From 4a26454e979251db25bab68685835fa32c099429 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Sun, 22 Apr 2012 20:51:43 +0100 Subject: [PATCH] r600g: bypass alpha for integer types (v2) This moves the alpha test control to derived state and disables alpha testing for integer fbs. fbo-blending test in piglit gets further when we do this (not a pass but less fail). v2: drop the fb_sx_alpha_test_control Signed-off-by: Dave Airlie --- src/gallium/drivers/r600/evergreen_state.c | 7 ++++++- src/gallium/drivers/r600/r600_pipe.h | 2 ++ src/gallium/drivers/r600/r600_state.c | 7 ++++++- src/gallium/drivers/r600/r600_state_common.c | 4 ++++ 4 files changed, 18 insertions(+), 2 deletions(-) diff --git a/src/gallium/drivers/r600/evergreen_state.c b/src/gallium/drivers/r600/evergreen_state.c index 97a27d2..82313ea 100644 --- a/src/gallium/drivers/r600/evergreen_state.c +++ b/src/gallium/drivers/r600/evergreen_state.c @@ -796,11 +796,11 @@ static void *evergreen_create_dsa_state(struct pipe_context *ctx, alpha_test_control |= S_028410_ALPHA_TEST_ENABLE(1);
