Delete branch "eden-emu/eden:master"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
1. Improves stencil handling: - Adds surface type detection to distinguish between color, depth, stencil, and depth-stencil formats - Only enables stencil load/store operations for surfaces that actually contain stencil data - Avoids unnecessary stencil operations for non-stencil formats (DONT_CARE) 2. Fixes read-after-write (RAW) synchronization hazards: - Adds a subpass self-dependency (subpass 0 → subpass 0) - Synchronizes color/depth writes with subsequent shader reads - Uses VK_DEPENDENCY_BY_REGION_BIT for efficient synchronization - Covers all possible relevant stages, • src: Color output + Early/Late fragment tests • dst: Fragment shader • Access: Write → Read transitions here is what hazard looks like [1147.550616] Render.Vulkan <Critical> video_core/vulkan_common/vulkan_debug_callback.cpp:DebugUtilCallback:55: Validation Error: [ SYNC-HAZARD-READ-AFTER-WRITE ] Object 0: handle = 0x7409630000000192, type = VK_OBJECT_TYPE_IMAGE_VIEW; | MessageID = 0xe4d96472 | vkCmdDrawIndexed: Hazard READ_AFTER_WRITE for VkImageView 0x7409630000000192[], in VkCommandBuffer 0xb400007cb003ea70[], and VkPipeline 0x44d3470000000213[], VkDescriptorSet 0x0[], type: VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER, imageLayout: VK_IMAGE_LAYOUT_GENERAL, binding #2, index 0.
