  "message": "vulkan: Split multi-layer buffer copies on Maleoon\n\nHuawei Maleoon drivers mis-stride multi-layer buffer\u003c-\u003eimage copies: in\na single VkBufferImageCopy region with layerCount \u003e 1 and a padded\nbufferImageHeight, only the first array layer / depth slice lands at the\ncorrect buffer offset; every later layer is read/written at the wrong\noffset and comes back corrupted.\n\nAdd a VulkanSplitBufferTextureCopyForArrayLayers toggle that emits one\ncopy region per layer, each with layerCount \u003d 1 and an explicit\nper-layer buffer offset, so the driver never strides between layers\nitself. The toggle is enabled by default only on Maleoon and applies to\nboth CopyBufferToTexture and CopyTextureToBuffer.\n\nFixes the WebGPU CTS image_copy clusters on Mate60 / Maleoon 910:\napi,operation,command_buffer,image_copy:mip_levels:*\napi,operation,command_buffer,image_copy:rowsPerImage_and_bytesPerRow:*\napi,operation,command_buffer,image_copy:rowsPerImage_and_bytesPerRow_depth_stencil:*\n\nBug: 520126486, 520126487\nChange-Id: Ic913e3ca25c84169f9ff19d974e86ecf0b61f650\nReviewed-on: https://dawn-review.googlesource.com/c/dawn/+/317116\nReviewed-by: Brandon Jones \u003cbajones@chromium.org\u003e\nReviewed-by: Kai Ninomiya \u003ckainino@chromium.org\u003e\nCommit-Queue: Kai Ninomiya \u003ckainino@chromium.org\u003e\n",
