From 0219b995003516aa6d2f8bb5ce6e0b02df2e835b Mon Sep 17 00:00:00 2001 From: Alyssa Rosenzweig Date: Tue, 11 Jun 2019 14:21:14 -0700 Subject: [PATCH] panfrost: Handle missing texture case In some cases, Gallium can give us bad info about the texture count, counting some NULL textures. We pass Gallium's info to the hardware blindly, which can confuse the hardware in edge cases. This patch adjusts accordingly. --- src/gallium/drivers/panfrost/pan_context.c | 47 ++++++++++++++++++------------ 1 file changed, 29 insertions(+), 18 deletions(-) diff --git a/src/gallium/drivers/panfrost/pan_context.c b/src/gallium/drivers/panfrost/pan_context.c index 09bded8..8dbdc84 100644 --- a/src/gallium/drivers/panfrost/pan_context.c +++ b/src/gallium/drivers/panfrost/pan_context.c @@ -900,23 +900,27 @@ panfrost_upload_sampler_descriptors(struct panfrost_context *ctx) size_t desc_size = sizeof(struct mali_sampler_descriptor); for (int t = 0; t <= PIPE_SHADER_FRAGMENT; ++t) { - if (!ctx->sampler_count[t]) continue; + mali_ptr upload = 0; - size_t transfer_size = desc_size * ctx->sampler_count[t]; + if (ctx->sampler_count[t] && ctx->sampler_view_count[t]) { + size_t transfer_size = desc_size * ctx->sampler_count[t]; - struct panfrost_transfer transfer = - panfrost_allocate_transient(ctx, transfer_size); + struct panfrost_transfer transfer = + panfrost_allocate_transient(ctx, transfer_size); - struct mali_sampler_descriptor *desc = - (struct mali_sampler_descriptor *) transfer.cpu; + struct mali_sampler_descriptor *desc = + (struct mali_sampler_descriptor *) transfer.cpu; - for (int i = 0; i < ctx->sampler_count[t]; ++i) - desc[i] = ctx->samplers[t][i]->hw; + for (int i = 0; i < ctx->sampler_count[t]; ++i) + desc[i] = ctx->samplers[t][i]->hw; + + upload = transfer.gpu; + } if (t == PIPE_SHADER_FRAGMENT) - ctx->payload_tiler.postfix.sampler_descriptor = transfer.gpu; + ctx->payload_tiler.postfix.sampler_descriptor = upload; else if (t == PIPE_SHADER_VERTEX) - ctx->payload_vertex.postfix.sampler_descriptor = transfer.gpu; + ctx->payload_vertex.postfix.sampler_descriptor = upload; else assert(0); } @@ -977,16 +981,17 @@ static void panfrost_upload_texture_descriptors(struct panfrost_context *ctx) { for (int t = 0; t <= PIPE_SHADER_FRAGMENT; ++t) { - /* Shortcircuit */ - if (!ctx->sampler_view_count[t]) continue; + mali_ptr trampoline = 0; - uint64_t trampolines[PIPE_MAX_SHADER_SAMPLER_VIEWS]; + if (ctx->sampler_view_count[t]) { + uint64_t trampolines[PIPE_MAX_SHADER_SAMPLER_VIEWS]; - for (int i = 0; i < ctx->sampler_view_count[t]; ++i) - trampolines[i] = - panfrost_upload_tex(ctx, ctx->sampler_views[t][i]); + for (int i = 0; i < ctx->sampler_view_count[t]; ++i) + trampolines[i] = + panfrost_upload_tex(ctx, ctx->sampler_views[t][i]); - mali_ptr trampoline = panfrost_upload_transient(ctx, trampolines, sizeof(uint64_t) * ctx->sampler_view_count[t]); + trampoline = panfrost_upload_transient(ctx, trampolines, sizeof(uint64_t) * ctx->sampler_view_count[t]); + } if (t == PIPE_SHADER_FRAGMENT) ctx->payload_tiler.postfix.texture_trampoline = trampoline; @@ -2128,7 +2133,13 @@ panfrost_set_sampler_views( assert(start_slot == 0); - ctx->sampler_view_count[shader] = num_views; + unsigned new_nr = 0; + for (unsigned i = 0; i < num_views; ++i) { + if (views[i]) + new_nr = i + 1; + } + + ctx->sampler_view_count[shader] = new_nr; memcpy(ctx->sampler_views[shader], views, num_views * sizeof (void *)); ctx->dirty |= PAN_DIRTY_TEXTURES; -- 2.7.4
