janis	5e4bc0ccf0	rendergraph: correct transient-resource aliasing with pooled placement ... Lifetimes derive from the real dependency ordering (retained DAG + compile-time happens-before closure), not command-index intervals. Aliasing is restricted to the single-queue contract; alias reuse is synchronized with memory/image barriers anchored at first-use commands. - renderer_device: aliasable shared allocations (CAN_ALIAS), memory- requirements queries incl. dedicated hints, offset-aware bind_buffer/image_memory2, grouped bind under one allocator lock - renderer_resources: unallocated resource creation, requirements cached in Allocation::Unmanaged (OnceLock), MemoryGroup pooling with intersecting memoryTypeBits, bind-time validation - renderer_rendergraph: retained dependency DAG, happens_before closure, batch lifetimes, Placement type, plan_placements with pooled aliasing (first-fit over offset-sorted ranges, pool classes split by bufferImageGranularity), alias-barrier construction, placement/bind error variants - perf: quadratic compile/resolve paths eliminated (per-resource indexing, frontier caching, backward-scan prune, cached recording index, recorder scratch reuse); single requirements query per resource through plan/validate/bind - design plan + GPU-gated validation tests	2026-10-27 01:57:27 +01:00
janis	e116851b90	feat: migrate GPU memory allocator from gpu-allocator to VMA (vk-mem) ... - Replace gpu-allocator with vk-mem 0.5.0 (VMA 3.3.0) in renderer_device - Add public GpuAllocation wrapper, MemoryLocation, AllocationDesc, and allocate_for_buffer/image + bind_buffer/image_memory helpers - Restrict CPU-mapped allocations to HOST_VISIBLE|HOST_COHERENT memory types - Handle guards: raw buffer/image handles owned before allocation so failure paths never leak - Use renderer_device::device::MemoryLocation across renderer, renderer_resources, and renderer_rendergraph; remove all gpu-allocator dependencies - Error on dedicated allocation below Vulkan 1.1 instead of silent downgrade - Add Send/Sync asserts, coherent-mapping and dedicated-allocation validation tests; update AGENTS.md docs	2026-10-26 13:44:17 +01:00
