            Bug ID: 273028
           Summary: [WebGPU] mapAsync shouldn’t be calling getMappedRange
                    on the entire buffer
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebGPU
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mwyrzykowski at apple.com

[WebGPU] mapAsync shouldn’t be calling getMappedRange on the entire buffer. The buffer could be 1GB for example, but the receiver only wants to read 16 bytes, we would pass 1GB from the GPU process to the web process unnecessarily.
