From bc398f908f8765edee48150dc7e3f24874bb03d9 Mon Sep 17 00:00:00 2001 From: Vadim Girlin Date: Tue, 15 Jan 2013 19:36:32 +0100 Subject: [PATCH] radeonsi: improve flushed depth texture handling MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Use r600_resource_texture::flished_depth_texture for GPU access, and allocate it in the VRAM. For transfers we'll allocate texture in the GTT and store it in the r600_transfer::staging. Improves performance when flushed depth texture is frequently used by the GPU, e.g. in Lightsmark [ Ported from r600g commit 37708479608af877986b76302a9c92611d1e23d0 ] Signed-off-by: Michel Dänzer --- src/gallium/drivers/radeonsi/r600_blit.c | 31 ++++--- src/gallium/drivers/radeonsi/r600_resource.h | 10 ++- src/gallium/drivers/radeonsi/r600_texture.c | 123 ++++++++++++++------------- src/gallium/drivers/radeonsi/radeonsi_pipe.h | 4 +- src/gallium/drivers/radeonsi/si_state.c | 13 +-- 5 files changed, 100 insertions(+), 81 deletions(-) diff --git a/src/gallium/drivers/radeonsi/r600_blit.c b/src/gallium/drivers/radeonsi/r600_blit.c index f368292..d600962 100644 --- a/src/gallium/drivers/radeonsi/r600_blit.c +++ b/src/gallium/drivers/radeonsi/r600_blit.c @@ -114,13 +114,17 @@ static unsigned u_num_layers(struct pipe_resource *r, unsigned level) } } -void si_blit_uncompress_depth(struct pipe_context *ctx, struct r600_resource_texture *texture) +void si_blit_uncompress_depth(struct pipe_context *ctx, + struct r600_resource_texture *texture, + struct r600_resource_texture *staging) { struct r600_context *rctx = (struct r600_context *)ctx;
