Hi, This series implements the support for Haswell 64bit vertex attributes. With it, we can enable OpenGL 4.2 in Haswell.
This work covers partially https://bugs.freedesktop.org/show_bug.cgi?id=94442. These patches are available in our repository for testing. You can clone it using the following command: $ git clone -b i965-va64-gen7-scalar-vec4-rc1 https://github.com/Igalia/mesa.git The main differences between the previous work[0] and this one is that in this case the support is done in the align16 backend. Regards, J.A.
