Zebediah Figura : wined3d: Submit command buffers after 512 draw or dispatch commands.

07 May '24

Module: wine Branch: master Commit: cb723c6dd3baf13583b0bde2fc71191b86100229 URL: https://gitlab.winehq.org/wine/wine/-/commit/cb723c6dd3baf13583b0bde2fc7119… Author: Zebediah Figura <zfigura(a)codeweavers.com> Date: Wed Apr 24 18:30:08 2024 -0500 wined3d: Submit command buffers after 512 draw or dispatch commands. This improves performance for the game "Grounded", on a AMD Radeon RX 6700 XT, with radv from Mesa 22.3.6. Testing was done with the "cb_access_map_w" option enabled, which also improves performance with the game by itself. Grounded generally makes about 4000 draw calls per frame, which seems not atypical. This change makes it submit at most an extra 8 times per frame, but in practice due to WINED3D_PERIODIC_SUBMIT_MAX_BUFFERS it submits less (usually only 2-3). The most demanding game I've seen made about 20,000 draw calls per frame, at which point the overhead of adapter_vk_draw_primitive() itself becomes a serious bottleneck. For such a game we would submit 40 more times per frame with these settings, although WINED3D_PERIODIC_SUBMIT_MAX_BUFFERS means we would likely submit less than that. In any case if submission itself becomes a bottleneck, we should offload it to a separate thread. Credit goes to Philip Rebohle and his work on DXVK for helping me to notice that periodic submission might make a difference. --- dlls/wined3d/adapter_vk.c | 4 ++++ dlls/wined3d/context_vk.c | 35 ++++++++++++++++++++++++++++++++++- dlls/wined3d/wined3d_vk.h | 3 +++ 3 files changed, 41 insertions(+), 1 deletion(-) diff --git a/dlls/wined3d/adapter_vk.c b/dlls/wined3d/adapter_vk.c index 418b67de8b6..39b263872ed 100644 --- a/dlls/wined3d/adapter_vk.c +++ b/dlls/wined3d/adapter_vk.c @@ -1807,6 +1807,8 @@ static void adapter_vk_draw_primitive(struct wined3d_device *device, context_vk->c.transform_feedback_active = 0; } + ++context_vk->command_buffer_work_count; + context_release(&context_vk->c); } @@ -1851,6 +1853,8 @@ static void adapter_vk_dispatch_compute(struct wined3d_device *device, VK_CALL(vkCmdPipelineBarrier(vk_command_buffer, VK_PIPELINE_STAGE_COMPUTE_SHADER_BIT, VK_PIPELINE_STAGE_ALL_GRAPHICS_BIT, 0, 0, NULL, 0, NULL, 0, NULL)); + ++context_vk->command_buffer_work_count; + context_release(&context_vk->c); } diff --git a/dlls/wined3d/context_vk.c b/dlls/wined3d/context_vk.c index 377c437ee09..200dcb57b7f 100644 --- a/dlls/wined3d/context_vk.c +++ b/dlls/wined3d/context_vk.c @@ -1771,6 +1771,37 @@ void wined3d_context_vk_cleanup(struct wined3d_context_vk *context_vk) wined3d_context_cleanup(&context_vk->c); } +/* In general we only submit when necessary or when a frame ends.

Part of beginning a render pass involves executing an RTV barrier, which itself needs to call wined3d_context_vk_get_command_buffer(). However, that function may decide to submit the command buffer, in order to prevent resource buildup, or [in the future] because it has been some length of time since the last submission. Therefore we cannot retrieve and store a VkCommandBuffer pointer before executing an RTV barrier and then use it later. --- dlls/wined3d/context_vk.c | 19 +++++++++++-------- 1 file changed, 11 insertions(+), 8 deletions(-) diff --git a/dlls/wined3d/context_vk.c b/dlls/wined3d/context_vk.c index dc793a839bb..377c437ee09 100644 --- a/dlls/wined3d/context_vk.c +++ b/dlls/wined3d/context_vk.c @@ -2699,7 +2699,7 @@ static bool wined3d_context_vk_update_graphics_pipeline_key(struct wined3d_conte } static bool wined3d_context_vk_begin_render_pass(struct wined3d_context_vk *context_vk, - VkCommandBuffer vk_command_buffer, const struct wined3d_state *state, const struct wined3d_vk_info *vk_info) + const struct wined3d_state *state, const struct wined3d_vk_info *vk_info) { struct wined3d_device_vk *device_vk = wined3d_device_vk(context_vk->c.device); VkClearValue clear_values[WINED3D_MAX_RENDER_TARGETS + 1]; @@ -2709,6 +2709,7 @@ static bool wined3d_context_vk_begin_render_pass(struct wined3d_context_vk *cont struct wined3d_rendertarget_view *view; const VkPhysicalDeviceLimits *limits; struct wined3d_query_vk *query_vk; + VkCommandBuffer vk_command_buffer; VkRenderPassBeginInfo begin_info; unsigned int attachment_count, i; struct wined3d_texture *texture; @@ -2814,6 +2815,12 @@ static bool wined3d_context_vk_begin_render_pass(struct wined3d_context_vk *cont ++attachment_count; } + if (!(vk_command_buffer = wined3d_context_vk_get_command_buffer(context_vk))) + { + ERR("Failed to get command buffer.\n"); + return false; + } + if (!(context_vk->vk_render_pass = wined3d_context_vk_get_render_pass(context_vk, &state->fb, ARRAY_SIZE(state->fb.render_targets), !!state->fb.depth_stencil, 0))) { @@ -3772,19 +3779,15 @@ VkCommandBuffer wined3d_context_vk_apply_draw_state(struct wined3d_context_vk *c wined3d_context_vk_load_buffers(context_vk, state, indirect_vk, indexed); - if (!(vk_command_buffer = wined3d_context_vk_get_command_buffer(context_vk))) - { - ERR("Failed to get command buffer.\n"); - return VK_NULL_HANDLE; - } - if (wined3d_context_is_graphics_state_dirty(&context_vk->c, STATE_FRAMEBUFFER)) wined3d_context_vk_end_current_render_pass(context_vk); - if (!wined3d_context_vk_begin_render_pass(context_vk, vk_command_buffer, state, vk_info)) + + if (!wined3d_context_vk_begin_render_pass(context_vk, state, vk_info)) { ERR("Failed to begin render pass.\n"); return VK_NULL_HANDLE; } + vk_command_buffer = context_vk->current_command_buffer.vk_command_buffer; while (invalidate_rt) {
