From afa925066c158ac49e3b0f883f67debd8545bf26 Mon Sep 17 00:00:00 2001 From: Marek Olšák Date: Mon, 2 Aug 2010 17:14:07 +0200 Subject: r300g: fix hardlock when using more than one stuffed sprite coords If texture coordinates come from the vertex shader, there are always 4 components in the rasterizer input packet, but if the coordinates are stuffed (like for point sprites), there are only 2 or 3 components (based on GB_ENABLE) and if we rasterize more, it locks up. --- src/gallium/drivers/r300/r300_state_derived.c | 38 ++++++++++++++------------- 1 file changed, 20 insertions(+), 18 deletions(-) (limited to 'src/gallium/drivers/r300/r300_state_derived.c') diff --git a/src/gallium/drivers/r300/r300_state_derived.c b/src/gallium/drivers/r300/r300_state_derived.c index a85db27064..66f64f0f6a 100644 --- a/src/gallium/drivers/r300/r300_state_derived.c +++ b/src/gallium/drivers/r300/r300_state_derived.c @@ -213,19 +213,19 @@ static void r300_rs_tex(struct r300_rs_block* rs, int id, int ptr, enum r300_rs_swizzle swiz) { if (swiz == SWIZ_X001) { - rs->ip[id] |= R300_RS_TEX_PTR(ptr*4) | + rs->ip[id] |= R300_RS_TEX_PTR(ptr) | R300_RS_SEL_S(R300_RS_SEL_C0) | R300_RS_SEL_T(R300_RS_SEL_K0) | R300_RS_SEL_R(R300_RS_SEL_K0) | R300_RS_SEL_Q(R300_RS_SEL_K1); } else if (swiz == SWIZ_XY01) { - rs->ip[id] |= R300_RS_TEX_PTR(ptr*4) | + rs->ip[id] |= R300_RS_TEX_PTR(ptr) | R300_RS_SEL_S(R300_RS_SEL_C0) | R300_RS_SEL_T(R300_RS_SEL_C1) | R300_RS_SEL_R(R300_RS_SEL_K0) | R300_RS_SEL_Q(R300_RS_SEL_K1); } else { - rs->ip[id] |= R300_RS_TEX_PTR(ptr*4) | + rs->ip[id] |= R300_RS_TEX_PTR(ptr) | R300_RS_SEL_S(R300_RS_SEL_C0) | R300_RS_SEL_T(R300_RS_SEL_C1) | R300_RS_SEL_R(R300_RS_SEL_C2) | @@ -261,23 +261,21 @@ static void r500_rs_col_write(struct r300_rs_block* rs, int id, int fp_offset) static void r500_rs_tex(struct r300_rs_block* rs, int id, int ptr, enum r300_rs_swizzle swiz) { - int rs_tex_comp = ptr*4; - if (swiz == SWIZ_X001) { - rs->ip[id] |= R500_RS_SEL_S(rs_tex_comp) | + rs->ip[id] |= R500_RS_SEL_S(ptr) | R500_RS_SEL_T(R500_RS_IP_PTR_K0) | R500_RS_SEL_R(R500_RS_IP_PTR_K0) | R500_RS_SEL_Q(R500_RS_IP_PTR_K1); } else if (swiz == SWIZ_XY01) { - rs->ip[id] |= R500_RS_SEL_S(rs_tex_comp) | - R500_RS_SEL_T(rs_tex_comp + 1) | + rs->ip[id] |= R500_RS_SEL_S(ptr) | + R500_RS_SEL_T(ptr + 1) | R500_RS_SEL_R(R500_RS_IP_PTR_K0) | R500_RS_SEL_Q(R500_RS_IP_PTR_K1); } else { - rs->ip[id] |= R500_RS_SEL_S(rs_tex_comp) | - R500_RS_SEL_T(rs_tex_comp + 1) | - R500_RS_SEL_R(rs_tex_comp + 2) | - R500_RS_SEL_Q(rs_tex_comp + 3); + rs->ip[id] |= R500_RS_SEL_S(ptr) | + R500_RS_SEL_T(ptr + 1) | + R500_RS_SEL_R(ptr + 2) | + R500_RS_SEL_Q(ptr + 3); } rs->inst[id] |= R500_RS_INST_TEX_ID(id); } @@ -305,7 +303,7 @@ static void r300_update_rs_block(struct r300_context *r300) struct r300_shader_semantics *vs_outputs = &vs->outputs; struct r300_shader_semantics *fs_inputs = &r300_fs(r300)->shader->inputs; struct r300_rs_block rs = {0}; - int i, col_count = 0, tex_count = 0, fp_offset = 0, count, loc = 0; + int i, col_count = 0, tex_count = 0, fp_offset = 0, count, loc = 0, tex_ptr = 0; void (*rX00_rs_col)(struct r300_rs_block*, int, int, enum r300_rs_swizzle); void (*rX00_rs_col_write)(struct r300_rs_block*, int, int); void (*rX00_rs_tex)(struct r300_rs_block*, int, int, enum r300_rs_swizzle); @@ -393,8 +391,9 @@ static void r300_update_rs_block(struct r300_context *r300) stream_loc_notcl[loc++] = 6 + tex_count; /* Rasterize it. */ - rX00_rs_tex(&rs, tex_count, tex_count, SWIZ_XYZW); + rX00_rs_tex(&rs, tex_count, tex_ptr, SWIZ_XYZW); tex_count++; + tex_ptr += 4; } } } @@ -412,7 +411,7 @@ static void r300_update_rs_block(struct r300_context *r300) } /* Rasterize it. */ - rX00_rs_tex(&rs, tex_count, tex_count, + rX00_rs_tex(&rs, tex_count, tex_ptr, sprite_coord ?
