:

$ git clone -b i965-attrib64-v2 https://github.com/Igalia/mesa.git
