From 6057d7b7b58102bf7c3c4ecb08c1b7261f299efa Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Thu, 13 Jun 2013 10:10:17 +0800 Subject: [PATCH] ilo: re-emit states that involve resources Even with hardware contexts, since we do not pin resources, we have to re-emit the states so that the resources are referenced (by cp->bo) and their offsets are updated in case they are moved. This also allows us to elimiate cp flush in is_bo_busy(). --- src/gallium/drivers/ilo/ilo_3d_pipeline_gen6.c | 23 +++++++++++++++++++---- src/gallium/drivers/ilo/ilo_3d_pipeline_gen6.h | 1 + src/gallium/drivers/ilo/ilo_3d_pipeline_gen7.c | 12 +++--------- src/gallium/drivers/ilo/ilo_transfer.c | 8 -------- 4 files changed, 23 insertions(+), 21 deletions(-) diff --git a/src/gallium/drivers/ilo/ilo_3d_pipeline_gen6.c b/src/gallium/drivers/ilo/ilo_3d_pipeline_gen6.c index e4315df..c60fc01 100644 --- a/src/gallium/drivers/ilo/ilo_3d_pipeline_gen6.c +++ b/src/gallium/drivers/ilo/ilo_3d_pipeline_gen6.c @@ -210,7 +210,8 @@ gen6_pipeline_common_base_address(struct ilo_3d_pipeline *p, struct gen6_pipeline_session *session) { /* STATE_BASE_ADDRESS */ - if (session->state_bo_changed || session->instruction_bo_changed) { + if (session->state_bo_changed || session->instruction_bo_changed || + session->batch_bo_changed) { if (p->dev->gen == ILO_GEN(6)) gen6_wa_pipe_control_post_sync(p, false); @@ -396,13 +397,14 @@ gen6_pipeline_vf(struct ilo_3d_pipeline *p, struct gen6_pipeline_session *session) { /* 3DSTATE_INDEX_BUFFER */ - if (DIRTY(INDEX_BUFFER)) { + if (DIRTY(INDEX_BUFFER) || session->batch_bo_changed) { p->gen6_3DSTATE_INDEX_BUFFER(p->dev, &ilo->ib.state, session->info->primitive_restart, p->cp); } /* 3DSTATE_VERTEX_BUFFERS */ - if (DIRTY(VERTEX_BUFFERS) || DIRTY(VERTEX_ELEMENTS)) { + if (DIRTY(VERTEX_BUFFERS) || DIRTY(VERTEX_ELEMENTS) || + session->batch_bo_changed) { p->gen6_3DSTATE_VERTEX_BUFFERS(p->dev, ilo->vb.states, ilo->vb.enabled_mask, ilo->ve, p->cp); } @@ -714,7 +716,7 @@ gen6_pipeline_wm_depth(struct ilo_3d_pipeline *p, struct gen6_pipeline_session *session) { /* 3DSTATE_DEPTH_BUFFER and 3DSTATE_CLEAR_PARAMS */ - if (DIRTY(FRAMEBUFFER)) { + if (DIRTY(FRAMEBUFFER) || session->batch_bo_changed) { if (p->dev->gen == ILO_GEN(6)) { gen6_wa_pipe_control_post_sync(p, false); gen6_wa_pipe_control_wm_depth_flush(p); @@ -1298,11 +1300,24 @@ gen6_pipeline_prepare(const struct ilo_3d_pipeline *p, if (session->hw_ctx_changed) { /* these should be enough to make everything uploaded */ + session->batch_bo_changed = true; session->state_bo_changed = true; session->instruction_bo_changed = true; session->prim_changed = true; } else { + /* + * Any state that involves resources needs to be re-emitted when the + * batch bo changed.
