From: Hans de Goede Date: Fri, 22 Apr 2016 12:26:50 +0000 (+0200) Subject: tgsi: Add WORK_DIM System Value X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d386cef246b5949a1199f3b9d53a9e6d125e4869;p=mesa.git tgsi: Add WORK_DIM System Value Add a new WORK_DIM SV type, this is will return the grid dimensions (1-4) for compute (opencl) kernels. This is necessary to implement the opencl get_work_dim() function.
