The AdrenoMetal repository was NativeMetal; the accelerator's include of ../NativeMetal/OriginalAcceleratorABI.h resolved only beside a leftover clone of the old name and fails on a clean tree.

// The registry-visible accelerator for the original Metal discovery (IOServiceMatching("IOAcceleratorES") ->
|
|
// MetalPluginName -> /System/Library/Extensions/<name>.bundle). It derives from the original IOAcceleratorES base exactly as
|
|
// qualified in drivers/AdrenoMetal/OriginalAcceleratorABI.h: the original base has no operational overrides, so the only
|
|
// virtuals this class adds are newUserClient and the property reads below (diagnostic counting only). Its static initializer
|
|
// is staged out of __mod_init_func and run by the board probe after the original IOGPUFamily kext has loaded, because the
|
|
// parent metaclass does not exist before that. The class is named after the Apple accelerator class on purpose, so original
|
|
// sandbox profiles that name the service class accept the Adreno plugin's open; the Apple AGX kext is never loaded here.
