From 42d9f2bb7bc21ff8c1a3fc4b4ceb4d294bccaabe Mon Sep 17 00:00:00 2001 From: Luca Barbieri Date: Thu, 15 Apr 2010 06:57:20 +0200 Subject: nouveau: replace vtxbuf/idxbuf caps with BO_ flags in nouveau_screen and fix uncached reads on nv3x Faster, simpler and more flexible. Also, we set those flags properly on nv3x so that we don't allocate buffers in GART. Since on AGP GART is uncached, OpenGL doesn't distinguish between vertex and index buffers, and we don't support hardware index buffers for now, this caused uncached reads. Also check bind and not usage for PIPE_BIND_* flags, got broken in the gallium-resources transition. --- src/gallium/drivers/nouveau/nouveau_screen.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'src/gallium/drivers/nouveau/nouveau_screen.h') diff --git a/src/gallium/drivers/nouveau/nouveau_screen.h b/src/gallium/drivers/nouveau/nouveau_screen.h index f32ecd0b69..747fd15acd 100644 --- a/src/gallium/drivers/nouveau/nouveau_screen.h +++ b/src/gallium/drivers/nouveau/nouveau_screen.h @@ -5,6 +5,11 @@ struct nouveau_screen { struct pipe_screen base; struct nouveau_device *device; struct nouveau_channel *channel; + + /* note that OpenGL doesn't distinguish between these, so + * these almost always should be set to the same value */ + unsigned vertex_buffer_flags; + unsigned index_buffer_flags; }; static inline struct nouveau_screen * -- cgit v1.2.3
