Subject: llvmpipe: enable PIPE_CAP_TGSI_VS_LAYER_VIEWPORT
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=763fc526c73bb7e3c7e2733106ad259f7dbd45f4;p=mesa.git

llvmpipe: enable PIPE_CAP_TGSI_VS_LAYER_VIEWPORT

No changes required in the driver itself, all handled by draw.

piglit results in a quick run:
skip->pass 7
skip->fail 2
(The new failures in the ARB_fragment_layer_viewport group are expected,
we fail the same if gs doesn't write these outputs regardless of the vs.)
