[Webkit-unassigned] [Bug 198684] [WebGPU] Performance: Cache staging MTLBuffers used by GPUBuffer.unmap

[bugzilla-daemon at webkit.org]

https://bugs.webkit.org/show_bug.cgi?id=198684

--- Comment #3 from Justin Fan <justin_fan at apple.com> ---
Small addition: Specify MTLResourceCPUCacheModeWriteCombined in the creation option for these staging buffers, as the CPU never reads from them.
