Mike Blumenkrantz	9ca0c0b4b4	mesa/st: increment num_uniforms for hw accel select shaders ... this otherwise breaks nir_lower_uniforms_to_ubo() and probably lots of drivers Fixes: 9b22ab4167 ("mesa/st: implement hardware accelerated GL_SELECT") Reviewed-by: Qiang Yu <yuq825@gmail.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/17092>	2022-06-18 20:18:18 +00:00
Qiang Yu	9b22ab4167	mesa/st: implement hardware accelerated GL_SELECT ... Use an internal geometry shader to handle input primitives. Do full accurate culling and clipping in the shader and output hit result and min/max depth to a SSBO for final being written to select buffer. With multiple result slots in SSBO we can left multiple draws on the fly and wait them done when buffer is full or exit GL_SELECT mode. This provides quicker selection response compared to software based solution. Tested on Discovery Studio 2020: some complex model needs 1~2s selection response time originally, now it's almost selected immidiately.
