From ac6334145ec8eef42505cdd727aed7fae0831e12 Mon Sep 17 00:00:00 2001 From: Christian König Date: Sun, 16 Jan 2011 01:45:06 +0100 Subject: r600d: fix some bugs added reworking literal handling If a literal slot isn't used it should be set to 0 instead of an uninitialized value. Also the channels for pre R700 trig functions were incorrect. And most important literals were not counted against ndw, resulting in an invalid force_add_cf detection. --- src/gallium/drivers/r600/r600_asm.c | 51 ++++++++++++++++++++++--------------- 1 file changed, 31 insertions(+), 20 deletions(-) (limited to 'src/gallium/drivers/r600/r600_asm.c') diff --git a/src/gallium/drivers/r600/r600_asm.c b/src/gallium/drivers/r600/r600_asm.c index beefd17ae2..a473fb29c4 100644 --- a/src/gallium/drivers/r600/r600_asm.c +++ b/src/gallium/drivers/r600/r600_asm.c @@ -846,9 +846,9 @@ static int merge_inst_groups(struct r600_bc *bc, struct r600_bc_alu *slots[5], { struct r600_bc_alu *prev[5]; struct r600_bc_alu *result[5] = { NULL }; - - uint32_t literal[4]; - unsigned nliteral = 0; + + uint32_t literal[4], prev_literal[4]; + unsigned nliteral = 0, prev_nliteral = 0; int i, j, r, src, num_src; int num_once_inst = 0; @@ -861,8 +861,12 @@ static int merge_inst_groups(struct r600_bc *bc, struct r600_bc_alu *slots[5], struct r600_bc_alu *alu; /* check number of literals */ - if (prev[i] && r600_bc_alu_nliterals(bc, prev[i], literal, &nliteral)) - return 0; + if (prev[i]) { + if (r600_bc_alu_nliterals(bc, prev[i], literal, &nliteral)) + return 0; + if (r600_bc_alu_nliterals(bc, prev[i], prev_literal, &prev_nliteral)) + return 0; + } if (slots[i] && r600_bc_alu_nliterals(bc, slots[i], literal, &nliteral)) return 0; @@ -923,6 +927,9 @@ static int merge_inst_groups(struct r600_bc *bc, struct r600_bc_alu *slots[5], /* looks like everything worked out right, apply the changes */ + /* undo adding previus literals */ + bc->cf_last->ndw -= align(prev_nliteral, 2); + /* sort instructions */ for (i = 0; i < 5; ++i) { slots[i] = result[i]; @@ -1108,11 +1115,6 @@ int r600_bc_add_alu_type(struct r600_bc *bc, const struct r600_bc_alu *alu, int if (!bc->cf_last->curr_bs_head) { bc->cf_last->curr_bs_head = nalu; } - /* at most 128 slots, one add alu can add 5 slots + 4 constants(2 slots) - * worst case */ - if (nalu->last && (bc->cf_last->ndw >> 1) >= 120) { - bc->force_add_cf = 1; - } /* number of gpr == the last gpr used in any alu */ for (i = 0; i < 3; i++) { if (nalu->src[i].sel >= bc->ngpr && nalu->src[i].sel < 128) { @@ -1133,6 +1135,8 @@ int r600_bc_add_alu_type(struct r600_bc *bc, const struct r600_bc_alu *alu, int /* process cur ALU instructions for bank swizzle */ if (nalu->last) { + uint32_t literal[4]; + unsigned nliteral; struct r600_bc_alu *slots[5]; r = assign_alu_units(bc, bc->cf_last->curr_bs_head, slots); if (r) @@ -1154,6 +1158,21 @@ int r600_bc_add_alu_type(struct r600_bc *bc, const struct r600_bc_alu *alu, int if (r) return r; + for (i = 0, nliteral = 0; i < 5; i++) { + if (slots[i]) { + r = r600_bc_alu_nliterals(bc, slots[i], literal, &nliteral); + if (r) + return r; + } + } + bc->cf_last->ndw += align(nliteral, 2); + + /* at most 128 slots, one add alu can add 5 slots + 4 constants(2 slots) + * worst case */ + if ((bc->cf_last->ndw >> 1) >= 120) { + bc->force_add_cf = 1; + } + bc->cf_last->prev2_bs_head = bc->cf_last->prev_bs_head; bc->cf_last->prev_bs_head = bc->cf_last->curr_bs_head; bc->cf_last->curr_bs_head = NULL; @@ -1455,16 +1474,6 @@ int r600_bc_build(struct r600_bc *bc) case (V_SQ_CF_ALU_WORD1_SQ_CF_INST_ALU_POP_AFTER << 3): case (V_SQ_CF_ALU_WORD1_SQ_CF_INST_ALU_POP2_AFTER << 3): case (V_SQ_CF_ALU_WORD1_SQ_CF_INST_ALU_PUSH_BEFORE << 3): - nliteral = 0; - LIST_FOR_EACH_ENTRY(alu, &cf->alu, list) { - r = r600_bc_alu_nliterals(bc, alu, literal, &nliteral); - if (r) - return r; - if (alu->last) { - cf->ndw += align(nliteral, 2); - nliteral = 0; - } - } break; case V_SQ_CF_WORD1_SQ_CF_INST_TEX: case V_SQ_CF_WORD1_SQ_CF_INST_VTX: @@ -1514,6 +1523,7 @@ int r600_bc_build(struct r600_bc *bc) case (V_SQ_CF_ALU_WORD1_SQ_CF_INST_ALU_POP2_AFTER << 3): case (V_SQ_CF_ALU_WORD1_SQ_CF_INST_ALU_PUSH_BEFORE << 3): nliteral = 0; + memset(literal, 0, sizeof(literal)); LIST_FOR_EACH_ENTRY(alu, &cf->alu, list) { r = r600_bc_alu_nliterals(bc, alu, literal, &nliteral); if (r) @@ -1539,6 +1549,7 @@ int r600_bc_build(struct r600_bc *bc) bc->bytecode[addr++] = literal[i]; } nliteral = 0; + memset(literal, 0, sizeof(literal)); } } break; -- cgit v1.2.3
