* vulkan: Replace uses of maxMemoryAllocationSize and VK_WHOLE_SIZE Replace maxMemoryAllocationSize check with maxBufferSize when creating buffers. The maxMemoryAllocationSize limit is a "soft" limit and allocations can succeed beyond that limit. This allows > 4GB buffers to be allocated on some implementations (e.g. NVIDIA) and tensors this large can be used for im2col and mul_mat. For temporary buffers (prealloc_x/y/etc) check against maxStorageBufferRange. I'm not sure this check is ideal, but we always use these buffers as a single full size binding and the limit may be smaller than maxMemoryAllocationSize or maxBufferSize, so I think this is reasonable. Replace descriptor range uses of VK_WHOLE_SIZE with a manually computed range. The maxStorageBufferRange may be smaller than the maxBufferSize or maxMemoryAllocationSize (and the Vulkan spec warns about this in a note) and it's invalid usage if VK_WHOLE_SIZE computes a range larger than maxStorageBufferRange. With this change, it should be possible to generate videos using wan networks in stable-diffusion.cpp. * vulkan: Add env var GGML_VK_FORCE_MAX_BUFFER_SIZE and use stoull |
