i965/vec4: fix vertical stride to avoid breaking region parameter rule
From IVB PRM, vol4, part3, "General Restrictions on Regioning Parameters": "If ExecSize = Width and HorzStride ≠ 0, VertStride must be set to Width * HorzStride." In next patch, we are going to modify the region parameter for uniforms and vgrf. For uniforms that are the source of DF align1 instructions, they will have <0, 4, 1> regioning and the execsize for those instructions will be 4, so they will break the regioning rule. This will be the same for VGRF sources where we use the vstride == 0 exploit. As we know we are not going to cross the GRF boundary with that execsize and parameters (not even with the exploit), we just fix the vstride here. v2: - Move is_align1_df() (Curro) - Refactor exec_size == width calculation (Curro) Signed-off-by: Samuel Iglesias Gonsálvez <[email protected]> Cc: "17.1" <[email protected]> Reviewed-by: Francisco Jerez <[email protected]>
