From c3974dc837b4a11a30603bb00fa1d346e721af59 Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Sun, 17 Oct 2010 11:45:49 -0700 Subject: r600g: set hardware pixel centers according to gl_rasterization_rules These were previously being left in the default (D3D) mode. This mean that triangles were drawn slightly incorrectly, but also because this state is relied on by the u_blitter code, all blits were half a pixel off. --- src/gallium/drivers/r600/r600d.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'src/gallium/drivers/r600/r600d.h') diff --git a/src/gallium/drivers/r600/r600d.h b/src/gallium/drivers/r600/r600d.h index a3cb5b8600..ae19bfb828 100644 --- a/src/gallium/drivers/r600/r600d.h +++ b/src/gallium/drivers/r600/r600d.h @@ -2100,6 +2100,10 @@ #define G_028C00_LAST_PIXEL(x) (((x) >> 10) & 0x1) #define C_028C00_LAST_PIXEL 0xFFFFFBFF #define R_028C04_PA_SC_AA_CONFIG 0x028C04 +#define R_028C08_PA_SU_VTX_CNTL 0x028C08 +#define S_028C08_PIX_CENTER_HALF(x) (((x) & 0x1) << 0) +#define G_028C08_PIX_CENTER_HALF(x) (((x) >> 0) & 0x1) +#define C_028C08_PIX_CENTER_HALF 0xFFFFFFFE #define R_028C1C_PA_SC_AA_SAMPLE_LOCS_MCTX 0x028C1C #define R_028C48_PA_SC_AA_MASK 0x028C48 #define R_028810_PA_CL_CLIP_CNTL 0x028810 -- cgit v1.2.3
