From 1b749dc34f8d83cf3dfa863279b1fe2b356d34b2 Mon Sep 17 00:00:00 2001 From: Marek Olšák Date: Tue, 24 Apr 2012 17:31:17 +0200 Subject: gallium: add PIPE_CAP_CONSTANT_BUFFER_OFFSET_ALIGNMENT This is required for any serious constant buffer support. Constant buffer offsets on ATI and NVIDIA DX10 and DX11 GPUs must be a multiple of 256. In OpenGL, this can be queried via GL_UNIFORM_BUFFER_OFFSET_ALIGNMENT. --- src/gallium/drivers/i915/i915_screen.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'src/gallium/drivers/i915/i915_screen.c') diff --git a/src/gallium/drivers/i915/i915_screen.c b/src/gallium/drivers/i915/i915_screen.c index 1b3c4be12c7..00468602c09 100644 --- a/src/gallium/drivers/i915/i915_screen.c +++ b/src/gallium/drivers/i915/i915_screen.c @@ -208,6 +208,9 @@ i915_get_param(struct pipe_screen *screen, enum pipe_cap cap) case PIPE_CAP_QUADS_FOLLOW_PROVOKING_VERTEX_CONVENTION: return 0; + case PIPE_CAP_CONSTANT_BUFFER_OFFSET_ALIGNMENT: + return 16; + /* Features we can lie about (boolean caps). */ case PIPE_CAP_OCCLUSION_QUERY: return is->debug.lie ? 1 : 0; -- cgit v1.2.3
